PURPOSE: An organic rankine cycle power generation system using geothermal heat is provided to reduce the enthalpy of the rear end of a turbine by cooling a condenser using geothermal absorption chiller and an engine chiller at the same time. CONSTITUTION: An organic rankine cycle power generation system(100) using geothermal heat comprises an energy supply unit(102), a pre-heater(104), an evaporator(106), a turbine(108), an electricity generating unit(110), a condenser(114), a geothermal absorption chiller(112), an engine chiller(116), a storage tank(118), and a pump(120). The geothermal absorption chiller produces cold energy with geothermal heat, and provides the cold energy to the condenser. The geothermal absorption chiller recovers the cold energy from the condenser, and continuously cools condensed liquid. The engine chiller provides a catalyst to the condenser, and continuously cools the condensed liquid by recovering the catalyst from the condenser. The storage tank stores the condensed liquid supplied through the condenser. The pump pumps the condensed liquid to supply the liquid to the pre-heater.
