Various types of range hoods on the market are easy to dazzle, but also make people unable to start. When you buy the right range hood, the family smoke exhaust is unobstructed and easy to take care of. I bought the wrong range hood. It's distressing to negotiate after-sales. Carefully observe various types of range hoods, air volume or suction mode, etc. range hoods have some common indicators. If you want not to choose the wrong range hood, you can generally grasp the performance of a range hood through the following multiple parameter indexes.

Exhaust air volume

Every time I go to the shop to buy, I always hear some experts ask "exhaust air volume", which refers to the exhaust air volume per unit time of the range hood when the static pressure is zero. In general, the exhaust air volume is directly proportional to the smoke absorption and exhaust of the range hood. The larger the exhaust air volume, the stronger the smoke absorption and exhaust capacity of the range hood, the smaller the exhaust air volume, and the smoke absorption and exhaust of the range hood will also be affected to a certain extent. Therefore, when purchasing range hood, products with large exhaust air volume can be considered. According to the national standard of not less than 13 m3 / min, the exhaust volume of most range hoods in the market can be 15-32 m3.

Intelligent remote control

With the development of artificial intelligence, the high requirements for science and technology also appear in the use of household appliances. Usually, when you have greasy hands and don't want to dirty the keys of the range hood, you can wave your hand in front of the range hood to realize the control of on-off and large air volume smoke exhaust, or voice wake-up the AI function of the range hood and dialogue to make the range hood realize smoke exhaust. This intelligent technology has long been developed and applied to multiple models of range hood in doublemax, intelligent remote control, Let life enjoy the convenience of science and technology.

Wind pressure

Air pressure and exhaust air volume are completely different concepts. Air pressure refers to the static pressure value of the range hood in the air duct. The static pressure value is directly proportional to the anti backflow air capacity of the range hood. The greater the static pressure value, the stronger the anti backflow air capacity of the range hood. Therefore, in addition to the exhaust air volume, the wind pressure factor should also be considered. The national standard is generally not less than 80pa. Now the wind pressure has generally increased. The wind pressure of many doublemax models can be in the range of 200pa-500pa. This is because high-rise buildings are public flues. The longer the flues, the greater the resistance of the air duct will be caused by bends. Due to the sharing of public flues in high-rise buildings, when the smoke exhaust volume of public flues increases, the wind pressure in the flue will increase significantly. Therefore, the wind pressure requirements for range hoods are also high. Users living in high-rise buildings should try to choose models with high wind pressure.

Noise

Although noise does not belong to the ranks of performance, it directly affects the user's sense of experience. When the range hood is turned on, the noise required by users generally does not affect the use. The national standard is that the noise is no more than 74 dB. Most of Sentai's range hoods are about 50-60db.

The above four factors are only used to judge whether part of the configuration of a range hood meets the ideal standard. Whether online or offline, the purchase must be comprehensively weighed, so as to select the product that meets your expectations.
