Abstract

The invention relates to a high power density sorption heat store, preferably for storing low-temperature heat, and is characterized in that a tube jacket 2 is provided with tube bottoms 3, 3′, and with heat exchange tubes 4, which penetrate the sorption layer 5 between the carrier floors 6, 6′; the mat layers 9, 9′ are in each case located in between; the tube jacket 2 essentially is enclosed by a working fluid tank 10 comprising the working fluid lines 11, 11′ including the valves 12, 12′, which in turn are in connection with the mat layers 9, 9′; and the dip tank 13, in the bottom area, comprises the passage 16; and heat exchange tubes 4 are proportionally equipped with ribs 27, and are loosely guided through openings 29 of the carrier floor 6′ and through the mat layer 9′ but are fixedly connected with the tube bottoms 3, 3′; and the ribs 27 are enclosed by a finely perforated network 28. The associated method relates to the autothermal vaporization of the working fluid, wherein in an unloading process in a first step, the liquid level in the working fluid tank 10 by flowing goes over from the stand-by condition a into the start condition b, and in a second step, a vaporization of the remaining liquid contents of the working fluid tank 10 takes place.

Dependent claims

A high power density sorption heat store, comprising:

a tube jacket which is provided with an upper and a lower tube bottom and with a plurality of heat exchange tubes each of which penetrate a sorption layer between an upper and a lower carrier floor;
wherein the lower tube bottom, in a bottom area of said high power density sorption heat store, is provided with a lower dome;
wherein the upper tube bottom, in a top area of said high power density sorption heat store, is provided with an upper dome
wherein an upper connecting sleeve for heat exchange is located on said upper dome and a lower connecting sleeve for the heat exchange is located on said lower dome;
wherein an upper and a lower mat layer are incorporated between the upper and the lower tube bottoms and the upper and the lower carrier floors;
wherein said tube jacket is essentially enclosed by a working fluid tank comprising
two working fluid lines each of which comprise a valve which is in connection
with said upper and said lower mat layer;
a dip tank, in said bottom area of said high power density sorption heat store, which comprises a passage and carries a coiled tube that is equipped with two lines;
a suction port which is present in said top area of said high power density sorption heat store;
wherein said suction port is connected to a) an aftercondenser and b) a vacuum pump via a suction valve;
and
wherein said high power density sorption heat store as a whole or at least in an area of said tube jacket is surrounded by an insulation.
