Provided is a multistage compression type refrigeration cycle device. When a control device (50) starts the multistage compressive refrigeration cycle device, a low-pressure side compression mechanism (1) and a high-pressure side compression mechanism (2) starts running at a lower rotation speed relative to a maximum rotation speed for exerting a maximum capacity, and the rotation speed goes up in stages. Therefore, oil can be inhibited from flowing out of a compressor. |
