Experimental study on the effect of the split-type air-conditioner on the transmission of smoking pollutants in a room.

Environmental tobacco smoke (ETS) has become one of the most important sources of indoor air pollution. The study aimed to obtain the variation characteristics of typical air pollutant concentrations when people smoke in a closed room and explore the effect of the air-conditioner. A closed and air-conditioned room of 21 m was taken as the research object.

Indoor air quality investigation of a badminton hall in humid season through objective and subjective approaches.

This study investigated the indoor air quality (IAQ) during humid season in an old badminton hall, to explore the IAQ characteristics of natural ventilated sports buildings for public use. The indoor air parameters (temperature, relative humidity and air velocity) and indoor air pollutants (CO, TVOC, PM and PM) were measured. A subjective approach was carried out through questionnaire survey.
