  • Intelligent controller for refrigerating and air conditioning systems
    Patent number: 7975498
    Abstract: An intelligent controller (68), adapted for regulating operation of either a refrigeration system or an air conditioning system (20), receives an output electrical signal produced by a pressure sensor (72, 74, 76, 78) included in the system (20). Responsive to the received electrical signal, the intelligent controller (68) energizes operation of a motor (24) that drives a compressor (22) included in the system (20). The programmable electronic circuit (68) performs a calibration operation in which the circuit (68) measures the output electrical signal received from the pressure sensor (72, 74, 76, 78) and stores as an offset the value so measured. The programmable electronic circuit (68) subsequently applies the stored offset for adjusting a value of the output electrical signal received from the pressure sensor (72, 74, 76, 78) during normal operation of the system (20).
