Vehicle thermal management system

A vehicle thermal management system mounted on a vehicle that travels by supplying electric power of a battery to a drive device, the vehicle thermal management system comprising:

• a refrigerant circuit including a compressor that compresses a refrigerant, an outdoor condenser into which the refrigerant compressed by the compressor flows, and a chiller expansion valve that expands the refrigerant flowing out of the outdoor condenser;
• a chiller connected between the chiller expansion valve and the compressor in the refrigerant circuit;
• a first circuit that is configured to allow a heating medium to flow therethrough and perform temperature adjustment of the battery using the heating medium flowing therethrough;
• a second circuit that is configured to allow the heating medium to flow therethrough and perform temperature adjustment of the drive device using the heating medium flowing therethrough;
• a third circuit that is configured to allow the heating medium to flow therethrough, the third circuit including a radiator that causes the heating medium flowing therethrough to exchange heat with outside air;
• a fourth circuit that is configured to allow the heating medium to flow therethrough, the fourth circuit being connected to the chiller;
• and
• a control unit that causes battery cooling in which the first circuit and the fourth circuit are connected and drive device cooling in which the second circuit and the third circuit are connected to be executed, the control unit being configured to, during the execution of the battery cooling and the drive device cooling, execute a heat absorption inhibition control that inhibits heat that has dissipated from the outdoor condenser from being absorbed by the radiator.
