water chiller Cooling principle

Date:Jul 28, 2020

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


Compressor: The compressor is the core component of the entire refrigeration system and the source of power for refrigerant compression. Its function is to convert the input electrical energy into mechanical energy and compress the refrigerant.


Refrigerant circulation system of chiller:


The liquid refrigerant in the evaporator absorbs the heat in the water and starts to evaporate. Eventually, a certain temperature difference is formed between the refrigerant and the water. The liquid refrigerant is also completely evaporated and becomes gaseous and then sucked by the compressor and compressed (pressure and temperature increase) , The gaseous refrigerant absorbs heat through the 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 and low-pressure refrigerant to enter the evaporator, completing the refrigerant cycle process.
