Abstract
A scroll compressor is provided, in which at least one bypass hole that bypass a portion of a refrigerant before the refrigerant is discharged through a discharge hole is formed at a position where a bypass section that bypasses the refrigerant through the at least one bypass hole overlaps a discharge section that discharges the refrigerant through the discharge hole. 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) in a compression chamber, is within the range of about 1.8˜2.2. With this configuration, over-compression of refrigerant may be prevented in a low speed driving mode, and efficiency of the compressor may be enhanced in the low speed driving mode and under a low load condition.
