SYSTEM DIAGRAM
When the power is on, the unit start to work. The compressor sucks low-pressure
refrigerant gas from the evaporator and discharges high-temperature and high-pressure
gas into condenser. Then air exchanges the heat with outdoor air and becomes
refrigerant liquid. The liquid is throttled by the capillary and changes into low-pressure
liquid and low-pressure liquid and then flows into indoor evaporator. The liquid
exchanges the heat 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.

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 refrigerant gas from the
evaporator an sucked by compressor, compressor into high-temperature, high-pressure
Gas, and then discharges into condenser, heat exchanges with the outdoor air becomes into
refrigerant liquid, the liquid is throttled by the capillary and the temperature and
pressure lower down, enter into the evaporator, heat exchanges with the indoor air which
need to be adjusted, then changes into low-temperature, low-pressure refrigerant gas, the
cycle introduced above goes on and on, the demanded low temperature environment is
maintained. (when in heat mode, the 4way valve changes its way and the refrigerant flows
in the reversible cycle, to make the condenser sucks heat, evaporator discharges heat, and
the demanded high temperature environment is maintained.
