  • Method and apparatus for calculating torque of variable capacity type compressor
    Patent number: 5285649
    Abstract: In a method for calculating torque for a variable capacity type compressor provided in a refrigeration circuit and driven by an engine to compress and discharge refrigerant to be circulated through a heat exchanger in the refrigerant circuit, a rotational speed of the compressor is calculated, a quantity of refrigerant discharged from the compressor and pressure of refrigerant in high-pressure side are calculated, a capacity of the discharged refrigerant during operation of the compressor is calculated based on the calculated discharged refrigerant quantity and the calculated rotational speed, and the torque is calculated based on the calculated refrigerant pressure and the calculated capacity.
