[0034] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0041] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0042] In winter, if the air conditioner is used for heating, the moisture in the air will form frost or ice on the surface of the air conditioner outdoor unit. This is because when the air conditioner outdoor unit is heating or working in a low temperature environment, the temperature of the air conditioner outdoor unit is lower than the dew point temperature of the surrounding air, causing the water vapor on the surface of the air conditioner outdoor unit to condense and then freeze into frost or ice, which is the defrosting problem. Defrosting will reduce the heating capacity of the air conditioner and even cause the air conditioner to fail to work properly. At the same time, defrosting will also accelerate the wear of the air conditioner outdoor unit and reduce the service life of the air conditioner, so the air conditioner needs to be defrosted. Generally, the air conditioner uses the method of switching the four-way valve and performing a refrigeration cycle to defrost. In this way, when defrosting, the indoor unit needs to stop running, so it cannot provide heat to the indoor space, thereby reducing the indoor temperature. Therefore, a suitable control method is needed to ensure the indoor heating effect.

[0043] In the related technology, the air conditioner defrost is mainly controlled by collecting the ambient temperature, coil temperature and heat exchanger temperature to control the compressor operating frequency, expansion valve steps, fan speed and throttling device opening during air conditioner defrosting. Although the above technical solution can reduce the frosting speed of the air conditioner and reduce the number of defrosting times of the air conditioner, thereby improving the indoor heating effect. However, in some cases where the outdoor temperature is low, the air conditioner may frequently enter defrosting, resulting in limited improvement in the indoor heating effect.

[0044] In view of this, the present disclosure provides an air conditioning control method, device, storage medium and air conditioner, which can adaptively adjust the control of the air conditioner according to the frequency of defrosting during the current operation of the air conditioner, reduce the frequency of defrosting of the air conditioner, and better improve the indoor heating effect while taking into account defrosting.

[0045] Figure 1 is a flow chart of an air conditioning control method according to an exemplary embodiment. Figure 1 As shown, the air conditioning control method includes the following steps:

[0046] In step S101, the frequency of defrosting during the current operation of the air conditioner is determined;

[0047] In step S102, according to the frequency of defrosting, the operating parameters of the air conditioner are adjusted to reduce the frosting speed of the air conditioner and / or reduce the defrost trigger temperature of the air conditioner to obtain target operating parameters, wherein the defrost trigger temperature is used to trigger the air conditioner to enter the defrost mode;

[0048] In step S103, the air conditioner is controlled according to the target operating parameters.

[0049] It should be understood that defrosting is the frost on the surface of the outdoor unit of the air conditioner due to the large temperature difference between indoor and outdoor during the heating process of the air conditioner, which will reduce the indoor heating effect of the air conditioner and may also damage the parts of the air conditioner or cause the air conditioner to be scrapped prematurely. When the air conditioning system detects frost on the surface of the outdoor unit, the system will temporarily shut down the compressor and continue to run the fan indoors, but will not output hot air, and guide the hot air flow to heat the surface of the outdoor unit to eliminate the frost.

[0050] In addition, it should be understood that the defrost frequency refers to the frequency of defrosting of the air conditioner during this operation period, which can characterize the degree of influence of air conditioner defrosting on the indoor heating effect. Therefore, directly adjusting the operating parameters of the air conditioner according to the defrost frequency can more effectively reduce the negative impact of defrosting on the user's heating experience. Secondly, the defrost trigger temperature is a type of control parameter of the air conditioner. By receiving the relevant temperature sent back by the air conditioner temperature sensor and comparing it with the defrost trigger temperature, it is determined whether the air conditioner enters the defrost mode. For example, in terms of air conditioner defrosting, at least one of the following temperature sensors can be used: evaporator outlet temperature sensor, outdoor temperature sensor, and external pipe temperature sensor.

[0051] Through the above steps, the frequency of defrosting of the air conditioner can be reduced, and while taking into account defrosting, the indoor heating effect and user experience can be better improved; at the same time, the above solution does not require hardware modification, has low cost, strong versatility, and is suitable for most air conditioners.

[0052] In order to enable those skilled in the art to better understand the air conditioning control method provided by the present disclosure, the above steps are described in detail with examples below.

[0053] In one possible manner, step S102 may include:

[0054] According to the frequency of defrosting, the upper limit operating frequency of the compressor of the air conditioner is reduced, wherein the upper limit operating frequency of the compressor has a positive correlation with the frosting speed of the air conditioner.

[0055] It should be understood that the air conditioning compressor is an important component in the air conditioning system. In the heating mode, its main function is to suck in low-temperature and low-pressure refrigerant gas, increase its temperature and pressure through compression, and then discharge the high-temperature and high-pressure refrigerant gas into the room, thereby producing a heating effect. The operating frequency of the compressor refers to the number of times the compressor rotates per minute, generally expressed in Hertz (Hz) or revolutions per minute (RPM). The operating frequency of the compressor directly affects the heating efficiency of the air conditioning system. The upper limit operating frequency of the compressor is the upper limit of the operating frequency of the air conditioning compressor. When this upper limit frequency is reached, the operating frequency of the compressor will not increase.

[0056] It should also be understood that in the heating mode of the air conditioner, the compressor needs to run at a higher frequency to generate enough heat to prevent the indoor temperature from being too low. However, if the operating frequency of the compressor is too high and the running time is too long within a certain period of time, it is easy to cause condensation and frost on the surface of the outdoor unit. This is because at a high frequency, the indoor and outdoor heat exchange of the air conditioner is frequent, and the outdoor unit temperature drops quickly. When it drops to the frost point, the outdoor unit begins to frost, and the temperature continues to drop, the speed of frost will accelerate, and defrosting will be more frequent and slower.

[0057] Therefore, by reducing the upper limit operating frequency of the compressor of the air conditioner according to the frequency of defrosting, the frosting speed of the air conditioner can be reduced, thereby reducing the frequency of defrosting of the air conditioner.

[0058] In one possible approach, Figure 2 As shown, according to the frequency of defrosting, the upper limit operating frequency of the air conditioner compressor can be reduced, which may include:

[0059] When the defrosting frequency is greater than or equal to the first threshold, the upper limit operating frequency of the compressor of the air conditioner is reduced by a first preset frequency value;

[0060] When the defrost frequency is less than the first threshold and greater than or equal to the second threshold, the upper limit operating frequency of the air conditioner compressor is reduced by a second preset frequency value, wherein the second preset frequency value is less than the first preset frequency value.

[0061] It should be understood that by making different adjustments to the upper limit operating frequency of the compressor according to different situations of the frequency of defrosting, the air conditioner can be controlled more finely. In the embodiment of the present disclosure, the value of the frequency of defrosting is divided into two intervals. Of course, the intervals of the value of the frequency of defrosting can also be divided more finely for better fine control. When the frequency of defrosting is large, exceeding the first threshold, the upper limit operating frequency of the compressor can be reduced by a larger preset frequency value (i.e., the first preset frequency value). When the frequency of defrosting is large, but does not exceed the first threshold, but only exceeds the second threshold, the upper limit operating frequency of the compressor can be reduced by a smaller preset frequency value (i.e., the second preset frequency value). When the frequency of defrosting is small, less than the second threshold, the upper limit operating frequency of the compressor can maintain the status quo. In the above manner, a fine adjustment of the upper limit operating frequency of the compressor can be achieved.

[0062] For example, the first threshold value may be a ratio of the number of times to the duration or a ratio of two durations. For example, the first threshold value may be any of the following values: 0.5 times / hour, 1 time / hour, 1.5 times / hour, 2 times / hour, preferably 1.5 times / hour. Or the first threshold value may be any of the following values: 0.1, 0.15, 0.2, 0.25. The second threshold value may be a ratio of the number of times to the duration or a ratio of two durations. For example, the second threshold value may be any of the following values: 0.2 times / hour, 0.6 times / hour, 1 time / hour, 1.2 times / hour, preferably 1 time / hour. Or the second threshold value may be any of the following values: 0.02, 0.04, 0.06, 0.08. The first preset frequency may be any of the following values: 3Hz, 4Hz, 5Hz, 6Hz, preferably 5Hz. The second preset frequency may be any of the following values: 1Hz, 2Hz, 3Hz, 4Hz, preferably 3Hz.

[0063] By adjusting the upper limit operating frequency of the compressor as described above, the frosting speed of the air conditioner can be reduced, and the air conditioner operating parameters can be finely adjusted, thereby reducing the frequency of defrosting the air conditioner.

[0064] In one possible manner, step S102 may include:

[0065] According to the frequency of defrosting, the outer pipe judgment temperature of the air conditioner is lowered. The outer pipe judgment temperature is the outer pipe temperature to be reached when the air conditioner enters the defrost mode.

[0066] It should be understood that, under normal circumstances, the temperature of the outer tube is lower than the ambient temperature, but not lower than the temperature inside the outdoor heat exchanger. Therefore, when frost appears on the surface of the outer tube, it can usually be determined that the outdoor heat exchanger has been frosted and needs to be defrosted. To determine whether the air conditioning system has entered the defrost mode based on the outer tube temperature, it is necessary to monitor the temperature of the outer tube in real time, that is, to determine the outer tube temperature at the current time when the air conditioner is running, and usually the outer tube temperature needs to be sampled, filtered and converted.

[0067] For example, first, the main board of the air conditioner outdoor unit samples the temperature of the outer tube, and the outer tube temperature sensor transmits the outer tube temperature value to the main board. The main board receives the transmitted information regularly and generates a sampling signal of the relationship between temperature and time. Then the main board filters the sampled signal. The filtering in this example is performed by taking the average value after sampling 32 times. The number of sampling times represents the real-time nature of the sampling. The more times means the higher the real-time nature, and the more accurately the outer tube temperature at the current operating moment can be obtained. The filtering depth in different situations can be determined according to actual needs. After filtering, the main board performs AD (Analog-to-Digital Conversion) conversion on the signal to obtain a more accurate outer tube temperature at the current moment.

[0068] It should also be understood that the air conditioning system obtains the outer tube temperature through the above process, and then compares it with the outer tube judgment temperature to determine whether it needs to enter the defrost mode. When the outer tube temperature of the air conditioner drops to the outer tube judgment temperature, the air conditioner enters the defrost mode. Therefore, the higher the outer tube judgment temperature, the easier it is for the air conditioner to trigger the defrost mode, which may increase the frequency of defrosting.

[0069] It should also be understood that step S102 in the disclosed embodiment can be to reduce the upper limit operating frequency of the air conditioner compressor according to the frequency of defrosting to obtain the target operating parameters; it can also be to reduce the outer pipe judgment temperature of the air conditioner according to the frequency of defrosting to obtain the target operating parameters; it can also be to reduce the upper limit operating frequency of the air conditioner compressor and reduce the outer pipe judgment temperature of the air conditioner according to the frequency of defrosting to obtain the target operating parameters. In the disclosed embodiment, the solution that can maximize the improvement of the indoor heating effect is to reduce the upper limit operating frequency of the air conditioner compressor and reduce the outer pipe judgment temperature of the air conditioner according to the frequency of defrosting to obtain the target operating parameters.

[0070] By lowering the temperature of the outer pipe of the air conditioner according to the frequency of defrosting, the temperature of the outer pipe when the air conditioner enters the defrost mode can be lowered, thereby reducing the frequency of defrosting of the air conditioner.

[0071] In one possible approach, Figure 2 As shown, according to the frequency of defrosting, lowering the outer pipe judgment temperature of the air conditioner may include:

[0072] When the defrosting frequency is greater than or equal to the first threshold, the outer pipe judgment temperature of the air conditioner is subtracted from the first preset temperature value;

[0073] When the defrosting frequency is less than the first threshold and greater than or equal to the second threshold, the outer pipe temperature of the air conditioner is subtracted from a second preset temperature value, wherein the second preset temperature value is less than the first preset temperature value.

[0074] It should be understood that by making different adjustments to the outer tube judgment temperature in different situations according to the value of the defrost frequency, the air conditioner can be controlled more finely according to the defrost frequency. The disclosed embodiment divides the value of the defrost frequency into two intervals. Of course, the intervals of the value of the defrost frequency can also be divided more finely for better fine control. When the defrost frequency is large, exceeding the first threshold, the outer tube judgment temperature is reduced by a larger preset temperature value (i.e., the first preset temperature value). When the defrost frequency is large, but does not exceed the first threshold, but only exceeds the second threshold, the outer tube judgment temperature is reduced by a smaller preset temperature value (i.e., the second preset temperature value). When the defrost frequency is small, less than the second threshold, the outer tube judgment temperature can maintain the status quo. In the above manner, fine adjustment of the outer tube judgment temperature can be achieved.

[0075] For example, the first preset temperature value may be any of the following values: 1°C, 1.5°C, 2°C, 2.5°C, preferably 2°C. The second preset temperature value may be any of the following values: 2°C, 3°C, 4°C, 5°C, preferably 4°C.

[0076] By adjusting the outer tube to determine the temperature, the operating parameters of the air conditioner can be finely adjusted, thereby reducing the frequency of defrosting the air conditioner.

[0077] In one possible approach, Figure 2 As shown, step S101 may include:

[0078] Determine the number of defrosts and the power-on time during the current operation of the air conditioner;

[0079] The result of dividing the number of defrost times by the power-on time is determined as the defrost frequency during the current operation of the air conditioner.

[0080] It should be understood that there are many ways to determine the defrost frequency during the current operation of the air conditioner by dividing the number of defrost times by the power-on time. Two methods are provided in the embodiments of the present disclosure.

[0081] For example, suppose the air conditioner runs for 10 hours and defrosts 20 times during this period. During this operation of the air conditioner, the defrost frequency = 20 / 10 = 2 times / hour, and step S102 can be directly executed according to the result of dividing the number of defrosts by the power-on time. The defrost frequency can also be normalized and scaled to a range of 0 to 1. For example, the defrost frequency is divided by the preset upper limit of the defrost frequency: the normalized result = defrost frequency / preset upper limit of the defrost frequency. Assuming that the preset upper limit of the defrost frequency is 3 (i.e., 3 defrosts within 1 hour), the normalized result = 2 / 3 = 0.67.

[0082] In addition, it should be understood that the current defrost frequency is obtained by dividing the current defrost times by the current power-on time, making the frequency measurement and calculation simpler and more intuitive. The normalization process: 1) can limit the comparison range of defrost frequency to between 0 and 1, making it easier to compare the defrost conditions of different air conditioners, better understand the defrost conditions of the air conditioner during the entire operation process, and help with maintenance and adjustment; 2) can also better understand the true distribution of the data. If the upper limit of the defrost frequency is 3, it can be seen that the defrost condition of the air conditioner is better than the upper limit, and the degree of optimization can be more intuitively seen.

[0083] In one possible manner, step S101 may include:

[0084] Determine the defrosting time and the power-on time of the air conditioner during this operation;

[0085] The result of dividing the defrost time by the power-on time is determined as the defrost frequency during the current operation of the air conditioner.

[0086] It should be understood that both the defrost time and the number of defrosts can characterize the defrost situation within the power-on time. The present disclosure provides two embodiments, among which the one that best characterizes the defrost frequency is to determine the defrost frequency during the current operation of the air conditioner by dividing the number of defrosts by the power-on time. If the defrost frequency during the current operation of the air conditioner is determined by dividing the defrost time by the power-on time. Correspondingly, the first threshold and the second threshold of the above-mentioned defrost frequency should also be adaptively adjusted in the form of a ratio of the defrost time to the power-on time, such as 0.1 and 0.15. There are many ways to determine the defrost frequency during the current operation of the air conditioner by dividing the defrost time by the power-on time, and two methods are provided in the embodiments of the present disclosure.

[0087] For example, suppose the air conditioner runs for 10 hours and defrosts for 1 hour. During this operation of the air conditioner, the defrost frequency = 1 / 10 = 0.1, and step S102 can be directly executed according to the result of dividing the defrost time by the power-on time. The defrost frequency can also be normalized and scaled to a range of 0 to 1. For example, the defrost frequency is divided by the preset upper limit of the defrost frequency: the normalized result = defrost frequency / preset upper limit of the defrost frequency. Assuming that the preset upper limit of the defrost frequency is 0.2 (that is, the defrost time accounts for one-fifth of the current operation time of the air conditioner), the normalized result = 0.1 / 0.2 = 0.5.

[0088] By using any of the above air conditioning control methods, the frequency of air conditioning defrosting can be reduced, while taking defrosting into account, the indoor heating effect can be better improved and the user experience can be enhanced; at the same time, the above solution does not require hardware modification, has low cost, strong versatility, and is suitable for most air conditioners.
