Manufacturing of hood and factors affecting hood efficiency

In this thesis study, hoods used in ventilation systems are mentioned. Starting from the hoods that are mainly used in kitchens and similar places, the components that make up the hood are mentioned. In addition, fan groups were designed with CAD software, and combinations were created by changing the components that make up the fan, and it was determined how these fan groups affected the QBEP, PBEP and WBEP parameters. At the same time, the combinations of these fan groups created also create combinations in the products, and the changes in the values such as fluid dynamics efficiency (FDEhood), energy efficiency index (EEIhood), current, power, flow rate and speed depending on the change in the geometry of the hoods, the components used in the products and the way the product is used are determined by statistical and comparative analyses. The tests were calculated using ILK FlowMeas, 3P Engineering program and methods in accordance with EU 65/2014, 66/2014 energy standards.
