Abstract:
The heat transfer model of the underground heat exchange about the groundwater flow is established based on the line heat source theory,and the dimensionless criterion numbers for similarity of the prototype and scale-model experiment are presented by similarity transformation.The results show that the test time is proportional to square of the length scale Cl2.Moreover,the scale-model experiment platform is built according to the similar criterion numbers,and the long-cycle operation performances of the ground-coupled heat pump system(GCHPs)can be tested by less human and material resources and shorter time through the scale-model experiment platform.
