Function of the AC Expansion Valve

The AC expansion valve is a crucial component of the car’s air conditioning system. It’s responsible for regulating the flow of refrigerant to maintain the desired temperature inside the vehicle. It operates by controlling the angle of an inclined plate, thereby adjusting the refrigerant flow. This is achieved through a duty cycle (variable voltage) signal from the Engine Control Unit (ECU).

The ECU receives data from various sensors, including ambient temperature, interior temperature, and refrigerant pressure sensors. Based on this information, the ECU sends a voltage signal to the expansion valve. A higher voltage results in a smaller opening (reduced refrigerant flow), and vice-versa. At 12V, the valve is fully closed. The expansion valve precisely controls the refrigerant flow, allowing the compressor to operate at optimal efficiency. A larger angle of the inclined plate corresponds to a larger piston stroke and maximum compressor output. A 90-degree angle signifies the compressor is inactive, similar to a mechanical clutch disengagement.
