“…The basic adsorption cooling system (ACS) works like vapor compression refrigeration, with the difference being replacing mechanical compression with thermal compression. It comprises four main components: evaporator, adsorbent (one or multiple beds), condenser, and expansion valve (Figure right). , The theory behind it is illustrated on the Clausius–Clapeyron diagram (Figure left). It consists of isosteric heat of adsorption (1 → 2), isobaric heating and desorption (2 → 3), isosteric cooling (3 → 4), and isobaric cooling and adsorption (4 → 1).…”

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.

Summary Adsorption technology is very attractive for producing desalinated water and cooling with no harmful impact on the environment. The performance of adsorption water applications (desalination and cooling) depends on the adsorption characteristics. Many adsorption systems designs were investigated worldwide, employing different adsorbent materials to develop a cost‐effective and high‐performance system. This review presents and summarizes the studies in adsorption and the corresponding applications in desalination and cooling and compares the adsorption properties of composite adsorbents. The review focuses on the composite materials and how they were synthesized while comparing them in terms of the amount of adsorption. The reviewed materials have been classified according to the basic host, such as silica gel, zeolite, carbon, metal‐organic frameworks (MOF), and vermiculite. The review contains more than 70 composites. The maximum reached water vapor uptake is 1.92 kg/kg of PHTS/CaCl2‐20 wt% composite at 0.9 P/Ps. The highest available desorption amount is 1.48 kg/kg of MOF composite for desalination applications and 0.87 kg/kg of vermiculite composite for cooling applications.

“…Two main reasons why adsorption was chosen to replace the conventional air-conditioning system are energy shortages and climate change caused by depletion [5]. In 1992, at the Earth Summit (Rio de Janeiro), it was discussed how to reduce fossil fuels whilst in the Montreal Protocol in 1987, the protection of the ozone layer and substances that are responsible for its depreciation was discussed [6]. Adsorption refrigeration and heat pump technology are one way to solve it because they could meet the needs since it requires little electricity, and the refrigerants for this technology are the substances of water, ammonia, alcohol, and so on which are green refrigerants with zero ODP (Ozone depletion potential) and zero GWP (Greenhouse warming potential) [7].…”

Adsorption Cooling System gives an alternative to the commercial vapor compression refrigeration cycles due to their benefits of having a very environmentally friendly and promising energy-saving system. An adsorption cooling system consists of four main components which are thecondenser, evaporator, expansion valve, and adsorption bed for the system to effectively function. One of the factors that affect the efficiency of the system is the performance of the evaporator itself as the system operates at sub-atmospheric pressure and the performance is mediocre when using conventional evaporators. Due to the low-pressure condition, hydrostatic pressure may affect the saturated temperature of the water refrigerant in a flooded type evaporator. Therefore, in this study, the performance of the evaporator was investigated based on the water height variation. The highest heat transfer coefficient and evaporation heat transfer rate are achieved when the water is set at the heat exchanger tube diameter level. Furthermore, 0.1 kg of silica gel adsorbent is used to obtain the maximum of 250 W/kg of Specific Cooling Power when the heat transfer fluid is set to 20 ºC.
