Experimental study on water vapor sorption performance of metal organic frameworks and their application potential for indoor air dehumidification
This study investigates the water vapor sorption performance of five metal organic framework materials (MIL-101(Cr), MIL-100(Fe), aluminum fumarate, MOF-303(Al), PCN-333(Al)) for indoor environment humidity control through experiment measurements, aims to identify materials that enhance water vapor adsorption capacity and allow for low temperature regeneration. The results show that MIL-101(Cr) exhibits highest water vapor adsorption capacity which is 3.5 to 6 times of conventional desiccant materials. The adsorption isotherm of MIL-101(Cr) exhibits an "S" type change, with a steep point between 30 % and 60 % RH which falls within the indoor thermal comfortable range. The experiment results also show that MIL-101(Cr) is nearly completely desorbed at relative humidity of 20 %, indicating its potential for low-temperature regeneration. Based on its strong water vapor sorption performance, the green and low-cost synthesis method will be the key for its utilization to improve the efficiency of solid desiccant air conditioning system.
期刊介绍：
The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling.
As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews.
Papers are published in either English or French with the IIR news section in both languages.
