摘要:
辐射供冷空调系统具有舒适、节能等优点,备受国内外工程设计和研究者的关注。在此通过实验研究了顶棚辐射供冷房间在冷吊顶辐射作用下,室内空气温度、房间壁面温度、人体表面温度的变化规律。在此基础上,分析了人体与环境的对流换热及辐射换热的变化规律。研究结果表明,在辐射供冷系统开启后约60min内,辐射板表面温度、室内空气温度有显著变化,人体服装外表面温度变化比较缓慢,人体和环境的对流及辐射换热量逐步增大,系统开启60min后,上述各项趋于稳定。

Abstract:
Radiant panel cooing system has attracted a great concern in engineering design and research due to its advantages of comfort and energy saving. This article studies the variations of indoor air temperature, room wall temperature, human body surface temperature in ceiling cooling room by experiment. The variation roles of convection and radiation heat transfer between human body and the environment at ceiling cooling room are analyzed. The results show that, in the 60 minutes operation of the radiant cooling system, the radiant panel surface temperature, indoor air temperature change significantly, the human garment temperature changes slowly, the convection and radiation heat transfer between human body and the environment increase gradually; after 60 minutes operation of the radiant cooling system, all of the above mentioned tend to be steady.
Key words:  pyrology  ceiling radiant cooling  surface temperature  convection heat transfer  radiation heat transfer
