METHOD AND DEVICE FOR CONTROLLING AIR CONDITIONING DEVICE, AND AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/134439
Kind Code:
A1
Abstract:
A method and device for controlling an air conditioning device, and an air conditioning device. An air outlet is arranged at an indoor unit of the air conditioning device. An air channel in communication with the air outlet is provided therein with a fan and a purification unit used to purify an air flow output from the fan. The air outlet is further provided with a first sensor used to detect an air velocity. The method comprises: controlling a first sensor to detect an outlet air velocity of an air flow after the air flow has passed through a purification unit; determining, for the purification unit, and according to a difference between the outlet air velocity and a reference air velocity, an air amount or an air velocity loss value; and adjusting a rotation speed of the fan according to the air amount or the air velocity loss value. The method enables a rotation speed of a fan to be automatically adjusted according to an air amount or an air velocity loss value, thereby adjusting the amount of air purified, ensuring purification efficiency and performance. Moreover, the rotation speed of the fan changes in accordance with the loss value, thereby preventing high energy consumption as a result of continuous rotation of the fan at a higher speed, and effectively reducing energy consumption.
