Test and Evaluation of the Smoke Control Capabilities of the San Diego Veterans Administration Hospital.

摘要

A study was made by the National Bureau of Standards to evaluate the smoke control capabilities of the San Diego Veterans Administration Hospital. A unique feature of the hospital is the presence of independent air-handling units for each floor and each wing. This feature allows the air-handling units to be manipulated for smoke control following the systematic pressurization concept. Systematic pressurization is a means of smoke control whereby a building is divided into either vertical or horizontal compartmented zones such that the air-handling systems are designed to exhaust the immediate fire zone and pressurize the adjacent surrounding zones upon detection of smoke. An experimental technique of smoke simulation and smoke movement measurement was used for the study. The effectiveness of the systematic pressurization smoke control concept is demonstrated by the simulated smoke concentration profiles and pressure measurements.
