COOL DH: Cool ways of using low grade Heat Sources for District Heating

  • Our Projects
  • October 2017 to September 2021

Cool ways of using low grade Heat Sources from Cooling and Surplus Heat for heating of Energy Efficient Buildings with new Low Temperature District Heating (LTDH) Solutions.

Description/Objectives:

COOL DH focuses on technology innovation – such as exploiting low grade energy sources and new energy efficient energy distribution pipes – and user installations for low temperature district heating combined with integration of local renewable energy sources.

COOL DH will:

  • Innovate, design and build cooling and heat recovery process systems, enabling heat recovery to a local low temperature district heating grid.
  • Design and build a low-temperature district heating grid with non-conventional pipe materials and testing of new innovative pipe components.
  • Innovate and design suitable innovative heating systems and controls inside buildings that combine LTDH with distributed integration of local produced renewable energy on the buildings.
  • Develop viable business models and new pricing systems, that ensures a good (low) return temperature and provide the building companies with maximum flexibility regarding the choice of heating systems.
  • Demonstrate a full system with all needed components suitable for ultra-low DH temperatures (40 oC) including demonstration of systems for heating of DHW without risk of legionella.

Partners:

The COOL DH consortium consists of the utilities and municipalities of the two cities Lund (SE) and Høje-Taastrup (DK) and leading DH energy specialists as well as leading industrial manufacturers:

COWI A/S (Denmark), Kraftringen Energi AB (Sweden), Høje-Taastrup Kommune (Denmark), Lunds Kommun (Sweden), Lund University (Sweden), Euroheat & Power (Belgium), Logstor A/S (Denmark), Høje Taastrup Fjernverme amba (Denmark), COWI AB (Sweden), Alfa Laval AB (Sweden), Lunds Kommuns Fastighets AB (Sweden)
