[0002] With the continuous improvement of people's living standards, air conditioners have become an indispensable electrical appliance in daily life. While existing air conditioner control methods can basically meet the indoor temperature requirements in heating mode, some problems still need to be solved in actual use. The control of air conditioners in related technologies is not precise enough. After heating is turned on, the air deflector is angled upwards to avoid direct airflow, and the deflector guides heat upwards, resulting in slower heat output during the heating phase. This leads to a delayed decrease in the user's perception of heat delivery, reducing the user experience. Summary of the Invention

Detailed Implementation

[0027] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0028] Traditional air conditioners rely on simple adjustments of fan speed and direction to prevent cold air from blowing directly on people, offering a relatively limited functionality. As people's demands for quality of life increase, the comfort features of air conditioners are receiving more attention. Some high-end air conditioning systems can achieve independent temperature control in specific areas, adjusting airflow and temperature according to the needs of different zones. Traditional systems enter an anti-cold-wind mode upon heating, with the air deflector angled upwards to avoid direct airflow. This deflector guides heat upwards, leading users lacking knowledge of anti-cold-wind protection to mistakenly believe that heat delivery is delayed, resulting in misleading advertising. Therefore, users who want to exit the anti-cold-wind mode as soon as possible or feel warm air immediately upon heating activation require improved research and development of anti-cold-wind control methods.

[0029] The following description, with reference to the accompanying drawings, describes an air conditioning control method, apparatus, electronic device, chip, and storage medium according to embodiments of this application.

[0030] Figure 1 This is a schematic diagram of an air conditioning control process provided in an embodiment of this application.

[0031] As one implementation, the air conditioning control method of this application embodiment can be configured in an air conditioning control device, which can be applied to any electronic device so that the electronic device can perform air conditioning control functions.

[0032] Among them, electronic devices can be any device with computing capabilities, such as mobile terminals, which can be hardware devices with various operating systems, touch screens and / or displays, such as mobile phones, tablets, personal digital assistants, wearable devices, etc.

[0033] As another implementation, the air conditioning control method of this application embodiment can also be executed by a chip with processing capabilities. The chip includes an image signal processing chip (ISP), a central processing unit (CPU), an application-specific integrated circuit (ASIC), a digital signal processor (DSP), a field-programmable gate array (FPGA), a system on a chip (SOC), a reduced instruction set computer (RISC), etc., which will not be listed here.

[0034] It should be noted that all data collection operations related to users in this application are conducted with the user's authorization and in strict compliance with relevant laws and regulations such as privacy and security.

[0035] like Figure 1 As shown, the method may include the following steps: Step 101: In response to the heating operation command for the air conditioner, adjust the speed of the indoor fan of the air conditioner according to the target anti-cold air state range in which the temperature of the indoor pipe of the air conditioner is located; wherein, the target anti-cold air state range is used to determine the corresponding indoor fan control strategy.

[0036] In this embodiment, when a user sends a heating operation command to the air conditioner, it can be determined that the user intends to turn on the air conditioner for heating. Then, based on the important parameter of the air conditioner's internal pipe temperature, the speed of the air conditioner's internal fan is dynamically adjusted within the set target anti-cold air state range to prevent cold air from being blown out and improve the user's comfort.

[0037] The purpose of the anti-cold air mode is to optimize the anti-cold air effect during the initial heating phase by controlling the air conditioner's operating parameters in stages. After the air conditioner starts heating mode, the anti-cold air operation process is divided into different zones based on changes in the internal pipe temperature. Each zone corresponds to a specific internal fan control strategy. This zoned control method allows the air conditioner to more precisely adjust its operating status at different stages.

[0038] The target anti-cold air state range is determined based on the internal pipe temperature of the air conditioner, and the internal fan control strategy corresponding to the target anti-cold air state range is scheduled to control the operation of the air conditioner's internal fan.

[0039] Optionally, adjusting the speed of the indoor fan of the air conditioner according to the target anti-cold air state range where the indoor pipe temperature of the air conditioner is located includes: The target anti-cold air state range is determined based on the temperature range of the internal pipe temperature of the air conditioner. Within the target anti-cold air state range, the speed of the air conditioner's indoor fan is adjusted according to the corresponding indoor fan control strategy.

[0040] This embodiment further clarifies the specific operational procedure for determining the target anti-cold air state range based on the internal pipe temperature of the air conditioner, and adjusting the internal fan speed accordingly. The target anti-cold air state range is determined by real-time monitoring of the internal pipe temperature of the air conditioner and based on its temperature range.

[0041] Different temperature ranges correspond to different cold air prevention needs and operating strategies. Once the target cold air prevention range is determined, the speed of the air conditioner's indoor fan can be finely adjusted within that range. Based on the temperature change trend and heating demand within the range, the indoor fan speed is dynamically changed to ensure that heating efficiency and energy utilization are maximized while preventing cold air.

[0042] Optionally, adjusting the speed of the air conditioner's indoor fan according to the corresponding indoor fan control strategy within the target anti-cold air state range includes: The upper limit of the internal fan speed of the air conditioner is controlled according to the target anti-cold air state range.

[0043] In this embodiment, precise cold air prevention is achieved by controlling the upper limit of the indoor fan speed. Specifically, within the target cold air prevention range, an upper limit value for the indoor fan speed is set based on the characteristics of that range. During actual operation, the indoor fan speed will be controlled below this upper limit value. This effectively prevents cold air from being blown out of the air outlet due to excessive indoor fan speed, while ensuring that the air conditioner has sufficient airflow to deliver hot air, achieving a comfortable heating effect. In this way, fine-grained control of the indoor fan speed is achieved, improving the operational stability and comfort of the air conditioner in heating mode.

[0044] Optionally, controlling the upper limit of the air conditioner's internal fan speed according to the target anti-cold air state range includes: Determine the wind speed level corresponding to the target cold wind protection state range; The speed of the air conditioner's internal fan is controlled according to the upper speed limit corresponding to the fan speed setting, so that the speed of the air conditioner's internal fan is lower than the upper speed limit in the target anti-cold air state range.

[0045] In this embodiment, the fan speed setting corresponding to the target cold air prevention state range is determined. There is a one-to-one correspondence between this fan speed setting and the target cold air prevention state range. Different fan speed settings represent different airflow and speed ranges, suitable for different indoor environments and user needs. After determining the corresponding fan speed setting, the speed of the air conditioner's indoor fan can be controlled according to the upper speed limit specified by that setting. Specifically, through corresponding control algorithms and motor speed regulation technology, it is ensured that the actual speed of the indoor fan is always lower than the set upper speed limit. This effectively prevents cold air from being blown out and ensures that the air conditioner operates with appropriate fan speed and airflow for heating within the target cold air prevention state range, improving the user experience and the air conditioner's heating performance.

[0046] In one possible embodiment, the correspondence between the anti-cold air state range, temperature range, and wind speed is shown in Table 1:

[0047] Table 1 During the heating process, the temperature of the air conditioner's internal pipes continuously rises. Based on the temperature range of the internal pipes, the target anti-cold air condition range is determined, and the speed of the internal fan is further determined. In the anti-cold air condition range where the internal pipe temperature is low, the speed of the air conditioner's internal fan is limited to a low level to avoid a large amount of cold air; while when the internal pipe temperature rises, the fan speed can be increased to ensure the comfort of the air conditioner's airflow.

[0048] TEL0-TEL6 are the boundary values ​​of the temperature range. If the internal pipe temperature T... 内管 Satisfying TEL1≤T 内管 If the temperature range is <TEL2, which is within the range of [TEL1, TEL2], then the anti-cold air condition range 1 can be determined as the target anti-cold air condition range. Furthermore, each anti-cold air condition range has a corresponding upper speed limit, used to restrict the speed of the air conditioner's internal fan within the corresponding temperature range; the higher the temperature, the higher the upper speed limit of the internal fan.

[0049] Optionally, adjusting the speed of the air conditioner's indoor fan according to the corresponding indoor fan control strategy within the target anti-cold air state range includes: The internal fan speed is adjusted based on the change in the internal pipe temperature and the internal pipe temperature difference threshold corresponding to the target anti-cold air state range.

[0050] In this embodiment, in addition to determining the target anti-cold air state range and adjusting the fan speed based on the temperature range of the inner pipe, a dynamic parameter—the change in inner pipe temperature—is introduced as the adjustment basis. Specifically, within the target anti-cold air state range, the change in inner pipe temperature, i.e., the increase in inner pipe temperature, is periodically monitored and compared with the corresponding inner pipe temperature difference threshold. If the change in inner pipe temperature is lower than the inner pipe temperature difference threshold, it indicates that the current heating effect may not be ideal. In this case, the fan speed needs to be adjusted accordingly to accelerate heat transfer and the rate of increase in indoor temperature, thereby improving heating efficiency and user comfort. This dynamic adjustment strategy based on the rate of temperature increase allows the air conditioner to more intelligently adapt to different operating conditions, further optimizing the heating effect.

[0051] Optionally, adjusting the internal fan speed based on the change in the internal pipe temperature and the internal pipe temperature difference threshold corresponding to the target anti-cold air state range includes: In response to the change in the inner pipe temperature being lower than the inner pipe temperature difference threshold corresponding to the target anti-cold air state range, while reducing the inner pipe temperature according to a preset temperature compensation value, the air conditioner's internal fan speed is simultaneously reduced according to a preset speed compensation value.

[0052] In this embodiment, when the change in the inner pipe temperature is lower than the inner pipe temperature difference threshold corresponding to the target anti-cold air state range, the inner pipe temperature is reduced according to the preset temperature compensation value. Since the target anti-cold air state range of the air conditioner is determined based on the inner pipe temperature, the purpose of this operation is to make the air conditioner run at a low fan speed for a longer time in the current target anti-cold air state range, thereby reducing the user discomfort caused by the low inner pipe temperature.

[0053] At the same time, the speed of the air conditioner's internal fan will be reduced synchronously according to a preset speed compensation value. This slows down the rate at which cold air is blown out, allowing more time for heat to accumulate and exchange inside the air conditioner, thus accelerating the actual rate of temperature rise in the internal pipes and enabling the air conditioner to reach a stable heating state more quickly. This coordinated compensation adjustment mechanism effectively solves the problem of slow temperature rise, improving the air conditioner's heating performance and user satisfaction.

[0054] Figure 2 This is a schematic diagram of a speed and pipe temperature threshold compensation rule proposed in an embodiment of this application, as shown below. Figure 2 As shown, in one possible embodiment, in order to increase the rate of temperature rise of the inner tube, reduce the anti-cold air operation time, and improve the anti-cold air effect, the temperature difference of the inner tube rise is judged. When the corresponding inner tube temperature difference is ≤ the set temperature difference threshold, the operating speed of the inner fan is compensated, with a speed compensation Δ = -30 rpm; and the upper limit of the temperature of the current anti-cold air zone is compensated, with a compensation value ΔTm = 2℃.

[0055] When in anti-cold air zones 1-5, a timer is activated (reset upon entering an anti-cold air zone). The inner pipe temperature is checked every 10 seconds. In anti-cold air zone 1, the temperature difference rising in the inner pipe is set to ΔT1, with a first temperature difference threshold of 1.5℃. When ΔT1 ≤ 1.5℃, the internal fan speed decreases by 30 rpm, and compensation is applied to the starting pipe temperature threshold TEL2 of fan baffle 2, with a compensation value ΔTm = 2℃. In anti-cold air zone 2, the temperature difference rising in the inner pipe is set to ΔT2, with a first temperature difference threshold of 1.2℃. When ΔT2 ≤ 1.2℃, the internal fan speed decreases by 30 rpm, and compensation is applied to the starting pipe temperature threshold TEL3 of fan baffle 3, with a compensation value ΔTm = 2℃. In anti-cold air zone 3, the temperature difference rising in the inner pipe is set to ΔT3. The first temperature difference threshold is 0.9℃. When ΔT3≤0.9℃, the internal fan speed is reduced by 30rpm, and the starting pipe temperature threshold TEL4 of the fan baffle 4 is compensated, with a compensation value ΔTm=2℃. When in the anti-cold air zone 4, the internal pipe temperature difference is set to ΔT4, and the first temperature difference threshold is 0.6℃. When ΔT4≤0.6℃, the internal fan speed is reduced by 30rpm, and the starting pipe temperature threshold TEL5 of the fan baffle 5 is compensated, with a compensation value ΔTm=2℃. When in the anti-cold air zone 5, the internal pipe temperature difference is set to ΔT5, and the first temperature difference threshold is 0.3℃. When ΔT5≤0.6℃, the internal fan speed is reduced by 30rpm, and the starting pipe temperature threshold TEL6 of the set speed Rs is compensated, with a compensation value ΔTm=2℃. It should be noted that compensating for the starting pipe temperature threshold of each fan speed by increasing the starting pipe temperature threshold, and compensating for the inner pipe temperature by decreasing the inner pipe temperature mentioned above, have the same effect: to extend the time the air conditioner operates in the current anti-cold air zone, allowing more time for heat to accumulate inside the air conditioner and increasing the rate of temperature rise.

[0056] Optionally, the method further includes: The operation of the compressor is controlled according to the rate of increase of the inner pipe temperature or the rate of increase of the exhaust temperature of the air conditioner compressor, so as to regulate the heating rate of the compressor.

[0057] In this embodiment, in order to further improve the heating performance of the air conditioner, enhance the anti-cold air effect, and reduce the risk of users being directly exposed to cold air, the operating status of the compressor is controlled by combining the two factors of the inner pipe rising rate or the exhaust temperature rising rate, thereby achieving precise regulation of the compressor heating rate. According to the division of the anti-cold air state range, the compressor frequency rising rate is adjusted to meet the heating capacity requirements of different ranges.

[0058] Optionally, controlling the operation of the compressor based on the rate of increase of the inner pipe temperature or the rate of increase of the exhaust temperature of the air conditioning compressor includes at least one of the following: In response to the inner tube temperature rising rate being lower than the corresponding inner tube temperature rising rate threshold, the compressor frequency is adjusted according to a preset frequency compensation value to improve the compressor's heating rate. In response to the exhaust temperature rise rate being lower than the corresponding exhaust temperature rise rate threshold, the opening of the electronic expansion valve is adjusted according to a preset opening compensation value to improve the compressor's heating rate.

[0059] In this embodiment, the exhaust temperature of the air conditioner refers to the temperature at which the air conditioner compressor discharges refrigerant gas. It is an important indicator for measuring the operating status and performance of the air conditioner. In heating mode, the exhaust temperature reflects the heating efficiency of the compressor. The faster the exhaust temperature rises, the higher the thermal efficiency of the compressor; the slower the exhaust temperature rises, the lower the thermal efficiency of the compressor.

[0060] When the rate of increase of the inner pipe temperature is lower than the corresponding threshold for the rate of increase of the inner pipe temperature, or when the rate of increase of the exhaust temperature is lower than the corresponding third threshold for the rate of increase, it indicates that the heating system of the air conditioner is not heating enough and has failed to meet expectations. The temperature of the air blown out by the air conditioner will not reach the expected temperature, which will lead to a poor user experience. At this time, the system will control the compressor to increase the heating rate.

[0061] When the rate of temperature rise in the inner pipe is lower than the corresponding threshold, it indicates that the current heating process has failed to reach the expected temperature increase rate. To effectively improve the heating rate of the compressor, the system will adjust the compressor frequency according to a preset frequency compensation value. When the compressor frequency increases, the refrigerant circulation speed in the system accelerates, and the heat transferred per unit time increases, thereby effectively increasing the rate of temperature rise in the inner pipe, enabling the air conditioner to reach the set heating target temperature more quickly.

[0062] When the rate of increase in exhaust temperature is lower than the corresponding threshold, it indicates that the compressor's exhaust temperature change during air conditioning heating is not ideal, which may affect the efficiency of the entire heating system. The system will adjust the opening of the electronic expansion valve according to a preset compensation value to improve the compressor's heating rate. When the rate of increase in exhaust temperature is low, the opening of the electronic expansion valve is appropriately reduced, the orifice diameter decreases, and the overall refrigerant circulation flow rate decreases. This increases the subcooling of the indoor condenser and raises the condensing temperature; simultaneously, the outdoor evaporator's evaporation pressure and temperature decrease; and the high-low pressure difference of the compressor increases, leading to an increase in exhaust temperature.

[0063] This method allows air conditioners to improve heating efficiency and quickly raise indoor temperatures when heating performance falls short of expectations, meeting users' needs for rapid heating. This multi-parameter control strategy ensures that the air conditioner operates at its optimal performance during different operating phases, improving overall heating efficiency and energy utilization.

[0064] Optionally, the method further includes at least one of the following: Based on the target anti-cold air state range, determine the threshold for the rate of temperature rise of the inner tube; The exhaust temperature rise rate threshold is determined based on the target cold air protection state range.

[0065] In this embodiment, the threshold values ​​for the rate of increase of the inner pipe temperature and the rate of increase of the exhaust temperature are determined based on the target cold draft prevention state range. This allows these control thresholds to be dynamically adjusted according to the operating characteristics and heating demands of the air conditioner in different cold draft prevention state ranges, thereby achieving more precise compressor operation control. This threshold determination method based on the target cold draft prevention state range ensures that the air conditioner is controlled with optimal parameters at each operating stage, further optimizing heating performance and operational stability, and improving the user experience.

[0066] In one possible embodiment, the frequency rise rate and the initial opening of the expansion valve are corrected according to Table 2:

[0067] Table 2 To further improve the internal pipe rise rate, enhance the anti-cold air effect, and reduce the risk of users being directly exposed to cold air, the frequency rise rate (increase value) and the expansion valve opening compensation value are adjusted during the start-up phase by combining the internal pipe rise rate and the exhaust temperature rise rate. By increasing the frequency rise rate and decreasing the expansion valve opening, the overall heating capacity of the unit is improved during the initial start-up phase, while simultaneously increasing the air conditioner's outlet temperature. After the internal fan starts, when the speed is within the anti-cold air range 1-5, a timer is activated (the timer is reset after entering the anti-cold air range). Every 20 seconds, the internal pipe temperature rise rate ΔTn and the exhaust temperature rise rate ΔTp are detected. Note that when the frequency reaches the target frequency, frequency and opening corrections are not performed.

[0068] Optionally, following the response to the heating operation command for the air conditioner, the method further includes: The initial speed is determined based on the temperature range of the indoor ambient temperature of the air conditioner; In response to the inner pipe temperature reaching the preset start-up temperature, the air conditioner's indoor fan is started, and the air conditioner's indoor fan is controlled to run at the initial speed.

[0069] In this embodiment, after responding to the heating operation command, a suitable initial speed is first determined based on the temperature range of the indoor environment where the air conditioner is located. This initial speed is determined by comprehensively considering factors such as the human body's sensitivity to cold air in different temperature ranges and the heating demand of the air conditioner. The aim is to ensure that the air conditioner can effectively prevent cold air from blowing out at the beginning of startup and start heating as soon as possible, thereby improving user comfort.

[0070] Then, the air conditioner's indoor fan will only start when the inner pipe temperature reaches the preset start-up temperature, and will be controlled to run at the previously determined initial speed. This design can prevent the indoor fan from starting too early when the inner pipe temperature is too low, causing cold air to be blown out. At the same time, it can also ensure that the air conditioner starts to deliver air and heat in time after the inner pipe temperature reaches a certain level, optimizing the start-up process and operating effect of the air conditioner, and further improving the user experience and heating performance of the air conditioner.

[0071] The initial speed setting conditions for heating operation are shown in Table 3:

[0072] Table 3 Because the rate of temperature rise in the inner pipe is affected by the inner and outer ambient temperatures, the indoor fan speed needs to be compensated and corrected according to changes in the ambient temperature. After the air conditioner is turned on, it is determined whether the air conditioner is in the anti-cold air stage. After entering the anti-cold air mode, the compressor is turned on, and the initial indoor ambient temperature TC-N is detected. The initial starting speed Rmin of the indoor fan is adjusted according to the inner ambient temperature. Generally, as the compressor starts, the lower the initial starting speed of the indoor fan, the less heat dissipation from the coil, and the higher the rate of temperature rise in the inner pipe. Therefore, the initial starting speed Rmin1 for heating operation is less than Rmin2, Rmin2 is less than Rmin3, and Rmin3 is less than Rmin4.

[0073] Optionally, the method further includes: The air sweeping blades are controlled to rotate so that there is an angle between the air sweeping blades and the air outlet direction, and the air sweeping blades are provided with air outlet holes.

[0074] In this embodiment, when a user issues a heating operation command to the air conditioner, the system first controls the air conditioner's sweeping blades to rotate accordingly, creating a specific angle between the sweeping blades and the airflow direction. These sweeping blades are not ordinary blade structures; they are specially designed with air outlets. This reduces the airflow volume during the initial heating phase, resulting in a light breeze. This further reduces the amount of cold air blown out during the initial heating phase, improving comfort. Combined with indoor fan speed control, compressor frequency control, and electronic expansion valve opening control, the system rapidly increases the internal pipe temperature, thereby enhancing the anti-cold air effect.

[0075] In one possible embodiment, the angle between the sweeping blades and the air outlet direction is a right angle, meaning that the sweeping blades completely block the air outlet of the air conditioner, and air can only be discharged from the outlet hole.

[0076] Optionally, the method further includes: In response to the inner tube temperature reaching the preset upper limit of the anti-cold air temperature, the anti-cold air state is exited, and the speed of the air conditioner's internal fan is adjusted according to the fan speed setting in the heating operation command, and the air sweeping blades are controlled to rotate to reduce the angle between the air sweeping blades and the air outlet direction.

[0077] In this embodiment, when the inner pipe temperature reaches the preset upper limit of the anti-cold air temperature, it indicates that the heat inside the air conditioner has accumulated to a certain extent. At this time, the speed of the air conditioner's internal fan will be adjusted accordingly based on the fan speed setting set by the user in the heating operation command, to ensure that the air conditioner can deliver hot air to the room with appropriate airflow and speed. Simultaneously, the rotation of the sweeping blades will be controlled to reduce the angle between the sweeping blades and the airflow direction. The purpose of this operation is to optimize the airflow direction and airflow distribution of the air conditioner by adjusting the angle of the sweeping blades, so that the hot air is delivered more concentratedly to specific areas of the room, thereby accelerating the rise in indoor temperature, improving heating efficiency, and enhancing user comfort.

[0078] Optionally, the method further includes: Determine the corresponding anti-cold air state range based on the fan speed setting in the heating operation command; The upper limit of the anti-cold air temperature is determined based on the upper limit of the temperature range corresponding to the anti-cold air state range.

[0079] In this embodiment, the anti-cold air state range is determined based on the fan speed setting in the heating operation command. Different fan speed settings correspond to different anti-cold air requirements and operating strategies; therefore, it is necessary to accurately determine the corresponding anti-cold air state range based on the fan speed setting selected by the user. Then, the upper limit of the anti-cold air temperature range is determined based on the upper limit of the temperature range corresponding to this anti-cold air state range. This upper limit of temperature aims to ensure that above this temperature, the air conditioner can operate stably at an appropriate fan speed setting while preventing cold air from being blown out, achieving optimal heating effect and user comfort. In this way, dynamic adjustment and precise control of the anti-cold air temperature upper limit are achieved, enabling the air conditioner to better adapt to the personalized needs of different users and different indoor environmental conditions.

[0080] Optionally, the method further includes: In response to the air conditioner reaching a preset time threshold in the target anti-cold air state range, the anti-cold air state is exited. The speed of the air conditioner's internal fan is adjusted according to the fan speed setting in the heating operation command, and the sweeping blades are controlled to rotate to reduce the angle between the sweeping blades and the air outlet direction.

[0081] In this embodiment, runtime is introduced as a time factor to adjust the speed of the sweeping blades and the indoor fan. Specifically, when the air conditioner has been running in the target anti-cold air state range for a preset time threshold, it usually means that the air conditioner has been running in this state for a period of time. At this point, the speed of the indoor fan will be adjusted accordingly based on the fan speed setting set by the user in the heating operation command, and the sweeping blades will be controlled to rotate, thereby reducing the angle between the sweeping blades and the air outlet direction. This runtime-based adjustment strategy ensures that the air conditioner optimizes the air outlet direction and air volume in a timely manner according to changes in indoor temperature and user comfort needs during long-term operation, thereby further improving the heating effect and user experience. By incorporating runtime as a factor, the air conditioner's control strategy becomes more comprehensive and intelligent, better adapting to different usage scenarios and user needs.
