卫生热水蓄热方式对地埋管换热性能的影响分析

he vertical U-tube ground-coupled heat pump system provides cold and heat for the controlling of indoor environment. Under the air-conditioning condition, the vertical U-tube ground-coupled heat pump system with heat recovery can provide sanitary hot water. The influence of supplying sanitary hot water on the heat transfer performance of ground heat exchangers will be different under different operating modes in summer and winter. Through a project design of ground-source heat pump system, the influence of supplying sanitary hot water under heat storage mode on the heat transfer performance of ground heat exchangers in summer and winter was respectively analyzed. The dynamic performance of heat exchangers under different working conditions was analyzed, and through numerical calculation, the heat transfer performance parameters of ground heat exchangers under different operating modes were obtained. From the calculation results, the adjusting methods based on the load characteristics of this project were present.
