District heating is one of the main strategies for providing heat supply buildings in cold climate countries. However, large parts current prefabricated pipes these networks are reaching end their technical service life. Replacing a time-consuming procedure and requires huge investments. Predictive Maintenance (PdM) promising strategy to deal with situations optimize prioritize maintenance activities. This paper surveys different PdM approaches considering difficulties implementing PdMs district (DHNs) compared other energy sectors. It demonstrates that methodology unique each DHN according distinctive characteristics, environmental factors, resource type, available data, equipment, factors. To best authors' knowledge, this presents first comprehensive review focused on various aspects developed DHNs, including data analytics, prediction models, integrated technologies facilitate implementation DHNs. A thorough discussion state-of-the-art real-world challenges presented, potential research avenues provided.

Investigation of the Energy Performance of Thermal Energy Sharing for Photovoltaic-Thermal Systems in a Thermal Prosumer Network

Опубликована: Янв. 1, 2024

This study analyzes the potential for energy saving through integration of a photovoltaic and thermal system with heat pump in community setup small-scale network. An empirical was conducted consisting office buildings residential houses to analyze compare performance network hub storage that utilizes surplus produced by photovoltaic-thermal installed house from other conventional electric hot water boiler. The energy-saving proposed compared existing boiler analyzed, it found electricity consumption could be reduced more than 70% per day system. One can also annual DHW load coverage PVT 50.4%. results this suggest systems combined networks pumps effective reducing consumption, not only individual but as way increase efficiency within communities.

Finding new alternatives is a need to develop disruptive solutions that could be applied the decarbonized, sustainable, circular systemic change for energy system transition. In this case, complete approach, sodium as resource, described. Traditionally, has been considered risky element even if it were proposed coolant in many applications, nuclear or solar thermal plants. Such applications have concerned by explosive reaction of alkali Na with water. We analysed alternative profiting such highly exothermic an use. Previously, we experimentally tested utilization propellant, reported Guerrero et al. (2019), what produced correlation between release and consumption excess are now developing boiler fuelled Based on these previous ongoing activities, paper shows proposal process analysis sodium–water heating cooling networks,as one sectors decarbonized system. A tentative configuration design heater, heat exchangers adapt heated water temperatures will presented. present conceptual 13.5 MW district plant ΔT=10°C from 60 70 °C, consuming 1 kg/s Sodium, reaching efficiency 95%, comparable existing boilers.

This study analyzes the potential for energy saving through integration of a photovoltaic-thermal (PVT) system with heat pump (HP) in community small-scale thermal network. An empirical was conducted to analyze and compare performance HP network hub storage that utilizes surplus produced by PVT installed residential house from other buildings an existing electric hot water boiler. The analysis proposed revealed consumption could be reduced more than 70 % compared system. exhibited COP ranging between 4.2 4.7. Throughout experiment, integrated collected average 23.77 kWh daily units. annual domestic load coverage found 50.4 %. These results indicate systems combined networks HPs can effectively reduce individual enhance efficiency within communities.

Retrofitting a Fifth Generation District Heating and Cooling Network for Heating and Cooling in a UK Hospital Campus

Buildings, Год журнала: 2024, Номер 14(8), С. 2442 - 2442

Опубликована: Авг. 7, 2024

There is an increasingly rich literature on the decarbonisation of heat and evolution networks. This paper investigates whether a novel fifth Generation District Heating Cooling Network (5GDHC) could be retrofitted to existing National Health Service (NHS) hospital campus for purpose heating cooling. The building load was simulated input into custom-written script carry out series parametric studies optimise design options. model calibrated against site data available from facilities management. research found that it feasible use 5GDHC consisting large single mass water utilise inter-seasonal thermal storage. A natural resource such as aquifer not required. tested sizing options larger storage, pumps chillers reduce operating costs improve flexibility. closes with discussion practical factors in retrofitting networks densely occupied highly constrained environment. findings are further describing circumstances which suitable.
