• In this paper, the characteristics of moisture ventilation in the lithium ion battery manufacturing dry room are studied numerically using the standard k-ε turbulence model. A steady-state and unsteady behavior of moisture ventilation is analyzed by considering two different cases; i.e., local moisture generation and uniformly distributed moisture generation in the room. In order to evaluate the characteristics of moisture ventilation, three scales of ventilation efficiency and characteristic ventilation time are presented from numerical results. It was shown that moisture diffusion was dependent strongly on the flow field. The characteristics of moisture ventilation were improved by 20% and 40% in terms of 1st scale of ventilation efficiency(SVE1) and 2nd scale of ventilation efficiency(SVE2), respectively, through the modifications of design variables such as the addition of inlets, outlets and partition. A significant improvement in the characteristic ventilation time and moisture exhaust efficiency was also achieved by these modifications.
