Air Conditioning Txv Valve

Air conditioning systems are often located in homes and vehicles.

Air conditioning txv valve. Txv thermostatic expansion valve air conditioning systems contain a receiver drier that cleans and absorbs moisture from the refrigerant. Although often described as a thermostatic valve an expansion valve does not. The txv valve thermostatic expansion valve is an ac part designated for regulating the rate of flow of refrigerant in your air conditioning system as you can imagine you need this component to operate properly in order for your system to work efficiently and effectively. It is now extremely important for the hvac technician to understand the design and operation of this type of valve.

A thermal expansion valve or thermostatic 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 released into the evaporator and is intended to regulate the superheat of the vapor leaving the evaporator. This moisture freezes in the expansion valve and deprives the evaporator of refrigerant. If your air conditioner isn t cooling your house or car properly it may be low on refrigerant or it may have a faulty expansion. There are many components to an air conditioning system including the compressor condenser evaporator and thermal expansion valve or txv.

Since the minimum efficiency regulation changed to 13 seer in january 2006 most oem systems now incorporate a thermostatic expansion valve txv style metering device as the standard for air conditioning systems. The symptoms of a system with a restricted thermostatic expansion valve txv are very similar to those of a system with a refrigerant undercharge. Service technicians often confuse an undercharged system with a restricted metering device. An expansion valve also called a tvx valve regulates the flow of refrigerant inside of a cooling system.

However the undercharged system will have low condenser subcooling levels.
