The vehicle is further provided with a duct for discharging air into a cabin of the vehicle for controlling the temperature of the air as discharged. A heater core is arranged in the duct for heating the air passing through the duct. A sensor 9 is provided for detection of the temperature of the cooling water of the engine. When the vehicle is operated by the electric motor, the heat taken from the engine cooling water is supplied to the heat exchanger for heating the air passing through the duct when the temperature of the engine cooling water is higher than a predetermined value.
