| Abstract: |
| With the establishment of mathematical and physical model and numerical simulation of vertical tube by FLUENT, characteristics of buried tube heat exchanger of ground source heat pump (GSHP) was analyzed. Based on this information, combined with the simulation and measurement of summer discontinuous operation results, the law of different buried tube space on the radial variation of soil temperature and coherent effects of buried tubes heat transfer were got. |
| Key words: GSHP buried tube space numerical simulation coherence effects discontinuous operation |
