Pressurisation quantitative multiétagée dans les environnements contrôlés et critiques.

Quantitative multistage pressurizations in controlled and critical environments.

Résumé

The space pressurization technique is one of the key elements in design of controlled or critical environments. This technique is much more complicated for multiple rooms under various and staged pressurization levels, and the design criteria of this "multistage" or "cascade" pressurization technique has traditionally been applied based on offhanded or intuitive guesswork. A recent ASHRAE research paper established a quantitative relationship between a room's pressurization ratio and its air leakage flows. As a further development, the focus of this paper is to explore this quantitative approach in the field of multistage pressurizations. A simplified case study demonstrates the detailed procedures for arranging supply, return, and exhaust airstreams for rooms under various required pressurization levels.
