Schematic Diagram of Free Match Series Inverter Heat Pump Multi VRF System
The outdoor and indoor units start to work once the power is switched on. During the cooling operation, the low
temperature, low pressure refrigerant gas from the heat exchanger of each indoor unit gets together and then is taken into
the compressor to be compressed into high temperature, high pressure gas, which will soon go to the heat exchanger of
the outdoor unit to exchange heat with the outdoor air and then is turned into refrigerant liquid. After passing through the
throttling device, the temperature and pressure of the refrigerant liquid will further decrease and then go the main valve.
After that, it will be divided and go to the heat exchanger of each indoor unit to exchange heat with the air which needs
to be conditioned. Consequently, the refrigerant liquid become low temperature, low pressure refrigerant gas again. Such
a refrigeration cycle goes round and round to achieve the desired refrigeration purpose. During the heating operation, the
four-way valve is involved to make the refrigeration cycle run reversely. The refrigerant radiates heat in the heat exchanger
of the indoor unit (so do the electric heating devices) and absorb heat in the heat exchanger of the outdoor unit for a heat
pump heating cycle so as to achieve the desired heating purpose.
