SCROLL COMPRESSOR AND AIR CONDITIONING SYSTEM

Provided are a scroll compressor and an air conditioning system. A scroll compressor (100) includes a housing (11), a compression mechanism portion (12), a main frame (14), a motor (13), a crankshaft (16), a main balancing block (15), and an exhaust pipe (20). In a radial direction of the housing (11), the exhaust pipe (20) extends into the housing (11) at a depth W, and an outer peripheral wall of the main balancing block (15) is located at a distance L from an inner wall of the housing (11), where 0.47≤W/L≤0.93. In this way, a part of a high-pressure oil-gas mixture generated by the compression mechanism portion (12) is discharged through cyclone separation of the main balancing block (15) and mechanical separation of the housing (11), and the other part of the high-pressure oil-gas mixture flows into an axial channel such as a gap between a stator (132) and a rotor (131) to achieve oil and gas separation while cooling the motor (13), and then is discharged, reducing an oil circulation rate.
