一、厨房补风要选择有序送风
1、 Orderly air supply shall be selected for kitchen air supplement
厨房补风有两种，一种是无序送风，会造成厨房的工作环境恶劣。是在夏季，虽然餐厅内通常会安装一些局部柜式空调机以降低餐厅的室内温度，但室内空气补入厨房，并不能厨房的热负荷并降低厨房温度。
There are two kinds of air supplement in the kitchen. One is the disordered air supply, which will cause a bad working environment in the kitchen. In summer, although some local cabinet air conditioners are usually installed in the dining room to reduce the indoor temperature of the dining room, 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式：餐厅空调为全新风直流式空调系统，空调新风送入餐厅，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，其中厨房为全新风直流系统，直接补充厨房炉灶的排风。
One is orderly air supply. In the ventilation system of the kitchen, there are mainly the following three air supply modes: the restaurant air conditioner is a fresh air direct-current air conditioning system. The fresh air from the air conditioner is first sent to the restaurant, and then flows into the kitchen and is discharged from the 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. The kitchen is a fresh air DC system, which directly supplements the exhaust of the kitchen stove.
二、合理安装排烟管道
2、 Reasonable installation of smoke exhaust pipe
厨房排烟管道的水平段不宜太长，一般水平远距离不应超过15m并且要有2%以上的坡度，水平末端设活接头，以方便清理油垢。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 pipe should not be too long. Generally, the horizontal distance should not exceed 15m and should have a slope of more than 2%. The horizontal end should be equipped with a flexible joint 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、合理使用排烟设备。
3、 Use smoke exhaust equipment reasonably.
厨房排烟设备要求其外型美观大方，排烟效果好，能与不同风格的厨房家具装修匹配等特点，使用方法如下：
