Briefly Describe The Working Principle Of Commercial Refrigerators

Similar to the principle used in ordinary refrigerators, commercial refrigerators use a compressor to compress liquid refrigerant into high-temperature and high-pressure gaseous refrigerant, which is then sent to the condenser for heat dissipation and becomes low-temperature and high-pressure liquid refrigerant. Therefore, the condenser blows out hot air. Then it goes to the throttling device (usually a capillary tube) for throttling and pressure reduction, and enters the evaporator. As the refrigerant reaches the evaporator through the capillary tube, the space suddenly increases and the pressure decreases. The liquid refrigerant will vaporize and become a gaseous low-temperature refrigerant, absorbing a large amount of heat. The evaporator will become cold, and direct cooling or air cooling can be used to achieve cooling inside the cabinet.
