| Title | A Study on the Design of Fire Suppression Systems for Electric Vehicle Fires in Underground Parking Facilities |
||
| Keyword | |||
| Abstract | The underground parking facilities studied in this research are relatively enclosed. In the event of an electric vehicle (EV) fire, conventional top-down fire suppression systems often fail to effectively control the fire in its early stages. Additionally, due to the operational risks associated with fire blankets, this study proposes a bottom-up suppression approach, introducing three integrated designs that combine automated fire blankets with water mist systems, as well as three water barrier systems that submerge the EVˇ¦s undercarriage. Through comprehensive analysis using SWOT methodology, the study found that the three integrated designs of automated fire blankets and water mist systems require specific spatial conditions and involve high costs due to the expensive nature of water mist systems. However, automated fire blankets eliminate the risk of personnel exposure during manual deployment, and the water mist systemsˇ¦ low water consumption results in minimal water damage and lower water supply requirements. While the fire blanket can block dense smoke and extend evacuation time, it cannot prevent the continued thermal runaway of EV batteries, posing residual risks to firefighting operations. Among the three water barrier designs that submerge the EV undercarriage, the inflatable water barrier system features quick and simple deployment and imposes minimal space constraints. The roller-shutter-type barrier is the most cost-effective but requires a longer construction period and more installation space. The hydraulic-lift barrier system is limited by patented waterproof gate technology, leading to high costs and strict spatial requirements. All three barrier systems require a substantial water supply to effectively isolate thermal runaway and absorb heat, but they significantly reduce the risks faced by firefighters during subsequent emergency response. |
