Incorporating a distributed, local waste heat source into the LTDH grid

, ,
As the temperature in the DH grids generally, and LTDH grids specifically, is gradually lowered it allows for new types of production to be included in the grid. The value of waste heat from “prosumers” has been considered too low in terms of temperature and volume, but that is no longer the case.

Producing heating, cooling and surplus heating for the LTDH grid

, ,
In COOL DH we develop and demonstrate a range of technologies to supply low-temperature networks with heat without compromising the users' comfort and the efficiency of the district heating system. In Lund, Kraftringen has installed a heat recovery system at MAX IV research facility, supplying the new Brunnshög district with low temperature district heating.
