We all know a range hood can keep cooking smoke, odor, and grease out of your kitchen. It improves our indoor air quality and cooking experience. But many people don't know what kind of range hood is best for them and don't know how to choose. So this article, we will talk about how to analyze the range hoods you need to buy from the following aspects. I hope it can help you to choose the right range hood you are satisfied with.
Factors that affect the smoke extracting effect of the range hoods:
- Extraction capacity and air pressure
These are two crucial indexes of range hoods, and large air extraction capacity is the main focus of current range hood companies' pursuit and promotion. Air volume is an essential indicator of the range hood's removal of oil fumes. The larger the air volume, the greater the amount of air that can be discharged outdoors per unit time under the same conditions.
The wind pressure (static pressure when the air volume is specified) is the range hood's ability to resist the air duct's resistance. The greater the wind pressure, the stronger the ability to resist the resistance of smoke exhaust. According to the test results, the air volume and pressure of the side suction range hood are slightly higher than that of the top suction range hood.
- Air volume
Although the high air volume can increase the exhaust rate of oil fume, it will also cause a drastic change in the room temperature, especially in winter and summer, which will cause the indoor heating or air conditioning to be exhausted and wasted. On the other hand, in the actual use environment, the pressure in the flue, the reverse air, the length and bending times of the smoke exhaust hose, and the use of a range hood, opening the window will produce smoke exhaust resistance. If you want to resist these resistances, you need to The range hood has an intense wind pressure. If the wind pressure is insufficient, even if the nominal air volume is large, the actual air volume will be seriously attenuated.
- Odor reduction
Immediate odor reduction is to assess the ability of the range hood to reduce the dirty air in the room in a short time. According to the test, the higher the value of the immediate odor reduction, the better the effect of absorbing oil fume in a short time.
How to choose a range hood?
- Check the motor, fan blades, and running noise
- The motor is the essential part of a range hood. When choosing a range hood, pay attention to the motor with ball bearing so that the motor service life will be longer. It is necessary to choose blades with non-stick metal treatment. Such blades are robust and durable, with stable dynamic balance, which is more conducive to separating oil and fume. It is necessary to press the power switch of the range hood repeatedly and compare the noise when the motor is started and the noise at work.
- The number of fans
Most range hoods have one fan, but some range hoods have two fans. In fact, whether it is two or one fan, the exhaust gas goes through a flue. If two fans work together, because the rotation speed cannot be kept exactly the same, the airflow generated by the two fans will cross each other and collide with each other, and cause energy waste. Therefore, the number of fans is not the more, the better, and one fan would be enough.
- The suction ability
The power of suction ability is directly related to the exhaust rate of the range hood, which is determined by the design of the air outlet, the internal fan structure, and the air intake design of the range hood. The easiest thing to do when we test is to use a certain amount of objects, such as paper, to check if it will be adsorbed on the air inlet. Don't just touch it with your hands.
- Cleaning ability
In regular use, the range hoods quickly get dirty and greasy. The oil stain will absorb dust and stick on the range hood, which not only affects the hygiene and appearance but also has different effects on the daily work and service life of the range hood. Therefore, it is very important for us to pay attention to the cleaning ability of the range hood when choosing. At this point, the manufacturers have spent a lot of effort. For example, the surface of the impeller is treated with a non-stick oil layer and with a double oil circuit design; or add a slanted oil spill slot so that the oil accumulated on the inner wall of the hood flows out along the slot hole, and the grease separated from the fan centrifugally flows through the oil drip hole. The central part of the range hood uses an elastic connection, which is convenient for disassembly and assembly and easy to clean.
These are the main aspects analyzed of choosing a range hood. Hope You have a better understanding of the range hood now, and you can choose a suitable range hood for your kitchen.
