FLEXIBLE DUCT WITH AIR VOLUME REGULATING MECHANISM AND AIR CONDITIONER FACILITY USING IT

摘要

PROBLEM TO BE SOLVED: To reduce a facility cost of a duct facility by attaching a clamper for regulating an air volume to regulate a sectional area of an inner air duct by throttling a flexible duct in such a state that a flexible tube of a constituting material of the duct is radially contracted. SOLUTION: A string-like clamper 9 for regulating a sectional area of an inner air duct 5 by throttling an inside flexible tubular material 7 in a radially contracting state on the way of a flexible duct 5 of a double structure provided with a heat insulator layer 8 between an outside coating material 6 and the material 7 is disposed between the layer 8 and the material 7. Both operating ends 9a of the clamper 9 are extended from a pore 10 formed at the material 6 to an outside of the duct 5. Thus, the cost of the duct facility, and labor and the time required for building the duct facility can be largely reduced.
