An optical sensor is employed in a refrigerant shortage sensor 9 which detects the mixing ratio of gas and liquid of the refrigerant based on the amount of permeation of light. When the refrigerant becomes short, the ratio of mixing of gas to liquid is increased whereby the refrigerant shortage sensor 9 detects it and outputs an electric signal amplified by an amplifier 11. According to the conduction of the electric current, the solenoid coil 12 is excited and an automatic opening and closing switch 10 is put OFF. Accordingly, the driving power supply circuit of a compressor 2 is opened and the operation of the compressor 2 is stopped. For your reference, a self heat generating type thermistor can be used instead of the optical sensor.
