The air conditioning (A/C) system helps keep the vehicle’s cabin comfortable by cooling and removing humidity from the air. The major components of the A/C system include the compressor, condenser, receiver-drier or accumulator, evaporator, and an orifice tube or expansion valve. These components work to move refrigerant through the system, converting it from a liquid to a gas, to provide cool air through the cabin vents. This is referred to as the refrigeration cycle. The cycle is split into two main intervals of high pressure and low pressure, based on the state of the refrigerant. On the high pressure side, the compressor pressurizes cool, low-pressure gas refrigerant, converting it to high-pressure, high-temperature gas. The gas then flows into the condenser where it is cooled by air, turning the gas back into a liquid. This high pressure liquid then goes to the receiver-drier to filter out any moisture to help protect the A/C system from contaminated refrigerant. If the A/C system has an orifice tube, there will be an accumulator instead of a receiver-drier. This is usually found on the low pressure side of the A/C system, between the evaporator and compressor. After the refrigerant leaves the receiver-drier, it passes through an expansion valve, which allows it to expand into a low pressure liquid so it can be turned into gas in the evaporator. This process absorbs heat, causing the evaporator fins to become cold. The blower motor then pushes air across the evaporator, resulting in cold air through the vehicle’s vents.
