 Low Running Cost
Linear Inverter Provides Optimal Capacity Control
Inverter Control Reduces Capacity Requirements
Outdoor unit capacity can be smaller than total indoor unit capacity when indoor units have varying peak times.
Maintains comfort condition at lower cost.
An inverter is used to control capacity in response to the air conditioning road, which changes constantly over time and according to the zone involved. This enables the units to deliver superior performance in terms of both comfort and running costs. Moreover, Mitsubishi Electric has developed an original single inverter compressor which helps to save energy by eliminating the switching loss that occurs when multiple compressors are used. The linear inverter thus provides just the right solutions for meeting the requirements of diverse load variations.
Inverter Controlled Compressor
Optimized control of compressor frequencies in relation to the cooling-heating load results in minimal energy costs.
Individual Control
The CITY MULTI series includes both outdoor units with enhanced capacity control by inverter and indoor units with individual operation on a room-by-room or area basis. Selective air conditioning in only the rooms or areas where it is needed maximizes the cost savings.
Simultaneous Heating / Cooling (Heat Recovery System) Brings Energy Savings
With the same refrigerant circuit, waste heat generated in the cooling mode is recovered for heating operation. When in the heating mode, thermodynamic transfers are made to cooling operations. The result is highly efficient energy saving. The waste heat recovery system in the refrigerant system increases savings the more heating and cooling are used simultaneously.
Heat recovery through the water system is also possible in addition to that provided by the refrigerant system in the WR2 water cooled system.
