The operation of an industrial chiller system works through three interconnected systems: a refrigerant circulation system, a water circulation system, and an electrical control system.
The liquid refrigerant in the evaporator absorbs the heat in the water and begins to evaporate. Finally, a certain temperature difference is formed between the refrigerant and the water, and the liquid refrigerant is completely evaporated to a gaseous state, which is then sucked and compressed by the compressor (pressure and temperature increase). The gaseous refrigerant releases heat through a condenser (air-cooled/water-cooled) and condenses into a liquid. After the throttle valve (or capillary tube) is throttled, it becomes a low-temperature low-pressure refrigerant and enters the evaporator to complete the refrigerant cycle.
The pump is responsible for pumping water from the tank to the equipment that the user needs to cool. The chilled water takes the heat away and the temperature rises before returning to the chilled water tank.
