An Air Conditioning system involves many components such as the Compressor, Condenser, Evaporator, and Accumulator. The Expansion device is one of the major components in the Air Conditioning system. It regulates the flow of gas inside your car Air Conditioning system. The Expansion valve receives the cool liquid refrigerant under high pressure that is circulated by the Receiver-Drier. It allows the liquid to pass through an orifice tube by sensing the temperature of the Evaporator, or cooling coil.
According to your cooling demands, the Expansion valve releases refrigerant. If you increase the cooling level of your Audi A/C system, the Expansion valve expands to release more refrigerant. And if you decrease the level, it slows down the flow of refrigerant. If there is a problem with the A/C Expansion device then you need to look into the issue as soon as possible.
