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

Part 5-Demonstration Test of Off-line Heat Transport System

Abstract

We developed an open-cycle type adsorbent thermal storage system with HAS-Clay to utilize low-temperature waste heat. The demonstration tests were performed no a stationary type and an offline heat transportation type after the development of systems and materials, such as the durability of HAS-Clay. In the offline heat transportation type, the thermal storage tank charged in the co-generation system was transported by the tractor-trailer and used to heat up water and air in a swimming center. It was evaluated as an absorption-based heat storage system through three seasons: summer, interphase, and winter. The test data indicated a regenerating efficiency of 90% or more. The charge/discharge characteristics of the system were also evaluated. In addition, by comparing the test data with the numerical analysis model on the charge/discharge operations, it was confirmed that the numerical analysis model can be used as a design tool.
