Energy-efficiency strategies for clean rooms without compromising environmental conditions.

Author(s) : TSCHUDI W., FAULKNER D., HEBERT A.

Summary

Traditional clean-room filtration design and operation relies upon high recirculation air change rates as a means of maintaining acceptable contamination control. Clean room professionals accept recommended air-change rates that were established somewhat arbitrarily as rules of thumb. The guidelines were based upon historically adequate clean-room conditions, but they are not optimized. Disadvantages of this practice include paying a high cost for excessive airflow, as is usually the case, but also production or other work in the clean room could be adversely affected by too much or too little airflow. This paper describes research and several case study projects that suggest that control of recirculation airflow by monitoring cleanliness, or other control strategies, is a viable means to improve energy efficiency.
