What is the role of the refrigerant in the air-cooled chiller?

Air-cooled chiller is mainly a professional equipment to achieve the purpose of the process through the cooling form, in this process, need the assistance of refrigerant, refrigerant in the equipment refrigeration Continuous cycle operation and then change their own situation to achieve the effect of cooling. When the equipment is also circulating without refrigerant. Let us introduce the role of refrigerant in the air-cooled chiller. 1, the refrigerant change in the throttle element Because the refrigerant has become full liquid, so when the full liquid refrigerant flows through the throttle element, it will drop from condensation pressure to evaporation pressure, and the temperature drops from condensation temperature to steam 2. Change of the refrigerant in the condenser After the superheated vapor enters the condenser, because the pressure condition does not change, it will first emit a part of the heat, so that the refrigerant superheated vapor is cooled into full steam. still at this time However, under isothermal conditions, the full vapor will continue to release heat and condensation and constantly produce full liquid 3. Change of refrigerant in the compressor Refrigerant is from the end of the air-cooled chiller evaporator into the suction port of the compressor, and completes the process of refrigerant steam compression into superheated steam in the refrigeration compressor, the pressure is also It is increased from evaporation pressure to condensation pressure 4. Change of the refrigerant in the evaporator When the refrigerant enters the evaporator of the air-cooled chiller, because of the heat absorbed by the cooling medium and constant evaporation, the refrigerant under constant temperature conditions is constantly vaporized, from And less liquid, more and more steam. When the refrigerant liquid is all vaporized into full steam, it will return to the compressor suction inlet, so that the cycle operation completes the refrigeration
