Study of Feasibility of Underground Cooling Condenser for Geothermal Power Cycles

Abstract:

This paper describes the heat exchanger (condenser) of underground cooling is likely to be technically feasible for geothermal power cycles, i.e. burying the condenser below the ground, instead fan and cooling tower. Through mathematical and ANSYS analyses, the same result T_surface＞T_amb was obtained; otherwise more heat is entering the soil (650w/m) than leaving it to atmosphere (250w/m) has been achieved, which validated heat in the working fluid may then be rejected to the soil and in turn dissipated to the atmosphere.
