Abstract

A cooling system for a supercharged internal combustion engine may include a charge air cooling circuit, in which a low-temperature coolant circulates and which may have a low-temperature charge air cooler for cooling charge air and a low-temperature coolant cooler for cooling the low-temperature coolant. The system may include a refrigerant circuit, in which a refrigerant circulates and which has a vaporizer for vaporizing the refrigerant and a condenser for condensing the refrigerant. The system may include a coupling heat exchanger for a fluidically separated, heat-transmitting coupling of the charge air cooling circuit with the refrigerant circuit. The coupling heat exchanger may be arranged in a vaporizer bypass of the refrigerant circuit thereby bypassing the vaporizer and be arranged in a coupling branch of the charge air cooling circuit. The coupling branch may branch off via a branching-off point from a feed of the charge air cooling circuit.
