Comparative analysis of Silica-gel/Water and Zeolite/water Pair on adsorption Refrigeration System

Abstract

Abstract The current work presents a comparative investigation on the execution of closed cycle adsorption refrigeration systems with Zeolite as adsorbent and water as adsorbet in one system and silica-gel as adsorbent and water as adsorbate in another system. In the present analysis, the effect of variation of the regeneration temperature on the coefficient of performance (COP) along with specific cooling power (SCP) for both the pairs has been studied and compared. From the analysis, it was found that specific cooling power (SCP) and coefficient of performance (COP) for Zeolite/water pair are better at a lower range of regeneration temperature while it is not that good for silica-gel/water pair. Both the pairs perform well at higher regeneration temperature. This being a theoretical study the results may vary practically.
