Schematic Diagram of Multisplit Inverter Heat Pump
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.
