摘要
通过分析中庭室内热环境分布的特性,介绍了利用温度基准区域模型来计算中庭室内热环境的详细方法,并给出了在自然通风时自然通风量的计算。利用区域模型计算了上海某一中庭在不同划分高度时的主体和壁面温度分布,并与实测值相比较,以研究划分高度对计算结果准确性的影响。比较结果表明:在利用区域模型计算高大空间的温度分布时,设定区域高度宜小于1m,得到的结果较为准确;自然通风能够有效地改善室内温度分层,为建筑节能提供了一种思路。
Based on the analysis of the thermal environment of atrium, zonal model with the benchmark of temperature is introduced to calculate the distribution of indoor temperature. The model is used to predict the thermal environment of an atrium in Shanghai, and the result is compared with that of test. It indicates that when the height of every zone is refined to less than 1m, the result of zonal model is consistent with that of the test. The results with and without natural ventilation are compared and it reveals that natural ventilation can effectively reduce the temperature stratification of atrium. It may be a useful method of buildings＇ energy saving.
