โœฆ Synopsis

The underground two-dimensional symmetry temperature ยฎeld of a vertical double spiral coil ground heat exchanger (GHX) designed by the authors for a ground source heat pump (GSHP) system was simulated using the volume-control method. A heat transfer model of underground coil is made, and the underground temperature distribution of the coil was solved numerically. Experimental temperature data are measured. The analytical results are compared thoroughly with the experimental data. The mathematical mode presented herein may provide design guidance for the design of GHX for GSHP systems.

Validation of ground heat exchanger (GHE) model is presented using the experimental data obtained for both single and double pipe horizontal GHE. Sensitivity analysis of the GHE model shows the influence of the variation in the soil thermal conductivity, specific heat and density on the thermal perf
