Development of Open-type Adsorption Thermal Storage Heat Pump System Applying HAS-Clay

Part 1-Experimental Results of Small Equipment and Calculation Model of Adsorption Thermal Storage Tank

Abstract

We developed the open-cycle type adsorption thermal storage system with high density heat storage and no heat loss (no heat storage loss) related to the temperature with the outside air. Based on adsorbent of the HAS-Clay that have been developed by the National Institute of Advanced Industrial Science and Technology (AIST), this thermal storage system can utilize the low-temperature waste heat. Characteristics of charging and discharging operation were studied experimentally about the packed bed of HAS-Clay. In this paper, first, the features of adsorption thermal storage technology and the developed thermal storage material (Granulated HAS-Clay) are described. Second, the characteristics of charging and discharging operation is introduced by the experimental data. Last, the simulation model of adsorption thermal storage tank is explained though the comparison of calculation result and experimental result on the charging and discharging operations.
