Abstract:
A refrigeration system includes a compressor; a condenser connected to a first inlet of a separator which has: a vapor outlet connected to the compressor and a liquid outlet connected to an evaporator; a selecting valve having: a first vapor inlet connected to the evaporator; a second vapor inlet connected to the separator; and a vapor outlet connected to the compressor, the selecting valve being operated to selectively and alternatively communicate its first and second vapor inlets with its vapor outlet, so as to allow the compressor to draw vapor from the separator and from the evaporator; and a control unit for controlling the operation of the selecting valve.
