Vortex compressor, air conditioner and vehicle

Abstract

The invention discloses a vortex compressor, an air conditioner and a vehicle. The vortex compressor comprises a back pressure cavity communicating with an exhaust cavity through an oil return channel. The back pressure cavity is provided with a pressure relief channel. The vortex compressor further comprises a pressure relief device used for opening or closing the pressure relief channel. When the oil pressure in the back pressure cavity is greater than a preset value, the pressure relief channel is opened by the pressure relief device so as to release the pressure. The pressure relief channel and the pressure relief device are additionally arranged so that when the pressure in the back pressure cavity reaches a certain value, the pressure relief channel can be opened to release the pressure in the back pressure cavity, the pressure is balanced, instability of the compressor caused by internal air flowing is avoided, the power of the compressor is reduced, the performance of the compressor is improved, noise and vibration of the compressor are reduced, and the problems that in the prior art, the pressure in a back pressure cavity is increased due to accumulation of refrigerant oilin the back pressure cavity, the pressure is imbalanced, and high power and large vibration and noise of the compressor are caused are solved.

Description

technical field [0001] The invention relates to the technical field of compressors, more specifically, to a scroll compressor, an air conditioner and a vehicle. Background technique [0002] Scroll compressor, because of its small size and high efficiency, has become the preferred compressor type in passenger cars. Existing scroll compressors such as figure 1 As shown, it includes a housing assembly 2, a bracket assembly 3, a moving disk assembly 4, a static disk assembly 5, a front cover assembly 6, a stator assembly 17, a rotor assembly 18, a crankshaft 19 and other components. When the compressor is working, the oil-air mixture enters the suction chamber 16 from the suction port 1, and then is discharged into the exhaust chamber 9 through the compression chamber 20, and the oil and gas are separated through the oil distribution pipe 8, and the gas is discharged from the exhaust port 7, and is refrigerated. After being filtered by the filter screen 11 , the oil 10 return...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a scroll compressor, an air conditioner and a vehicle to solve the problem of the accumulation of refrigerated oil in the back pressure chamber in the prior art, which causes the pressure in the back pressure chamber to rise, causing pressure imbalance and causing compressor failure. Problems of high power, high vibration and high noise
