Throttling elements for refrigerated trucks2022-03-30
The high-pressure and normal-temperature refrigerant liquid is directly sent to the low-temperature scale evaporator, and the pressure of the refrigerant liquid is reduced according to the corresponding principle of saturation pressure and saturation temperature, thereby reducing the temperature of the refrigerant liquid. The high-pressure and normal-temperature refrigerant liquid is passed through the pressure-reducing device—the throttling element to obtain low-temperature and low-pressure refrigerant, which is then sent to the evaporator to absorb heat and evaporate. In daily life, refrigerators and air conditioners often use capillary tubes as throttling elements.
