主　　题：Vertical borehole ground heat exchanger Pile ground heat exchanger Deep borehole ground heat exchanger Modelling 

摘      要：As a renewable energy source,geothermal energy has been widely used to provide space heating and cooling for *** thermal performance of ground heat exchanger(GHE)is significant for the operating efficiency of the ground source heat pump(GSHP)*** paper presents a comprehensive review of developments and advances of three kinds of GHE,including vertical borehole GHE(VBGHE),Pile GHE(PGHE),and deep borehole GHE(DBGHE)which are currently popular in larger GSHP ***,analytical models proposed to ana-lyze heat transfer process of VBGHE with different geological conditions are summarized,such as homogenous or heterogeneous ground,with or without groundwater *** and short-time step models and measures to improve GHE thermal performance are also ***,a summary of research advances in PGHE is provided,which includes the heat transfer models of PGHE,the effects of geometric structure,oper-ation modes,pile spacing,use of phase change material(PCM),thermal properties of PCM,thermo-mechanical behavior and/or thermal performance of *** effects of groundwater flow direction and velocity on PGHE are also summarized in ***,models of three kinds of DBGHEs,i.e.,deep coaxial GHE(DCGHE),deep U-bend GHE(DUGHE)and super-long gravity heat pipe(SLGHP),are *** physical bases of the dif-ferent analytical models are elaborated and also their advantages and disadvantages are *** in numerical modelling and improving numerical model calculation speed of DCBHE,DCBHE array,and DUBHE are *** review provides a meaningful reference for the further study of GHEs.
