Circuit for decreasing the primary return temperature in district heating systems

摘要

The system (1) has a heat pipe system (3) fluid connected with a heat exchanger (8) over a secondary side so that the pipe system is heated by heat from another heat pipe system (2). The former pipe system is fluid separated from the latter pipe system. A pipeline section connects the heat exchanger with another end (12) of the latter pipe system on a primary side in fluid connection manner. The former pipe system includes a heat transfer medium-buffer storage i.e. heat transfer medium tank, for heat transfer medium, which is heated by another heat exchanger (15) in the storage. The heat transfer medium is drinking water. An independent claim is also included for a method for heating a heat transfer medium of a heat pipe system of a pipeline system.
