中文摘要：

近年地板辐射采暖运行时多出现房间过热情况,有悖于节能的设计理论。本文对地板结构层内的传热过程进行节能方法分析,分析结果表明选择较高的供回水温差、优先选择低的室内设计温度、适当增加加热管管间距可降低初投自且节约系统能耗。

英文摘要：

With the improving thermal insulation performance of building envelope, the rooms are often overheated with the heating system designed by the manual in recent years. It was against with save energy. The energy-saving heat transfer of the radiant floor heating system was studied theoretically. The results show that the higher supply and return water temperature has lower indoor design temperature,the greater tube spacing are helpful for decreasing the local overheating and saving pipes.
