教学楼中庭的自然通风与热环境分析

Natural Ventilation and Thermal Environment in the Atrium of Teaching Building

中庭的存在对建筑通风与热环境具有重要影响。通过对武汉地区某教学楼中庭内的温度场与室外微气候进行了现场实测,对所测的数据进行了分析整合,并应用CFD数值模拟方法对中庭垂直温度梯度等参数进行了模拟,研究表明:实测数据与模拟结果在允许的误差范围内能够很好地吻合,且中庭内的垂直温度梯度对自然通风影响很大,中庭外窗的充分开启有利于夏季自然通风和节能。

The existence of atrium is crucial to buildings＇ ventilation and thermal environment. The temperature distribution in atrium and outdoor micro-climate is tested, analyzing the measured data and simulating the temperature distribution in atrium with numerical method, which indicates that the simulated results can be well agreed with the measured results, and the temperature stratification will significantly impact on natural ventilation. And it＇s useful for natural ventilation and encrgy-saving during the atrium windows open fuUy.
