Abstract
In a water discharge mode (heat storage mode) for discharging low-temperature cooling water from a heat storage tank to a side of a heater core that heats air using cooling water from an engine as a heating source, a cooling water amount discharged from the heat storage tank is made smaller as a necessary heating capacity for heating air becomes larger. For example, as an amount of air flowing through the heater core becomes larger, the cooling water amount discharged from the heat storage tank becomes smaller. Further, as the temperature of the cooling water flowing into the heater core becomes higher, the cooling water amount discharged from the heat storage tank is increased.
