The importance of the thermal expansion valve of the chiller

The expansion valve is to control the amount of refrigerant supplied to the evaporator. The amount of refrigerant is related to the working effect of the evaporator, and the working effect affects the amount of liquid supplied by the expansion valve to the evaporator. Only by installing a thermal expansion valve can the entire system be able to It is self-consistent, so that it can continue to operate in a normal cycle.

Once there is no expansion valve, the refrigerant will directly enter and pass through the evaporator without considering the working conditions of the evaporator, which will cause the evaporator to work disorderly, which will affect the suction side of the evaporator. Because the ice water machine is a circulatory system with a node disorder , Other parts will also be messed up, so the refrigeration work cannot be completed normally.
