A turbo compressor has a plurality of stages of compression means, each including an impeller and a diffuser, arranged in tandem with the flow of a fluid, and is capable of compressing the fluid sequentially in a plurality of the compression means and supplying the fluid compressed in the compression means in a final stage to a condenser. The diffuser of at least the compression means in the final stage is a vaneless diffuser which does not include diffuser vanes which reduce the turning speed of the fluid in the diffuser. As such, according to this turbo compressor, it is possible to reduce generation of noise resulting from the transmission of turbulence of the fluid to the condenser, which occurs as the refrigerant collides against the diffuser vane. |
