摘要
全球变暖使高温热浪愈发频繁,导致居民室外生产生活热安全风险提高。乔木遮阴是改善室外空间热环境的关键因素,为量化室外环境的热安全风险,保障室外活动时人群的热安全,本文建立了一种基于ENVI-met热环境模拟软件耦合人体二节点热反应模型的人体室外热安全活动时间计算方法,并以乔木遮阴间隔不同的4种室外空间工况,进行了案例分析。该方法可用于评价室外空间在各季节的安全使用时间,亦可用于辅助新建室外空间方案的热环境设计以消除热安全风险。
Global warming makes high temperature heat wave more and more frequent,which leads to the low quality of living and increase of thermal safety risk of outdoor activities.Tree shadow is the key factor to improve the outdoor thermal environment quality.In order to quantify the thermal safety risk of outdoor environment and ensure the thermal safety of people who go out in high temperature time,this paper sets four outdoor conditions with tree shadow of different interval in hot season.Based on ENVI-met software coupled with two node thermal response model of human body,a calculation method of thermal safety use time is proposed.This method can be used to evaluate the safe use time of the outdoor space in each season,and can also be used to guide the thermal environment design of new outdoor space to eliminate the thermal safety risk.
