Abstract
In order to study the summer thermal environment in university classroom, taking a university classroom of Zhengzhou area as an example, through measuring some indoor environmental parameters such as air temperature, relative humidity, air velocity and wall temperature, the subjective feelings of participants are investigated in the form of a questionnaire, and the relationships between thermal parameters and the thermal sensation of participants are found. Then, the conclusions are obtained as follows:the fitted equa-tion of the predicted mean vote PMV and indoor air temperature ta is obtained, and the predicted thermal neutral temperature is 24. 5 ℃, the acceptable temperature range is 22. 5~26. 4℃;the fitted equation of the mean thermal sensation vote MTS and indoor air tempera-ture ta is obtained, and the actual thermal neutral temperature is 26. 7 ℃, the acceptable range is 24. 6~28. 8 ℃, which have in-creased by comparing with the predicted thermal neutral temperature; the acceptance rate of subjects to the environment is 73. 9%, which shows most of the participants on the environment are acceptable, but 19% of the participants feel hot, so the university class-room thermal environment needs to be improved.关键词
