A few days ago, hefei general machinery products testing institute, the only authoritative organization of compressor energy efficiency testing and certification, conducted energy efficiency testing for the permanent magnet frequency conversion two-stage compression integrated air compressor of hand precision machinery co., LTD.
According to the provisions of the national standard "limited energy efficiency value and energy efficiency grade of positive displacement air compressor", the whole series of hande products have passed the China energy efficiency certification and obtained the level 1 energy efficiency certificate, and some products exceed the national level 1 energy efficiency.
According to the test, the actual unit input specific power of this compressor is 6.3, which exceeds the national energy efficiency of level 1 by 12.5%, level 2 by 22.3%, and level 3 by 29.3%.
At present, most of the same power units in the market are level 2 and level 3 energy efficiency products, which can completely replace the air compressor in service, saving users about 160000/ h of electricity per year. If the unit price of electricity is calculated at 0.8 yuan/h, the annual electricity saving is 128,000 yuan.
