An Expansion device 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, or Cooling coil. According to your cooling demands, the expansion valve releases the cool refrigerants. If you increase the cooling level of your BMW A/C system, the expansion valve expands to release the refrigerant. And if you decrease the level, it slows down the flow of refrigerant.
The expansion device has three pressure points to regulate the amount of refrigerant entering the evaporators. They are the evaporator, bulb and the spring. If you find any problems with your car A/C expansion device, you must have it inspected and replaced immediately. Discount AC Parts is the best place to get the right car parts.
