Description

[0002] With the diversification of air conditioner application scenarios and the improvement of user requirements, there are some deficiencies in the fins of traditional air conditioner heat exchangers.

[0003] For the indoor unit heat exchanger, in the cooling condition, a high-humidity environment will cause a condensate water film to form on the surface of the fins, hindering air flow and heat transfer, and reducing the cooling efficiency; in the heating condition, the cold air has poor fluidity, and the traditional fins cannot effectively improve air flow, resulting in insufficient heat exchange and affecting the heating effect.

[0004] For the outdoor unit heat exchanger, in the cooling mode, a high-temperature environment or long-term operation will cause the temperature of the outdoor unit to rise, and the heat dissipation efficiency of the traditional fins will decrease significantly as the air boundary layer thickens and the thermal resistance increases; in the heating mode, when the temperature of the outdoor unit decreases in a cold environment, the traditional fins are difficult to effectively absorb heat from the low-temperature air, affecting the overall heating performance.

[0058] Please refer to Figure 1 , the air conditioner control method provided by the embodiment of the present invention is applied to an air conditioner. The air conditioner includes an indoor unit fin with a shape memory function and an outdoor unit fin with a shape memory function. The indoor unit fin can be in a first original form, a curled deformation form or a micro-rib heightening form according to the current indoor unit ambient temperature, and the outdoor unit fin can be in a second original form, a shrinkage deformation form or an expansion deformation form according to the current outdoor unit ambient temperature. The method includes the following steps S100 - S300:

[0059] S100. Obtain the current indoor unit ambient temperature and the current outdoor unit ambient temperature.

[0060] In this embodiment, the air conditioner monitors the ambient temperatures of the indoor unit and the outdoor unit in real time through temperature sensors, provides basic data for subsequent adjustment of other operating parameters (such as compressor frequency, fan speed, etc.), and is used to determine the current states of the indoor unit fin and the outdoor unit fin. These temperature data reflect the actual working environments of the indoor and outdoor unit fins during the operation of the air conditioner.

[0061] S200. Determine the first current form of the indoor unit fin according to the current indoor unit ambient temperature, and determine the second current form of the outdoor unit fin according to the current outdoor unit ambient temperature.

[0062] In this embodiment, the air conditioner judges the current forms of the indoor and outdoor unit fins according to the acquired temperature data. The shape memory alloy fins will automatically deform according to the ambient temperature, and the form conversion can be achieved without additional control. The air conditioner confirms that the fins have reached the corresponding forms through temperature monitoring, providing a basis for subsequent parameter adjustment.

[0063] S300. Adjust the operating parameters of the air conditioner according to the first current form and the second current form.

[0064] In this embodiment, when the air conditioner detects a change in the fin form, it can correspondingly adjust the operating parameters of the air conditioner, such as compressor frequency, fan speed, etc., to match the heat exchange characteristics in the new fin form and ensure the efficient operation of the air conditioner system.

[0065] In this embodiment, the fins of both the indoor and outdoor units of the air conditioner are made of shape memory alloy. Shape memory alloy is a material with a specific phase change temperature range, capable of undergoing predictable shape changes under different temperature conditions. The fins in this embodiment can automatically switch between different forms according to the ambient temperature:

[0066] The indoor unit fins have three forms: The first original form: the basic shape when the temperature is within the normal range, and the fins are in a straight state; the curled deformation form: when the temperature drops below a specific threshold, the edges of the fins curl upward, helping to prevent the formation of a continuous water film of condensate; the micro-rib heightening form: when the temperature rises above a specific threshold, the fins become straighter, the spacing decreases, and the height of the micro-ribs increases, forming stronger turbulence and enhancing heat exchange.

[0067] The outdoor unit fins have three forms: The second original form: the basic shape when the temperature is within the normal range; the shrinkage deformation form: when the temperature drops below a specific threshold, the fins as a whole shrink, more effectively absorbing heat from the low-temperature air; the expansion deformation form: when the temperature rises above a specific threshold, the fins expand or twist from a plane to three dimensions, breaking the air boundary layer and forming turbulence, improving the heat dissipation efficiency.

[0068] In this embodiment, the air conditioner control method solves the problems of traditional air conditioner heat exchangers under different working conditions:

[0069] For the indoor unit fins:

[0070] In the cooling mode, when the ambient temperature drops below a specific threshold, the indoor unit fins automatically transform into the curled deformation form, making it easier for the condensate to flow down and form water droplets instead of a continuous water film, reducing the thermal resistance and improving the heat exchange efficiency;

[0071] In the heating mode, when the ambient temperature rises above a specific threshold, the indoor unit fins automatically transform into the micro-rib heightening form, enhancing the air turbulence and improving the heat exchange between the cold air and the fins by reducing the fin spacing and increasing the micro-rib height

[0072] For the outdoor unit fins:

[0073] In the cooling mode, when the ambient temperature rises above a specific threshold, the outdoor unit fins automatically transform into the expansion deformation form, breaking the air boundary layer, increasing the turbulence, and improving the heat dissipation efficiency;

[0074] In the heating mode, when the ambient temperature drops below a specific threshold, the outdoor unit fins automatically transform into the shrinkage deformation form, coming into contact with the low-temperature air more effectively and improving the heat absorption efficiency.

[0075] Meanwhile, the air conditioner adjusts the operating parameters according to the fin form, enabling the air conditioner to make full use of the improvement in heat exchange efficiency brought about by the fin form change and achieving energy conservation or performance enhancement.

[0076] The air conditioner control method provided in this embodiment enables the air conditioner to intelligently adapt to different working conditions by applying the temperature response characteristics of shape memory alloy fins, automatically optimize the heat exchange efficiency under different temperature conditions, solve the efficiency problems of traditional air conditioner heat exchangers in cooling and heating modes, improve the overall performance of the air conditioner system, extend the equipment life, and reduce energy consumption.

[0077] In this embodiment, when the temperature rises above a specific threshold, the inner machine fins will deform into a micro-rib heightening form. At this time, the distance (spacing) between adjacent fins will decrease, making the channel through which air flows between the fins narrower. This process of spacing reduction usually progresses gradually from both ends of the fins towards the middle, ensuring the stability of air flow.

[0078] After the spacing decreases, the air is forced to flow in a narrower channel, increasing the contact opportunity and contact time between the air and the fin surface, and at the same time enhancing the turbulent flow effect of the air flow. This turbulent state can effectively break the boundary layer of the air on the fin surface, improve the heat exchange efficiency, which is especially suitable for the situation where the cold air has poor fluidity in the heating mode, and helps to accelerate the transfer of heat from the heat exchange tube to the air.

[0079] In one embodiment, S100: Obtain the current inner machine ambient temperature and the current outer machine ambient temperature, including: obtaining the current inner machine ambient temperature through the first temperature sensor set in the preset area of the inner machine fins; obtaining the current outer machine ambient temperature through the second temperature sensor set in the preset area of the outer machine fins.

[0080] In this embodiment, in order to accurately monitor the working environment temperature of the inner and outer machine fins, high-precision and high-sensitivity temperature sensors (thermistors) are used for real-time temperature monitoring. These temperature sensors are deployed in the nearby areas of the inner and outer machine fins to ensure obtaining the most accurate temperature data, providing a reliable basis for subsequent fin shape judgment and parameter adjustment.

[0081] For the inner machine fins, the first temperature sensor is set in the preset area of the inner machine fins. This preset area includes the inlet and outlet of the inner machine heat exchanger and the positions near the inner machine heat exchanger fins. Specifically, installing high-precision temperature sensors on the surface or adjacent areas of the inner machine fins can directly measure the actual temperature environment where the fins are located. These sensors are arranged at typical positions that can represent the temperature distribution of the entire inner machine fins, ensuring that the measurement data can accurately reflect the temperature state of the fins.

[0082] For the outer machine fins, the second temperature sensor is set in the preset area of the outer machine fins. These sensors are installed near the outer machine heat exchanger fins and can monitor the influence of the external environment temperature on the outer machine fins in real time.

[0083] By arranging temperature sensors in the preset areas of the indoor fins and the outdoor fins, this embodiment can obtain the ambient temperatures of the indoor and outdoor units, thereby accurately judging the current morphological state of the fins. This enables the air conditioner's control system to promptly sense the morphological changes that have occurred to the fins and adjust the operating parameters accordingly, allowing the air conditioner to make full use of the improvement in heat exchange efficiency brought about by the morphological changes of the fins and optimize the overall performance. The shape memory alloy fins will automatically deform according to the temperature, and the role of the temperature sensor is to let the control system know that such a change has occurred so as to make corresponding parameter adjustments.

[0084] As Figures 2a - 2e shown, in one embodiment, determining the first current morphology of the indoor fins according to the current indoor ambient temperature includes: when the current indoor ambient temperature is higher than the first indoor temperature threshold and lower than the second indoor temperature threshold, the first current morphology of the indoor fins is the first original morphology; when the current indoor ambient temperature is lower than the first indoor temperature threshold, the first current morphology of the indoor fins is the curled deformation morphology; when the current indoor ambient temperature is higher than the second indoor temperature threshold, the first current morphology of the indoor fins is the micro-rib heightening morphology.

[0085] In this embodiment, the indoor fins are made of a shape memory alloy with a specific phase change temperature and can spontaneously deform according to the ambient temperature. The shape memory alloy has specific phase change temperature characteristics, and each phase change has a starting temperature point (Mf) and a completion temperature point (Af). Specifically:

[0086] For the deformation of the indoor fins in the cooling mode:

[0087] The first indoor temperature threshold mainly corresponds to 18°C (Mf), which is the starting temperature point at which the shape memory alloy begins to change from the flat state to the curled deformation morphology. When the temperature continues to decrease and stabilizes, the fins are completely deformed into the curled morphology. If the temperature rises back to 20°C (Af), the fins will start to gradually recover from the curled deformation morphology to the first original morphology. This Af point (austenite completion temperature) is the temperature point at which the shape memory alloy completes the reverse phase change during the temperature rise process.

[0088] For the deformation of the indoor fins in the heating mode:

[0089] The second indoor temperature threshold mainly corresponds to 28°C (Mf), which is the starting temperature point at which the fins begin to change from the flat state to the micro-rib heightening morphology. When the temperature continues to rise to 30°C (Af), the fins are completely deformed into the micro-rib heightening morphology. If the temperature drops below 28°C, the fins will gradually recover to the first original morphology.

[0090] This bi-directional temperature response characteristic (Mf and Af) is a physical property of the shape memory alloy, enabling the fin to automatically perform bi-directional morphological adjustments according to temperature changes. When the indoor unit ambient temperature is within the normal operating range of 20°C to 28°C, the indoor unit fin maintains the first original form, i.e., a relatively flat basic state.

[0091] This embodiment utilizes the two-way shape memory effect of the shape memory alloy to enable the fin to spontaneously switch between different forms according to temperature without active control. The air-conditioning system only needs to monitor the indoor unit ambient temperature through a temperature sensor to confirm the morphological state of the fin, providing a basis for subsequent operating parameter adjustment. This temperature-based shape change matches the heat exchange and flow characteristics of the air, thereby optimizing the heat exchange performance of the indoor unit in different operating modes without an additional mechanical drive system, greatly improving the reliability and service life of the air conditioner.

[0092] In this embodiment, in the air-conditioning cooling mode, 18°C is selected as the lower temperature point at which the shape of the indoor unit fin starts to change because near this temperature, condensed water begins to form on the surface of the indoor unit fin, affecting the heat exchange efficiency. When the indoor unit temperature drops to this temperature threshold or below, the edges of the indoor unit fin will automatically curl upward. This transformation process is gradual and starts from the edge part of the fin. Due to the influence of temperature on the memory alloy, the alloy begins to contract, causing the edge of the fin to curl slightly upward. As the temperature further decreases, this contraction gradually spreads to the interior of the fin, causing the entire fin to gradually change from a flat state to a curved state. This form makes it easier for the condensed water to flow down in the form of water droplets under the action of gravity, avoiding the formation of a large-area water film, effectively reducing the obstruction of the condensed water film to heat exchange, and improving the cooling efficiency.

[0093] In this embodiment, in the air-conditioning heating mode, 28°C is selected as the starting temperature point for the shape change of the indoor unit fin. When the indoor unit temperature rises to this temperature threshold or above, the fin will gradually become straighter, the spacing decreases, and the height of the micro-ribs increases, transforming into a micro-rib height-increased form. This form is particularly suitable for dealing with cold air during the heating process, capable of effectively constraining the poorly flowing cold air and prompting it to form a turbulent state, enhancing the heat exchange efficiency.

[0094] In this embodiment, in the micro-rib height-increased form, the height of the surface micro-ribs 411 slightly increases, which causes the disturbance of the air on the fin surface to start to enhance. As the temperature continues to rise, the fin gradually becomes straighter, and each part evenly extends along its length direction. At the same time, the fin spacing decreases, and the depth of the groove structure 412 relatively increases, further guiding the flow direction of the air.

[0095] This form is particularly suitable for dealing with relatively cold air. When the relatively cold air enters the heat exchanger, its density is relatively large and its fluidity is relatively poor. The straight and closely spaced fins can effectively restrict the air flow, enabling the air to better form turbulence between the fins, greatly enhancing the heat exchange efficiency between the air and the fins.

[0096] In the above embodiments, the setting of these temperature thresholds enables the shape memory alloy fins to automatically adjust their shapes according to the change of the indoor unit temperature during the refrigeration and heating processes, thereby optimizing the heat exchange performance of the indoor unit and improving the overall energy efficiency of the air conditioner. By performing a heat treatment process on the shape memory alloy material, its phase change can be controlled at these temperature threshold points to achieve the expected shape change effect.

[0097] As Figure 3 shown, in one embodiment, when the current outdoor unit ambient temperature is higher than the first outdoor unit temperature threshold and lower than the second outdoor unit temperature threshold, the second current form of the outdoor unit fins is the second original form; when the current outdoor unit ambient temperature is lower than the first outdoor unit temperature threshold, the second current form of the outdoor unit fins is the contracted deformation form; when the current outdoor unit ambient temperature is higher than the second outdoor unit temperature threshold, the second current form of the outdoor unit fins is the expanded deformation form.

[0098] In this embodiment, the outdoor unit fins are also made of an alloy material with shape memory function and can spontaneously change their shapes according to the outdoor unit ambient temperature. The shape memory alloy of the outdoor unit fins also has specific phase change temperature characteristics, and each phase change has a corresponding temperature range. Specifically:

[0099] For the deformation of the outdoor unit fins in the heating mode:

[0100] The first outdoor unit temperature threshold mainly corresponds to -5°C (Mf), which is the starting temperature point for the outdoor unit fins to start changing from the original form to the contracted deformation form in a cold environment.

[0101] When the ambient temperature of the outdoor unit drops close to -5°C, the shape memory alloy outdoor unit fins start to respond to the temperature change and change their shapes. At first, the overall fins will show a relatively obvious contraction phenomenon, making the surface area of the fins relatively decrease. This contraction helps the fins better "dock" with the low-temperature air for heat exchange and absorb heat from the low-temperature air more efficiently.

[0102] As the temperature continues to drop, the fins will continue to make dynamic adjustments according to the temperature change to further optimize their shapes to adapt to the lower temperature environment and ensure continuous and stable heat absorption from the low-temperature air.

[0103] When the temperature rises close to 0°C (Af), the fins will make appropriate restorative adjustments according to the temperature at this time to maintain stable heat absorption performance during subsequent temperature changes.

[0104] For deformation of external unit fins in cooling mode:

[0105] The second external unit temperature threshold mainly corresponds to 43°C (Mf), which is the starting temperature point at which the external unit fin begins to transform from the original form to the extended deformation form in a high temperature environment.

[0106] When the air temperature around the outdoor unit gradually rises and approaches 43°C, the shape memory alloy outdoor unit fins begin to change shape. Initially, the edge or local area of ​​the fins first sense the temperature change, causing these parts to first show slight deformation, such as slight warping or local twisting.

[0107] As the temperature rises further, this deformation gradually spreads from the local area to the entire fin. The fin as a whole changes from the original relatively flat plane state to a three-dimensional expansion form, and various complex deformation forms such as bending and twisting appear, making the spatial structure of the fin more three-dimensional. From a thermodynamic point of view, when the fin is deformed into a three-dimensional expansion or twisted state, it breaks the relatively stable air boundary layer originally formed on the surface of the fin. Before deformation, the air flows on the surface of the fin in a laminar state, and the heat exchange mainly relies on the slow conduction of air molecules, which is relatively inefficient. The turbulence formed after deformation makes the movement of air molecules more disordered and violent, greatly increasing the contact area and frequency between the air and the fin, and can transfer heat from the fin to the air more quickly and fully, thereby significantly improving the heat dissipation efficiency of the outdoor unit.

[0108] When the temperature rises to 45°C (Af), the fins are completely deformed into an extended form, which can break the air boundary layer to the maximum extent and enhance the heat dissipation effect.

[0109] When the ambient temperature of the external unit is within the normal operating range of 0°C to 43°C, the external unit fins maintain the second original form, that is, a relatively flat basic state, and can meet normal heat dissipation or heat absorption requirements without special deformation.

[0110] Through this temperature-based adaptive deformation mechanism, the external fins can automatically adjust their shape to different extreme working environments:

[0111] In high temperature environments (cooling mode), the expanded and deformed fins can break the relatively stable air boundary layer originally formed on the fin surface from a thermodynamic perspective, promote the formation of air turbulence, and significantly improve the heat dissipation efficiency. This solves the problem of the reduced heat dissipation efficiency of traditional external unit fins in high temperature environments.

[0112] In a low-temperature environment (heating mode), the fins in the contracted and deformed state can come into closer contact with the low-temperature air, increasing the effective contact area. At the same time, the flow state of the air around the fins is changed, enabling the low-temperature air to transfer heat to the fins more smoothly, thus improving the efficiency of the outdoor unit in absorbing heat from the low-temperature air.

[0113] In this embodiment, by utilizing the temperature-responsive characteristics of the shape memory alloy, the fins of the outdoor unit can automatically adjust to the most suitable form for the current working conditions according to the ambient temperature, without any additional mechanical drive or control device. Only by monitoring the ambient temperature of the outdoor unit through a temperature sensor can the current form state of the fins be confirmed, providing a basis for subsequent adjustment of operating parameters. This design improves the working efficiency of the air conditioner outdoor unit in extreme temperature environments.

[0114] In one embodiment, adjusting the operating parameters of the air conditioner according to the first current form and the second current form includes: obtaining the operating mode selected by the user, where the operating mode includes an energy-saving mode and a performance mode; when the user selects the energy-saving mode: if the first current form of the indoor unit fins is a curled and deformed state or a micro-rib heightening state, reduce the compressor frequency and / or the indoor unit fan speed; if the second current form of the outdoor unit fins is a contracted and deformed state or an extended and deformed state, reduce the compressor frequency and / or the outdoor unit fan speed; when the user selects the performance mode: if the first current form of the indoor unit fins is a curled and deformed state or a micro-rib heightening state, maintain or increase the compressor frequency and / or the indoor unit fan speed; if the second current form of the outdoor unit fins is a contracted and deformed state or an extended and deformed state, maintain or increase the compressor frequency and / or the outdoor unit fan speed.

[0115] In this embodiment, first, the basic control strategy is determined according to the operating mode (energy-saving mode or performance mode) selected by the user, and then adjustments are made in combination with the current form of the fins. The detailed control process is as follows:

[0116] Obtain the operating mode selected by the user:

[0117] The control system of the air conditioner obtains the mode selection of the user through the user interface (such as a remote control or a mobile phone APP), including two options: an energy-saving mode and a performance mode. The energy-saving mode aims to reduce energy consumption, while the performance mode focuses on providing the best cooling or heating effect.

[0118] When the user selects the energy-saving mode:

[0119] If it is detected that the indoor unit fins are in a curled and deformed state (temperature below 18°C) or a micro-rib heightening state (temperature above 28°C), reduce the compressor frequency and / or the indoor unit fan speed. The specific adjustment method is: reduce the compressor frequency to 80%-90% of the original frequency, and avoid specific shielding points during the reduction process to reduce noise; reduce the indoor unit fan speed to 80% of the original speed.

[0120] If it is detected that the outdoor unit fins are in a contracted and deformed state (temperature lower than -5°C) or an expanded and deformed state (temperature higher than 43°C), reduce the compressor frequency and / or the rotational speed of the outdoor unit fan. The specific adjustment method is as follows: the compressor frequency is reduced in the same way; the rotational speed of the outdoor unit fan is reduced to 80% of the original rotational speed.

[0121] In the energy-saving mode, by utilizing the improvement in heat exchange efficiency brought about by the change in the fin shape, reduce energy consumption by reducing the motor power and the compressor frequency, while maintaining a performance equivalent to the original cooling or heating effect.

[0122] When the user selects the performance mode:

[0123] If it is detected that the indoor unit fins are in a curled and deformed state or a micro-rib heightening state, maintain or appropriately increase the compressor frequency and / or the rotational speed of the indoor unit fan to make full use of the improvement in heat exchange efficiency brought about by the change in the fin shape and further enhance the cooling or heating effect.

[0124] If it is detected that the outdoor unit fins are in a contracted and deformed state or an expanded and deformed state, maintain or appropriately increase the compressor frequency and / or the rotational speed of the outdoor unit fan so that the outdoor unit can achieve the best performance under extreme temperature conditions.

[0125] In the performance mode, the air conditioner control system does not reduce any operating parameters, but makes full use of the improvement in heat exchange efficiency brought about by the change in the fin shape, combined with the maintained or increased power input, to provide the user with a stronger cooling or heating effect, which is especially suitable for scenarios where rapid cooling or heating is required.

[0126] Through this dual-mode design, the air conditioner system can operate flexibly according to the actual needs of the user, meeting the needs of users who pursue energy conservation and environmental protection as well as the needs of users who pursue rapid temperature control effects.

[0127] In one embodiment, after adjusting the operating parameters of the air conditioner according to the first current shape and the second current shape, the method further includes: continuously monitoring the heat exchange efficiency of the air conditioner; when the heat exchange efficiency is lower than the preset efficiency threshold, perform the following operations: if the first current shape of the indoor unit fins is a curled and deformed state or a micro-rib heightening state, increase the rotational speed of the indoor unit fan; if the second current shape of the outdoor unit fins is a contracted and deformed state or an expanded and deformed state, increase the rotational speed of the outdoor unit fan; continuously adjust the rotational speed of the indoor unit fan and / or the outdoor unit fan until the heat exchange efficiency reaches or exceeds the preset efficiency threshold.

[0128] In this embodiment, data is collected by a temperature sensor to calculate the actual heat exchange efficiency of the air conditioner. The calculation method of the heat exchange efficiency can be to monitor indicators such as the change rate of the indoor temperature or the temperature difference change between the indoor and outdoor heat exchangers. For example, in the cooling mode, the current heat exchange efficiency can be evaluated by calculating the rate of decrease in the indoor temperature per unit time; in the heating mode, it can be evaluated by calculating the rate of increase in the indoor temperature per unit time.

[0129] Compare the calculated current heat exchange efficiency with a preset efficiency threshold. The preset efficiency threshold represents the performance standard that the air conditioner should achieve under normal operating conditions.

[0130] When it is detected that the current heat exchange efficiency is lower than the preset efficiency threshold, corresponding operations will be performed according to the current form of the fins:

[0131] For the indoor unit fins:

[0132] When the indoor unit fins are in a curled deformation form or a micro-rib heightening form, increase the rotational speed of the indoor unit fan. This is because although these forms themselves help to improve the heat exchange efficiency, under certain extreme conditions (such as sudden changes in outdoor temperature, abnormal indoor humidity, etc.), it may be necessary to increase the air volume to further enhance the heat exchange process.

[0133] Increasing the rotational speed of the indoor unit fan can increase the air flow rate, enhance the contact between the air and the fins, strengthen the heat exchange, and thus improve the overall heat exchange efficiency.

[0134] For the outdoor unit fins:

[0135] When the outdoor unit fins are in a contracted deformation form or an extended deformation form, increase the rotational speed of the outdoor unit fan. This is because in an extreme temperature environment, although the shape memory alloy fins have deformed to adapt to the current environment, it may still be necessary to increase the air volume to ensure sufficient heat exchange.

[0136] In a low-temperature environment (the fins are in a contracted deformation form), increasing the rotational speed of the outdoor unit fan can strengthen the contact between the low-temperature air and the fins and improve the heat absorption efficiency.

[0137] In a high-temperature environment (the fins are in an extended deformation form), increasing the rotational speed of the outdoor unit fan can strengthen the air flow disturbance, better break the air boundary layer, and improve the heat dissipation efficiency.

[0138] In this embodiment, continuously adjust the rotational speed of the indoor unit fan and / or the outdoor unit fan, and continuously monitor the change in the heat exchange efficiency. This adjustment is not a one-time operation, but a gradual process. Gradually increase the rotational speed of the fan according to the real-time change of the efficiency until the heat exchange efficiency reaches or exceeds the preset efficiency threshold.

[0139] Such as Figures 2a - 2eAs shown, in one embodiment, the surface of the indoor unit fin is provided with micro-ribs 411 and groove structures 412.

[0140] In this embodiment, a plurality of tiny protrusion structures are provided on the surface of the indoor unit fin as micro-ribs 411. When the shape of the indoor unit fin changes according to the temperature, the position and angle of the micro-rib 411 structure will also be adjusted accordingly. At this time, the air flow boundary layer on the fin surface can be broken, promoting the formation of turbulent flow and improving the heat exchange efficiency.

[0141] On the other surface of the indoor unit fin, the groove structure 412 arranged opposite to the micro-rib 411 can enable the air to form an orderly flow path on the fin surface. Moreover, in the cooling mode, it helps to collect and guide the condensed water, reducing the formation of the water film. In addition, it increases the residence time of the air on the fin surface and improves the heat exchange efficiency.

[0142] As Figure 4 shown, corresponding to the air conditioner control method of the above embodiment, this embodiment also provides an air conditioner control device, which is deployed in the air conditioner system.

[0143] The air conditioner control device provided in this embodiment includes a temperature acquisition unit, a shape determination unit, and a parameter adjustment unit. The air conditioner control device is deployed in the air conditioner, and the air conditioner includes an indoor unit fin with a shape memory function and an outdoor unit fin with a shape memory function. The indoor unit fin can be in a first original shape, a curled deformation shape, or a micro-rib heightening shape according to the current indoor unit environment temperature, and the outdoor unit fin can be in a second original shape, a contracted deformation shape, or an extended deformation shape according to the current outdoor unit environment temperature. The air conditioner control device includes:

[0144] A temperature acquisition unit for acquiring the current indoor unit environment temperature and the current outdoor unit environment temperature. Specifically, the temperature acquisition unit includes temperature sensors arranged near the indoor unit and the outdoor unit, and these temperature sensors can collect the ambient temperatures near the indoor unit fin and the outdoor unit fin in real time.

[0145] A shape determination unit for determining the first current shape of the indoor unit fin according to the current indoor unit environment temperature and the second current shape of the outdoor unit fin according to the current outdoor unit environment temperature. This unit receives the temperature data from the temperature acquisition unit to judge the current shape state of the indoor and outdoor unit fins.

[0146] The working principle of the shape determination unit is based on comparing the preset temperature threshold with the real-time temperature data. For the indoor unit fin, when it is detected that the current indoor unit environment temperature is lower than 18°C (Mf), it is recognized that the indoor unit fin is in a curled deformation shape; when it is detected that the temperature is higher than 28°C (Mf), it is recognized that the indoor unit fin is in a micro-rib heightening shape; when the temperature is between 20°C (Af) and 28°C, it is recognized that the indoor unit fin is in the first original shape.

[0147] Similarly, for the outdoor unit fins, when it is detected that the current outdoor unit ambient temperature is lower than -5°C (Mf), it is recognized that the outdoor unit fins are in a contracted and deformed state; when it is detected that the temperature is higher than 43°C (Mf), it is recognized that the outdoor unit fins are in an extended and deformed state; when the temperature is between 0°C (Af) and 43°C, it is recognized that the outdoor unit fins are in the second original state.

[0148] It should be noted that the form determination unit does not control the form change of the fins because the shape memory alloy fins deform spontaneously according to the temperature. The role of this unit is to identify the current form of the fins and provide a basis for the next parameter adjustment.

[0149] The parameter adjustment unit is used to adjust the operating parameters of the air conditioner according to the first current form and the second current form. This unit adjusts the operating parameters of the air conditioning system according to the current fin form obtained by the form determination unit, combined with the operating mode of the air conditioner (energy-saving mode or performance mode), so as to maximize the heat exchange efficiency improvement brought by the deformation of the shape memory alloy fins.

[0150] Specifically, the operating parameters that the parameter adjustment unit can adjust include: compressor frequency, indoor fan speed, outdoor fan speed, etc. When it is detected that the indoor unit fins are in a curled and deformed state or a micro-rib heightening state, or the outdoor unit fins are in a contracted and deformed state or an extended and deformed state, it indicates that the fins have automatically adjusted their shapes according to the ambient temperature to improve the heat exchange efficiency. At this time, the parameter adjustment unit will make corresponding adjustments according to the selected operating mode by the user:

[0151] In the energy-saving mode: when the form of the indoor unit fins changes, the parameter adjustment unit will reduce the compressor frequency and / or the indoor fan speed, using the heat exchange efficiency improvement brought by the fin form change to offset the impact of power reduction, maintaining the original cooling / heating effect while reducing energy consumption. When the form of the outdoor unit fins changes, the parameter adjustment unit will reduce the compressor frequency and / or the outdoor fan speed, also using the heat exchange efficiency improvement to ensure performance and reduce energy consumption.

[0152] In the performance mode: when the fin form changes, the parameter adjustment unit will maintain or appropriately increase the compressor frequency and the fan speed to further improve the cooling / heating performance of the air conditioner and provide a more comfortable environmental experience for the user.

[0153] The air conditioner control device provided in this embodiment realizes the control of the dual-temperature response shape memory alloy fin air conditioning system through the coordinated work of the temperature acquisition unit, the form determination unit, and the parameter adjustment unit. This device can accurately obtain the current form of the fins and optimize the operating parameters of the air conditioner accordingly, giving full play to the temperature self-adaptive advantage of the shape memory alloy fins. It can not only reduce energy consumption while maintaining the cooling and heating effects, but also improve the performance of the air conditioner under the same energy consumption, providing a more energy-efficient and high-performance air conditioner usage experience for users.
