ASHRAE LV-11-C077 - Advanced Analysis Techniques in the Design of Longitudinal Tunnel Ventilation System Using Jet Fans
January 1, 2011 - ASHRAE

ABSTRACT Application of jet fans in emergency tunnel ventilation, as an economically attractive alternative to traditional fan plants, has become more popular in the US over the past years. Also, recent literature indicates that transportation tunnels are facing increased fire loads. For example...

ASHRAE LV-11-C076 - Impact of Tunnel Ventilation on Tunnel Fixed Fire Suppression System
January 1, 2011 - ASHRAE

ABSTRACT Recently there have been major fires in a number of European tunnels that required reevaluation of road tunnel fire loads. This showed that tunnel safety requires applying a fixed fire suppression system in addition to a tunnel ventilation system. This introduces a new challenge when...

ASHRAE LV-11-C078 - Assessing the Impact Fire Heat Release Rate has on Infrastructure Design and Constructability of Rail and Road Tunnels Ventilation Systems
January 1, 2011 - ASHRAE

ABSTRACT Tunnel ventilation facilities, for road or rail tunnels, face the challenge of the design requirements imposed on them. Among them is the Fire Heat Release Rate (FHRR). Many think that the larger the FHRR, the safer the system, but the fact is that if FHRR is too large, the airflows...
