<P>PROBLEM TO BE SOLVED: To provide a high temperature regenerator for an absorption refrigerator capable of suppressing corrosion of a liquid pipe for heat exchange, improving heat exchanging performance and preventing burnout of a furnace frame. <P>SOLUTION: A high temperature regenerator is constituted of a double-shell of an inner cylinder 2 and an outer cylinder 3, and the inner cylinder 2 is provided with a heat exchange zone 4 where a high temperature gas 13 is allowed to flow among the liquid pipes 6 vertically disposed in a group to be heated. The inner cylinder 2 has the box-shape, and the outer cylinder 3 is a square cylindrical body at least at a part surrounding the inner cylinder. Opposed spaces of both are applied as jackets for circulating an absorption liquid, and directly and indirectly communicated with a gas liquid reservoir 9 defined above the inner cylinder 2. Spacers 26 are disposed in both jackets, and paths of the same direction are formed in each of the jackets. An inlet 31 for allowing the absorption liquid to flow in from a high temperature heat exchanger, is formed on each of paths of the jackets under the inner cylinder, and the absorption liquid is forcibly circulated in a liquid pipe and each jacket toward the gas liquid reservoir 9. Stagnation does not generate in the rising flow, heating in an empty state can be prevented, and corrosion of a heat transfer face can be also prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
