About the project
Renewable Low Temperature District, RELaTED, will provide an innovative ultra-low temperature concept for thermal district energy networks with lower cots, fewer heat losses, better energy performance and more extensive use of de-carbonized energy sources than actual district heating concept.
The main objective of RELaTED Ultra-Low Temperature District Heating is to demonstrate the feasibility of the concept, with large share of renewable energy and waste heat sources, in European urban environments, and its suitability for the upcoming operational environment with reduced heat loads and distributed heat sources.
To prove this, RELaTED will be demonstrated in four real demonstrations sites (Denmark, Estonia, Serbia and Spain), with two additional feasibility studies.
The low temperature concept will be implemented by means of adaptation of commonly available district heating network components.
However, some technologies must be adapted to the particularities of the system. Network substations, heat pumps and building integrated solar thermal systems will be adapted to the new operational environment.
The RELaTED project partners Metro Therm and DTI presented a novel microbooster heat pump at the 4th International Conference on Smart Energy Systems and 4th Generarion District Heating, that took place in Aalborg (Denmark). Read [...]
