Abstract
Fuel combustion will release harmful gases such as CO , CO 2 , SO 2 , and NO x during cooking, and cooking oil fumes also contain acids, aldehydes, and other harmful particulate matters. Clinical diagnosis confirmed that some tiny particulate matters in oil fumes can induce many kinds of cancer. High-rise buildings of multi-dwelling units have been widely used as residential buildings with increasing worldwide population, especially in China. Therefore, air pollution in kitchens of high-rise residential buildings is attracting more and more attention in academic circles and engineering fields, especially the exhaust effectiveness and influencing factors of cooker hoods. This study focused on key influence factors of exhaust effectiveness such as the centralized flue system of high-rise residential buildings, the operating rate, the floor, the exhaust volume, and the vent opening. Commercial software Fluent was adopted to build the calculation model of cooker hoods for high-rise buildings. The temperature distribution, concentration distribution, and main escape path of oil fumes were analyzed and compared with experimental measurements. The results showed that the side and the front edge of the cooker hood close to the cooker are the main escape paths of oil fumes; the maximum escape concentrations of oil fumes are 0.247 mg/m3 and 0.265 mg/m3, respectively, under the condition of ventilation and non-ventilation; the error is only 5.0% and 11.7% compared with the experimental results. This paper is valuable for the improvement of air quality in kitchens in high-rise residential buildings, and the design and installation of cooker hoods.
Highlights
Indoor air quality is getting more and more attention, especially the pollution of oil fumes in kitchens that have an important influence on indoor air quality [1,2]
The results show that small particulate matters had obvious diffusion characteristics, and the overall matters, and the diffusion velocity of kitchen oil fumes, and the exhaust effectiveness of cooker hoods
The results show that small particulate matters had obvious diffusion characteristics, and the overall research for cooker hoods, and the effect of structure improved on the exhaust effectiveness of cooker exhaust efficiency was about 90% [13,14]
Summary
Indoor air quality is getting more and more attention, especially the pollution of oil fumes in kitchens that have an important influence on indoor air quality [1,2]. Wang et al studied the exhaust effectiveness of high-rise buildings from research for cooker hoods, and the effect of structure improved on the exhaust effectiveness of cooker the structure of centralized flues and carried out a simulation analysis of exhaust characteristics in hoods is analyzed [15,16,17]. The above research results provide important theoretical the structure of centralized flues and carried out a simulation analysis of exhaust characteristics in and engineering references for improving the exhaust effectiveness of kitchens in high-rise building. For indoor air quality or exhaust effectiveness of cooker hoods in high-rise residential buildings based on the real environment the selection and structure design of the cooker hood, it is necessary to carry out research on the or similar conditions. The characteristics of the exterior flow field and the exhaust effectiveness of cooker hoods are simulated and analyzed
