FIELD: machine building.
SUBSTANCE: refrigerating compressor including drive motor and compressor unit, which compresses coolant coming through suction inlet and releases it through pressure outlet hole. Refrigerating compressor has compressor control system integrated into compressor control system, which determines compressor state by means of state value, which corresponds to saturation first temperature in suction inlet, and by means of second state value, which corresponds to saturation second temperature in discharge outlet, which compares compressor state with allowable compressor states located in working diagram preset working area and which, if compressor state comes out of working area, triggers refrigerating compressor switching off.
EFFECT: invention is aimed at ensuring operational reliability.
