1、 The diameter of the exhaust pipe is inconsistent with that of the range hood itself
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.
2、 The exhaust pipe should not be too long and bent too much
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%.
3、 The size of the range hood is smaller than that of the gas stove
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.
4、 Too many doors and windows near the installation position
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.
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.
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.
