Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0029] Figure 1 This is a flowchart of an air conditioner operation control method according to an embodiment of this application. Figure 1 As shown, the method includes the following steps:
[0030] Step S201: Obtain the operating parameters of the air conditioner, wherein the operating parameters include at least one of the three-phase current of the air conditioner's compressor, the power of the compressor, and the discharge temperature of the compressor.
[0031] Specifically, to address the problem that air conditioners are prone to abnormal shutdowns in complex working environments, the following measures are taken: First, the probability of air conditioner shutdown can be determined based on the air conditioner's operating parameters. In some implementations, the probability of air conditioner shutdown is higher when the three-phase current of the air conditioner compressor is low or high; the probability of air conditioner shutdown is higher when the compressor power is low or high; and the probability of air conditioner shutdown is higher when the compressor exhaust temperature is low or high. The probability of air conditioner shutdown can be accurately determined based on multiple operating parameters of the air conditioner.
[0032] Step S202: Adjust the frequency of the compressor using the operating parameters of the air conditioner to make the frequency of the compressor within a preset frequency range, thereby reducing the probability of abnormal shutdown of the air conditioner.
[0033] Specifically, the probability of air conditioner shutdown is determined based on the air conditioner's operating parameters. Based on this probability, precise protection control of the compressor frequency is implemented to ensure stable operation of the air conditioner and effectively prevent abnormal shutdowns. This addresses the problem in existing technologies where air conditioners are prone to abnormal shutdowns in complex working environments.
[0034] The above step S202 can be implemented as follows:
[0035] Step S2021: When at least one of the above operating parameters is within the first preset operating parameter range, increase the frequency of the compressor so that the frequency of the compressor is within the preset frequency range, wherein the above operating parameters correspond one-to-one with the first preset operating parameter range.
[0036] The above step S2021 can be implemented as follows:
[0037] When at least one of the above operating parameters is within the range of the first preset operating parameters, the frequency of the compressor is increased by a preset frequency ramp rate so that the frequency of the compressor is within the preset frequency range.
[0038] In this embodiment, when the value of at least one operating parameter is within the first preset operating parameter range, it indicates that the operating parameter of the air conditioner compressor is relatively small, and the probability of the air conditioner stopping is relatively high. At this time, the frequency of the compressor is increased by a preset frequency ramp rate to increase the value of the operating parameter, and to ensure that the frequency of the compressor does not exceed the maximum value of the preset frequency range, so as to achieve stable adjustment of the compressor frequency and avoid the phenomenon of abnormal air conditioner stopping.
[0039] The above step S2021 can be implemented as follows:
[0040] Determine whether the three-phase current of the compressor satisfies the first condition C2 < C1 ≤ C3, determine whether the power of the compressor satisfies the second condition P2 < P1 ≤ P3, and determine whether the exhaust temperature of the compressor satisfies the third condition T2 < T1 ≤ T3, where C1 represents the three-phase current of the compressor, P1 represents the power of the compressor, T1 represents the exhaust temperature of the compressor, C3 represents the maximum value of the first preset operating parameter range corresponding to the three-phase current of the compressor, P3 represents the maximum value of the first preset operating parameter range corresponding to the power of the compressor, and T3 represents the maximum value of the first preset operating parameter range corresponding to the exhaust temperature of the compressor;
[0041] When at least one of the following conditions is satisfied: the three-phase current of the compressor satisfies the first condition, the power of the compressor satisfies the second condition, and the exhaust temperature of the compressor satisfies the third condition, increase the frequency of the compressor so that the frequency of the compressor is within the preset frequency range;
[0042] In this embodiment, when the three-phase current of the compressor satisfies the first condition, it means that the three-phase current of the compressor of the air conditioner is small and the probability of the air conditioner stopping is large. When the power of the compressor satisfies the second condition, it means that the power of the compressor of the air conditioner is small and the probability of the air conditioner stopping is large. When the exhaust temperature of the compressor satisfies the third condition, it means that the exhaust temperature of the compressor is small and the probability of the air conditioner stopping is large. When at least one of the following conditions is satisfied: the three-phase current of the compressor satisfies the first condition, the power of the compressor satisfies the second condition, and the exhaust temperature of the compressor satisfies the third condition, it is determined that the probability of the air conditioner stopping is large. At this time, increase the frequency of the compressor to increase the parameter value of the operating parameter, thereby avoiding the phenomenon of abnormal shutdown of the air conditioner.
[0043] Step S2022: When the parameter value of at least one of the above operating parameters is within the second preset operating parameter range, reduce the frequency of the compressor so that the frequency of the compressor is within the preset frequency range, where the above operating parameters correspond one-to-one with the second preset operating parameter range, the first preset operating parameter range corresponds one-to-one with the second preset operating parameter range, and the maximum value of any one of the first preset operating parameter ranges is less than the minimum value of the second preset operating parameter range corresponding thereto;
[0044] The above step S2022 can be implemented as:
[0045] When the parameter value of at least one of the above operating parameters is within the second preset operating parameter range, reduce the frequency of the compressor at a preset frequency reduction rate so that the frequency of the compressor is within the preset frequency range.
[0046] In this embodiment, when the parameter values of at least one operating parameter are within the second preset operating parameter range, it indicates that the operating parameter of the compressor of the air conditioner is relatively large, and the probability of determining that the air conditioner stops is relatively large. At this time, at a preset frequency reduction rate, the frequency of the compressor is reduced to reduce the parameter value of the operating parameter, and moreover, it is ensured that the frequency of the compressor does not exceed the minimum value of the preset frequency range, so as to stably adjust the frequency of the compressor and avoid the phenomenon of abnormal shutdown of the air conditioner.
[0047] The above step S2022 can be implemented as follows:
[0048] Determine whether the three-phase current of the above compressor satisfies the fourth condition C4 < C1 ≤ C5, determine whether the power of the above compressor satisfies the fifth condition P4 < P1 ≤ P5, and determine whether the exhaust temperature of the above compressor satisfies the sixth condition T4 < T1 ≤ T5. Here, C4 represents the maximum value of the above third preset operating parameter range corresponding to the three-phase current of the above compressor, C5 represents the maximum value of the above second preset operating parameter range corresponding to the three-phase current of the above compressor, P4 represents the maximum value of the above third preset operating parameter range corresponding to the power of the above compressor, P5 represents the maximum value of the above second preset operating parameter range corresponding to the power of the above compressor, T4 represents the maximum value of the above third preset operating parameter range corresponding to the exhaust temperature of the above compressor, and T5 represents the maximum value of the above second preset operating parameter range corresponding to the exhaust temperature of the above compressor;
[0049] When at least one of the above three-phase current of the above compressor satisfies the above fourth condition, the above power of the above compressor satisfies the above fifth condition, and the above exhaust temperature of the above compressor satisfies the above sixth condition holds, reduce the frequency of the above compressor so that the frequency of the above compressor is within the above preset frequency range;
[0050] In this embodiment, that the three-phase current of the compressor satisfies the fourth condition indicates that the three-phase current of the compressor of the air conditioner is relatively large and the probability of the air conditioner stopping is relatively large. That the power of the compressor satisfies the fifth condition indicates that the power of the compressor of the air conditioner is relatively large and the probability of the air conditioner stopping is relatively large. That the power of the compressor satisfies the sixth condition indicates that the exhaust temperature of the compressor of the air conditioner is relatively large and the probability of the air conditioner stopping is relatively large. When at least one of the three-phase current of the compressor satisfies the fourth condition, the power of the compressor satisfies the fifth condition, and the exhaust temperature of the compressor satisfies the sixth condition holds, it is determined that the probability of the air conditioner stopping is relatively large. At this time, the frequency of the compressor is reduced to reduce the parameter value of the operating parameter, thus avoiding the phenomenon of abnormal shutdown of the air conditioner.
[0051] Step S2023, when the parameter values of at least one of the above operating parameters are within the third preset operating parameter range, keep the frequency of the above compressor unchanged, where the above operating parameters correspond one-to-one with the above third preset operating parameter range, the above third preset operating parameter range corresponds one-to-one with the above second preset operating parameter range, the maximum value of any of the above third preset operating parameter ranges is less than the minimum value of the corresponding above second preset operating parameter range, and the minimum value of any of the above third preset operating parameter ranges is greater than the maximum value of the corresponding above first preset operating parameter range.
[0052] The above step S2023 can be implemented as:
[0053] Determine whether the three-phase current of the above compressor satisfies the seventh condition C3 < C1 ≤ C4, determine whether the power of the above compressor satisfies the eighth condition P3 < P1 ≤ P4, and determine whether the exhaust temperature of the above compressor satisfies the ninth condition T3 < T1 ≤ T4;
[0054] When at least one of the three-phase current of the above compressor satisfies the above seventh condition, the power of the above compressor satisfies the above eighth condition, and the exhaust temperature of the above compressor satisfies the above ninth condition holds, keep the frequency of the above compressor unchanged.
[0055] In this embodiment, the three-phase current of the compressor satisfies the seventh condition, indicating that the three-phase current of the compressor of the air conditioner is normal, the probability of the air conditioner stopping is normal, the power of the compressor satisfies the eighth condition, indicating that the power of the compressor of the air conditioner is normal, the probability of the air conditioner stopping is normal, and the power of the compressor satisfies the ninth condition, indicating that the exhaust temperature of the compressor of the air conditioner is normal, the probability of the air conditioner stopping is normal. When at least one of the three-phase current of the compressor satisfies the seventh condition, the power of the compressor satisfies the eighth condition, and the exhaust temperature of the compressor satisfies the ninth condition holds, it is determined that the probability of the air conditioner stopping is normal. At this time, keep the frequency of the compressor unchanged to avoid the parameter values of the operating parameters from continuing to increase or decrease, thus avoiding the phenomenon of abnormal shutdown of the air conditioner.
[0056] In this embodiment, if the value of at least one operating parameter is within the first preset operating parameter range, it indicates that the compressor's operating parameter is relatively small, and the probability of the air conditioner stopping is relatively high. In this case, the frequency of the compressor is increased to increase the operating parameter, thereby preventing the abnormal shutdown of the air conditioner. If the value of at least one operating parameter is within the second preset operating parameter range, it indicates that the compressor's operating parameter is relatively large, and the probability of the air conditioner stopping is relatively high. In this case, the frequency of the compressor is decreased to decrease the operating parameter, thereby preventing the abnormal shutdown of the air conditioner. If the value of at least one operating parameter is within the third preset operating parameter range, it indicates that the operating parameter value is relatively small, and the probability of the air conditioner stopping is relatively small. The compressor frequency is kept constant to prevent the operating parameter value from continuing to increase or decrease, thereby preventing the abnormal shutdown of the air conditioner.
[0057] The above methods also include:
[0058] Step S301: When at least one of the above operating parameters is within the range of the fourth preset operating parameters, the frequency of the compressor is adjusted by the indoor ambient temperature and the outdoor ambient temperature. The above operating parameters correspond one-to-one with the above fourth preset operating parameter range, and the above fourth preset operating parameter range corresponds one-to-one with the above first preset operating parameter range. The maximum value of any of the above fourth preset operating parameter ranges is less than the minimum value of the above first preset operating parameter range corresponding to it.
[0059] In this embodiment, when the value of at least one operating parameter is within the range of the fourth preset operating parameter, the probability of the air conditioner stopping is very small. At this time, the frequency of the compressor is adjusted by the indoor ambient temperature and the outdoor ambient temperature.
[0060] The above step S301 can be implemented as follows:
[0061] Determine whether the three-phase current of the compressor satisfies the tenth condition C1≤C2, whether the power of the compressor satisfies the eleventh condition P1≤P2, and whether the exhaust temperature of the compressor satisfies the twelfth condition T1≤T2. C2 represents the maximum value of the fourth preset operating parameter range corresponding to the three-phase current of the compressor, P2 represents the maximum value of the fourth preset operating parameter range corresponding to the power of the compressor, and T2 represents the maximum value of the fourth preset operating parameter range corresponding to the exhaust temperature of the compressor.
[0062] If at least one of the following conditions is met: the three-phase current of the compressor meets the tenth condition, the power of the compressor meets the eleventh condition, and the exhaust temperature of the compressor meets the twelfth condition, the frequency of the compressor is adjusted by using the indoor ambient temperature and the outdoor ambient temperature.
[0063] In this embodiment, the three-phase current of the compressor satisfies the tenth condition, indicating that the three-phase current of the compressor of the air conditioner is very small, and the probability of the air conditioner shutting down is very small. The power of the compressor satisfies the eleventh condition, indicating that the power of the compressor of the air conditioner is very small, and the probability of the air conditioner shutting down is very small. The power of the compressor satisfies the twelfth condition, indicating that the exhaust temperature of the compressor of the air conditioner is very small, and the probability of the air conditioner shutting down is very small. When at least one of the three-phase current of the compressor satisfying the seventh condition, the power of the compressor satisfying the eighth condition, and the exhaust temperature of the compressor satisfying the ninth condition holds, it is determined that the probability of the air conditioner shutting down is very small. At this time, the frequency of the above compressor is adjusted according to the indoor ambient temperature and the outdoor ambient temperature, that is, the frequency of the compressor is determined to increase or decrease according to the indoor ambient temperature and the outdoor ambient temperature.
[0064] The above method further includes:
[0065] Step S302, when the parameter values of at least one of the above operating parameters are within the fifth preset operating parameter range, control the above compressor to shut down, where the above operating parameters correspond one-to-one to the fifth preset operating parameter range, the fifth preset operating parameter range corresponds one-to-one to the second preset operating parameter range, and the minimum value of any one of the fifth preset operating parameter ranges is greater than the maximum value of the corresponding second preset operating parameter range.
[0066] In this embodiment, when the parameter values of at least one operating parameter are within the fourth preset operating parameter range, it is determined that continuing to operate the air conditioner will damage the components inside the air conditioner. Therefore, the compressor is controlled to shut down to avoid damaging the air conditioner.
[0067] The above step S302 can be implemented as:
[0068] Determine whether the three-phase current of the above compressor satisfies the thirteenth condition C5 < C1, determine whether the power of the above compressor satisfies the fourteenth condition P5 < P1, and determine whether the exhaust temperature of the above compressor satisfies the fifteenth condition T5 < P1;
[0069] When at least one of the three-phase current of the above compressor satisfying the above thirteenth condition, the power of the above compressor satisfying the above fourteenth condition, and the exhaust temperature of the above compressor satisfying the above fifteenth condition holds, control the above compressor to shut down.
[0070] In this embodiment, the three-phase current of the compressor satisfies the eleventh condition, indicating that the three-phase current of the compressor of the air conditioner is very large and the probability of the air conditioner shutting down is very high. The power of the compressor satisfies the twelfth condition, indicating that the power of the compressor of the air conditioner is very large and the probability of the air conditioner shutting down is very high. The power of the compressor satisfies the thirteenth condition, indicating that the exhaust temperature of the compressor of the air conditioner is very large and the probability of the air conditioner shutting down is very high. When at least one of the three-phase current of the compressor satisfying the eleventh condition, the power of the compressor satisfying the twelfth condition, and the exhaust temperature of the compressor satisfying the thirteenth condition holds, it is determined that continuing to operate the air conditioner at this time will damage the components inside the air conditioner. Therefore, the compressor is controlled to shut down to avoid damaging the air conditioner.
[0071] Through the above embodiments, the probability of the air conditioner shutting down is determined according to the operating parameters of the air conditioner, and precise protection control of the frequency of the compressor is performed according to the determined probability of the air conditioner shutting down, ensuring the stable operation of the air conditioner and effectively avoiding the occurrence of abnormal shutdown of the air conditioner, solving the problem that the air conditioner is prone to abnormal shutdown in the prior art when the working environment of the air conditioner is relatively complex.

[0128] In this embodiment, when the value of at least one operating parameter is within the range of the fourth preset operating parameter, the probability of the air conditioner stopping is very small. At this time, the frequency of the compressor is adjusted by the indoor ambient temperature and the outdoor ambient temperature.
[0129] The aforementioned second adjustment unit includes a first determining module and a fourth adjustment module.

When the power of the compressor satisfies the twelfth condition, it means that the power of the compressor in the air conditioner is very large and the probability of the air conditioner stopping is very high. When the power of the compressor satisfies the thirteenth condition, it means that the exhaust temperature of the compressor in the air conditioner is very large and the probability of the air conditioner stopping is very high. When at least one of the following conditions is met: the three-phase current of the compressor satisfies the eleventh condition, the power of the compressor satisfies the twelfth condition, and the exhaust temperature of the compressor satisfies the thirteenth condition, it is determined that continuing to operate the air conditioner at this time will damage the components inside the air conditioner.
