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.
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.
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.
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.
