Experimental study on influence of wind speed on human body thermal comfort in office buildings in summer

Carries out an experimental study combining the subjective questionnaire survey with the physiological index test, and analyses the variation characteristics of physiological indexes and subjective evaluation indexes under different wind speed conditions. Establishes the model of wind speed and physiological indexes and the model of physiological indexes and subjective evaluation indexes respectively and predicts these indexes. The research results show that under different wind speed conditions only skin temperature closely associates with skin heat conduction flux and decreases with the increase of wind speed, and the changes of heart rate and the variability are not obvious. Under the established thermal environment conditions, the acceptable wind speed range of the respondents is 0.15 to 0.35 m/s, and the neutral wind speed is 0.3 m/s.
