  • Method of operating a refrigerating unit with a refrigerant fluid circuit
    Patent number: 6330805
    Abstract: An air conditioning unit comprises a conventional refrigeration circuit including a conventional primary capillary for reducing the pressure of refrigerant flowing from a condenser outlet to an evaporator inlet. During abnormal operating conditions, i.e., when outside temperature is above a predetermined value, a secondary pressure reducing capillary bypasses the evaporator to supply refrigerant flowing out of the condenser to an inlet of a compressor, also responsive to refrigerant flowing out of the evaporator. Refrigerant flowing from the compressor flows into the condenser.
