The principle structure, advantages and disadvantages of scroll refrigeration compressor

Principle: The scroll line pattern of the moving plate and the static plate are the same, but the phase difference is 180°C; they mesh to form a series of closed spaces; the static plate does not move, and the moving plate revolves around the center of the fixed plate with the eccentricity as the radius. When the moving disc revolves, it meshes in sequence, so that the crescent-shaped area is continuously compressed and reduced, so that the gas is continuously compressed and finally discharged from the center hole of the static disc
