Abstract:
A vehicular air-conditioning system includes: a vehicle interior air-conditioning apparatus which includes a device cooling circuit of a heat generating device mounted in a vehicle, and a refrigeration cycle circuit; and an intermediate heat exchanger for heat exchange between a device cooling medium of the device cooling circuit and an air-conditioning cooling medium of the refrigeration cycle circuit. A vehicle control apparatus is configured to determine a temperature of the cooling medium, and select a shorter control cycle timing of the vehicular air-conditioning system when the temperature of the cooling medium is greater than a predetermined temperature.
