Circuit arrangement for cooling charge air and method for operating a circuit arrangement of this type

The invention relates to a circuit arrangement (K) comprising a low-temperature circuit (NK) for cooling charge air that is fed to a motor in a motor vehicle equipped with a turbocharger. According to the invention, the charge air is compressed in two stages in a first low-pressure turbocharger and a second high-pressure turbocharger. To cool the charge air a first cooler is provided downstream of the low-pressure turbocharger and upstream of the high-pressure turbocharger and a second cooler is provided downstream of the high-pressure turbocharger and upstream of the motor. The invention also relates to a method for operating a circuit arrangement (K) of this type.
