1, kitchen area

10㎡ closed kitchen, can I buy 15m per second? For a range hood with a displacement, if the kitchen area is below10m2, you can buy 17m per second. Exhaust hood. If the kitchen area is above10m2, can I buy 18-20m per second? Exhaust hood.

2. Practices and habits

If you have a large family, friends who often cook and like to stir-fry or stir-fry peppers, I suggest you buy 20-2 1m per second? The displaced range hood allows the kitchen fume to be discharged quickly. If you don't cook much and the taste is light, you can buy 18- 19m per second. The displacement of the hood, that's enough.

3. Floor conditions

On the lower floor, just buy 15- 17m per second? A hood with a displacement will do. If the floor is relatively high, it is recommended to buy 21m. Range hood, or buy an automatic supercharged range hood, so that there will be no problems such as oil fume backflow.

Note that the exhaust air volume should not be too large or too small. The exhaust air volume is small, the exhaust speed is slow, and the oil smoke is easy to spread around, which leads to the smell of oil smoke indoors. If the displacement is too large. The surrounding oxygen will be pumped away, which will not only affect the flame, but also take away the heat from the stove, which will slow down the cooking speed and make the food taste worse. Therefore, we should choose products with moderate exhaust capacity.
