摘　　要：针对我国公用建筑高能耗的现状,以提高能源利用率,实现建筑节能减排为目的,提出了在大空间高能耗建筑上应用U型布置地板辐射采暖系统。此采暖系统在民用建筑的应用已非常广泛,但在大空间公用建筑上还有待进一步推广普及。对U型低温地板辐射采暖系统的传热机理进行了全面分析,对相关模型进行了较为详细的模拟,为地板辐射采暖技术的推广及工程应用提供了很好的理论依据。In view of the situation of Chinese public buildings had high energy consumption, in order to improve the energy utilization efficiency, and to reduce the emissions , we give the idea of using U-shaped radiant floor heating system on the buildings which consume a large amount of energy. This heating system has been widely applied in residential construction. But in public buildings it remains to be further popularization. The heat transfer mechanism of U-shaped radiant floor heating system is fully analyzed in this paper. And more detailed simulation has been carried out. And this paper provides a reliable theoretical basis for the radiant floor heating technology＇ s promotion and the specific implementation of engineering.
