Dual Setpoint Mode now comes standard with City Multi VRF and HVRF Systems

Tuesday 28th of April 2020
Modern buildings are now being designed with more and more requirements for occupant comfort and energy efficiency. User comfort is now seen as an increased source of productivity and reduction in illness. Rising energy costs and a drive to lower energy use are motivating building operators to decrease power consumption.

Single Setpoint found in traditional HVAC systems often restricts comfort

Standard Automatic Mode offers only one setpoint to the user. This would often prove problematic as the comfort of the inhabitant would be influenced by not only the space temperature but also the temperature of the incoming air from the air conditioning system. One setpoint with warm or recirculated air would be comfortable; however, the same setpoint with cool circulated air would feel uncomfortable. Add to this the requirement for the changeover from heating to cooling needing a deadband to prevent cycling and you would end up with a sudden drop in temperature once the mode changes.

Dual Setpoint is the next generation in comfort and energy consumption control

Dual Setpoint offers a solution to this issue by allowing a different heating and cooling setpoint with the system changing mode in between the two setpoints. This control is also ideal for large open spaces where a number of occupants are present with different comfort requirements.

By introducing a deadband between the heating and cooling setpoints, energy savings are offered by preventing over-heating and/or cooling the space.

Dual Setpoint – now built-in to City Multi Systems for ease of use

Previously a high-level BMS or additional controls were required to achieve this level of comfort. However, now this functionality is inbuilt in Mitsubishi Electric City Multi VRF and HVRF Heat Recovery Systems.

Introducing City Multi R32 Hybrid VRF – The Revolution of Water.

Tuesday 8th of October 2019
The HVAC industry is currently seeing huge pressure put on the use of HFC refrigerants, primarily R410A in the air conditioning market. This pressure is systemic of the global drive to reduce our industry’s Global Warming Potential by reducing the amount of high GWP refrigerant we are supplying into the global market.

The New Zealand Government, having adopted the Kigali Amendment to the Montreal Protocol, has cemented us in the drive to reduce our global warming potential. This is impacting the decision-making process when designing HVAC systems, from the global research and design or manufacturing, all the way down to the type of unit we install into our homes and businesses here in New Zealand.

The market has seen the wider adoption of R32 refrigerant on a domestic level, and the increasing immergence of low GWP refrigerants such as R513 or R1234ze in the chilled water market, but the question still remains around the VRF / VRV market as to how we tackle low GWP refrigerants.

Mitsubishi Electric have been at the forefront of the VRF market for many years with the world’s first 2 pipe heat recovery VRF system. In 2014, they pioneered the world’s first Hybrid VRF (HVRF) system, incorporating VRF Technology into a hydronic-based fan coil system, providing the market with a 2 pipe heat recovery hydronic solution.

Again in 2019, Mitsubishi Electric have led the way by incorporating a low GWP refrigerant with Hybrid VRF giving the lowest GWP VRF-based system available. With a GWP potential as low as 20% of a traditional R410A VRF system, and no risk of refrigerant leakage into occupied spaces, R32 HVRF provides a convenient, modular VRF solution with advantages otherwise found in a 4 pipe heat recovery hydronic system.

Hybrid VRF is a simple premise. Using a traditional VRF condenser as the base of the design, engineers set about developing a hybrid branch controller which uses the same heat recovery principles of a traditional DX system. What sets this system apart is that it incorporates four plate heat exchangers as the condensing and evaporating devices to allow heat recovery to water rather than air.

By using the heat exchangers to absorb and impart heat to the water circuitry, HVRF is able to cool, heat or simultaneously heat and cool the circulated water out to the field devices. The Hybrid Branch Controller (BC) incorporates two separate variable speed DC pumps and manifold systems to direct the heated or cooled water to the required fan coil units. Using only two pipes between the branch controller and each indoor, while still being able to deliver both heating and cooling.

Coupled to a proprietary control system which considers the heating and cooling demand, as well as the flow rate of the system, there is no need for a complicated bespoke control and valve system with Hybrid VRF as there is with a traditional hydronic heat recovery system. This makes Hybrid VRF a very easy-to-use package.

R32 Hybrid VRF is the new era of VRF in the market. Mitsubishi Electric have strived to design a system which not only meets the legislative requirements being imposed on the market today, but also meets the future requirements that our market will have to adhere to.

The demand for high energy efficiencies, low global warming potential and improved corporate social responsibility is increasing. As a result, regardless whether operating on a global, national or regional basis, all businesses are being forced to look at their own buildings and how their decisions on capital plant will impact them over the life span of the product. As such R410A systems are becoming less viable. The cost of refrigerant is only increasing, with R410A cost per kilogram climbing rapidly based on the high GWP and the ETS tax imposed.

As business owners, design engineers, installers and suppliers of HVAC systems in New Zealand, it is our duty to provide the developers and building owners a robust future-proof solution to best suit their building and occupants needs. It is imperative we observe occupant safety and ensure our decisions will not have a lasting impact on our environment for the future.

BDT and Mitsubishi Electric are dedicated to leading the market with innovative products and initiatives which ensure our social corporate responsibilities are upheld; protecting ourselves, our stakeholders and the public.

MEHIT Offers Lower GWP Refrigerants on Chillers and Heat Pumps

Wednesday 4th of September 2019
Mitsubishi Electric Hydronics & IT Cooling Systems S.p.A (MEHIT) introduces the use of lower GWP refrigerants R513A and R454B on its chillers and heat pumps.

MEHIT, which was formed in 2015 from the merger of the former Climaveneta and DeLclima businesses, has selected Opteon XP10 (R513A) for its screw and centrifugal oil-free chiller platform, and Opteon XL41 (R454B) for its multi-scroll platform, produced in Europe.

This is seen as part of an environmental initiative to provide efficient, sustainable, and long-term solutions to the chiller market ahead of the next 2021 European F-Gas Cap phase down and will be implemented from this year onwards.

R513A is a non-toxic, non-flammable A1 refrigerant with a GWP of 631, composed of a blend of 44% R134a and 56% R1234yf.

R454B is a “mildly flammable” A2L refrigerant blend of 68.9% R32 and 31.1% 1234yf. It has a GWP of 466 and offers improved energy efficiency, similar capacity, and excellent design compatibility.

This shift will help the chiller and heat pump industry move towards more environmentally sustainable refrigerant solutions while meeting long-term regulatory requirements and delivering consistent performance.

MEHIT has a long track record in eco-friendly solutions and was among the very first to promote, to the most eco-conscious customers, screw and centrifugal chillers based on HFOs; namely R1234ze with near-to-zero GWP, while also combining superior efficiencies.

MEHIT used its state-of-the-art research and development centres and its cooperation with Mitsubishi Electric Group laboratories to conduct in-depth evaluations of different refrigerant and components alternatives.

Currently, MEHIT screw chillers are available in R513A and R1234ze versions, and all its screw heat pumps and simultaneous heating and cooling units in R513A. MEHIT selected R454B for multi-scroll chillers and heat pumps. It was seen as the best solution to minimise environmental impact and energy use, while also improving performance. Some units utilising Mitsubishi Electric Inverter Compressors will be made available with R32.

As a R410A replacement for the multi-scroll chiller and heat pump ranges, MEHIT decided to also lead the change to lower GWP refrigerants. Therefore, the product line for the R454B version of the multi-scroll chillers is scheduled for release in the first quarter of 2020.

No other company is offering such a wide choice to the market. We are making this big effort, recognising customers at this point in time have different needs and constraints.

HVRF – The Way of the Future

Thursday 11th of April 2019
In July 2017 we showcased Hybrid VRF at our City Multi Conference in Wellington. Since then, we have been busy working with consultants and contractors across New Zealand, with many finding relevant applications for this innovative technology in their HVAC building design. One of the biggest reasons consultants are actively choosing HVRF has been to eliminate refrigeration in the building space, especially in medical facilities.

Ideal for Medical Practice Applications

Of all of the HVRF Systems sold in New Zealand to date, 33% have been installed at medical centres. Doctor-patient privacy is one of the key requirements for medical centres where consulting rooms are often fully sealed.

Refrigerant Concentration Limitations

These small footprint medical consultation rooms dictate the limitations on the refrigerant concentration allowed due to safety regulations, as laid out in ASNZS5149. In turn, additional refrigerant leak detectors are required, creating increased expenditure not just in capital costs but also ongoing maintenance of leak detection systems.

HVRF Mitigates These Factors as Only Water is Passed Through the Indoor Units

In the new amendments to the legislation, not only has the critical concentration limit been reduced, but under circumstances where refrigerant leak detectors are required, this is no longer the only measure that is acceptable according to ASNZS5149. Now at least two more safety measures should be implemented such as ventilation (natural or mechanical), safety shut-off valves, or a safety alarm.

What is Hybrid VRF?

Hybrid VRF is next generation technology from Mitsubishi Electric, the world leader in VRF Solutions. This unique 2-Pipe Heat Recovery VRF System replaces refrigerant with water between the Hybrid Branch Circuit Controller and the indoor units. This revolutionary design removes the need for expensive and on-going leak detection servicing and is specifically designed for occupied spaces where quiet, energy efficient, simultaneous heating and cooling is valued. Hybrid VRF provides a truly integrated solution for hotels, offices, hospitals and schools where occupant comfort is paramount.

The ETS and the Continually Rising Cost of Refrigerant

HVRF is not just about critical refrigeration limits. The cost of refrigerant, in particular R410A, is rising and has done so dramatically in the last 2 years with the introduction of the Synthetic Greenhouse Gas Levy which falls under the umbrella of the Emissions Trading Scheme (ETS). The New Zealand ETS puts a price on greenhouse gas emissions to provide an incentive to reduce emissions and in this case use alternative refrigerant gases that have less Global Warming Potential. The ETS has increased significantly with a rate increase (due January 1st 2019) to $41.55/kg of R410A contained in air conditioning units, and considerably more when purchasing additional refrigerant to charge a system. Prices have surged to as much as $100/kg in the New Zealand market.

The Following Projects All Benefited from Cost Saving on Refrigerant:

  • Rototuna Junior High School
    This project benefited from comfortable off-coil temperatures in the classroom and low noise, minimising classroom disturbance.
  • Rotorua Children’s Health Hub and Library
    The use of water instead of refrigerant through the indoor units provided quietness and comfort within the library.
  • Grafton Hall – The University of Auckland
    There was no need for leak detectors as there was no refrigerant in occupied spaces, saving on additional on-going maintenance costs.
  • Burnett Holdings
    With no refrigerant in occupied spaces, HVRF proved to be the perfect solution for individual small offices.
  • Boulcott Apartments
    The refrigerant restrictions in individual apartments also meant HVRF provided much quieter heating and cooling with low refrigerant cost for building owners.

Other Benefits of HVRF

  • HVRF is also a heat recovery system and provides high efficiencies.
  • HVRF is flexible and simple to design and install, incorporating the same control network and architecture as CITYmulti VRF.
  • The decentralised system means phased installation is possible with the same high levels of seasonal efficiency expected with VRF.
  • With water at the indoor units, HVRF provides comfortable and stable air temperature control; enhancing occupant comfort and making it an attractive option for many commercial applications.

New Service Tool Software for City Multi VRF Systems

Thursday 11th of April 2019
Mitsubishi Electric New Zealand is proud to release the recently updated Service Tool Software – Version 5.30 for checking, servicing and analysing City Multi VRF Systems.

As heating technology evolves, so too does the need for a monitoring system that not only gives you all the information you need in real-time, but is easy to use when you’re on (or away from) the job with limited time. Mitsubishi Electric New Zealand is proud to release the recently updated Service Tool Software for checking, servicing and analysing City Multi VRF Systems.

Evolving Data to Real-Time Visualisation

Moving from the older data table format, this newly updated version now features a new diagram format to help Service Technicians to more quickly quantify system performance and quickly identify any problem at a glance.

Easy System Monitoring at a Glance

The new City Multi VRF Service Tool condenses the entire system into a diagram, showing key components of each system for up-to-the-minute, simple monitoring in one place.

The diagram showing information related to a specific component is displayed next to it for quick referencing, so Service Technicians can easily see the value of any sensor, position of any valve or speed of any motor in its place on the refrigeration circuit in real-time, to accurately monitor the system and fix any issues that arise.

In the below example outdoor unit, we can easily see:

  • Compressor outlet temp = 96.6°C
  • Compressor crankcase temp = 41.8°C
  • Compressor speed = 72Hz
  • OU fan speed = 530rpm
  • OU coil refrigerant temp = 23°C in / 5 °C out

For an indoor unit we can easily see:
  • Fan speed = High
  • Mode called for = Heating
  • Refrigerant = 69.9°C in / 35.7°C out
  • Return air temp = 23°C
  • Valve position = 495 pulses open

Graphs Parameters Easily for Additional Reporting

The updated software now enables Service Technicians to graph any parameter being recorded to see a trend over time for accurate reporting and control. And, with the ability to graph multiple parameters against each other on the same time scale, comparative reporting is even easier.

For example, the graph below shows:

  • Compressor outlet temperature (TH4)
  • BC Box sub cooling outlet temperature (T5)

The Control is in Your Hands

With the newly updated Service Tool from Mitsubishi Electric, the servicing and maintenance of City Multi VRF Systems can be done at a glance with an easy-to-use, customisable online tool that not only saves time with reporting key data but will ideally save down-time onsite also.

The Next Generation Mitsubishi Electric PQRY Water Sourced VRF

Tuesday 22nd of January 2019
When an air cooled air conditioning solution isn’t practical, contractors and consultants often look for effective alternatives to power their systems that both reduces long-term expenditure and future-proofs their clients investment with a sustainable, environmentally-friendly air conditioning solution. With changes in regulations and the demand for environmentally-friendly solutions ever-growing, water is becoming a popular alternative within the HVAC industry.

The Next Generation in Water Sourced VRF

Introducing Mitsubishi Electric PQRY Water Sourced VRF Systems. These unique systems use water to offer a solution to a range of common challenges such as limited plant space, long refrigerant pipe runs and compliance to standards while retaining the advantages of VRF and the benefits from very high efficiencies.

City Multi PQRY units connect to a central (condenser) water loop and extract energy from this. That energy is then used for simultaneous heating & cooling in a similar fashion to a common air sourced VRF system.

Small Footprint, Big Benefits

Mitsubishi Electric Water Sourced units are specifically designed for commercial applications such as hotels, commercial buildings, office buildings, and so many more applications, either as new builds or retrofits. With a small footprint and the ability to reject energy to the building water loop instead of the air, water sourced VRF allows you to bring the outdoor units inside and reduce plant size when:

  • The outdoor plant space is limited
  • The buildings external outdoor aesthetics are critical
  • Pipe runs or pipe lifts are large

This flexibility means reduced costs, more usable space, no defrost cycle and the ability to bring the unit closer to the air conditioned zone, therefore reducing the additional refrigerant volume required (a dual benefit of lower refrigerant cost and improved compliance with NZS5149).

A Water Sourced System with the Benefits of VRF

Water sourced outdoor units are available in heat pump (heating or cooling) and simultaneous heating and cooling configurations with no change to the internal system design from our standard VRF, thus retaining VRF’s modular design style and removing the need for bespoke controls or valves as seen on chilled water systems. This makes Mitsubishi Electric PQRY an easy solution for end of life replacement jobs or when capital costs need to be spread out as the separately operating VRF systems allow for staged installs with the added benefit of much improved redundancy.

Utilising the wide operating water temperature range of 10-45°C, you can also reduce the size of the external heat rejection plant, take advantage of waste heat from server rooms, and connect to energy sources such as nearby rivers, lakes or a geothermal loop in order to reduce upfront costs and long-term energy usage.

Increased Efficiencies with Heat Recovery

Mitsubishi Electric PQRY features the same patented heat recovery technology at the indoor units as also found in Mitsubishi Electric 2-Pipe Air Sourced VRF units, which provides real world efficiency increases and running cost savings. With multiple water cooled systems, an additional heat recovery stage is obtained at the outdoor units through the buildings water loop. Often, PQRY full load COP’s without heat recovery will exceed 5.0 and can improve significantly further with double heat recovery.

Other Key Features of Mitsubishi Electric Water Sourced Systems

  • No requirement for ventilation around the unit, therefore offering installation cost savings
  • More efficiency by offering dual heat recovery at the outdoor and indoor units
  • Smaller footprints which offer improved plant space flexibility
  • Uses a modular, non-bespoke design making implementation easy
  • Is a 2-pipe system throughout the entire building with simultaneous heating and cooling which saves on installation costs compared to 4-pipe chiller or 3-pipe VRF systems
  • Includes improved redundancy as each system operates independently and allows for staged installs; spreading capital costs and reducing loads on existing chillers for replacement jobs.

If your client is looking for a total air conditioning system that is super energy efficient, has a small footprint, is sustainable and will reduce capital expenditure, Mitsubishi Electric PQRY Water Sourced VRF is the perfect solution to recommend for your next commercial project.

HYBRID VRF - Industry First Patented Technology

Tuesday 11th of December 2018
It is clear that designing building systems brings challenges. As we move to the future, inevitably there will be more regulations and legislation to adhere to, particularly around environment and occupant safety. BDT are no strangers to these challenges and we pride ourselves on providing solutions for the building market to comply, meet targets and provide outstanding quality systems for the end user.

BDT’s latest solution to the commercial building market is City Multi Hybrid VRF, the next generation of heat recovery systems for commercial buildings.

HVRF is a 2-pipe heat recovery system which replaces refrigerant with water between the BC Controller and the Indoot units, so there is no refrigerant in occupied spaces while providing higher efficiencies. You can also install and design it as a VRF whilst enjoying the features of a chiller system.

Why is this a great solution?

The SGG levy in New Zealand has put extra cost on purchasing synthetic greenhouse gases and this cost is set to increase, pushing up the price of refrigerants such as R410A. HVRF reduces this burden as it has less refrigerant in the total system. HVRF is ideal for applications where the limitation of refrigerant in occupied spaces is required, in particular where occupant safety is paramount. With no refrigerant in the occupied room space, this removes the need for expensive leak detection systems with ongoing maintenance costs.

HVRF is simple and flexible to design and install using the same control and network as VRF systems. Furthermore, the decentralised system means phased installation is possible with the same high levels of seasonal efficiency expected with VRF. With water at the indoor units, HVRF provides comfortable and stable air temperature control enhancing occupant comfort.

Introducing the E-Series Modular Chiller

Wednesday 28th of November 2018
It is Mitsubishi Electric’s most efficient chiller system yet! The E-Series Chiller by Mitsubishi Electric provides highly efficient performance thanks to its inverter compressors & DC fan technology. Available in either cooling only or heat pump, the E-Series comes in either 90kW, 150kW & 180kW modules with the ability to connect up to 6 modules reaching a maximum installed capacity of over 1MW.

It is an energy efficient alternative system with flexible design!

The highly efficient E-Series Modular Chiller Range, with an ESEER of 5.66, is designed to answer the need for controllable, energy efficient cooling and heating with reduced plant size and a host of advanced features and benefits taken straight from Mitsubishi Electric’s experience in the air conditioning industry.

The E-Series Modular Chiller is available in either a cooling only version or as a highly efficient heat pump model that uses two advanced DC inverter-driven scroll compressors in each 90kW module. Soft Start Technology means that the starting current is only 8 Amps per module, where a conventional style chiller would pull up to 180 Amps on start-up. This reduces mechanical and electrical stress improving equipment longevity.

Whether one module or six, the deliverable capacity range is between 8% to 100%. The E-Series Modular Chiller delivers market-leading levels of efficiency with the ability for units to operate on their own or in conjunction with others.


Sophisticated design and small footprint installation

The unique shape and modular design of the E-Series Modular Chiller means that the system can be constructed with up to six individual units connected together, to provide a total capacity between 90kW and 540kW. This also provides outstanding redundancy due to multiple refrigerant circuits.

The use of U-shaped high performance air heat exchangers offers a greater surface area, for higher heat exchange efficiency, this and the units are narrower than conventional systems. Each 90kW module can be positioned next to each other in a row, with up to six units using the same inbuilt, internal header. For larger systems, it is also possible to have double rows of the units with a gap of only 900mm service space plus it can be designed as a double-row double stack, offering space saving where plant area maybe limited.


And yes they are quiet too!

The E-Series Modular Chiller achieves low noise levels which is increasingly important in inner city locations. These low noise levels are achieved through both the unique construction and design of each unit, as well as the advanced component technology within each chiller.

BMS integration

The E-Series Modular Chiller is easily integrated with new and existing BMS systems, either hardwired or via MelcoBEMS Mini Interface it can be remotely controlled and monitored, ideal for facilities management.


New additions to the E-Series Chiller Family

As of September 2018, the Mitsubishi E-Series Range has been extended to now include 150kW & 180kW modules.

With similar technical features & providing excellent efficiencies, the P1500 & P1800 Models are a more traditional shape with vertical discharge condenser fans. Available in both cooling only & heat pump models, up to six of these modular chillers can be connected in one system.



Lossnay Fresh Air Energy Recovery Ventilation

Tuesday 6th of November 2018
Ventilation is an important aspect in any HVAC installation. It not only provides compliance to the G4 Clause of the New Zealand Building Code but also ensures internal environments are safe and suitable for occupation. With ever increasing energy costs and a push to lower carbon footprints, air to air heat recovery for ventilation is becoming a must have for any building.

Our current LGH-RVX-E Range of Fresh Air Energy Recovery Ventilation Systems have a treated, permeable paper energy recovery core. This core allows the transfer of heat and water vapour while preventing the transfer of gases.

So what sets the LGH Lossnay apart from other Ventilation Systems?


Total heat recovery
  • Energy recovery through the permeable core not only recovers sensible heat but also latent heat from humidity in the air, further reducing load on HVAC plant and saving on energy consumption.
Excellent energy recovery rates even in low temperatures
  • Lossnay’s total energy recovery rate is typically in the order of 70% ~ 75%. This is higher than common efficiencies seen for a solid core ventilator which transfers sensible heat only.
  • At 0°C outdoor air temperature, and a space temperature of 20°C, supply air from a Lossnay unit can be around 16°C – which is warm enough to supply directly to a fan coil unit without any expensive additional top up heating.
Optimised humidity management
  • Transferring latent heat (humidity) also helps maintain an acceptable relative humidity within the occupied space. With Lossnay, air introduced into the space is closer to the space humidity than other uncontrolled ventilators. Without Lossnay, air is typically preheated and humidified in Winter and precooled and dehumidified in Summer.
Standard Bypass Damper removing the need for additional controls
  • All LGH Lossnay units come standard with a Bypass Damper allowing for free cooling and night purge. Internal settings also prevent the unit from operating on bypass when supply air will be below an acceptable temperature.
  • Lossnay is able to communicate with Mitsubishi Electric Air Conditioning units allowing for the Bypass Damper to provide free cooling based on the connected indoor units mode of operation. This removes the need for any expensive additional controls.
Minimised riser space
  • Air processing locally removes the need for large roof mounted air handling units. Riser space can also be minimised by using smaller intakes closer to the space.
Reduced running cost
  • Lossnay removes issues associated with traditional methods of supplying untreated fresh air in summer and utilising electric heater banks for Winter. These old methods are no longer seen as acceptable as they commonly cause high running costs in Winter and problems such as poor cooling performance and condensate dripping from supply duct / grilles in Summer.
Very quiet operation
  • LGH Lossnay’s are quiet in operation with even the largest unit only producing 41dBA at 1.5m below the unit on high fan speed.
Air filtration
  • Outside and Exhaust Air Filters are provided as standard for core protection. An optional high efficiency filter can be fitted into the unit to filter the supply air to rating F7 (EU7).
Easy service access
  • Service accessibility is required to one side of the unit only. The electrical panel, core and filters can all be accessed through the one access panel.
Functional controls
  • PZ-61DR-E Wall Controller allows for the following additional functionality:
    - Display of outside air, exhaust air and calculated supply air temperature.
    - Function settings allow for fan speeds to be increased slightly to achieve airflow if slightly short.
Advanced Co2 Control and Air Pressure Control
  • Inbuilt logic allows CO2 control through input via a third party 0-10V CO2 Sensor.
  • Positive or negative pressure can be achieved by offsetting supply and exhaust fan speeds.
  • Test data for gas transmission shows this is very low - less than 3% for all gases tested.
  • Test data for bacterial transmission shows no bacteria is transferred between the exhaust and supply air streams.

AE200 Central Controller

Friday 14th of September 2018
Our current AE200, 10.4 inch touchscreen, is a popular central controller which is able to connect to all Mitsubishi Electric City Multi and split systems. The intuitive central controller allows you to control up to 200 indoor units as well as offering daily, weekly and 365 day timeclock control, plus offers remote accessibility through the client’s computer network.

This controller is able to offer a lot more functionality through additional hardware and licensing.

BACnet connection to a Building Management System (BMS) using licensing. This allows up to 200 indoor units to connect to a BMS through one BACnet license installed into the AE200 and subsequent expansion controllers without the need for expensive additional hardware.

Power Apportioning – The system utilises third party electrical pulse meters to measure the power usage of each outdoor unit via the PAC-YG60MCA-J PI controller. The power used is then assigned to each indoor unit based on the usage over that time. This can be used to assign power usage to individual units for on billing. This can now be achieved without the need for TG2000 software by exporting CSV data directly from the AE200 onto a USB which can be edited on a PC using the Charge Calculation Tool. The data can also be communicated to a BMS over BACnet using the BACnet license.

PI Controller – Third party electrical, water or gas pulse meters can be inputted into the system through our PAC-YG60MCA-J PI controller. This information can be displayed on screen or outputted to a CSV file on a USB enabling the end user to monitor building energy consumption.

AI Input Controller – Third party temperature and humidity sensors can be monitored using our PAC-YG63MCA-J and displayed on the AE200. Trending can be viewed over the AE200 web interface. An alarm output by email can be generated when measurement exceeds a preset upper or lower limit.

DIDO Controller – Control and Fault monitoring of external items can be achieved using our PAC-YG66DCA-J DIDO controller. This allows third party items to be time scheduled through the AE200 similar to an air conditioning unit or to be interlocked to any air conditioning unit connected to the AE200. This also allows indoor units to be turned on and off from an external input such as a security system.

Alpha2 PLC – The AE200 can connect to our Mitsubishi Electric PLC through our AHC adaptor. This allows for simple logic to be applied to third party digital or analogue inputs or sensor data of any air conditioning unit connected to the AE200. This logic can then be used to control digital or analogue outputs or any air conditioning unit connected to the AE200.

For more information on any of the above functionality please contact your local City Multi Sales Engineer.

City Multi VRF YNW

Monday 9th of July 2018
Mitsubishi Electric’s City Multi VRF YNW Range provides our lowest installation costs, running costs and CO2 emissions of a VRF system. This is achieved through the new 4-sided heat exchanger, compressor and fan design, improving both nominal and seasonal efficiency levels.

Launched at the City Multi Conference last year the VRF YNW Range offers further energy efficiencies with EP Models which retain the unique flat tube aluminium micro-channel heat exchanger, a pivotal step in providing more effective and efficient heat transfer.

YNW Range alleviates some of the legislative concerns (AS/NZS 5149:2106) regarding the critical concentration limit of refrigerant in occupied spaces, due to the significantly reduced refrigerant charge needed to produce the same rated output compared with previous models.

Advanced Heat Exchanger for Energy Efficiencies

The YNW Range uses a newly designed four-sided heat exchanger mounted on the upper-part of the module which decreases energy usage and increases the heat exchanger’s efficiency. The multiplier effect created by increasing the number of coil faces from three to four surfaces greatly improves the operational efficiency.

Superior Energy Efficiencies with EP Models

The YNW Range offers advanced heat exchangers on their standard models, incorporating copper tube aluminium fins; while high efficiency EP models incorporate the flat-tube aluminium heat exchanger, increasing the surface area of the coil for even higher efficiencies. The inside of the flat tube is divided into thin compartments which increase the area of contact between refrigerant and air, leading to a significant improvement in energy-saving performance.


Footprint Reduced by up to 29%!

YNW Range maximises the space available for plant by reducing the area required for outdoor units. Up to 51kW of cooling capacity can be delivered per square metre of plant thanks to the advanced wrap around the heat exchanger.

Greater flexibility for location of outdoor units is possible thanks to multiple external static pressure settings. Extending up to 80Pa will help with long or narrow ducting requirements.

Enhanced Inverter Scroll Compressor

Exclusive to the City Multi VRF YNW Range, the improved compressor with centrifugal force cancelling mechanism enables the speed to increase to 140 revolutions per second – speeding up start-up operation and offering improved part load performance.

These characteristics offer the most intelligent and reliable inverter scroll compressors on the market.

Advanced Compressor Programming

The YNW Range features adjustable logic settings such as Low Noise modes and compressor saturated suction temperatures including a variable floating SST.

The options offered by City Multi VRF systems allow fixed evaporation set points ranging from -6 all the way to 14 degree Celsius. By floating the saturated suction temperature, the condensing unit can lift the evaporation temperature as the fan coil units reach their temperature set point. The result, increased occupant comfort levels and further improvement on the overall efficiency of the units when looking at seasonal performance data.

Larger Capacity Range

The YNW Range not only offers a larger range of single module condensers, but also an increased number of twinned condenser options.

YNW Range is the largest range of condensers available in today’s market, allowing combinations up to 140kW for heat recovery systems and up to 168kW for the heat pump range in both the standard and high efficiency options.

The NorthMed Clinic is a new building situated at Auckland University of Technology’s (AUT) North Shore Campus. This innovative facility which opened in July 2017, comprises of modern medical offices and teaching space for Physiotherapy, Psychotherapy, Podiatry, Oral Health, and Student Health Services.

HYBRID VRF - Industry First Patented Technology

Thursday 9th of November 2017
It is clear that designing building systems brings challenges. As we move to the future, inevitably there will be more regulations and legislation to adhere to, particularly around environment and occupant safety. BDT are no strangers to these challenges and we pride ourselves on providing solutions for the building market to comply, meet targets and provide outstanding quality systems for the end user.

BDT’s latest solution to the commercial building market is Hybrid VRF, the next generation of heat recovery systems for commercial buildings.

HVRF is a 2-pipe heat recovery system, the difference is refrigerant is replaced with water from the BC Controller to the indoor units. You can install and design it as VRF whilst enjoying the features of a chiller system.

Why is this a great solution?

The SGG levy in New Zealand has put extra cost on purchasing synthetic greenhouse gases and this cost is set to increase, pushing up the price of refrigerants such as R410A. HVRF reduces this burden as it has less refrigerant in the total system.

HVRF is ideal for applications where the limitation of refrigerant in occupied spaces is required, in particular where occupant safety is paramount. With no refrigerant in the occupied room space, this removes the need for expensive leak detection systems with ongoing maintenance costs.

HVRF is simple and flexible to design and install using the same control and network as VRF systems. Furthermore, the de-centralised system means phased installation is possible with the same high levels of seasonal efficiency expected with VRF. With water at the indoor units, HVRF provides comfortable and stable air temperature control enhancing occupant comfort.

Modular, small footprint and low weight outdoors makes for manageable phased installation. HVRF is a fully packaged solution; valves, pumps and heat exchangers are all contained within the HBC Controller with minor third party items required, making commissioning simpler.

Ideal Applications:

  • Hotel
  • Office
  • Hospitals
  • Mixed-use buildings
  • Education

Introducing the New Range of Ultra-Quiet Ecodan Hot Water Heat Pumps

Friday 15th of May 2020
Everyone knows how distracting a loud humming indoor unit can be. So in our industry, we commonly refer to how noisy a heat pump is based on the indoor unit sound levels. However, what is often overlooked is the sound level of the outdoor unit. Housing the compressor, it has the potential to create a significant level of unwanted noise.

High-density housing and noise levels

Mitsubishi Electric has always been at the forefront of improving technology including sound levels, to meet the ever-changing need of consumers. So it should come as no surprise that with the rapidly changing urban landscape to more high-density housing, Mitsubishi Electric has now specifically tackled outdoor sound levels.

Three times quieter than previous models

Ecodan has always been one of the quietest hot water heat pumps on the market. And with the introduction of the new ultra-quiet Ecodan Range, it has taken hot water heat pumps to the next level. These new models offer superb style, market-leading energy efficiency and sound levels. Designed especially for residential applications, the 6.0kW, 8.5kW and 11.2kW units are 3dBA quieter than previous models.




Flexibility with outdoor unit placement to keep neighbours happy

With higher density housing becoming more common in New Zealand, quiet outdoor operation is important especially if you want to keep your neighbours happy.

The new Ecodan Range features an industry-leading sound pressure level of 45dBA*, measured at a distance of 1m.

As a result, the system offers greater placement flexibility as the outdoor unit can now be located much closer to property boundaries. This makes the Ecodan Hot Water System ideal for areas sensitive to outdoor noise without disturbing the neighbours.

Our market-leading Ecodan Hot Water Heat Pump solutions are designed to provide a home with ultra-quiet, hot water heating and space heating with year-round energy efficiency and reliability.

Introducing Replacement and Pipe Reuse Technology

Tuesday 10th of September 2019
As part of its Core Environmental Policy and commitment to the restoration of the global environment, the Mitsubishi Electric new R32 line-up now features Pipe Reuse Technology.
This unique technology allows for the replacement of old, inefficient R22 systems (which are now phased out) with new, low-GWP R32 heat pump systems without having to replace the existing pipework of the old system but rather, reuse the pipework and wiring to make way for the new R32 system.

The New Power Multi Series – PUMY-SP

Tuesday 13th of August 2019
An exciting new addition has been made to the Multi Room lineup with the new single fan PUMY-SP. Replacing the MXZ-8C140/160 Power Multi units, this system now offers an easier installation, a wider range of installation possibilities, improved energy efficiency and an unobtrusive, compact size.

Simple and Discrete Design

The single fan unit offers a low height profile and small footprint, keeping outdoor spaces uncluttered. The compact design fits into narrow outdoor areas found in applications like condominiums and offices. And with a light weight, transportation and installation is easy.

Energy Saving with High COP

The Power Multi Series provides superior energy efficiency with a high COP of over 4, so you get over 4kW of heat energy output for every 1kW of power input.

Flexible Installation Possibilities

With an external static pressure of 30Pa, the PUMY-SP can be installed in a wider range of locations such as on balconies in high-rise buildings or spaces near louvers. The compact size also allows installation in locations that would otherwise be unsuitable. Piping workability is greatly improved with piping pullout locations in four directions, providing expanded piping layout flexibility.

Guaranteed Heating Down to -20°C

The Power Multi Series is able to provide heating right down to -20°C outdoor temperature, so you stay warm on even the coldest days.

Super Silent Mode

The noise level of the unit can be reduced by up to 10dBA, allowing the unit to operate during the night in a residential zone without disruption to your neighbours.






Potable Hot Water Solutions

Monday 12th of August 2019
Potable hot water heating in the commercial and residential sectors can be a large part of a buildings electricity demand. So, it makes sense that only the best solutions to heat this water as efficiently as possible are considered in any new builds or retrofits.

At Mitsubishi Electric, this need has been a driver for the inclusion of PWFY-BU modules in our Range of City Multi R2 Heat Recovery Systems which recovers heat rejected from your office space, and transfers this into your potable hot water cylinder. This technology incorporates a 12.5kW water module that connects to your R2 System via the Branch Controller, and is capable of providing 70°C hot water via the cascade-based R134a secondary refrigerant system in the water module.

This technology has been used in residential properties, medical facilities, veterinary services and hotels / motels across the country.

However, as the building stock in New Zealand can be quite diverse and water usage patterns vary immensely, there is a need to offer a broad range of potable hot water options to suit the needs of the market.

Case Study – Mt Ruapehu Ski Club

Tuesday 12th of February 2019
When Ruapehu Ski Club was looking to replace hot water facilities in one of their buildings called ‘The Lodge’ on Mount Ruapehu, the club wanted to find a modern, efficient way to provide these important creature comforts for their club members

A major part of RSC’s aim when doing this refurbishment was to reduce the peak load of electricity used during the ski season. They required a hot water heating system that would work in the cold climate and still produce hot water efficiently.

The club building is able to house up to 70 people as well as leisure, cooking, wash facilities and ski workshop facilities.

The Challenge

Five existing hot water cylinders which used direct electric elements providing 900 litres of potable hot water needed to be replaced, alongside the heater in the drying room which consisted of a fan blowing over a 6kW heating element.

The Hot Water Solution

The installation consisted of two 11.2kW Ecodan Hot Water Heat Pump Hydrobox Systems and two 600L Hot Water Storage Cylinders. The outdoor units incorporate the Mitsubishi Electric patented Zubadan Flash Injection Technology which means they are able to maintain their full 11.2kW capacity with 55°C hot water output down to an ambient temperature of -15°C; suitable for the alpine conditions at Mt Ruapehu.

The Ecodan Hydrobox contains hydraulic components, pump, expansion vessel, flow sensor and a refrigerant to water heat exchanger, making it simple to connect just water piping to the cylinders. The two 600L Cylinders contain 40m coils to maximise the heat exchange inside the cylinder. Three temperature sensors are mounted in each cylinder to monitor the tank temperature from top to bottom.

Modulating control valves have been installed to balance the hot water provided by each of the two independent systems, allowing for automatic isolation of each cylinder if temperature cannot be maintained. Electric immersion elements are also installed in the hot water cylinders. These are controlled by the Building Management System to provide additional heating capacity if required during periods of high hot water consumption and to provide legionella prevention at scheduled intervals. The elements also serve as a backup heat source if the Ecodan Systems are shut down for maintenance. The club can reduce peak electricity consumption using the integrated FTC5 Controllers scheduling function so that hot water recovery times are outside of kitchen operating hours.

As the drying room is in continuous use during the ski season, an inverter driven 3.5kW HyperCore High Wall Heat Pump provides ample heat and is also controlled remotely depending on occupancy, further improving efficiency in place of the 6kW fan blown heater.

The BMS Solution

BDT provided a Building Management System to monitor and control the domestic hot water and space heating systems in the lodge. The controls package consisted of a web-enabled Black Diamond Controls Central Controller, BACnet Controller and three MelcoBEMS Mini’s to provide Modbus interfaces to the Mitsubishi Electric Ecodan and HyperCore Systems.

In addition, the site energy consumption is monitored via a newly installed Modbus Energy Meter connected to the main incoming supply. This allows the club to monitor their year-on-year energy savings and real time consumption.

Due to the remote nature of the site, the control system was developed to provide redundancy and automated email paging in the event of faults or persistent low hot water temperature situations.

The BMS provides a web interface which allows specific club member access to remotely monitor and adjust operating parameters such as temperature set point and time schedules, via a secure connection.

This system has seen its first season on the mountain, having successfully delivered hot water to Ruapehu Ski Club and we will continue to monitor the system year on year.



Ecodan Smart Energy Monitoring and Management

Monday 14th of January 2019
State of the art energy monitoring and management of the Ecodan Heat Pump System means families now have the visibility and freedom to efficiently manage their overall household power consumption for heating and hot water. Energy monitoring and control ensures households can take advantage of off-peak tariffs or improve the use of solar panels, providing them the ability to save even more on their power bill.

End-users can now easily check the energy data of the Ecodan Heat Pump with the ability to view electricity consumption and heat output on the remote controller.

Data Shown on the Remote Controller

  • Consumed electrical energy for space heating, cooling and domestic hot water (kWh)
  • Delivered energy for space heating, cooling and domestic hot water (kWh)

Other Features
  • Daily, monthly and yearly data are stored and can be displayed using the main remote controller
  • External power meter and heat meter can be connected for accurate measurement
  • An SD card is included for storing usage data

Auto Adaptation

Our advanced Auto Adaptation Function measures the room temperature and outdoor temperature, calculating the required heating capacity for the room.

The flow temperature is automatically controlled according to the required heating capacity, while the optimal room temperature is maintained at all times; ensuring the appropriate heating capacity and preventing energy wastage.

Future Room Temperature Estimation

By estimating future changes in room temperature, the system works to prevent unnecessary increases and decreases in the flow temperature. Auto Adaptation maximises both comfort and energy savings.

2-ZONE CONTROL

Using Ecodan, it is possible to control two different flow temperatures, thereby managing two different heating load requirements. The system can adjust and maintain two flow temperatures when different temperatures are required for different rooms; for example, controlling a flow temperature of 45°C for the bedroom radiators and another flow temperature of 35°C for the living room underfloor heating.

Ecodan – Why Water?

Monday 17th of December 2018
The exact origin of using water for heating has some debate, but it dates back to around the 13th century where monks diverted river water and heated it in furnaces to warm their monasteries. With warm buildings in the cold months, the benefits of this ingenuity were obvious and over the years inventors and engineers have gradually found ways to improve on the concept. Following the industrial revolution, Charles Hood wrote the first engineering handbook for hot water heating in 1837, which was published in revised editions for 50 years.

Why Water?

Hydronic heating systems are commonly used throughout Europe and other parts of the world. In fact today, over two thirds of the world use warm water central heating.

So why is water such a good option to use?

  • Water is abundantly available, non-toxic and non-hazardous.
  • Water can retain heat longer than most other substances.
  • It has a unique heat capacity; the presence of hydrogen bonds causes water to heat and cool slower than other substances.

The Benefits of Water

If you remember back to school science class, water has a very high “specific heat capacity”. What this means for us is once the water is up to the desired temperature in our heating circuit, the water holds its heat energy well. Therefore it is a good substance to use to distribute heat.

The benefits of using heating circuits are:

  • Comfort levels are high because the whole house is heated.
  • There is no fan blown air so circulation of allergens and dust are reduced.
  • Condensation is minimised.

What About Efficiency?

The ideal temperature to run underfloor heating is ideally somewhere between 35°C and 40°C (radiator temperatures vary according to the output capacity of the radiator). This makes using hot water heat pumps ideal for supplying heat to the emitter.

When using gas or oil boilers the temperature of the water coming out of these systems is too hot for underfloor heating. As a result the water needs to be blended down in temperature to mitigate the risk of overheating the house or even damaging the floor. Aside from this, the carbon emissions of these types of heating by comparison to a heat pump is significantly higher. Gas has over 5 times the emissions and oil boilers have over 8 times the emissions of heat pumps.* This is thanks in part to the clean electricity provided to us in New Zealand by the hydroelectric stations and in part to the high efficiency of the Ecodan Air to Water Heat Pumps.

When choosing central heating, Ecodan is unrivalled for performance, efficiency and carbon emissions.

*Based on New Zealand electricity grid emission factors for 2015 (MBIE) and using average COP values for Ecodan Air to Water Heat Pump based on BSEN14511 testing.

The Concept

In the commercial arena using water is commonplace because these efficiencies have a direct implication on budgets, as building owners take in to account running costs as a part of their budget forecast. If running costs, efficiency and being eco-friendly is so important to those building large buildings, how much more important should it be to homeowners running their own homes?

When clients who design or install commercial heating systems hear about these systems they can immediately see the benefit and understand the concept as this applied engineering used in the commercial world directly translates into what we are doing domestically.

Why Ecodan?

The Ecodan Range by Mitsubishi Electric is unrivalled for performance, efficiency and quietness. Crucially with hot water heat pumps you want the heat pump to deliver all the heat you need without backup or supplementary heat sources.

With New Zealand being an unregulated market place for this technology, there are a number of manufacturers with systems which are designed for warmer climates, and have particularly poor performance in colder weather and therefore rely on inefficient back up as the norm. With Ecodan you can be assured that the performance delivered via our Power Inverter and Zubadan Systems will work throughout all New Zealand conditions.**

** All units are rated at 2°C ambient, Zubadan units hold full capacity and 55°C output water down to -15°C.

The Future

As the need to be more energy efficient becomes a higher priority to us, we will see that air to water heat pump systems are the future of home heating, and remember the Ecodan System can also generate all your domestic hot water too. If your client likes the idea of a hydronic heating system, Ecodan is the energy efficient answer.









Ecodan Central Heating and Hot Water

Wednesday 21st of November 2018
In New Zealand central heating is fast becoming the heating system of choice where whole home comfort is highly desirable. Whether it is underfloor heating, or radiators as used throughout Europe, both are becoming increasingly popular in the domestic market. So, the question must be asked, what is the best way to generate heat? Also, what factors are important to consider when choosing a central heating system for your client?

Consider how much energy your house uses and what the best ways might be to reduce this energy consumption

This is a big subject to cover, and addressing it means that we will have to challenge the way things have always been done by giving detailed attention to areas we often overlook.

These areas include the effects of the day to day weather on a home and if the insulation levels of the home mean that the energy use is higher than necessary.

Among other factors such as location and orientation, good thermal insulation reduces the effect of the surrounding weather on a home. By keeping it cooler in summer and warmer in winter, the need for cooling and heating is reduced.

Consider what the highest consumers of energy are in your home

Current statistics show that the highest consumers of energy in New Zealand homes are hot water (38%) and home heating (36%) which combined account for 74% of your energy use.

Finding the most efficient way to generate your hot water and heating therefore is an important point of consideration.

The Ecodan Range of air to water heat pumps are designed to deliver efficient, renewable heating and hot water for your home. Mitsubishi Electric are once again leading the way with the acclaimed Ecodan Range, bringing intelligent, high quality whole home heating to New Zealand.

Coefficient Of Performance

Within the industry for air to water heat pumps there is some choice on the market however the performance of the units can vary significantly. A commonly used measure is the Coefficient Of Performance (COP) which is simply the amount of electrical energy consumed compared to the system heat output. A heat source that is classed as renewable is a product that outputs at least 2.5 times the energy consumed.

For example, a COP of 1 : 2.5. A COP is a specific measure on a given day. So, if the outdoor ambient temperature is 15°C and the heat pump is putting a flow temperature of 35°C, it stands to reason that the COP on that day and time would read very differently to say an ambient temperature of 2°C and a flow temperature of 55°C. In this case the heat pump will need to work harder to pull heat from a colder ambient temperature and maintain a higher output.

Seasonal Coefficient Of Performance

What would be more accurate is a measure that rates the system seasonal performance known as Seasonal Coefficient Of Performance (SCOP), where the system is measured against year round outdoor ambient temperatures.

However, these figures can be hard to find, so how then can you make an educated choice for a system that will meet your client's needs? I would suggest that if manufacturers indicate that their systems are not suitable for colder areas of the country, or if they are reluctant to publish performance at low temperatures, then this is a good indication that their systems perform poorly in colder temperatures.

This means a back up immersion heater will have to be used, compromising system efficiency and therefore increasing environmental impact and run costs.

Simply put – not all heat pumps are the same. In some cases, the performance can be so poor that you would save your client's capital expenditure and run costs if you installed a gas central heating system.

The Mitsubishi Electric Solution

With a range of integrated products, Mitsubishi Electric will be bringing central heating and hot water solutions to our lineup. Our hot water cylinders are high quality products – pre-plumbed, pre-wired, low standing loss and using plate heat exchangers for high efficiency hot water generation.

The flow temperature controllers are the Fifth Generation (FTC5) Controllers, with unique self-learning settings for maximum efficiency, control and feedback with energy monitoring built in. All of course tied off with a single outdoor unit with the usual high efficiency and low noise you would expect from a Mitsubishi Electric unit.

Zubadan

New Generation Zubadan provides powerful heating in cold regions where most heat pumps lack in performance. Zubadan's rated heating capacity is maintained even in outdoor temperatures as low as -15°C, with guaranteed heating operation at -25°C outdoor temperature. That means Zubadan can be trusted to provide comfortable heating during severe winter months. Furthermore, faster tank heater times are achieved in low ambient temperatures compared to standard models temperature. Zubadan is available on our 8kW – 14kW models only.

Smart Energy Monitoring

State of the art energy monitoring and management of the Ecodan Heat Pump System means families now have the visibility and freedom to efficiently manage their overall household power consumption for heating and hot water. Energy monitoring means households can now easily take advantage of off-peak tariffs, giving them the ability to save even more on their power bill.

And it’s easy to use! Once the app is installed on your device, simply stick the target on the wall, aim your device and start the selection process!

The ultimate in energy efficient home heating has arrived!

Friday 6th of March 2015
Introducing the Mitsubishi Electric Deluxe FH High Wall Heat Pump Series. All models have been awarded the coveted Energy Star® mark and packed with advanced features, the range ensures unparalleled energy efficiency as well as customised comfort year round for you and your family.

Exclusive to the Deluxe FH Series, the unique 3D i-See Sensor detects the exact position of you and your family based on individual heat signatures and provides the perfect amount of heating or cooling. The 3D i-See Sensor also acts as an advanced occupancy sensor. After a set period of time with no one in the room, the heat pump automatically switches to energy saving operation, leading to a reduction in energy usage by up to 10%! Do you prefer to feel the heat directly but your partner does not? Simple! A breakthrough in comfort, the unique split vane design means direct and indirect air flow modes can be customised to suit both of you at the same time! This is achieved as the vanes can independently direct air upwards, downwards or to the side. This feature also makes the Deluxe FH Series perfect for heating and cooling multi-level hallways in homes. For the ultimate in home heating, you must consider the HyperCore FH Series. Not only does this range boast the ultimate in energy efficiency and customised comfort, but with the addition of HyperCore® Technology you can rest easy knowing you and your family will be toasty warm during even the coldest days and nights. While most heat pumps produce less heat below 7°C, HyperCore® guarantees full rated heating capacity right down to -15°C and even heats down to -25°C. The Mitsubishi Electric HyperCore® Range is the only heat pump that can guarantee this level of advanced performance.

In loving memory of Ken Lilley

Wednesday 3rd of April 2013
The Black Diamond Technologies team is shocked and deeply saddened by the loss of Ken Lilley. Ken was killed in a motorbike accident Tuesday 2nd April 2013 while travelling from his holiday home in Kaiteriteri. Ken has been a key part of BDT and all of our lives for so long; his loss has left us grieving terribly. Our hearts go out to Maria, Vanessa and Jordan and the rest of Ken’s family. Ken has been part of the BDT family since 1986, starting his early career as a South Island sales representative. Ken quickly rose to National Sales Manager before being offered a share-holding and directorship. Ken led BDT as Managing Director since 2002. Ken was well respected across the retail and air conditioning industries for his charismatic approach, business knowledge and marketing expertise. During Ken’s career he successfully marketed and distributed a number of brands, most well-known being Mitsubishi Electric and Black Diamond. Within BDT, his personal, family approach will be missed greatly by all staff. We have lost a captivating, innovative and creative leader. He was inspiring and always had a smile and a joke for everyone, while leading our company to success after success for decades. He leaves behind a strong organisation that will be a fitting legacy. Those wishing to pass on their condolences can do so through BDT. Messages can be left at ken.bdt.co.nz . Kind Regards, Ron Woodrow Chairman & Founder Black Diamond Technologies Ltd

Mitsubishi Electric sponsors new TV show "The Block NZ"

Thursday 5th of July 2012
As far as hot topics go, the upcoming renovation-reality series The Block NZ appears to have captured the nation’s attention already. It is little wonder as Kiwis have always taken pride in renovating their own homes. As a nation of 4.4 million DIY experts we have mastered combining kiwi ingenuity with leading interior design in our apartments, homes and bachs. The Block NZ debuts here early July on the back of almost a decade of success in Australia, where the show ranks as the highest rated television series of all time. This is not to mention the international success the show has encountered with 350 episodes being produced worldwide! The Block NZ will see four couples - siblings, spouses, best friends - compete to renovate four run-down houses in a very upmarket suburb. Room by room, week by week, they'll fix up the homes to sell at auction for the highest price - and they have to live in the houses while they do it. That means no kitchen, no bathroom, not even a clean place to sleep until that room is renovated! With some contestants leaving their jobs to take up this once-in-a-lifetime opportunity, it is no secret that there is a lot at stake. It all comes down to the auction, which will be broadcast LIVE. All four couples will receive profits from the sale of their house on the night, and the winner will take home an additional cash prize of $80,000. Mitsubishi Electric is proud to be a sponsor of The Block NZ, providing the contestants with products that will improve their homes and complement their designs. Heating, ventilation and insulation solutions are recognised as ways to provide tangible increases in a home’s value. So too is the importance of selecting energy efficient products to contribute to lower ongoing home running costs. And with products ranging from heat pumps to ventilation to refrigeration, Mitsubishi Electric should unquestionably be top of mind when NZers embark on a renovation project. Don’t miss the renovation drama! The Block will air on TV3 Wednesday and Thursdays at 7.30pm from 4 July 2012.

Thursday 10th of June 2010
If you want efficient and effective home heating, Mitsubishi Electric Heat Pumps have a distinct advantage. Why?
