Abstract
A high-temperature circuit through which a high-temperature heat carrier fluid runs and which integrates a cooling radiator in which a cooling fluid flows, and a low-temperature circuit through which a low-temperature heat carrier fluid runs and which integrates a cooling radiator in which the cooling fluid flows, is disclosed. The pumps of the high- and low-temperature circuit form first actuators for running the heat carrier fluid though the circuits and second actuators for flowing the cooling fluids in the high- and low-temperature radiators, and sensors for detecting representative parameters of the cooling requirements of the high- and low-temperature circuits and for transmitting said parameters to a control unit. The transmitted parameters include at least one parameter related to the first actuators and at least one parameter related to the second actuators. The control unit adjusts the first and second actuators according to these parameters.
