Modeling and Performance Prediction of an Adsorption Cooling System with Single Bed

Abstract

This article presents a mathematical model for simulating the thermal performance of a single bed zeolite-water adsorption cooling system. A set of energy balance equations for the system components have been solved using the Engineering Equation Solver (EES) program. An experimental test loop has been installed to prove the technical visibility of the system and validate the model. The variations in the temperature of the adsorption bed, condenser, and evaporator were investigated. The system coefficient of performance (COP) varied with the mass concentration ratio of the water vapor. The optimum COP reached a value of 0.39 at a minimum and maximum adsorbate concentration ratio of about 0.077 and 0.2, respectively. The maximum COP was achieved at a heating temperature of about 170 oC. The results of the model proved an acceptable compatibility with the experimental results thus the model can be considered as a valuable tool for researcher and engineers to design and simulate the performance of the adsorption cooling system.
