ABSTRACT:
A refrigeration system which has in a closed loop a compressor body, with a cooling jacket, for compressing a refrigerant, a condenser for condensing the compressed refrigerant to a liquid refrigerant, and a condensed liquid pump for compressor body cooling. The compressor body is thermally coupled to a cooling jacket, through which a cooling liquid flows. The condensed liquid pump pumps condensed liquid refrigerant from the condenser through the cooling jacket, cooling the compressor body, and then to the compressor cylinder head exhaust manifold, where the liquid refrigerant mixes with and cools the hot compressor discharge gas.
