The COOL DH-project is now closing its innovation process phase, which focused on different installation solutions for consumers, the distribution side and the production side.
In this report you will learn about the design process of a low-temperature district heating network, highlighting the design factors that lead to reduction of heat losses in the distribution pipes. To demonstrate the technology, two real-scale demonstration projects are described in Høje-Taastrup, Denmark and in Lund, Sweden. Emanuele Zilio, engineer at COWI A/S, gave a short interview to summarize the report
This deliverable summarizes and gives an overview of existing and newly developed technical solutions used for the domestic hot water production that can be implemented in low temperature or ultra-low temperature district heating networks, and that can increase the share of renewable energy in the building sector.
Kraftringen is building a unique low temperature district heating network. We invite external partners to demonstrate various innovative products and practises in this grid. The test bed is under development, but we are open for ideas from external participants. Some of the current ideas regard: Production: Software for heat storage purposes, optimisation of the production […]
The future City Hall in Høje-Taastrup will kick-start the development of the new district Høje-Taastrup C. The City Hall will be heated with low temperature district heating based on solutions developed in the COOL DH project
The pipe heat losses in the circulation of domestic hot water (DHW) can be high in comparison to the demand and use of DHW. Flat stations can be used in order to potentially lower these heat losses. Kraftringen, COWI A/S and Cetetherm have looked closer on solutions with flat stations in buildings with low district […]
On the Innovation webinar we presented some of the main findings from COOL DH first year with focus on innovations for low temperature district heating.
Høje Taastrup District Heating and COWI A/S have examined the potential of a short time and seasonal energy storage in the municipality of Høje-Taastrup. The storage will be established as an ATES plant. Uffe Shleiss from Høje Taastrup District Heating summarizes the findings. What is the main purpose of the deliverable? The deliverable has the […]
A little more than one year into the project, we have now gotten far in the innovation process on developing smart city LTDH-solutions and system optimization with interesting results. In this webinar, we will present some of these findings.
