Scroll compressor, refrigeration equipment and vehicle

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a scroll compressor, refrigeration equipment and a vehicle. Background technique [0002] The statements herein merely provide background information related to the present invention and may not necessarily constitute prior art. [0003] Scroll compressor is a volumetric compressor with high efficiency, low noise and stable operation. It is widely used in automobile air conditioning system as the third generation of on-board compressor. The requirements for noise, vibration and durability of air-conditioning scroll compressors are further improved. During the use of the scroll compressor, refrigeration oil needs to be provided to lubricate the friction pairs in the scroll compressor, so as to reduce the noise generated when the friction pairs work. In the prior art, an oil separation structure and an oil storage tank are arranged in the scroll compressor, the oi...

Problems solved by technology

[0005] The purpose of the embodiments of the present invention is to provide a scroll compressor, refrigeration equipment and a vehicle, aiming at solving the problem of scouring the frozen oil in the oil storage tank by the refrigerated oil discharged from the oil discharge hole of the oil separation structure of the scroll compressor in the prior art, As a result, the proportion of refrigerated oil in the return oil is reduced, resulting in the failure of effective lubrication of friction pairs, increased power consumption of scroll compressors, and reduced compression efficiency.
