Item Lessons Learnt from Substation Inspection on Low Temperature District Heating Networks(2021-12-24) Garrido-Marijuan, Antonio; Eguiarte, Olaia; Garay-Martinez, Roberto; Raud, Margus; Hagu, Indrek; Tecnalia Research & InnovationDistrict heating networks are considered to be a key element for the decarbonization of Europe. The RELaTED project seeks to contribute to the decarbonization of these infrastructures with the demonstration of low temperature district heating networks. One of the demonstration sites consists of more than 50 substations within a subsection of a larger network in the city of Tartu (Estonia), where the temperature was lowered by 10 ◦C. To ensure the benefits of this new generation district heating network and the fulfillment of comfort requirements, data have been monitored and analyzed at the substation level in an automatic way to facilitate the inspection of every user.Item RELaTED Project: New Developments on Ultra-Low Temperature District Heating Networks(Multidisciplinary Digital Publishing Institute (MDPI), 2020-12-25) Marijuan, Antonio Garrido; Garay, Roberto; Lumbreras, Mikel; Sánchez, Víctor; Macias, Olga; Rozas, Juan Perez Sainz DeDistrict heating networks deliver around 13% of the heating energy in the EU, being considered as a key element of the progressive decarbonization of Europe. The H2020 REnewable Low TEmperature District project (RELaTED) seeks to contribute to the energy decarbonization of these infrastructures through the development and demonstration of the following concepts: reduction in network temperature down to 50 °C, integration of renewable energies and waste heat sources with a novel substation concept, and improvement on building-integrated solar thermal systems. The coupling of renewable thermal sources with ultra-low temperature district heating (DH) allows for a bidirectional energy flow, using the DH as both thermal storage in periods of production surplus and a back-up heating source during consumption peaks. The ultra-low temperature enables the integration of a wide range of energy sources such as waste heat from industry. Furthermore, RELaTED also develops concepts concerning district heating-connected reversible heat pump systems that allow to reach adequate thermal levels for domestic hot water as well as the use of the network for district cooling with high performance. These developments will be demonstrated in four locations: Estonia, Serbia, Denmark, and Spain.
