Abstract: An air type solar system of the present invention has a heat-collecting unit for heating air by solar heat, and a blower fan for blowing the air as a heat medium from the heat-collecting unit. The blower fan is of a large scale, which is capable of: blowing the air at a rate of about 100 to 2000 m3/hour; and rotating by a direct-current generated from solar cells under normal conditions. In addition, the amount of airflow is confined by an automatic electrical control in winter to adjust the temperature of heat-collected air to an appropriate temperature for heating and humidification. Therefore, the air type solar system of the present invention can be appropriately operated in quest of an effective use of the solar cells while there is no need to use any storage cell.

Abstract: A solar system house having a solar-heat collecting portion on a roof, a solar-heat collecting duct communicated with the solar-heat collecting portion; and a handling box connected to the solar-heat collecting portion. The handling box includes a back-flow damper that prevent a back-flow toward the solar-heat collecting duct, an air-flow change damper that allow selection between a descending duct and an exhaust duct opened to the outside, a solar-heat collecting fan positioned between the back-flow chamber and the air-flow change damper, and a driving motor for rotating the solar-heat collecting fan in the handling box, which is a direct current (DC) motor to be driven by a solar-battery and a rechargeable battery electrically connected to the solar-battery.
