• contaminant concentration

The effect of heating by charcoal basin in a rural residence in Hunan Province on the indoor air quality was studied in winter using the multi-zone airflow model. Firstly, the emission rates of carbon dioxide (CO2), sulphur dioxide (SO2) and particle material (PM) which emitted from charcoal basin were calculated by experimental methods; Secondly, the multi-zone airflow model was adopted to simulate the airflow of natural ventilation and contaminant transport in different zones of the building in the situation of opening or closing the interior doors and locating the charcoal basin in different rooms. It is concluded that: 1) heating by charcoal basin causes the concentration of individual contaminant far beyond the standard level in some rooms; 2) the open condition of interior door affects the airflow and contaminant transport through the rooms; 3) concentration of contaminant in the room where pollution source exists is higher than that in other rooms; 4) indoor air quality of case 3 is the best in all the cases.
