However, the designers still can not figure out the air flow rate precisely based on these methods. Through investigation it is proved that this air flow rate is magnified in many cleanrooms. It is not because low-qualified air tightness of the enclosure, but because the difficulties in testing. From the view of pressure control and energy saving, the author pointed out that the air flow rate should be controlled actively and then provided the method to control it by analyzing an experiment. 【中文關(guān)鍵詞】 潔凈室; 縫隙; 壓差風(fēng)量; 壓力控制【英文關(guān)鍵詞】 cleanroom cracks pressurized air flow rate pressure control
