CHALLENGE - The design of a cooker hood concerns different aspects, such as the aesthetic design, thermal and structural analysis of components, fluid dynamics performance and energy consumption.The scope of the proposed research is to evaluate the performance of a kitchen hood during the conceptual design in terms of energy efficiency to classify the product using the European energy label. An optimization analysis is proposed to enhance the design of products with reduced energy consumption.
SOLUTION - Cooker Hood Designer is the design software developed by this research activity. It includes a system solver which implements rules analyze the behavior of a cooker hood system in terms of performance, energy efficiency, and consumption. The proposed software tools have been developed using the programming environments provided by Visual Studio.NET and MATLAB and include an interface that can interact with optimization modeFRONTIER software. Concerning the optimization, the parameters to be investigated were reduced to the blower and grease filter units, where each blower consists of a motor and impeller. The MOGA-II algorithm was used for the proposed discrete multi-optimization analysis. The objective functions were minimization of the energy consumption (low AEC values) and maximization of the air flow rate.
BENEFITS - An integration with MOGA-II genetic algorithm provides the possibility of optimizing a product configuration investigating different variations of components. The resulting cooker hood provides air flow of 1050 m3/h with an FDE of 29.20 FDE and an A-class EEI index.
