Instructions for use of hotel smoke exhaust hood: generally, the fan smoke exhaust hood used in the hotel will take away a lot of air from the hotel. When the oil fume hood make-up fan exhausts oil fume, it is necessary to make up air to the hotel, which accounts for about 80% of the air volume of oil fume exhaust. Work area fresh air pretreatment fan - provides pretreated fresh air for the hotel work area (personnel working position). The machine provides a fume exhaust fan accounting for about 20% of the fume exhaust volume - to exhaust the oil and gas from the fume hood in the cooking area.

酒店排烟风机排烟罩除消防排烟风机管道的防火阀之外，考虑到酒店高温工作的原因。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 smoke exhaust fan pipeline, the smoke exhaust hood of the hotel smoke exhaust fan takes into account the reasons for the high temperature work of the hotel. It is recommended to install 150 ℃ fire damper on the fire damper of other fan pipes (slightly different from 70 ℃ of ordinary fan pipe devices in ordinary times), and all other fans need to be closed (the fire make-up air enters near the outer window and door gap) when the fire smoke exhaust fan operates automatically; When the "fume exhaust fan" is turned on, the "fume hood make-up fan" and the "fresh air pretreatment fan in the working area" shall be turned on at the same time (linkage).

酒店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。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。

Smoke exhaust damper shall be set at the end of the smoke exhaust pipe of the smoke exhaust fan and smoke exhaust hood of the hotel, and smoke exhaust fire damper shall be set at the connection between the smoke exhaust fan and smoke exhaust pipe. It should be noted that smoke exhaust damper and smoke exhaust fire damper are equipment with completely different functions. 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 is in the automatic state in case of fire alarm (detector alarm) in the automatic alarm system, the smoke exhaust valve is automatically opened and the linked smoke exhaust fan is started. The smoke exhaust fire damper is normally open and open in case of fire, but when the flue gas temperature reaches 280 ℃, the smoke exhaust fire damper will automatically close and the linkage fan that has been opened will stop running.

对于餐饮业的厨房来说，酒店厨房排烟罩的好处就是排烟是否通畅，直接关系到厨房能否正常工作，油烟净化则只是厨房排烟系统中的一个净化空气的强制性功能。排烟系统和净化器的合理匹配是保证油烟净化器净化效率的关键，同时也是油烟净化器设计人员容易忽略的问题，如果排烟系统设计不合理而造成整个厨房排烟不畅，则将无法安装油烟净化器，即使安装了油烟净化器也无法正常工作。

Whether the smoke exhaust hood can purify the air in the kitchen of the hotel is directly related to the normal function of the kitchen smoke exhaust system. The reasonable matching of smoke exhaust system and purifier is the key to ensure the purification efficiency of oil fume purifier. At the same time, it is also a problem easy to be ignored by the designers of oil fume purifier. If the design of smoke exhaust system is unreasonable and the smoke exhaust of the whole kitchen is not smooth, the oil fume purifier will not be installed, and even if the oil fume purifier is installed, it will not work normally.
