How Does the Air Conditioning Expansion Valve Work?

The air conditioner expansion valve receives high-pressure liquid refrigerant from the condenser, reducing pressure and temperature. Then, it meters the flow of refrigerant into the evaporator based on cooling demand. The expansion valve regulates refrigerant flow by sensing temperature and pressure conditions in the evaporator.

What is the Function of the Ac Expansion Valve?

The air-conditioning expansion valve has two main functions in the air-conditioning system. One is to have a certain throttling effect on the air-conditioning. The high-temperature and high-pressure liquid air-conditioning refrigerant will become a low-temperature and low-pressure mist hydraulic refrigerant after passing through the expansion valve.

The other function is to control the flow of air-conditioning refrigerant. The liquid refrigerant entering the evaporator will become gaseous through evaporation, and the expansion valve controls the flow of air-conditioning refrigerant to ensure that the outlet of the evaporator is completely gaseous refrigerant.

Why Air Conditioning Expansion Valve Doesn't Work?

1. The failure of the desiccant and the dirt in the system;
2. The temperature-sensitive element or diaphragm of the expansion valve fails, and the installation position of the capillary is loose and shifted.

What are the Signs of Malfunctioning of Them?

Some common signs of A/C expansion valve failure in construction machinery include insufficient cooling, inconsistent cooling, frost or ice on the evaporator, and high or low-pressure readings on the A/C system gauge.

Air Conditioning Expansion Valve Repair or Replacement?

Mostly, a bad A/C expansion valve cannot be repaired and needs to be replaced. Because this kind of valve is a precision part, you can ask professional technicians for details.

Does the Air Conditioner Expansion Valve Need To Be Replaced Regularly?

Honestly, I can't give you an answer, because the air conditioner expansion valve usually doesn't have a predetermined lifespan, but it is recommended to check the A/C system regularly and replace it if there are signs of failure.
