LTDH-heated benches installed in Lund

,
Kraftringen are opening up to make the LTDH-grid in Brunnshög a testbed for creative solutions, as well as promoting good cooperation of parties active in the DH sector. One example are the newly installed, artistic LTDH-heated benches at Möllegården.

Connection of Prosumers in Høje Taastrup

,
The transition to low-temperature supply in district heating networks as well as the transition towards renewable heat sources require new technical solutions that allow the introduction of new actors in the district heating sector. These new actors are defined as prosumers that are both connected to the district heating network as consumers and can deliver heat to the network. In Høje-Taastrup Municipality, different prosumers are already connected or in the process to be connected to the district heating and cooling network.

A smart energy system coming to place in Høje-Taastrup

, ,
In this video you will see how low-temperature district heating and large heat pumps are an essential element in Høje Taastrup District Heating and Høje-Taastrup Municipality's collaborative journey towards an efficient, flexible and smart energy system.

New type of PE-RT pipes with leakage detection

The possibility to detect potential leakage in a DH (or LTDH) system is crucial. In COOL DH, plastic media pipes are used instead of the classic steel media pipes. This requires a slightly different solution to detect leakage.

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.

Heat-recovery enabled pipes

,
In classic district heating grids, up to 15-20 % of all the energy produced does not reach the customers due to heat losses. This is a weakness with district heating which we are addressing in COOL DH.

Design Guide for Low Temperature District Heating

,
This guide by Cetetherm explains how to design and prepare buildings to be able to integrate low temperature district heating. It will assess the best of hot water and space heating system design for different buildings categories.

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.

Xplorion – a pioneering multi family building with climate friendly solutions

,
Xplorion in Lund is a world-class innovation project for those who want to live sustainable. The building focuses on climate-smart solutions that are highly present in the tenant’s everyday life. Two solutions within COOL DH are demonstrated in Xplorion: Local energy solution with heat pump hot water topping and an innovative three-pipe solution.
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.
