Impulse v Induction
Architects, Consulting Engineers and Regulators alike can be forgiven for being confused by the options now being promoted for use in Impulse Ventilation Systems for the ventilation of basement and enclosed car parks.
Since the launch of impulse ventilation into the United kingdom in 2000 by PSB UK Ltd, this type of system has caught the imagination of the industry and now impulse ventilation is used in over 90% of car park that require mechanical ventilation.
During the last three years, PSB UK Ltd has developed many new products and system design techniques to improve safety, aid building design and reduce energy consumption. The new products include the Axial type of impulse fan and the Centrifugal type of induction fans. A number of companies are now marketing this type of product, but without a full understanding of their application, there are many pitfalls, with potentially significant consequences, awaiting the individual responsible for the design of the ventilation system.
The industry is asking when should the Impulse fan be used and when should the induction fan be used and what are the relative benefits and disadvantages of each.
These two ranges of fans are basically designed to provide the same functions and these are:
- Influence the direction of airflow within the car park to ensure that all areas are efficiently ventilated
- Induce air turbulence during daily ventilation to ensure efficient mixing and dilution of pollutant gases with fresh air
- Manage the flow of hot smoky gases in the event of fire
In addition to these three performance requirements common to both, it is now a mandatory requirement that these fans comply fully with the requirements of BSEN12101-3 and certificates provided to testify that the product has been successfully tested to withstand 300oC for a period of not less than 60 minutes.
