2 术 语

2.0.1 烹饪热羽流 cooking thermal plume

烹饪过程中产生的油烟、热蒸汽等的气溶 胶混合物与周围环 境空气存在密度差，在浮力作用下流动和扩散形成的流场。

2.0.2 油烟 oil fume

食物烹饪、加工过程 中挥发的油脂、有机质及其加热分解或 裂解产物，统称为油烟，包括掺混于空气中的气态、液态和固态 污染物 。

2.0.3 吸油烟机 range hood

安装在炉灶上部，用于收集 、处理被污染空气的电动器具。

2.0.4 户用排油烟装置 house hold oil fume exhaust device

用于收集和排除住宅中烹饪产生油烟的器具，包括吸油 烟 机、排烟罩等。

2.0.5 排油烟防火止回阀 oil fume exhaust and fire resisting check damper

安装在公 共排油烟风道进气口处，吸油烟机工作时呈开启状 态 ，吸油烟机不工作时则处于自然关闭状态 (防止油烟回流)， 厨房或公共排油烟风道内温度达到限值时可 自动关闭，满足耐火 性能要求、起隔烟阻火作用的阀门。

2.0.6 公共排油烟风道系统 public oil fume exhaust duct system
由排油烟风道、排油烟防火止回阀、防倒灌风帽或屋顶风机 成套组合形成，用于排除厨房烹饪过程中产生油烟的整体系统。

2.0.7 捕集效率 capture efficiency

排油烟装置捕集烹饪过程产生的油 烟及其他产物的效率，指进人排油烟装置的污染物质量与烹饪过程产生的全部污染物质量 之比，以百分率计。

2.0.8 分散式动力排油烟系统 distributed-power oil fume exhaust system

以吸油烟 机为动力进行排风的住宅厨房通风系统。

2·0·9 集中式动力排油烟系统 centralized一power oil fume exhaust system
