| Abstract: | The effect factors with underground heat exchanger in soil source heat pump system have been studied,three methods to estimate soil thermal properties have been analysed and find that the value tested by in situ method is most accurate.And experimental installation has been built to test the heat exchange amount of underground heat exchanger.It is found that indoor load and the circulating flow mass of heat exchanger tube make significant effect on the heat exchange amout between underground heat exchanger and soil.Utilizing the cylindrical heat source model to simulate the heat exchange process,the simulated results tally with the experimental data. |
