What Is a TXV Valve?
A TXV valve stands forthermal expansion valveand is a precise component in AC system thatcontrols the amount of refrigerant that flows into the evaporator．This is important because the controlled flow is necessary tomaximize your AC’s efficiencywhilepreventing refrigerant backflowto the compressor. Because of their function, TXV valves are often referred to as “metering devices".
A Closer Look at the TXV Valve
Your TXV valve plays a very important role in keeping your AC system running properly, so it’s worth noting how this valve works under normal conditions.
The flow of the liquid refrigerant is hindered by the valve pin. As the flow is restricted, the pressure in the refrigerant drops, causing a small amount of the refrigerant to be converted to gas form as a response to the drop in pressure. This “flash gas” combines with the rest of the low-pressure liquid refrigerant and moves on to the evaporator. The rest of the liquid refrigerant is then “boiled off” until it becomes a gas and is capable of absorbing heat energy.
TXV Valve Specificity
Your TXV valve is designed to doone thingonly: meter the proper amount of liquid refrigerant into the evaporator coil. Unfortunately, there are some misinformed people who believe this valve is capable of controlling other factors, includinghumidity, head pressure, suction pressure, and air temperature．The TXV valve is NOT meant to control any of these and assigning this valve to control this variable could result in thecompressor failingand limited system performance.
If your TXV valve fails, you can expect to see a change that directly affects the evaporator, leading to the evaporator being “overfed” (flooded) or “starved” (underfed). Anoverfed evaporator可以be observed by checking the refrigerant superheat value at the outlet of the evaporator and receiving alower than normalmeasurement. Inversely, astarved evaporator可以be observed by receiving ahigher than normal refrigerant superheat value．
A malfunctioning or faulty TXV valve may cause the higher or lower refrigerant superheat value, but keep in mind other factors may be inhibiting the valve’s performance and these possible suspects should be investigated before attempting to replace the TXV valve.
