Expansion Valve

 

The expansion valve determines the correct amount of refrigerant going into the evaporator from the condenser through the filter, and it lowers the pressure of the refrigerant drastically. When the compressor starts, the expansion valve opens and the liquid refrigerant flows through a strainer in the high-pressure liquid inlet once in the expansion valve, the refrigerant is properly pressurized.

As the evaporator calls for more refrigerants, the expansion valve allows the required amount of low-pressure liquid refrigerant into the coils. The expansion valve maintains the delicate balance between the heat load and the cooling efficiency of the evaporator.
