Abstract
A turbo-compressor according to the present disclosure includes an impeller, a motor that generates heat by rotation of the motor and rotatably drives the impeller, a fluid passage through which a working fluid is passed via the impeller, and a heating mechanism that transfers the heat generated with the rotation of the motor to the fluid passage upstream of the impeller, to heat the working fluid inlet into the fluid passage with rotation of the impeller. The working fluid is compressed in the fluid passage downstream of the impeller.
Claims26
A turbo-compressor comprising:
- an impeller;
- a motor that generates heat by rotation of the motor and rotatably drives the impeller;
- a fluid passage through which a working fluid is passed via the impeller;
- and
- a heating mechanism that transfers the heat generated with the rotation of the motor to the fluid passage upstream of the impeller, to heat the working fluid inlet into the fluid passage with rotation of the impeller, the working fluid being compressed in the fluid passage downstream of the impeller.
A turbo-compressor comprising:
- an impeller that is rotatably driven by a motor;
- a casing that surrounds the impeller;
- a fluid passage that is partly constituted by the casing, a working fluid being passed through the fluid passage via the impeller;
- and
- a heating flow passage that transfers heat generated by a predetermined heat source to the fluid passage upstream of the impeller,
- wherein the heating flow passage is disposed in intersection relation to the fluid passage that is partly constituted by the casing,
- heat of the fluid supplied to the heating flow passage is transferred from an outer circumference of the heating flow passage to the working fluid flowing through the fluid passage constituted by the casing, and
- the working fluid is compressed in the fluid passage downstream of the impeller.
A turbo-compressor comprising:
- an impeller;
- a motor that rotatably drives the impeller;
- and
- a heating mechanism that heats the working fluid flowing toward the impeller by utilizing exhaust heat of the motor.
