Abstract
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.
