Energy flexibility and District Heating Control

The activities carried out under the RELaTED project address the need for increased energy efficiency and new management strategies in relation to ULT DH. Installing smart meters allows for increased insight into the conditions of networks and installations and by the use of machine learning to utilize these data in new algorithms and tools. RELaTED report 2.4, which is part of a set of reports that define the system architecture of the RELaTED concept, describes new possibilities concerning measurement and control of ULT DH and other DH systems with high energy flexibility. RELaTED task 2.4 aims at developing a framework for advanced control procedures for managing and optimizing ULT DH networks based on energy consumers equipped with smart meters and [...]

Development schemes for new district heating developments

How can low temperature concepts be applied in new urban developments? The RELaTED Task 2.5 describes a set of guidelines that are, in general terms, based on best practices as most new urban development areas are different in relation to visions, DH network topology, temperature levels, buildings installations, tariff structure, management etc. […]

Prevention of legionella: actions to find safe domestic hot water solutions in relation to district heating

Use of low and ultra-low DH temperatures, that proposes RELaTED project, results in an increase of the energy efficiency of the heating system. However, the low temperatures in general also increase the risk of Legionella. This emphasizes the need of finding safe Legionella solutions for the domestic hot water (DHW) production from district heating (DH). Focus has been on both large installations in multi-family houses and commercial buildings often using a storage tank for hot water, and for smaller installations in one-family houses or in each flat in newer multi-storey houses with instantaneous heating by a heat exchanger. A survey of various challenges and solutions can be found in the IEA Guidebook “Future Low Temperature District Heating Design Guidebook” from [...]

Definitions of ultra-low temperature district heating

District heating companies, equipment manufacturers, consultants and researchers have discussed definitions of district heating and cooling in general, and also ultra-low temperature district heating. This inform explains the different definitions and most used terms to give the reader not familiar with district heating the background of this system and the technology options. DOWNLOAD THIS DOCUMENT >> Photo by Pixabay from Pexels In the report "Benchmark for performance levels" (C. H. Christiansen, N. Winther, Ecoheat Cities WP2-report, 2012), the following indicative temperature levels and definitions were specified: DH High Temperature System (HT), 100/50 °C DH Low Temperature System (LT), 80/40 °C DH Very Low Temperature System (VLT), 60/30 °C DH Ultra Low Temperature System (ULT), 45/30 °C District cooling [...]

VIDEO: Aventa develops an innovative solar collector system for district heating

Michaela Meir, R&D manager from Aventa and leader of work package 3 in RELaTED project, explains at this video the solution that this Norwegian company is developing in this project. Both the Spanish company IMAR and Aventa are developing solar collector systems for heating. Aventa’s innovation in RELaTED is that these collector systems are decentralized at the end-user side using the district heating network as storage. The final aim is to install the developed technologies at the RELaTED demo sites. Aventa has developed and produced an all-polymeric solar collector of modular design and flexible in dimensions for building integration. Aventa has pioneer in the delivery of solar thermal collectors fully constructed in polymeric structured sheets. Due to mass production processes [...]

Video: District heating solutions by RELaTED project and METRO THERM

In this video, Kasper Korsholm Østergaard, PhD, R&D Manager at METRO THERM A/S explains some details of their contribution to the RELaTED project ultra low temperature district heating concept. METRO THERM is a Danish-based company with a long tradition in the production of district heating units and heat pumps. METRO THERM is also one of the 14-companies which have coordinated their interests, technologies and investment roadmaps to develop, deploy and test the RELaTED project concept. The most relevant part of the RELaTED project for METRO THERM is the development of a triple function substation and the use of a microbooster heat pump in ultra low temperature district heating.
