Expansion Valve: Description and Operation
The expansion valve regulates the flow of liquid refrigerant into the core of the evaporator. As the condensed liquid refrigerant is released through the
expansion valve, the refrigerant pressure decreases considerably. As the pressure drops, the refrigerant temperature drops. The refrigerant passing
through the expansion valve transforms from a high-pressure, medium-temperature liquid into a low-pressure, low-temperature liquid.
