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 closer on solutions with flat stations in buildings with low district Read more about System solutions for multifamily houses and tertiary buildings[…]

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 Heating summarizes the findings. What is the main purpose of the deliverable? The deliverable has the Read more about Development of short time and seasonal energy storage[…]

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.

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 project manager at Kraftringen, introduces the report that you can download below. What is the main purpose Read more about How to optimize cascade couplings for best use of low temperature sources[…]

COOL DH at the Nordic Clean Energy Week

Sara Kralmark and Göran Strandberg from Kraftringen together with Mårten Ahlm from Alfa Laval held a presentation on COOL DH at the Nordic Clean Energy Week. With an audience of about 130 people, the presentation created a lot of interest in the COOL DH project. Kraftringen and Alfa Laval took the opportunity to present COOL Read more about COOL DH at the Nordic Clean Energy Week[…]
