Outline of Final Research Achievements

This study aimed to clarify the simultaneous heat and mass transfer behavior in an adsorbent desiccant rotor for the effective use of the low temperature exhaust heat.
Influences of the pore size distribution on the dehumidifying performance and the adsorption/desorption behavior of the adsorbent desiccant rotor was experimentally investigated. Air temperature distribution in the adsorbent desiccant rotor was also measured and interpretation of the temperature distributions was carried out. Furthermore, time variations of the weight of a small piece of desiccant rotor measured at various adsorption / desorption time and their duration time ratio were discussed. Numerical computation in consideration of these results indicates good agreement with experiments.
Temperature increase of wasted steam by using adsorption heat was investigated as an extended application of the desiccant materials. By employing A-type silica gel, continuous temperature increase operation is possibly achieved.
