Control method of air conditioner

Abstract

The invention discloses a control method of an air conditioner. The control method includes the steps of S1, detecting running time and running current of a compressor of the air conditioner, in a refrigerating mode; S2, comparing the detected running current of the compressor to a first preset value; S3, if the detected running current of the compressor is higher than or equal to the first preset value, controlling the speed of an indoor fan of the air conditioner to decrease from a current level to a preset level; if the detected running current of the compressor is lower than a first preset value, returning to the step S2. The preset level of speed is lower than a low level of speed of the air conditioner. The control method has the advantages that when the detected running current of the compressor is higher than or equal to the first preset value, the air level of the air conditioner is switched from the current air level to a current protective air level; the running current of the compressor is effectively decreased, current protection is effectively achieved accordingly, the fact that frequent shutoff of the compressor causes frequent trip of the air conditioner is avoided, and comfort of use is improved for users.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an air conditioner control method. Background technique [0002] The current fixed-speed air conditioner has a current protection function. When the cooling current exceeds a certain set value, the air conditioner will be turned off to play a protective role. In order to avoid frequent protection of the air conditioner and affect the use of the existing air conditioner, Set another current protection value before the current protection needs to shut down the air conditioner. When this protection value is exceeded, the indoor fan of the air conditioner will switch from a higher wind speed to a low wind speed. This method can reduce the operating current of the air conditioner. , so as to play a certain protective role, but due to the requirements of the air conditioner itself, the difference between the high wind gear and the low wind gear of some air conditioners is small, and...

[0002] The current fixed-speed air conditioner has a current protection function. When the cooling current exceeds a certain set value, the air conditioner will be turned off to play a protective role. In order to avoid frequent protection of the air conditioner and affect the use of the existing air conditioner, Set another current protection value before the current protection needs to shut down the air conditioner. When this protection value is exceeded, the indoor fan of the air conditioner will switch from a higher wind speed to a low wind speed. This method can reduce the operating current of the air conditioner. , so as to play a certain protective role, but due to the requirements of the air conditioner itself, the difference between the high wind gear and the low wind gear of some air conditioners is small, and the protective effect is limited when the wind gear is switched.
