Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
147 words
Adsorption apparatus for use as electro-heat storage by using the heat pumping effect, comprising: an adsorption substance container containing an adsorption substance, said adsorption substance being capable of adsorbing water and being heatable by an electric heating system as to desorb steam from said adsorption substance; a condenser for liquifying said steam to form a condensate; a collecting container for collecting said condensate, said adsorption substance container being in vapor communication with said collecting container by a steam line, said condenser being in vapor communication with said collecting container so that desorbed steam from said adsorption substance can be liquified by said condenser to form said condensate and said condensate collects in said collecting container; a heat collector for collecting ambient heat; a water cycle connected between said collecting container and said heat collector; and a circulation pump installed in said water cycle for circulating said condensate.
Claim 2
Dependent Claim
147 words
Adsorption apparatus for use as electro-heat storage by using the heat pumping effect, comprising: an adsorption substance container containing an adsorption substance, said adsorption substance being capable of adsorbing water and being heatable by an electric heating system as to desorb steam from said adsorption substance; a condenser for liquifying said steam to form a condensate; a collecting container for collecting said condensate, said adsorption substance container being in vapor communication with said collecting container by a steam line, said condenser being in vapor communication with said collecting container so that desorbed steam from said adsorption substance can be liquified by said condenser to form said condensate and said condensate collects in said collecting container; a heat collector for collecting ambient heat; a water cycle connected between said collecting container and said heat collector; and a circulation pump installed in said water cycle for circulating said condensate.
Claim 3
Dependent Claim
33 words
Adsorption apparatus in accordance with claim 1 wherein said apparatus further comprises, a control device for comparing the temperature of said heat collector with the temperature of said condensate in said collecting container.
Claim 4
Dependent Claim
27 words
Adsorption apparatus in accordance with claim 1 wherein zeolite selected fro the group consisting of type Na-A, Mg-A, Na-Y, H-Y and Na-X is used as adsorption substance.
Claim 5
Dependent Claim
23 words
Adsorption apparatus in accordance with claim 1 wherein an additional electrical heating unit is installed in the lower part of said collecting container.
Claim 6
Dependent Claim
25 words
Adsorption apparatus in accordance with claim 1 wherein an antifreeze agent having a low boiling point is admixed with the water in said water cycle.
Claim 7
Dependent Claim
45 words
Adsorption apparatus in accordance with claim 1 wherein the lines of said water cycle are slightly bendable at certain segments, so that position changes are made possible during the installation of the heating collector with respect to the collecting container without opening said water cycle.
Claim 8
Dependent Claim
47 words
Adsorption apparatus in accordance with claim 1 wherein said heat collector is positioned higher than the maximum water level in said collecting container, so that the water in said heat collector can run from said heat collector back into said collecting container under the force of gravity.
Claim 9
Dependent Claim
31 words
Adsorption apparatus in accordance with claim 1 wherein the lines of said water cycle extend through an insulation element which closes the installation opening for the installation of said heat collector.
Claim 10
Dependent Claim
26 words
Adsorption apparatus in accordance with claim 8 wherein a ventilation system is integrated in said insulation element which feeds hot exhaust air to said heat collector.
Claim 11
Dependent Claim
41 words
Adsorption apparatus in accordance with claim 1 wherein the water level in said collecting container is dimensioned sufficiently large that the latent heat which is released during icing is sufficient to replace the heat amount which said heat collector cannot feed.
