Abstract

888,446. Refrigerating. LINDE'S EISMASCHINEN A.G. GES FUR. Dec. 15, 1959 [Dec. 18, 1958], No. 42587/59. Class 29 In a compression system, solvent for the lubricant is added to the refrigerant, the mixed lubricant and solvent being removed. The refrigerant may be ammonia or carbon dioxide and the solvent toluene, trichlorethylene, petroleum, paraffin, white spirit, turpentine or hydraulic oil. As shown, high pressure compressor 10 supplies refrigerant to condenser 12, reducing valve 14 and receiver 8 from which the liquid flows through a second reducing valve 16 to accumulator 2. From the latter the liquid falls through pipe 3 to the bottom of evaporator 1 the vapour from which enters accumulator 2. Vapour from the accumulator is drawn by low pressure compressor 6 which exhausts into receiver 8 and the latter is connected by pipe 9 to the suction of compressor 10. The pressure in evaporator 1 is less than atmospheric and hence solvent is drawn into pipe 3 from open reservoir 21. The mixed solvent and lubricant from pipe 3 enters trap 4 from pipe 3 and can be drawn off by cock 20. Sufficient solvent may be supplied to enter the evaporator to remove lubricant deposits from the walls thereof. Solvent may also be supplied to other parts of the system by pumps 22 . . . 25 and the mixture can be withdrawn from the condenser 12 and receiver 8. The withdrawn mixture can be separated, the components being returned to the system and the separating means may be embodied in the System.
