  • Low refrigerant charge detection system
    Patent number: 5457965
    Abstract: An apparatus for detecting is disclosed for detecting a low level of refrigerant circulating through a motor vehicle refrigerant circuit. The apparatus comprises an electronic logic module, and a pressure transducer and a thermistor preferably located in the refrigerant circuit between the compressor and the evaporator. The pressure transducer generates a signal indicative of the refrigerant pressure, from which the module derives a saturation temperature of the refrigerant. The saturation temperature is compared with the measured temperature to determine if a superheat condition exists indicative of low refrigerant charge exists. When the refrigerant remains at a predetermined level of superheating, the compressor clutch is disengaged to interrupt circulation through the refrigerant circuit.
