subject: Optional Hood Must See Several Important Indicators [print this page] At present, Range hood Is the most popular home users
Home Appliances Products. But how to choose good pumping performance
Hood , Is not able to answer each user. Here, the author provides several important advantages and disadvantages of indicators to measure range hood, range hoods for users to purchase reference.
1. Safety As household appliances, range hood's safety must be through the National Compulsory Certification (the "CCC" certification, ChinaCompulsiveProductCertification first initials), be listed
Sell . So you can rest assured their purchase without having to worry about security.
2. Use of performance Key is to understand their buying range hood performance, key performance indicators from the following to reflect.
1. Wind Wind is zero static pressure
Range Hood The exhaust volume per unit time. States require the index value greater than or equal to 7m3/min.
Shows that wind is a very important indicator. In general, wind-money, the more quickly in a timely manner to the kitchen a lot of smoke suction cleaner. So the user in the selection of hoods, when other indicators are a good case, as a large selection of wind hood value.
The way, how much wind is not like the design on how it is affected by many factors. Currently on the market of air flow hood to achieve 14m3/min already very good.
2. Pressure Wind pressure is the hood static pressure when the value for the 7m3/min. States require the index value greater than or equal to 80Pa.
Pressure is a measure hood performance is an important indicator. The larger pressure cooker hood lodging wind capability; if a longer exhaust pipe or flue in receiving the public, then the exhaust gas pressure loss greatly, thus requiring greater pressure to ensure that the smoke gas discharge. So, when other indicators are good cases, the greater the pressure the better the value.
Similarly, the same amount of pressure with the wind also affected by many factors.
3. Noise Noise is also an important value for the performance range hood specifications, it refers to the smoke machine at rated voltage, rated frequency, to a maximum speed of file operation, the required method of A measured sound power level. States require the index value is not greater than 74dB.
For this indicator, the user knows, the less noise the better.
4. Motor input power The general provisions of the model range hood CXW- - , where the first " " in the figure that is the main motor input power.
Understanding by the author, is now on the hood of the input power consumers have a misconception (which may be misleading due to some promoter), that the greater power of the better surely.
Is not true for three reasons: first, the manufacturer is to enhance the power of air volume and pressure to upgrade, if the air volume, air pressure is not improved, increase the power of any use? Second, the greater the power, the greater the possible noise. Third, electricity charges, the state is not to promote water saving it? What is more, obviously the input power is only 150W, obstinately above it marked the 200W.
More than a few indicators of the user so long as you can determine the merits of cooker hoods. There is also a leakage problem is also very important, but do not have an indicator to measure.
