Title: Innovations by John H. Blair in Refrigerant Detection Systems
Introduction
John H. Blair is an accomplished inventor based in Westland, MI (US). He is known for his innovative contributions to the automotive industry, particularly in the field of refrigerant detection systems. His work has significantly impacted the efficiency and reliability of vehicle air conditioning systems.
Latest Patents
John H. Blair holds a patent for a Low Refrigerant Charge Detection System. This apparatus is designed to detect low levels of refrigerant circulating through a motor vehicle refrigerant circuit. The system includes an electronic logic module, a pressure transducer, and a thermistor, which are strategically placed within the refrigerant circuit. The pressure transducer generates a signal indicative of the refrigerant pressure, allowing the module to derive the saturation temperature of the refrigerant. By comparing the saturation temperature with the measured temperature, the system can determine if a superheat condition exists, which indicates a low refrigerant charge. If the refrigerant reaches a predetermined level of superheating, the compressor clutch is disengaged to interrupt circulation through the refrigerant circuit.
