Abstract:
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.
