<p>A centrifugal compressor with a high pressure fluid injection type capacity control device is provided to be simplified in structure since capacity control is accomplished by injecting high pressure fluid from a suction side to change flow of working fluid instead of using a guide vane. A centrifugal compressor with a high pressure fluid injection type capacity control device includes an impeller(10), a suction hole(2), at least one injection nozzle(100), a fluid supply, and a pressure control module. The injection nozzle is installed on the suction hole before the impeller crossing a flow direction of working fluid and injects high pressure fluid for changing the flow of the working fluid. The fluid supply supplies the injection nozzle with high pressure fluid. The pressure control module changes fluid supplied to the injection nozzle from the fluid supply.</p> |
