【摘要】Deep — Borehole Heat Exchanger ( DBHE) is generally installed as a co — axial pipe in deep boreholes? The DBHE can obtain heat without extracting groundwater. Literature review shows that the specific heat extraction rate of DBHE is less than 200 W · m^-1 , which is much smaller than that by conventional hydrothermal exploitation systems ? Using both analytical and numerical methods, we evaluated the capacity of DBHE with representative parameters in northern China. Three modeling scenarios were constructed using the simulator OpenGeoSys, including: 1) short—term (4 months) continuous heat extraction;2) short — term heat extraction with half-day intervals;and 3) long — term (30 years) continuous heat extraction. 【总页数】2页(P.110-111)
