专注通风管道加工·排烟罩

1、 The diameter of the exhaust pipe is inconsistent with that of the range hood itself

如预留管径过小，而油烟机管径过大，两者相接，容易出现回风问题，排风量会锐减。所以在安装时要注意管径是否相同。

If the reserved pipe diameter is too small, and the pipe diameter of the range hood is too large, the two are connected, which is prone to return air problems, and the exhaust air volume will be sharply reduced. Therefore, pay attention to whether the pipe diameter is the same during installation.

二、排风管不宜过长且弯折过多

2、 The exhaust pipe should not be too long and bent too much

管径距离应在4m~6m之间，在吸油烟机更上方，可隐藏在吊柜中，要避免有俩次以上的弯折，每次弯折会降低30%的吸力。

The best distance of pipe diameter should be between 4m and 6m, and the best distance is at the top of the range hood, which can be hidden in the wall cabinet. Avoid more than two bends, each bend will reduce the suction by 30%.

三、吸油烟机尺寸小于燃气炉尺寸

3、 The size of the range hood is smaller than that of the gas stove

燃气炉的宽度一般约为70-80厘米，抽油烟机的宽度为60-90厘米，在配置上以“抽油烟机大于燃气炉”为原则，例如70厘米的燃气炉配80厘米的抽油烟机。

The width of the gas stove is generally about 70-80 cm, and the width of the range hood is 60-90 cm. The configuration is based on the principle of "the range hood is larger than the gas stove". For example, a 70 cm gas stove is equipped with an 80 cm range hood.

四、装设位置附近门窗过多

4、 Too many doors and windows near the installation position

摆放位置附近更好不要有太多门窗，以免发生空气对流而无法发挥正常的排烟效果。

It is better not to have too many doors and windows near the placement location, so as to avoid air convection and unable to play a normal smoke exhaust effect.

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 in the kitchen. In summer, although some cabinet air conditioners are usually installed in the dining room to reduce the indoor temperature of the dining room, supplementing indoor air into the kitchen does not eliminate the heat load of the kitchen and reduce the kitchen temperature.

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 kitchen ventilation system, the following three air supplement methods are commonly used: the dining room air conditioner is a fresh air DC air conditioning system, and the fresh air of the air conditioner is first sent to the dining room, and then flows into the kitchen and is discharged outside through the exhaust system; One part of the fresh air of the combined air conditioning unit is directly fed into the kitchen, and the other 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 a fresh air DC system, which directly compensates the exhaust air of the kitchen stove.
