LTDH-heated benches installed in Lund

,
Kraftringen are opening up to make the LTDH-grid in Brunnshög a testbed for creative solutions, as well as promoting good cooperation of parties active in the DH sector. One example are the newly installed, artistic LTDH-heated benches at Möllegården.

Heat-recovery enabled pipes

,
In classic district heating grids, up to 15-20 % of all the energy produced does not reach the customers due to heat losses. This is a weakness with district heating which we are addressing in COOL DH.
The future of thermal grids

Join us at The Future of Thermal Grids

Heat pumps installed in MAX IV

Producing heating, cooling and surplus heating for the LTDH grid

, ,
In COOL DH we develop and demonstrate a range of technologies to supply low-temperature networks with heat without compromising the users' comfort and the efficiency of the district heating system. In Lund, Kraftringen has installed a heat recovery system at MAX IV research facility, supplying the new Brunnshög district with low temperature district heating.

New design concepts for optimisation of LTDH distribution systems

, , , , ,
In this report you will learn about the design process of a low-temperature district heating network, highlighting the design factors that lead to reduction of heat losses in the distribution pipes. To demonstrate the technology, two real-scale demonstration projects are described in Høje-Taastrup, Denmark and in Lund, Sweden. Emanuele Zilio, engineer at COWI A/S, gave a short interview to summarize the report

Solutions for local integration of renewable energy sources (RES)

, ,
This deliverable summarizes and gives an overview of existing and newly developed technical solutions used for the domestic hot water production that can be implemented in low temperature or ultra-low temperature district heating networks, and that can increase the share of renewable energy in the building sector.
