When users buy air compressors, the first thing they should consider is the production cost of compressed air. The production cost of compressed air consists of the following three aspects: the purchase cost of the air compressor; the repair and maintenance cost of the air compressor; and the energy cost (electricity cost). Among them, the electricity cost accounts for more than 80% of the total production cost. This article briefly discusses the energy efficiency rating of screw air compressors. The energy efficiency rating is the energy efficiency ratio, with level 1 being the highest and most energy-saving, level 2 being the second, and so on!
The energy efficiency label is an information label attached to the product, which is used to indicate the energy efficiency level, energy consumption and other indicators of energy-using products. At present, more than 100 countries have implemented the energy efficiency labeling system. It is a color label with a blue and white background. The air compressor energy efficiency rating is divided into 3 levels: 1, 2, and 3. Level 1 means that the product has reached the international advanced level and is the most energy-saving, that is, the lowest energy consumption; level 2 means relatively energy-saving; level 3 means that the energy efficiency of the product is at the average level of the Chinese market. The energy efficiency label is a color label with an adhesive back and the words "CHINA ENERGY LABEL" on the top. It is usually affixed to the front panel of the product. The information content of the compressor energy efficiency label includes the manufacturer, model, energy efficiency level, input specific power, and national standard number of the product. Energy efficiency standards and energy efficiency labels have been proven to be the most cost-effective way to reduce energy consumption. At the same time, they will bring huge environmental benefits and provide positive returns to consumers.
Recent research results show that the formulation and effective implementation of new energy efficiency standards and energy labels can improve the energy efficiency level of products and consumers' energy-saving awareness. Take an example as follows:
The air compressor runs for 8000 hours a year, the industrial electricity is calculated at 1 yuan/kWh, the motor power is 18.5KW, the exhaust volume is 3.33m3/min, and the exhaust pressure is 0.8MPa
(Air-cooled) The unit input specific power is 7.3 KW/(m3/min)(Level 1 energy efficiency)
(Level 2 energy efficiency) 8.4-7.3(Level 1 energy efficiency)]×3.33(exhaust volume)×8000(hours)=29304(yuan)
That is to say, for the same 18.5KW air compressor running for 8000 hours a year, the first-level energy efficiency air compressor saves 29304 yuan in electricity bills than the second-level energy efficiency air compressor.
If you use a 18.5KW second-level energy efficiency screw air compressor, then in the first year of the screw air compressor being put into use, the electricity bill you pay exceeds the purchase cost of the screw air compressor. Therefore, it is very important to reduce the operating cost of the air compressor. The key is energy saving, which is worth your serious consideration.
In the future market, energy-saving air compressors will definitely become the mainstream products in the market, energy-saving China. Policies will also tend to develop and support energy-saving products, so choosing high-quality, high-energy-saving products must be correct. Shanghai Rodecom Screw Compressor Co., Ltd., as a company that has been operating compressors for many years, has also developed its own new products, LBB/LGB series of high-efficiency energy-saving micro-oil screw compressors, LGFD/LGD series of high-efficiency energy-saving micro-oil screw machines, high-efficiency energy-saving NK/B series twin screw machines, high-efficiency energy-saving D series twin screw machines, high-efficiency energy-saving second-generation LGFD series twin screw machines, high-efficiency centrifugal air compressors. Any series can be a candidate for replacement in the new year.
