Abstract: The energy crisis demands immediate action and allows adsorption technology to replace conventional systems, as adsorption technology is a sustainable and eco-friendly process that doesn't add to the problem of global warming or cause ozone depletion. Adsorption cooling systems have recently gained significant attention in research. Natural zeolites are found worldwide, and their variety allows one to choose and modify many material properties, including adsorption capacity, pore size, polarity, and surface area, according to specific application demands. Adsorbents' behavior concerning equilibrium adsorption isotherms and kinetics determine an adsorption system's efficacy. The adsorbent material's hydrophobicity is essential in determining the amount of water vapor and temperature required for ad/de-sorption cycles. It is evident from the adsorption isotherm pattern, which underlines its significance. The unique S-shaped adsorption isotherm of zeolites makes them promising adsorbent materials for many adsorption systems. Zeolites have a significant specific surface area, and their microporous structure enables higher adsorption capacities. An assessment of various cycle designs to boost the efficiency of adsorption cooling systems by considering the effect of different design and operating factors has been concluded. This paper reviewed the research on Zeolite-water adsorption technology, cooling systems, heat pumps, desalination systems, and more. The developments of Zeolite-water working pair, including adsorption capacity improvement (composites), adsorption isotherms, heat-mass transfer enhancement, cycle designs, numerical simulation work, and some practical applications for energy efficient systems, were conferred.
