Automatic room pressurization test technique and adaptive flow control strategy in clean rooms and controlled environments.

Author(s) : SUN W.

Summary

A quantitative relationship between a room's pressurization ratio and its leakage airflows has been established in recent ASHRAE research. With this engineered approach, design of multistage pressurizations in clean rooms and laboratories can be more predictably achieved than by traditional intuitive guesswork. As a further development, a new automatic pressurization test methodology is proposed in this paper. This new method utilizes room precision pressure sensors and flow control devices to automatically measure the room static pressure and calculate the net leakage airflow.
