A complex device which has a big effect on system operations. Here’s a little insight to how it operates
A thermal expansion valve, or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve), is a component in vapor-compression refrigeration and air conditioning systems that controls the amount of refrigerant released into the evaporator and is intended to regulate the superheat of the refrigerant that flows out of the evaporator to a steady value.
Often more than not connected to a refrigerant distribution system which allows refrigerant liquid evaporate to absorb heat energy.
Proper maintenance ensures the health of equipment and optimum energy performance.
