Air conditioning systems are often located in homes and vehicles.
Air conditioning txv 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.
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.
However the undercharged system will have low condenser subcooling levels.
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.
Service technicians often confuse an undercharged system with a restricted metering device.
The symptoms of a system with a restricted thermostatic expansion valve txv are very similar to those of a system with a refrigerant undercharge.
Although often described as a thermostatic valve an expansion valve does not.
Txv thermostatic expansion valve air conditioning systems contain a receiver drier that cleans and absorbs moisture from the refrigerant.
There are many components to an air conditioning system including the compressor condenser evaporator and thermal expansion valve or txv.
A thermal expansion valve causes the air conditioner to operate more efficiently.
This moisture freezes in the expansion valve and deprives the evaporator of refrigerant.
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.
It uses a sensing bulb or disc that opens or closes the diaphragm to allow the refrigerant to pass through.
