How do thermal expansion valves work
WebThe expansion valve is a passive orifice through which the liquid refrigerant is forced by the pressure difference between the condensing and the evaporating conditions. If a system could always operate at fixed conditions, correctly charged, a simple restriction would fulfil the requirement. WebA thermal expansion valve, also known as a thermostatic expansion valve, TXV, TEV, or TV valve, is an integral component for air conditioning systems and vapor-compression refrigeration. It manages the quantity of refrigerant released into the evaporator. It regulates the high pressure of the refrigerant that flows out of the evaporator to low ...
