る。As described above, according to the first and second aspects of the present invention, when immediate heating is instructed by the immediate heating instructing means, the temperature of the air passing through the heating radiator reaches a predetermined temperature. Since the amount of cooling water flowing into the radiator through the heat storage tank is set to a predetermined flow rate, that is, a relatively large flow rate, the high-temperature cooling water in the heat storage tank reaches the radiator in a short time and reduces the temperature of the blown air. A predetermined temperature can be reached in a short time.

The ratio of the amount of heat given to the air passing through the radiator to the amount of heat of the cooling water flowing into the radiator can be increased as compared with the case where the predetermined flow rate is set.
That is, the difference in heat quantity of the cooling water between the inlet and the outlet of the radiator can be increased. Therefore, the heat of the cooling water in the heat storage tank can be used as much as possible for heating the vehicle interior.
