▎ 摘　　要

NOVELTY - An air-conditioning filter assembly comprises a high efficiency and low impedance bacteria filter layer and a rhombic grid filter screen layer with the same projected area and arranged in order from the filter in to the filter out direction The bacteria filter layer comprises antibacterial mildew-proof filter support layer and a composite high-efficiency low-resistance electrostatic cotton filter layer. The antibacterial mildew-proof filter support layer comprises polymer fiber filament layer mixed with antibacterial mildew-proof filter nanoparticles in the fiber molecules. The needle-punched non-woven fabric is an electrostatic needle-punched non-woven fabric has been processed by high-voltage corona discharge. The surface of the rhombic grid filter screen layer is coated with nano silver paint. The rhombic grid filter layer comprises several longitudinally arranged aluminum strips, and several rhombic grids connected end to end are formed between two adjacent aluminum strips. USE - Filter assembly used for air-conditioning device (claimed). ADVANTAGE - The filter assembly has excellent efficiency and antibacterial properties, low filtering resistance, low cost maintenance, and can be washed repeatedly. DETAILED DESCRIPTION - An air-conditioning filter assembly comprises a high efficiency and low impedance bacteria filter layer and a rhombic grid filter screen layer with the same projected area and arranged in order from the filter in to the filter out direction The bacteria filter layer comprises antibacterial mildew-proof filter support layer and a composite high-efficiency low-resistance electrostatic cotton filter layer. The antibacterial mildew-proof filter support layer comprises polymer fiber filament layer mixed with antibacterial mildew-proof filter nanoparticles in the fiber molecules, and has a filament diameter of 2-4 mu m. The electrostatic cotton filter layer is needle-punched non-woven fabric with a weight of 30-50 g/m2. The needle-punched non-woven fabric is an electrostatic needle-punched non-woven fabric has been processed by high-voltage corona discharge. The surface of the rhombic grid filter screen layer is coated with nano silver paint. The rhombic grid filter layer comprises several longitudinally arranged aluminum strips, each strips are wavy, and several rhombic grids connected end to end are formed between two adjacent aluminum strips. The rhombic grids have side length of 5-7mm, and a depth of 7-8 mm. The aluminum strip has a width of 1-1.5 mm, and thickness of 0.5-1 mm. The cross section of the rhombic grid filter screen layer is wavy. The wave shape has a wave height of 18-22 mm and wavelength of 20-25 mm. An INDEPENDENT CLAIM is included for an air-conditioning device.
