An air conditioning system includes an air-cooling unit and an air-heating unit. On a first path in the cooling-unit, provided are a compressor for first refrigerant, a condenser for the first refrigerant, an expansion unit for the first refrigerant, and an evaporator to cool air. On a second path in the air-heating unit, provided are an air-conditioning radiator for second refrigerant, and a first valve for the second refrigerant (whether or not into the air-conditioning radiator) On a third path in the air-heating unit, provided are a driving-system heating element to heat third refrigerant, an internal heat exchanger to heat the third refrigerant, a heater core to heat air, a driving-system radiator for the third refrigerant, and a second valve for the third refrigerant (whether or not into the driving-system radiator). The air passing through the evaporator or the heater core is selectably sent into a vehicle compartment.
