A turbo machine of the present disclosure includes a rotation shaft, a first bearing, a casing, an impeller, a first space, a second space, a storage tank, a first outlet passage, a supply passage, a pump, a main passage, and a sub-passage. The second space is in communication with a space formed between a bearing surface of the first bearing and an outer surface of the rotation shaft. The main passage is in communication with the second space and extends in the rotation shaft from an end of the rotation shaft in an axial direction of the rotation shaft. The sub-passage is formed in the rotation shaft and allows communication between the space between the bearing surface of the first bearing and the outer surface of the rotation shaft and the main passage.

Turbo machine and refrigerating cycle apparatus

A turbo-compressor includes an impeller, a motor that generates heat by rotation and rotatably drives the impeller, a fluid passage through which a working fluid is forced by the impeller, and a heating mechanism that transfers the heat generated by the rotation of the motor to fluid upstream of the impeller so as to heat the working fluid at the inlet of the fluid passage.
