An Air Conditioning system involves many components such as the Compressor, Condenser, Evaporator, and Accumulator. If your car A/C system does not work effectively, you will not be able to enjoy the usually cooling effect. The Expansion valve is one of the major components in your BMW A/C system. The Expansion valve regulates the flow of gas inside the A/C system and it controls the flow of refrigerant according to how cool you want it to get inside your car.
You have the ability to control the temperature of your BMW A/C system. If you crank up the A/C system, the Expansion valve expands and releases more refrigerant through the system. If you turn the A/C System down, the Expansion valve shrinks which decreases the amount of refrigerant.
