摘要
漯河市浅层地热能开发利用方式以水源热泵系统为主,因开发利用前期,大多未进行适宜性评价论证工作,导致后期出现一系列的问题,无法正常运行工作。该文应用层次分析法对漯河市地下水源热泵工程适宜性进行评价。通过调查及钻孔抽水回灌试验,建立层次结构模型,选取含水层富水性、补给模数、地下水开采潜力、含水层岩性、地下水位埋深、含水层回灌能力、矿化度、总硬度和地下水的腐蚀性共9个要素指标进行赋值计算评价。评价结果为漯河市地下水源热泵工程适宜区面积为45.74km2,较适宜区面积为210.71km2,不适宜区面积为274.75km2。本次评价为漯河市水源热泵系统的开发利用提供了理论和技术依据。
The water source heat pump system is the main mode of shallow geothermal energy development and utilization in Luohe City.In the early stage of development and utilization,most of them don’t carry out suitability evaluation and demonstration work,which led to a series of problems in the later stage and can’t work normally.In this paper,the AHP is applied to evaluate the suitability of groundwater source heat pump project in Luohe City.Through the investigation and borehole pumping recharge test,the hierarchical structure model is established,and 9 key indexes including aquifer of water yield,recharge modulus,groundwater exploitation potential,aquifer lithology,groundwater depth,aquifer recharge capacity,salinity,total hardness and groundwater corrosivity are selected for assignment calculation and evaluation.The evaluation results show that the suitable area of water source heat pump of Luohe City is 45.74 km^2,the comparatively suitable area is 210.71 km^2,and the unsuitable area is 274.75 km^2.This evaluation provides theoretical and technical basis for the development and utilization of water source heat pump system in Luohe City.
