PURPOSE:To utilize solar heat energy by changing photo-isomerized latent heat energy into sensible heat energy without disturbing the flow rate of a solar- energy absorbing material flowing in a circulating pipeline, by providing a bypass to the circulating pipeline to absorb and utilize solar energy. CONSTITUTION:A catalyst reactor 7 to change photo-isomerized latent heat energy, which is reserved in a solar energy absorbing material, into sensible heat energy, and a pipeline 14 to bypass a secondary heat exchanger 8 are provided to the titled heat collecting apparatus, and as a means of changing the flow path of a vertical line, connecting the catalyst reactor 7 and the secondary heat exchanger 8 to the bypass line 14, valves 15 and 16 are provided. With such an arrangement, the solar-energy absorbing material can be led into the bypass line 14, in case that the rate of photo-isomerized latent heat energy to be changed into sensible heat energy is decreased, or the change is not necessary, or the photo-isomerized latent heat energy is to be accumulated and reversed in the solar energy absorbing material without changing it into sensible heat energy. |
