Abstract

PURPOSE:To make it possible to commonly use the same blower so as to reduce cost by providing the blower in air conveying duct connected to a solar heat air collector and making switchable an air flow path leading to the solar heat air collector to and from an air flow path through which cool air under the floor leads to the inside of a room. CONSTITUTION:At the time of space heating in the winter season, upstream and downstream changeover dampers 7 and 6 are opened, while upstream and downstream dampers 8 and 9 are closed thereby to form an air flow path through which air leads to a solar heat air collector 1 via an air conveying duct 2. On the other hand, at the time of utilizing cool air under the floor in the summer season, upstream and downstream changeover dampers 8 and 9 are opened and, at the same time, upstream and downstream changeover dampers 7 and 6 are closed thereby to form an air flow path through which cool air under the floor is led to the inside A of a room via a cool air suction duct 4 and a cool air blow-off duct 5. In this manner, the same blower 3 can be commonly used for a blower for use in a solar heat air collector 1 and that for use in suction of cool air under the floor.
