Title:

VEHICLE AIR CONDITIONING SYSTEM

Document Type and Number:

WIPO Patent Application WO/2012/114427

Kind Code:

A1

Abstract:

With the objective of efficiently performing in-cabin air conditioning and the cooling of a heat-releasing apparatus mounted in a vehicle, reliably causing the temperature of an apparatus-cooling medium to be no greater than a predetermined temperature, and preventing apparatus damage, this vehicle air conditioning system—which is provided with an apparatus-cooling circuit of the vehicle-mounted heat-releasing apparatus; a cabin-interior air conditioning device having a refrigeration cycle circuit; and an intermediate heat exchanger that exchanges heat between the apparatus-cooling medium of the apparatus-cooling circuit and an air conditioning cooling medium of the refrigeration cycle circuit—is characterized by causing the control period of the vehicle air conditioning system to be a short time period when the temperature of the cooling medium of the apparatus-cooling circuit becomes at least a predetermined temperature, the predetermined temperature being less than the maximum temperature of the apparatus-cooling medium and being determined from the heat capacity of the apparatus-cooling circuit and the heat capacity of the heat-releasing apparatus.
