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
