A review of grout materials in geothermal energy

The most critical parameter is the grout's thermal conductivity in which it always presents a proportional relation with the system's efficiency. Numerous factors are involved in this review to ascertain theier impact on the grouts' performance such as flowability, shrinkage, moisture content, freezing, heat capacity, strength, permeability, solubility and thermal imbalance.

On Mathematical Modeling of Slinky Geothermal Heat Systems

Geothermal heat is an energy source that comes from the earth's core that is continu-ously reproduced[9]. For the last thirty years has been used as a low-cost heating source for residential home by the use of geothermal heat pumps which comprise of a unit

Design Considerations for Borehole Thermal Energy

Borehole thermal energy storage (BTES) exploits the high volumetric heat capacity of rock-forming minerals and pore water to store large quantities of heat (or cold) on a seasonal basis in the geological environment. The BTES is a volume of rock or sediment accessed via an array of borehole heat exchangers (BHE). Even well-designed BTES arrays will lose a significant quantity of heat to the

BTES

The capital cost of a large BTES system can be significant, as a large number of geothermal boreholes will need to be drilled, compared to just a few thermal wells for an ATES system. However, the installation cost should be similar to conventional GSHP systems, and the higher COP values will result in a lower total life-cycle cost than a conventional GSHP system.

Commercial geothermal heating and cooling system

GSHP systems work by moving heat, rather than by converting chemical energy to heat as in a combustion process. We all live with heat pumps, the most widely recognized of which is the refrigerator. A refrigerator "pumps" heat from the cold storage area to the room air via a set of heat exchange coils (the condenser coil cage in the back or bottom of the refrigerator).

Thermal imbalance due to application of geothermal

Due to population growth and increasing energy demand all over the world, geothermal energy, which can be extracted from both deep and shallow geothermal resources, is widely applied in recent years. In the current paper, application of shallow geothermal energy using ground-source heat pump system is assessed and different elements of this system are introduced. Furthermore, different
