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

Invitation to external partners to be part of a test bed for Low Temperature District Heating
