The Air Conditioner provides you with cool air inside your BMW. 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 cool liquid refrigerant under high pressure circulated by the receiver-drier. It allows the liquid to pass through an orifice tube by sensing the temperature of the evaporator. The role of the A/C Expansion device is important in varying the flow of refrigerant according to the cooling demands.
When you turn your air conditioning up, the A/C expansion device expands to release more refrigerant. If you turn you air conditioning down, the A/C expansion device shrinks and slows down the refrigerant release level. If you find any problems with your BMW A/C expansion device, you need to find a replacement as early as possible.
