When the air conditioner is in refrigeration operation, low-temperature and low-pressure refrigerant gas is sucked in by the compressor and pressurized to become high-temperature and high-pressure refrigerant gas. The high-temperature and high-pressure refrigerant gas releases heat in the outdoor heat exchanger (condensed through the condenser) and becomes a medium temperature and high-pressure liquid (heat is taken away by the outdoor circulating air). The medium temperature and high-pressure liquid is then throttled and depressurized by the throttling component to become a low-temperature and low-pressure liquid, Low temperature and low pressure liquid refrigerant absorbs heat and evaporates in an indoor heat exchanger, becoming a medium to high temperature and low pressure gas (indoor air is cooled and cooled by the surface of the heat exchanger to achieve the purpose of reducing indoor temperature). The low temperature and low pressure refrigerant gas is then sucked in by the compressor, thus circulating
