Ductwork channels are essential to the ventilation of buildings as they contribute to better indoor air quality irrespective of external weather conditions throughout the year.
BS EN 14239 provides a method of measurement to establish the surface area for use in further calculations for ductwork in ventilation and air conditioning systems. The main objective of BS EN 14239 is to provide best industry practices to ensure optimal performance of ductwork for building ventilation systems.
BS EN 14239 specifies the requirements for the measurement of the surface area of a duct for use in the determination of air leakage flow rate per unit surface area (leakage factor).
BS EN 14239 is applicable to circular and rectangular ducts and components used in air conditioning and ventilation systems in buildings.
BS EN 14239 on measurement of ductwork surface area for building ventilation is relevant to:
For the efficient and optimal performance of ductwork, it is vital that the measurement of surface area be calculated to determine the leakage factor, so that incidents of product failures such air leakages are minimized.
In this regard, BS EN 14239 covers measurement of circular and rectangular ductwork and provides their respective duct surface areas for use in calculations. As a result, you can demonstrate whether your design, dimensions and duct sizing can contribute to the overall efficiency of building ventilation systems.
As a result, adopting BS EN 14239-compliant duct surface areas in calculations can contribute to the reduction in air leakage rates.
