Study of cold / hot stacking problem based on balance storage of ground source heat pump

Based on energy storage balance of soil, the ideas to solve cold / heat stacking problem of the ground-source heat pump(GSHP system were put forward, further concepts of short intermittent operation and long intermittent operation were introduced. The soil temperature recovery of GSHP system with intensive vertical pipe was tested in a residence community during the transition season, relative operation strategy was discussed.
