Abstract:Shallow geothermal energy is a new type of renewable energy source. In recent years, the development and utilization of shallow geothermal energy has been highly valued by the local government of Yantai city. Based on systematic collection of basic geology, hydrogeology, geothermal geology and other materials in urban area of Yantai city, the conditions for the development and utilization of shallow geothermal energy have been basically identified by using pumping test, recharge test and on-site thermal response test. By using analytic hierarchy process and fuzzy mathematics method, the suitability of the development and utilization of groundwater source heat pump and groundwater source heat pump have been evaluated. The districts of Yantai city can be divided into suitable areas, rather suitable areas and unsuitable areas. Shallow geothermal energy reserves of each subarea have been estimated, and the heat transfer power of groundwater source heat pump and ground pipe source heat pump in winter and summer have been calculated. It will provide accurate and reliable basic data for promoting energy saving and emission reduction and the conversion of new and old energy in Yantai city.
