Study of indoor air quality and thermal comfort of public place
Indoor air quality (IAQ) is being paid more and more attention to by researchers and engineers. The IAQ and thermal comfort (TC) of public places have been the hot problems recently. To study the poor air quality and insufficient ventilation in Internet bars in Lanzhou, one Internet bar was selected as the aim to measure its thermal environment parameters and the questionnaire investigation was conducted to obtain the information of its IAQ and thermal comfort. The results showed that: (1) The CO2 concentration, which is often considered as the evaluation index of IAQ, was much higher than that of the relative standard; (2) The PMV (Predicted mean vote)-PPD (Predicted percentage of dissatisfied) index was not consistent with those of the questionnaire since human ability to adapt to the severe environment was underestimated in the former evaluation process.
