The expansion valve, also known as a metering device, plays a vital role in the air conditioning (AC) system. It controls the amount of refrigerant that enters the evaporator, ensuring that the refrigerant changes from a high-pressure liquid to a low-pressure mist. This precise regulation is essential for efficient heat absorption within the evaporator, leading to effective cooling of the cabin air. A properly functioning expansion valve contributes to the overall comfort of your driving experience, especially during hot weather.
