| 摘 要： | 空气载能辐射空调末端系统是近年来出现的一种以空气为载能媒介,孔板为末端的新型辐射末端系统.为了研究孔板末端的辐射传热特性,本文通过建立房间稳态传热模型,基于传热学基本理论,首先分析了以金属平板为辐射末端的顶板辐射空调系统中,顶板与各围护结构表面间不同温差下的辐射传热特性,并在此基础上进一步分析了空气载能辐射空调孔板末端的辐射传热问题,最终得到一个孔板辐射简化传热公式.通过实验验证,该方法具有足够的合理性和可靠性.

| Abstract: | In order to investigate the characteristics of the radiative heat transfer for the orifice plate, a steady model was established on the basis of the basic theory of radiative heat transfer. The radiative heat transfer for diverse temperature differences between the metal plate and enclosure surface was studied, and the radiative heat transfer for the orifice plate was analyzed. Finally, a new simplified equation of the radiative heat transfer of the orifice plate was found and proved to be reasonable and reliable with an experiment. |
