PURPOSE:To reduce the difference in temperature between a vapor generator and a heat exchanger as well as enhance the feeding performance of heat by positioning the first and second tanks into or from which a working liquid is flowed or discharged above the generator. CONSTITUTION:A working liquid 12 in a collector (or generator) 1 is boiled and vaporized by insolation, and the liquid 12 heated by raising the internal pressure of the collector 1 is pushed through a subtank 14 into a heat exchanger 3 and heat-exchanged with hot water supplied in the heat exchange tank 2. The liquid 12 so cooled is then sent to the first tank 17a. When the level of the liquid 12 in the tank 17a is raised and reaches a given height, the first valve mechanism 18a is pushed up by the first liquid level sensor 6a and becomes opened, and the second valve mechanism 18b is pushed down by the valve controller 19 and becomes closed. The working liquid 12 in the first tank 17a is refluxed to the collector 1 and the liquid 12 cooled by heat exchange in the heat exchanger 3 is flowed into the second tank 17b. |
