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.
Virtual study tour Brunnshög

A VIRTUAL STUDY TOUR TO THE WORLD’S LARGEST LTDH-GRID

,
Since the pandemic prevents us from welcoming visitors and arrange study tours, we decided to arrange a virtual study tour to Brunnshög that you can join whenever you like.
The image shows how the installation of the LTDH-service pipes in Osterby are close to the users' buildings in order to reduce the length of the network and consequently the heat losses.

From traditional DH to LTDH in Østerby

, , , ,
A new low-temperature network has been designed to upgrade the old and obsolete traditional district heating-network in Høje-Taastrup. This report provides information about the final design and the implementation of the low-temperature district heating network and can be used as a guideline of the installation process for future similar projects.
New type of substation

New type of substation to meet the requirements of LTDH

, ,
The transition to low-temperature supply in district heating networks requires new technical solutions to meet the heat requirements of the consumers and guarantee their safety. The new distribution system at the COOL DH demo site in Høje-Taastrup does just that!

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.

On Tuesday 24th September the world’s largest low temperature district heating network was inaugurated in Brunnshög, the sustainable future district in the northeast part of Lund, Sweden. Science Village Scandinavia’s conference facility…

Draft design manual for new pipe components for LTDH distribution systems underground

,
The implementation of LTDH network and the development of the DH pipes production allow the use of in flexible plastic pipes also for main lines. This deliverable provides the draft of the installation manual of the new pipe components for LTDH distribution systems in Høje-Taastrup and Lund.
