Porous coordination polymers (PCPs)/metal-organic frameworks (MOFs) are inorganic-organic hybrid materials with a permanent three-dimensional porous metal-ligand network. PCPs or MOFs are inorganic-organic analogs of zeolites in terms of porosity and reversible guest exchange properties. Microporous water-stable PCPs with high water uptake capacity are gaining attention for low temperature heat transformation applications in thermally driven adsorption chillers (TDCs) or adsorption heat pumps (AHPs). TDCs or AHPs are an alternative to traditional air conditioners or heat pumps operating on electricity or fossil fuels. By using solar or waste heat as the operating energy TDCs or AHPs can significantly help to minimize primary energy consumption and greenhouse gas emissions generated by industrial or domestic heating and cooling processes. TDCs and AHPs are based on the evaporation and consecutive adsorption of coolant liquids, preferably water, under specific conditions. The process is driven and controlled by the microporosity and hydrophilicity of the employed sorption material. Here we summarize the current investigations, developments and possibilities of PCPs/MOFs for use in low-temperature heat transformation applications as alternative materials for the traditional inorganic porous substances like silica gel, aluminophosphates or zeolites.
多孔配位聚合物（PCPs）/金属有机框架（MOFs）是具有永久性三维多孔金属-配体网络的无机-有机杂化材料。就孔隙率和可逆客体交换特性而言，PCPs或MOFs是沸石的无机-有机类似物。具有高吸水能力的微孔水稳定PCPs因在热驱动吸附式制冷机（TDCs）或吸附式热泵（AHPs）的低温热转换应用中受到关注。TDCs或AHPs是传统以电力或化石燃料运行的空调或热泵的替代品。通过使用太阳能或废热作为运行能源，TDCs或AHPs可以显著帮助减少工业或家庭供热和制冷过程产生的一次能源消耗和温室气体排放。TDCs和AHPs基于冷却剂液体（最好是水）在特定条件下的蒸发和连续吸附。该过程由所用吸附材料的微孔率和亲水性驱动和控制。在此，我们总结了PCPs/MOFs作为传统无机多孔物质（如硅胶、磷酸铝或沸石）的替代材料在低温热转换应用中的当前研究、进展和可能性。
