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.
