[0035] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0036] In the present application, the term "comprising" or "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitation, the element defined by the sentence "including a…" does not exclude the presence of other identical elements in the process, method, article or equipment including the element.

[0037] As known from the background, when the running frequency of the outdoor unit of the air conditioner is too high, due to the increase of the current of the computer board and the insufficient heat dissipation, the power module (Intelligent Power Module, IPM) of the air conditioner will be overheated, resulting in shutdown of the air conditioner, and the user experience is poor.

[0038] Therefore, the embodiments of the present application provide an air conditioner control method, system and related equipment, the monitoring temperature of the power module of the air conditioner is obtained. The monitoring temperature is compared with the recovery point temperature, the frequency reduction point temperature and the air supply point temperature, and the corresponding control mode is determined based on the comparison result, so as to avoid the power module from being overheated and causing the air conditioner to stop, thereby improving the user experience.

[0039] Referring to Figure 1 , a flowchart of an air conditioner control method provided by the embodiments of the present application is shown, the air conditioner control method comprises:

[0040] Step S101: obtaining the monitoring temperature of the power module of the air conditioner.

[0041] In the process of specifically implementing step S101, a temperature sensor arranged at the pin of the power module (IPM) of the air conditioner is called to detect the monitoring temperature (denoted as T0) of the power module; that is, the temperature sensor is arranged at the pin of the IPM, and the monitoring temperature of the IPM is detected by the temperature sensor.

[0042] In some embodiments, the preset air supply point temperature (also referred to as IPM protection value air supply point temperature T1, EE adjustable), the preset frequency reduction point temperature (also referred to as IPM protection value frequency reduction point temperature T2), and the preset recovery point temperature (also referred to as IPM protection value recovery point temperature T3) are written in the E side of the computer board of the outdoor unit of the air conditioner in advance.

[0043] If the monitoring temperature is greater than or equal to the recovery point temperature and less than the frequency reduction point temperature (T3≤T0

[0044] If the monitoring temperature is greater than or equal to the frequency reduction point temperature and less than the supply point temperature (T2≤T0

[0045] If the monitoring temperature is greater than or equal to the supply point temperature (T0≥T1), step S104 is performed.

[0046] Step S102: When the monitoring temperature is greater than or equal to the preset recovery point temperature and less than the preset frequency reduction point temperature, the compressor of the air conditioner is controlled to start the normal frequency conversion mode.

[0047] In the process of implementing step S102, when the monitoring temperature is greater than or equal to the recovery point temperature and less than the frequency reduction point temperature, the compressor of the air conditioner is controlled to start the normal frequency conversion mode, and at this time, the compressor operates according to the normal frequency conversion mode to perform frequency conversion.

[0048] Step S103: When the monitoring temperature is greater than or equal to the frequency reduction point temperature and less than the preset supply point temperature, the frequency of the compressor is reduced.

[0049] In the process of implementing step S103, when the monitoring temperature is greater than or equal to the frequency reduction point temperature and less than the supply point temperature, the frequency of the compressor is reduced to slow down the temperature rise of the power module.

[0050] In some embodiments, a corresponding frequency reduction rule is preset, which defines the frequency reduction values corresponding to each temperature interval; when the monitoring temperature is greater than or equal to the frequency reduction point temperature and less than the supply point temperature, the frequency of the compressor is reduced based on the monitoring temperature and the frequency reduction rule.

[0051] Specifically, when the monitoring temperature is greater than or equal to the frequency reduction point temperature and less than the supply point temperature, the temperature interval in which the monitoring temperature is located is determined; according to the frequency reduction value corresponding to the temperature interval in which the monitoring temperature is located, the frequency of the compressor is reduced to slow down the temperature rise of the power module.

[0052] Step S104: When the monitoring temperature is greater than or equal to the supply point temperature, the supply mode of the air conditioner is run, and step S101 is returned to be executed.

[0053] In the process of implementing step S104, when the monitoring temperature is greater than or equal to the supply point temperature, the outdoor unit of the air conditioner is stopped (the outdoor unit stops working), the supply mode of the air conditioner is run, and step S101 is returned to be executed to continue detecting the monitoring temperature of the power module.

[0054] Understandably, during the process of the outdoor unit stopping work and running in air supply mode, the monitoring temperature of the power module will usually drop. When the monitoring temperature drops below the air supply point temperature, the relationship between the monitoring temperature, air supply point temperature, frequency reduction point temperature and recovery point temperature will be reassessed in order to restore the normal frequency increase / decrease mode of the air conditioner compressor or reduce the compressor frequency.

[0055] In this embodiment of the invention, the monitored temperature of the air conditioner's power module is obtained. The monitored temperature is compared with the recovery point temperature, the throttling point temperature, and the air supply point temperature. Based on the comparison results, a corresponding control method is determined to prevent the air conditioner from shutting down due to overheating of the power module, thereby improving the user experience.

[0056] To better explain the above embodiments of the present invention Figure 1 The content in, through Figure 2 Another flowchart illustrating an air conditioning control method is shown below. Figure 2 Includes the following steps:

[0057] Step S201: Obtain the monitoring temperature T0 of the IPM.

[0058] Step S202: Compare the relationships between T0, T1, T2 and T3.

[0059] In the specific implementation, if T3≤T0<T2, execute step S203; if T0≥T1, execute step S204; if T2≤T0<T1, execute step S205.

[0060] Step S203: Start the normal frequency ramping / deceleration mode.

[0061] Step S204: Run the air conditioner in fan mode and return to step S201.

[0062] Step S205: Reduce the compressor frequency.
