  • Heat pump refrigerant charge control system
    Patent number: 4484452
    Abstract: A microcomputer controlled charge control system for modulating charge in a heat pump refrigerant circuit. A charge receiver has its interior in thermal communication with the compressor suction line and has a single charge flow line connected via a charge control valve to the refrigerant circuit at a point intermediate two controllable expansion valves in the high side of the circuit. Super-heating and subcooling strategies are employed to maintain the charge level in the circuit at optimum performance levels, automatically adapting to changes in environmental load conditions on the heat pump heat exchange coils.
