초록 ▼

An internal combustion engine has a cylinder-head-passage through which an engine coolant flows toward a water jacket when a water pump is operated. The water pump is an electric water pump utilizing the electric power charged in the battery. A radiator is provided in the cylinder-head-passage. Even

대표청구항 ▼

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, andan electronic control unit comprising a processor and memory, whereinthe 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, andthe 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. 2. The air-conditioning system according to claim 1, wherein the electronic control unit is configured to control a temperature of the passenger compartment by adjusting the airflow which flows through the first and the second heater cores toward and into the passenger compartment. 3. The air-conditioning system of claim 1, wherein the electronic control unit comprises a first electronic control unit that is configured to control an electric motor and a second electronic control unit that is configured to control the first flow rate of the first coolant entering the first heater core and to control the second flow rate of the second coolant entering the second heater core, the first electronic control unit and the second electronic control unit each having a processor and memory. 4. The air-conditioning system of claim 1, wherein the electronic control unit is configured to control a first pump that sets the first flow rate of the first coolant entering the first heater core and is configured to control a second pump that sets the second flow rate of the second coolant entering the second heater core. 5. The air-conditioning system of claim 1, wherein a first coolant circuit connects the first coolant outlet to the first heater core, the first coolant passing through the first coolant circuit, and the first coolant circuit having a first hydraulic resistance,a second coolant circuit connects the second coolant outlet to the second heater core, the second coolant passing through the second coolant circuit, and the second coolant circuit having a second hydraulic resistance,the first hydraulic resistance being lower than the second hydraulic resistance, 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. 6. The air-conditioning system of claim 1, wherein the electronic control unit is configured to control a flow regulating valve 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. 7. The air-conditioning system of claim 1, wherein the automobile comprises the internal combustion engine and the electric motor, the internal combustion engine and the electric motor each being configured to transmit torque to wheels of the automobile, and wherein the electronic control unit is configured to control an electric motor to transmit torque to wheels of the automobile at a time when the internal combustion engine is stopped.
