Air Conditioning Txv Valve

This moisture freezes in the expansion valve and deprives the evaporator of refrigerant.

Air conditioning txv valve.

There are many components to an air conditioning system including the compressor condenser evaporator and thermal expansion valve or txv. Txv thermostatic expansion valve air conditioning systems contain a receiver drier that cleans and absorbs moisture from the 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. It is now extremely important for the hvac technician to understand the design and operation of this type of valve.

Air conditioning systems are often located in homes and vehicles. Service technicians often confuse an undercharged system with a restricted metering device. It uses a sensing bulb or disc that opens or closes the diaphragm to allow the refrigerant to pass through. If the drier becomes saturated with moisture it releases it at the hottest times of the day.

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. A thermal expansion valve causes the air conditioner to operate more efficiently. 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. Although often described as a thermostatic valve an expansion valve does not.

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.
