The water-cooled central air conditioner consists of four major components, a compressor, a condenser, a throttling device, and an evaporator. The refrigerant is circulated in the above four major components in sequence, and the refrigerant (refrigerant) from the compressor is heated and passed through the condenser. The temperature is reduced and the pressure is reduced, and the condenser takes the heat to the cooling tower through the cooling water system, and the refrigerant continues to flow through the throttling device to form a low-temperature and low-pressure liquid, flows through the evaporator, absorbs heat, and is compressed. A chilled water circulation system is connected to both ends of the evaporator, and the refrigerant absorbs the heat to lower the temperature of the chilled water, so that the low-temperature water flows to the user end, and then exchanges heat through the machine coil to blow out the cold air.
