城市户外环境热舒适度评价模型

Modeling of evaluation metropolitan outdoor thermal comfortable degree

随着城市大规模发展 ,人们生活水平不断提高 ,在人口稠密的城市户外休闲环境中 ,热舒适性显得越来越重要 .本文根据室内热舒适指标 PMV,建立了评价户外热舒适的数学模型 ;该模型在室内能与 PMV很好的吻合 ;与湿黑球温度 WBGT热应力指标相比 ,更能反映人体热感觉 。

With the rapid expansion of metropolitan and the striking improvement of people' living standard,the outdoor environment is more and more important to the densely populated areas inside the city.In this thesis,based on PMV -index which is used to evaluate indoor thermal comfortable degree,a mathematic model is proposed to evaluate outdoor thermal comfortable sense of human body.Compared with Wet Bubble Globe Temperature index ( WBGT ),the model responds to the thermal sense of human body in an effeclive.The model is a useful tool for the design and evaluation of building environments.
