The range hood is a necessary kitchen appliance for every household, which effectively reduces the oil fume pollution and brings good news to housewives. Is the exhaust volume of the range hood good? Next, let's take a look at the related content about the large exhaust volume of range hoods.
at present, the exhaust air volume of range hoods is large in the market, so the exhaust air volume of range hoods is ≤11 m3 /min, 11-14 m3 /min, 15-17 m3 /min, 18-21 m3 /min and ≥21 m3 /min * *.
The exhaust air volume of the range hood is large. When the exhaust air volume of the range hood is too large, it will take away the surrounding oxygen and have a certain influence on the flame, and at the same time, it will take away part of the heat. At the same time, the exhaust air volume is too large, which has certain requirements for the motor of the range hood, so it increases the noise and affects the comfort of cooking. Generally speaking, anything exceeding 21 cubic meters is too large, and it is not recommended to buy it.
when the exhaust air volume of the range hood is too large, the exhaust speed of the range hood is too slow, or it is not clean. Generally speaking, the exhaust air volume is too small (excluding 14 cubic meters) when it is less than 1.4 cubic meters /min. It is not recommended to buy it, and with the increase of use time, the suction of the range hood will weaken, and the smoke will not be clean.
The "15m3/min" exhaust volume of a range hood is the "golden exhaust volume" of a range hood. This exhaust volume can not only effectively prevent the oil fume from flowing backwards in the public flue, but also fully meet the daily cooking needs of families in China. However, no matter how large the smoke volume is, the smoke absorption effect is not good, because when the lateral velocity of fresh air is much greater than the speed at which the smoke rises and is sucked into the hood, it will also lead to more air components than the smoke components, which will seriously disturb the flow direction of the smoke gas and cause the smoke to spread and escape. Therefore, it is necessary to choose a "golden" smoke exhaust volume, not the bigger the better.
