A cooling system for a motor vehicle has an electrical energy storage device for driving the motor vehicle; a chiller through which a refrigeration circuit and, fluidically separated therefrom, a main cooling circuit can flow; one or more control elements; at least one heat source, and one or more ambient air coolers. In a first mode, the control elements form the main cooling circuit such that the main cooling circuit can flow through the chiller, the energy storage device and none of the ambient air coolers. In a second mode, the control elements form the main cooling circuit such that the main cooling circuit can flow through the chiller, the energy storage device and at least one of the ambient air coolers. In a third mode, the control elements form the main cooling circuit such that the main cooling circuit can flow through the chiller, at least one of the ambient air coolers and the heat source.

Cooling system for a motor vehicle and motor vehicle having such a cooling system

A heating system for an electric or hybrid vehicle, to which a high-voltage accumulator is connected, includes a coolant circuit having a heating circuit to which a heating heat exchanger is connected for air-conditioning the interior, and having a cooling circuit to which a cooler and a heat source are connected. The heating system has at least two refrigerating circuits, wherein a first refrigerating circuit includes an air-conditioning evaporator for air-conditioning the interior, and a first condenser, by which the first refrigerating circuit is thermally coupled to the coolant circuit in order to dissipate heat from the first refrigerating circuit. The second refrigerating circuit is thermally coupled by a second condenser to the coolant circuit. The two refrigerating circuits, however, are not coupled to each other. At least one of the refrigerating circuits further includes a chiller in order to dissipate heat from the coolant circuit.
