Abstract
Fume exhaust devices play an important role in creating healthy kitchen environment. Integrated stove is an emerging side suction fume exhaust device with an exhaust outlet closer to the emission source. In capturing fumes, the integrated stove is a great improvement over the previous top suction fume exhaust device. For further optimizing the control effect of integrated stove on fumes and reducing the pollution of kitchen environment by cooking, this study proposed a new kitchen ventilation approach with integrated stove air supply and fume exhaust (ISASFE). Its performance of capturing fine particulate matter (PM2.5), a typical pollutant in fumes, and its energy-saving effects were investigated. Employing a blend of orthogonal design and CFD simulations, five key factors affecting its operational effectiveness were analyzed deeply. The fume exhaust effectiveness of ISASFE was assessed utilizing capture efficiency. The energy-saving effect of ISASFE under different emission rates was analyzed by using polynomial fitting and actual measurement methods. Results demonstrate downward air supply speed and exhaust rate as the most crucial factors, with upward air supply speed, downward air angle, and emission rate following in importance. Compared to the conventional stove without air supply, ISASFE exhibited enhanced capture efficiency by 1.8% at low, 13.9% at medium, and 14.5% at high emission rates, respectively. The energy saving rate of ISASFE was 23%-42%. The new ventilation strategy proposed in this study not only enhanced the PM2.5 capture efficiency of the side suction integrated stove, but also helped to reduce the kitchen ventilation energy consumption.
