Description
technical field [0001] The invention relates to the field of testing thermal diffusion characteristics of rock and soil, in particular to a testing device for thermal diffusion characteristics of rock and soil under fluid-solid coupling conditions. Background technique [0002] Geothermal resource is a typical clean energy, also known as "green energy" and "renewable energy", which has huge utilization value. Ground source heat pump technology is an environmentally friendly technology that utilizes the near-constant temperature of the shallow underground to obtain "coolness and warmth" from the earth. It is also a common means of utilizing shallow geothermal resources. The ground source heat pump uses the geothermal energy of the shallow soil or water source as a cold (heat) source. In winter, the heat pump unit transfers the low heat energy to the building that needs heating. In summer, the heat pump unit transfers the heat in the building to the building. In the undergrou...
