The purpose with this review is to provide a presentation of the background for current position district heating and cooling in world, some deeper insights into European conditions. structure considers market, technical, supply, environmental, institutional, future contexts. main global conclusions are low utilisation buildings, varying implementation rates respect countries, moderate commitment fundamental idea heating, recognition possible carbon dioxide emission reductions, awareness...
Using a neutron interferometer of the type first developed by Bonse and Hart for x rays, we have observed effect Earth's rotation on phase wave function. This experiment is quantum mechanical analog optical interferometry observations Michelson, Gale, Pearson.
The purpose with this review is to provide a presentation of the background and current position for district heating cooling in Sweden. structure considers market, technical, supply, environmental, institutional, future contexts. main conclusions are high utilisation Swedish buildings, commitment third generation technology, proportions heat recycling renewable compliance European definition efficient heating, considerable reductions fossil carbon dioxide emissions, strong national driving...
Fourth-generation district heating (4GDH) has been used as a label or expression since 2008 to describe transition path for decarbonization of the sector and was defined in more detail 2014. During recent years, several papers have published on concept called fifth generation cooling (5GDHC). This article identifies differences similarities between 4GDH 5GDHC regarding aims abilities. The analysis shows that these two are common not only overarching aim but they also some extent share five...
The Heat Roadmap Europe (HRE) studies estimated a potential increase of the district heating (DH) share to 50% entire heat demand by 2050, with approximately 25–30% it being supplied using large-scale electric pumps. This study builds on this and aims document that such developments can begin now technologies currently available. We present database status technology its ability expansion other European locations reviewing experiences aimed at further research or application in industry. is...
Power-to-heat solutions like heat pumps and electric boilers are foreseen to be possible future tools stabilise international power markets with high proportions of variable supply. Temporary low cost electricity can used for generation at times availability wind solar through substitution ordinary supply, hence contributing increased energy system sustainability. installations in district heating systems competitive due specific investment installation costs large boilers, pumps, storages....
The experiments described in this paper probe the simultaneous effects of gravity, inertia, and quantum mechanics on motion neutron. Using a neutron interferometer type developed by Bonse Hart for x rays, we have observed quantum-mechanical interference phenomena induced gravitational field Earth Earth's rotation relative to fixed stars. importance these with regard role principle equivalence is discussed.
District heating systems contribute with low primary energy supply in the system by providing heat from assets like combined and power, waste incineration, geothermal heat, wood waste, industrial excess heat. These would otherwise be wasted or not used. Still, there are several reasons to use these as efficiently possible, i.e., ability compete, further reduced of resources, less environmental impact. Low return temperatures distribution networks important operational factors for obtaining...
Heat load variations in district heating systems are both seasonal and daily. Seasonal have mainly its origin from outdoor temperature over the year. The of daily is induced by social patterns due to customer behaviours. cause increased costs because peak heat capacity expensive fuels. well-documented analysed, but analyses scarce. Published either case studies or models that try predict variations. There a dearth suitable assessment methods for more general existing In this paper, novel...
District heating satisfies about 60% of the heat demand in Swedish buildings. Today, more than two thirds supply to district systems is based on biomass and waste, alone accounts for half supply. The purpose this paper present experiences introducing expanding use identify main drivers behind development. Our five research questions corresponding conclusions consider driving forces from energy policy tools local initiatives, prices, established infrastructures forestry heating, technology...
Current temperature levels in European district heating networks are still too high with respect to future conditions as customer heat demands decrease and new possible source options emerge. A considerable reduction of can be accomplished by eliminating current faults substations systems. These do not receive proper attention today, because neither nor systems centrally supervised. The focus this paper has been identify these annual series hourly meter readings obtained from automatic...
Future smart energy grids will require more information exchange between interfaces in the system. One interface where dearth of exists is district heating substations, being distribution network and customer building systems. Previously, manual meter readings were collected once or a few times year. Today, automatic are available resulting low cost hourly reading data. In system, errors deviations substations propagates through to heat supply plants. order reduce future supplier costs,...
The main impetus for lower distribution temperatures in district heating systems is the heat supply costs obtained by these temperatures. In this paper, differences two different temperature levels have been estimated various future options. estimations were modelling a system characterised typical climate conditions Central Europe. High sensitivity to from was found geothermal heat, industrial excess and pumps, whereas low cost combined power plants using waste or biomass. Lower loss...
