IMPROVED PERFORMANCE OF COOKER HOODS

The Centre for Industrial Diagnostics and Fluid Dynamics (CDIF UPC) has carried out a project with Pando to improve the acoustic performance and fluid dynamics of extractor hoods manufactured by the company. CDIF UPC carried out an acoustic and fluid dynamics study of all Pando hoods on the market, to find out their qualities and limitations using experimental measurements and numerical simulation. The data were then used to optimize the model by increasing the fume extraction area, improving the air path from the exterior to the inlet of the fan in order to increase the suction, and increasing the isolation of the system. These improvements led to a 40% reduction in pressure drop and a 2 db reduction in noise level.
