Now when shopping for a range hood in a shopping mall, many shopping guides will put up the banner of "grease separation", claiming that such a range hood is more scientific, reasonable, healthy and environmentally friendly, and the cleaning and maintenance are more convenient and quick, and the range hood with "grease separation" has a longer service life. Consumers are dizzy and don't know whether to choose such a range hood. In fact, the technology of oil separation in range hoods has become a trend of science and technology, and oil separation is indeed more scientific. In fact, there is also a degree of oil separation of range hoods. So, how much is the degree of oil separation better? Let's take a look at the oil separation degree of the range hood now.
what is the oil separation degree?
before we know how much the oil separation degree of the range hood is better, let's know what the oil separation degree is. The so-called grease separation degree refers to the ability of a range hood to separate grease from lampblack gas under specified test conditions, which is a performance index written in GB/T 17713 "Range Hood" together with the normal odor reduction degree in 2111. According to GB/T 17713-2111 "range hoods", the oil separation degree of the exhaust range hoods should not be less than 81%. The oil separation degree has become an important content of the energy efficiency label of range hoods, which means that in addition to meeting the index requirements of the energy efficiency standard of range hoods, the oil separation degree of products on the market must meet the relevant provisions of GB/T 17713-2111 Range Hoods, that is, it must not be less than 81%.
What is the effect of oil separation degree of range hood on range hood
1. It affects the effect of range hood
The concept of oil separation degree is not abstract. For example, if the oil separation degree is high, the oil fume will separate the oil from the oil fume and collect it in the oil cup, while if the oil separation degree is too low, it will lead to too much oil deposition in the machine, which is not easy to clean.
In addition to the oil smoke separation degree, many consumers mistakenly think that the "suction" of the range hood has a great influence on its effect, but it is not. There are four main factors that really affect the effect of the range hood: air volume, noise, odor reduction and oil separation degree. They can all be seen in the product manual. The values such as 15, 16, 17 that salespeople hear the most generally refer to the air volume, and its unit is "cubic meter/minute". At present, the air volume of domestic range hoods is generally between 1.5 cubic meters per minute and 21 cubic meters per minute, and some manufacturers will achieve more than 21 cubic meters per minute.
2. It is closely related to the price
In fact, the oil separation degree is closely related not only to the efficacy of the range hood, but also to the sales price of the product. Five energy efficiency grades of range hoods are specified in the standard "Limits and Grades of Energy Efficiency of Range Hoods". Among them, the market entry threshold is energy efficiency level 5, and energy efficiency level 1 is the highest level. The energy-saving evaluation value of the range hood is energy efficiency level 2, and the products that reach this level are recognized as energy-saving products. We can understand that the higher the energy efficiency level of oil separation of range hoods, the more energy saving, the more advanced the technology used in manufacturing, and the higher the price naturally. This is the price difference.
How appropriate is the oil separation degree: not less than 81%
The oil separation degree of the range hood directly affects the key index of the oil fume accumulation degree inside the machine. When cooking, the oil fume will not only be discharged outside with the flue, but also more oil will be hidden inside the machine and finally put into the oil box. The oil separation degree is an important index to measure the oil separation ability inside the machine. The higher the degree of separation, the less grease accumulates inside the machine.
that's all I've introduced to you about how good the oil separation degree of range hoods is. I hope it will help you. With the maturity of the oil separation technology of range hoods, more and more range hoods may use this technology. When we choose, we will also hear more shopping guides to describe the functions of range hoods to consumers. I hope everyone will have a deeper understanding of the concept of oil separation after reading the above contents.
