Evaporator Cross flow fan

Condenser

Gas liquid
separator Compressor

When the power is on, indoor and outdoor units will start to run. The compressor sucks low-pressure refrigerant gas from
the evaporator of indoor unit and then discharges high-temperature, high-pressure refrigerant gas into outdoor
condenser. Then air exchanges the heat with outdoor air and becomes refrigerant liquid. The liquid is throttled by the
capillary and changes into low-temperature and low-pressure liquid and then flows into indoor evaporator. Then liquid
exchanges the heat with the required air and changes into low-temperature and low-pressure refrigerant gas. The cycle
introduced above goes on and on, and the demanded low temperature environment is maintained

Separator Compressor

When the power is on, indoor and outdoor units will start to run. When the system operates in cool mode, the
compressor sucks low-temperature, low-pressure refrigerant gas from indoor evaporator and then discharges
high-temperature, high-pressure refrigerant gas into outdoor heat exchanger. With the help of axial flow fan, the gas
transfers its latent heat into outdoor air and becomes high-pressure refrigerant liquid. The liquid is throttled by the
capillary and changes into low-temperature and low-pressure liquid and then flows into indoor heat exchanger. With the
help of centrifugal fan, the liquid evaporates into low-temperature refrigerant gas and indoor air is cooled down. The
refrigerant gas is sucked into the compressor and the cycle introduced above goes on and on, and the demanded low
temperature environment is maintained. When the system operates in heat mode, four-way valve changes its way and
the refrigerant flows into the reversible cycle as the cool mode. The refrigerant discharges its latent heat in the indoor
heat exchanger, and sucks heat from outdoor heat exchanger and forms the heat pump cycle. This cycle goes on and on,
and the demanded high temperature environment is maintained.
