Abstract:
1. A circuit arrangement, comprising: a low temperature coolant circuit configured to cool charge air in a motor vehicle having a supercharger, a main coolant circuit in addition to the low temperature coolant circuit, wherein the main coolant circuit is configured to provide coolant to an engine, wherein the main coolant circuit and the low temperature coolant circuit are connected so that there is an exchange of coolant between the main coolant circuit and the low temperature coolant circuit, a single-unit, integrated charge-air and coolant radiator, wherein the low temperature coolant circuit comprises a coolant passage configured to cool the single-unit, integrated charge-air and coolant radiator with coolant flowing through the passage, and a temperature sensor provided at a coolant outlet of the radiator, wherein the temperature sensor is located at the coolant outlet prior to any branches in a coolant passage extending from the coolant outlet, wherein the temperature sensor is configured to measure a coolant outlet temperature.
