This study aims to find out the relationship between human overall satisfaction and indoor air quality, so as to evaluate the thermal comfort of human body under the combined action of various factors. This study adopts the research method of combining objective measurement with subjective questionnaire. In terms of objective measurement, the main test parameters include indoor temperature, wind speed, relative humidity, carbon dioxide concentration, outdoor temperature and outdoor relative humidity. The test instrument adopts hand-held multifunctional anemometer and indoor thermal environment and air quality tester. Through the analysis of the measured data and the questionnaire survey, it is found that the indoor thermal environment of the classroom in November is basically comfortable, and it will be slightly cold on low temperature days. The subjective voting TSV is consistent with the predicted PMV, but the value is relatively low, which is mainly caused by the non-artificial air conditioning environment, human subjective expectation and adaptability.
