ABSTRACT:
A refrigerating apparatus includes a compressor, a condenser, a capillary and an evaporator. A bypass conduit with a valve is arranged so that the refrigerant discharged from the compressor will bypass at least the condenser and the capillary so as to return to the inlet side of the compressor. The pressure or the temperature of the refrigerant in the apparatus is sensed by a sensor. When the sensed value is less than a prescribed value, the valve is opened to return the hot gas to the compressor. The compressor is driven for elevating its temperature.
