Floor heating systems have been used since ancient times due to their advantages over other heating systems. Previous studies are mainly on the floor heating systems using hot water. There is insufficient study, to the author's knowledge, about floor heating systems using electric heating cords. In the thesis, the heat-transfer characteristics and comfort for the floor heating system and ceiling panel heating system using electric heating cords were investigated.

地板辐射采暖系统与其它采暖方式相比，因许多优点它已有多年的使用和发展历史，在相关研究文献中，大都采用低温热水地板辐射采暖为研究对象，相对而言，电热地板辐射采暖系统的研究文献比较欠缺，为此，本文研究了电热地板辐射采暖和顶棚辐射采暖两种形式下的传热特性和室内热舒适性。
