Abstract
From the view points of energy saving and environmental impact, we have been studying Chemical heat pumps (CHP) especially focusing on using calcium systems. The CaO/H_2O/Ca(OH)_2 gas-solid reversible hydration/dehydration reaction is used to store and release hot/cold heat. In this study, we propose novel Cold Storage Vehicles using waste heat such as exhaust heat from the engine for energy source of the chemical heat storage/pump. It is shown that the chemical heat pump can be used for high-density heat storage of the waste heat and used for cooling and heating the vehicle space.
