Abstract
A cooling system includes: a compressor that circulates refrigerant; a heat exchanger that exchanges heat between the refrigerant and outside air; a cooling portion that uses the refrigerant to cool the heat generating source; a first line through which the refrigerant, which has been discharged from the compressor, flows to the cooling portion; a second line through which the refrigerant circulates between the heat exchanger and the cooling portion; and a selector valve that switches between fluid communication of the first line and fluid communication of the second line. A control device includes a detecting unit configured to detect an abnormality of the compressor; and a switching unit configured to switch the selector valve to interrupt the fluid communication of the first line and to allow the fluid communication of the second line when the abnormality has been detected by the detecting unit.
