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

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

the heating operation, the four-way valve is involved to make the refrigeration cycle run reversely. The refrigerant
