Beschreibungen/Notizen

• Cyclic physical adsorption and desorption processes on porous materials can be used for the conversion of heat in heat transformation processes, which is the working principle in adsorption heat pumps (AHPs). Environmentally benign water with its high enthalpy of evaporation is the working fluid of choice in AHPs. Metal‐organic frameworks, MOFs can adsorb large amounts of water or methanol, up to their own weight. MOFs could be alternative materials to silica gels, zeolites, or aluminum phosphates for low‐temperature heat transformations in AHPs. Microporous and water‐stable MOFs with high water‐uptake capacity are gaining attention for low‐temperature heat transformation applications in adsorption heat pumps as an alternative to traditional air conditioners or heat pumps operating on electricity. AHPs are based on the evaporation and consecutive adsorption of coolant liquids, preferably water, in a porous material under specific conditions. By using waste heat as the operating energy AHPs can significantly help to minimize primary energy consumption.
