On scope of improving solid sorption cooling—generating it continuously in a regenerative single adsorbent column

Abstract

An experimental study relating generation of continuous solid sorption cooling in a single adsorbent tube is described in this article. Quick periodic pressurization and depressurization of an adsorbent column generates differential cooling between the two ends of the column. Based on a critical review of previous research findings, however, few modifications have been found necessary in the existing process design. Experiments conducted earlier have indicated that significant cooling is available within activated carbon inside the bed. To retrieve this cooling, the system has been modified to a regenerative-type cooling cycle. On the basis of theoretical recommendation, a carbon dioxide-activated carbon pair has been chosen for the present study, aiming at cooling for nearly room temperature applications. Results not only indicate noticeable improvement from its previous design, they seem to be quite promising.
