초록 ▼

A geothermal power system utilizes a fluid refrigerant capable of changing phase between liquid and gaseous states. The system includes a heat exchanger exposed to a heat source such as earth, water, air, or industrial waste for vaporizing the fluid in the heat exchanger. The heat exchanger includes at least two compartmentalized heat exchanger cells. Each of the heat exchanger cells is disposed in a portion of the naturally occurring heat source, the portions being sufficiently spaced apart such that a temperature of any one portion is substantially unaffected by a temperature of any other portion. The vaporized fluid is directed to a turbine or energy extraction means wherein the gas is expanded and energy is re)eased in the form of mechanical rotation of a shaft. The turbine shaft may be coupled to a generator for converting the mechanical rotational energy to electrical power. The gas discharged from the turbine is cooled/condensed and circulated into an accumulator, with a sensor and a controller for continuously maintaining the optimum amount of refrigerant flowing in the system under particular heat source/heat sink conditions. The liquid refrigerant is then recirculated to the heat exchanger, and the process is performed continuously. A compressor and sensored and controlled accumulator may be utilized in a second and separate refrigerant heat exchange loop with compartmentalized heat exchanger cells if necessary to maintain continuous output from the geothermal power system under all temperature conditions.
