The law of the suction and exhaust temperature of the 冷却装置

First of all, under normal circumstances, there must be a temperature difference between the suction and exhaust temperatures.

It should be known that the suction temperature is the temperature of the refrigerant after the evaporation process is completed. After being sucked into the working chamber of the compressor, it is compressed by the compressor and then discharged. If there is no temperature difference, it means that the compressor is not working. Therefore, under normal conditions There must be a temperature difference between the suction and exhaust temperatures.

Second, the suction temperature is higher than the evaporation temperature.

After the evaporation process, the refrigerant will enter the suction end of the compressor, so many people think that the suction temperature and the evaporation temperature are the same, but this is not the case – the suction temperature of the refrigerator will be higher than the evaporation temperature, which is Because there is a suction line between the evaporation process and the suction port, which forms a certain heat preservation capacity, and the suction temperature is higher than the evaporation temperature, which will not affect the normal operation of the compressor.
