PURPOSE:To eliminate the power such as a fan and to enable saving of energy, by a method wherein the air heated at a heat collecting space is naturally circulated, in order, through a guide duct at an upper surface side of a sitting room, a radiating duct and a guide a duct at the bottom surface side of the sitting room. CONSTITUTION:A heat collecting space 4 collects the solar heat through heat collecting glass plates 3, 3, the air heated in the heat collecting space 4 heats sitting rooms 5 and 6 at the south side of the first and second floor through auxiliary heat collecting glass plates 7, 7, and rises upward. With the elapse of time, warm air in the heat collecting space 4 is increased in temperature, and an internal pressure increases. Meanwhile, since the inside of a radiating duct 18 at the north side irradiated with no sun light is cool, air gathers at the lower part and a pressure is low. The warm air in the heat collecting part 4 inevitably flows in an upper guide duct 13, and is guided to the radiating duct 18. A part of warm air flows in a central guide duct 15 through dampers 15a and 15b being opened, and is guided to the radiating duct 18. Thus, the sitting rooms 6 and 12 at the south side and the north side of the second floor are heated also from a ceiling surface and a floor surface, and the sitting rooms 5 and 14 at the south side and the north side of the first floor are heated from a ceiling by a natural radiation. |
