The invention relates to an arrangement which has an adsorption heat pump with at least one adsorber and at least one heat accumulator, having the following features: heat at different temperature levels can be stored in the heat accumulator (2) simultaneously; adsorption heat which is released during the adsorption and which is not to be utilized for later desorption can be dissipated to a heat sink and adsorption heat which is to be utilized for desorption can be stored in the heat accumulator at a temperature which is dependent on the adsorption temperature; desorption heat can at least partially be extracted from the heat accumulator at a desired temperature; a heat source, in particular a thermal solar collector, is provided, by means of which heat which is required for desorption can be provided at a temperature level which is higher than the temperature levels which can be reached in the heat accumulator (2) as a result of preceding desorption, and/or heat can be provided which is not present in the required quantity in the temperature accumulator. The invention also relates to an associated method for operating an adsorption heat pump.

The invention relates to an arrangement of heat exchangers (2) which are in thermal contact with an absorbent. Said heat exchangers can be cross-flown by a heat-exchanger fluid on the plate plane. Said arrangement comprises a plurality of heat exchanger plates which are arranged in an essentially parallel manner and a collector channel (1) in order to discharge the heat carrier fluid. The heat exchanger plates (2) comprise a metal foam structure or metal sponge structure on the external sides thereof.
