| Abstract: | An experimental system of ground source heat pump （GSHP） was established in Changsha where it is hot in summer and cold in winter. The vertical-U ground heat exchangers （GHE） were tested under cooling conditions. The thermo physical properties of soil around GHE were obtained, and the effects of the parameters such as well depth, GHE type and water flow on the system performance were analyzed. The results show that an appropriate GHE type, larger GHE depth and water flow are helpful to increase the heat transfer performance per unit well depth. |
