Prototype for new multimedia pipe types for LTDH distribution system

This deliverable investigates the possibility of implementing a heat recovery system in the distribution pipes of a district heating network. The aim with the multimedia pipes is to minimise the heat losses from the distribution pipes.

Draft design manual for new pipe components for LTDH distribution systems underground

,
The implementation of LTDH network and the development of the DH pipes production allow the use of in flexible plastic pipes also for main lines. This deliverable provides the draft of the installation manual of the new pipe components for LTDH distribution systems in Høje-Taastrup and Lund.

Calculator on savings for new high-efficient pipe types for internal distribution in buildings

Improved use of individual metering concepts

, ,
In COOL DH we have studied how to improve individual metering concepts and ways of using gathered data for billing district heating. In the report Improved use of individual metering concepts, we provide an overview of regulations on district heating metering and billing in Sweden and Denmark and an overview on applications to use on customer’s meter readings for energy efficiency improvements.

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.

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

, ,
Kraftringen is building a unique low temperature district heating network. We invite external partners to demonstrate various innovative products and practises in this grid. The test bed is under development, but we are open for ideas from…
