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

如預(yù)留管徑過小，而油煙機(jī)管徑過大，兩者相接，容易出現(xiàn)回風(fēng)問題，排風(fēng)量會(huì)銳減。所以在安裝時(shí)要注意管徑是否相同。

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、排風(fēng)管不宜過長(zhǎng)且彎折過多

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

管徑距離應(yīng)在4m~6m之間，在吸油煙機(jī)更上方，可隱藏在吊柜中，要避免有倆次以上的彎折，每次彎折會(huì)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、吸油煙機(jī)尺寸小于燃?xì)鉅t尺寸

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

燃?xì)鉅t的寬度一般約為70-80厘米，抽油煙機(jī)的寬度為60-90厘米，在配置上以“抽油煙機(jī)大于燃?xì)鉅t”為原則，例如70厘米的燃?xì)鉅t配80厘米的抽油煙機(jī)。

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、裝設(shè)位置附近門窗過多

4、 Too many doors and windows near the installation position

擺放位置附近更好不要有太多門窗，以免發(fā)生空氣對(duì)流而無法發(fā)揮正常的排煙效果。

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.

廚房補(bǔ)風(fēng)有兩種，一種是無序送風(fēng)，會(huì)構(gòu)成廚房的作業(yè)環(huán)境惡劣。是在夏季，雖然餐廳內(nèi)通常會(huì)設(shè)備一些部分柜式空調(diào)機(jī)以下降餐廳的室內(nèi)溫度，但室內(nèi)空氣補(bǔ)入廚房，并不能廚房的熱負(fù)荷并下降廚房溫度。

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.

一種是有序送風(fēng)，在廚房的通風(fēng)系統(tǒng)中，多為以下三種補(bǔ)風(fēng)方法：餐廳空調(diào)為全新風(fēng)直流式空調(diào)系統(tǒng)，空調(diào)新風(fēng)首要送入餐廳，然后流入廚房經(jīng)排風(fēng)系統(tǒng)排出室外；將組合式空調(diào)機(jī)組的新風(fēng)一部分直接補(bǔ)入廚房，一部分送入餐廳，并通過回風(fēng)機(jī)回到空調(diào)機(jī)；用兩臺(tái)機(jī)組分別為餐廳、廚房服務(wù)，其間廚房為全新風(fēng)直流系統(tǒng)，直接補(bǔ)償廚房爐灶的排風(fēng)。

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.
