A condensing stage of a refrigeration system. The condensing stage comprises means for returning a portion of the refrigerant of the refrigeration system at a downstream end of the condensing stage in a high-pressure liquid state to an upstream end of the condensing stage, to mix the portion of refrigerant with refrigerant in the high-pressure gas state prior to being fed to the condensing stage so as to increase the amount of heat released by volume of refrigerant in the condensing stage.
