[0002] Currently, to ensure operation in areas with poor power supply, the common practice for central air conditioning systems is to add a voltage stabilizer.

[0061] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0064] The air conditioning control method in this embodiment of the invention mainly includes the following steps S1-S2, such as... Figure 1 As shown:

[0065] S1. When the air conditioner is powered on, obtain the current power environment level and the historical power environment level of the air conditioner.

[0066] When the air conditioner is powered on, it first operates with preset operating parameters and obtains the current power environment level and the historical power environment level of the air conditioner.

[0067] In one specific embodiment, the power environment level includes:

[0068] When the actual voltage of the air conditioner meets the following condition: actual voltage < first preset percentage of rated voltage, then the power supply environment level is level one;

[0069] When the actual voltage of the air conditioner meets the following condition: a first preset percentage of the rated voltage ≤ actual voltage ≤ a second preset percentage of the rated voltage, then the power supply environment level is level two.

[0070] When the actual voltage of the air conditioner meets the following condition: actual voltage > second preset percentage of rated voltage, the power supply environment level is level three.

[0071] For example, the rated voltage of the air conditioner is set to 220V, the first preset percentage is 90%, and the second preset percentage is 110%. When the actual voltage is less than 198V, the power supply environment is level one; when the actual voltage is greater than or equal to 198V and less than or equal to 242V, the power supply level is level two; when the actual voltage is greater than 242V, the power supply level is level three.

[0072] In another specific embodiment, the outdoor ambient temperature can also be added as a weighting factor to a preset percentage of the rated voltage, thereby affecting the classification of power supply levels.

[0073] The first preset percentage when the current outdoor ambient temperature is not less than the first temperature threshold and not greater than the second temperature threshold is different from the first preset percentage when the current outdoor ambient temperature is less than the first temperature threshold or greater than the second temperature threshold.

[0074] The second preset percentage when the current outdoor ambient temperature is not less than the first temperature threshold and not greater than the second temperature threshold is different from the second preset percentage when the current outdoor ambient temperature is less than the first temperature threshold or greater than the second temperature threshold.

[0075] For example, a first temperature threshold is set to -4℃, and a second temperature threshold is set to 43℃. When the outdoor ambient temperature is greater than or equal to -4℃ and less than or equal to 43℃, 1% is added to the first and second preset percentages of the rated voltage; when the outdoor ambient temperature is less than -4℃ or greater than 43℃, 5% is added to the first and second preset percentages of the rated voltage. Similarly, when the outdoor ambient temperature is greater than or equal to -4℃ and less than or equal to 43℃, the first and second preset percentages of the rated voltage remain unchanged; when the outdoor ambient temperature is less than -4℃ or greater than 43℃, 5% is added to the first and second preset percentages of the rated voltage.

[0076] S2. Determine the current operating parameters of the air conditioner based on the current power environment level and the historical power environment level.

[0077] In one specific embodiment, determining the current operating parameters of the air conditioner based on the current power environment level and the historical power environment level includes:

[0078] When both the current power environment level and the historical power environment level are Level 1, the air conditioner operates at its rated power.

[0079] When the current power environment level is Level 1 but the historical power environment level is Level 2, the air conditioner operates at a first preset ratio of the rated power.

[0080] When the current power environment level is Level 1 but the historical power environment level is Level 3, the air conditioner operates at a second preset ratio of the rated power, wherein the second preset ratio ≤ the first preset ratio ≤ 1;

[0081] When the current power environment level is Level 2 and the historical power environment level is Level 1, the air conditioner operates at a third preset ratio of rated power.

[0082] When the current power environment level is Level 2 and the historical power environment level is Level 2, the air conditioner operates at the fourth preset ratio of rated power;

[0083] When the current power environment level is Level 2 and the historical power environment level is Level 3, the air conditioner operates at the fifth preset ratio of rated power, wherein the fifth preset ratio ≤ the fourth preset ratio ≤ the third preset ratio ≤ 1;

[0084] When the current power environment level is Level 3 and the historical power environment level is Level 1, the air conditioner operates at the sixth preset ratio of its rated power.

[0085] When the current power environment level is Level 3 and the historical power environment level is Level 2, the air conditioner operates at the seventh preset ratio of its rated power.

[0086] When the current power environment level is Level 3 and the historical power environment level is Level 3, the air conditioner operates at the eighth preset ratio of its rated power, wherein the eighth preset ratio < the seventh preset ratio ≤ the sixth preset ratio ≤ 1.

[0087] For example, as shown in Table 1, the rated power of the air conditioner is set to 800W, and the first to eighth preset ratios are 90%, 80%, 90%, 80%, 70%, 70%, 60%, and 50%, respectively. When both the current power level and the historical power level are at level one, the air conditioner operates at 800W; when the current power level is level one and the historical power level is level two, the air conditioner operates at 720W; when the current power level is level one and the historical power level is level three, the air conditioner operates at 640W, and so on.

[0088] Table 1

[0089]

[0090] It's important to note that in practical applications, if the performance requirements for air conditioning are relatively low, the air conditioner will operate at 100% rated power even when both the current and historical power supply levels are Level 1, the current power supply level is Level 1 and the historical power supply level is Level 2, and the current power supply level is Level 2 and the historical power supply level is Level 1, and so on. The only requirement is that the air conditioner's operating parameters are lower when both the current and historical power supply levels are Level 3 than in other cases. Similarly, the same approach can be used to determine the restart interval and the maximum number of restarts during a shutdown and restart cycle.

[0091] The current operating parameters of the air conditioner can be determined using the control method described above.

[0092] Furthermore, air conditioners may experience malfunctions and shutdowns during actual use, but there is currently no optimized solution for when they should restart. Therefore, the air conditioner control method in this embodiment of the invention further includes S3, such as... Figure 2 As shown: The restart interval time of the air conditioner when it is stopped and restarted is determined based on the current power environment level and the historical power environment level.

[0093] In one specific embodiment, determining the restart interval time of the air conditioner during shutdown and restart based on the current power environment level and the historical power environment level includes:

[0094] When both the current power environment level and the historical power environment level are at level one, the restart interval of the air conditioner is the first preset restart interval.

[0095] When the current power environment level is Level 1 but the historical power environment level is Level 2, the restart interval of the air conditioner is the second preset restart interval.

[0096] When the current power environment level is Level 1 but the historical power environment level is Level 3, the restart interval of the air conditioner is the third preset restart interval, wherein the first preset restart interval ≤ the second preset restart interval ≤ the third preset restart interval.

[0097] When the current power environment level is Level 2 and the historical power environment level is Level 1, the restart interval of the air conditioner is the fourth preset restart interval.

[0098] When the current power environment level is Level 2 and the historical power environment level is Level 2, the restart interval of the air conditioner is the fifth preset restart interval.

[0099] When the current power environment level is Level 2 and the historical power environment level is Level 3, the restart interval of the air conditioner is the sixth preset restart interval, wherein the fourth preset restart interval ≤ the fifth preset restart interval ≤ the sixth preset restart interval.

[0100] When the current power environment level is Level 3 and the historical power environment level is Level 1, the restart interval of the air conditioner is the seventh preset restart interval.

[0101] When the current power environment level is Level 3 and the historical power environment level is Level 2, the restart interval of the air conditioner is the eighth preset restart interval.

[0102] When the current power environment level is Level 3 and the historical power environment level is Level 3, the restart interval of the air conditioner is the ninth preset restart interval, wherein the seventh preset restart interval ≤ the eighth preset restart interval ≤ the ninth preset restart interval.

[0103] For example, as shown in Table 2, the first to ninth preset restart intervals are set to 3 min, 5 min, 10 min, 5 min, 5 min, 10 min, 10 min, 10 min, 10 min, 10 min, or 30 min (the first 10 restarts are 10 min apart, and the interval after a failure is 30 min). When both the current power level and the historical power level are at level one, the interval for the air conditioner to restart after a failure is 3 min; when the current power level is level one and the historical power level is level two, the interval for the air conditioner to restart after a failure is 5 min; when the current power level is level one and the historical power level is level three, the interval for the air conditioner to restart after a failure is 10 min, and so on.

[0104] Table 2

[0105]

[0106] It's important to note that when both the current and historical power ratings are at level three, the interval between air conditioner shutdowns and restarts after a malfunction is 10 minutes. If, after restarting and running for a period, the air conditioner shuts down again, and both the current and historical power ratings remain at level three, and this number of shutdowns reaches 10, it indicates a relatively poor power environment. In this case, the restart interval can be adjusted to 30 minutes. The purpose of this is to extend the restart time to rule out shutdowns caused by poor power conditions. If the air conditioner still shuts down after adjusting the restart time, then a malfunction is confirmed.

[0107] In addition, the air conditioning control method in this embodiment of the invention also includes a step of controlling the number of restarts, such as... Figure 3 As shown, it includes steps S4-S5.

[0108] S4. Determine the upper limit of the number of restarts of the air conditioner when it is stopped and restarted based on the current power environment level and the historical power environment level.

[0109] In one specific embodiment, determining the upper limit of the number of restarts of the air conditioner during shutdown and restart based on the current power environment level and the historical power environment level includes:

[0110] When both the current power environment level and the historical power environment level are at level one, the maximum number of times the air conditioner can be restarted is a first preset number.

[0111] When the current power environment level is Level 1 but the historical power environment level is Level 2, the maximum number of times the air conditioner can be restarted is a second preset number.

[0112] When the current power environment level is Level 1 but the historical power environment level is Level 3, the maximum number of times the air conditioner can be restarted is a third preset number, where the first preset number ≤ the second preset number ≤ the third preset number;

[0113] When the current power environment level is Level 2 and the historical power environment level is Level 1, the maximum number of times the air conditioner can be restarted is the fourth preset number of times.

[0114] When the current power environment level is Level 2 and the historical power environment level is Level 2, the maximum number of times the air conditioner can be restarted is the fifth preset number of times.

[0115] When the current power environment level is Level 2 and the historical power environment level is Level 3, the maximum number of times the air conditioner can be restarted is the sixth preset number, where the fourth preset number ≤ the fifth preset number ≤ the sixth preset number;

[0116] When the current power environment level is Level 3 and the historical power environment level is Level 1, the maximum number of times the air conditioner can be restarted is the seventh preset number of times.

[0117] When the current power environment level is Level 3 and the historical power environment level is Level 2, the maximum number of times the air conditioner can be restarted is the eighth preset number of times.

[0118] When the current power environment level is Level 3 and the historical power environment level is Level 3, the maximum number of restarts for the air conditioner is the ninth preset number, wherein the seventh preset number ≤ the eighth preset number < the ninth preset number, and the ninth preset restart interval before the number of restarts of the air conditioner reaches a preset proportion of the ninth preset number is less than the ninth preset restart interval after reaching the ninth preset number.

[0119] For example, as shown in Table 3, the first to ninth preset counts are set to 3, 5, 5, 3, 5, 10, 5, 10, and 11 times respectively. When both the current power level and the historical power level are at level one, the maximum number of restarts for the air conditioner after a fault shutdown is the first preset count of 3 times; when the current power level is level one and the historical power level is level two, the maximum number of restarts for the air conditioner after a fault shutdown is the second preset count of 5 times; when the current power level is level one and the historical power level is level three, the maximum number of restarts for the air conditioner after a fault shutdown is the third preset count of 5 times, and so on.

[0120] Table 3

[0121]

[0122] S5. If the number of restarts reaches the upper limit, it is determined that the air conditioner itself has malfunctioned.

[0123] It is important to note that when the air conditioner malfunctions and stops, both the current power level and the historical power level are at level three. It restarts according to the preset restart interval. If it malfunctions and stops again after running for a period of time, and both the current power level and the historical power level remain at level three, and the cumulative number of stops reaches 10 under these conditions, it means that the power environment in which the air conditioner is operating is relatively poor. In this case, the restart interval of the air conditioner can be adjusted. If the air conditioner still stops after adjustment (i.e., the number of stops reaches 11), then it is confirmed that the air conditioner does indeed have a malfunction.
