Industrial chiller coolers play a very important role in industry. It is suitable for refrigeration processes in electroplating, chemical, printing, pharmaceutical, plastics and other industries. Since water coolers are widely used, let us look at the three main circulation systems of industrial coolers.
Industrial chillers are not only used in plastics, electronic refrigeration, medical equipment, leather processing and other fields, but also in daily air conditioning and refrigeration activities. The chiller is composed of refrigerant circulation system, water circulation system and electrical automatic control system.

1. Refrigerant circulation system Liquid refrigerant exists in the evaporator of industrial water cooler. The refrigerant evaporates after absorbing heat from the water, and finally there is a temperature difference between the water and the refrigerant. The liquid cooler becomes gaseous after completely evaporated. After the gas refrigerant is absorbed by the compressor, it dissipates through the condenser, the temperature drops, and a liquid is formed, and the refrigeration cycle is finally completed.

2. Industrial water chiller water circulation system The main function of the water pump is to pump the water in the water tank to the cooling device. The water will be heated to increase the temperature and then returned to the refrigerator.

3. Electrical automatic control system The utility model includes an automatic control part and a power supply part of an industrial water cooler system. The automatic control part includes relays, pressure protection, temperature controller, delay device, overload protection, etc., which can automatically start or stop according to the water temperature. After the power passes through the contactor, it is supplied to the compressor, water pump and fan lamp.
