Performance Prediction of Adsorption Cooling System using Spherical Activated Carbons and Ethanol

Abstract

We have developed an innovative spherical activated carbon (SAC) for adsorption heat pump application. It was observed that the SAC had a large effective adsorption compared with conventional activated carbons against ethanol. To predict the system performance with SAC as adsorbent of adsorption heat pumps, a dynamic simulation model based on the heat exchanger characteristics estimation was performed. The simulation results revealed that the adsorption cooling system with the SAC achieved a larger cooling capacity compared with the conventional activated carbon powder-ethanol pair, and the COP at the optimum cycle time was improved by 12% by the SAC-ethanol pair.
