| 1. | Through having done field surveys in the campus of chongqing university , this paper tested classroom indoor and outdoor climate parameters in june , july and september of 2005 , it used questionnaire to acquire subjects ’ thermal sense , draft sense and humidity sense in classroom each month , and programmed composition to compute predicted mean vote and compared pmv with the field testing results of mean thermal sensation vote . it is discovered that pmv is overvalued the college student ’ thermal sensation in chongqing . it finds that people in chongqing adapt to the typical summer hot and winter cold sweltering weather
对重庆地区高校教室的现场调查,测试了重庆大学2005年六月、七月和九月教室室内外热环境参数,通过采用问卷主要掌握了受测对象教室里的冷热感、气流感和潮湿感,通过编制程序求得预测平均热感觉评价pmv的值,比较pmv和问卷调查得到的平均热感觉mtsv ,发现pmv预测值高估了重庆地区高校学生的热感觉,这里的人群对重庆这种夏热冬冷地区比较典型的闷热气候具有一定的热适应性,对现场问卷调查的结果进行分析,得出了室内空气温度、气流速度、相对湿度与人体主观感觉之间的回归曲线,发现重庆地区高校学生热中性时的空气温度为25 . 5 , fanger根据欧美人群调查得到的公式计算出的预测热感觉为中性时的空气温度为25 . 0 ,两者相差0 . 5 。 |
