Air conditioning water machines, also known as water-cooled air conditioning systems or water-cooled cold and hot air systems, are air conditioning equipment that uses water as the heat energy carrier. Unlike fluorine systems that directly use refrigerants for heat exchange, air conditioning water machines first cool or heat through the refrigerant in the internal circulation system, and then transfer this cold and hot energy to the end users, such as various rooms in the building, through water as the medium.

The working principle of the air conditioning water machine is mainly based on the vapor compression refrigeration cycle. The specific steps are as follows:

Compression process: The compressor compresses the low-temperature and low-pressure refrigerant gas from the evaporator into high-temperature and high-pressure gas.

Condensation process: The high-temperature and high-pressure refrigerant gas enters the condenser, where it exchanges heat with cooling water or air. After releasing heat, it turns into a high-pressure liquid.
