Experimental Analysis of Control Modes in the Soil Thermal Energy Storage
The TES in the soil and rock involves a complicated and unsteady process and its effect and capability depend on the operational control.Based on the idea proposed by the authors on reforming and regenerating the ground temperature distribution configuration through subjective controlling and allotting the load,this work focuses on the experimental investigation of heat transfer in the soil tank for storing thermal energy and lays emphasis on researching the effect,temperature scope potential,ground temperature distribution and variety.Four typical operational modes of the load of heat resources (boreholes of underground heat exchanger),i.e.the uniform mode,the concentrative mode,the intermittent mode and the heat shield mode were studied.Thus,a new method of higher conservation efficiency of TES in the soil has been pursued by means of controlling every load of boreholes to enhance the practical maneuverability in UTES.The reformation of temperature distribution has been ideated and presented,and the performance of heat shield has been found to realize higher efficiency and to establish an optimization way for UTES.
