摘要
这项研究深入探讨了使用热技术(包括抽水井和注水井)对地下水系统造成的潜在热影响。我们开发了一种独特的方法,将直接计算与计算机建模相结合,以评估当水流量超过 2 L/s 时的热影响。我们的模型基于一个有两口井和稳定水流的系统,用于确定热技术周围温度变化超过 1 °C 的区域。我们的研究结果表明,通过模型计算得出的基于数据的关系可以谨慎估计受影响区域或 "热云 "的大小。不过,需要注意的是,我们的模型假设可能无法完全考虑现实世界地下水系统中存在的复杂变量。这凸显了进行更多研究和测试的必要性。我们的研究的一个主要贡献是开发了一种新方法,用于评估热泵运行的热影响。总之,虽然我们提出的方法需要更多的微调,但它在估算含水岩层或含水层内的温度变化方面显示出了前景。这对于有效利用热技术,同时确保地下水资源的保护和可持续管理至关重要。
Estimating Thermal Impact on Groundwater Systems from Heat Pump Technologies: A Simplified Method for High Flow Rates
This research delves into the potential thermal effects on underground water systems caused by the use of thermal technologies involving extraction and injection wells. We developed a unique approach that combines straightforward calculations with computer-based modeling to evaluate thermal impacts when water flow rates exceed 2 L/s. Our model, based on a system with two wells and a steady water flow, was used to pinpoint the area around the thermal technology where the temperature varied by more than 1 °C. Our findings suggest that the data-based relationships we derived from our model calculations provide a cautious estimate of the size of the affected area, or ‘thermal cloud’. However, it is important to note that our model’s assumptions might not fully account for the complex variables present in real-world underground water systems. This highlights a need for more research and testing. A key contribution of our study is the development of a new method to assess the thermal impact of operations involving heat pumps. In conclusion, while our proposed method needs more fine-tuning, it shows promise in estimating temperature changes within water-bearing rock layers, or aquifers. This is crucial in the effective use of thermal technologies while also ensuring the protection and sustainable management of our underground water resources.

期刊介绍:
Journal of Hydrology publishes original research papers and comprehensive reviews in all the subfields of the hydrological sciences, including water based management and policy issues that impact on economics and society. These comprise, but are not limited to the physical, chemical, biogeochemical, stochastic and systems aspects of surface and groundwater hydrology, hydrometeorology, hydrogeology and hydrogeophysics. Relevant topics incorporating the insights and methodologies of disciplines such as climatology, water resource systems, ecohydrology, geomorphology, soil science, instrumentation and remote sensing, data and information sciences, civil and environmental engineering are within scope. Social science perspectives on hydrological problems such as resource and ecological economics, sociology, psychology and behavioural science, management and policy analysis are also invited. Multi-and interdisciplinary analyses of hydrological problems are within scope. The science published in the Journal of Hydrology is relevant to catchment scales rather than exclusively to a local scale or site. Studies focused on urban hydrological issues are included.
