Claims (1)
機の回転速度を制御する空気調和機において、上
記３相給電線のいずれか１相の欠相を検出したと
きに上記インバータへの通電を遮断して上記送風
機の運転を停止させる欠相運転防止回路を設けた
ことを特徴とする空気調和機。 In an air conditioner in which the rotational speed of a blower is controlled by an inverter installed in a three-phase power supply line, when an open phase in any one phase of the three-phase power supply line is detected, power to the inverter is cut off. An air conditioner characterized by being provided with an open-phase operation prevention circuit that stops the operation of the blower.
