PURPOSE:To permit to omit beveling process and protect the peripheral rim thereof by attaching a spacer to the circumference of a light permeating plate. CONSTITUTION:The spacer 4 is provided with rectangular section and is consisting of a continuous base body 21 of an elastic material such as rubber, synthetic resin or the like having continuous same configuration while the continuous base body 21 is provided with a recessed groove 22 on the inner surface and a notch of 45 deg. on the corner thereof and is attached continuously to the whole periphery of the light permeating plate 5. Solar heat, passing through the light permeating plate 5, is collected into a heat collecting body 2 and air, from an air inlet port 20, is heated and, thereafter, is discharged from an air outlet port 19 into a room R whereby the room is air-conditioned. The upper part of the device is arranged with two layers of light permeating plates 5 and the air, whose temperature becomes high by the temperature increase from the inlet port 20 to the outlet port 19, is discharged out of the outlet port 19 under preventing the dissipation of heat by a heat insulating layer between the light permeating plates 5, 5 thereby increasing the utilizing efficiency of the solar heat. The light permeating plates 5 are protected by a spacer 4, danger upon handling may be prevented, the beveling process of the peripheral rim may be omitted and an impact force due to contacting may be mitigated. |
