本文对西安地区学生公寓过渡季(春季)的室内空气温度、相对湿度、风速等参数进行了测试和统计,对公寓内的学生进行了问卷调查,并用ASHRAE的7级热感觉标度对相应的热感觉主观反映进行了调查统计。而后,运用统计学分析方法对平均热感觉、衣服热阻与操作温度进行了回归分析,得到了过渡季的实测热中性温度为18.8℃、理论热中性温度为19.2℃,并对其进行了修正,得到期望因子e=0.5;运用直接询问法计算得到西安地区过渡季学生的期望温度为17.5℃,学生可接受的实测操作温度的最低限值为14.5℃。本文研究可为今后寒冷地区过渡季热舒适性研究和如何延长过渡季的时间以节约能耗提供参考和依据。
This paper tests and statistics the indoor air temperature, relative humidity, wind speed and other parameters during the transitional season (spring) in the student apartment in Xi’an. The students in the apartment were surveyed and compared with the ASHRAE 7-level thermal sensation scale Feel the subjective reflection of the survey conducted a survey. Then, the average thermal sensation, clothing thermal resistance and operating temperature were analyzed by using statistical analysis method. The measured thermal neutral temperature was 18.8 ℃ and the theoretical thermal neutral temperature was 19.2 ℃ during the transitional season, The result shows that the expectation temperature is 17.5 ℃ for students in transitional season in Xi’an and the minimum acceptable temperature for students is 14.5 ℃. This study can provide reference and basis for future research on thermal comfort during the transitional cold region and how to extend the transitional season to save energy.
