The invention discloses a centrifugal compressor, and belongs to the technical field of compressors. The centrifugal compressor comprises a shell and a motor rotor in the shell. The motor rotor is supported by a bearing. One end of the motor rotor is fixedly connected with a first centrifugal impeller, and the other end of the motor rotor is fixedly connected with a second centrifugal impeller. The air inlet end of the first centrifugal impeller is arranged towards the air outlet end of the second centrifugal impeller. The air inlet end of the first centrifugal impeller and the air outlet endof the second centrifugal impeller are connected through an air inlet channel. The air inlet channel penetrates through the shell and is located between the shell and the motor rotor. By adoption of the embodiment, the motor rotor part cooling efficiency is improved, additional cooling treatment does not need to be adopted, energy losses can be reduced, and the purposes of energy saving and high efficiency are achieved.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a centrifugal compressor and a heat pump system. Background technique [0002] A centrifugal compressor is an important component of a heat pump system. The centrifugal compressor drives the impeller to generate pressure through the high-speed rotation of the motor. [0003] Heat will be generated under the high-speed rotation of the centrifugal compressor. When the heat reaches a certain level, it will often cause damage to the motor. The existing technology often adopts additional cooling medium, or additional cooling methods such as air cooling, so as to achieve The purpose of cooling the motor, but this method has a high cost and a large energy loss. Contents of the invention [0004] An embodiment of the present invention provides a centrifugal compressor and a heat pump system. In order to provide a basic understanding of some aspects of the disclosed embodiments, ...
