Industrial chillers are a type of chillers, and chillers can be classified into air-cooled chillers and water-cooled chillers. The chiller is a water-cooling device that is capable of providing constant temperature, constant current, and constant pressure cooling equipment. The principle of the chiller is to inject a certain amount of water into the machine's internal water tank, and the water is cooled by the chiller refrigeration system. The water pump inside the machine then injects the low-temperature frozen water into the equipment to be cooled. The chilled water will be inside the machine. The heat is carried away, and the high-temperature hot water is returned to the water tank again for cooling. In this way, the cooling is exchanged and cooled to achieve cooling of the equipment.
