At present, our country regulated that the air exchange rate in infectious ward should be 10 to 40 times per hour. The United States, Australia, Britain regulated that the air exchange rate in infectious ward should be not less than 12 times per hour, under the conditions of restriction, the air exchange rate should be not less than 6 times per hour. However, for different forms of ventilation and room types, people need to specific study in order to achieve the reasonable air exchange rate. By the method of numerical simulation, with particle size of 5 μm and 20 μm as example, in the condition of the wall attached jet, the paper researched the effects of different air exchange rate for discharging indoor pollutant efficiency.
