The operation of the chiller system is through three interrelated systems: a refrigerant circulation system, a water circulation system, and an electrical control system.
Compressor: The compressor is the core component of the entire refrigeration system and the source of refrigerant compression. Its function is to convert the input electrical energy into mechanical energy to compress the refrigerant.
Chiller circulatory 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. The liquid refrigerant is completely evaporated to a gaseous state and then sucked and compressed by the compressor (pressure and temperature increase). The gaseous refrigerant absorbs heat through a condenser (air-cooled/water-cooled), condenses into a liquid, and is throttled by a thermal expansion valve (or capillary tube) to become a low-temperature low-pressure refrigerant and enters the evaporator to complete the refrigerant circulation process.
