摘要
文中选取大连市四处广场进行老年人室外活动空间热环境实测与分析.通过物理量实地测量与热舒适主观问卷发放,获得室外活动空间热环境变化趋势与老年人热感觉投票.以生理等效温度(PET)为主要指标,分析大连市老年人群在广场室外活动空间的热感知和舒适温度区间.研究结果表明,温度为影响老年人热舒适的主要因素,但老年人热敏感性较低,难以感知热暴露危险.中性PET温度为22.6℃、中性温度范围及80%可接受温度区间分别为18.76～26.45℃和10.53～27.08℃.可接受温度范围高于中性温度范围,表明老年人对热环境接受度高.研究结果对老年人室外活动空间舒适热环境营造能够提供数据支撑,为老年人适老化建设及相关研究提供理论基础.
Abstract
The study selects four squares in Dalian to conduct on-site measurements and analyses of the thermal en-vironment for outdoor activities for the elderly.By measuring physical quantities and distributing subjective ques-tionnaires on thermal comfort,the research obtains trends in the thermal environment of outdoor activity spaces and the thermal sensation votes from elderly participants.Using Physiological Equivalent Temperature(PET)as the main indicator,the study analyzes the thermal perception and comfort temperature ranges of the elderly population in the outdoor activity spaces of the squares in Dalian.The results indicate that temperature is the primary factor affecting the thermal comfort of the elderly;however,their sensitivity to heat is relatively low,making it difficult for them to perceive the dangers of heat exposure.The neutral PET temperature is found to be 22.6℃,with the neutral tempera-ture range and the 80%acceptable temperature range being 18.76-26.45℃and 10.53-27.08℃,respectively.The acceptable temperature range is higher than the neutral temperature range,indicating that the elderly have a high tol-erance for thermal environments.The findings provide data support for creating comfortable thermal environments in outdoor activity spaces for the elderly and offer a theoretical basis for the development of age-friendly infrastructure and related research.
