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…

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.

LTDH connected appliances - eliminating electricity topping of temperature

, , ,
Kraftringen and COWI A/S have produced this report that shortly describes the technology and history of HWC (Heating Water Circuit) appliances, as well as traditional dishwashers that are connected to hot tap water and washing machines with both hot and cold water connections.

COOL DH newsletter #1: September 2018

Welcome to COOL DH newsletter #1 With close to one year into the COOL DH project we are now ready to launch our first newsletter. Here you will find a mix of the status on each demo site, reports on the different deliverables and innovations…

How to optimize cascade couplings for best use of low temperature sources

,
Kraftringen and COWI A/S have worked together on a paper that describes the analysis of energy efficiency in heat pump systems that recover waste heat from low temperature heat sources for District Heating. Martin Gierow, chemical engineer and…
