“…Compared to AQSOA serials, the SAPO-34–water pair also showcases feasibility in adsorption cooling by integration with metal foam or a heat exchanger via a coating methodology to enhance the mass transfer and energy recovery. ,, Other zeolite-based sorbents, like ALPO-18, SWS-1L, zeolite 13X, and APO-Tric, have also been reported for adsorption chiller applications. − However, key limitations such as low adsorption capacities and therefore low working capacity and the high Δ T lift of the zeolite–water pair have yet to be solved due to nonflexible modulations of the zeolite structure, making less progress in improvements of the COP and SCE.…”

The energy demand for traditional vapor-compressed technology for space cooling continues to soar year after year due to global warming and the increasing human population's need to improve living and working conditions. Thus, there is a growing demand for eco-friendly technologies that use sustainable or waste energy resources. This review discusses the properties of various refrigerants used for adsorption cooling applications followed by a brief discussion on the thermodynamic cycle. Next, sorbents traditionally used for cooling are reviewed to emphasize the need for advanced capture materials with superior properties to improve refrigerant sorption. The remainder of the review focus on studies using engineered nanoporous frameworks (ENFs) with various refrigerants for adsorption cooling applications. The effects of the various factors that play a role in ENF−refrigerant pair selection, including pore structure/ dimension/shape, morphology, open-metal sites, pore chemistry and possible presence of defects, are reviewed. Next, in-depth insights into the sorbent−refrigerant interaction, and pore filling mechanism gained through a combination of characterization techniques and computational modeling are discussed. Finally, we outline the challenges and opportunities related to using ENFs for adsorption cooling applications and provide our views on the future of this technology.

“…In general, the S-shaped water sorption isotherms observed for AlPOs and SAPOs make the adsorbents suitable materials for heat transformation applications. This can be exemplified by the recent work of Kim et al . who synthesized an AlPO 4 (CHA structure) and SAPO 4 (Si/Al of 0.5) and tested their water sorption behaviors.…”

In recent years, the deployment of chemically stable physisorbents in various water sorption-related applications has received significant attention. Depending on their structural features, different types of porous sorbents manifest distinct shapes of water sorption isotherms. The translation of water sorption profiles of adsorbents into appropriate practical applications is yet to be established. This Review gives an overview of the water adsorption studies conducted on different hydrolytically stable porous solids selected from different classes of solid-state materials (organic, inorganic, and hybrid materials). Brief analyses of the water sorption behavior and the relations to materials' intrinsic structural features are made. Based on adsorbents' observed water sorption characteristics, the prospects of their practical/commercial deployment in chosen sectors are also commented. The criteria for using porous adsorbents in specific water-related technologies, which can help guide the design and assembly of suitable water adsorbents, are also reviewed. In addition, the challenges that need to be overcome in developing efficient water vapor adsorbents for a given application are also discussed.

A dynamic model is presented for a chiller working with a composite adsorbent (silica activated carbon/CaCl 2 )water pair in a solar-biomass cooling installation. The main objective is determining a link between two possible evaporator configurations and the refrigerator's performances. The two considered evaporators work at different pressure levels. The related time evolution profiles of temperature, pressure and water content are studied. Moreover, the effects of hot water inlet temperature and cooling water inlet temperature on the specific cooling capacity (SCP) and coefficient of performance (COP) are predicted by means of numerical simulations. The results show that an increase in the temperature of hot water and a decrease in the temperature of the cooling water allow an increase in COP and SCP. In particular, for a hot water inlet temperature of 85°C and a cooling water inlet temperature of 40°C, the COP and Qev are 0.67 and 4.3 kW, respectively.
