地下水源热泵热源井布设合理性评价指标体系

Rationality Evaluation Index System on the Design of Heat Source Well for Groundwater Source Heat Pump

目的评价地下水源热泵工程热源井布设的合理性,确立相应的评价标准与方法.为更加合理地布设地下水源热泵工程热源井的实际工程提供参考.方法综合考虑水文地质条件、建筑物冷热负荷条件、周边环境条件等热源井设计影响因素,利用层次分析法确定各影响因素的权重,并运用综合指数法对比评价沈阳市浑南新区(A)和大东区(B)两项地下水源热泵工程的合理性.结果A工程地下水源热泵热源井布设合理性等级为Ⅱ级,较合理;B工程地下水源热泵工程热源井布设合理性等级为Ⅳ级,不合理.结论地下水源热泵工程热源井布设评价方法和评价标准具有一定的针对性和可操作性,可以推广到其他地下水源热泵工程的热源井布设合理性评价,为地下水源热泵系统的设计人员提供了简单和实用的技术方法和设计依据.

This paper is to estimate the rationality of the layout of heat source well in the groundwater source heat pump project,and to establish the corresponding standards and methods. On the basis of comprehensive considerations of the influence factors of hydrogeology,cooling and thermal load of buildings,and surrounding environment,the weight of the various factors were determined by AHP method. The rationality of the layout of heat source well in the groundwater source heat pump project in the Hunnan district（A）and Dadong district（B）of Shenyang was evaluated by composite index method. The reasonable level of the layout of heat source well in the groundwater source heat pump project in the Hunnan district（A）was II,which was reasonable. That in the Dadong district（B）was IV,which was unreasonable. So the corresponding standards and methods ofthe layout of heat source well in the groundwater source heat pump project can be used to other project on estimating the rationality of the layout of heat source well in the groundwater source heat pump project.
