Description

Technical Field

[0001] This invention relates to the field of home appliance control technology, and more specifically, to a defrosting control method and device for an air conditioner, and a computer-readable storage medium. Background Technology

[0002] Traditional defrosting methods for air conditioners are often determined based on laboratory tests and standard installation methods. However, the actual installation environments of air conditioners vary greatly, causing the preset defrosting entry and exit conditions to be ineffective in achieving rapid defrosting and energy saving. Although existing technologies provide some methods to solve the problem of long defrosting cycles by adjusting the logic in the defrosting process, they only reduce the mode switching time and do not effectively control the parameters in the defrosting process, thus having certain limitations in reducing the time of ineffective heating.

[0003] Existing defrosting methods have the following main shortcomings: 1) Traditional defrosting control methods may misjudge due to changes in external temperature and humidity, causing the air conditioner to frequently enter and exit defrosting mode. This not only affects the heating effect of the air conditioner but may also increase energy consumption and equipment wear; 2) To avoid excessively long defrosting times and customer discomfort, a maximum defrosting time limit is usually set. However, unreasonable defrosting entry conditions can lead to incomplete defrosting within the maximum time limit. Over time, the frost layer will become thicker and thicker, eventually resulting in unmelted frost and affecting reliability; 3) During the defrosting process, the equipment consumes a large amount of electrical energy. Unreasonable defrosting entry and exit conditions will reduce the operating efficiency of the equipment and increase energy consumption.

[0004] There is currently no effective solution to the problem that traditional defrosting control methods used in the aforementioned technologies fail to consider the changes in defrosting conditions as the air conditioner operates, resulting in poor defrosting performance.

When the current external pipe temperature reaches the current defrosting conditions, the air conditioner is controlled to perform a defrosting start operation or a defrosting stop operation. The current external pipe temperature is the current temperature collected from the external pipe at predetermined time intervals during the operation of the air conditioner. The above technical solution achieves the goal of continuously updating defrosting conditions based on monitoring the defrosting effect of the air conditioner, thus more accurately determining whether defrosting needs to be started and stopped. It realizes the technical effect of automatically updating the parameters of the air conditioner during the defrosting process through self-learning and updating the defrosting conditions in real time as the air conditioner operates. This improves the defrosting performance of the air conditioner and avoids ineffective defrosting. In turn, it solves the technical problem in related technologies where the traditional defrosting control method for defrosting the air conditioner does not take into account the fact that the defrosting conditions will change as the air conditioner operates, resulting in poor defrosting effect.

[0036] According to an embodiment of the present invention, a method embodiment of a defrosting control method for an air conditioner is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, 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.

[0037] Figure 2 This is a flowchart of a defrosting control method for an air conditioner according to an embodiment of the present invention, such as... Figure 2 As shown, the method includes the following steps:

[0038] Step S202: After determining that the air conditioner has exited the current defrosting stage, obtain the current average external pipe temperature of the air conditioner's external pipe within a predetermined time period, wherein the current defrosting stage is any defrosting stage other than the first defrosting stage and the second defrosting stage during the operation of the air conditioner.

[0039] In this embodiment, after the air conditioner exits the current defrosting stage, the temperature of the air conditioner's external pipe can be monitored, and its average temperature during a period of air conditioner operation can be obtained to provide a data basis for subsequent updates to the defrosting conditions.

[0040] Step S204: Obtain the first duration of the air conditioner in the first defrosting stage, the second duration of the air conditioner in the second defrosting stage, the first interval duration between the air conditioner exiting the first defrosting stage and entering the second defrosting stage, and the second interval duration between the air conditioner exiting the second defrosting stage and entering the current defrosting stage, wherein the second defrosting stage is the previous defrosting stage of the current defrosting stage, and the first defrosting stage is the previous defrosting stage of the second defrosting stage.

[0041] In this embodiment, the defrosting conditions for the next defrosting stage of the air conditioner can be updated in a cycle of three defrosting stages. The defrosting effect of the air conditioner can be analyzed by analyzing the defrosting duration of the first two defrosting stages and the interval between the two times of exiting defrosting and re-entering defrosting, thereby updating the defrosting conditions of the air conditioner.

[0042] It should be noted that since the analysis of the entry and exit conditions for the first three defrosting stages after the air conditioner is turned on does not meet the above-mentioned update conditions, other methods can be selected to update the defrosting conditions of the air conditioner.

[0043] Step S206: Adjust the current average external pipe temperature according to the first duration, the second duration, the first interval duration, and the second interval duration according to the first preset rule to obtain the current defrosting conditions of the air conditioner. The first preset rule is the rule for updating the current defrosting conditions of the air conditioner after the air conditioner exits the current defrosting stage.

[0044] In this embodiment, the first duration and the second duration, as well as the first interval duration and the second interval duration, can be compared respectively to analyze the defrosting effect of the air conditioner based on the comparison results, and the defrosting conditions of the air conditioner can be updated accordingly.

[0045] Step S208: When the current external pipe temperature reaches the current defrosting condition, control the air conditioner to perform a defrosting start operation or a defrosting stop operation. The current external pipe temperature is the current temperature of the external pipe collected at predetermined time intervals during the operation of the air conditioner.

[0046] In this embodiment, the current temperature of the external pipe in the air conditioner can be monitored and acquired in real time. When the temperature reaches the entry condition for the current defrosting, the air conditioner is controlled to start the defrosting operation. When the temperature reaches the exit condition for the current defrosting, the air conditioner is controlled to stop the defrosting operation and exit the current defrosting stage. At the same time, the defrosting conditions of the air conditioner are further updated based on the operating status of the air conditioner during this defrosting stage.

[0047] It should be noted that during the operation of the air conditioner, it is necessary to monitor and obtain the current temperature of the external pipe in real time, so as to determine whether the air conditioner needs to perform defrosting or stop defrosting based on the real-time temperature.

[0048] As can be seen from the above, through the technical solution provided by the above embodiments of the present invention, after determining that the air conditioner has exited the current defrosting stage, the current average external pipe temperature of the air conditioner within a predetermined time period can be obtained, wherein the current defrosting stage is any defrosting stage other than the first defrosting stage and the second defrosting stage during the operation of the air conditioner; the first duration of the air conditioner in the first defrosting stage, the second duration of the air conditioner in the second defrosting stage, the first interval duration between the air conditioner exiting the first defrosting stage and entering the second defrosting stage, and the second interval duration between the air conditioner exiting the second defrosting stage and entering the current defrosting stage can be obtained, wherein the second defrosting stage is the defrosting stage preceding the current defrosting stage, and the first defrosting stage is the defrosting stage preceding the second defrosting stage; according to the first duration, the second duration, the first interval duration, and the second interval duration, a first predetermined time period can be obtained; The system establishes rules to adjust the current average external pipe temperature to obtain the current defrosting conditions of the air conditioner. The first preset rule updates the current defrosting conditions after the air conditioner exits the current defrosting stage. When the current external pipe temperature reaches the current defrosting conditions, the system controls the air conditioner to perform either a defrosting start or defrosting stop operation. The current external pipe temperature is obtained by collecting data from the external pipe at predetermined time intervals during the air conditioner's operation. This achieves the goal of continuously iterating and updating the defrosting conditions based on monitoring the defrosting effect, thus more accurately determining whether defrosting needs to begin or end. It realizes the technical effect of automatically updating parameters during the air conditioner's defrosting process through self-learning and updating defrosting conditions in real time as the air conditioner operates, improving the defrosting performance of the air conditioner and avoiding ineffective defrosting.

[0049] Therefore, the technical solution provided by the above embodiments of the present invention solves the technical problem in the related art that the traditional defrosting control method for defrosting air conditioners does not take into account the fact that defrosting conditions will change as the air conditioner operates, resulting in poor defrosting effect.

[0050] The following combination Figure 3 The embodiments of the present invention will be described in detail below. Figure 3 This is a flowchart of an optional defrosting control method for an air conditioner according to an embodiment of the present invention.

[0051] According to the above embodiments of the present invention, the defrosting control method of the air conditioner further includes: when the first defrosting stage is the initial defrosting stage, obtaining the first average external pipe temperature of the external pipe within a predetermined time after the air conditioner exits the first defrosting stage, wherein the initial defrosting stage is the first defrosting stage after the air conditioner is started; updating the initial defrosting conditions of the air conditioner according to the first average external pipe temperature and a second preset rule to obtain the first defrosting conditions, wherein the second preset rule is a rule for updating the current defrosting conditions of the air conditioner after the air conditioner exits the initial defrosting stage or exits the target second defrosting stage, the target second defrosting stage is the defrosting stage after the initial defrosting stage, and the initial defrosting conditions include the conditions for the air conditioner to enter and exit the initial defrosting stage; when the first defrosting stage is the initial defrosting stage, obtaining the second average external pipe temperature of the external pipe within a predetermined time after the air conditioner exits the second defrosting stage; updating the first defrosting conditions of the air conditioner for the first time according to the second average external pipe temperature and the second preset rule to obtain the second defrosting conditions; and determining the second defrosting conditions as the defrosting conditions before the air conditioner enters the first current defrosting stage.

[0052] As above Figure 3 As shown, after the air conditioner is started, it is first determined whether the air conditioner is running in heating mode. Only when the air conditioner is running in heating mode is defrosting required. Therefore, the defrosting conditions of the air conditioner are updated in real time according to the method provided in the above embodiment of the present invention. Secondly, when the air conditioner enters defrosting mode for the first time after starting, the defrosting entry and exit conditions for the first defrosting stage (i.e., the initial defrosting stage) are based on the conditions preset by the program. After the air conditioner exits the first defrosting stage, the outdoor pipe temperature is detected after a period of stable normal heating operation (recommended value range: 5-15 min) (recommended detection cycle range: 1-10 min), and the average value T0 (i.e., ...) is calculated. Based on the detected first average external pipe temperature T0, the defrosting entry condition for the air conditioner can be updated to: T_outer_pipe ≤ T0 - first preset value (recommended value range: 3-8℃), and the defrosting exit condition can be updated to: T_outer_pipe > T0 + second preset value (recommended value range: 0-6℃). The defrosting conditions obtained here are the entry and exit conditions for the second defrosting stage of the air conditioner. By accurately judging the condenser frost status through the drop in outdoor pipe temperature, and then updating the defrosting exit condition to a pipe temperature that is a certain value higher than the normal non-frost pipe temperature, the situation of ineffective defrosting due to unreasonable defrosting exit condition settings can be avoided when there is no actual frost, thus shortening the defrosting cycle and improving low-temperature heating capacity and comfort.

[0053] In the embodiments provided by the present invention, the air conditioner in the room is in heating mode. Then the system can obtain the average condensing temperature T0 by using the outdoor temperature sensor after the air conditioner has been running stably in normal heating mode for a period of time after defrosting. Based on the average condensing temperature T0, the system can easily determine the drop in condenser temperature after frosting and accurately define the degree to which the pipe temperature rises after defrosting has actually ended, so as to shorten the defrosting cycle.

[0054] In addition, after the air conditioner exits the first defrosting stage, the outdoor pipe temperature can be detected after the air conditioner has been running stably in normal heating mode for a period of time after exiting the first defrosting stage (the recommended detection period is 1-10 minutes), and the average value T1 (second average outdoor pipe temperature) can be calculated. Based on the detected second average outdoor pipe temperature T1, the defrosting conditions of the air conditioner can be updated again. The defrosting entry condition can be updated to: T_outer_pipe ≤ T1 - first preset value, and the defrosting exit condition can be updated to: T_outer_pipe > T1 + second preset value. The defrosting conditions obtained here are the defrosting entry and exit conditions of the third defrosting stage of the air conditioner (i.e., the first current defrosting stage in the above embodiment of the present invention).

[0055] It should be noted that the first preset value here is the first preset temperature value in the embodiment of the present invention, and the second preset value here is the second preset temperature value in the embodiment of the present invention.

[0056] According to the above embodiments of the present invention, before updating the initial defrosting conditions of the air conditioner according to the first average external pipe temperature and the second preset rule to obtain the first defrosting conditions, the defrosting control method of the air conditioner further includes: after the air conditioner is started, acquiring the historical operation record of the air conditioner; if the historical operation record indicates that the air conditioner was in a power-off state before starting, determining the initial defrosting conditions as preset defrosting conditions; if the historical operation record indicates that the air conditioner was in a standby state before starting, determining the initial defrosting conditions as the last historical defrosting conditions, wherein the last historical defrosting conditions are the last defrosting conditions of the air conditioner before entering the standby state.

[0057] Specifically, after the air conditioner is started, it is first determined whether the air conditioner is being used for the first time after a power outage. If the air conditioner is being used for the first time, it is highly likely that the air conditioner is newly installed or has not been used for a long time and is being restarted. Therefore, the defrosting entry and exit conditions are based on the preset conditions of the program, and then the learning and iteration are performed again. If the air conditioner is turned off and then turned on again by remote control, the parameters of the air conditioner's previous operation will be memorized in the main board. After the air conditioner is turned off and then turned on again by remote control, the entry and exit conditions of the air conditioner's first defrosting mode will be based on the parameters before it was turned off.

[0058] The program preset defrosting entry and defrosting exit conditions can be as follows: 1) Defrosting entry conditions: ① When the outer ring temperature (T_outer ring) is ≥ -8℃ and any of the following conditions are met for 1 minute, the air conditioner is controlled to enter defrosting: a. T_outer ring temperature ≥ 5℃, T_outer pipe temperature ≤ -2℃; b. 0℃ ≤ T_outer ring temperature < 5℃, T_outer pipe temperature ≤ -6℃; c. -5℃ ≤ T_outer ring temperature < 0℃, T_outer pipe temperature -10℃; d. -10℃ ≤ T_outer ring temperature < -5℃, T_outer pipe temperature ≤ T_outer ring temperature -6℃; ② When the outer ring temperature is < -10℃ and the outer pipe temperature is < T_outer ring temperature -6℃ (minimum -20℃) for 1 minute, the air conditioner is controlled to enter defrosting; 2) Defrosting exit conditions: When the outer pipe temperature increases by 10℃ compared to the pipe temperature when entering defrosting, the air conditioner is controlled to exit defrosting.

[0059] It should be noted that after the air conditioner is started, the defrosting conditions for the first defrosting stage can be the conditions preset by the program or the previous defrosting conditions recorded in the air conditioner system before startup; the defrosting conditions for the second and third defrosting stages can be based on the defrosting conditions updated in the above embodiments of the present invention; and the defrosting conditions for the fourth defrosting stage of the air conditioner and each subsequent defrosting stage before the air conditioner is turned off or exits the heating mode can be obtained by analyzing the defrosting effect of the air conditioner using the defrosting duration of the first two defrosting stages in the three defrosting stages before that defrosting stage, as well as the interval between the two times after exiting defrosting and re-entering defrosting.

[0060] According to the above embodiments of the present invention, adjusting the current average external pipe temperature according to a first preset rule based on a first duration, a second duration, a first interval duration, and a second interval duration to obtain the current defrosting conditions of the air conditioner includes: comparing the first interval duration and the second interval duration to obtain a first comparison result; calculating the difference between the first duration and the second duration to obtain a defrosting duration deviation; comparing the defrosting duration deviation with a deviation threshold to obtain a second comparison result; comparing the second duration with a duration threshold to obtain a third comparison result; and adjusting the current average external pipe temperature according to the first comparison result, the second comparison result, and the third comparison result according to the first preset rule to obtain the current defrosting conditions of the air conditioner.

[0061] Specifically, as above Figure 3 As shown, when updating the defrosting conditions for the next defrosting stage of the air conditioner in a cycle of three defrosting stages, the defrosting duration of the first two defrosting stages (where the defrosting duration T of the first defrosting stage is used) can be considered. 化 The defrosting time T of the second defrosting stage ′ 化The defrosting process is compared by comparing the defrosting time of the second defrosting stage with the maximum defrosting time limit (i.e., the time threshold). The time interval Δt1 (the first interval) between the air conditioner exiting the first defrosting stage and entering the second defrosting stage, and the time interval Δt2 (the second interval) between the air conditioner exiting the second defrosting stage and entering the third defrosting stage, are also compared. Based on these comparisons, the defrosting effect of the air conditioner is analyzed, and the entry and exit conditions for the next defrosting stage are updated. During the update, the average value T of the external pipe temperature after the air conditioner exits the previous defrosting stage is monitored and adjusted numerically to obtain the corresponding defrosting conditions.

[0062] In a specific embodiment of the present invention, the current defrosting conditions include current defrosting entry conditions and current defrosting exit conditions. Based on a first comparison result, a second comparison result, and a third comparison result, the current average external pipe temperature is adjusted according to a first preset rule to obtain the current defrosting conditions for the air conditioner. This includes: if the first comparison result indicates that the first interval duration is not greater than the second interval duration, and if the second comparison result indicates that the defrosting duration deviation is not greater than a deviation threshold, then the current defrosting entry condition is determined to be: the current external pipe temperature is not greater than a first target threshold obtained by subtracting the current average external pipe temperature from the first preset temperature value. The current defrosting exit condition is determined to be: the current external pipe temperature is greater than a second target threshold obtained by adding the current average external pipe temperature to the second preset temperature value. The first preset temperature value is the temperature value used to adjust the current average external pipe temperature when determining the current defrosting entry condition, and the second preset temperature value is the temperature value used to determine the current defrosting exit condition. The condition is to adjust the current average external tube temperature to the specified temperature value. If the second comparison result indicates that the defrosting time deviation is greater than the deviation threshold and the third comparison result indicates that the second time is less than the time threshold, then the current defrosting entry condition is determined to be: the current average external tube temperature is not greater than the third target threshold obtained by adding the first target threshold and the first preset temperature compensation value, and the current defrosting exit condition is determined to be: the current external tube temperature is greater than the second target threshold. If the second comparison result indicates that the defrosting time deviation is greater than the deviation threshold and the third comparison result indicates that the second time is not less than the time threshold, then the current defrosting entry condition is determined to be: the current average external tube temperature is not greater than the fourth target threshold obtained by adding the first target threshold and the second preset temperature compensation value, and the current defrosting exit condition is determined to be: the current average external tube temperature is greater than the fifth target threshold obtained by adding the second target threshold and the first preset temperature compensation value, wherein the second preset temperature compensation value is greater than the first preset temperature compensation value.

[0063] Specifically, if Δt1≤Δt2 and |T ′ 化 -T 化If |≤2min, then the defrosting entry condition under the corresponding outdoor ambient temperature is: T_outer_pipe ≤ T - first preset value, and the defrosting exit condition is: T_outer_pipe > T + second preset value. This indicates that after the defrosting entry and exit conditions are controlled according to the parameters updated for the second time, the heating cycle becomes longer, effectively delaying the time to enter defrost, resulting in better comfort. The defrosting time does not change much, indicating that the thickness and area of ​​frost do not change much after delaying the time to enter defrost. There is no problem using these defrosting entry and exit conditions for the subsequent foundation. Further parameter adjustments are needed.

[0064] If Δt1≤Δt2 and 2min<|T ′ 化 -T 化 |and T ′ 化 If the defrosting time limit is less than the maximum defrosting time limit (recommended value range: 8-15min), then the defrosting entry condition under the corresponding outdoor ambient temperature is: T_outer_pipe ≤ T - first preset value + compensation value ΔT1 (i.e., the first preset temperature compensation value, recommended value range: 1-5℃), and the defrosting exit condition is: T_outer_pipe > T + second preset value. This indicates that after the defrosting entry and exit conditions are controlled according to the parameters updated for the second time, the heating cycle becomes longer, effectively delaying the time to enter defrosting, resulting in better comfort. However, the defrosting time is longer, but it does not reach the maximum defrosting time limit. This means that after delaying the time to include defrosting, the thickness and area of ​​the frost become larger. The defrosting entry temperature can be increased to allow the air conditioner to enter defrosting earlier, entering defrosting when the frost is thinner, thereby improving defrosting efficiency.

[0065] If Δt1≤Δt2 and 2min<|T ′ 化 -T 化 |and T ′ 化If the value is greater than or equal to the maximum defrosting time limit, then the defrosting entry condition under the corresponding outdoor ambient temperature is: T_outer_pipe ≤ T - first preset value + compensation value ΔT2 (i.e., the second preset temperature compensation value, the recommended value range is 1-5℃, but in the parameter setting ΔT2 > ΔT1), and the defrosting exit condition is: T_outer_pipe > T + second preset value + compensation value ΔT1. This indicates that after the defrosting entry and exit conditions are controlled according to the parameters updated for the second time, the heating operation cycle has become longer, effectively delaying the time to enter defrosting, resulting in better comfort. However, the defrosting time has increased, and the defrosting time has reached the maximum defrosting time limit, indicating that after delaying the time to include defrosting, the thickness and area of ​​the frost have become larger, and there is also a possibility of incomplete defrosting. Therefore, it is necessary to increase the defrosting entry temperature to allow the air conditioner to enter defrosting earlier, entering defrosting when the frost is thinner. At the same time, in order to avoid incomplete defrosting leading to incomplete defrosting of the condenser after accumulated defrosting, it is necessary to increase the pipe temperature condition when exiting defrosting to make defrosting more thorough.

[0066] In another specific embodiment of the present invention, the current defrosting conditions include current defrosting entry conditions and current defrosting exit conditions. Based on the first comparison result, the second comparison result, and the third comparison result, the current average external pipe temperature is adjusted according to a first preset rule to obtain the current defrosting conditions for the air conditioner. This includes: if the first comparison result indicates that the first interval duration is greater than the second interval duration, and if the second comparison result indicates that the defrosting duration deviation is not greater than a deviation threshold, then the current defrosting entry condition is determined to be: the current average external pipe temperature is not greater than the sixth target threshold obtained by subtracting the first target threshold from the first preset temperature compensation value; and the current defrosting exit condition is determined to be: the current average external pipe temperature is not greater than the sixth target threshold obtained by subtracting the first target threshold from the first preset temperature compensation value. If the temperature is greater than the second target threshold minus the first preset temperature compensation value, the seventh target threshold is obtained. If the second comparison result indicates that the defrosting time deviation is greater than the deviation threshold and the third comparison result indicates that the second time is less than the time threshold, then the current defrosting entry condition is determined to be: the current average external tube temperature is not greater than the sixth target threshold, and the current defrosting exit condition is determined to be: the current external tube temperature is greater than the second target threshold. If the second comparison result indicates that the defrosting time deviation is greater than the deviation threshold and the third comparison result indicates that the second time is not less than the time threshold, then the current defrosting entry condition is determined to be: the current average external tube temperature is not greater than the fourth target threshold, and the current defrosting exit condition is determined to be: the current external tube temperature is greater than the second target threshold.

[0067] Specifically, if Δt1>Δt2 and |T ′ 化 -T 化If the defrosting time is ≤2min, then the defrosting entry condition under the corresponding outdoor ambient temperature is: T_outer_pipe ≤ T - first preset value (recommended value range: 3-8℃) - compensation value ΔT1; the defrosting exit condition is: T_outer_pipe > T + second preset value - compensation value ΔT1. This indicates that after the defrosting entry and exit conditions are controlled according to the updated parameters, the heating cycle is shortened, resulting in a shorter defrosting time and a decrease in comfort. The defrosting time remains relatively unchanged, suggesting that even with earlier defrosting, the thickness and area of ​​the frost do not change significantly. Therefore, it is possible to try lowering the defrosting entry temperature to delay the defrosting process, allowing the air conditioner to enter defrosting only when the frost is slightly thicker, thus improving comfort. Alternatively, lowering the defrosting exit temperature can reduce the defrosting time and further improve product comfort.

[0068] If Δt1 > Δt2 and 2min < |T ′ 化 -T 化 |and T ′ 化 If the defrosting time limit is less than the maximum limit, then the defrosting entry condition under the corresponding outdoor ambient temperature is: T_outer_pipe ≤ T - first preset value - compensation value ΔT1, and the defrosting exit condition is: T_outer_pipe > T + second preset value. This indicates that after the defrosting entry and exit conditions are controlled according to the parameters updated for the second time, the heating cycle has become shorter, resulting in a shorter defrosting time and a worse comfort effect. The large change in defrosting time indicates that even if defrosting is initiated earlier, the thickness and area of ​​the frost still change significantly. This suggests that the ambient humidity may be higher or the environment may make frost formation easier. To improve comfort, the defrosting entry temperature can be lowered to delay the air conditioner from entering defrosting, allowing it to enter defrosting when the frost is slightly thicker. To avoid incomplete defrosting, the defrosting exit condition remains unchanged.

[0069] If Δt1 > Δt2 and 2min < |T ′ 化 -T 化 |and T ′ 化If the defrosting time limit is greater than or equal to the maximum defrosting time limit, then the defrosting entry condition under the corresponding outdoor ambient temperature is: T_outer_pipe ≤ T - first preset value + compensation value ΔT2, and the defrosting exit condition is: T_outer_pipe > T + second preset value. This indicates that after the defrosting entry and exit conditions are controlled according to the updated parameters, the heating cycle has shortened, resulting in a shorter defrosting time and a decrease in comfort. Simultaneously, the significant change in defrosting time suggests that even with earlier defrosting, the thickness and area of ​​frost still vary considerably, indicating that the ambient humidity may be higher or the environment may make frost formation more likely. To improve reliability, the defrosting entry temperature can be increased to allow the air conditioner to defrost more quickly, preventing the frost thickness and area from increasing. Furthermore, since the defrosting time has reached the maximum defrosting time limit, the defrosting time is long, and there may be instances of frost not defrosting. To avoid incomplete defrosting, the pipe temperature condition at defrosting exit needs to be increased to ensure more thorough defrosting.

[0070] It should be noted that the specific values ​​of the suggested values ​​involved in the above embodiments of the present invention are all optional examples. In actual application, they can be selected according to the actual situation, and no specific restrictions are imposed here.

[0071] According to the above embodiments of the present invention, the current defrosting conditions include current defrosting entry conditions and current defrosting exit conditions, and the current external pipe temperature includes a first current external pipe temperature and a second current external pipe temperature. When the current external pipe temperature reaches the current defrosting conditions, the air conditioner is controlled to perform a defrosting start operation or a defrosting stop operation, including: after the air conditioner exits the current defrosting stage, acquiring the first current external pipe temperature at predetermined time intervals; when the current external pipe temperature reaches the current defrosting entry conditions, controlling the air conditioner to perform a defrosting start operation to enter a target defrosting stage, wherein the target defrosting stage is the next defrosting stage after the current defrosting stage; during the operation of the air conditioner in the target defrosting stage, acquiring the second current external pipe temperature at predetermined time intervals; and when the second current external pipe temperature reaches the current defrosting exit conditions, controlling the air conditioner to perform a defrosting stop operation.

[0072] Optionally, both the first current external pipe temperature and the second current external pipe temperature mentioned above are the external pipe temperatures of the air conditioner, only they are the external pipe temperatures at different times.

[0073] Specifically, the current temperature of the external pipe in the air conditioner can be monitored and obtained in real time. When the temperature reaches the entry condition for the current defrosting, the air conditioner is controlled to start the defrosting operation. When the temperature reaches the exit condition for the current defrosting, the air conditioner is controlled to stop the defrosting operation and exit the current defrosting stage. At the same time, the defrosting conditions of the air conditioner are further updated based on the operating status of the air conditioner during this defrosting stage.

[0074] It should be noted that during the operation of the air conditioner, it is necessary to monitor and obtain the current temperature of the external pipe in real time, so as to determine whether the air conditioner needs to perform defrosting or stop defrosting based on the real-time temperature.

[0075] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to this application. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to this application.

[0076] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in the various embodiments of this application.

[0077] According to embodiments of the present invention, a defrosting control device for an air conditioner for implementing the above-described defrosting control method for an air conditioner is also provided. Figure 4 This is a schematic diagram of a defrosting control device for an air conditioner according to an embodiment of the present invention, as shown below. Figure 4 As shown, the device includes: a first acquisition unit 41, a second acquisition unit 43, a third acquisition unit 45, and a control unit 47. The defrosting control device for this air conditioner will be described in detail below.

[0078] The first acquisition unit 41 is used to acquire the current average external pipe temperature of the air conditioner within a predetermined time after determining that the air conditioner has exited the current defrosting stage. The current defrosting stage is any defrosting stage other than the first defrosting stage and the second defrosting stage during the operation of the air conditioner.

[0079] The second acquisition unit 43 is used to acquire the first duration of the air conditioner in the first defrosting stage, the second duration of the air conditioner in the second defrosting stage, the first interval duration between the air conditioner exiting the first defrosting stage and entering the second defrosting stage, and the second interval duration between the air conditioner exiting the second defrosting stage and entering the current defrosting stage, wherein the second defrosting stage is the previous defrosting stage of the current defrosting stage, and the first defrosting stage is the previous defrosting stage of the second defrosting stage.

[0080] The third acquisition unit 45 is used to adjust the current average external pipe temperature according to the first duration, the second duration, the first interval duration and the second interval duration according to the first preset rule, so as to obtain the current defrosting conditions of the air conditioner. The first preset rule is the rule for updating the current defrosting conditions of the air conditioner after the air conditioner exits the current defrosting stage.

[0081] The control unit 47 is used to control the air conditioner to perform a defrost start operation or a defrost stop operation when the current external pipe temperature reaches the current defrost condition. The current external pipe temperature is the current temperature of the external pipe collected at predetermined time intervals during the operation of the air conditioner.

[0082] It should be noted that the first acquisition unit 41, the second acquisition unit 43, the third acquisition unit 45 and the control unit 47 mentioned above correspond to steps S202 to S208 in the above embodiments. The four units and the corresponding steps implement the same instances and application scenarios, but are not limited to the content disclosed in the above embodiments.

[0083] As can be seen from the above, in the solution described in the above embodiments of the present invention, the first acquisition unit can obtain the current average external pipe temperature of the air conditioner within a predetermined time after determining that the air conditioner has exited the current defrosting stage. The current defrosting stage is any defrosting stage during the operation of the air conditioner other than the first and second defrosting stages. Then, the second acquisition unit obtains the first duration of the air conditioner in the first defrosting stage, the second duration of the air conditioner in the second defrosting stage, the first interval duration between the air conditioner exiting the first defrosting stage and entering the second defrosting stage, and the second interval duration between the air conditioner exiting the second defrosting stage and entering the current defrosting stage. The second defrosting stage is the previous defrosting stage of the current defrosting stage, and the first defrosting stage is the previous defrosting stage of the second defrosting stage. Then, the third acquisition unit obtains the first duration, the second duration, the first interval duration, and the second interval duration based on the first duration, the second duration, the first interval duration, and the second interval duration. The average external pipe temperature is adjusted according to a first preset rule at intervals to obtain the current defrosting conditions of the air conditioner. The first preset rule is the rule for updating the current defrosting conditions of the air conditioner after it exits the current defrosting stage. Finally, when the current external pipe temperature reaches the current defrosting conditions, the control unit controls the air conditioner to perform a defrosting start operation or a defrosting stop operation. The current external pipe temperature is the current temperature of the external pipe collected at predetermined time intervals during the operation of the air conditioner. This achieves the goal of continuously iterating and updating the defrosting conditions based on monitoring the defrosting effect of the air conditioner, so as to more accurately determine whether defrosting needs to be started or stopped. This realizes the technical effect of automatically updating the parameters of the air conditioner defrosting process through self-learning and updating the defrosting conditions in real time as the air conditioner operates, thereby improving the defrosting performance of the air conditioner and avoiding ineffective defrosting.

[0084] Therefore, the technical solution provided by the above embodiments of the present invention solves the technical problem in the related art that the traditional defrosting control method for defrosting air conditioners does not take into account the fact that defrosting conditions will change as the air conditioner operates, resulting in poor defrosting effect.

[0085] In an optional embodiment of the present invention, the defrosting control device of the air conditioner further includes: a fourth acquisition unit, configured to acquire, when the first defrosting stage is the initial defrosting stage, a first average external pipe temperature within a predetermined time period after the air conditioner exits the first defrosting stage, wherein the initial defrosting stage is the first defrosting stage after the air conditioner is started; and a fifth acquisition unit, configured to update the initial defrosting conditions of the air conditioner according to the first average external pipe temperature and a second preset rule to obtain the first defrosting conditions, wherein the second preset rule updates the current defrosting conditions of the air conditioner after the air conditioner exits the initial defrosting stage or exits the target second defrosting stage. The new rule stipulates that the target second defrosting stage is the defrosting stage following the initial defrosting stage, and the initial defrosting conditions include the conditions for the air conditioner to enter and exit the initial defrosting stage; the sixth acquisition unit is used to acquire the second average external pipe temperature within a predetermined time after the air conditioner exits the second defrosting stage when the first defrosting stage is the initial defrosting stage; the seventh acquisition unit is used to update the first defrosting conditions of the air conditioner for the first time according to the second preset rule based on the second average external pipe temperature to obtain the second defrosting conditions; the first determination unit is used to determine that the second defrosting conditions are the defrosting conditions before the air conditioner enters the first current defrosting stage.

[0086] In an optional embodiment of the present invention, the defrosting control device of the air conditioner further includes: an eighth acquisition unit, configured to acquire the historical operation record of the air conditioner after the air conditioner is started, before updating the initial defrosting condition of the air conditioner according to the first average external pipe temperature and the second preset rule to obtain the first defrosting condition; a second determination unit, configured to determine the initial defrosting condition as the preset defrosting condition when the historical operation record indicates that the air conditioner was in a power-off state before starting; and a third determination unit, configured to determine the initial defrosting condition as the last historical defrosting condition when the historical operation record indicates that the air conditioner was in a standby state before starting, wherein the last historical defrosting condition is the last defrosting condition of the air conditioner before entering the standby state.
