ABSTRACT:
An improved refrigeration cycle in which a refrigerant vapor is compressed, condensed and then evaporated for cooling purposes by direct contact with a liquid to be cooled, the improvement comprising feeding a refrigerant vapor to an aqueous liquid sealed compressor; feeding compressor sealing aqueous liquid to the compressor; compressing the refrigerant vapor in the compressor and removing a mixture of compressed refrigerant vapor and aqueous liquid from the compressor; separating aqueous liquid from the refrigerant vapor and returning the aqueous liquid to the compressor; condensing the refrigerant vapor to a liquid, directly contacting the liquefied refrigerant with a liquid to be cooled; and, returning the refrigerant vapor to the compressor.
