In this case the PCM-uTES. introduced a positive impact (+25.6%) that was slightly high er than the overall reduction due to. shorter boreholes ( −13.5%) and lower energy demand for heating (− ...
A possible optimization in GSHP design, including a thermal storage device between the ground exchangers and the heat pump, was already realized and it …
To promote communications among researchers on GSHP and UTES, we invite investigators to contribute original research articles and review articles to this special issue. Potential topics include, but are not limited to: Ground source heat pump system (GSHPs) Underground thermal energy storage (UTES) GSHPs integrated with other …
Among these, latent heat thermal energy storage (LHTES) is particularly notable because it utilizes phase change materials (PCMs) as storage media, which provides a high energy density and ...
It''s all in the name: ground source heat pumps — variously called ground source and liquid to water heat pumps — are devices that extract heat from the earth. This geothermal energy can serve to heat buildings and water. It''s usually necessary to first drill a hole in the ground, for example in the home''s garden, before a liquid heat ...
Sensible heat storage (SHS) implies storing thermal energy in a storage media by increasing its temperature and extracting heat using heat transfer fluid (HTF). SHS is widely discussed in the literature, especially in terms of storage material and numerous large-scale projects [ 27, 28 ].
A dual-source heat pump (DSHP) with a hybrid TES and ground heat exchanger (GHE) named dual-purpose underground thermal battery (DPUTB) is …
Ground-source heat pump (GSHP) systems represent an energy efficient technology for heating and cooling of non-residential buildings due to the relatively high and stable heat source...
In this paper, a solar-assisted ground-source heat pump system model is established to investigate the seasonal heat storage heating process. Heat stored in the …
