Abstract
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.
