Abstract

The invention relates to a heat exchange medium circuit with at least one heat exchange medium transport circuit (11) for transporting heat exchange medium and at least one heat exchange medium overflow circuit (12) for exchanging heat exchange medium with the heat exchange medium transport circuit. The heat exchange medium overflow circuit has at least one overflow vessel (121) which can be activated depending on an activation value of at least one operating parameter of the heat exchange medium circuit, with the result that the overflow vessel is available for the exchange of heat exchange medium between the heat exchange medium overflow circuit and the heat exchange medium transport circuit. A method for transporting heat exchange medium with the aid of the heat exchange medium circuit is likewise specified, wherein the overflow vessel is activated depending on the activation value of the operating parameter, with the result that the exchange of heat exchange medium between the heat exchange medium overflow circuit and the heat exchange medium transport circuit takes place with the aid of the overflow vessel. When the activation value of the operating parameter is reached, the overflow vessel is coupled to the heat exchange medium overflow circuit. The heat exchange medium is preferably a heat transfer oil. The heat exchange medium circuit is used in a solar heat power plant for producing electric power.
