ENHANCEMENT OF GENERATION OF HIGH-TEMPERATURE STEAM FROM A NOVEL ADSORPTION HEAT PUMP ASSISTED BY THERMAL ENERGY STORAGE MATERIAL

摘要

Enhancement of generation of high-temperature steam using a novel adsorption heat pump is investigated. Inrnthis study, enhancement of the preheating process by the use of thermal energy storage material wasrninvestigated. The effect of the heat capacity of adsorbent on the mass of steam generated was theoreticallyrninvestigated. As a result, while the mass of water vapor adsorbed during the preheating was increased withrnthe heat capacity of the adsorbent, the temperature after the preheating process decreased. It was found thatrnthere was the maximum value in the mass of steam generated. In the experiment, an additive was inserted asrnthe thermal energy storage material to increase the heat capacity of adsorbent. When the overall heat capacityrnof the packed bed of the adsorbent was increased by 18% by using the additive, the mass of steam generatedrnper unit mass of the adsorbent was increased by 25%.
