AIR CONDITIONING SYSTEM FOR VEHICLE

An air-conditioning system for a vehicle includes an air-conditioning apparatus having a compressor 1 that compresses a first refrigerant 40 and a first heat exchanger 2 that exchanges heat between the first refrigerant 40 and external air and performing temperature regulation; and an equipment cooling apparatus that circulates a second refrigerant 41B between equipment 53, 54, 55 for electrically driving the vehicle and a second heat exchanger 7B to release heat absorbed from the equipment 53, 54, 55 to air in the vehicle interior in the heat exchanger 7B. The system further includes a heat-radiation suppressing structure 60 that suppresses heat dissipation from the equipment 53, 54, 55 to surrounding environment.
