Abstract

The invention provides a centrifugal compressor. The centrifugal compressor comprises a motor, a first compressor and a second compressor, wherein the motor comprises a cylinder body, a first output end and a second output end; the cylinder body is provided with a first end and a second end which are oppositely arranged; the first output end and the second output end are respectively arranged at the first end and the second end; the first compressor is arranged at the first output end of the motor; the second compressor is arranged at the second output end of the motor; and an outlet of the first compressor is communicated with an inlet of the second compressor. The centrifugal compressor directly drives impellers of the first compressor and the second compressor to rotate at high speed, so that a gear speed-increasing structure is eliminated, the centrifugal compressor has the characteristics of small size and light weight, meanwhile, mechanical loss and noise caused in a driving process of the gear speed-increasing structure are also avoided, a sound isolating device for reducing the noise can also be eliminated, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of air conditioners, and more specifically, to a centrifugal compressor. Background technique [0002] Centrifugal compressors in the field of air conditioning in the prior art usually use fixed-frequency AC motors or variable-frequency AC motors, and the speed is increased to the design speed through the speed-increasing gear to drive the impeller of the compressor to rotate, so that the high-speed rotating impeller does work on the incoming gas. , thereby increasing the gas pressure. [0003] This compressor structure in the prior art has the following disadvantages: (1) due to the use of speed-increasing gears, the mechanical loss of the centrifugal compressor is increased, thereby increasing the power consumption of the centrifugal compressor and affecting the centrifugal compressor. The performance of the unit; (2) The existence of the speed-increasing gear greatly increases the shape and structure of the centri...
