Improving smoke control in enclosed car parks
Flakt Woods has published a guide on how to calculate the effect of jet fans on air and smoke flow rates in enclosed car parks. ‘A practical guide to smoke control for enclosed car parks aims to help designers draw up a jet-fan solution so that in the event of a fire smoke can be effectively removed rather than accumulating in or spreading to other parts of a car park.
The guide’s author, James Allen, senior fire safety and CFD design engineer, explained: ‘Many enclosed car parks throughout the world employ jet fans to help clear smoke in the event of a fire with good effect. However, current practice relies heavily on air-change rates when designing such systems. Although this approach goes some way in assisting designers to meet the minimum ventilation requirements in car parks, it doesn’t provide all the answers to ensure that a proposed jet fan system will not cause smoke to spread.’
