In the COOL DH-project we will demonstrate how new solutions within low temperature district heating are tested and installed at the demo sites in Lund and Høje-Taastrup. On this page you will find information and public reports regarding the demonstrations.
New type of substations to meet the requirements of LTDH
The transition to low-temperature supply in district heating networks requires new technical solutions to meet the heat requirements of the consumers and guarantee their safety. The new distribution system at the COOL DH demo site in Høje-Taastrup does just that!
Converting Østerby area from traditional DH (85/50°C) to LTDH
The report provides information about the final design and the implementation of the low-temperature district heating network. It can be used as a guideline of the installation process and the challenges found during the installation process and a reference for future similar projects.
Local energy solution with heat pump hot water topping
Xplorion is a 3300 m2 passive house with 54 apartments and a café / restaurant at the corner. Kraftringen has demonstrated a supply and user installation of ultra low temperature 5th generation district heating in the Xplorion-building.
Innovative three pipe solutions
The circulation of warm water to produce hot tap water is a bad solution for both house owners and energy companies as it results in increased energy consumption and an increased return temperature. Even though Xplorion is already an environmental friendly building, Kraftringen has demonstrated a solution to reduce energy consumption even further.
