Abstract

본 연구에서는 비정질 강섬유 혼입 바닥몰탈을 이용한 바닥난방시스템과 일반 몰탈을 사용한 바닥난방시스템의 열성능을 비교 평가하기 위하여 시뮬레이션을 실시하였다. 시뮬레이션은 온수공급온도를 변화시켰으며 다음과 같은 결론을 얻었다. 바닥의 표면온도, 실내의 공기온도 등을 검토 결과 강섬유온돌을 사용할 경우에는 실내공기를 기준으로 하면 강섬유온돌이 일반온돌에 비해 7~9%에 가까운 열효율이 상승되었으며, 바닥의 온도를 기준으로 하면 2~4% 온도상승이 일어나는 것으로 나타났다. The thermal performance of amorphous steel fibers mixed floor heating system was evaluated. Analysis of results, depending on the hot water supply temperature changes, the average temperature of the bottom of the hot water supply temperature is an amorphous steel fiber floor heating system is about 2~4% higher. The average temperature of the floor surface to 1.5m air amorphous steel fiber system is 1~2% higher. The amount of heat supplied to indoor air (1.5m) from the bottom surface of amorphous steel fiber floor heating system is about 7~8% higher
