An expansion valve meters the flow of liquid refrigerant into the evaporator where it changes from a liquid to a gas by absorbing heat from the cabin air. A thermostatic expansion valve (txv) (see figure 1) is a refrigeration and air conditioning throttling device that controls the amount of refrigerant liquid injected into a system’s evaporator—based on the evaporator outlet temperature and pressure—called the superheat.

A Thermal Expansion Valve Keeps The System Running As Efficiently As Possible While Protecting The Ac Compressor From Damage That Could Be Caused By Liquid Refrigerant.

A thermal expansion valve (often abbreviated as tev, txv, or tx valve) is a component in refrigeration and air conditioning systems that controls the amount of refrigerant flow into the coil thereby controlling the superheating at the outlet of the evaporator. I looked at the expansion valve and dont see anything like a normal capillary tube type where the temp is monitored by it and opens and closes the expa. Many car makers now use automotive ac expansion valve in their ac systems.
