摘要
为简化舒适性方程的计算过程,提出室内空气综合温度的概念,在线性化服装热阻的基础上,绘制了室温及平均辐射温度与室内综合温度的关系图。依据室内空气综合温度与PMV的单值性对应关系,绘制了室内空气综合温度与PPD的关系图。当相对湿度为50%、风速为0.2m/s时,测得围护结构表面辐射温度及室内空气温度,即可快速确定室内舒适程度。同时对相对湿度偏离50%时带来的PMV判别偏差进行了分析,给出了修正系数,可有效帮助设计人员快速判定室内热舒适度状况,以及提高热舒适相关实验研究的工作效率。
To simplify the calculation of the thermal comfortable equation,a new concept of indoor air multiple temperature（IAMT） was presented.Plot the relation chart of the IAMT with the room temperature and the mean radiation temperature（MRT） was drawn up.Considering the feature that the IAMT is One to One correspondence with the predicted mean vote（PMV）,the relation chart of IAMT and predicted percentage and dissatisfied（PPD） was drawn up.On the condition of the relative humidity 50%,air speed 0.2m/s,when measured the mean radiation temperature（MRT） and the air temperature,the PPM can be determined immediately.The deviation of PMV caused by other relative humidity was analyzed,and the correction coefficient given.This method could help designers determine the comfortable degree of the room fast,and improve working efficiency of experiments and researches on comfortable degree.
