摘要
本文以某水源热泵空调系统为例,建立了抽灌场地及周边地下水动力场与温度场的耦合数学模型,运用数值法求得系统运行过程中地下水的温度变化,分析了场地"热短路"效应和不同含水层中温度场的影响范围,以定量化的手段科学评价了场地抽灌井的布局及其可行性。分析结果表明,由于抽灌井之间的"热短路"程度较轻,场地的抽灌井布局可保证系统的高效运行。
Some groundwater heat pumps （GWHP） have low operation efficiency caused by non-rational distribution of pumping-injection wells. In this paper, a numerical model coupled with groundwater level and temperature was established for a site with GWHP and the temperature change was calculated in the process of GWHP operation. Then, the heat penetration and temperature effect range in different aquifer were analyzed, which was based upon assessing the distribution and feasibility of pumping-injection wells. The result shows that the distribution of pumping-injection wells can make heat pump system operate efficiently due to heat short circuit to a light degree.
