PURPOSE:To utilize heat generated in a space at the rear side of the roof and contrive energy saving by a method wherein a heat collector is attached to the roof and the other end of a conduit, whose one end is communicated with the space at the rear side of the roof, is opened below the heat collector. CONSTITUTION:The heat collector 5 is disposed near the top of support frame 3 and constitutes a heat medium type solar heat collecting device 4 together with a heat accumulating tank 25 and a heat exchanging unit 26. The conduit 7 penetrates the roof 2 from the inside of the support frame 3 and one end thereof is communicated with the space 6 at the rear side of the roof while the other end thereof is opened below the heat collector 5. A latent heat, included in air flowed from the space 6 at the rear side of the roof for example, and radiant heat obtained when solar beams are projected are exchanged in the unit 26 and whereby water is heated and hot-water may be reserved in the heat accumulating tank 25. The air in the space 6 at the rear side of the roof, whose temperature has becomes high by conducting the heat generated in the roof 2 heated by the radiation heat of sun and the heat generated in a room R, exchanges the heat thereof with the heat collector 5 through the conduit 7 and, thereafter, is discharged into atmosphere. |
