溫水 溫突 바닥 構造體의 熱傳達 解析과 實驗 硏究

"Ondol" have been used in residential buildings for several thousands years in Korea. The traditional "Ondol" heating system of Korea has changed into the radiant heating system with piping embedded in floors or slabs. This study reports the results of transient experiments performed on a radiant heating system and enclosure. The paper presents some details of the thermal response of slab-heated buildings to varying patterns of heat input. Furthermore, I'll compare the results of experimentation with the ones of the numerical simulation by using the explicit and implicit forms of the finite difference methods (FDM). The study has contributed to testify the feasibility of numerical analysis, and the understanding of the transient behavior of radiant heating panels and enclosure exposed to this type of heating system.
