摘要

以带有吸油烟机的家庭闭式厨房为研究对象

数值研究了烹饪过程中厨房内部热环境以及烹饪者对温度和油烟污染的感知。根据已获得的关于气幕式吸油烟机的最佳设计参数组合方案

从人体感知温度、人体感知油烟浓度、油烟释放温度、油烟逃逸浓度4个方面对比了原型吸油烟机和气幕式吸油烟机对厨房环境的影响

并数值分析了带有吸油烟机的厨房内油烟流动特性及其逃逸机理。研究结果表明:引入合理设计的气幕式吸油烟机能有效抑制厨房内油烟和热空气逃逸

降低人体面部区域对油烟和高温的感知

使厨房内操作者的舒适度得到提高。

Abstract

A residential kitchen was selected as the studied object

and the indoor air environment including the distribution of temperature and oil fumes pollutant in the closed kitchen with the range hood system was simulated numerically by using the commercial CFD software CFX. On the basis of the optimal scheme on the air curtain range hood obtained in the previous paper Part I

the effects of the original and improved range hood on the kitchen environment were analyzed respectively according to the body perception to temperature and oil fume concentration

oil fume temperature and oil fume escaping. The flow characteristics and spillage mechanisms of the oil fumes were also presented in the kitchen. The results show that the improved range hood can restrain the oil fume to escape into the kitchen. The perception to the oil fume with high temperature in the body facial region can be reduced by using the improved range hood

and the comfort of cooking in the kitchen is improved.
