Thermal imbalance due to application of geothermal energy piles and mitigation strategies for sustainable development in cold regions: a review

  • Maryam Saaly

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 features of the geothermal energy pile, one of the most popular ground heat exchangers (GHEs) which serves two purposes of supporting the structural loads of buildings and providing heat to them, have been reviewed. Thermal imbalance, which is encountered during harness of geothermal energy, is discussed. Then, the potential solutions for alleviating this problem are reviewed. These solutions are divided into two major categories of GHE modification and application of auxiliary heating/cooling units. If feasibility of such solutions is justified, the underground thermal imbalance can be eliminated efficiently.
