Second, how to choose a range hood
1. Some manufacturers use some ferroalloys. The surface is covered with real materials by spraying or so-called baking process, and attention should be paid when buying. Stainless steel also has a thick layer, and of course the thickness will be better.
2. The gas collecting chamber of the oil lamp mainly forms a certain negative pressure at the exhaust port to form a smoke-closing effect. Generally speaking, the collection room of China Aircraft Corporation is relatively large, while the European Aircraft Corporation is slightly shallow. The suction type of near-suction middle plate adopts negative pressure net or circular smoking to achieve smoke collection effect, and because of its low installation height. Starting from soot, when soot is formed, soot begins to adsorb.
3. Wind pressure is an important index to measure the performance of range hood. The greater the wind pressure, the stronger the anti-winding ability of the range hood; If the exhaust pipe is long or connected to the public flue, the exhaust pressure will be greatly lost, so greater wind pressure is needed to ensure the exhaust of flue gas. Therefore, when other indicators are good, the greater the wind pressure value, the better.
4. For traditional Chinese or European engine hoods, oil filters are square, diamond, round, strip and so on. Each oil filter has its length to filter oil fume and prevent oil droplets. However, as we all know, the oil is sticky and the grid is too small to stop, which affects the suction. Moreover, due to the manufacturing process, the overall rigidity of the oil net is insufficient, and it is easy to sag and not easy to clean.
5. Air volume: When the static pressure is 0Pa, there are no other obstacles. The gas quantity delivered by the range hood per unit time is-,which means the air quantity per unit time when the range hood works, and the unit is m3/min.
6. Noise: refers to the maximum noise of the engine hood when it runs in different gears, in dB. Generally speaking, the noise of the engine hood runs at the maximum power, the sound power level does not exceed 70dB, and the sound pressure level does not exceed 56dB.
7. Energy efficiency grade: a classification method to indicate the energy efficiency difference of electrical products. According to the relevant provisions of national standards, China's energy efficiency labeling currently has five levels of energy efficiency. Grade 1 indicates that the product has reached the international advanced level and the energy consumption is the lowest.
