Summary: | A method of controllably charging a heat pump system with refrigerant until adequately charged for the cooling mode of operation, including checking the outdoor ambient temperature, injecting sufficient refrigerant to sustain safe compressor operation, operating the compressor at higher or lower rates depending upon the detected ambient temperature level and determining when to halt charging by monitoring indoor coil inlet and suction temperature differences in the heat pump system. |
