A closed refrigeration circuit comprises in series a compressor, a condenser, a drier-filter, a capillary tube, an evaporator, and a conduit connecting the evaporator to the condenser and traversing the drier-filter. A refrigerant fluid circulates in operation through the circuit. With this arrangement the connecting conduit is in heat-exchanging relationship with the drier-filter, thereby avoiding the need for a separate heat exchanger.
