Abstract
In order to save energy and decrease environmental impacts of thermal energy utilization systems, a CaO/H_2O/Ca(OH)_2 chemical heat pump (CHP) can be applied for the systems by using the high-density heat storage and cooling/heating functions of the CHP. In this paper, the performance of the CHP for refrigeration and air-conditioning were examined based on the authors' experimental and theoretical over ten years studies on CaO/H_2O/Ca(OH)_2 CHPs. As a result, the CaO/H_2O/Ca(OH)_2 CHPs are found to work more efficiently than other heat pump systems in appropriate heat source conditions.
