Feasibility analysis and suggestion of applying ground-source heat pump system in the Tianjin Binhai New Area

This paper introduces the hydrogeological conditions and characteristics of ground temperature field in the Binhai New Area.Combining with the related policies and features of ground heat pump system and groundwater heat pump system,the feasibility of application of these two different heat pump systems in the study area is analyzed.The main problems include crossing strata,reinjection,land subsidence,heat balance,etc.It is suggested that the rational design must be made for non crossing strata....
