1、 Orderly air supply shall be selected for kitchen air supplement

廚房補風有兩種，一種是無序送風，會造成廚房的工作環境惡劣。是在夏季，雖然餐廳內通常會安裝一些局部柜式空調機以降低餐廳的室內溫度，但室內空氣補入廚房，并不能廚房的熱負荷并降低廚房溫度。

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.

一種是有序送風，在廚房的通風系統中，多為以下三種補風方式：餐廳空調為全新風直流式空調系統，空調新風送入餐廳，然后流入廚房經排風系統排出室外；將組合式空調機組的新風一部分直接補入廚房，一部分送入餐廳，并通過回風機回到空調機；用兩臺機組分別為餐廳、廚房服務，其中廚房為全新風直流系統，直接補充廚房爐灶的排風。

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、合理安裝排煙管道

2、 Reasonable installation of smoke exhaust pipe

廚房排煙管道的水平段不宜太長，一般水平遠距離不應超過15m并且要有2%以上的坡度，水平末端設活接頭，以方便清理油垢。排風速度按規范不得低于 10m/s，以防風速過低使油附著于煙道上，接排風罩的支管應設風量調節閥。

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、合理使用排煙設備。

3、 Use smoke exhaust equipment reasonably.

廚房排煙設備要求其外型美觀大方，排煙效果好，能與不同風格的廚房家具裝修匹配等特點，使用方法如下：
