Feasibility Study of a Novel Soil Thermal Recovery Method for HGSHP System

In order to solve the heat accumulation problem of GSHP system in cooling load dominated area with high humidity in summer, this paper presents a novel HGSHP system based on CT cool-storage in transition season. Then the performance evaluation model for HGSHP system is built on the base of the heat and moisture transfer principle of CT, the GHE multiple borehole finite line heat source model and TRNSYS software. At last, using the evaluation model, an actual project in Nanjing is used as an example to predict the thermal performance of this novel HGSHP system. The results show that using novel HGSHP system, the heat accumulation problem can be well solved.
