Evaluation method of soil thermal property for shallow ground thermal energy utilization

摘要

This study aims at analyzing the shallow ground soil thermal property to contribute to the research on shallow thermal energy utilization and the design work, simulation work on the high-performance ground heat exchanger. In this paper, the calculation and simulation method were introduced firstly. Then the author conducted the simulation using STREAM V14.1 and analyzed the result of two types of arrangements of the ground probe. According to the simulation result, the field experiment was conducted in Sapporo. Finally, the measurement result of the shallow thermal property was compared with the simulation result and revealed the relationship between the surface temperature and thermal performance of shallow ground soil.
