چکیده
To avoid the catastrophic results of climate change, a major shift towards clean, sustainable and renewable energy technologies is inevitable. Since buildings are capable on-site thermal generation exhibiting predictive patterns heating cooling, many attempts currently underway to incorporate more (e.g., geothermal cooling) systems in buildings. Subsurface resources represent great potential for direct use energy; put another way, planet six sextillion (1021) metric ton battery that continually being replenished by solar radiation, lightning, heat from its deep-down molten core. Despite enormous potential, not adopted widely due three main reasons: high drilling costs, imbalance ground, lack space. address these challenges, novel foundation-based exchanger system incorporating phase change material (PCM) has been designed. The proposed technology, utilizing foundation caisson, reduces construction installation costs integrating structural together into single ground installation. present study aims characterize performance through numerical model validated calibrated using experimental data generated demonstration site hosts caisson. Efficacy PCM on improving characterized terms savings greenhouse gas (GHG) emission reduction. Sensitivity studies demonstrate improvement caisson with increased conductivity. Also, as seasonal injection extraction ratio deviates further away unity, helps improve evidenced reduced primary consumption.

Study on the Performance of a Ground Source Heat Pump System Assisted by Solar Thermal Storage
A ground source heat pump system (GSHPS) utilizes a relatively stable underground temperature to achieve energy-saving for heating and cooling in buildings. However, continuous long-term operation will reduce the soil temperature in winter, resulting in a decline in system performance. In this research, in order to improve the system performance of a GSHPS, a ground heat pump system integrated ...
متن کاملCurrent status of ground source heat pumps in Europe
Geothermal Heat Pumps, or Ground Source Heat Pumps (GSHP), are systems combining a heat pump with a ground heat exchanger (closed loop systems), or fed by ground water from a well (open loop systems). They use the earth as a heat source when operating in heating mode, with a fluid (usually water or a water-antifreeze-mixture) as the media transferring the heat from the earth to the evaporator o...

An innovative space-conditioning system is proposed and a life-cycle assessment (LCA) is presented. The layout is obtained starting from a ground-source heat pump system (GSHP) and includes upstream thermal storage (TS). A prototype of the system, implemented following this new approach, is currently in use for space heating and cooling of an industrial building. As a result of the TS designed ...
