Abstract
A cooling system comprising a cooling water circuit in which cooling water of an engine circulates in a radiator , a hot water circuit in which hot water circulates in a heater core , an air mixing door for adjusting the volume of air which passes through the heater core, a heat storage element provided in a bypass passage for branching hot water into the heat core from the hot water circuit, a flow path selector valve for adjusting the distribution of hot water to the heat storage element and the heater core, and a control unit for controlling the operation of the air mixing door and the flow path selector valve, wherein the control unit controls the flow path selector valve such that the flow rate of hot water to be distributed to the heater core becomes larger than the flow rate of hot water to be distributed to the heat storage element, in the event that the volume of air passing through the heater core is equal to or larger than a predetermined value.
