Abstract: 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.
