<p>PROBLEM TO BE SOLVED: To provide a solar heat utilization system which is small in scale and has a simple structure, and which is not only able to perform heat exchange but also able to generate power.SOLUTION: A closed system is built by: a solar heat collector 2 for heating water by solar heat and generating steam; a condenser 3 for cooling the generated steam and retuning it to hot water having a water temperature near the boiling point; a reservoir 4; a decompressor 5 for performing decompression in the system; a heat exchanger 7 for performing heat exchange between the hot water near the boiling point flowing out of the condenser 3 and another medium; and a pipe 1 for connecting each of these configuration components. The water in the system is circulated by a buoyant force of the steam generated in the solar heat collector 2, and a water turbine power generation unit 6 is rotated by kinetic energy of the water circulating in the system and potential energy utilizing height difference from the condenser 3 to the heat exchanger 7 to generate power.</p> |
