Abstract
Aiming at solution of the problem that the heat exchange speed of zeolite heat pump is slow, the time which 1 cycle takes is long, direct contact type particle packed bed's performance were examined focusing zeolite particle layer height. The findings by as a result making zeolite particle layer height high of there having been without time influence to saturation adsorption temperature, having more influence on the quantity of heat used for desorption per unit mass of the zeolite in a test section downstream site was acquired. As a result ,we found out that the direct contact heat exchanger had the advantage of making a particle layer thin.
