未利用熱エネルギー有効活用のための吸着式ヒートポンプ

抄録

Unused thermal energy such as waste thermal energy from industrial processes is due to low temperature level and unstable output. For the effective utilization of the unused thermal energy, thermal energy storage, in particular chemical heat storage is a key technology. In this review, a novel adsorption heat pump, which is one of the chemical heat storage, is introduced. This system adopts a direct heat exchange method to the adsorption heat pump to increase heat transfer rate between adsorbent and heat transfer fluid. Basic operation and the methods to improve the efficiency of the heat pump system are explained.
