At present, the range hood products on the market are mainly divided into Chinese style, European style, and near suction type. Users often feel at a loss when choosing and purchasing. However, in fact, whether it is near-suction, Chinese-style or European-style hood, the key performance parameters are similar, and how consumers read the parameters becomes a necessary course. Air volume The “air volume†refers to the amount of exhaust air per unit time of the hood when the static pressure is zero. Under normal circumstances, the greater the value of air volume, the stronger the ability of the hood to suck and discharge fumes. Therefore, when the user selects a range hood, several similar products should choose products with larger air volume values. The index value is greater than or equal to 7m3/min, can give everyone a reference, some products even reached the air volume of 13 ~ 15m3/min, or even 18m3/min. Wind pressure After the air volume is finished, the air pressure is the next, and the air pressure is the static pressure value when the hood air volume is 7m3/min. The larger the air pressure value, the stronger the ability of the hood to resist the downwind. In the case of a long exhaust pipe, a product with a large air pressure can better ensure that fumes are completely discharged. Therefore, like the air volume, the larger the wind pressure, the better. Of course, as a reference, the state specifies that the value of this indicator is greater than or equal to 80Pa. noise Although this value of noise does not affect the performance of the hood, it also directly affects the user's experience in use. Needless to say, noise is of course the sound of the hood at the rated voltage and rated frequency, operating normally in the highest speed range. In the case of good performance, we certainly hope that the noise of the hood is as small as possible. It will not affect our good mood when cooking. The value of the index specified by the national regulations is not more than 74dB. Appliance owner Dongguan Best Instrument Technology Co., Ltd , https://www.best-tester.com
