To provide a refrigerating apparatus capable of achieving suitable oil quantity control.
The refrigerating apparatus 1 includes a cooling medium circuit 10 for performing refrigeration cycle operations using carbon dioxide as a cooling medium. The cooling medium circuit 10 includes: a compressor 11 having oil stored in a case 12 and discharging the cooling medium with the oil to a high-pressure ejection pipe 21; an oil separator 22 arranged in the high-pressure ejection pipe 21; and an oil returning pipe 28 for returning the oil into the case 12, the oil having been separated by means of the oil separator 22. The apparatus also includes: an oil level sensor 31 for detecting an oil level in the compressor 11; and a display panel 51 for displaying a state of the oil level in the compressor 11 on the basis of detection signals obtained from the oil level sensor 31.
