Compressor cooling system using heat exchanger pre-condenser, and compressor provided from a cooling system

Abstract

The present invention pertaining to the field of refrigeration equipments was designed to allow an unexpected construction and operation, and which is more efficient than the one achieved by using existing similar equipments. It is consisted of a compressor ( 1 ) comprised of a shell ( 2 ) within which it is located a compression cylinder ( 3 ), whereas from the shell ( 2 ) it is projected an inlet tube ( 5 ) from an evaporator and a discharge tube ( 6 ), which conducts the fluid into a condenser; at least one pre-condenser ( 7 ) associated with the compressor ( 1 ), the pre-condenser ( 7 ) being fed by a tubing ( 8 ) from the compression cylinder ( 3 ) located within the compressor ( 1 ), and equipped with an outlet tube ( 11 ); and a heat exchanger ( 91 ) internal to the outer region of the compressor ( 1 ) and cooperative with the pre-condenser ( 7 ) through the outlet tube ( 11 ) of the pre-condenser ( 7 ), the heat exchanger ( 91 ) comprising tubes attached around the shell ( 2 ) of the compressor ( 1 ).
