摘　　要：鉴于水源热泵系统中存在一些技术问题未被人们所认识或未引起足够的重视,本文详细阐述了抽灌平衡时地下水动力场及温度场的影响范围估算、抽灌井轮换、水资源保护与热泵效率的关系、抽灌群井布置方式、区域地下水流场对抽灌井布局的影响、浅层地热能储量消耗与热泵的关系、起始运行期选择等七个关于热泵应用的细节技术,为应用水源热泵系统的用户和有关部门提供科学参考,以扬长避短,充分发挥水源热泵系统环保节能的优点。Many specific techniques for groundwater heat pump system are not recognized or are neglected at present. In this paper, seven specific techniques are discussed in detail, including calculation of influence range of groundwater dynamic field for pumping and injection, alternation of pumping wells and injection wells, relationship between groundwater protection and performance efficiency, distribution mode of pumping-injection wells, influence of regional groundwater flow field on well distribution, relationship between shallow geothermal resources depletion and GSHP application and choice of initiative performance period. These problems should be referred scientifically and rationally by the GSHP users and some departments. With this means, the GSHP merit of environmental protection and energy save can be fully exerted, which will be helpful in popularizing the GSHP.

关 键 词：水源热泵系统 地下水动力场 抽灌井布局 浅层地热资源 起始运行期
