RELaTED Project: New Developments on Ultra-Low Temperature District Heating Networks

open access: yesProceedings, 2020
District 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

Investigation on Relative Heat Losses and Gains of Heating and Cooling Networks

open access: yesEnvironmental and Climate Technologies, 2021
The integration of district heating (DH) and cooling (DC) in the sustainable energy system of the future requires a significant reduction in operating temperatures. Supply temperatures below 70 °C are required for new 4th Generation DH. Main benefits are

Optimization of Solar District Heating & Cooling Systems

open access: yesJournal of Physics: Conference Series, 2022
Abstract The present work proposes a comparison between three solar-powered district heating and cooling systems, namely: 1) centralized district heating & cooling (DHC) system; 2) 5th-generation district heating & cooling (5GDHC) system and 3) individual AC plants (HHC, Home Heating and Cooling), in different climate conditions.

District Heating and Cooling Systems

open access: yes, 2021
Decarbonisation of the energy sector is a crucial ambition towards meeting net-zero targets and achieving climate change mitigation. Heating and cooling accounts for over a third of UK greenhouse emissions and, thus, decarbonisation of this sector has attracted significant attention from a range of stakeholders, including energy system operators ...
