Introduction: Range hood is an indispensable electrical appliance in the kitchen, and its air volume directly affects the emission effect of oil smoke.
So, when choosing a range hood, which parameter should we pay attention to to judge its air volume? This article will give you a detailed analysis.
First, the importance of the air volume of the range hood
During cooking, oil fumes are unavoidable.
The function of the range hood is to discharge the oil smoke generated outside in time to keep the kitchen air fresh.
Air volume is an important indicator to measure the ability of the range hood to discharge fume, the larger the air volume, the better the effect of emitting fume.
Second, the key parameter: exhaust air volume
Exhaust airflow refers to the volume of air emitted by the range hood per unit time, which is usually expressed as "m3/min".
The exhaust air volume is the core parameter to measure the air volume of the range hood, and it is also the data we need to pay attention to when selecting the range hood.
1. National standard: According to the relevant laws and regulations of the mainland, the exhaust air volume of the range hood should be greater than or equal to 7m3/min.
When purchasing, consumers should ensure that the exhaust air volume of the selected product meets this standard.
2. Market status: At present, the exhaust air volume of range hoods on the market is mainly concentrated between 7-14m3/min.
The product with an exhaust air volume of 14m3/min has an excellent effect on emitting oil smoke.
3. How to choose: When purchasing a range hood, if other performance indicators are similar, it is recommended to choose a product with a large exhaust air volume.
However, it should be noted that the larger the exhaust airflow, the better, and excessive exhaust airflow may lead to increased energy consumption and noise.
3. Other relevant parameters
1. Wind pressure: Wind pressure refers to the static pressure value of the range hood when the exhaust air volume is 7m3/min, and the unit is "Pa".
The higher the wind pressure value, the stronger the range hood's ability to resist backwind.
When the exhaust pipe is long or connected to the public flue, the large air pressure can ensure the smooth discharge of the fume.
2. Noise: Noise is another important indicator to measure the performance of a range hood.
The state stipulates that the sound power level of A when the range hood is running in the highest speed gear should not be greater than 74dB.
When purchasing, it is recommended to pay attention to products with low noise.
3. Motor input power: The motor input power of the range hood is not as large as possible.
Increasing the power is mainly to increase the air volume and wind pressure, if the air volume and wind pressure are not improved, increasing the power will not help.
Fourth, summary
When selecting a range hood, consumers should pay attention to the key parameter of exhaust air volume.
On the basis of meeting the national standards, choose products with moderate exhaust air volume, large wind pressure, low noise and suitable motor input power.
It is also necessary to consider factors such as the style, appearance, and ease of cleaning of the range hood, and comprehensively choose the most suitable product for yourself.
