Abstract

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.
