尽管自然通风对中庭、室内热环境和降低能源使用负荷有显著影响，但人们对各种设计参数如何影响中庭热环境缺乏了解。由于中庭自然通风设计的复杂性和模拟设计工具的不足，可能导致中庭热工预测不准确。在过去的25年里，研究者们发展并提出了各种方法，如实验、理论和数值模拟来识别心房的热性能和通风性能。然而，建模条件的多样性使得很难获得将所有影响参数与中庭热状况联系起来的正确结论。本文综述了自然通风在不同气候条件下中庭建筑中的作用、有效的设计参数及其在改善热工性能和降低能耗方面的应用。这些参数包括各种中庭配置和组件，例如中庭几何形状、开口特征、屋顶特性、材料和开窗特征。综述进一步强调了可作为辅助通气方法应用于心房的不同通气技术。所引用的参数可以分为影响热性能和通风性能的参数。出风口开度是影响中庭室内热环境和通风特性的重要参数，也是降低能耗的重要因素。
Despite significant impacts of natural ventilation on atria, indoor thermal conditions and decreasing energy usage load, there is lack of knowledge about how various design parameters influence atria thermal conditions. The complexity of natural ventilation design of atria and inadequate simulation design tools may lead to inaccurate atria thermal prediction. In the past 25 years, researchers have developed and suggested various methods such as experimental, theoretical and numerical modeling to identify thermal and ventilation performances of atria. However, the diversity of the modeling conditions makes it difficult to achieve proper conclusions which link all contributing parameters to atrium thermal conditions. This paper provides a comprehensive review of previous studies on the role of natural ventilation in atrium buildings in different climates, efficient design parameters and their application to improvement of thermal performance and decrease of energy consumption. These parameters include various atrium configurations and components such as atrium geometry, opening characteristics, roof properties, materials and fenestration characteristics. The review further highlights different ventilation techniques which can be applied in atria as assisted ventilation methods. The cited parameters can be categorized into those affecting thermal performance and ventilation performance. The outlet opening size is the most influential parameter that affects both indoor thermal condition and ventilation behaviors of atria and consequently decreases energy usage load.
