Steady state thermodynamic differential analysis is developed for the adsorption-based cooling systems. The introduced thermodynamic model represents the behaviour of adsorption cooling systems, based on a precise, reasonable, and clear fundamental approach. The energy conservation principle is used to analyze components and processes in the system. The dynamics of adsorption is expressed using Dubinin-Astakhov adsorption equilibrium model. Energy interactions are evaluated to determine the theoretical performance and the operating parameters of the system. The effect of pressure and temperature on the adsorption/desorption capacity of silica gel is presented as candidate. The case studied developed reports cooling system build using Silica gel-water as the working pair. Keywords: Sorption Cooling, Silica gel, energy balance, thermal cooling
