Patent ID: 8707729

Claim:
An adsorption heat pump or adsorption refrigerator, comprising: at least one adsorber element having a stable shape; an evaporator; a condenser; and a vacuum-tight adsorbate channel connected to the adsorber element, the evaporator and the condenser through connections; the at least one adsorber element comprising: a heat-conducting solid body and a sorption material for a vaporous adsorbate, said sorption material being arranged on an outer surface of the heat-conducting solid body; a fluid-tight composite film being connected flat to the heat-conducting solid body at least in areas of the outer surface of the heat-conducting solid body in contact with a heat transfer fluid; said fluid-tight composite film being connected to the heat-conducting solid body positively, non-positively, or by adhesive force; said fluid-tight composite film comprising at least one first layer, said first layer being a metal layer and/or a layer of a heat-conducting material oriented perpendicular to the layer; and said fluid-tight composite film further comprising at least one second layer, said second layer being a sealing layer or a supporting layer; said at least one adsorber element being structured and arranged so that heat exchange, between the heat transfer fluid and at least one of the following two, can take place via the fluid-tight composite film: the heat-conducting solid body and the sorption material arranged thereon.
