Heat pump txv valve

The thermostatic expansion valve ( TXV ) is a precision device, which is designed to regulate the rate at which liquid refrigerant flows into the evaporator. This controlled flow is necessary to maximize the efficiency of the evaporator while preventing excess liquid refrigerant from returning to the compressor (floodback). Additionally, the air conditioner or heat pump will not realize the rated efficiency levels of the equipment.


Despite what is written or illustrated here it is always recommended to follow the manufacturers installation instructions. You have to analyze the other system vital signs before deciding the valve is suspect. You can see a more in depth explanation of TXV operation and illustrated failures in the “Troubleshooting Heat Pump Refrigerant Systems” and “Troubleshooting TXV’s” rental videos: Troubleshooting Heat Pump Refrigerant Systems.

In this video we take a look at how the thermostatic expansion valve or TXV works in a HVAC refrigeration system and the basic working principles that allow it to meter the flow of refrigerant. There are different set ups for heat pumps but they usually have TXV or Piston, if there is two metering devices (outdoor and indoor) they will have a check valve diversion path depending on flow. Expansion Valve Replacement on Heat Pump. The Symptoms of a Restricted TXV How to identify when a liquid-line restriction is starving a system of refrigerant Figure 1: A healthy, happy, and unrestricted thermostatic expansion valve. Trane XBunit was freezing, repair guy said it was thermal expansion valve ( TXV ) and told me it wuld be $3for two techs two hours to come out and fix it.


I show the symptoms of a stuck reversing valve. This one is stuck partway and is bypassing from high side to low side. What it looks like to have a Bad TXV Compared to just a Low Charge.

I have a Rheem Acheiver heat pump. I am having problems with it. I called a contractor today and he said the txv valve is bad. It will take about wks to get the part and was quoted a price of $5– $600. So Many TXVs to Troubleshoot.


Liquid must be going to the TXV in order for the valve to work properly. For a heat pump that needs to be fixe no need to be “heated”! When using a TXV manufacturers recommend also installing a hard-start capacitor in your heat pump.


Select the TXV to correspond with the tonnage of your air conditioner or heat pump , as well as to match the type of refrigerant your systems uses, R-(standard) or R-410A (new alternative). A thermostatic expansion valve ( TXV ) has that same purpose – it regulates the rate at which the refrigerant flows into the heat pump evaporator increasing its efficiency. The importance of a TEV or TXV in heat pumps is enormous.


A way reversing valve is used to swap the functions of the evaporator and condenser in order to change from cooling to heating mode. To avoid confusion it is common practice to call heat pump coils the indoor and outdoor coil. The diagram below shows a heat pump piping layout.


If the valve has all mechanical fittings and you. A heat pump condenser, or condensing unit, is the large box-like unit that is located outside your home. They have a large fan on the top or side of the side of the condenser, and if you live in an area where you get snow on occasion, the heat pump condenser may be elevated onto small risers, to keep snow from accumulating onto the sides.


Find great deals on eBay for heat pump txv valve.

In a heat pump system when the reversing valve is energized (cool mode), the unit will run in cool mode and the refrigerant will. The TXV ’s used for heat pump applications have special low superheat ranges. Alco’s heat pump TXV ’s have an “HCA” bulb charge. Above degrees F ambient, this charge operates the same as any regular air conditioning bulb charge with standard superheat.

A reversing valve a type of valve and is a component in a heat pump , that changes the direction of refrigerant flow. By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa. Valve might hunt to try and control load due to low load or flash gas entering the TXV. Do not rush when charging a.
