ABSTRACT:
There is provided a cooling apparatus which can improve a cooling efficiency while preventing an abnormal increase in pressure of a high side. The cooling apparatus comprises: a refrigerant circuit which uses carbon dioxide as a refrigerant; a control device which controls a speed of rotation of the compressor between predetermined lowest and highest speeds; and a cooled state sensor which detects a cooled state in a refrigerator main body to be cooled by an evaporator included in the refrigerant circuit. The control device increases a highest speed of rotation of the compressor if a temperature in the chamber of the refrigerator main body detected by the cooled state sensor is low.
