窗墙比对室内热舒适性指标PMV影响的研究

通过建立数学模型进行数值模拟计算,在相同节能改造方案下,对窗墙比与热舒适性之间的变化关系进行了研究。研究表明:窗墙比为0.2时室内舒适性指标较高,但窗墙比为0.32和0.4时的室内舒适性指标基本相同,而且窗墙比为0.32时的室内舒适性指标稍小于窗墙比为0.4时的室内舒适性指标,这与通常窗户越小越舒适的说法有所不同。

Study on the influence of the window-wall ratio on indoor heat comfortability index PMV

To study the connection between the window-wall ratio and the heat comfortability under the same reform scheme,a mathematical model was built and a numerical simulation was conducted.The result shows that when the window-wall ratio is 0.2,the heat comfortability is better than that when the window-wall ratio l is 0.32and 0.4;when it is 0.4,the heat comfortability is a little better than that when the window-wall ratio is 0.32,so namely they are almost the same.It is different from the commonly referred statement that the smaller the window is,the better the heat comfortability is.
