庭院通风对湘北农宅室内微气候的影响

The Influence of Courtyard Ventilation on Indoor Microclimate of Farmhouse in the North of Hunan Province

通过分析湘北某一农村住宅(以下简称农宅)的庭院通风设计,从庭院的平面布局、空间体量、周边微环境设计、自身构造措施等角度阐述了庭院调节室内微气候(冬夏两种模式)的方式,从中总结出改善室内微气候的庭院设计方法,并将这种方法定性化,转换成建筑师易于理解和操控的方式,以便他们将这种设计方法应用于湘北农村住宅设计中,让庭院作为一种适宜的自然通风策略得到广泛的认可与运用。最后利用CFD数值模拟分析该庭院建筑的通风效果,并且对模拟结果做出分析推理。

Through the analysis of the courtyard ventilation design of a rural residential （referred to as farmhouse below） in the north of Hunan province, expound the ways that how the courtyard to adjust indoor microclimate （winter and summer two modes） by the plane layout, space dimension, the surrounding microenvironment design, its construction measures of the courtyard, then has come to the conclusion that the courtyard design method of improvement the indoor microclimate, let the method be qualitative and converted it into the way that architects can easy to understand and manipulate, so that they will use this kind of design method in the rural residential design in the north of Hunan province, make the courtyard widely accepted and used as a suitable kind of natural ventilation strategy. Finally using CFD numerical simulation to analyze the ventilation effect of the courtyard building and make analysis of reasoning to the result of the simulation.
