An embodiment of the present invention provides an air conditioner fin defrosting method, which is applied to an air conditioner, and the air conditioner fin of the air conditioner has a shape memory function. The air conditioner fin is made of a memory alloy, and the memory alloy can be a nickel-titanium alloy, and its phase change temperature range is -15°C to 5°C, and it can achieve an automatic defrosting function through the shape memory effect. Specifically, when the air conditioner fin made of the memory alloy (hereinafter referred to as the air conditioner fin or the memory alloy air conditioner fin) is heated to a temperature higher than the phase change temperature, it will restore the preset shape through the shape memory effect. This controlled deformation can generate sufficient mechanical force to destroy and peel off the frost layer on its surface.

[0052] like Figure 1 As shown, the method includes the following steps S100-S400.

[0053] S100: Determine whether the air conditioner fins need to be defrosted.

[0054] In this embodiment, the judgment process mainly relies on the coordinated work of the temperature sensor and the humidity sensor. The temperature sensor monitors the change of the ambient temperature in real time, and the humidity sensor continuously tracks the change of the ambient humidity. The combination of the two can accurately identify the environmental conditions that may cause frost. When the environmental conditions continue to operate for a period of time, it means that the frost layer has accumulated to a certain extent, and it is determined that a defrosting operation is required.

[0055] In other embodiments, whether defrosting is required is determined by image recognition: a miniature camera is installed in the air-conditioning fin area of ​​the air-conditioning outdoor unit to collect image data of the surface of the air-conditioning fin; an image processing algorithm is used to analyze the reflective characteristics and texture characteristics of the surface of the air-conditioning fin. When obvious frost characteristics (such as changes in reflectivity, blurred surface texture, etc.) are detected on the surface of the air-conditioning fin; combined with a deep learning algorithm, the degree of frost coverage (including area and thickness) in the image is identified through a pre-trained neural network model. When the degree of coverage exceeds a preset threshold (for example, 30%), it is determined that a defrosting operation is required. Here, the degree of coverage exceeding the preset threshold means that the coverage area and the coverage thickness exceed the preset threshold respectively.

[0056] S200: When defrosting is required, determine target deformation parameters of the air conditioner fins.

[0057] In this embodiment, when it is determined that defrosting is required, the target deformation parameters of the air conditioner fins are determined according to the current frost layer state. The target deformation parameters include the deformation amount and deformation rate that the air conditioner fins need to achieve, which directly affect the effect and efficiency of defrosting. The determination process of the target deformation parameters comprehensively considers factors such as frost layer thickness and hardness.

[0058] In this embodiment, the deformation refers to the degree of deformation of the air conditioner fin during the defrosting process, which can be expressed by the displacement size: the maximum displacement distance of the air conditioner fin from the initial state to the deformed state, in millimeters (mm). The deformation rate indicates how fast the deformation of the air conditioner fin occurs, that is, the change in deformation per unit time, which can be expressed by the displacement rate: the displacement change per second, in millimeters / second (mm / s).

[0059] The deformation amount determines whether sufficient mechanical force can be generated to destroy and peel off the frost layer; the deformation rate affects the defrosting efficiency and the stress impact on the air conditioner fins. Too fast a deformation rate may damage the air conditioner fins, while too slow a deformation rate may affect the defrosting efficiency. Therefore, in practical applications, these two parameters need to be controlled according to the characteristics of the frost layer to achieve the best defrosting effect.

[0060] S300, controlling a heating device to heat the air conditioner fins according to a target deformation parameter, so that the air conditioner fins are deformed to achieve defrosting.

[0061] In this embodiment, after the target deformation parameters are determined, the operation of the heating device is controlled according to these parameters. The heating device can be an electric heater or other heating element, and the air conditioner fins can produce the expected deformation by adjusting the heating power and time. During the heating process, the air conditioner fins will gradually change from the initial state to a preset arc or corrugated shape, and this deformation can effectively destroy and peel off the frost layer.

[0062] In this embodiment, the initial state of the air conditioner fin is a corrugated design, and the heating device is controlled to transform the original corrugated shape into a tighter pleated shape. This change in the corrugation spacing generates sufficient mechanical force to effectively remove the frost layer.

[0063] S400, monitoring the defrosting effect and dynamically adjusting the control parameters of the heating device according to the monitoring result until the preset defrosting effect is achieved.

[0064] In this embodiment, during the defrosting process, the defrosting effect is continuously monitored. The monitoring content includes the actual deformation amount, actual deformation rate, frost layer shedding condition, etc. of the air conditioner fins. According to the monitoring results, the control parameters of the heating device, such as heating power, heating time, etc., can be adjusted in real time to ensure that the defrosting process always remains in the optimal state. This dynamic adjustment mechanism continues until the preset defrosting effect is achieved. The preset defrosting effect here can restore the pressure on the surface of the air conditioner fins to more than 90% of the initial value, indicating that the frost layer has basically fallen off.

[0065] In this embodiment, it is ensured that the defrost process always remains in the optimal state. The optimal state here specifically refers to: the control parameters of the heating device (heating power, heating time) can ensure that the defrost process can approach or achieve the expected effect without causing excessive stress on the air-conditioning fins.

[0066] It can be seen that, through steps S100-S400 of the embodiment of the present invention, the air-conditioning fins with shape memory function are heated with target deformation parameters controlled, so that the air-conditioning fins produce controlled deformation to mechanically break the frost layer, thereby avoiding the high energy consumption problem of traditional electric heating defrosting that requires completely melting the frost layer. By monitoring the defrosting effect and dynamically adjusting the control parameters until the preset effect is achieved, a precise and controllable defrosting process is achieved, and at the same time, the technical problem that the traditional defrosting method requires interrupting the operation of the air conditioner is solved.

[0067] In one embodiment, S100, determining whether the air conditioner fins need to be defrosted, includes: S101, monitoring the ambient temperature and ambient humidity of the air conditioner fins; S102, when the ambient temperature is lower than a preset temperature threshold and the ambient humidity is higher than a preset humidity threshold for a period of time exceeding a preset time, determining that defrosting is required.

[0068] In this embodiment, when determining whether the air conditioner fins need to be defrosted, the decision is mainly made by monitoring two parameters: ambient temperature and ambient humidity.

[0069] Temperature monitoring uses high-precision PT100 platinum resistance temperature sensors. Multiple temperature sensors are evenly distributed around the air conditioner fins to ensure that local temperature changes can be accurately captured. The preset temperature threshold is set to -15℃.

[0070] Humidity monitoring uses the HIH-4000 series capacitive humidity sensor with a measurement range of 0-100% relative humidity. The preset humidity threshold is set at 70% relative humidity. When the ambient humidity exceeds this threshold, the risk of frost increases significantly.

[0071] When the ambient temperature is below -15℃ and the relative humidity is above 70% for a period of time exceeding the preset time (e.g. 30 minutes), it indicates that frost has formed on the fin surface of the air conditioner and accumulated to a certain extent, and the defrosting procedure needs to be started. This dual judgment mechanism can effectively avoid misjudgment and improve the accuracy and timeliness of defrosting control.

[0072] In one embodiment, the target deformation parameters include a target deformation amount and a target deformation rate; in S200, the target deformation parameters of the air-conditioning fins are determined, including: S201, obtaining the target frost layer characteristic parameters of the air-conditioning fins; S202, determining the target deformation amount and target deformation rate corresponding to the target frost layer characteristic parameters according to the corresponding relationship between the preset frost layer characteristic parameters and the deformation parameters.

[0073] In this embodiment, when determining the target deformation parameters of the air conditioner fins, it is necessary to determine the target deformation amount and the target deformation rate respectively. The specific implementation process is as follows:

[0074] First, the target frost layer characteristic parameters on the air conditioner fins are obtained through sensors. This parameter reflects the physical characteristics of the frost layer and is the basis for determining the target deformation parameters. By finding the corresponding relationship between the preset frost layer characteristic parameters and the deformation parameters, the target frost layer characteristic parameters can be mapped to the optimal target deformation amount and target deformation rate.

[0075] The correspondence between the preset frost layer characteristic parameters and deformation parameters is a mapping table established through a large amount of experimental data, which contains the optimal deformation parameters under different frost layer conditions. For example, when slight frost is detected (frost layer thickness is less than 1mm), a smaller target deformation amount and a slower target deformation rate are selected. When severe frost is detected (frost layer thickness is greater than 3mm), the target deformation amount and target deformation rate are increased accordingly.

[0076] This dynamic parameter determination mechanism based on frost layer characteristics can ensure that the defrosting process can approach or achieve the expected effect without causing excessive stress on the air-conditioning fins, thereby extending the service life of the air-conditioning fins.

[0077] In one embodiment, the target frost layer characteristic parameters include a frost layer thickness parameter and a frost layer hardness parameter; S201, obtaining the target frost layer characteristic parameters of the air-conditioning fin, including: S2011, obtaining the frost layer thickness parameter according to the pressure exerted by the frost layer on the surface of the air-conditioning fin; S2012, obtaining the frost layer hardness parameter according to the frost layer thickness parameter, the ambient temperature of the air-conditioning fin and the frost layer formation time.

[0078] In this embodiment, S2011, obtaining the frost layer thickness parameter according to the pressure exerted by the frost layer on the surface of the air-conditioning fin, specifically includes: setting multiple pressure sensors on the surface of the air-conditioning fin to form a measurement array; collecting the pressure value detected by the pressure sensor; calculating the frost layer thickness parameter according to the following empirical formula: h=k×P+b, wherein h represents the frost layer thickness, in mm; P represents the detected pressure value, in kPa; k is the proportional coefficient, and b is the correction constant.

[0079] S2012. Obtain frost layer hardness parameters according to frost layer thickness parameters, ambient temperature of air-conditioning fins and frost layer formation time, specifically including: obtaining real-time ambient temperature and frost layer formation time of air-conditioning fins; calculating frost layer hardness parameters according to the following empirical formula: H=floor(α×h+β×t+γ×(1 / |T-(-15)|)), wherein H represents frost layer hardness value; h represents frost layer thickness, in mm; t represents frost layer formation time, in min; T represents ambient temperature, in °C; α represents thickness influence coefficient, β represents time influence coefficient, and γ represents temperature influence coefficient; floor() represents rounding down.

[0080] In this embodiment, the frost formation time refers to the cumulative time from when the ambient temperature first drops below -15°C and the relative humidity first rises above 70% to when the defrost operation begins, during which the ambient temperature continues to be below -15°C and the relative humidity continues to be above 70%.

[0081] In a specific embodiment, when obtaining the target frost layer characteristic parameters of the air conditioner fin, it is necessary to determine the frost layer thickness parameter and the frost layer hardness parameter respectively. This embodiment provides a step of detecting the frost layer thickness parameter based on pressure and obtaining the frost layer hardness parameter based on the frost layer thickness parameter and other parameters.

[0082] First, when obtaining the frost thickness parameters, a strain gauge pressure sensor model MPX5700 is used to monitor the pressure on the surface of the air conditioner fin in real time. The pressure sensor is arranged in an array, with multiple measuring points evenly distributed on the surface of the air conditioner fin. As the thickness of the frost layer increases, the pressure of the frost layer on the surface of the air conditioner fin will gradually increase. The frost thickness parameter is determined by the pre-established correspondence between the pressure and the frost layer thickness. Specifically, there is the following empirical formula between the frost layer thickness and the pressure value: h = k × P + b, where the proportional coefficient k and the correction constant b can be obtained through experiments.

[0083] Secondly, during the formation process of the frost layer, there is a certain correspondence between its hardness and the frost layer thickness, ambient temperature, and formation time. When determining the frost layer hardness parameters, a reliable estimation of the frost layer hardness can be achieved through the mapping relationship between these parameters established in advance.

[0084] Specifically, the frost hardness (H) is related to the following parameters: h represents the frost thickness (mm), t represents the frost formation time (min), and T represents the ambient temperature (°C). There is the following empirical formula: H = floor (α×h+β×t+γ×(1 / |T-(-15)|)). Among them, |T-(-15)| represents the absolute value of the difference between the ambient temperature and -15°C. The coefficients α, β, and γ here can be obtained through experiments.

[0085] In a more specific embodiment, the proportionality coefficient k and the correction constant b in the empirical formula between frost thickness and pressure: h = k × P + b can be obtained in the laboratory through the following process: In the laboratory environment, by controlling the temperature at about -15°C and the relative humidity above 70%, the frost growth experiment is carried out using the air conditioner fin. The calibration of the frost thickness uses a precision laser rangefinder as a reference, and the output value of the pressure sensor located on the surface of the air conditioner fin is recorded at the same time. The specific experimental process is as follows:

[0086] In a temperature and humidity controlled laboratory, an air-conditioning fin sample of standard specifications was used, and 9 pressure sensors were evenly arranged on the surface of the air-conditioning fin to form a 3×3 measurement array.

[0087] A set of experimental data was recorded every 30 minutes; each set of experimental data included: pressure values ​​at 9 measuring points and frost thickness values ​​at corresponding positions; the data was recorded continuously for 8 hours, and a total of 16 sets of data were obtained; the experiment was repeated 3 times to ensure the reliability of the experimental data.

[0088] Calculate the average pressure value P_avg of the 9 measurement points in each set of data; calculate the corresponding average thickness of the frost layer h_avg; plot the data points in the coordinate system, with the horizontal axis being the pressure value (kPa) and the vertical axis being the thickness value (mm). Use the least squares method to perform linear fitting on the experimental data to obtain specific k and b values.

[0089] The advantages of this calibration method are: the experimental conditions are controllable and the experimental data are reliable; it has good repeatability and is easy to reproduce in other laboratories; it takes into account the average effect of multi-point measurement and improves accuracy; it is easy to verify the applicability of the empirical formula under different working conditions. This calibration method provides a reliable parameter basis for engineering practice, making the online monitoring of frost thickness have good accuracy and reliability.

[0090] In a more specific embodiment, the influence coefficients in the empirical formula between frost layer hardness and frost layer thickness, ambient temperature, and formation time can be obtained in the laboratory through the following process: In a laboratory environment with controlled temperature and humidity, a standard air conditioning fin sample is used to test the frost layer hardness. In order to ensure the comprehensiveness and reliability of the experimental data, a multi-factor orthogonal experimental method is used to study the three main influencing factors of frost layer hardness. The experimental design includes the following main variables: frost layer thickness range: 0.5-5mm, every 1mm is a test point; ambient temperature range: -20℃ to -10℃, every 5℃ is a test point; frost time range: 30-240 minutes, every 30 minutes is a test point.

[0091] Under each working condition, the following measurements were performed: the hardness value of 5 different positions on the frost layer surface was measured using a hardness tester; the current frost layer thickness, ambient temperature and frosting time were recorded; each group of working conditions was tested three times and the average value was taken. The values ​​of the influence coefficients α, β and γ were determined through multivariate linear regression analysis.

[0092] The advantages of this experimental method are strong systematicity and good repeatability, which provides a reliable parameter basis for engineering practice. The influence coefficient obtained by this method can better reflect the quantitative relationship between the frost layer hardness and various influencing factors.

[0093] In other embodiments, in obtaining the target frost layer characteristic parameters of the air-conditioning fins, the frost layer thickness parameters can also be calculated based on the change in ambient humidity before and after the air-conditioning fins are frosted. The specific measurement needs to be performed in a specific area around the air-conditioning fins to ensure the accuracy of the calculation. The principle of this calculation method for calculating the frost layer thickness by the change in ambient humidity is based on thermodynamics and phase change principles. Specifically, under certain temperature and pressure conditions, the amount of water vapor that can be contained in the air is limited. When the saturation state is reached, the excess water vapor will condense into frost. By monitoring the changes in ambient humidity of the air near the surface of the air-conditioning fins before and after frosting, combined with the ideal gas state equation and the definition of relative humidity, the amount of water vapor condensed into frost can be calculated, and then the thickness of the frost layer on the surface of the air-conditioning fins can be roughly estimated. This embodiment calculates the frost layer thickness parameters by monitoring the changes in ambient humidity before and after the air-conditioning fins are frosted, which can be used as a contactless frost layer detection method.

[0094] In one embodiment, S300, controlling the heating device to heat the air-conditioning fins according to the target deformation parameters, so that the air-conditioning fins are deformed to achieve defrosting, including: S301, determining the heating power and heating time of the heating device according to the target deformation parameters; S302, controlling the heating device to heat the air-conditioning fins according to the heating power within the heating time, so that the air-conditioning fins are deformed to achieve defrosting.

[0095] In this embodiment, when the heating device is controlled to defrost according to the determined target deformation parameter, the heating power and heating time need to be calculated and controlled. In the actual implementation process, the heating power is first determined according to the target deformation rate, and the heating time is determined according to the target deformation amount.

[0096] The calculation of heating power needs to take into account the phase change characteristics of the air conditioner fins containing memory alloy material and the influence of ambient temperature. The heat Q required for the memory alloy air conditioner fin to rise from the initial temperature T0 to the phase change temperature Tt can be calculated by the following formula: Q = m × c × (Tt-T0), where m is the mass of the memory alloy and c is the specific heat capacity of the memory alloy. Taking into account the heat dissipation loss, the actual required heat should be increased by about 30% on the basis of the theoretical value. Therefore, the heating power P can be expressed as: P = k × Q / t, where k is the compensation coefficient and t is the target time to reach the phase change temperature. The target time t is inversely proportional to the target deformation rate V, which can be expressed as: t = α / V, where α is the proportionality coefficient, obtained through experimental calibration.

[0097] The determination of heating time mainly depends on the target deformation D. When the memory alloy air conditioner fin reaches the phase transition temperature, the deformation gradually increases with the heating time until it reaches the target value. According to the experimental data fitting, the deformation and heating time are approximately linearly related: T = β × D, where T is the required heating time and β is the proportional coefficient calibrated by the experiment. To ensure sufficient and stable deformation, the actual heating time should be appropriately extended by 10-15% based on the theoretical value.

[0098] In the actual control process, the heating power is dynamically adjusted according to the real-time temperature of the memory alloy air-conditioning fins fed back by the temperature sensor, and the heating time is corrected in real time according to the actual deformation fed back by the displacement sensor, so as to ensure the defrosting effect.

[0099] In this embodiment, the heating device includes electric heating wires evenly distributed on the surface of the air conditioner fins. In other embodiments, other heating devices can be used as long as the control of heating power and heating time can be achieved.

[0100] In one embodiment, S400, monitoring the defrosting effect and dynamically adjusting the control parameters of the heating device according to the monitoring result until a preset defrosting effect is achieved, includes: performing the following steps according to a preset sampling time interval:

[0101] S401. Obtain the actual deformation amount and actual deformation rate of the air-conditioning fins; S402. Calculate a first deviation value between the actual deformation amount and the target deformation amount, and a second deviation value between the actual deformation rate and the target deformation rate; S403. When the first deviation value exceeds the first preset range or the second deviation value exceeds the second preset range, adjust the heating power and / or heating time of the heating device accordingly; S404. Determine whether the defrost completion conditions are met. When the defrost completion conditions are met, stop the heating of the heating device and control the shape of the air-conditioning fins to return to the initial state.

[0102] In this embodiment, the defrosting process is controlled by establishing a defrosting effect monitoring and dynamic adjustment mechanism. A monitoring and adjustment cycle is performed at a preset sampling time interval (for example, every 30 seconds). The specific implementation process is as follows:

[0103] Obtaining actual deformation parameters: A linear displacement sensor is used to monitor the actual deformation state of the air conditioner fins in real time. The displacement sensor sets multiple measurement points on the surface of the air conditioner fins, and calculates the actual deformation and actual deformation rate of the air conditioner fins through a data fusion algorithm. For example, when the displacement values ​​of the three measurement points are detected to be 2.5mm, 2.3mm, and 2.4mm respectively, the actual deformation is 2.4mm through weighted average. By collecting displacement data every 5s, the difference in deformation between adjacent sampling moments is calculated and divided by the time interval to obtain the actual deformation rate.

[0104] Deviation calculation and evaluation: Calculate the first deviation value between the actual deformation and the target deformation, and the second deviation value between the actual deformation rate and the target deformation rate. The specific calculation formula is: first deviation value = |actual deformation - target deformation | / target deformation × 100%; second deviation value = |actual deformation rate - target deformation rate | / target deformation rate × 100%.

[0105] The first preset range is set to ±5%, and the second preset range is set to ±10%. When any deviation value exceeds its preset range, the dynamic adjustment mechanism of the control parameter is triggered.

[0106] Dynamic adjustment of control parameters: According to the size and direction of the deviation value, the fuzzy control algorithm is used to adjust the control parameters of the heating device: When the first deviation value is positive and exceeds the range (the actual deformation is too large), the heating power is reduced by 15%-20%, or the heating time is shortened by 2-3 seconds. When the first deviation value is negative and exceeds the range (the actual deformation is insufficient), the heating power is increased by 15%-20%, or the heating time is extended by 2-3 seconds. When the second deviation value is out of range, the heating power is mainly adjusted to achieve control of the deformation rate. For example, when the actual deformation rate is too fast, the heating power is appropriately reduced.

[0107] Defrosting completion judgment: Determine whether defrosting is completed by comprehensively analyzing multiple parameters. Specific judgment conditions include: Environmental parameter indicators: The ambient temperature rises to above -10°C and the relative humidity drops to below 65%. Air conditioner fin status indicator: The surface pressure of the air conditioner fin recovers to more than 90% of the initial value, indicating that the frost layer has basically fallen off.

[0108] When any of the above two conditions is met and remains stable for more than 1 minute, the defrosting is considered complete. Subsequently, the operation of the heating device is stopped and the air conditioner fins are smoothly restored to their initial state. This defrosting solution based on multi-parameter closed-loop control improves the controllability and reliability of the defrosting process.

[0109] In one embodiment, S300, controlling the heating device to heat the air-conditioning fins according to the target deformation parameters so that the air-conditioning fins are deformed to achieve defrosting, the method further includes: S303, when the change in the environmental parameters is greater than the preset change, adjusting the control parameters of the heating device accordingly.

[0110] In this embodiment, the environmental parameters include environmental temperature and environmental humidity. S303, when the change in the environmental parameters is greater than the preset change, the control parameters of the heating device are adjusted accordingly, specifically including: monitoring the changes in the environmental temperature and environmental humidity of the air conditioner fins;

[0111] When the change in ambient temperature is greater than the first preset change, the first parameter adjustment strategy is executed: for example, if the ambient temperature rises by more than 3°C / 5 minutes, the heating power of the heating device is reduced by 15%-20%, and the heating time is shortened by 2-3 minutes; if the ambient temperature drops by more than 3°C / 5 minutes, the heating power of the heating device is increased by 20%-25%, and the heating time is extended by 3-4 minutes;

[0112] When the change in ambient humidity is greater than the second preset change, the second parameter adjustment strategy is executed: for example, if the relative humidity changes by more than 10% within 5 minutes, the heating duration of the heating device is adjusted accordingly. When the ambient humidity increases by more than 10% / 5min: the heating duration is extended (for example, from the original 3 minutes to 4-5 minutes); when the ambient humidity decreases by more than 10% / 5min: the heating duration is shortened (for example, from the original 3 minutes to 2 minutes).

[0113] In a specific embodiment, by real-time monitoring of the changing trend of environmental parameters, the control strategy of the heating device is intelligently adjusted to ensure the stability of the defrosting effect.

[0114] The monitoring of environmental parameters mainly includes the following aspects:

[0115] Temperature change monitoring: PT100 temperature sensor is used to continuously monitor the change of ambient temperature. When the ambient temperature rises by more than 3°C within 5 minutes, it is considered a significant temperature rise; when the temperature drops by more than 3°C within 5 minutes, it is considered a significant temperature drop.

[0116] Humidity change monitoring: HIH-4000 series humidity sensors are used to monitor changes in ambient humidity. When the ambient humidity increases by more than 10% / 5min or when the ambient humidity decreases by more than 10% / 5min, it is considered a significant humidity change.

[0117] According to the changes in different environmental parameters, adopt corresponding control parameter adjustment strategies:

[0118] When the ambient temperature rises significantly, the heating power is reduced by 15-20% and the heating time is shortened by 2-3 minutes. A higher ambient temperature helps the frost layer to melt naturally, so the defrosting intensity can be appropriately reduced.

[0119] When the ambient temperature drops significantly, increase the heating power by 20-25% and extend the heating time by 3-4 minutes. Lower ambient temperatures are conducive to the formation of frost, so the defrosting intensity can be appropriately increased.

[0120] When the ambient humidity changes significantly, the duration of heating is mainly adjusted. For example, when the humidity increases, the duration of heating is extended to prevent the frost layer from re-forming quickly. On the contrary, when the humidity decreases, the duration of heating is shortened to save energy consumption. This embodiment can maintain the best defrosting effect under different environmental conditions by responding to changes in environmental parameters in real time and dynamically adjusting control parameters.

[0121] Figure 8 A schematic block diagram of an air conditioner fin defrosting device provided by an embodiment of the present invention; Fig. 9 Schematic block diagram of an air conditioner provided by an embodiment of the present invention. Figure 8 As shown, corresponding to the above air conditioner fin defrosting method, the embodiment of the present invention also provides an air conditioner fin defrosting device 500, which is deployed in Fig. 9 In the air conditioner 600 shown, the air conditioner fins of the air conditioner 600 have a shape memory function, and the air conditioner fin defrost device 500 includes: a defrost judgment unit 501, used to judge whether the air conditioner fins need to be defrosted; a target deformation parameter determination unit 502, used to determine the target deformation parameters of the air conditioner fins when defrosting is required; a deformation control unit 503, used to control the heating device to heat the air conditioner fins according to the target deformation parameters, so that the air conditioner fins are deformed to achieve defrosting; a monitoring control unit 504, used to monitor the defrosting effect and dynamically adjust the control parameters of the heating device according to the monitoring results until the preset defrosting effect is achieved.

[0122] In this embodiment, the defrost judgment unit 501 collects environmental parameters and comprehensively judges whether it is necessary to start the defrost program. The judgment process of the defrost judgment unit 501 mainly relies on the coordinated work of the temperature sensor and the humidity sensor. The temperature sensor monitors the changes in the ambient temperature in real time, and the humidity sensor continuously tracks the changes in the ambient humidity. The two can be used together to accurately identify the environmental conditions that may cause frost. When the environmental conditions continue to run for a period of time, it means that the frost layer accumulates to a certain extent, and it is determined that a defrost operation is required.

[0123] When it is determined that defrosting is required, the target deformation parameter determination unit 502 determines the target deformation parameters of the air conditioner fins according to the current frost layer state. The target deformation parameters include the deformation amount and deformation rate that the air conditioner fins need to achieve, which directly affect the effect and efficiency of defrosting. The determination process of the target deformation parameters comprehensively considers factors such as frost layer thickness and hardness.

[0124] After determining the target deformation parameters, the deformation control unit 503 controls the operation of the heating device according to these parameters. The heating device can be an electric heater or other heating element, and the air conditioner fins can produce the expected deformation by adjusting the heating power and time. During the heating process, the air conditioner fins will gradually change from the initial state to a preset arc or corrugated shape, and this deformation can effectively destroy and peel off the frost layer.

[0125] During the defrosting process, the monitoring control unit 504 is responsible for continuously monitoring the defrosting effect. The monitoring content includes the actual deformation amount, deformation rate, frost shedding of the air conditioner fins, etc. According to the monitoring results, the control parameters of the heating device, such as heating power, heating time, etc., can be adjusted in real time to ensure that the defrosting process is always maintained in the optimal state. This dynamic adjustment mechanism continues until the preset defrosting effect is achieved.

[0126] The above functional units form a complete defrosting device through data exchange and collaborative work. The device can adaptively adjust the control parameters according to environmental changes and defrosting needs to achieve efficient and energy-saving defrosting functions. This defrosting device based on the shape memory function and intelligent control of air-conditioning fins has the following advantages over traditional defrosting methods: it uses the shape memory effect to achieve active defrosting without changing the refrigerant flow direction; it ensures the defrosting effect through parameter control and avoids energy waste caused by excessive heating.
