| 摘 要： | 在建立传热模型的基础上,系统研究了反射隔热涂料的太阳能反射率和辐射率对建筑物表面温度和室内温度的影响。计算表明,在给定的条件下,反射隔热涂料相对于普通涂料可以使被晒建筑物外表面温度降低约13.6℃,室内温度降低5.4℃。辐射率的降温效果受反射率的制约,当反射率较低时,辐射率变化对降低室内温度的影响较大;当反射率较高时,辐射率变化对降低室内温度的影响较小。此外,还探讨了太阳辐射强度、风速等外界条件对反射隔热涂料降温效果的影响。

| Abstract: | On the establishment of heat transfer model, this paper systematically studies the influence of solar reflectivity and emissivity of reflective insulation coatings on the surface temperature and indoor temperature of buildings. Calculation shows that, under the given condition, application of reflective insulation coatings can reduce 13.6 ℃ of exterior temperature and 5.4 ℃ of indoor temperature. Temperature reducing effect is restricted by the reflectivity. When the reflectivity is lower, the change of emissivity may influence the decrease of indoor temperature in bigger degree and when the reflectivity is higher, change of emissivity may influence the decrease of indoor temperature in smaller degree. In addition, this paper also discusses the influence of solar reflectivity and wind speed on the cooling effect of reflective insulation coatings. |
