Effects of Indoor Temperature on Air Quality of a University Classroom: An Intervention Study in Beijing
To evaluate the effect of temperature on indoor air quality, an intervention experiment was conducted in a classroom of a university in Beijing. The indoor temperature in the control group was 27 ± 0.7 °C, while the indoor temperature in the intervention group was reduced to 24 ± 0.3 °C by running two distributed air conditioners. During both measurements, doors and windows of the experimental classroom remained closed, and air temperature, carbon dioxide (CO2) concentration and TVOC concentration in the classroom were measured. The air quality in the classroom was evaluated by 22 occupants staying inside the classroom and 22 visitors upon entering, separately. The results showed that compared with 27 °C condition, the CO2 emission rates by occupants decreased by 3.4% when the indoor temperature was reduced to 24 °C. Both occupants and visitors indicated that at 24 °C, perceived odor intensity was significantly reduced, and the satisfaction and acceptability of air quality were improved considerably.
