Abstract:Groundwater ground source heat pump system is an effective way to develop and utilize shallow ground temperature energy. To investigate the shallow geothermal energy of the Ordovician limestone of Jingxing County, a thermal response test was conducted to drill a borehole in a valley of Duanzhuang village of Jingxing County. After drilling, a double U-shaped underground pipe was lowered to test the physical mechanics, thermal parameters and geothermal field characteristics of the rock and soil. Eight indicators, including underground water level depth, groundwater flow rate, aquifer thickness, formation lithology, fourth system thickness, thermal conductivity, specific heat capacity and ground temperature, were selected to evaluate the suitability of an underground piped ground source heat pump in Jingxing County, and the evaluation was divided into suitable, more suitable and unsuitable areas. In order to better verify that the shallow geothermal energy contained by the Ordovician limestone of Jingxing County is valuable for development and utilization, the project installed related application projects and monitoring equipment to monitor the energy consumption under different working conditions. By comparing with the energy consumption of ordinary household air conditioning, the relevant conclusions are drawn. |
