Variation of refrigerant in air-cooled chiller refrigeration compressor
The refrigerant enters the suction port of the compressor from the end of the air-cooled chiller evaporator, and completes the process of compressing the refrigerant vapor into superheated steam in the refrigeration compressor, and the pressure is also raised from the evaporation pressure to the condensing pressure. After the superheated steam enters the air-cooled chiller condenser, since the pressure condition does not change, a part of the heat is first emitted to cool the refrigerant superheated vapor to a saturated vapor. Since this time is still under isothermal conditions, the saturated vapor will continue to vent heat and condense and continuously produce a saturated liquid. The longer the condensation time, the more saturated liquid will be, and the saturated vapor will decrease. The final result is that the refrigerant vapor is completely condensed into a saturated liquid. When the refrigerant enters the air-cooled chiller evaporator, it is absorbed by the cooling medium. The heat and constant evaporation, the refrigerant is continuously vaporized under constant temperature conditions, so that the liquid is getting less and less, and the steam is getting more and more. When the refrigerant liquid is completely vaporized to become saturated vapor, it is returned to the compressor suction port of the air-cooled chiller to recirculate the above changes.
