WebThe thermostatic expansion valve, also known as a TXV valve, is a component within a refrigeration device that controls the amount of refrigerant that enters into the system. When the TXV valve is faulty, the evaporator within the system can either have too much refrigerant or not enough.

How to Diagnose a Thermostatic Expansion Valve Failure

A thermal expansion valve is a key element to a heat pump; this is the cycle that makes air conditioning, or air cooling, possible. A basic refrigeration cycle consists of four major elements: a compressor, a condenser, a metering device and an evaporator. As a refrigerant passes through a circuit containing these four elements, air conditioning occurs. The cycle starts when refrigerant enter… WebFeb 17, 2024 · Understanding the Function of the TXV.
