Summary

Combining with a ground-source heat pump project in severe cold zone, builds two vertical V-tube test wells with depth of 120 m to conduct thermal response test. By using Kelvin's infinite linear source model, calculates parameters of rock-soil thermal properties and capability of ground heat exchanger (GHE). Analyses the thermal resistance characteristics for GHE. Obtains the relationship between extracting cooling capability per well and cooling water temperature under the direct heat exchange condition in summer. Puts forward air conditioning scheme. According to ground heat balance, initial rock- soil temperature, capability of GHE and the year loads, determines the heating and cooling supply schemes of solar coupled ground-source heat pump system.
