Abstract

This paper presents the application of shallow geothermal energy for direct use in the world, and a research background has been reviewed by 2015. The distribution of thermal energy used is approximately 55.3% for terrestrial thermal pumps, 20.3% for water treatment, 15% for space heating, 4.5% for greenhouses and outdoor heating, 2% for Aquaculture ponds and crematorium heating, 1.8% for heating industrial processes, 0.4% for melting and cooling, 0.4% for drying agricultural products and 0.3% for other uses. An annual energy savings of 350 million barrels of oil will prevent the release of 46 million tons of carbon and 148 million tons of CO2 in space. In the following, a brief review of the creation of a shallow geothermal energy market is presented. One of the methods in Barcelona, Spain, is to create a GIS framework for a spatial database and store the main information needed to manage SGE systems such as groundwater velocity, thermal conductivity or thermal heat capacity, and a set of GIS tools to define. Implementation and control. The heat exchange rate and thermal impairment are calculated on the basis of the analytical solutions of porous heat transfer equation.
