Abstract

To monitor the soil temperature field of a ground source heat pump project in Changchun and research their variation and influencing factors. Research showed that: the soil temperature field with the heat pump heating/cooling alternate operation present a periodic variation. The impact of outdoor temperature on the soil temperature field gradually weakened with the increase of the depth and after -10m the change tend to be the same. In transition season soil self-recovery capability is very limited, ground source heat pump system under the condition of cold and hot load imbalance to run for a long time inevitable emergence of thermal imbalance phenomenon.
