Abstract

The invention discloses an air conditioner and a draught fan air volume control method and device thereof. The draught fan air volume control method for the air conditioner comprises the steps that the environment temperature of the environment where the air conditioner is located is collected; the gear of a draught fan of the air conditioner is determined; the duty ratio of the draught fan of the air conditioner is determined according to the environment temperature and the gear of the draught fan; and the air volume of the draught fan of the air conditioner is adjusted according to the duty ratio. By means of the air conditioner and the draught fan air volume control method and device thereof, the problem that in the prior art, the air volume of a draught fan in the air conditioner draught fan adjusting process is not constant is solved, and accordingly the effect of outputting the optimal constant air volume in the air conditioner draught fan adjusting process is achieved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner and a method and device for controlling the air volume of a fan thereof. Background technique [0002] At present, in the process of adjusting the fan air volume of the air conditioner, the control algorithm adopted by the fan is to output a certain duty cycle by adjusting the motor speed, and further drive the fan to work through the duty cycle. The control of the air volume of the fan is realized by jointly determining the fan gear and the static pressure value of the fan. A fixed fan gear and a fixed static pressure value correspond to an air volume value. However, with the use of the air conditioner, due to the dust in the working environment and the failure to clean the air conditioner filter in time, the filter screen of the air conditioner is blocked; on the other hand, when the ambient temperature of the air conditioner changes, the fan is still The pr...
