COOLING SYSTEM FOR A MOTOR VEHICLE

s A cooling system of a motor vehicle includes a first cooling circuit and a second cooling circuit. A refrigerant circuit supplies a vaporizer associated with the first cooling circuit that has a first target power value (S) determining a cooling potential. The refrigerant circuit also supplies a refrigerant-coolant heat exchanger associated with the second cooling circuit that has a second target power value (S) determining a cooling potential. A conveyor unit controls a mass flow of a refrigerant flowing through the refrigerant circuit and can be controlled by the first target power value (S). The cooling system includes a control unit by way of which the first target power value (S) can be controlled to achieve the second target power value (S).
