DERIVATION OF EXHAUST HEAT UTILIZATION CONDITIONS FOR DESICCANT SYSTEM REGENERATED BY WASTE HEAT FROM HOME-USE SOLID OXIDE FUEL CELL COGENERATION SYSTEM

This study aims to develop a system that utilizes waste heat from a home-use solid oxide fuel cell (SOFC) in a desiccant system to achieve efficient energy use and a healthy indoor environment. First, SOFC operation will be tested in a demonstration house from intermediate to summer periods, gathering data around the hot water storage tank that accumulates waste heat. This data will be used to identify optimal operating conditions that minimize heat loss. Based on these results, experiments in an environmental test chamber will determine the best conditions for maximizing the desiccant’s dehumidification capacity using waste heat.
