Explosion-proof Chiller Refrigeration Cycle System Principle


The explosion-proof chiller cools the water at room temperature to a certain temperature through the compressor of the chiller to strengthen the cooling of the mold or machine. It is used as a stand-alone chiller. The heat dissipation device is a built-in fan. There are three interrelated systems: refrigerant circulation system, Water circulation system, electrical automatic control system.cryogenic cooling chiller

The principle of the refrigerant cycle system: the liquid refrigerant in the evaporator absorbs the heat in the water and begins to evaporate, and finally a certain temperature difference is formed between the refrigerant and the water, and the liquid refrigerant is also completely evaporated into a gaseous state, and then sucked by the compressor And compressed (increased pressure and temperature), the gaseous refrigerant absorbs heat through the condenser 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.

1. Water circulation 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.

2. Electrical automatic control system: including the power supply part and the automatic control part.

3. The power supply part supplies power to compressors, fans, water pumps, etc. through contactors. The automatic control part includes thermostat, pressure protection, delayer, relay, overload protection, etc., which are combined to achieve automatic start and stop according to water temperature, protection and other functions. Explosion-proof chillers are usually divided into air-cooled and water-cooled according to the cooling form.
