Ground-source heat pumps and underground thermal energy storage: energy for the future [PDF]

, 2008
We need energy for space heating—but in most cases not where or when energy sources are available. Energy storage, which helps match energy supply and demand, has been practised for centuries, also in Norway.

Analysis of retrofit air source heat pump performance : results from detailed simulations and comparison to field trial data [PDF]

, 2011
In the UK, gas boilers are the predominant energy source for heating in housing, due primarily to the ready availability of natural gas. The take-up of heat pumps has lagged far behind Europe and North America.

Thermal quadrupole method with internal heat sources [PDF]

, 2012
A new method based on the thermal quadrupoles technique for heat transfer modelling in multilayered slabs with heat sources is proposed. Classical thermal quadrupoles use hyperbolic functions and numerical problems occur according to the argument value ...

Prediction of Terrestrial Heat Flow in Songliao Basin Based on Deep Neural Network

Earth and Space Science, 2023
Heat flow is a geothermal parameter for indicating the heat source distribution and evaluating geothermal reservoirs. Only 1,230 heat flow points are distributed unevenly in China, mainly concentrated in high‐temperature geothermal and southeast regions.
