Abstract

597,141. Refrigerating. BERNAT, R., and BERNAT, H. Aug. 10, 1945, Nos. 20630 and 20631. Convention dates, Sept. 8, 1943, and Oct. 22, 1943. [Class 29] Absorption systems.-In a continuous system absorption takes place in two successive stages, first in a low-pressure absorber 11 in which the pressure is equal to that in the evaporator, and then in a high pressure absorber 15 to which the undissolved gas and the liquor from the absorber 11 are forced by a compressor 14 and a pump 13 respectively. Two boilers 2, 4, are employed, the boiler 4 being heated to a higher temperature than the boiler 2 by steam supplied at 46 to a coil 5. From the coil 5 the steam passes through a valve 43 to a coil 1 in the boiler 2, being mixed at 48 with exhaust gases from an engine, supplied through a pipe 44. Weak liquor from the boiler 2 passes by a pipe 30 to the boiler 4 where more ammonia is driven off and passes by a pipe 20 to a rectifier 3 in the upper part of the boiler 2 and thence to a further rectifier 6 cooled by strong liquor from the absorbers. Liquid separated in the rectifier 6 returns to the boiler 2 by a pipe 42. From the rectifier 6 the ammonia vapour passes to a condenser 7, the liquid ammonia collecting in a vessel 8 whence it passes to a subcooler 9 and the evaporator 10. The vapour from the evaporator passes through the sub-cooler 9 and by a pipe 28 to the first absorber 11 supplied with weak liquor from the boiler 4 through pipe 31, liquid heat-exchanger 17 and pipe 32. The liquid and vapour from the first absorber are separated in a vessel 12 and are forced by pump 13 and compressor 14 respectively into the second absorber 15. A pump 16 delivers the strong liquor from the second absorber through a pipe 39 to the rectifier 6 and thence by pipe 40, liquid heat exchanger 17 and pipe 41 to the boiler 2. Valves 26, 33 regulate the flow. The boilers may comprise horizontal double-walled tubes the annular space of which is supplied with the steam and exhaust gases, and separating chambers may be provided for the ammonia and weak liquors.
