| Abstract: | The performance of ground exchanger is the design foundation of ground source heat pump GSHP). ( A experimental system is built by taking into account the different buried methods, which includes the single U- pipeby sand backfill, the double U-pipe ground pipe, and the single U-pipe by concrete backfill. The heat transfer performanceofgroundexchanger is studied fordifferentsoil, different backfill material and different pipe quantity. |
