PURPOSE:To contrive to effectively utilize solar heat, by a method wherein a heat-absorption and stagnation duct is provided in a meandering form in the interior of a heat-receiving bag capable of transmitting solar heat, thereby effectively collecting solar heat, and a hot air flow is supplied from a feeding-in side of the duct to a drier or the like by a blower. CONSTITUTION:The heat-receiving bag 1 of the hot air flow generating device provided with the heat-absorption and stagnation duct 19 therein is supplied with the outside air by a blower, the outside air passed through the duct 19 while inflating the latter, and the bag 1 is inflated into a semi-cylindrical shape by air ejected from an ejecting part 23. The bag 1 is held by strings 15 provided between fitting parts provided at both end parts 7 and piles 17. When the solar rays are transmitted to an upper heat-receiving film 3 of the bag 1 and air is heated by a lower heat-receiving film 5 and the duct 19, heat is accumulated in air contained in the bag 1. This air is thereafter supplied to a drier separately provided through a hot air passage of an opening part 25 formed in a heat-receiving film 11. |
