摘要: PROBLEM TO BE SOLVED: To enable a fan rotation speed to be determined even if circumstance around an installation site is inconvenient for determining speed.SOLUTION: This invention relates method executed by duct-type air volume specified control type conditioner so as output prescribed rated volume. Under assumption that the maximum level defined first tap and lower than second tap, driven at search where becomes can searched when it detected state not reaching continued, changing-over executed, of tap.SELECTED DRAWING: Figure 5
