Schematic Diagram of Free Match Series Inverter Heat Pump System
The outdoor and indoor units start to work once the power is switched on. During the cooling operation,
t
he 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
r
efrigerant 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.
