Abstract:
1. A scroll compressor, comprising: a plurality of scrolls, which comprises a plurality of wraps engaged to each other, one of the plurality of scrolls performing an orbiting motion with respect to the other of the plurality of scrolls, thereby forming consecutively-moving compression chambers between the plurality of wraps; and at least one bypass hole that bypasses a portion of a refrigerant compressed in the compression chambers before the refrigerant reaches a discharge hole, wherein the at least one bypass hole is formed at a position where a wrap volume ratio (Vs/Vd), which is a ratio of a suction volume (Vs) with respect to a discharge volume (Vd), is within a range of about 1.8˜2.2 and wherein the at least one bypass hole is formed at a position where an overlapping section between a bypass section that bypasses the refrigerant through the at least one bypass hole and a discharge section that discharges the refrigerant through the discharge hole is implemented when a crank angle is within a range of about 20°˜150°.
