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.

Corona, webinars, CPS and new substations: COOL DH newsletter #4

, , , ,
It has been a strange spring. Each person around the globe has felt the effects of the spread Covid-19, but so far it has had a relatively limited impact on the overall progress of the COOL DH-project. There has been some problems with deliveries…
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!
