摘　　要：选取接触式、核心式、嵌入式、线性式四种中庭形式,利用正交试验设计方法得到室外风向、风速、温度、太阳辐射强度、室内热源强度和有效开口面积比六个影响因素下的中庭办公建筑自然通风数学模型,结合标准气象年数据得到了办公建筑在不同气候条件下的中庭类型选择和开口大小设计策略。通过研究发现：在哈尔滨、北京和上海地区,四种中庭形式在同一地区的自然通风潜力基本相同;在广州地区中庭建筑宜采用核心式中庭;而在昆明地区中庭建筑宜采用接触式中庭;对于哈尔滨、北京、上海、广州,建筑自然通风开口面积比应逐渐升高,其大小分别为15%、17.5%、20%、25%,而昆明地区所需开口面积比较小,建议值为12.5%。This paper select the four form atrium,by orthogonal experimental design method,obtain the mathematical model of natural ventilation based on the outdoor wind direction,wind speed,temperature,solar radiation intensity,indoor heat source intensity and effective open area in the office building with atrium.Combined with the standard meteorological data,the design strategy of the atrium type selection and the opening size of the office building under different climate conditions can be obtained.It is found that the natural ventilation potential of the four types of atrium in Harbin,Beijing and Shanghai is similar,and in Guangzhou,it is advisable to adopt the core type atrium,while in Kunming area,it is appropriate to adopt the contact atrium.For Harbin,Beijing,Shanghai,Guangzhou,the building natural ventilation opening area ratio should be gradually increased,the value is 15%,17.5%,20%,25%,while the Kunming area is small,the recommended value is 12.5%.
