Abstract
A loss of refrigerant and/or high discharge temperature detection and control system for a reverse cycle refrigeration system by providing a fault indication whenever the temperature of the compressor discharge refrigerant is at or above a predetermined value (which value is a function of the magnitude of the outdoor air temperature) and which functions further by inhibiting the operation of the compressor of the reverse cycle refrigeration system whenever the temperature of the refrigerant at the compressor discharge exceeds a predetermined value above which the compressor would be damaged if it continued to operate.
