【Abstract】 Energy sources can be used more effectively through the addition of short term and long term energy storage.Underground thermal energy storage(UTES) systems involve complicated unsteady processes,including energy injection,accumulation,storage and extraction.The progress of UTES and frontier research work were discussed in this paper.Through the experiment investigation and the model simulation of the heat transfer of vertical borehole heat exchanger,the effect of thermal storage was studied.Results show that the thermal energy storage will change the level and the distribution of energy and temperature,and the variation of the level will change with the time.The investigation of UTES way lead to a better theoretical understanding and promote the application of UTES in the future,especially in China.更多还原
