| Abstract: | In this paper,a theoretical model is pressnted for a describing the real storing process of solar energy for a borehole solar energy storage unit in summer season. With numerical methods, the study is focused on investigating the thermal behaviors of this model. The variations in temperature of heating fluid along the borehole channel and time rate of heat storage of the heat storage unit as well as the transient temperature distributions in the unit body are investigated in detail. Through this study, the thermal coupling between heat conduction in the unit body and convective heat exchange of healing fluid has been revealed. |
