| 采用漫射封闭腔内非灰谱带模型，并结合玻璃吸收和透射的性质，对Low-E玻璃镀膜侧表面的热辐射特性进行了数值模拟研究。结果表明：在相同条件下，Low-E玻璃与普通透明玻璃所受到的辐射热流量相差很大。同时利用模型考察了玻璃温度，加热管湿度以及玻璃透射率对Low-E玻璃辐射换热的影响。 |

| Abstract: |
| As the thermal radiation of coating surface on Low E glass is strongly influenced by its spectrum, the nongray band model in diffusing enclosure was used to numerically simulate the surface radiative characteristics of Low E glass in combination with the glass properties of absorptivity and transmissivity. The results show that the value of recieved radiative heat flux between Low E glass and clear glass differs a lot under same condition. The model also shows the effects of glass temperature, heating tube temperature and glass transmissivity on radiative heat transfer of Low E glass. |
