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 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 refrigerant.
If you increase the cooling level of your Acura A/C system, the Expansion valve expands to release more refrigerant. And if you decrease the level, it slows down the flow of refrigerant. The Expansion valve 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 malfunctions in your car A/C Expansion valve, you must look into the issue and replace it as early as possible. Discount AC Parts is the best place to purchase quality car parts.
