[0031] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0032] When the air conditioner is running in heating mode, if the speed of the indoor fan is low and the frequency of the compressor is too high, the heat generated quickly is concentrated in the indoor coil and cannot be released to the room in time through the blowing of the indoor fan, which may cause the indoor coil temperature to be too high. If the indoor coil temperature is too high, it may trigger the frequency limiting or frequency reduction mechanism of the air conditioner, or even trigger a protection shutdown, causing the compressor frequency to change frequently.

[0033] Changes in the compressor frequency will cause changes in the system pressure, especially when it changes rapidly, which may cause instability in the system pressure. This pressure fluctuation may affect the heating effect of the air conditioner. In addition, the frequently changing compressor frequency will cause changes in the frequency of the compressor exhaust pulsation, which may cause vibration and noise in the pipeline, especially the vibration at a specific frequency may resonate with the natural frequency of the pipeline, resulting in an aggravation of the transmission sound problem. Therefore, an embodiment of the present application provides an operation control method for an air conditioner, which corrects the upper limit frequency of the compressor in the heating mode, so that the air conditioner can exert the heating effect as much as possible, and is not prone to compressor frequency fluctuations and transmission sound problems.

[0034] Figure 1 The flowchart of the operation control method of the air conditioner provided by some embodiments of the present application is shown. Although the logical order 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 drawings. Specifically, the specific process of the method is as follows:

[0035] S101. Obtain the continuous operation time of the compressor of the air conditioner in the heating mode.

[0036] In order to meet the user's comfort requirements, in the initial stage of the heating mode, the method can reduce the limit on the compressor frequency to make the indoor temperature rise quickly. After the initial stage, the compressor frequency upper limit is corrected to achieve a smooth change of the compressor frequency.

[0037] The continuous operation time of the compressor can be used to determine whether the air conditioner is in the initial stage after the heating mode is turned on. The continuous operation time of the compressor is the continuous working time of the compressor after the heating mode is turned on. In some cases, the time when the heating mode is turned on is the start-up time of the air conditioner. In some cases, the time when the heating mode is turned on is later than the start-up time of the air conditioner.

[0038] S103: When the continuous operation time is less than or equal to the preset time, determine a frequency correction coefficient at least according to the indoor coil temperature.

[0039] When the continuous operation time of the compressor is less than or equal to the preset time, the air conditioner is in the initial stage of the heating mode operation. In the initial stage of the heating mode, it is necessary to balance the heating speed (compressor frequency) and the indoor coil temperature to avoid excessive indoor coil temperature due to reducing the limit on the compressor frequency. Therefore, the method determines the frequency correction coefficient of the compressor at least according to the indoor coil temperature.

[0040] Among them, the preset time can be used as a threshold for determining whether the air conditioner is in the initial stage after the heating mode is turned on. The preset time can be a fixed value or a modifiable value. For example, the preset time can be set inside the air conditioner before leaving the factory. For example, the preset time can be set by the user through a remote control or an APP. Different models of air conditioners can be set with different preset times, or they can be set with the same preset time. The same model of air conditioners can be set with different preset times, or they can be set with the same preset time.

[0041] The preset time may be any time value between 15 minutes and 45 minutes. For example, the preset time may be 15 minutes, 20 minutes, 25 minutes, 30 minutes, 35 minutes, 40 minutes, 45 minutes, and the like.

[0042] Among them, the indoor coil releases heat to the room in the heating mode. When the heat dissipation rate of the indoor coil is low and the frequency of the compressor is high, the heat in the indoor coil cannot be released in time. If the heat in the indoor coil continues to accumulate, it will cause its temperature to rise. When the temperature of the indoor coil rises to a certain level, it may trigger the frequency reduction mechanism or shut down. Therefore, even if the air conditioner is in the initial stage of heating mode, when the indoor coil temperature is too high, the frequency of the compressor still needs to be limited.

[0043] The frequency correction coefficient can play a regulatory role in the correction of the frequency upper limit of the compressor. Under the premise that other conditions remain unchanged, the larger the frequency correction coefficient is, the greater the adjustment range of the compressor frequency upper limit is.

[0044] S105. When the continuous operation time is greater than a preset time, determine a frequency correction coefficient according to the outdoor ambient temperature.

[0045] When the continuous operation time of the compressor is greater than the preset time, the air conditioner has passed the initial stage of the heating mode, that is, the stage where rapid heating is required. At this time, the frequency correction coefficient does not need to be determined based on the indoor coil temperature, but is determined based on the outdoor ambient temperature.

[0046] Among them, the outdoor ambient temperature can be used to determine the heating efficiency of the air conditioner. When the outdoor ambient temperature is higher, the heating efficiency of the air conditioner will be higher in theory. Therefore, in the case of achieving the same heating effect in the same time, the higher the outdoor ambient temperature, the lower the required compressor frequency can be; conversely, the lower the outdoor ambient temperature, the higher the required compressor frequency. In other words, the higher the outdoor ambient temperature, the greater the correction amplitude of the compressor frequency upper limit can be; conversely, the lower the outdoor ambient temperature, the smaller the correction amplitude of the compressor frequency upper limit.

[0047] In addition, the change range of outdoor ambient temperature is small. For example, in a half-hour period, the change of outdoor ambient temperature is almost negligible, or in other words, the possibility of large fluctuation of outdoor ambient temperature in a short period of time is small. Therefore, using outdoor ambient temperature as a judgment condition for determining the frequency correction coefficient can make the frequency correction coefficient less likely to change frequently.

[0048] S107: Determine an upper frequency correction value of the compressor operation based on the frequency correction coefficient.

[0049] The upper frequency limit correction value of the compressor operation is the result of correcting the upper frequency limit value. As mentioned above, under the premise that other conditions remain unchanged, the larger the frequency correction coefficient is, the larger the amplitude of the upper frequency limit correction of the compressor operation is.

[0050] In the method provided in the embodiment of the present application, when the continuous working time of the air conditioner in the heating mode does not exceed the preset time, the frequency correction coefficient is determined based on the indoor coil temperature as a priority condition; after the continuous working 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 time periods.

[0051] The following describes how to determine the frequency correction coefficient within the preset time.

[0052] As mentioned above, during the preset time of the heating mode operation, the frequency correction coefficient is determined at least according to the indoor coil temperature. In some embodiments, the frequency correction coefficient is determined at least according to the indoor coil temperature, and the frequency correction coefficient may be determined jointly according to the indoor coil temperature and the outdoor ambient temperature. During the preset time of the heating mode operation, it is necessary to balance the heating speed (compressor frequency) and the indoor coil temperature to avoid excessive indoor coil temperature due to reducing the limit on the compressor frequency. Therefore, in some embodiments, when the indoor coil temperature is acceptable, the limit on the compressor frequency is reduced; when the indoor coil temperature is too high, the limit on the compressor frequency is strengthened in combination with the outdoor ambient temperature.

[0053] Figure 2 FIG. 1 is a flow chart of determining a frequency correction coefficient according to some embodiments of the present application. Although a logical sequence is shown in the flow chart, in some cases, the operations shown or described may be performed in a different order than that shown in the drawings. The process of operation S103 may be as follows: Figure 2 As shown:

[0054] S201. Obtain indoor coil temperature.

[0055] S203: When the indoor coil temperature is less than the internal tube temperature threshold, determine the frequency correction coefficient as the first correction coefficient.

[0056] When the indoor coil temperature is lower than the inner tube temperature threshold, the user's comfort needs are met first, that is, rapid heating is achieved, and there is no need to impose too many restrictions on the compressor frequency. The inner tube temperature threshold is the upper limit of the inner tube temperature that the air conditioner can accept within a preset time.

[0057] The first correction coefficient can correct the upper frequency limit of the compressor by a relatively low amplitude. In some embodiments, the value of the first correction coefficient can be zero, that is, the upper frequency limit of the compressor is maintained unchanged.

[0058] S205: When the indoor coil temperature is greater than or equal to the inner tube temperature threshold, determine a frequency correction coefficient according to the outdoor ambient temperature.

[0059] When the indoor coil temperature is greater than or equal to the internal tube temperature threshold, if the indoor coil temperature continues to rise, there may be a risk of overheating. At this time, the frequency correction coefficient can be determined in combination with the outdoor ambient temperature to correct the upper frequency limit.

[0060] Figure 3 FIG. 20 shows a flow chart of determining a frequency correction coefficient provided by some embodiments of the present application. Although a logical sequence is shown in the flow chart, in some cases, the operations shown or described may be performed in an order different from that shown in the drawings. The specific process of operation S205 may be as follows: Figure 3 As shown:

[0061] S301: Obtain outdoor ambient temperature.

[0062] As mentioned above, when the outdoor ambient temperature is low, the heating efficiency of the air conditioner is low, and the frequency of the compressor is higher than the required frequency when the outdoor ambient temperature is high. Therefore, the upper frequency limit correction value of the compressor when the outdoor ambient temperature is low can be higher than the upper frequency limit correction value when the outdoor ambient temperature is high.

[0063] In order to maintain the stability of frequency correction and reduce the large frequency changes, the frequency correction coefficient can be set according to the outdoor ambient temperature interval. In this embodiment, the outdoor ambient temperature is divided into three intervals as an example. It can be understood that other numbers of partitions are also within the protection scope of this application.

[0064] S303: When the outdoor ambient temperature is lower than the first external ring temperature, determine the frequency correction coefficient to be the first correction coefficient.

[0065] S305: When the outdoor ambient temperature is greater than or equal to the first external ring temperature and less than the second external ring temperature, determine the frequency correction coefficient to be the second correction coefficient.

[0066] S307: When the outdoor ambient temperature is greater than or equal to the second external ring temperature, determine the frequency correction coefficient to be a third correction coefficient.

[0067] The first outer ring temperature and the second outer ring temperature can be used to divide the outdoor ambient temperature into three temperature intervals. The first outer ring temperature and the second outer ring temperature can be temperature values ​​preset in advance.

[0068] The first correction coefficient is smaller than the second correction coefficient, and the second correction coefficient is smaller than the third correction coefficient.

[0069] Table 1 shows a comparison table of how to determine the frequency correction coefficient within a preset time in some embodiments of the present application. 内管 Indoor coil temperature, T 外环 represents the outdoor ambient temperature, A1 represents the first correction coefficient, A2 represents the second correction coefficient, and A3 represents the third correction coefficient. In the embodiment shown in Table 1, the inner pipe temperature threshold is 42°C, the first outer ring temperature is -12°C, and the second outer ring temperature is 0°C.

[0070] Table 1

[0071]

[0072] When determining the frequency correction coefficient within a preset time, some embodiments of the present application can first judge the internal pipe temperature condition. When the indoor coil temperature is within the 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 combination with the outdoor ambient temperature. Therefore, the control method provided by some embodiments of the present application can ensure the heating effect within a preset time and can also correct the frequency in a timely manner.

[0073] The following describes how to determine the frequency correction coefficient after the preset time.

[0074] Figure 4 FIG. 1 is a flow chart of determining a frequency correction factor according to some embodiments of the present application. Although a logical sequence is shown in the flow chart, in some cases, the operations shown or described may be performed in an order different from that shown in the drawings. The process of operation S105 may be as follows: Figure 4 As shown:

[0075] S401. Obtain outdoor ambient temperature.

[0076] As mentioned above, the frequency correction coefficient can be set in zones according to the intervals of the outdoor ambient temperature. In this embodiment, the outdoor ambient temperature is divided into three zones as an example for explanation. It can be understood that other numbers of zones are also within the protection scope of this application. In addition, the zone method for the outdoor ambient temperature after the preset time can be the same as that within the preset time, or it can be different.

[0077] S403: When the outdoor ambient temperature is lower than the first external ring temperature, determine the frequency correction coefficient to be the first correction coefficient.

[0078] S405: When the outdoor ambient temperature is greater than or equal to the first external ring temperature and less than the second external ring temperature, determine the frequency correction coefficient to be a fourth correction coefficient.

[0079] S407: When the outdoor ambient temperature is greater than or equal to the second external ring temperature, determine the frequency correction coefficient to be the fifth correction coefficient.

[0080] The first outer ring temperature and the second outer ring temperature can be used to divide the outdoor ambient temperature into three temperature intervals. The first outer ring temperature and the second outer ring temperature can be temperature values ​​preset in advance.

[0081] The first correction coefficient is smaller than the fourth correction coefficient, and the fourth correction coefficient is smaller than the fifth correction coefficient.

[0082] After the preset time, the demand for rapid heating decreases, and the upper frequency limit value can be corrected to a greater extent. In some embodiments, the fourth correction value can be greater than the second correction value, and the fifth correction value can be greater than the third correction value.

[0083] Table 2 shows a comparison table of how to determine the frequency correction coefficient after a preset time in some embodiments of the present application. 内管 Indoor coil temperature, T 外环 represents the outdoor ambient temperature, A1 represents the first correction coefficient, A4 represents the fourth correction coefficient, and A5 represents the fifth correction coefficient. In the embodiment shown in Table 1, the inner pipe temperature threshold is 42°C, the first outer ring temperature is -12°C, and the second outer ring temperature is 0°C.

[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 the present application, the frequency correction coefficient is determined in combination with the outdoor ambient temperature when the frequency correction coefficient is determined after the preset time. Therefore, the control method provided by some embodiments of the present application can correct the frequency in time after the preset time is reached, and frequent changes in frequency are not likely to occur.

[0087] The above describes in detail how to determine the frequency correction coefficient within and after the preset time. The following describes how to determine the upper frequency limit correction value of the compressor operation based on the frequency correction coefficient.

[0088] Figure 5FIG. 1 is a flow chart of determining a frequency upper limit correction value provided by some embodiments of the present application. Although a logical sequence is shown in the flow chart, in some cases, the operations shown or described may be performed in an order different from that shown in the drawings. The process of operation S107 may be as follows: Figure 5 As shown:

[0089] S501: Obtain the wind speed level of the indoor fan of the air conditioner.

[0090] The value of the wind speed level can be used to reflect the speed of the internal fan. The wind speed level is negatively correlated with the speed of the internal fan, that is, the larger the value of the wind speed level, the lower the speed of the internal fan, and vice versa.

[0091] S503: Obtain an upper limit value of the compressor frequency corresponding to the outdoor ambient temperature.

[0092] The upper frequency limit of the compressor is the upper frequency limit at which the compressor can operate under different outdoor ambient temperature conditions in the default state.

[0093] S505: Determine a frequency upper limit correction value according to the frequency upper limit value, the wind speed level and the frequency correction coefficient.

[0094] As mentioned above, in the heating mode, if the speed of the internal fan is low (the value of the wind speed gear is high), and the compressor runs at a higher frequency, it may cause the system to overheat, and then cause frequency fluctuations and conducted sound problems due to frequent frequency reduction. Therefore, some embodiments of the present application can correct the upper frequency limit value in combination with the wind speed gear. When the speed of the internal fan is low, that is, the wind speed gear is high, the frequency is corrected to a greater extent; conversely, the correction amplitude is smaller. The correction amplitude can be reflected by the difference between the frequency upper limit value and the frequency upper limit correction value. The difference between the frequency upper limit value and the frequency upper limit correction value is negatively correlated with the wind speed gear.

[0095] In some embodiments, the upper frequency limit correction value in operation S505 may be determined as follows:

[0096] F 上限修正 =F 上限 -A×B

[0097] Among them, F 上限修正 Indicates the frequency upper limit correction value, F 上限 Indicates the upper limit of frequency, A indicates the frequency correction coefficient, and B indicates the wind speed level. 上限 Negatively correlated with the outdoor ambient temperature. The higher the outdoor ambient temperature, the higher the corresponding frequency upper limit F 上限 On the contrary, the lower the outdoor ambient temperature, the lower the corresponding frequency upper limit F 上限 The higher it is.

[0098] Therefore, under the same other conditions, the higher the outdoor ambient temperature, the higher the frequency upper limit correction value F 上限修正 On the contrary, the lower the outdoor ambient temperature, the lower the frequency upper limit correction value F 上限修正 That is to say, when the outdoor environment is high, the heating efficiency of the compressor is also high and it can run at a lower frequency. Under the same other conditions, the larger the value of wind speed gear B (the lower the internal fan speed), the higher the frequency upper limit correction value F 上限修正 On the contrary, the smaller the value of wind speed gear B is (the higher the internal fan speed is), the higher the frequency upper limit correction value F is. 上限修正 That is to say, when the indoor fan speed is low, in order to prevent the heat from not being able to dissipate quickly and causing the indoor coil to overheat, the compressor operating frequency can be appropriately reduced.

[0099] The frequency correction coefficient A can be determined according to the method for determining the frequency correction coefficient described above. For example, the frequency correction coefficient A can be A1, A2, A3, A4 or A5. The wind speed level B can be a preset value in the air conditioner, and different wind speed levels correspond to different internal fan speeds. The smaller the value of the wind speed level B, the higher the internal fan speed.

[0100] In some embodiments, the first frequency correction coefficient A1 may be equal to 0. The second frequency correction coefficient A2 may be equal to 2. The third frequency correction coefficient A3 may be equal to 4. The fourth frequency correction coefficient A4 may be equal to 3. The fifth frequency correction coefficient A5 may be equal to 5.

[0101] In some embodiments, the wind speed level B corresponding to the maximum speed of the internal fan is equal to 0. The wind speed level B corresponding to the second speed of the internal fan is equal to 1. The wind speed level B corresponding to the third speed of the internal fan is equal to 2. By analogy, the air conditioner may include more wind speed levels.

[0102] Figure 6 An example diagram of an operation control method of an air conditioner provided by some embodiments of the present 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 drawings.

[0103] like Figure 6 As shown, in the method provided in this embodiment, after the air conditioner enters the heating mode, the continuous operation time of the compressor is obtained, and then it is determined whether the continuous operation time is greater than a preset time.

[0104] If it is within the preset time, the indoor coil temperature is obtained to determine whether the indoor coil temperature is less than the inner tube temperature threshold. If the indoor coil temperature is less than the inner tube temperature threshold, the frequency correction factor is determined to be the first correction factor. If the indoor coil temperature is greater than or equal to the inner tube temperature threshold, the frequency correction factor is determined based on the outdoor ambient temperature. For information on how to determine the frequency correction factor based on the outdoor ambient temperature, please refer to Figure 6 as well as Figure 3 The description content will not be repeated here.

[0105] If the preset time is exceeded, the frequency correction factor is determined according to the outdoor ambient temperature. For more information on how to determine the frequency correction factor according to the outdoor ambient temperature, please refer to Figure 6 as well as Figure 4 The description content will not be repeated here.
