Industrial water chiller is a kind of water cooling equipment that can provide constant temperature, constant current and constant pressure. The principle of the chiller is to inject a certain amount of water into the internal water tank of the machine, and the water is cooled by the refrigeration system. Afterwards, the water pump inside the chiller injects cryogenically frozen water into the equipment that needs to be cooled. The chilled water takes away the heat inside the machine and returns the high-temperature hot water to the water tank for cooling. In this way, the circulation exchange cooling can achieve the function of cooling the equipment.
