摘要
本文给出了自然通风潜力评估方法,根据此方法计算出了我国典型地区的自然通风潜力并对自然通风的影响因素进行了分析。根据计算结果得出结论:不同地区的自然通风有效小时数一般占全年总时间的20%~40%左右。影响自然通风潜力的因素是室外气象参数,但是不同地区其主要影响因素不同。寒冷地区主要是温度过低而湿热地区则主要是温度和湿度过高。随着室内得热量的上升,各地区自然通风有效时数呈下降趋势。但是各个地区下降的幅度不同:广州地区下降的最为明显而哈尔滨地区下降幅度最小。
A method of natural ventilation potential analysis of different regions in china was presented in this paper. Based on this method, the result of the effectiveness of natural ventilation in typical regions was calculated and the influence factors on the natural ventilation potential was analyses. According to calculation, the result is that the effective number of hours of natural ventilation in different parts is about 20%-40%. Factor affecting the potential of natural ventilation if outdoor meteorological parameters, but in different regions its main influencing factors different. In cold regions, low temperature is the main influencing factor and in hot and humid regions the main influencing factor is high temperature and humidity. With the indoor heat rising, the effective number of hours decline. However the decrease in various regions is different: Guangzhou is the most obvious and Harbin is the smallest.
