摘要
以德州市和睦家养老院为对象,对夏季养老院室外环境的老年人热舒适性展开研究。通过调查问卷的方式确定了本地老年人夏季进行室外活动的主要时间段分布,并根据德州市2019年7月份气象数据设定了不同时间段下的5种典型工况,基于CFD软件对各典型工况下的养老院室外环境风速分布进行了数值模拟;根据室外环境风速分布,结合适用于老年人生理特征的经验公式,计算得出养老院特色庭院区域以及广场区域在不同时间段下的气流感(DSV)和热感觉(TSV)评价结果;此外还提出了热舒适性系数(TCI)概念,用于量化评价室外环境老年人热舒适性,并以此为依据指导下一步对于养老院室外环境热舒适性的优化。
Based on the situation of Hemujia Nursing Home located in Dezhou,the thermal comfort of elderly people in outdoor environment during summer has been investigated. The outdoor activity time distributions of local elderly people were obtained according to the questionnaire. Combined with the meteorological data of July 2019 in Dezhou,five typical conditions under different activity time were set.The wind velocity distributions of the outdoor environment under each typical condition has been simulated using CFD software. And the draft sensation vote( DSV) and the thermal sensation vote( TSV) of the different residence regions and square regions in the outdoor environment have been calculated by the experience formula which has been modified according to elderly people ’s physical characteristics. In order to evaluate the thermal comfort of the outdoor environment quantitatively,thermal comfort index( TCI) has been induced based on the results of DSV and TSV,and was used to guide the elderly people’s thermal comfort optimization of the nursing home’s outdoor environment.
