摘要
为了准确模拟预测地下水源热泵系统运行期间的地下水渗流场与温度场的变化规律,避免未来地下水源热泵系统运行期间出现的冷热贯通现象与堆积问题,科学合理地设计地下水源热泵系统。以江苏南通益兴集团地下水源热泵示范工程为例,建立了地下水渗流与热量运移三维耦合数值模型,并结合地下水源热泵系统的设计运行方案,预测分析了未来地下水源热泵系统的热平衡发展趋势。结果表明,该工程按设计方案运行,整个区域地下水温度逐渐升高,出现热堆积问题。采用春秋季与冬季多加热生活用水增加制热负荷量的方法,可有效缓解热堆积问题。
To accurately simulate and predict variation patterns of groundwater seepage field and temperature field during groundwater source heat pump system runtime, to avoid heat transfixion and heat stack during the runtime in the future, a groundwater source heat pump system has been designed scientifically and rationally. Taking the groundwater source heat pump demonstration project of Nantong Yixing Group, Jiangsu as an example, a 3D coupled numerical model of groundwater seepage and thermal migration has been modeled, combined with groundwater source heat pump system design and operation scheme, predicted and analyzed future groundwater source heat pump system thermal equilibrium development trend. The result has shown that the project running in terms of designed scheme, groundwater temperature gradually rising in whole area, heat stack problem appeared. Using more heating of water for living in spring, autumn and winter to increase heating load capacity, can relieve heat stack problem effectively.
