It can be seen from Table 11 .1 that with the same filters and air change rate, the lesser the number of air supply outlet is, the higher the average indoor particle concentration is, when it is compared with the calculated value by the uniform distribution method. In order to make the airflow and particle concentration fields uniform, there must be sufficient air flow rate to dilute, and the dilution area should be as large as possible, until the whole room. For a small number of air change rate, the measured particle concentration is higher than the calculated value. For a large number of air change rate, the measured particle concentration is lower than calculated value.	./cache/cord-032157-q1sbvjvx.txt	./txt/cord-032157-q1sbvjvx.txt
