Abstract

The invention discloses a centrifugal compressor which belongs to the technical field of compressors. The centrifugal compressor comprises a housing and a motor rotor arranged in the housing, whereinthe motor rotor is supported by a bearing; one end of the motor rotor is fixedly connected to a first centrifugal impeller; the gas inlet end of the first centrifugal impeller is opposite to the otherend of the motor rotor, and is connected to a gas inlet channel; a gas inlet of the gas inlet channel is positioned in the housing which corresponds to the other side of the motor rotor; and the gasinlet channel penetrates through the housing. With the adoption of the embodiment, the centrifugal compressor improves cooling efficiency of the motor rotor part, does not need extra cooling treatment, can reduce energy loss, and achieves the energy-saving high-efficiency purpose.

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, ...
