Water vapor adsorption isotherm taxonomy of silica-gel based type-linear (fictitious), and four adsorbents enabling type-I, II, III, and V isotherms by means of International Union of Pure and Applied Chemistry (IUPAC) classification, are studied for desiccant air-conditioning (AC) applications. Ideal temperature and humidity zones for various AC applications are drawn on psychometric charts. Published adsorption data for studied adsorbents are fitted with the appropriate adsorption models. Ideal desiccant AC cycle is evaluated for AC applications and steady-state cycled moisture is estimated by means of adsorption isobars. Type-linear adsorption isotherm gives the maximum steady-state dehumidification performance for AC in industrial processes of matches manufacturing/drying/storage, rubber dipped goods storage, and photo studio drying room. However, adsorbents enabling type-V isotherm are found the optimum adsorbents for tobacco stemming/stripping/softening and optical lenses grinding. For industrial process–dipped surgical articles; adsorbents enabling type-I, type-II, and type-linear isotherms are resulted the optimum adsorbents under conditions of low (< 68°C), medium (68°C-87°C), and high (> 87°C) temperature regeneration, respectively.
