Abstract: 298.603. Siemens - Schuckertwerke Akt.-Ges. Oct. 12, 1927, [Convention date]. Refrigerating, absorption machines and processes for.-In continuouslyacting machines, surplus liquid from the evaporator or cold generator is used to rectify the vapour passing from the generator. In a machine in which the pressure differences are maintained by columns of liquid, the liquid refrigerant flows from the evaporator 1 through the pipe 16 to the gas separator 8 over the shelves in which it flows in countercurrent to the gas received, together with entrained liquor, from the electrically-heated generator 9 and passing to the condenser 14. The strong liquor from the absorber 3 flows through the pipe 5 to the vessel 6, which communicates both with the separator 8 and the generator, and the weak liquor returns from the separator to the absorber through a pipe 12 forming a heat exchanger with the strong liquor pipe 5. The pressure in the separator may be increased by beating the refrigerator liquid in the vessel 17. In a modification, an inert pressure-equalizing gas circulates between the evaporator and the absorber. In another arrangement, in which the refrigerant is evolved from low temperature solution in a vessel 41, Fig. 3, the inert pressureequalizing gas, together with refrigerant vapour, is circulated between the absorber 45 and the vessel 41 by an injector 44 through which flows the rectified vapour from the separator 57. A portion of the solution entrained by the inert gas and the vapour passing from the absorber 45 to the vessel 41 flows through the pipe 60 and vessel 61 into the separator which receives vapour and entrained liquor from the generator 54. The rectified vapour from the separator 57 flows through the pipe 58 and a part passes on to the injector 44 while the remainder flows through the pipe 50 and equalizing tank 51 to the pipe 49 and assists the return of the weak liquor from the vessel 41 to the reabsorber 47, the strong liquor flowing through the pipe 48, which forms a heat exchanger with the pipe 49, to the vessel 41. Inert gas carried into the reabsorber by the weak liquor returns to the vessel 41 through the pipe 64 and de-aerating tank 63.
