Abstract:
This paper analyzes and simulates the effect of the air change rate per hour (ACH) on contamination diffusion airflow field in turbulent clean-room of hole-board ventilation by using CFD. The quality of Contaminant Removal Effectiveness (CRE) is compared with ACH ranging from 15 to 70. According to the simulation,it is the best condition of CRE in clean room when air change rate is 55 per hour,and the conclusion provides a theoretic basis for engineering design.
