Comprehensive Interpretation: Three Circulatory Systems of Industrial Chillers

Industrial chillers have three circulatory systems, one is a refrigerant circulatory system, one is a water circulatory system, and an electrical control system. These three circulatory systems are indispensable.

The operation of the industrial chiller system is through three interconnected systems: the refrigerant circulation system, the water circulation system, and the electrical automatic control system.

The refrigerant circulation system of the industrial chiller is that the liquid refrigerant in the evaporator absorbs heat in the water and begins to evaporate. Finally, a certain temperature difference is formed between the refrigerant and the water. The liquid refrigerant also completely evaporates into a gas, and is compressed afterwards. The machine sucks in and compresses (the pressure and temperature increase), and the gaseous refrigerant absorbs heat through the condenser (air-cooled/water-cooled) and condenses into a liquid. After throttling through the expansion valve (or capillary tube), the refrigerant turns into a low-temperature and low-pressure refrigerant and enters the evaporator to complete the refrigerant circulation process.

The water circulation system is a water pump that is responsible for pumping water from the tank to the equipment that the user needs to cool. The chilled water brings the heat away and the temperature rises and returns to the chilled water tank.

The electrical automatic control system includes a local and automatic control part of the power supply.

Part of the power supply is through a contactor and supplies power to compressors, fans, pumps, etc. The automatic control part includes the temperature controller, pressure maintenance, time delay device, relay, overload protection and other mutual combination to achieve the functions of automatic start and stop and maintenance of the water temperature.

The three systems constitute an industrial chiller. Special design can meet the needs of different industries. The professional level enables the service life of industrial chillers to be extended and can meet the needs of different customers.
