英文摘要In previous studies, the amount of exploitable shallow geothermal energy was estimated by assuming a uniform temperature drop of 2-6 degrees C in the aquifer. In this work, a more comprehensive numerical model has been employed to evaluate the available amount of shallow geothermal energy by using Borehole Heat Exchanger coupled Ground Source Heat Pump systems. Numerical experiments have been performed by simulating the long-term evolution of the subsurface temperature field, which is subject to the operation of borehole heat exchangers and varying parameters like subsurface thermal conductivity and groundwater flow velocity. The concept of equivalent temperature drop is proposed as an auxiliary quantity for the subsurface. With the help of this parameter, a procedure has been established to quantify the amount of shallow geothermal potential. Following this approach, a realistic equivalent temperature reduction is found to be from -1.8 to -4.4 degrees C in the subsurface over a period of 30 years. This can be translated to an annual extractable geothermal energy value in a unit surface area, and it ranges from 3.5 to 8.6 kW h m(-2) a(-1). The exact value is site specific and heavily depends on the soil thermal conductivity, groundwater velocity, and borehole arrangement. (C) 2016 Elsevier Ltd. All rights reserved.
