The invention belongs to the technical field of refrigeration equipment, and particularly relates to a scroll compressor, refrigeration equipment and a vehicle. The scroll compressor comprises an oil separation device provided with a shell and an oil separation insertion pipe, an oil separation cavity and an oil storage pool are arranged in the shell, the oil separation insertion pipe is arranged in the oil separation cavity, an oil discharge hole is formed in the cavity wall of the oil separation cavity, and a refrigerant outlet is formed in the shell. The overflowing area S1 of the refrigerant outlet, the overflowing area S2 of the air inlet end of the oil separation inserting pipe and the overflowing area S3 of the oil discharging hole meet the conditions that S2/S1 is larger than or equal to 0.05 and smaller than or equal to 0.5, and S3/S1 is larger than or equal to 0.02 and smaller than or equal to 0.3, so that the refrigerant is discharged from the refrigerant outlet at a high speed after being separated, the internal pressure of the oil separation cavity is rapidly reduced, the pressure acting on the refrigerant oil is reduced, and the pressure and the flowing speed when the refrigerant oil is discharged are reduced; and the impact on refrigeration oil in the oil storage pool is reduced, so that the oil return hole of the oil storage pool can be always immersed by the refrigeration oil, a refrigerant cannot leak through the oil return hole, the return oil of the compressor is sufficient, and a friction pair can be effectively lubricated.
本发明属于制冷设备技术领域,具体涉及一种涡旋压缩机、制冷设备及车辆。涡旋压缩机包括具有壳体和油分插管的油分装置,壳体内设有油分腔和储油池,油分插管设于油分腔内,油分腔的腔壁上设有排油孔,壳体上设有冷媒出口,冷媒出口的过流面积S1、油分插管的进气端的过流面积S2及排油孔的过流面积S3满足0.05≤S2/S1≤0.5、0.02≤S3/S1≤0.3,如此,冷媒分离后以较快速度从冷媒出口排出,油分腔内部压力快速降低,作用于冷冻油的压力降低,冷冻油排出时的压力及流速降低,对储油池内冷冻油的冲击降低,从而能确保储油池的回油孔始终被冷冻油浸没,冷媒不会通过回油孔泄露,压缩机回油充足,摩擦副能够得到有效润滑。
