Abstract
The authors have already proposed a chemical heat pump using CaO/H_2O/Ca(OH)_2 reaction dryer (CHPD) for energy saved drying and confirmed that the CHPD unit produce hot dry air effectively in the heat-release step. In this paper, we examined the condensation heat utilization of the decomposed water vapor in the high temperature chemical heat-storage step to Ca(OH)_2 reactant bed. The results show that the refined CHPD system including the condensation heat utilization enhances the efficiency of drying process especially from the viewpoint of exergy.
