PROBLEM TO BE SOLVED: To provide a binary power generation system that can also utilize heat of an existing spring hot water or geothermal steam, or geothermal heat of an existing hot spring well with a shallow drilling depth, substantially reducing risk such as scale adhesion and dried-up hot spring, reducing cost and consumption power required for cooling low boiling point medium and capable of performing a high efficient and low cost geothermal power generation.SOLUTION: In a binary power generation system, a closed loop circulation flow path is constituted in such a way that heat source fluid absorbs heat through heat exchanging with geothermal fluid or geothermal heat, heat is radiated through an evaporator and circulated again to perform a heat exchanging with the geothermal fluid or geothermal heat, a closed loop flow path for radiating heat into the ground to perform a cooling action for the cooling fluid for cooling the low boiling point medium is constituted, or a closed loop flow path is constituted such that there are provided a freezer and a heat exchanger in which the heat source fluid after passing through an evaporator is applied as a driving heat source, a temperature of cooling fluid is controlled to supply cooling fluid to a condenser in such a way that the low boiling point medium at the condenser can be optimized so as to supply cooling fluid to the condenser. |
