PURPOSE:To enable to use upward flow of heated air directly for space heating and to use downward flow of cool air directly for space cooling, by connecting a lower air inlet port of an air passing layer formed inside a roof and one end of an air type radiation panel to each other, and connecting an air outlet port at an upper portion of said air passing layer and one end of the air type radiation panel to each other. CONSTITUTION:In winter, an opening 9 is closed by closing a valve 13 by lossening a control wire 15, and at the same time, an opening 10 is opened by opening a valve 14. In this state, air is heated in an air passing layer S formed inside a roof and flows upward. Then, the heated air is introduced into side chambers P via a connecting port 4 and a connecting port 6 of a terminal box Y and then carried into a central chamber R by forcing an opening 10 of a partition plate 8 and a check valve 12. Thereafter, air is introduced into radiation panels A, B via a connecting port 7 and a duct 16 and then drawn again toward the lower portion of the air passing layer S. Since the valve is closed in the night by the downward flow of air, stationary layer of air is formed and serves as an effective heat-insulating layer. In summer, on the other hand, the valve 13 is opened for passing downward flow of cool air produced in the night, and a valve 11 serves to prevent intrusion of air heated in the daytime and flowing upward through the layer S. |
