Ba(OH)2·8H2O계 자동차 축열시스템의 저장매체
Storage Media for the Vehicle Heat Storage System by Using Ba(OH)2·8H2O System
초록
본 연구는 Ba(OH)2·8H2O를 기본물질로 하는 안정된 자동차용 축열에너지시스템의 축열매체를 찾고 이의 적용가능성 여부를 조사하고자 한다. 실험은 순수한 Ba(OH)2·8H2O와 여기에 첨가제를 넣은 혼합물을 대상으로 장기간 사용가능성과 이들 물질이 cycle 반복후 상태의 변화와 열적특성에 대해 조사되었다. 연구의 결과는 Ba(OH)2·8H2O에 Sr(OH)2·8H2O를 첨가한 혼합물이 1300회 cycle 반복후 질의 변화가 없었으며 방열량 감소율도 2%로서 자동차용 축열시스템의 축열매체로서의 가능성이 높게 나타났다.
This study was investigated to find storage material of thermal energy storage system for a vehicle with the basic material of Ba(OH)2·8H2O and to test a feasibility of it. Experiment was investigated usability for long time and state change and thermal property after cycle with Ba(OH)2·8H2O and misxture doping additive to it. The result of this research indicated the mixture adding Sr(OH)2·8H2O to Ba(OH)2·8H2O have high feasibility as storage material for thermal energy storage system. This mixture did not exhibit the state change during 1300 cycles and the rate of decrease of heat realese energy was about 2%, relatively low value.
