[0001] This application relates to the field of air conditioning control technology, and in particular to an air conditioning control method, electronic device, and computer-readable storage medium. Background Technology

[0002] Inverter air conditioners require a maximum frequency limit during operation to protect the unit and prevent overload damage. Traditional methods typically involve pre-setting multiple temperature and voltage ranges to limit the corresponding maximum frequency. However, this approach still carries the risk of damage due to inappropriate frequency limiting at high ambient temperatures, impacting the air conditioner's reliability. Therefore, improving the reliability of air conditioner operation has become a pressing issue. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this application, not all embodiments, and different implementation methods can be adaptively combined. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

The term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, "many" in this paper means two or more.

[0016] Please see Figure 1 , Figure 1 This is a flowchart illustrating one embodiment of the air conditioner control method of this application. The method includes:

[0017] S101: Obtain the current temperature of the environment where the air conditioner is located and the current input voltage of the air conditioner.

[0018] Specifically, it acquires the current temperature of the environment where the air conditioner is located and the current input voltage of the air conditioner in real time.

[0019] In one application, the current temperature of the environment where the air conditioner is located is collected in real time by a temperature sensor, and the current input voltage of the air conditioner is collected in real time by a voltage acquisition module, thereby obtaining the current temperature transmitted in real time by the temperature sensor and the current input voltage transmitted in real time by the voltage acquisition module.

[0020] In another application, a temperature and humidity monitoring system installed in the environment where the air conditioner is located is used to collect the current temperature of the air conditioner in real time. A smart power detection instrument installed in the power supply circuit of the air conditioner is used to collect the current input voltage of the air conditioner in real time. The current temperature and current input voltage are aggregated and transmitted through a concentrator, thereby obtaining the current temperature and current input voltage transmitted in real time by the concentrator.

[0021] In one application mode, the current temperature and current input voltage can be obtained according to a preset sampling interval, and then steps S102 and S103 are executed.

[0022] S102: Determine the maximum safe operating frequency of the air conditioner compressor based on the current temperature and current input voltage.

[0023] Specifically, the maximum safe operating frequency of the air conditioner compressor is obtained based on the current temperature and the current input voltage.

[0024] In one application, a mathematical function relationship between temperature, voltage, and the maximum safe operating frequency is established in advance through theoretical derivation or data fitting. This allows the maximum safe operating frequency to be calculated directly from the current temperature and current input voltage using mathematical formulas.

[0025] In another application, a three-dimensional mapping table of "temperature-voltage-maximum safe operating frequency" is pre-established through experiments or theoretical analysis. This allows the maximum safe operating frequency to be obtained by directly looking up the table matching results based on the current temperature and current input voltage.

[0026] If the air conditioner compressor operates at a frequency exceeding the maximum safe operating frequency, there is a risk that the air conditioner compressor may overload and burn out.

[0027] S103: Controls the air conditioner compressor to operate between the minimum operating frequency and the maximum safe operating frequency.

[0028] Specifically, the air conditioner compressor is controlled to operate between the minimum operating frequency and the maximum safe operating frequency in order to limit the risk of air conditioner damage caused by unreasonable compressor frequency.

[0029] The minimum operating frequency of the air conditioner compressor is preset.

[0030] In one application method, the air conditioner compressor is controlled to operate between the minimum operating frequency and the maximum safe operating frequency using a closed-loop regulation method.

[0031] In another application, the operating frequency of the air conditioner compressor is directly locked between the minimum operating frequency and the maximum safe operating frequency through a hardware protection circuit.

[0032] As can be seen from the above, this application monitors the current temperature of the environment where the air conditioner is located and the current input voltage of the air conditioner in real time, and then determines the maximum safe operating frequency based on the current temperature and current input voltage. This ensures that the air conditioner compressor operates within a safe range under different temperatures and input voltages, avoiding the risk of burnout due to electrical overload caused by use under high temperature and low voltage conditions. This ensures the safety of air conditioner use and improves the reliability of air conditioner operation.

[0033] Please see Figure 2 , Figure 2 This is a flowchart illustrating another embodiment of the air conditioner control method of this application. The method includes:

[0034] S201: Obtain the current temperature of the environment where the air conditioner is located and the current input voltage of the air conditioner.

[0035] Specifically, it acquires the current temperature of the environment where the air conditioner is located and the current input voltage of the air conditioner in real time.

[0036] In one implementation scenario, step S201 specifically includes: determining the temperature of the environment where the outdoor unit of the air conditioner is currently located as the current temperature.

[0037] Specifically, the current temperature is determined by the real-time temperature of the environment where the outdoor unit of the air conditioner is located.

[0038] In other implementation scenarios, the temperature of the environment in which the indoor unit of the air conditioner is located can also be determined as the current temperature.

[0039] S202: Determine the maximum safe operating frequency based on the current temperature and current input voltage.

[0040] Specifically, the maximum safe operating frequency of the air conditioner compressor is obtained based on the current temperature and the current input voltage.

[0041] In one implementation, please refer to Figure 3 , Figure 3 yes Figure 2 A flowchart illustrating one embodiment of step S202. Step S202 specifically includes:

[0042] S301: In response to the current temperature being less than or equal to the rated ambient temperature of the air conditioner, and the current input voltage being less than the rated input voltage of the area where the air conditioner is currently located, the maximum safe operating frequency is determined based on the compressor's maximum operating frequency, the air conditioner's rated input voltage, the current input voltage, and the voltage correction factor; wherein, the voltage correction factor is related to the rated input voltage and the maximum operating frequency.

[0043] Specifically, when the current temperature is less than or equal to the rated ambient temperature of the air conditioner, and the current input voltage is less than the rated input voltage of the area where the air conditioner is located, the current temperature limiting frequency is invalid, while the current input voltage limiting frequency is valid. In this case, the maximum safe operating frequency is determined based on the compressor's maximum operating frequency, the air conditioner's rated input voltage, the current input voltage, and the voltage correction coefficient.

[0044] The maximum operating frequency of the air conditioner's compressor is preset.

[0045] In one implementation scenario, step S301, which determines the maximum safe operating frequency based on the compressor's maximum operating frequency, the air conditioner's rated input voltage, the current input voltage, and the voltage correction coefficient, specifically includes: determining the first difference between the rated input voltage and the current input voltage; determining the first product of the first difference and the voltage correction coefficient; and determining the difference between the maximum operating frequency and the first product to obtain the maximum safe operating frequency.

[0046] Specifically, the first difference between the rated input voltage Ue and the current input voltage Us is calculated, i.e., (Ue-Us). The first product of the first difference and the voltage correction coefficient B is calculated, i.e., (Ue-Us)*B. The difference between the maximum operating frequency FH ​​and the first product is determined, and the maximum safe operating frequency Fm is obtained. The specific calculation process is as follows:

[0047] Fm=FH-(Ue-Us)*B (1)

[0048] It should be noted that the voltage correction factor is related to the rated input voltage and the maximum operating frequency. The rated input voltage is related to the region where the air conditioner is located. For example, the rated input voltage includes 220V and 115V. When the value is 220V, the voltage correction factor ranges from 0.6 to 1. When the value is 115V, the voltage correction factor ranges from 1.2 to 2. The higher the maximum operating frequency of the air conditioner, the higher the specific value of the voltage correction factor. Furthermore, the maximum operating frequency of the air conditioner is related to the type of air conditioner.

[0049] In some implementation scenarios, the rated input voltage of the air conditioner fluctuates. If the current input voltage falls within this fluctuation range, the current input voltage frequency limit is invalid. For example, if the fluctuation range is 10%, meaning the rated input voltage fluctuates between 198V and 242V or between 104V and 126V, then if the rated input voltage fluctuates between 198V and 242V and the current input voltage is 200V, the current input voltage frequency limit is invalid. In other words, there is no need to calculate the maximum safe operating frequency based on the rated input voltage, the current input voltage, and the voltage correction factor; the maximum safe operating frequency is the same as the maximum operating frequency. However, if the current input voltage is 195V, the current input voltage frequency limit is still valid, meaning the maximum safe operating frequency still needs to be calculated based on the rated input voltage, the current input voltage, and the voltage correction factor.

[0050] S302: In response to the current temperature being greater than the rated ambient temperature of the air conditioner and the current input voltage being greater than or equal to the rated input voltage, determine the maximum safe operating frequency based on the compressor's maximum operating frequency, the air conditioner's rated ambient temperature, the current temperature, and the temperature correction factor; wherein, the temperature correction factor is related to the maximum operating frequency.

[0051] Specifically, when the current temperature is greater than the rated ambient temperature of the air conditioner and the current input voltage is greater than or equal to the rated input voltage, the current temperature limiting frequency is effective, while the current input voltage limiting frequency is ineffective. In this case, the maximum safe operating frequency is determined based on the compressor's maximum operating frequency, the air conditioner's rated ambient temperature, the current temperature, and the temperature correction coefficient.

[0052] In one implementation scenario, step S302, which determines the maximum safe operating frequency based on the compressor's maximum operating frequency, the air conditioner's rated ambient temperature, the current temperature, and the temperature correction coefficient, specifically includes: determining a second difference between the current temperature and the rated ambient temperature; determining a second product of the second difference and the temperature correction coefficient; and determining the difference between the maximum operating frequency and the second product to obtain the maximum safe operating frequency.

[0053] Specifically, calculate the second difference between the current temperature Tc and the rated ambient temperature Te, i.e., (Tc-Te). Calculate the second product of this second difference and the temperature correction factor A, i.e., (Tc-Te)*A. Determine the difference between the maximum operating frequency FH ​​and the second product to obtain the maximum safe operating frequency Fm. The specific calculation process is as follows:

[0054] Fm=FH-(Tc-Te)*A (2)

[0055] It should be noted that the temperature correction factor is related to the maximum operating frequency. The value of the temperature correction factor ranges from 1.2 to 2.2. The higher the maximum operating frequency of the air conditioner, the higher the specific value of the temperature correction factor.

[0056] S303: In response to the current temperature being higher than the rated ambient temperature of the air conditioner and the current input voltage being lower than the rated input voltage, the maximum safe operating frequency is determined based on the compressor's maximum operating frequency, the air conditioner's rated input voltage, the current input voltage, the air conditioner's rated ambient temperature, the current temperature, the voltage correction factor, and the temperature correction factor.

[0057] Specifically, when the current temperature is higher than the rated ambient temperature of the air conditioner and the current input voltage is lower than the rated input voltage, the current temperature limiting frequency is effective, and the current input voltage limiting frequency is also effective. At this time, the maximum safe operating frequency is determined based on the compressor's maximum operating frequency, the air conditioner's rated input voltage, the current input voltage, the air conditioner's rated ambient temperature, the current temperature, the voltage correction factor, and the temperature correction factor.

[0058] It should be noted that since the temperature changes in real time, if the current temperature initially collected is higher than the rated ambient temperature, then after a few seconds it becomes lower than the rated ambient temperature, and then after a few more seconds it becomes higher than the rated ambient temperature again, the process of limiting the frequency based on the current temperature will become cumbersome. Therefore, in order to improve the calculation efficiency, a time condition needs to be added, that is, the current temperature limiting frequency will only be invalid when the current temperature is lower than or equal to the rated ambient temperature within a preset time period. The voltage will also change in real time, and the same applies to the temperature, so it will not be elaborated here.

[0059] In one implementation scenario, step S303, based on the compressor's maximum operating frequency, the air conditioner's rated input voltage, the current input voltage, the air conditioner's rated ambient temperature, the current temperature, the voltage correction coefficient, and the temperature correction coefficient, specifically includes: determining the third difference between the rated input voltage and the current input voltage, and determining the fourth difference between the current temperature and the rated ambient temperature; determining the third product of the third difference and the voltage correction coefficient, and determining the fourth product of the fourth difference and the temperature correction coefficient; determining the sum of the third and fourth products; and determining the difference between the maximum operating frequency and the sum to obtain the maximum safe operating frequency.

[0060] Specifically, the third difference between the rated input voltage Ue and the current input voltage Us, i.e., (Ue-Us), is calculated; the fourth difference between the current temperature Tc and the rated ambient temperature Te, i.e., (Tc-Te), is calculated; the third product of the third difference and the voltage correction coefficient B, i.e., (Ue-Us)*B, is calculated; the fourth product of the fourth difference and the temperature correction coefficient A, i.e., (Tc-Te)*A, is calculated; the sum of the third and fourth products, i.e., (Ue-Us)*B + (Tc-Te)*A, is calculated; and the difference between the maximum operating frequency FH ​​and this sum is calculated, thus obtaining the maximum safe operating frequency Fm. The specific calculation process is as follows:

[0061] Fm=FH- ((Ue-Us)*B+(Tc-Te)*A) (3)

[0062] In one implementation scenario, parameters such as temperature correction factor A, voltage correction factor B, rated ambient temperature Te, and rated input voltage Ue are pre-set in the electrically erasable programmable read-only memory (Eeprom) of the air conditioner's electronic control board.

[0063] In other implementation scenarios, parameters such as temperature correction factor A, voltage correction factor B, rated ambient temperature Te, and rated input voltage Ue can be preset in other memory that can be called. This application does not impose specific restrictions on the type of memory.

[0064] In one embodiment, before step S202, the method further includes: obtaining the operating mode of the air conditioner; in response to the air conditioner operating mode being a heating mode, setting the rated ambient temperature of the air conditioner to a first value; and in response to the air conditioner operating mode being a cooling mode, setting the rated ambient temperature of the air conditioner to a second value, wherein the first value is less than the second value.

[0065] Specifically, when the air conditioner receives the start command, it enters either cooling mode or heating mode. When the air conditioner is in heating mode, the rated ambient temperature is set to a first value, such as 5, 7, or 8. When the air conditioner is in cooling mode, the rated ambient temperature is set to a second value, such as 33, 35, or 36, thus ensuring that the air conditioner adapts to the dynamic needs of different environments in different modes.

[0066] The first and second values ​​are preset.

[0067] In one embodiment, the magnitudes of the first and second values ​​correspond to the specific process of step S201. When the air conditioner is in heating mode, assuming step S201 determines the current temperature of the environment where the outdoor unit of the air conditioner is located, the first value obtained is a. Assuming step S201 determines the current temperature of the environment where the indoor unit of the air conditioner is located, the first value obtained is b. Then a is less than b. Similarly, when the air conditioner is in cooling mode, assuming step S201 determines the current temperature of the environment where the outdoor unit of the air conditioner is located, the second value obtained is c. Assuming step S201 determines the current temperature of the environment where the indoor unit of the air conditioner is located, the second value obtained is d. Then c is greater than d.

[0068] S203: Determine whether the maximum safe operating frequency is greater than the minimum operating frequency.

[0069] S204: In response to the maximum safe operating frequency being greater than the minimum operating frequency, control the air conditioner compressor to operate between the minimum operating frequency and the maximum safe operating frequency.

[0070] Specifically, when the maximum safe operating frequency Fm is greater than the minimum operating frequency FL, the air conditioner compressor is controlled to operate between the minimum operating frequency FL and the maximum safe operating frequency Fm, thereby ensuring that the air conditioner compressor is within a safe operating range, guaranteeing the safe use of the air conditioner, and improving the reliability of the air conditioner operation.

[0071] S205: Otherwise, control the compressor to operate at the minimum operating frequency.

[0072] Specifically, when the maximum safe operating frequency Fm is less than or equal to the minimum operating frequency FL, the air conditioner compressor is controlled to operate at the minimum operating frequency FL, thereby ensuring the cooling or heating effect of the air conditioner.

[0073] To better understand the above solution, let's illustrate it with an example:

[0074] In a specific implementation scenario, an air conditioner with a rated input voltage of 220V is used in cooling mode. The current ambient temperature of the outdoor unit is 45℃, and the current input voltage is 225V. The maximum operating frequency FH ​​of the compressor is set to 80Hz, the minimum operating frequency FL is set to 15Hz, the temperature correction factor A is set to 1.8, and the voltage correction factor B is set to 0.8. First, the current temperature of 45℃ is found to be greater than the rated ambient temperature of 35℃, which meets the temperature limit frequency calculation. The current input voltage of 225V is greater than the rated input voltage of 220V, which does not meet the voltage limit frequency calculation. Therefore, an invalid voltage limit is calculated. The specific calculation process is as follows: Fm = FH - (Tc - Te) * A = 80 - (45 - 35) * 1.8 = 62. It is determined that 62Hz is greater than 15Hz. Therefore, the air conditioner with a current input voltage of 225V, at a current temperature of 45℃, controls the compressor to operate within the safe range of 15Hz-62Hz.
