Acceptability of sufficiency consumption policies by Finnish households

open access: yesBuildings & Cities
Sufficiency policies aim to decrease and avoid the demand for energy, materials, land and water. This research examines the acceptability of sufficiency consumption policies among Finnish households and how Finnish households experience sufficiency as a ...

Incorporating the Variability of Wind Power with Electric Heat Pumps

open access: yesEnergies, 2011
With the mass introduction of wind power in Northern China, wind power variability has appeared. In this article, both existing electric heat pumps (EHPs) and coal-fired combined heat and power (CHP) facilities, which are generally equipped with ...

Long-Term Performance Measurement and Analysis of a Small-Scale Ground Source Heat Pump System

open access: yesEnergies, 2020
Recent data suggest that heat pumps, despite having the potential to cover over 90% of the global space and water heating demands, only provide less than 5% of global heating.

Density waves in the shearing sheet III. Disc heating [PDF]

open access: yes, 2001
The problem of dynamical heating of galactic discs by spiral density waves is discussed using the shearing sheet model. The secular evolution of the disc is described quantitatively by a diffusion equation for the distribution function of stars in the ...

Geothermal space heating [PDF]

open access: yesGeothermics, 2003
The use of geothermal resources for space heating dominates the direct use industry, with approximately 37% of all direct use development. Of this, 75% is provided by district heating systems. In fact, the earliest known commercial use of geothermal energy was in Chaudes-Aigues Cantal, France, where a district heating system was built in the 14th ...

CO2 refrigeration system heat recovery and thermal storage modelling for space heating provision in supermarkets: An integrated approach

open access: yesApplied Energy, 2020
The large amount of recoverable heat from CO2 refrigeration systems has led UK food retailers to examine the prospect of using refrigeration integrated heating and cooling systems to provide both the space heating and cooling to food cabinets in ...

Regimes of heating and dynamical response in driven many-body localized systems [PDF]

open access: yes, 2016
We explore the response of many-body localized (MBL) systems to periodic driving of arbitrary amplitude, focusing on the rate at which they exchange energy with the drive. To this end, we introduce an infinite-temperature generalization of the effective "

Heat Kernel and Moduli Space [PDF]

open access: yesMathematical Research Letters, 1996
The author describes a proof of the formulas of \textit{E. Witten} [Commun. Math. Phys. 141, No. 1, 153-209 (1991; Zbl 0762.53063); J. Geom. Phys. 9, No. 4, 303-368 (1992; Zbl 0768.53042)] about the symplectic volumes and the intersection numbers of the moduli spaces of principal bundles on a compact Riemann surface.

Applying Solar PV to Heat Pump and Storage Technologies in Australian Houses

open access: yesEnergies, 2021
Innovative mechanical services coupled with renewable energy systems are crucial for achieving a net zero energy goal for houses. Conventional systems tend to be vastly oversized because they lack the means to buffer energy flows and are based on peak ...

Diagnosing the time-dependence of active region core heating from the emission measure: II. Nanoflare trains [PDF]

open access: yes, 2013
The time-dependence of heating in solar active regions can be studied by analyzing the slope of the emission measure distribution cool-ward of the peak.
