基于空调使用行为的南宁地区夏季室内热舒适性研究

摘要

采用PMV-PPD指标体系,理论求解了南宁地区夏季室内热舒适范围并将其与现行标准的推荐值进行对比分析；通过对南宁市居民空调使用状况进行问卷调查并结合对当地居民潮湿感的实测分析,揭示了当地居民的热舒适需求.研究表明,居民感觉舒适时的空调设定温度为24～28℃,但80％以上的居民在温度达29 ～ 30℃时仍不需启动空调,可接受的相对湿度范围较宽.该地区夏季室内热舒适温度范围为24 ～ 28℃,可接受的热舒适上限温度为29℃,且不必过多关注相对湿度对热舒适性的影响.%The range of thermal comfort in Nanning region is calculated theoretically according to the PMV-PPD index system. Besides the theoretical evaluation is compared to the recommended values of the existing standards,the survey on the air conditioners use status of local residents is conducted in Nanning to reveal the thermal comfort requirement of local residents, combining with the test results of the residents' humidity sensation. The results show that residents feel comfortable when temperature is set between 24℃ and 28℃ ,and 80% of them do not start up air conditioners until the ambient temperature is up to 29 ～ 30℃. The residents can adapt to a wider range of relative humidity. The temperature range of thermal comfort is 24 ～28℃ and the acceptable upper temperature limit can be up to 29℃. The relative humidity is less contributing in Nanning region.
