The expansion valve is critical to the operation of your air conditioning so if it is malfunctioning, it can easily render your air conditioning system inoperable. It is connected between the receiver (containing liquid refrigerant at high pressure) and. As the high pressure liquid refrigerant bursts through the small gap between the valve seat.

It Is Also Known As Throttling Device.

High pressure side and the low pressure side. It is a long narrow winded tube. A compressor, a condenser, a metering device and an evaporator.

The Orifice Within The Valve Does Not Remove Heat, But Only Reduces Pressure.

The expansion valve, also known as a thermostatic expansion valve (tev), is an ac component that’s designed to regulate the flow of refrigerant by removing pressure from it. The expansion valve is designed so that the temperature of the refrigerant at the evaporator outlet must have 8 to 12°f (4 to 7°c) of superheat before more refrigerant is allowed to enter the evaporator. Inside the expansion valve you will typically find the following main components.

The Expansion Valve Is A Usually Just A Very Small Opening With An Expansion Void After The Opening So Really The Only Way The Expansion Valve Can Malfunction Is If It Becomes Clogged.

On the adjacent side is a removable cap where the superheat is adjustable. In the illustration below, you’ll see that low pressure gas flows out. The diaphragm which is a strong, thin flexible material, typically metal, which can flex to apply pressure to the pin.

How The Expansion Valve Helps Cool Down Your Home.

Increasing the pressure of refrigerant also increases its temperature, literally packing its molecules more tightly together. It’s all part of how your ac cools. 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.

This Is How Cool Air Can Come Out Of The Air.

Now many positive things go along with proper superheat control. The adjusted tension of this spring is the determining factor in the opening and closing of the expansion valve. As the high pressure liquid refrigerant bursts through the small gap between the valve seat.
