<P>PROBLEM TO BE SOLVED: To reduce abnormal noise to be generated when a fan is started, in an air-conditioner including a brushless or sensor-less motor for the fan. <P>SOLUTION: In a vehicle air-conditioner, a blower motor for driving a fan built in a blower unit of a vehicle automatic air-conditioner to be drive-controlled by an automatic air-conditioner ECU is constituted of a sensor-less AC motor. The automatic air-conditioner ECU detects the position of the inside/outside air switching damper when the fan in a running vehicle is started, drives a damper motor to move an inside/outside air switching damper to the predetermined position close to an outside air inlet from an inside air inlet, for example, the outside air inlet closing position, and starts the blower motor after moving the inside/outside air switching damper to the predetermined position. <P>COPYRIGHT: (C)2013,JPO&INPIT |
