Another dividing point is air conditioner compressors. In order to explain the purpose of an expansion valve requires first explaining the basics of how refrigerant works in an air conditioner. Most likely it is an orifice tube inside the line near the dryer.

Step 1 Attach the gauges to the AC system by locating the low-pressure and high-pressure service ports.

This part also depressurizes the refrigerant until it becomes cold enough to cool down the warm air passing through. The sensing disc may be. The expansion device is the fourth major component in air conditioner units.

This reaction of expansion causes its pressure drop also taking the temperature down with it. The purpose of the valve is to manage how much refrigerant liquid can flow throughout this system. Air conditioner expansion valve is the divided point between the low side and the high side of the air conditioner units.

Sure you can remove the compressor lines from the expansion valve from the engine bay but that is only half the connections you must unconnect. The low-pressure port can be found on the low side line between the accumulator sometimes on the accumulator and the compressor.
