20150354850 | AIR CONDITIONER AND CONTROL CIRCUIT - Air-blowing from a second air outlet is effectively used. An air conditioner includes a main body unit and an auxiliary housing. The main body unit forms a first air outlet which blows out a cool or warm airflow. The auxiliary housing is attached to at least one side of the first air outlet to be freely movable, and forms a second air outlet which blows out taken-in indoor air. A control circuit blows out the indoor air from the second air outlet at a wind speed which is higher than the wind speed of cool air or warm air that is blown out of the first air outlet. | 12-10-2015 |
20160097558 | METHOD FOR CONTROLLING AIR OUTPUT VOLUME - A method for controlling air volume including: 1) inputting a target air volume into the microprocessor control unit of the motor controller; 2) starting a motor by the motor controller under a torque to enable the motor to work in a steady state; 3) recording the rotational speed in the steady state, and establishing a functional relation formula Q=F (T, n, V) to calculate an air volume in the steady state; 4) comparing the target air volume with the calculated air volume; 5) re-recording a steady rotational speed after the motor falls on a new steady state under an increased or reduced torque, and recalculating the air volume in the new steady state; and 6) repeating steps 4) and 5) to adjust the torque until the calculated air volume is equal or equivalent to the target air volume. | 04-07-2016 |
