<p>The present invention relates to a turbo chiller. According to an embodiment of the present invention, the turbo chiller comprises: a turbo compressor compressing a coolant; a condenser condensing the coolant compressed in the turbo compressor; an expansion device reducing pressure of the coolant condensed in the condenser; an evaporator evaporating the coolant of which the pressure is reduced in the expansion device; and a liquid droplet supply pipe guiding the liquid coolant condensed in the condenser to the turbo compressor. The turbo compressor comprises: a first impeller and a second impeller compressing the coolant in multi-stages; and a return channel having a channel passage guiding the coolant compressed in the first impeller to the second impeller. The liquid coolant of the liquid droplet supply pipe is supplied to the channel passage of the return channel.</p> |
