PURPOSE:To enable to receive solar heat effectively, by constituting a heat receiving member of a solar-heat receiving wall structure from a metal plate formed with air-permeable apertures, and disposing the heat receiving member in the manner that it kept out of contact with a glass plate and a heat-insulating layer. CONSTITUTION:A heat-insulating layer 3 is disposed on the inside of a glass plate 1 constituting the outer wall surface, by the intermediary of an air layer 2 and in the manner that it extendes in parallel with the glass plate 1, and a heat receiving member 4 made of a metal plate formed with a many air-permeable apertures is disposed in the air layer 2, also in the manner that it extendes in parallel with the glass plate 1. This heat receiving plate 4 is heated to a high temperature by receiving solar heat and rays transmitted through the glass plate 1, so that air in the air layer 2 is heated by the plate 4. Here, since the specific weight of air thus heated becomes small through thermal expansion of the same, it flows upward and is discharged into the inner space of a room from an upper opening 7 via an upper air port 5 formed in the heat-insulating layer 3. At the same time, low-temperature air in the room is drawn into the air layer 2 from a ower opening 8 via lower air port 6, and after being heated, it is carried back into the space in the room. |
