Rolling rotor type and centrifugal composite compressor

The invention provides a rolling rotor type and centrifugal type compound compressor which comprises a rolling rotor pump body and a centrifugal pump body, the rolling rotor pump body is located in a shell and provided with an upper cylinder cover, the upper cylinder cover is provided with an exhaust valve, and a crankshaft is arranged in the rolling rotor pump body; an impeller, a volute and a straight shaft are arranged in the centrifugal pump body, the straight shaft is connected to the impeller, an outlet of the impeller is communicated to the volute, and an outlet of the volute is communicated with the outside of the shell; the motor comprises a stator and a rotor and is located between the centrifugal pump body and the rolling rotor. The refrigerating capacity and the heating capacity of the compressor can be improved, the entropy increase and the exhaust temperature are reduced, the pneumatic design is simplified, and modularization of the centrifugal pump body is achieved. 本发明提供了一种滚动转子式及离心式复合压缩机，包括滚动转
