Car Park & Garage Ventilation Jet Fans
Whether for simple pollution control, smoke clearance or complete smoke control, almost every car park need ventilation. Understanding why is key to designing and specifying the right system for each car park.
Whether for simple pollution control, smoke clearance or complete smoke control, almost every car park need ventilation. Understanding why is key to designing and specifying the right system for each car park.
Traditional parking ventilation system designs are based on duct runs with high and low level extract or more simplistic designs with extract fans and supply from fresh air ramps. The goal is to remove the need for any ducting by using Jet Fans to distribute the air. Woods Air Movement can support your design and solution by demonstrating the benefits to client and user alike covering local and national American Standards.
Unlike traditional system design approaches, with the Woods Air Movement solutions, single or multiple points of extract are placed strategically, with Jet Fans that may operate independently or in groups.
During day-to-day operation, the level of Carbon Monoxide is constantly measured by gas monitoring sensors throughout the car park level.
Upon detection of increased levels of contaminants, selected Jet Fans are activated to dilute the contaminated air and guide it towards the point of extract.
In the event of a fire, a smoke detection system will cease the day-to-day operation of the car park ventilation system. Depending on the chosen system design approach, the system will be reactive to either clear the smoke or to provide increased visibility to allow improved conditions which leads to more efficient firefighting deployment.
Our car park ventilation solutions are designed for the specific structure. Computational Fluid Dynamics (CFD) software, combined with Woods Air Movement in-house expertise and own fully-researched input data is used to validate the overall performance of the system both in day-to-day and emergency smoke extract mode.
CFD Analysis allows Woods Air Movement engineers to assess the car park operation with respect to its acceptance criteria; this could be air quality or average air charge rate or minimum airflow speed to maximum allowed smoke spread depending on the project need. The engineer can then optimise the position and operation of the system to best suit the criteria. This is supported pre-CFD by detailed calculations to demonstrate system compliance and ensure that the system can achieve the required criteria.
