Exploration and evaluation of shallow geothermal energy

Abstract：The exploitation and utilization of shallow geothermal energy by using the heat pump technology are developing quickly. In order to ensure the rational and sustainable development of shallow geothermal energy, exploration and evaluation are necessary. Through regional survey of shallow geothermal energy, we can ascertain the quantity, quality and distribution of regional geothermal energy at shallow depths to work out a plan for its exploitation and utilization, thus providing a basis for sustainable use of shallow geothermal energy. Exploration of shallow geothermal energy for the ground source heat pump project can offer a reliable basis for the use of shallow geothermal energy for the underground heat exchange system. The environmental evaluation and economical evaluation are the essential content during the exploration. The methods for calculation and assessments of shallow geothermal energy are for the first time put forward systematically in this paper.
