    • In a method for operating a cooling and heating circuit of a motor vehicle driven by an internal combustion engine, a first cooling medium path is provided through a bypass conduit, a second cooling medium path is provided through a main cooler of the internal combustion engine, a third cooling medium is provided through a heating heat exchanger, and a fourth cooling medium path is provided through a heat accumulator. The cooling medium flows through the paths are subdivided by an electrically operated valves, and the cooling medium flows are generated by at least one pump. The valves are controlled by a control unit based on operational and environmental parameters as well as nominal values, and a third control valve which is controlled by the control unit is arranged in the fourth cooling medium path. The circuit is operated so that the third control valve is closed completely or partially when a reference temperature of a remaining cooling and heating circuit exceeds a nominal value provided in the control unit, and the third control valve is opened when the reference temperature is below the nominal value.
    • 在一种用于操作由内燃机驱动的机动车辆的冷却和加热回路的方法中,通过旁通管道提供第一冷却介质路径,通过内燃机的主冷却器提供第二冷却介质路径, 通过加热热交换器提供第三冷却介质,并且通过蓄热器提供第四冷却介质路径。 流经路径的冷却介质被电动阀细分,冷却介质流由至少一个泵产生。 所述阀由控制单元基于操作和环境参数以及标称值控制,并且由所述控制单元控制的第三控制阀布置在所述第四冷却介质路径中。 操作电路,使得当剩余冷却和加热回路的参考温度超过设置在控制单元中的标称值时,第三控制阀完全或部分关闭,并且当参考温度低于控制单元时,第三控制阀打开 面值。
