Description

Sept. 4, 1934. E. NOEBEL METHOD OF FILLING AN ABSORBER GENERATOR Filed Dec. 10, 1932 Patented Sept. 4, 1934 UNITED STATES METHOD OF FILLING ANZQBSOBBEB- GENERATOR Ernst Noebel, Berlin, Germany, assignor to Siemens-Schuckertwerke Aktiengesellschait, Berlm-Siemensstadt, Germany, a corporation of Germany Application December 10, 1932, Serial No. 646,73! In Germany December 14, 1931 4 Claims. (01. 62-179) My invention relates to a method of filling an absorber-generator ready to be built in an absorption refrigerating apparatus operating with solid absorbents.
According to the invention the absorbent is applied in a finely distributed form to metallic wool or cuttings or any other suitable heat conductor; whereupon the absorber-generator is charged with the metallic wool thus treatedand then the absorbent saturated, for instance, with ammonia after closure of the absorber-generator. On saturating the treated metallic wool, the ab-. sorbent applied tothe latter swells and fills up the entire space for the reception of the solid absorbent in the absorber-generator. According to the method of my invention the absorber-generator need not necessarily be provided inside with special heat conducting walls, since the heat conduction in the metallic wool is sufiicient to supply .heat to the solid absorbents and to carry 01f the heat of absorption. The preparation of the absorber-generator is thus greatly simplified and by far more economical. In order to apply the absorbent, for instance, strontium bromide, not ye}; enriched with the operating medium to a good heat conductor, metallic wool or similar substances may, for instance, be immersed into the liquefied absorbent, or the liquefied absorbent may be sprayed on the metallic wool. In both cases the metallic wool is coated with a thin vitreous layer of the absorbing medium.
In the accompanying drawing is illustrated an embodiment of my invention.
As shown in the drawing, the absorber-generator consists of a cylidrical jacket 1 and a concentric inner jacket 2 which are combined to a completely closed vessel by welding cambered end covers 3 and 4 thereto. The inner jacket 2 serves for the reception of the heating element which produces the heat during the generating period.
The cover 4 isprovided with a branch 5 to which a gas conduit is connected leading to the condenser (not shown). 6 denotes a thermometer pocket projecting into the interior 'of the abouter jacket 1 and the inner jacket 2 are combined by welding the cover-i3 thereto. At the open end of the vessel thus formed metallic wool '7 coated with pure absorbing medium in the above-described manner is charged in said vessel, care being taken to uniformly fill the container; with the'filling medium by ramming the charge to such an extent as to permit the absorbent, owing to the subsequent saturation with the operating medium, to swell up in the desired manner, so that a compact, finely porous and good heat conducting mass results, which firmly contacts with the walls of the absorber-generator. After the vessel has been completely charged the cover 4 is welded thereto; whereupon the absorbing medium is saturated with the operating medium. In such an absorber-generator, the metallic wool serves chiefly to conduct the heat to the walls thereof. Since the filling material is highly porous, the vaporous operating medium maybe easily supplied to or discharged from all points of the absorber-generator. No special heat conducting walls being necessary inside the space of the absorber-generator, the latter is consequently utilized to a higher degree.
The metallic wool is introduced into the absorber-generator at a temperature of about 300 to 400 centigrade immediately after the immersion into the liquefied absorbing medium or after spraying the liquefied absorbing medium in a heated state on the metallic wool. In this manner, the absorbing medium is prevented to a great extent from taking up moisture so that a reliable operation of the refrigerating apparatus is ensured, since slight traces of moisture in the solid absorbent may give rise to serious troubles. In the method hitherto employed, it was necessary to heat the boiler after charging it with the absorbing medium so as to remove the residual moisture from the absorbing medium. This meassubstance.
2. A method of preparing a filling mass for the generator-absorber of an absorption apparatus in which a solid absorbent capable of being swelled is utilized, consisting in immersing metallic wool in the liquefied absorbing medium so as to provide the metallic wool with a coat of said absorbing substance.
3. A filling material for generator-absorbers of absorption apparatus in which a solid absorbent capable of being swelled is utilized consisting of dium so as to provide the heat conducting material with a coat of said absorbing medium, charging the generator-absorber with the heat conducting material thus prepared, closing the generator-absorber and saturating the absorbing medium with the operating medium.
