The newly renovated living room must be equipped with a high-performance range hood, otherwise it will not only pollute the living room, but also bring health hazards to the cook. There are many types of range hoods in the market, and the functions are even more varied. When selecting, you should pay attention to suction, noise, energy efficiency, etc., so as to bring benefits to the living room and the environment.
Judging suction, seeing wind volume, wind pressure, and smoke
The main function of the range hood is to absorb soot. Suction is also one of the most important considerations for consumers to choose a range hood. Suction is not only a single look at the parameters of the range hood, but also three points that affect the suction of the range hood: air volume Wind pressure and smoke.
First of all, the air volume represents the suction and discharge of the hood wind in the unit time. At present, the national recommended standard requires a wind capacity of 10 cubic meters per minute for the hood. According to the cooking habits of Chinese families, the air volume is more suitable at 15 cubic meters per minute and above. Second, wind pressure represents the hood resistance
The strength of the downwind ability, that is, whether the soot can be smoothly discharged into the public flue when the peak season is cooked. At present, the national recommended standard for the hood is 80 Pa, but the problem of the Chinese public flue is more prominent. In general, the maximum wind pressure can be reached above 250Pa. Finally, the smoke represents the control ability of the range hood to the soot, mainly reflected in the smoke collecting chamber and the negative pressure zone of the range hood. Because the Chinese family prefers to stir-fry, a large amount of soot is generated instantaneously, and the range hood has a good smoke. Function to prevent the fumes from escaping.
Noise pollution affects the mood within 58 decibels
If the suction is better, if the noise is relatively large, it will greatly affect the mood of the cook, and it will not be good for the body for a long time. The noise represents the balance of the hood motor and reflects the overall quality of the hood. The current national standard for range hood noise is 59 decibels. Most of the range hood products on the market can control the noise within 58 decibels. The reason is that the range hood products often increase the oil absorption in order to absorb the fumes more quickly. The practice of the air volume of the hood, although the suction has gone up, has also brought about negative effects such as increased noise and rising energy consumption. How to do both to absorb the fumes and maintain a good environment for use, you need to look at the unit air volume noise value, the smaller the better.
Look at energy efficiency, look at the structure, choose a good hood
The energy efficiency is divided into 1~5 grades, and the first-level energy efficiency is the best. The products evaluated in one energy efficiency grade include a series of indicators such as full pressure efficiency, standby power, shutdown power, normal odor reduction, grease separation, etc. Power consumption, environmental protection, and soot absorption efficiency have a considerable reference. In addition, the structure design of the range hood should be easy to smoke and effectively remove grease and dirt, so as to achieve a smooth smoke exhaustion.
