PURPOSE:To eliminate the necessity for positioning a high-temperature fluid passage and a low-temperature fluid passage adjacent to each other so as to facilitate the piping work by heightening the vapor pressure inside a fluid medium storage section which is equipped with an internal vapor pressure heightening device. CONSTITUTION:The fluid medium inside a pressure generator 21 is vaporized by being heated by solar heat, and the gasified fluid medium inside the pressure generator 21 flows into a fluid medium storage section 2 through a pressurizer 24, the vapor pressure inside of which rises to permit the recovery of the waste heat. When the liquid medium which has been collected inside a liquid return passage 6 after being liquefied while passing through a low-temperature fluid side heat exchanger 3 is supplied to the fluid medium storage section 2, the vapor pressure inside a high-temperature fluid side heat exchanger 1 and the vapor pressure inside the fluid medium storage section 2 are equalized to allow a part of the fluid medium inside the high-temperature fluid side heat exchanger 1 to flow by virtue of gravity into the pressure generator 21 through a fluid medium supply passage 22, and so, it becomes unnecessary to position the high- temperature liquid passage and low-temperature fluid passage adjacent to each other. |
