Adsorption-based heat transformation systems are studied from the twentieth century; however, their performance is low to replace conventional systems. Metal-organic frameworks (MOFs) are providing a new class of micro- and nano-porous organic adsorbents. These have adjustable geometry/topology with a large surface area and pore volume. A comparison of the coefficient of performance (COP) between the MOFs and conventional adsorbents-based cooling systems is made for the years 1975–2020. Conventional adsorbents achieve COP of 0.85, whereas it is improved to 2.00 in the case of MOFs. The main bottleneck in the lower COP level is the low adsorption equilibrium amount. This study is aimed to provide comprehensive detail of water-vapor adsorption equilibrium and physicochemical properties of hydrophilic MOFs. Zn based MOFs are not stable in the presence of water-vapors, whereas MIL series, Zr, Ni, and Cu based MOFs are relatively more stable. Among the studied MOFs, MIL-101(Cr) possesses the highest adsorption uptake of 1.45 kg/kg at 25 °C (saturation condition) and outperformed for heat transformation applications. Its uptake can be increased to 1.60 kg/kg by coating with graphite oxide. For water desalination, MIL-53(Al) exhibits specific daily water production of 25.5 m³/ton.day (maximum) with a specific cooling power of 789.4 W/kg. Both MIL adsorbents are found promising which can be considered for various adsorption applications.

从二十世纪开始研究基于吸附的热转化系统。但是，它们的性能不足以替代常规系统。金属有机框架（MOF）正在提供一类新型的微孔和纳米孔有机吸附剂。这些具有可调节的几何形状/拓扑结构，具有较大的表面积和孔体积。比较了1975年至2020年MOF与传统的基于吸附剂的冷却系统之间的性能系数（COP）。常规吸附剂的COP达到0.85，而对于MOF则提高到2.00。较低COP水平的主要瓶颈是吸附平衡量低。这项研究旨在提供亲水性MOF的水蒸气吸附平衡和理化特性的详细信息。锌基MOF在存在水蒸气的情况下不稳定，而MIL系列，Zr，Ni和Cu基MOF相对更稳定。在已研究的MOF中，MIL-101（Cr）在25°C（饱和条件）下具有1.45 kg / kg的最高吸收率，并且在热转化应用中表现出色。通过涂上氧化石墨可以将其吸收增加到1.60 kg / kg。对于海水淡化，MIL-53（Al）的特定日产水量为25.5 m³ /吨。天（最大），比制冷能力为789.4 W / kg。发现两种MIL吸附剂都有希望，可以考虑用于各种吸附应用。
