Abstract (en)
To provide a scroll compressor which can reduce noise in a specific frequency range caused when a refrigerant mixture is used. A scroll compressor (1) of the present invention includes: a turning scroll (30) which is rotatably coupled with an eccentric pin (17A) of a main shaft (17); and a fixed scroll (20) which is opposed to the turning scroll (30) to thereby form a compression chamber for compressing a refrigerant and has an end plate in which a discharge port (23) for discharging the compressed refrigerant toward a high-pressure chamber (10B) is formed. The discharge port (23) is composed of an upstream port part (23A) which continues to the compression chamber and has an opening area (A1) and a downstream port part (33B) which continues to the upstream port part (23A) and has an opening area (A2) larger than the opening area (A1) of the upstream port part (23A), and a node of a vibration mode is generated at the border between the upstream port part (23A) and the downstream port part (23B).
