Instructions for the use of the smoke exhaust hood in the kitchen of the hotel: generally, the fan smoke exhaust hood used in the kitchen will take a large amount of air from the kitchen. The oil smoke hood will supplement the air fan - when the oil smoke is extracted, it needs to supplement the air to the kitchen, which provides about 80% of the air volume of the oil smoke. Fresh air pre-treatment fan in the working area - provide pretreated fresh air for the kitchen working area (personnel working position). This machine provides an oil fume exhaust fan which accounts for about 20% of the air volume of the oil fume exhaust - the oil and gas to the oil fume hood in the cooking area.
厨房排烟风机排烟罩除消防排烟风机管道的防火阀之外，考虑到厨房高温工作的原因。其余风机管道的防火阀建议安装150℃防火阀（与平时普通风机管道装置的70℃略有不同）,需关闭其余所有风机（消防补风靠外窗及门隙等地方进风）当消防排烟风机动作时；当开启“排油烟风机”时，需同时（联动）开启“油烟罩补风风机”与“工作区新风预处理风机”。
In addition to the fire damper of the fire and smoke exhaust fan pipe, the kitchen smoke exhaust fan smoke exhaust hood takes into account the high temperature operation of the kitchen. 150 ℃ fire damper is recommended to be installed for the fire damper of other fan pipes (slightly different from the normal 70 ℃ of the ordinary fan pipe device), and all other fans need to be closed (air supply for fire fighting is close to the outer window, door gap and other places) when the fire smoke exhaust fan operates; When the "lampblack exhaust fan" is turned on, the "lampblack hood make-up fan" and "fresh air pretreatment fan in the working area" should be turned on simultaneously (in linkage).
厨房排烟风机排烟罩的排烟管道未端需要设置排烟阀，排烟风机排烟罩与排烟管道连接处设置排烟防火阀。要注意排烟阀与排烟防火阀是功能完全不同的设备。
Smoke exhaust damper shall be set at the end of the smoke exhaust duct of the kitchen smoke exhaust fan smoke exhaust hood, and smoke exhaust fire damper shall be set at the connection between the smoke exhaust hood of the smoke exhaust fan and the smoke exhaust duct. It should be noted that smoke damper and smoke fire damper are equipment with completely different functions.
排烟阀平时常关，火灾时开，与报警主机联动，开启条件是自动报警系统发生火警（探测器报警）消防报警主机置于自动状态，排烟阀自动开启，联动排烟风机启动。排烟防火阀是平时常开，火灾时也是开启状态，但当烟气温度达到280℃时，排烟防火阀自动关闭，联动已经开启的风机停止运行。
The smoke exhaust valve is normally closed and opened in case of fire. It is linked with the alarm host. The opening condition is that the fire alarm host of the automatic alarm system (detector alarm) is in the automatic state, the smoke exhaust valve is automatically opened, and the linkage smoke exhaust fan is started. The smoke exhaust fire damper is normally open at ordinary times and is also open in case of fire. However, when the smoke temperature reaches 280 ℃, the smoke exhaust fire damper will automatically close and the fan that has been opened will stop running.
