REFRIGERATING PLANT Russian patent published in 1998 - IPC

FIELD: refrigerating engineering; refrigerating plants equipped with compressor having cooled oil bath and jacket filled with liquid cooling agent used for cooling the compressor; industries where refrigeration is required, especially in regions where water deficit is present. SUBSTANCE: refrigerating plant includes the following units mounted in closed loop: compressor with cooled oil bath and jacket, condenser, receiver, throttle valve and evaporator; besides that, plant is additionally provided with reservoir in whose lower portion heat exchanger is mounted. Reservoir is connected to liquid pipe line between receiver and cooled oil bath and jacket and is also connected with loop and receiver by means of vapor pipe lines. Heat exchanger is connected with cooling jacket and loop by means of vapor pipe line. Vapor pipe lines running from heat exchanger and reservoir to loop are fitted with pressure differential regulators and vapor pipe lines laid between receiver and reservoir, cooling jacket and loop of liquid pipelines before and after reservoir are fitted with solenoid valves. Layer of material of capillary- porous structure located inside cooling jacket ensures thermal contact with cooled surfaces of compressor. Perforated inserts are located in zones of cooling jacket-supply from liquid pipe line and discharge to vapor pipe line. EFFECT: enhanced efficiency. 2 cl, 2 dwg
