Welcome to COOL DH newsletter #2

, , ,
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.

New design concepts for optimisation of LTDH distribution systems

, , , , ,
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

Solutions for local integration of renewable energy sources (RES)

, ,
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.

Invitation to external partners to be part of a test bed for Low Temperature District Heating

, ,
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…

The future City Hall in Høje-Taastrup to be heated with solutions from COOL DH

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

System solutions for multifamily houses and tertiary buildings

, , ,
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…

Watch the recorded Innovation webinar

, , , ,
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.

Development of short time and seasonal energy storage

, ,
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…

Welcome to COOL DH Innovation Webinar 12th December

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.

Solutions for avoiding risk of Legionella

Low temperatures in domestic hot water systems increases the risk of growth of Legionella bacteria which if inhaled can cause Pontiac fever or Legionnaires' disease. Lund University, Kraftringen and COWI have worked on a report that investigates solutions for avoiding risk of Legionella when using LTDH. Kerstin Sernhed from Lund University (Dept. of Energy Sciences) introduces the report.
