摘要：采用正交分析的方法对中庭热环境的主要影响因素——中庭断面面积、室外温度、顶部天窗开启百分比进行试验设计,针对设计工况进行数值模拟,并对数值模拟结果进行正交分析。研究结果表明,中庭顶部天窗开启百分比对中庭的通风量影响最大,中庭的断面面积对中庭通风量影响次之,室外温度对中庭的通风量影响相对较小,但室外温度是中庭内温度分布的重要影响因素。研究结果为中庭科学设计和合理运行管理提供了依据,同时对已建成的建筑中庭提出了改善热舒适度和节能的措施。
Atrium thermal amenity is determined by many factors, as were investigated widely both at home and abroad. But the relationship and interactions between these factors have not been well studied. In this paper, three thermal environment influencing factors： the cross section area of atrium, the outdoor air temperature and the top skylight opening percentage are orthogonally analyzed. First, the experimentation is designed by using the method of orthogonal analysis. Then numerical simulations are carried out according to different test conditions, and simulation results are orthogonally analyzed. The results indicate that the top skylight opening percentage has the greatest impact on the airflow volume of atrium, the section area of atrium plays a secondary role, and outdoor air temperature is relatively less important. But the outdoor air temperature is an important influencing factor on the temperature distribution in atrium. This analysis provides a scientific basis for the rational engineering design and operation management. Proposals for improving the thermal amenity and energy efficiency for the completed building are also given.
