District Heating and Cooling Networks [PDF]
, 2020 Conventional thermal power generating plants reject a large amount of energy every year. If this rejected heat were to be used through district heating networks, given prior energy valorisation, there would be a noticeable decrease in the amount of fossil fuels imported for heating.

District Heating and Cooling Systems
Fuel and Energy Abstracts, 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 ...

District Power-To-Heat/Cool Complemented by Sewage Heat Recovery [PDF]
Energies, 2019 District heating and cooling (DHC), when combined with waste or renewable energy sources, is an environmentally sound alternative to individual heating and cooling systems in buildings. In this work, the theoretical energy and economic performances of a DHC network complemented by compression heat pump and sewage heat exchanger are assessed through ...

Optimization of Solar District Heating & Cooling Systems
Journal 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.

Mapping of Turkey’s District Heating/Cooling Requirements
Politeknik Dergisi, 2020 One of the most important parameters of energy efficiency is to determine the heating and cooling requirements of the buildings and to develop the appropriate heating/cooling technology. In this study, the regional residence heating/cooling loads were determined in order to develop technology for regional heating/cooling systems in Turkey.
