The cooling system (1) has cooling medium circuit (2) for guiding a coolant. A cooling unit is provided to remove heat generated during operation of several components. A refrigerant circuit (3) is provided to guide refrigerant to condenser for cooling of several other components. The energy source (26) is arranged to provide electrical energy for operating electric drive (21). The energy source is coupled to the cooling medium circuit and the refrigerant circuit, to exchange heat energy between the cooling medium circuit and the refrigerant circuit. Die Erfindung betrifft ein Kühlsystem (1) für ein Kraftfahrzeug, umfassend: - einen Kühlmittelkreis (2) zum Führen eines Kühlmittels mit einer Kühlereinheit zum Abführen von Betriebswärme von einer oder mehreren Komponenten; - einen Kältemittelkreis (3) zum Führen eines Kältemittels mit einem Kondensator zum Kühlen einer oder mehrerer weiterer Komponenten; wobei eine Energiequelle (26) zum Bereitstellen elektrischer Energie, insbesondere zum Betrieb eines Elektroantriebs (21), vorgesehen ist, wobei die Energiequelle (26) so mit dem Kühlmittelkreis (2) und dem Kältemittelkreis (3) gekoppelt ist, dass die Energiequelle (26) sowohl über den Kühlmittelkreis (2) als auch über den Kältemittelkreis (3) Wärmeenergie austauschen kann.
