Claim 0:
1. A control device for controlling, in response to an air-conditioning request and a battery cooling request, a drive state of a compressor that compresses a refrigerant and is included in an air-conditioning refrigerant circuit of a vehicle-mounted cooling system, the air-conditioning refrigerant circuit including, in addition to the compressor, a refrigerant passage in which the refrigerant circulates, a heat source-side heat exchanger, and a use-side heat exchanger, the vehicle-mounted cooling system including, in addition to the air-conditioning refrigerant circuit, a battery that supplies power to a vehicle-mounted electric component, and a battery cooling unit that cools the battery using the refrigerant circulated in the refrigerant passage,
the control device comprising:
an abnormality determination unit configured to determine whether an abnormality has occurred in the air-conditioning refrigerant circuit; and
a control mode change unit configured to perform, under a situation where the battery cooling request has occurred and it is determined that an abnormality has occurred in the air-conditioning refrigerant circuit, a change of a refrigerant-circulation control mode while permitting the battery cooling unit to continuously cool the battery based on the circulated refrigerant, the refrigerant-circulation control mode representing how the refrigerant is circulated in the air-conditioning refrigerant circuit, wherein
the control mode change unit is configured to perform, as the change of the refrigerant-circulation control mode, restriction of a rise in a pressure of the refrigerant in the refrigerant passage as compared with before it is determined that an abnormality has occurred.
