The vehicle air conditioning system includes: a refrigerant circuit; a heat medium circuit including high-temperature medium and low-temperature medium circuits; interior and exterior heat exchangers; an exhaust heat recovery circuit; and a switching part. The system operates in: a mode in which the heat medium in the high-temperature medium circuit is supplied to the interior heat exchanger and exhaust heat from onboard equipment is recovered by the heat medium in the low-temperature medium circuit, while the heat medium recovered and transferred exhaust heat to the refrigerant is supplied to the exterior heat exchanger; and another mode in which the heat medium in the high-temperature medium circuit is supplied to the interior heat exchanger and exhaust heat from onboard equipment is recovered by the heat medium in the low-temperature medium circuit, while the heat medium recovered and transferred exhaust heat to the refrigerant is caused to bypasses the exterior heat exchanger.
