The refrigerant will evaporate at low temperature and low pressure to produce a cooling effect; it will condense at normal temperature and high pressure and release heat to the surrounding environment or cooling medium. The steam becomes high-pressure liquid after condensing at normal temperature and high pressure, and its pressure needs to be reduced to the evaporation pressure before it can enter the container.
The liquid vaporization refrigeration cycle is composed of the four processes of working fluid vaporization, steam boosting, high-pressure vapor condensation, and high-pressure liquid depressurization. The low-pressure gas sucked by the compressor is compressed into high-temperature and high-pressure gas through the compressor, and the high-temperature gas passes through the heat exchanger to reduce the water temperature. At the same time, the high temperature gas will condense and become liquid. The liquid enters the evaporator to evaporate. (The evaporator also has a heat exchange medium while evaporating. The model and structure of different machines are different according to the heat exchange medium. Commonly used are air cooling and ground source.) The liquid changes after passing through the evaporator. The low-temperature gas is sucked in by the compressor to be compressed again, and the circulating water on the side of the wall-mounted split air conditioner becomes hot water of about 45-55 degrees. The hot water is sent to the room that needs heating through the pipeline, and the room is equipped with a fan coil to exchange the hot water and air for heating purposes.
