Air conditioner fresh air control method and device, electronic equipment and storage medium
PendingCN114838482AProblems affecting normal operationMechanical apparatusLighting and heating apparatusMotor speedElectric machinery
The invention discloses an air conditioner fresh air control method and device, electronic equipment and a storage medium. On one hand, according to the fresh air control method of the air conditioner, the fresh air motor rotating speed serving as the reference value can be determined according to the room attribute of the target room, then the fresh air motor rotating speed is corrected according to the pollutant concentration of the target pollutant in the target room, and the target motor rotating speed is obtained; and it is guaranteed that when the target air conditioner adopts the target motor rotating speed as the working rotating speed to conduct fresh air control, the target pollutants in the target room can be removed. And on the other hand, the whole step of calculating the rotating speed of the target motor is divided into two steps, and the problem that when the rotating speed of the target motor is calculated according to multiple parameters at the same time, consumed calculation resources are too large, and normal operation of the target air conditioner is affected is solved.
