Abstract

The invention provides a centrifugal compressor and an air conditioner provided with the same. The centrifugal compressor comprises centrifugal impellers, sealing rings and annular structures. Each centrifugal impeller comprises a first end plate, a second end plate and blades arranged between the first end plate and the second end plate. A refrigerant inlet is formed in each first end plate. A refrigerant outlet is formed between the circumferential edge of each first end plate and the circumferential edge of the corresponding second end plate. Each sealing ring is arranged on the circumferential outer side of the corresponding first end plate and sealed in the position of the corresponding refrigerant inlet. Each annular structure is arranged on the side, facing the corresponding second end plate, of the corresponding sealing ring. A buffer cavity is formed between each annular structure and the corresponding first end plate. By the adoption of the technical scheme, the problem that in the prior art, the axial force borne by a rotor of a centrifugal compressor is large is solved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a centrifugal compressor and an air conditioner with the same. Background technique [0002] When the centrifugal compressor is running, it creates a pressure differential within the centrifuge system. Specifically, the refrigerant enters the centrifugal impeller from the front end and is discharged from the side of the centrifugal impeller. Since the pressure of the refrigerant leaving the impeller is greater than the pressure of the refrigerant entering the impeller, the refrigerant will flow into the front end plate of the centrifugal impeller along the pressure difference and exert pressure on the front end plate. Under the action of the above pressure, the rotor of the motor will be subjected to an axial force, which will cause the compressor to deviate in the axial direction during operation. [0003] In the prior art, in order to prevent the rotor from be...
