| 摘要 |
The invention relates to a method for the transport of heat energy from at least one heat source to at least one heat sink, in particular for a district heating network, by means of a working fluid which includes a mixture of at least one first component having a first boiling point and of a second component having a second boiling point, with the first boiling point being lower than the second boiling point. The method includes the step of an at least partial vaporization of the first component of the working fluid by the supply of heat from the heat source. The vaporized portion of the first component is transported separately from the working fluid depleted by the vaporization with respect to the first component from the heat source to the heat sink by means of a transport means. Subsequently, the vaporized first component is absorbed by the depleted working fluid while emitting the heat absorbed on the vaporization to the heat sink. The temperature of the first component and of the depleted working fluid on the transport from the heat source to the heat sink substantially corresponds to a temperature prevailing in the environment of the transport means. The invention further relates to an extraction apparatus to increase the efficiency of the extraction of a component of the working fluid and to a district heating network for the transport of heat energy.
