<p>PURPOSE:To improve the utilization of heat collection by installing a heat collecting box, the inside of which is surrounded by a heat-insulating layer, to the ridge section of a roof and making the heat collecting box and heat- accumulating and heat-dissipating sections communicate with each other through a duct while interposing a box, into which a blower is incorporated. CONSTITUTION:A colored iron plate 6 and glass plates 10 of a roof 5 heated by solar rays warm air in an air flow path 7 in a solar heat collecting section A. The warmed air rises along a gradient and enters a heat collecting box 21 as a ridge duct while the outside air enters anew into the air flow path 7 from an outside-air intake 8 and is warmed and rises. Heated air generated in the solar heat collecting section A in the roof 5 is collected by the heat collecting box 21, and sent into the air flowing space 33 of a floor 30 through a duct 23 by a blower 25. Warm air in the air flowing space 33 is given moisture by a humidifying pan 40, and blown off into an indoor section C from a warm-air blow-off port 34, thus warm-air heating is obtained. Accordingly, air collecting heat from solar rays can be utilized effectively.</p> |
