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.

PV powered cascade heat pump installed in the Østerby district

, ,
In Høje-Taastrup municipality a new heat pump system at the shopping mall CITY2 has been installed. The system supplies the new low-temperature district heating network in Østerby district demo case, including business and nearby hotels, recovering the waste heat from the cooling system.

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 innovative main line with heat recovery

,
On the demonstration site in Høje-Taastrup municipality a new type of multimedia pipe system with heat recovery has been installed in the distribution network. The product developed shows that it is possible to integrate collector pipes in standard district heating pipes to recover heat and minimise heat loss.

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.
