Two opposite ends of the first path respectively connected to a high-pressure outlet and a low-pressure inlet of the air conditioner compressor. Two pressure gauges are respectively mounted to the first path, one before the air conditioner compressor and the other after the air conditioner compressor relative to the flowing direction of the coolant in the first path for showing the difference of the pressure value of the coolant between passing before the air conditioner compressor and passing after the air conditioner compressor.
