众所周知，厨房排烟系统很复杂，既然是系统，就是无缺的规划，风机的大小，烟罩的程度，油烟的处理技术，以及配套的救活和燃气保护等等一系列，包含结尾的油烟净化器和风机，都有很严格的规则和要求。
As we all know, the kitchen smoke exhaust system is very complex. Since it is a system, there are strict rules and requirements for the planning, the size of the fan, the advanced level of the hood, the treatment technology of the lampblack, and the supporting life-saving and gas protection, including the lampblack purifier and fan at the end.
我们梳理了厨房排烟风管系统规划的几个要害：
We sorted out several key points of kitchen smoke exhaust duct system planning:
一、厨房补风要挑选有序送风
1、 The kitchen air supply should be selected in order
厨房补风有两种，一种是无序送风，会构成厨房的作业环境恶劣。是在夏季，虽然餐厅内通常会设备一些部分柜式空调机以下降餐厅的室内温度，但室内空气补入厨房，并不能厨房的热负荷并下降厨房温度。
There are two kinds of kitchen air supplement, one is disordered air supply, which will constitute a bad working environment for the kitchen. It is in summer. Although some cabinet air conditioners are usually installed in the restaurant to reduce the indoor temperature of the restaurant, the supplement of indoor air into the kitchen cannot eliminate the heat load of the kitchen and reduce the temperature of the kitchen.
一种是有序送风，在厨房的通风系统中，多为以下三种补风方法：餐厅空调为全新风直流式空调系统，空调新风首要送入餐厅，然后流入厨房经排风系统排出室外；将组合式空调机组的新风一部分直接补入厨房，一部分送入餐厅，并通过回风机回到空调机；用两台机组分别为餐厅、厨房服务，其间厨房为全新风直流系统，直接补偿厨房炉灶的排风。
One is orderly air supply. In the ventilation system of the kitchen, there are mainly the following three air supplement methods: the restaurant air conditioner is a fresh air direct-current air conditioning system, and the fresh air of the air conditioner is first sent to the restaurant, and then flows into the kitchen and is discharged outside through the exhaust system; A part of the fresh air of the combined air conditioning unit is directly fed into the kitchen, and a part is fed into the dining room, and returned to the air conditioner through the return fan; Two units are used to serve the dining room and kitchen respectively, and the kitchen is equipped with fresh air DC system to directly compensate for the exhaust of the kitchen stove.
二、合理设备排烟管道
2、 Reasonable equipment smoke exhaust pipe
厨房排烟风管的水平段不宜太长，一般水平远距离不该超过15m并且要有2%以上的斜度，水平结尾设活接头，以便利收拾油垢。排风速度按规范不得低于 10m/s，以防风速过低使油附着于烟道上，接排风罩的支管应设风量调节阀。
The horizontal section of the kitchen smoke exhaust duct should not be too long. Generally, the horizontal distance should not exceed 15m and should have a slope of more than 2%. Movable joints should be set at the end of the horizontal to facilitate the cleaning of oil dirt. The exhaust speed shall not be less than 10m/s according to the specification to prevent oil from adhering to the flue due to low wind speed. The branch pipe connected to the exhaust hood shall be equipped with an air volume regulating valve.
三、合理运用排烟设备。
3、 Use smoke exhaust equipment reasonably.
厨房排烟设备要求其外型美丽大方，排烟作用好，能与不同风格的厨房家具装饰匹配等特点，运用方法如下：
The kitchen smoke exhaust equipment is required to have beautiful and generous appearance, good smoke exhaust effect, and can match the decoration of kitchen furniture with different styles. The application method is as follows:
运用时，一般应在翻开燃气灶前1—2分钟发起饭馆厨房排烟设备。发起时好使用高速档发起，发起后可根据厨房烟气大小变化高速或低速；
When using, the smoke exhaust equipment in the restaurant kitchen should be started 1-2 minutes before turning on the gas cooker. When starting, use the high gear to start. After starting, you can change the high speed or low speed according to the size of kitchen smoke;
燃气灶应在厨房排烟设备正下方，抽烟作用好；
The gas cooker should be directly below the kitchen smoke exhaust equipment, which has a good smoking effect;
厨房排烟设备应在做完饭燃气灶封闭后持续作业3分钟或更长，保证把房间空气换新一次；
The kitchen smoke exhaust equipment shall continue to operate for 3 minutes or more after the gas stove is closed to ensure that the room air is renewed once;
运用时,距厨房排烟设备更近的窗户应关严，把门开一条缝，防止构成比较大的空气对流,并能及时补偿厨房内空气。
When using, the window nearest to the kitchen smoke exhaust equipment should be closed tightly, and the door should be opened with a seam to prevent the formation of relatively large air convection, and can timely compensate for the air in the kitchen.
