The invention relates to an adsorber element for a heat exchanger and an adsorption heat pump or adsorption refrigerator that contains at least one such adsorber element. The adsorber element includes a heat-conducting solid body and a sorption material for a vaporous adsorbate arranged on the surface of this solid body. A fluid-tight foil composite is arranged on the outer surface of the open-pore solid body, at least in the areas in which a contact with a heat transfer fluid is provided, wherein this adsorber element is embodied such that the heat exchange between the open-pore solid body and the heat transfer fluid can take place via the fluid-tight foil composite.

Adsorption heat pump, adsorption refrigerator and adsorber elements therefor

System including an adsorption heat pump with at least one adsorber and at least one heat accumulator and method for operating an adsorption heat pump. The system additionally includes a heat source configured to provide heat for a desorption at a temperature that is at least one of higher than temperature levels achievable through previous adsorption cycles in the at least one heat accumulator and not available in a predetermined quantity in the at least one heat accumulator. The at least one heat accumulator is structured and arranged to simultaneously store heat at different temperature levels therein. Adsorption heat released during an adsorption, which is not to be used for a later desorption, is dissipated to a heat sink. Adsorption heat to be used for the later desorption is stored in the heat accumulator at a temperature dependent on an adsorption temperature. Desorption heat is extractable at least in part from the at least one heat accumulator at a desired temperature.

Adsorption heat pump with heat accumulator

The invention relates to a method for production of a zeolite layer on a substrate containing metal, comprising the following method steps: production of an aqueous suspension, comprising several components, one component comprises at least one cross-linking element from the third, fourth or fifth main group of the periodic table, the substrate containing metal comprises at least one of the cross-linking elements, introduction of the substrate containing metal to the aqueous suspension, heating the aqueous suspension and the substrate containing the metal present therein for the in-situ crystallisation of a zeolite layer on the substrate containing metal, whereby the cross-linking elements in the substrate containing metal are extracted and included in the zeolite layer, a cross-linking element present in the suspension for formation of the zeolite layer is present at a concentration so low that a crystallisation in the suspension is largely or completely avoided and said element is principally provided by the substrate.
