The use of radiator shutters is also advantageous for improving the aerodynamics and thus to reduce fuel consumption.
  • the cooling performance of the coolant radiator is deteriorated because there is no longer enough wind to cool the coolant flowing through the coolant radiator. Therefore, in this case too, an additional cold water storage for cooling the engine block, which is achieved by the use of the storage device or its integration into the third refrigerant circuit, is particularly advantageous. Due to the configuration according to the invention, an extended transit time in shutter operation can advantageously be realized.

  • the output of the storage device is connected to the engine block via the third cooling circuit.
  • the output of the storage device is connected to an inlet of a second valve.
  • the second valve has a first outlet and a second outlet.
  • the first outlet of the second valve directs the coolant into the third cooling circuit to the engine block, and the second outlet of the second valve directs the coolant into the second coolant loop to the heater.
  • the coolant coming from the storage device via the third coolant circuit can be fed into the engine block via a pump suction side when the storage device acts as a kite pesher.
  • a second heat exchanger in particular a low-temperature cooler, is provided in the circuit arrangement.
  • the storage device is charged with cold coolant coming from the low-temperature cooler, the high-temperature coolant cooler cooling the engine block via the first coolant circuit.
