Claim Text:
1. An air-conditioning system for an automobile, comprising a heat-exchanger for heating an air with a first coolant and a second coolant of an internal combustion engine, and an electronic control unit comprising a processor and memory, wherein the internal combustion engine includes a first coolant outlet through which the first coolant passed through a cylinder head flows out, and a second coolant outlet through which the second coolant passed through a cylinder block flows out, the heat-exchanger is comprised of a first heater core and a second heater core, the first heater core receives the first coolant from at least the first coolant outlet, the second heater core receives the second coolant from the second coolant outlet of which temperature is higher than that of the first coolant flowing into the first heater core, the second heater core is arranged downstream of the first heater core with respect to an airflow which flows through the first heater core and the second heater core toward and into a passenger compartment, the first coolant entering the first heater core from the first coolant outlet is fluidly independent from the second coolant entering the second heater core from the second coolant outlet, and the electronic control unit is configured to control a first flow rate of the first coolant entering the first heater core and to control a second flow rate of the second coolant entering the second heater core, such that the first flow rate received by the first heater core is greater than the second flow rate of the second coolant received by the second heater core.
