The energy efficiency rating is the energy efficiency ratio. Level 1 has the highest energy efficiency and the most energy-saving, level 2 is second, and so on! The energy efficiency label is an information label attached to a product, which is used to indicate the energy efficiency grade and energy consumption of energy-using products.
At present, more than 100 countries have implemented energy efficiency labeling systems. It is a color logo with a blue and white background. The energy efficiency rating of the air compressor is divided into three levels, 1, 2, and 3. Level 1 means that the product has reached the international advanced level, with the most energy-saving, that is, the lowest energy consumption; Level 2 means more energy-saving; Level 3 means that the energy efficiency of the product is the average level of the Chinese market; the energy efficiency label is a color label with a sticky back and the word "CHINA ENERGY LABEL" on the top, which is generally pasted on the front panel of the product. The information content of the compressor energy efficiency label includes the manufacturer, model, energy efficiency grade, input specific power, and the national standard number based on 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 for consumers. Recent research results show that the formulation and effective implementation of new energy efficiency standards and energy labels will improve the energy efficiency of products and consumers’ awareness of energy conservation.
For example: According to the air compressor running for 8000 hours a year, the industrial electricity consumption 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)
Purdue 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, the same 18.5KW air compressor runs 8000 hours a year,
The first-level energy-efficient air compressor saves 29,304 yuan in electricity costs than the second-level energy-efficient air compressor.
If you are using an 18.5KW secondary energy-efficient screw air compressor, then in the first year that the screw air compressor is put into use, your electricity bill will exceed the purchase cost you paid for the screw air compressor. Therefore, it is very important to reduce the operating cost of air compressors, and the key is to save energy. Therefore, air compressors are worthy of serious consideration when purchasing.
