At a given air inlet condition and airflow rate, meanwhile, dryness of air outlet was required, proper heat-transfer area and matching refrigeration system are obtained through calculating.

And compared with its counterpart, the characteristics on the condition of the airflow mixed with ultrasonic induced water mist, the restriction effect by water mist on plywood was discovered.

Usually, numerical simulation and experiment method are be used for analyzing the interior airflow field under the condition of natural ventilation.
