Some related technologies use a fixed value for frequency correction, while others adjust the frequency based on indoor ambient temperature and the internal coil temperature. The problem with these solutions is their inability to flexibly adapt to changes in operating conditions during heating.

[0031] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0032] When an air conditioner is running in heating mode, if the indoor fan speed is low while the compressor frequency is too high, the rapidly generated heat will concentrate in the indoor coil and cannot be released into the room in time by the indoor fan, potentially causing the indoor coil temperature to become too high. Excessive indoor coil temperature may trigger the air conditioner's frequency limiting or throttling mechanism, or even trigger a protective shutdown, leading to frequent changes in the compressor frequency.
[0033] Changes in compressor frequency lead to variations in system pressure, especially rapid changes, which can cause system pressure instability. Such pressure fluctuations can affect the heating performance of the air conditioner. Furthermore, frequent compressor frequency changes cause variations in the frequency of compressor exhaust pulsations, potentially causing vibration and noise in the piping. In particular, vibrations at specific frequencies may resonate with the natural frequency of the piping, exacerbating noise transmission problems. Therefore, this application provides an air conditioner operation control method that corrects the upper limit frequency of the compressor in heating mode, maximizing the air conditioner's heating effect while minimizing compressor frequency fluctuations and noise transmission issues.
[0034] Figure 1 A flowchart illustrating an air conditioner operation control method according to some embodiments of this application is shown. Although a logical sequence is shown in the flowchart, in some cases, the operations shown or described may be performed in a different order than that shown in the figures. Specifically, the specific flow of the method is as follows:
[0035] S101. Obtain the continuous running time of the air conditioner's compressor in heating mode.
[0036] To meet user comfort requirements, this method allows for a rapid rise in indoor temperature during the initial phase of heating mode activation by reducing restrictions on compressor frequency. After the initial phase, the compressor frequency upper limit is adjusted to achieve a smoother frequency transition.
[0037] The compressor's continuous operating time can be used to determine whether the air conditioner is in the initial stage after the heating mode is turned on. The compressor's continuous operating time is the time the compressor operates continuously after the heating mode is turned on. In some cases, the time when the heating mode is turned on is the same as the air conditioner's start-up time. In other cases, the time when the heating mode is turned on is later than the air conditioner's start-up time.
[0038] S103. When the continuous running time is less than or equal to the preset time, the frequency correction factor shall be determined at least based on the indoor coil temperature.
[0039] When the continuous operating time of the compressor is less than or equal to a preset time, the air conditioner is in the initial stage of heating mode operation. In the initial stage of heating mode, it is necessary to balance the heating rate (compressor frequency) and the indoor coil temperature to avoid excessively high indoor coil temperatures due to reduced restrictions on the compressor frequency. Therefore, this method determines the compressor frequency correction coefficient based at least on the indoor coil temperature.
[0040] The preset time can serve as a threshold for determining whether the air conditioner is in the initial stage after the heating mode has been activated. The preset time can be a fixed value or a modifiable value. For example, the preset time can be set internally by the air conditioner before it leaves the factory. Alternatively, the preset time can be set by the user via remote control or an app. Different air conditioner models can have different preset times, or they can have the same preset time. Air conditioners of the same model can have different preset times, or they can have the same preset time.
[0041] The preset time can be any value between 15 and 45 minutes. For example, the preset time can be 15 minutes, 20 minutes, 25 minutes, 30 minutes, 35 minutes, 40 minutes, 45 minutes, etc.
[0042] In heating mode, the indoor coil releases heat into the room. If the indoor coil's heat dissipation rate is low while the compressor frequency is high, the heat inside the indoor coil cannot be released in time. If the heat accumulates in the indoor coil, its temperature will rise. When the indoor coil temperature rises to a certain level, it may trigger a frequency reduction mechanism or shut down the unit. Therefore, even in the initial stage of heating mode, if the indoor coil temperature is too high, the compressor frequency still needs to be limited.
[0043] The frequency correction factor plays a regulatory role in adjusting the upper limit of the compressor's frequency. Under otherwise unchanged conditions, a larger frequency correction factor results in a greater adjustment range for the compressor's upper frequency limit.
[0044] S105. If the continuous running time is longer than the preset time, determine the frequency correction coefficient based on the outdoor ambient temperature.
[0045] If the compressor runs continuously for longer than the preset time, the air conditioner has passed the initial stage of heating mode, i.e., the stage requiring rapid heating has passed. At this point, the frequency correction factor is determined based on the outdoor ambient temperature, not the indoor coil temperature.
[0046] Outdoor ambient temperature can be used to determine the heating efficiency of an air conditioner. Theoretically, the higher the outdoor ambient temperature, the higher the heating efficiency of the air conditioner. Therefore, to achieve the same heating effect in the same amount of time, a higher outdoor ambient temperature requires a lower compressor frequency; conversely, a lower outdoor ambient temperature requires a higher compressor frequency. In other words, a higher outdoor ambient temperature allows for a larger adjustment to the upper limit of the compressor frequency; conversely, a lower outdoor ambient temperature requires a smaller adjustment.
[0047] Furthermore, the variation in outdoor ambient temperature is relatively small. For example, within a half-hour period, the change in outdoor ambient temperature is almost negligible, or in other words, the likelihood of significant fluctuations in outdoor ambient temperature within a short period is low. Therefore, using outdoor ambient temperature as the criterion for determining the frequency correction coefficient can prevent the frequency correction coefficient from changing frequently.
[0048] S107. Based on the frequency correction coefficient, determine the upper limit correction value of the compressor operating frequency.
[0049] The compressor operating frequency upper limit correction value is the result after correcting the upper frequency limit value. As mentioned earlier, under the premise that other conditions remain unchanged, the larger the frequency correction coefficient, the greater the magnitude of the correction to the compressor operating frequency upper limit.
[0050] In the method provided in this application embodiment, when the air conditioner operates continuously in heating mode for no more than a preset time, the indoor coil temperature is used as a priority condition to determine the frequency correction coefficient; after the continuous operating time exceeds the preset time, the frequency correction coefficient is determined based on the outdoor ambient temperature. This method can correct the upper limit frequency of the compressor based on different heating periods.
[0051] The following section describes how the frequency correction coefficient is determined within a preset time period.
[0052] As mentioned earlier, during the preset time of operation in heating mode, a frequency correction factor is determined at least based on the indoor coil temperature. In some embodiments, determining the frequency correction factor based at least on the indoor coil temperature may involve determining the frequency correction factor based on both the indoor coil temperature and the outdoor ambient temperature. During the preset time of operation in heating mode, it is necessary to balance the heating rate (compressor frequency) and the indoor coil temperature to avoid excessively high indoor coil temperatures due to reduced restrictions on the compressor frequency. Therefore, in some embodiments, when the indoor coil temperature is acceptable, the restriction on the compressor frequency is reduced; when the indoor coil temperature is too high, the restriction on the compressor frequency is strengthened in conjunction with the outdoor ambient temperature.
[0053] Figure 2 A flowchart illustrating the determination of frequency correction coefficients according to some embodiments of this application is shown. Although a logical sequence is shown in the flowchart, in some cases, the operations shown or described may be performed in a different order than that shown in the figures. The flow of operation S103 can be as follows: Figure 2 As shown:
[0054] S201, Obtain the indoor coil temperature.
[0055] S203. When the indoor coil temperature is less than the inner tube temperature threshold, the frequency correction factor is determined as the first correction factor.
[0056] When the indoor coil temperature is lower than the internal pipe temperature threshold, user comfort needs are prioritized, i.e., rapid heating is achieved, and there is no need to impose excessive restrictions on the compressor frequency. The internal pipe temperature threshold is the upper limit of the internal pipe temperature that the air conditioner can accept within a preset time period.
[0057] The first correction factor can make a small correction to the upper limit of the compressor frequency. In some embodiments, the value of the first correction factor can be zero, that is, keeping the upper limit of the compressor frequency unchanged.
[0058] S205. When the indoor coil temperature is greater than or equal to the indoor coil temperature threshold, the frequency correction coefficient shall be determined based on the outdoor ambient temperature.
[0059] If the indoor coil temperature is greater than or equal to the indoor coil temperature threshold, there may be a risk of overheating if the indoor coil temperature continues to rise. In this case, the frequency correction factor can be determined in conjunction with the outdoor ambient temperature to correct the upper limit of the frequency.
[0060] Figure 3 A flowchart illustrating the determination of frequency correction coefficients according to some embodiments of this application is shown. Although a logical sequence is shown in the flowchart, in some cases, the operations shown or described may be performed in a different order than that shown in the figures. The specific flow of operation S205 can be as follows: Figure 3 As shown:
[0061] S301, Obtain the outdoor ambient temperature.
[0062] As mentioned earlier, when the outdoor ambient temperature is low, the air conditioner's heating efficiency is lower, and the compressor frequency is higher than that required when the outdoor ambient temperature is higher. Therefore, the upper limit correction value for the compressor frequency when the outdoor ambient temperature is low can be higher than the upper limit correction value when the outdoor ambient temperature is high.
[0063] To maintain the stability of frequency correction and reduce large frequency fluctuations, the frequency correction coefficient can be set in zones based on the range of outdoor ambient temperature. This embodiment uses the division of outdoor ambient temperature into three zones as an example. It should be understood that other numbers of zones are also within the scope of protection of this application.
[0064] S303. When the outdoor ambient temperature is lower than the first outer ambient temperature, the frequency correction factor is determined to be the first correction factor.
[0065] S305. When the outdoor ambient temperature is greater than or equal to the first outer ambient temperature and less than the second outer ambient temperature, the frequency correction factor shall be determined as the second correction factor.
[0066] S307. When the outdoor ambient temperature is greater than or equal to the second ambient temperature, the frequency correction factor shall be determined as the third correction factor.
[0067] The first outer ring temperature and the second outer ring temperature can be used to divide the outdoor ambient temperature into three temperature ranges. The first outer ring temperature and the second outer ring temperature can be preset temperature values.
[0068] Among them, the first correction factor is less than the second correction factor, and the second correction factor is less than the third correction factor.
[0069] Table 1 shows a comparison table of how the frequency correction coefficient is determined within a preset time period in some embodiments of this application. Wherein, T... 内管 Indicates the indoor coil temperature, T 外环 The values represent the outdoor ambient temperature, A1 represents the first correction factor, A2 represents the second correction factor, and A3 represents the third correction factor. In the embodiment shown in Table 1, the inner pipe temperature threshold is 42℃, the first outer ambient temperature is -12℃, and the second outer ambient temperature is 0℃.
[0070] Table 1
[0071]
[0072] In some embodiments of this application, when determining the frequency correction coefficient within a preset time period, the indoor coil temperature condition can be assessed first. When the indoor coil temperature is within a threshold range, the heating effect is prioritized, and a lower frequency correction coefficient is determined. When the indoor coil temperature exceeds the threshold, the frequency correction coefficient is determined in conjunction with the outdoor ambient temperature. Therefore, the control method provided by some embodiments of this application can guarantee the heating effect within a preset time period and can also correct the frequency in a timely manner.
[0073] The following section describes how the frequency correction factor is determined after a preset time.
[0074] Figure 4 A flowchart illustrating the determination of frequency correction coefficients according to some embodiments of this application is shown. Although a logical sequence is shown in the flowchart, in some cases, the operations shown or described may be performed in a different order than that shown in the figures. The flow of operation S105 can be as follows: Figure 4 As shown:
[0075] S401, Obtain the outdoor ambient temperature.
[0076] As mentioned earlier, the frequency correction coefficient can be set in zones based on the outdoor ambient temperature range. This embodiment uses dividing the outdoor ambient temperature into three zones as an example; it is understood that other numbers of zones are also within the scope of this application. Furthermore, the zoning method for the outdoor ambient temperature after a preset time can be the same as or different from that within the preset time period.
[0077] S403. When the outdoor ambient temperature is lower than the first outer ambient temperature, the frequency correction factor is determined to be the first correction factor.
[0078] S405. When the outdoor ambient temperature is greater than or equal to the first outer ambient temperature and less than the second outer ambient temperature, the frequency correction factor shall be determined as the fourth correction factor.
[0079] S407. When the outdoor ambient temperature is greater than or equal to the second outer ambient temperature, the frequency correction factor shall be determined as the fifth correction factor.
[0080] The first outer ring temperature and the second outer ring temperature can be used to divide the outdoor ambient temperature into three temperature ranges. The first outer ring temperature and the second outer ring temperature can be preset temperature values.
[0081] Among them, the first correction factor is less than the fourth correction factor, and the fourth correction factor is less than the fifth correction factor.
[0082] After a preset time, the demand for rapid heating decreases, at which point the upper limit of the frequency can be adjusted more significantly. In some embodiments, the fourth adjustment value can be greater than the second adjustment value, and the fifth adjustment value can be greater than the third adjustment value.
[0083] Table 2 shows a comparison table of how the frequency correction coefficient is determined after a preset time in some embodiments of this application. Wherein, T... 内管 Indicates the indoor coil temperature, T 外环 The values represent the outdoor ambient temperature, A1 represents the first correction factor, A4 represents the fourth correction factor, and A5 represents the fifth correction factor. In the embodiment shown in Table 1, the inner pipe temperature threshold is 42℃, the first outer ambient temperature is -12℃, and the second outer ambient temperature is 0℃.

[0085] Outdoor ambient temperature conditions Frequency correction factor <![CDATA[T 外环 <-12℃]]> A1 <![CDATA[-12℃≤T 外环 <0℃]]> A4 <![CDATA[0℃≤T 外环 ]]> A5
[0086] In some embodiments of this application, the frequency correction factor is determined by considering the outdoor ambient temperature after a preset time. Therefore, the control method provided by some embodiments of this application can promptly correct the frequency after the preset time is reached, and frequent frequency fluctuations are less likely to occur.
[0087] The preceding text described in detail how to determine the frequency correction factor within and after the preset time. The following text will describe how to determine the upper limit correction value for compressor operation based on the frequency correction factor.
[0088] Figure 5A flowchart illustrating the determination of a frequency upper limit correction value is shown, according to some embodiments of this application. Although a logical sequence is shown in the flowchart, in some cases, the operations shown or described may be performed in a different order than those shown in the figures. The flow of operation S107 can be as follows: Figure 5 As shown:
[0089] S501. Obtain the fan speed setting of the indoor fan of the air conditioner.
[0090] The fan speed setting reflects the rotational speed of the indoor fan. There is a negative correlation between the fan speed setting and the indoor fan speed; that is, the higher the fan speed setting, the lower the indoor fan speed, and vice versa.
[0091] S503, Obtain the upper limit value of compressor frequency corresponding to the outdoor ambient temperature.
[0092] The compressor frequency limit is the maximum frequency at which the compressor can operate under different outdoor ambient temperatures in the default state.
[0093] S505. Determine the upper frequency limit correction value based on the upper frequency limit, wind speed setting, and frequency correction coefficient.
[0094] As mentioned earlier, in heating mode, if the indoor fan speed is low (the fan speed setting is high) while the compressor operates at a high frequency, it may cause the system to overheat, leading to frequency fluctuations and conduction noise due to frequent frequency throttling. Therefore, some embodiments of this application can adjust the upper frequency limit based on the fan speed setting. When the indoor fan speed is low, i.e., the fan speed setting is high, the frequency is adjusted more significantly; conversely, the adjustment is smaller. The adjustment magnitude can be reflected by the difference between the upper frequency limit value and the adjusted upper frequency limit value. The difference between the upper frequency limit value and the adjusted upper frequency limit value is negatively correlated with the fan speed setting.
[0095] In some embodiments, the frequency upper limit correction value in operation S505 can be determined as follows:
[0096] F 上限修正 =F 上限 -A×B
[0097] Among them, F 上限修正 F represents the upper limit correction value for frequency. 上限 The upper frequency limit is represented by F, where A represents the frequency correction factor and B represents the wind speed setting. 上限 It is negatively correlated with outdoor ambient temperature. The higher the outdoor ambient temperature, the higher the corresponding upper limit of frequency F. 上限 The higher the outdoor ambient temperature, the lower the corresponding upper frequency limit F; conversely, the lower the outdoor ambient temperature, the higher the corresponding upper frequency limit F. 上限 The higher the value, the better.
[0098] Therefore, all other things being equal, the higher the outdoor ambient temperature, the higher the frequency upper limit correction value F. 上限修正 The lower the outdoor ambient temperature, the higher the frequency upper limit correction value F; conversely, the lower the outdoor ambient temperature, the higher the frequency upper limit correction value F. 上限修正 The higher the outdoor temperature, the higher the compressor's heating efficiency, allowing it to operate at a lower frequency. Under otherwise identical conditions, the higher the fan speed setting B (lower indoor fan speed), the higher the frequency upper limit correction value F. 上限修正 The lower the value of the wind speed setting B (the higher the internal fan speed), the lower the frequency upper limit correction value F. 上限修正 The higher the temperature, the better. In other words, when the indoor fan speed is low, in order to prevent the indoor coil from overheating due to the inability to dissipate heat quickly, the compressor operating frequency can be appropriately reduced.
[0099] The frequency correction factor A can be determined using the method described above. For example, frequency correction factor A can be A1, A2, A3, A4, or A5. The fan speed setting B can be a preset value in the air conditioner; different fan speed settings correspond to different indoor fan speeds. The smaller the value of fan speed setting B, the higher the indoor fan speed.
[0100] In some embodiments, the first frequency correction factor A1 can be equal to 0. The second frequency correction factor A2 can be equal to 2. The third frequency correction factor A3 can be equal to 4. The fourth frequency correction factor A4 can be equal to 3. The fifth frequency correction factor A5 can be equal to 5.
[0101] In some embodiments, the fan speed setting B corresponding to the highest speed of the indoor fan is equal to 0. The fan speed setting B corresponding to the second speed of the indoor fan is equal to 1. The fan speed setting B corresponding to the third speed of the indoor fan is equal to 2. And so on, the air conditioner may include more fan speed settings.
[0102] Figure 6 Example diagrams of an air conditioner operation control method provided in some embodiments of this application are shown. Although a logical sequence is shown in the flowcharts, in some cases, the operations shown or described may be performed in a different order than that shown in the figures.
[0103] like Figure 6 As shown in this embodiment, in the method provided, after the air conditioner enters the heating mode, the continuous running time of the compressor is obtained. Then, it is determined whether the continuous running time is greater than a preset time.
[0104] If within the preset time, the indoor coil temperature is acquired, and it is determined whether the indoor coil temperature is lower than the inner pipe temperature threshold. If the indoor coil temperature is lower than the inner pipe temperature threshold, the frequency correction factor is set as the first correction factor. If the indoor coil temperature is greater than or equal to the inner pipe temperature threshold, the frequency correction factor is further determined based on the outdoor ambient temperature. For instructions on how to determine the frequency correction factor based on the outdoor ambient temperature, please refer to [link to relevant documentation]. Figure 6 as well as Figure 3 The details of the description will not be repeated here.
[0105] If the preset time has elapsed, the frequency correction factor is determined based on the outdoor ambient temperature. For instructions on how to determine the frequency correction factor based on the outdoor ambient temperature, please refer to [link to relevant documentation]. Figure 6 as well as Figure 4 The details of the description will not be repeated here.
[0106] After determining the frequency correction factor, obtain the upper limit of the compressor frequency corresponding to the fan speed setting of the indoor fan and the outdoor ambient temperature. Based on the upper limit of the frequency, the fan speed setting, and the frequency correction factor, determine the upper limit frequency correction value.
[0107] In summary, the air conditioner operation control method provided in this application embodiment can achieve rapid heating in the initial stage of heating and can adjust the frequency in a timely manner. Determining the frequency correction coefficient based on the outdoor ambient temperature can minimize frequent changes in the compressor frequency and reduce noise transmission issues.
[0108] Figure 7 The diagram shows a schematic representation of a control device provided in some embodiments of this application. Specifically, the control device 600 may include:
[0109] The acquisition module 601 is used to acquire the continuous running time of the air conditioner's compressor in heating mode.
[0110] The first determining module 603 is used to determine the frequency correction coefficient based at least on the indoor coil temperature when the continuous running time is less than or equal to a preset time, or based on the outdoor ambient temperature when the continuous running time is greater than the preset time.
[0111] The second determining module 605 is used to determine the upper limit correction value of the compressor's operating frequency based on the frequency correction coefficient.
[0112] In some embodiments of this application, the control device 600 acquires the continuous operating time of the compressor via an acquisition module 601 after the air conditioner enters heating mode. A first determining module 603 determines a frequency correction coefficient based at least on the indoor coil temperature if the continuous operating time is less than or equal to a preset time; or, if the continuous operating time is greater than the preset time, it determines a frequency correction coefficient based on the outdoor ambient temperature. Subsequently, a second determining module 605 determines an upper frequency correction value for the compressor based on the frequency correction coefficient.
[0113] In some embodiments, the first determining module 603 may include a first acquiring unit and a first determining unit. The first acquiring unit may be used to acquire the indoor coil temperature. The first determining unit may be used to determine a frequency correction coefficient as a first correction coefficient when the indoor coil temperature is less than the inner tube temperature threshold, or to determine a frequency correction coefficient based on the outdoor ambient temperature when the indoor coil temperature is greater than or equal to the inner tube temperature threshold.
[0114] In some embodiments, the first determining unit may include a first acquiring subunit and a first determining subunit.
