System Composition of Industrial Chiller

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

water circulatory system:

The water pump is responsible for pumping water from the water tank to the equipment that the user needs to cool. The chilled water takes away the heat and then the temperature rises, and then returns to the chilled water tank.

Refrigerant circulation system of industrial chiller:

The liquid refrigerant in the evaporator absorbs the heat in the water and starts to evaporate. Finally, a certain temperature difference is formed between the refrigerant and the water, and the liquid refrigerant also completely evaporates into a gaseous state, which is then sucked in and compressed by the compressor (the pressure and temperature increase). ), 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), it becomes a low temperature and low pressure refrigerant and enters the evaporator to complete the refrigerant cycle process.

Electrical automatic control system:

The electrical automatic control system includes the power supply part and the automatic control part. The power supply part supplies power to compressors, fans, water pumps, etc. through contactors.

The automatic control part includes thermostat, pressure protection, delay device, relay, overload protection, etc. to achieve automatic start-stop, protection and other functions according to the water temperature.
