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.

Comparative Study Among Hybrid Ground Source Heat Pump System, Complete Ground Source Heat Pump and Conventional HVAC System [PDF]
Volume 4: Energy Systems Analysis, Thermodynamics and Sustainability; Combustion Science and Engineering; Nanoengineering for Energy, Parts A and B, 2011 In this paper, a hotel with hybrid geothermal heat pump system (HyGSHP) in the Pensacola is selected and simulated by the transient simulation software package TRNSYS [1]. To verify the simulation results, the validations are conducted by using the monthly average entering water temperature, monthly facility consumption data, and etc.
