Embodiment 1

[0083] Such as figure 2 As shown, the operation control method according to an embodiment of the present invention is used to adjust the speed of the indoor fan, including: Step 202, detecting that the air conditioner is configured to operate at a reduced load according to the operating parameters of the air conditioner. In the load operation state, control to reduce the speed of the indoor fan; step 204, when it is detected that the operation condition of the indoor fan meets the comfort control requirements, then switch the reduced load operation state to the comfortable operation state, and further control to reduce the indoor fan speed in the comfortable operation state. Fan speed.

[0084] In this embodiment, the air conditioner operates according to a specified operation mode. Under the specified operation mode, it includes at least a reduced-load operation state and a comfortable operation state. In both the reduced-load operation state and the comfortable operation st...

Embodiment 2

[0093] Such as image 3 As shown, the operation control method according to another embodiment of the present invention is used to adjust the speed of the outdoor fan, including: Step 302, configure the air conditioner in a reduced-load operation state, and control to reduce the speed of the outdoor fan until it detects The operating conditions of the air conditioner do not meet the adjustment requirements.

[0094] In this embodiment, in the reduced-load operation state, the speed reduction of the outdoor fan can be further controlled, so as to further reduce the power consumption of the air conditioner and reduce the operating noise of the outdoor fan while meeting the temperature control requirements.

[0095] Optionally, it also includes: configuring the lower limit of the speed of the outdoor fan from the third lower limit threshold to the fourth lower limit threshold to further reduce the speed of the outdoor fan; The lower bound reverts to the third lower bound thresho...

Embodiment 3

[0099] Such as Figure 4 As shown, the operation control method according to another embodiment of the present invention is used to adjust the opening of the throttling device, including: step 402, if it is detected that the operating condition of the indoor fan meets the comfort control requirements, enter the comfort operating state, and control to increase the opening degree of the throttling device arranged between the indoor unit and the outdoor unit.

[0100] In this embodiment, the opening degree of the throttling device between the indoor unit and the outdoor unit is controlled to reduce the pressure difference between the indoor unit and the outdoor unit, and the cooling or heating effect is reduced by reducing the pressure difference. The control parameters of the throttling device can be adapted to the speed of the indoor fan and the speed of the outdoor fan to ensure the normal operation of the air conditioner.

[0101] Wherein, the throttling device is specifical...

Abstract

The invention provides an operation control method, an operation control device, an air conditioner and a storage medium. The operation control method comprises the steps that it is detected that according to working condition parameters of the air conditioner, the air conditioner is configured to be in the load-down operation state, and in the load-down operation state, indoor fan rotating speedis controlled to be decreased; and when it is detected that the indoor fan operation condition meets the comfort control need, the load-down operation state is switched to the comfortable operation state, and under the comfortable operation state, the indoor fan rotating speed is further controlled to be reduced. According to the technical scheme, the indoor fan rotating speed is controlled to bereduced, the operation load is reduced, meanwhile, the indoor operation noise is reduced, in the load-down operation state, the indoor fan rotating speed and the outdoor fan rotating speed are furtherreduced, the opening degree is adjusted, after the air is adjusted, the user comfort experience is met, and the operation noise is further reduced.

Description

technical field [0001] The present invention relates to the technical field of household air conditioners, in particular to an operation control method, an operation control device, an air conditioner and a computer-readable storage medium. Background technique [0002] In related technologies, compressor shutdown or frequency reduction is controlled to maintain room comfort requirements and achieve energy saving, but the adjustment method is single and limited by the lower limit of compressor operating frequency, which cannot meet the comfort of all working conditions. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the related art. [0004] Therefore, an object of the present invention is to provide an operation control method of an air conditioner. [0005] Another object of the present invention is to provide an operation control device for an air conditioner. [0006] Another object of the pre...
