Problems solved by technology

For option ②, although the compressor is over-current protected, as long as the compressor load is reduced, the compressor can continue to run when the current is reduced. Direct shutdown processing will lead to a significant reduction in the comfort experience of the air conditioner.
[0004] For the above-mentioned problems caused by the overcurrent protection of the compressor, the prior art does not provide an effective solution

Embodiment 1

[0044] An embodiment of the present invention provides an air conditioner operation control method, such as figure 1 As shown, the air-conditioning operation control method includes:

[0045] S101, when an abnormal compressor occurs in an outdoor unit of the air conditioner, restart the abnormal compressor one by one;

[0046] S102. During successive restarts, sequentially reduce the operating parameter values ​​of the abnormal compressor to find the safe operating range of the abnormal compressor;

[0047] S103, when found, stop restarting and control the abnormal compressor to operate in the safe operating range;

[0048] S104. When not found, control the abnormal compressor to stop running.

[0049] The abnormality may be that the compressor is in the state of overcurrent protection. The operating parameter values ​​include operating frequency values ​​and / or operating current values. Successively can also be described as sequentially.

[0050] In the embodiment of the...

Embodiment 2

[0098] An embodiment of the present invention provides an air conditioner operation control device, and the air conditioner operation control device includes:

[0099] The restart module 20 is used to restart the abnormal compressors one by one when abnormal compressors appear in the air conditioner-outdoor unit;

[0100] The adjustment module 22 is used to sequentially reduce the operating parameter value of the abnormal compressor during successive restarts, so as to find the safe operating range of the abnormal compressor;

[0101] The control module 24 is configured to stop and restart the abnormal compressor and control the operation of the abnormal compressor in the safe operating range when it is found; and control the abnormal compressor to stop running when it is not found.

[0102] Optionally, the adjustment module 22 is specifically configured to reduce the operating parameter value of the abnormal compressor according to the preset parameter adjustment value during...

Embodiment 3

[0116] An embodiment of the present invention provides an air conditioner, which includes the air conditioner operation control device described in Embodiment 2.

Abstract

The invention discloses an air conditioner operation control method and device, an air conditioner and a storage medium. The air conditioner operation control method comprises the steps of restarting an abnormal compressor gradually when the abnormal compressor occurs in an outdoor unit of the air conditioner; in the successive restart process, reducing operation parameter values of the abnormal compressor sequentially to find the safe operation range of the abnormal compressor; when the safe operation range is found, stopping restarting and controlling the abnormal compressor to operate in the safe operation range; and when the safe operation ranger is not found, controlling the abnormal compressor to stop running. According to the air conditioner operation control method provided by the invention,when the safe operation range of the abnormal compressor is found, the abnormal compressor is controlled to operate in the safe operation range, and when the safe operation range is not found, the abnormal compressor is controlled to stop, so that the problem that when the compressor is abnormal, the comfort experience of the air conditioner is greatly reduced due to unreasonable air conditioner processing schemes or the compressor is completely damaged due to the fact that the compressor is forced to operate within an unsafe operation range is solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner operation control method, a control device, an air conditioner and a storage medium. Background technique [0002] Compressors often stop running due to overcurrent protection caused by excessive current. There are many reasons for over-current protection. In addition to the compressor itself, it is often caused by abnormal wear and tear. After the over-current protection occurs, the existing air-conditioning product solutions mainly include: ① Ignore the fault, restart the compressor directly to continue running; ② consider the compressor to be damaged, and stop it. [0003] For scheme ①, the overcurrent protection still exists after the compressor is restarted, and if it continues to restart, the failure of the unit cannot be dealt with in time, and it will eventually be damaged. For option ②, although the compressor is over-current protect...
