description To develop a grain storage energy pile-based quasi-low-temperature storage system that utilizes clean and green geothermal energy to provide low-temperature cooling for grain storage facilities, numerical simulation methods were employed to investigate the effects of heat exchange pipe flow velocity and system operation time on the thermal performance and energy efficiency of the grain storage energy pile system. An optimized operational strategy was proposed to enhance the technical and economic performance of the system, as well as its energy-saving and carbon-reduction capabilities. Taking a grain storage facility in Zhengzhou as a case study, the analysis conducted under summer cooling conditions demonstrated that the flow velocity of the energy pile system significantly influences the heat exchange capacity and energy consumption of the pile. Reasonable control of operation and intermittent periods can not only ensure energy-saving effects but also meet the quasi-low-temperature storage requirements for grain. Compared to the unoptimized scheme, the optimized energy pile regulation scheme reduced energy consumption by 18.7%. Furthermore, when compared to other cooling solutions such as grain cooling machines, air conditioning, and ground-source heat pumps, the energy consumption of the energy pile system was reduced by 65.6%, 45.9%, and 25.0%, respectively.
