Description

technical field [0001] The invention belongs to the field of ground source thermophysics and relates to thermal response testing equipment for rock and soil bodies. Background technique [0002] Ground source heat pump technology has been widely used at home and abroad for its advantages of energy saving and environmental protection. However, in the process of popularization and application of this technology, it faces an important technical problem, that is, the determination of the thermal physical parameters of the formation. At present, the thermal physical parameters of the ground used in the design of many ground source heat pump systems come from indoor test data, and even a considerable part of the engineering design only relies on experience and estimation. -2005, 2009 edition) was revised to increase the requirements for in-situ thermal response testing. [0003] The thermal response test is a test method that compares the actual test data with the theoretical cal...
