对广州地区某校园夏季室外热环境进行了现场测试。在2014年8月至2014年10月期间,对环境参数开展现场测试和问卷调查研究,问卷调查共收到有效问卷1 582份。研究结果表明,广州地区夏季室外中性温度为23.9℃,而期望温度为23.7℃。广州居民对温度变化的敏感与其他地区存在不同程度的区别。可接受热舒适分析表明,90%被测对象可接受的热环境对应的SET*上限为28.54℃,与其他地区可接受温度上限值有明显不同。运用线性回归的方法,建立了当地的热环境评价指标ASV*,为环境设计者提供参考。
A campus in Guangzhou in summer outdoor thermal environment conducted a field test. From August 2014 to October 2014, a field test and questionnaire survey on environmental parameters were conducted. A total of 1 582 valid questionnaires were received in the questionnaire. The results show that in summer in Guangzhou, the outdoor neutral temperature is 23.9 ℃, while the expected temperature is 23.7 ℃. The sensitivity of Guangzhou residents to temperature change is different from that of other regions. Acceptable thermal comfort analysis shows that the SET * upper limit corresponding to 90% of the tested subjects’ acceptable thermal environment is 28.54 ° C, which is significantly different from the acceptable upper temperature limit of other regions. Using the method of linear regression, the local thermal environment assessment index ASV * was established, which provides reference for environmental designers.
