Description
Technical Field
[0001] This application relates to the field of air conditioning technology, and in particular to an air conditioning control method, device, air conditioner, and storage medium. Background Technology
[0002] Existing air conditioning systems, in heating mode, typically use return air vent temperature sensors to collect indoor ambient temperature and control the compressor's start and stop based on the relationship between the set temperature and the indoor ambient temperature. However, since the indoor unit is usually installed in the upper part of the room, there is a significant height difference between its return air vent and the area where people are active. During heating operation, the difference in density of hot air creates a significant thermal convection effect, resulting in obvious temperature stratification in the indoor space: the temperature near the ceiling is significantly higher than that of the floor, while the temperature sensing point at the return air vent is often in the high-temperature zone, easily causing temperature control distortion. This temperature sensing deviation can cause the system to prematurely terminate heating operation before the actual floor temperature reaches the set value, or continue operating in the high-temperature zone even when it has exceeded the set value, thus causing uneven temperature distribution, such as a significant temperature gradient in the vertical direction of the indoor space, leading to a decrease in human comfort. When the fan speed is low, the high-temperature zone accumulates temperature, and the continuous heating by the air conditioner leads to excessive energy consumption.
[0003] Existing technologies typically use residual heat dissipation to expel heat accumulated in the indoor unit. The duration of residual heat dissipation is controlled by judging the indoor temperature and the downtime. More commonly, a fixed value for the residual heat dissipation duration is set at the factory. This control method based on residual heat dissipation duration can allow the system load to stop relatively stably, but it is difficult to solve the problem of large indoor spaces where heat accumulates in the upper part of the room. In other words, it ignores the temperature stratification caused by differences in indoor space height and cannot adapt to the effects of different space sizes, room heights, and changes in air guide plate angles. Especially in large spaces, it is difficult to effectively and evenly dissipate heat, affecting user comfort. Summary of the Invention
[0004] This application provides an air conditioning control method, device, air conditioner, and storage medium to solve the problems of existing control methods that blow away residual heat according to a fixed preheating time, which ignore the temperature stratification phenomenon caused by the height difference of the indoor space, resulting in temperature perception deviation and excessive energy consumption.
[0005] In a first aspect, this application provides an air conditioning control method, the method comprising: When the indoor ambient temperature reaches the set heating temperature, the corresponding waste heat blowing parameters are determined based on the spatial structure data of the indoor space, wherein the waste heat blowing parameters include a preset waste heat blowing duration. Control the air conditioner to operate according to the aforementioned waste heat blowing parameters; Based on the rate of change of indoor temperature after the air conditioner operates according to the waste heat blowing parameters, the preset waste heat blowing duration is adjusted to obtain the corrected waste heat blowing duration. The air conditioner is controlled to blow away residual heat according to the corrected residual heat blowing duration.
[0006] Optionally, before determining the corresponding waste heat removal parameters based on the spatial structure data of the indoor space when the indoor ambient temperature reaches the set heating temperature, the method further includes: The spatial structure data of the indoor space is detected by the infrared ranging sensor on the air conditioner; or... Based on the floor plan uploaded by the air conditioner's binding terminal, the spatial structure data of the indoor space is determined.
[0007] Optionally, detecting the spatial structure data of the indoor space using an infrared ranging sensor on the air conditioner includes: The infrared distance sensor on the air conditioner's air guide plate detects the ground distance at the first air guide plate angle and the ceiling distance at the second air guide plate angle. Based on the ground detection distance and the angle of the first wind guide plate, determine the first height of the infrared ranging sensor's height line from the ground. Based on the ceiling detection distance and the angle of the second air guide plate, determine the second height of the infrared ranging sensor from the ceiling. The indoor height is determined based on the sum of the first height and the second height; The indoor area is determined by the product of the horizontal distance detected by the infrared ranging sensor and the indoor height, wherein the spatial structure data includes the indoor height and the indoor area.
[0008] Optionally, determining the corresponding waste heat parameters based on the spatial structure data of the indoor space includes: The indoor height and indoor area in the spatial structure data are determined according to the parameter mapping table, and the corresponding preset air guide plate angle and preset fan speed are determined. The parameter mapping table contains the mapping relationship between indoor height, indoor area, air guide plate angle and fan speed. The corresponding heat dissipation coefficient is determined based on the indoor area and the indoor height. The preset waste heat blowing duration is determined based on the product of the heat dissipation coefficient and the indoor area, wherein the waste heat blowing parameters also include the preset air guide plate angle and the preset fan speed.
[0009] Optionally, adjusting the preset waste heat blowing duration based on the rate of change in indoor temperature after the air conditioner operates according to the waste heat blowing parameters to obtain the corrected waste heat blowing duration includes: After the air conditioner operates according to the preset air guide plate angle and the preset fan speed, the indoor ambient temperature is collected periodically according to the preset cycle. The indoor temperature change rate is determined by the ratio of the temperature difference between adjacent indoor ambient temperatures collected to the corresponding duration of the preset period, thus obtaining the first temperature change rate. Based on the duration adjustment scheme corresponding to the rate of change interval to which the first temperature change rate belongs, the remaining duration corresponding to the preset residual heat blowing duration is adjusted to obtain the corrected residual heat blowing duration.
[0010] Optionally, adjusting the remaining time corresponding to the preset waste heat blowing time according to the time adjustment scheme corresponding to the rate of change interval to which the first temperature change rate belongs, to obtain the corrected waste heat blowing time, includes at least one of the following: When the first temperature change rate is within the first change rate range, the remaining time corresponding to the preset residual heat blowing time is shortened according to the time reduction scheme to obtain the corrected residual heat blowing time. When the first temperature change rate falls within the second change rate range, the remaining time corresponding to the preset residual heat blowing time is extended according to the extended duration scheme to obtain the corrected residual heat blowing time, wherein the second change rate range is greater than the first change rate range. When the first temperature change rate falls within the third change rate range, the remaining time corresponding to the preset residual heat blowing time is used as the corrected residual heat blowing time, wherein the third change rate range is located between the first change rate range and the second change rate range.
[0011] Optionally, after controlling the air conditioner to blow away residual heat according to the corrected residual heat blowing duration, the method further includes: The indoor temperature change rate is re-acquired to obtain the second temperature change rate; When the second temperature change rate falls within the fourth change rate range, and the temperature difference corresponding to the second temperature change rate is less than the preset temperature difference, the air conditioner is controlled to stop blowing residual heat.
[0012] Secondly, this application provides an air conditioning control device, the device comprising: The parameter determination module is used to determine the corresponding waste heat blowing parameters based on the spatial structure data of the indoor space when the indoor ambient temperature reaches the set heating temperature. The waste heat blowing parameters include a preset waste heat blowing duration. The control module is used to control the air conditioner to operate according to the waste heat blowing parameters; The correction module is used to adjust the preset waste heat blowing time according to the rate of change of indoor temperature after the air conditioner operates according to the waste heat blowing parameters, so as to obtain the corrected waste heat blowing time. The control module is also used to control the air conditioner to blow away residual heat according to the corrected residual heat blowing duration.
[0013] Thirdly, this application provides an air conditioner, which includes the air conditioner control device as described above.
[0014] Fourthly, this application also provides a computer storage medium storing computer-executable instructions for executing the above-described air conditioning control method.
[0015] Compared with the prior art, the technical solution provided in this application has the following advantages: The method provided in this application, when the indoor ambient temperature reaches the set heating temperature, indicates that the indoor unit of the air conditioner stops heating because the detected temperature above the room has reached the set heating temperature. At this time, the temperature below the room may not have reached the set heating temperature, meaning the heat distribution in the space is uneven. Therefore, it is necessary to use a residual heat blowing method to blow out the heat accumulated in the indoor unit to continue providing heat to the indoor space. Specifically, the corresponding residual heat blowing parameters are determined based on the spatial structure data of the indoor space. The residual heat blowing parameters include a preset residual heat blowing duration, and the air conditioner is controlled to blow out residual heat according to the residual heat blowing parameters. The system operates according to thermal parameters and adjusts the preset residual heat blowing time in real time based on the rate of change of indoor temperature. This results in a corrected residual heat blowing time, which the air conditioner controls to blow residual heat according to the corrected time. This avoids blowing residual heat according to a fixed time. By combining the temperature change rate, the system can sense the uniformity of heat in the space and adjust the residual heat blowing time in real time. This prevents uneven indoor temperature distribution due to insufficient residual heat blowing time and excessive energy consumption due to excessive residual heat blowing time. This solves the problem of temperature perception deviation and excessive energy consumption caused by the existing control method of blowing residual heat according to a fixed preheating time, which ignores the temperature stratification phenomenon caused by the height difference in the indoor space.

[0022] Figure 1 This is a diagram illustrating the application environment of an air conditioning control method in one embodiment. (Refer to...) Figure 1 The air conditioning control method is applied to air conditioner 100, which includes air conditioning control device 110 and infrared ranging sensor 120. The air conditioning control device 110 can be implemented by a controller or an integrated control chip.
[0023] In one embodiment, Figure 2 This is a flowchart illustrating an air conditioning control method in one embodiment, with reference to... Figure 2 This invention provides an air conditioning control method. This embodiment primarily applies this method to the aforementioned... Figure 1 Taking the air conditioning control device 110 as an example, the air conditioning control method specifically includes the following steps: Step S210: When the indoor ambient temperature reaches the set heating temperature, determine the corresponding waste heat blowing parameters based on the spatial structure data of the indoor space, wherein the waste heat blowing parameters include a preset waste heat blowing duration.
[0024] Specifically, the indoor ambient temperature is detected by the temperature sensor on the air conditioner 100. The temperature sensor is usually located near the air inlet or outlet of the air conditioner 100. When the indoor ambient temperature reaches the set heating temperature, it means that the air conditioner 100 will no longer continue to heat. However, at this time, there may be heat accumulation and higher temperature in the upper part of the room, while there is less heat and lower temperature in the lower part of the room near the ground. That is, the heat distribution in the room is uneven. In order to solve the problem of uneven heat distribution in the room, it is necessary to blow out the heat accumulated in the indoor unit of the air conditioner 100 to continue to provide heat to the room.
[0025] Specifically, the operating parameters for waste heat dissipation are determined based on the room's spatial structure data. These parameters include the preset waste heat dissipation duration, air guide plate angle, and fan speed. The preset waste heat dissipation duration can be fixed or dynamically matched based on the spatial structure data. Matching the optimal preset waste heat dissipation duration to the actual room structure data ensures that the problem of uneven heat distribution between the upper and lower levels of the room is not effectively addressed due to an insufficiently short preset duration, resulting in incomplete heat dissipation and a noticeable temperature difference for users in the lower part of the room, leading to a poor experience. Conversely, an excessively long preset duration will not cause excess cooling to be drawn into the room, resulting in a drop in overall room temperature and wasted energy. This approach effectively improves uneven heat distribution within a reasonable energy consumption range, enhancing user comfort.
[0026] Step S220: Control the air conditioner 100 to operate according to the waste heat blowing parameters.
[0027] Specifically, the air conditioner 100 is controlled to operate according to the waste heat blowing parameters in order to blow out the accumulated heat in the indoor unit of the air conditioner 100. The waste heat blown out according to the waste heat blowing parameters is used to change the heat distribution state in the indoor space, breaking the phenomenon of heat accumulation at the top of the room and thin heat at the bottom of the room.
[0028] Step S230: Based on the rate of change of indoor temperature after the air conditioner 100 operates according to the residual heat blowing parameters, adjust the preset residual heat blowing time to obtain the corrected residual heat blowing time.
[0029] Specifically, after the air conditioner 100 operates according to the waste heat dissipation parameters, the indoor air temperature field is not static, but undergoes complex convection and heat conduction. The indoor temperature change rate is acquired in real-time or at regular intervals. This rate includes the temperature change rate at at least one sampling point at different sampling times. These sampling points are located at different heights and / or heights within the indoor space. Specific sampling points can be the air outlet of the air conditioner 100, the return air outlet of the air conditioner 100, or other connected home appliances or temperature sensors with temperature acquisition capabilities. Connected home appliances can include smart refrigerators, smart washing machines, smart TVs, smart speakers, smart curtains, etc. The indoor temperature change rate indicates the distribution of indoor hot air because it reflects the rate of heat exchange between local air and the surrounding environment (including walls, furniture, and the air itself). If the indoor hot air distribution is uneven, the temperature difference between different areas will be greater, leading to inconsistent heat exchange rates, which manifests as differences in the temperature change rate.
[0030] If hot air is distributed roughly evenly throughout a room, with minimal temperature differences, then the air in the entire room acts like a single entity, dissipating heat at a similar rate to cool surfaces such as walls, windows, and furniture, causing the temperature to drop synchronously and steadily. In this case, the rate of temperature change (dT / dt) measured at different locations (such as the center and corners of the room, the ceiling and the floor) will be essentially the same. If there are significant differences in the rate of temperature change at different heights or horizontal positions within the room, it indicates that the hot air is not distributed evenly.
[0031] The uniformity of indoor hot air distribution is determined by the rate of change of indoor temperature after the residual heat is blown out. Then, the preset residual heat blowing time is adjusted based on the uniformity of indoor hot air distribution. The adjustment methods include extending, shortening or maintaining. That is, the preset residual heat blowing time is extended, shortened or maintained according to the uniformity of indoor hot air distribution. Thus, the appropriate residual heat blowing time is determined according to the actual uniformity of hot air distribution, which is the corrected residual heat blowing time. This avoids energy waste due to excessive residual heat blowing time and insufficient residual heat blowing due to insufficient residual heat blowing time, resulting in uneven distribution of hot air in the indoor space.
[0032] Step S240: Control the air conditioner 100 to blow away residual heat according to the corrected residual heat blowing duration.
[0033] Specifically, the air conditioner 100 is controlled to operate according to the residual heat blowing parameters, and the preset residual heat blowing time is corrected in real time according to the indoor temperature change rate, thereby obtaining the corrected residual heat blowing time. The air conditioner 100 blows residual heat according to the real-time corrected residual heat blowing time, avoiding blowing residual heat according to a fixed residual heat blowing time. In addition, the uniformity of heat in the space can be sensed by combining the temperature change rate. This solves the problem that the existing control method of blowing residual heat according to a fixed preheating time ignores the temperature stratification phenomenon caused by the height difference of the indoor space, resulting in temperature perception deviation and excessive energy consumption.
[0034] In one embodiment, refer to Figure 4 Before determining the corresponding waste heat removal parameters based on the spatial structure data of the indoor space when the indoor ambient temperature reaches the set heating temperature, the method further includes: The spatial structure data of the indoor space is detected by the infrared ranging sensor 120 on the air conditioner 100; or, Based on the floor plan uploaded by the binding terminal of the air conditioner 100, the spatial structure data of the indoor space is determined.
[0035] Specifically, spatial structure data includes indoor height, indoor width, and indoor area. This data can be obtained by detecting and acquiring the spatial structure of the indoor space using an infrared ranging sensor 120, or by determining the spatial structure data based on a floor plan uploaded by the user. Alternatively, the installation location of the air conditioner 100 can be used to determine the building area, and then the floor plan of that building area can be obtained from the network. Based on the floor plan, the corresponding spatial structure data can be determined. For example, the installation location of the air conditioner 100 can determine whether the building area is an office building, residential building, or commercial building. Assuming the building area is a residential building, the installation space of the air conditioner 100 within that building can be determined based on the installation location, i.e., the target apartment number of the air conditioner 100 in the residential building can be determined based on the installation location; then, the corresponding floor plan can be obtained based on its installation space, i.e., the corresponding floor plan can be obtained based on the target apartment number; and finally, the corresponding spatial structure data can be determined based on the floor plan.
[0036] Compared to solutions relying on on-site measurements, this data acquisition method eliminates the complex process of installing sensors on-site. Data retrieval can be completed quickly after the Air Conditioner 100 is installed and positioned, improving overall data acquisition efficiency. Furthermore, relying on standardized floor plan data from publicly available real estate buildings, the obtained spatial structure data has a smaller error margin, far below the common error range of manual measurements. This not only meets the accuracy requirements of the Air Conditioner 100's automatic adjustment of air supply parameters and operating power but also solves the data distortion problem caused by users' misinterpretation of floor plan annotations or manual data input errors when uploading their own floor plans. This provides stable and reliable basic data support for the subsequent intelligent operation of the Air Conditioner 100.
[0037] In one embodiment, detecting the spatial structure data of the indoor space via the infrared ranging sensor 120 on the air conditioner 100 includes: The infrared distance sensor 120 on the air guide plate of the air conditioner 100 detects the ground detection distance at the first air guide plate angle and the ceiling detection distance at the second air guide plate angle. Based on the ground detection distance and the angle of the first wind guide plate, determine the first height of the infrared ranging sensor 120 from the ground. Based on the ceiling detection distance and the angle of the second air guide plate, determine the second height of the infrared ranging sensor 120 from the ceiling. The indoor height is determined based on the sum of the first height and the second height; The indoor area is determined by the product of the horizontal distance detected by the infrared ranging sensor 120 and the indoor height, wherein the spatial structure data includes the indoor height and the indoor area.
[0038] Specifically, refer to Figure 3 Since the infrared ranging sensor 120 is located on the air guide plate of the air conditioner 100, the acquisition angle of the infrared ranging sensor 120 can be changed by rotating the air guide plate. The first air guide plate angle... This refers to the angle between the emitted wave from the infrared ranging sensor 120 towards the ground and the horizontal line where the air conditioner 100 is located. In other words, the angle of the first air guide plate can be any angle below the horizontal line where the air conditioner 100 is located. The angle of the first air guide plate is detected by the infrared ranging sensor 120. The ground detection distance L1 of the emitted wave reaching the ground can be used to calculate the first height H1 of the horizontal line where the air conditioner 100 is located from the ground.
[0039] Second air guide plate angle This refers to the angle between the emitted wave from the infrared ranging sensor 120 towards the ceiling and the horizontal line where the air conditioner 100 is located. In other words, the angle of the second air guide plate can be any angle above the horizontal line where the air conditioner 100 is located. The angle of the second air guide plate is detected by the infrared ranging sensor 120. The ceiling detection distance L2 of the emitted wave reaching the ceiling can be used to calculate the second height H2 of the horizontal line where the air conditioner 100 is located from the ceiling.
[0040] The indoor height can be accurately determined by the sum of the first and second heights, i.e., indoor height H = H1 + H2. This height calculation method relies entirely on the mechanical structure of the existing rotatable air guide plate of the air conditioner 100 to complete the detection angle adjustment. It does not require additional height detection sensors or complex gimbal rotation modules, thus avoiding additional installation space inside the air conditioner 100 and significantly increasing the hardware production cost of the air conditioner 100. At the same time, combined with the high-precision rotation control accuracy of the air guide plate itself, it can ensure the accuracy of height calculation. Compared with traditional methods that rely on manual measurement of indoor height or additional ranging solutions such as ultrasonic sensors, the infrared ranging sensor 120 is less affected by ambient temperature and humidity and air noise interference. It can stably output accurate detection values in various home environments where the air conditioner 100 is used daily, without significant measurement errors due to indoor obstructions or uneven wall reflections. In addition, the calculation process can be automatically triggered after the air conditioner 100 is installed, without the need for the installer to perform additional manual measurement operations. This reduces the workload of the installer and provides accurate spatial data support for the air conditioner 100 to adjust the air supply parameters and optimize the temperature control effect according to the actual indoor space. This allows the air supply range and cooling and heating speed of the air conditioner 100 to be more adapted to the actual indoor space size, thus improving the user experience.
[0041] In one embodiment, refer to Figure 4 The step of determining the corresponding waste heat parameters based on the spatial structure data of the indoor space includes: The indoor height and indoor area in the spatial structure data are determined according to the parameter mapping table, and the corresponding preset air guide plate angle and preset fan speed are determined. The parameter mapping table contains the mapping relationship between indoor height, indoor area, air guide plate angle and fan speed. The corresponding heat dissipation coefficient is determined based on the indoor area and the indoor height. The preset waste heat blowing duration is determined based on the product of the heat dissipation coefficient and the indoor area, wherein the waste heat blowing parameters also include the preset air guide plate angle and the preset fan speed.
[0042] Specifically, the parameter mapping table includes the mapping relationship between indoor height, indoor area, air guide vane angle, and fan speed. Generally, the higher the indoor height and the larger the indoor area, the more the air guide vane angle is towards the ground and the faster the fan speed. This is used to accelerate the blowing of residual heat towards the ground in high-ceilinged and large rooms, allowing hot air to be quickly transferred to the lower part of the room. When the room height is low, the air outlet angle is adjusted to be smaller, that is, closer to the horizontal line, with the angle controlled at 15-20 degrees downward. This allows the airflow speed to decrease by the time it reaches above a person's head, and then gently diffuses in all directions, not blowing directly on the user's head. Indoor height H is the resistance source, fan speed n is the power source, and air guide vane angle θ is the direction controller. The three must be matched. n increases with the square root of H, while θ... 15° to The optimal balance point is found within 30° to maximize the vertical momentum component. The first step is to adjust the angle, setting the air deflector to the optimal angle for high-ceilinged scenarios, determined through experiments, which ensures both downward descent and a certain degree of horizontal diffusion. Then, the fan speed is adjusted.
[0043] To overcome the buoyancy resistance caused by the indoor height H and achieve effective coverage, the fan speed n must provide sufficient initial kinetic energy. The guide vane angle θ (the angle between the initial airflow velocity and the horizontal plane (negative downwards, positive upwards)) is responsible for efficiently converting this kinetic energy into a downward vertical component. If H increases: to maintain the same coverage effect, n must be increased, or sin(∣α∣) must be increased, i.e., the guide vane must be pressed lower. If θ is adjusted, it is usually in... 15° to Between 30°, the vertical component is large enough to counteract buoyancy while retaining sufficient horizontal momentum for diffusion. Since the rotational speed cannot be increased indefinitely (limited by noise or motor power), sin(∣θ∣) needs to be increased, i.e., the air guide plate needs to be adjusted lower.
[0044] Increasing the fan speed primarily utilizes the principles of momentum transfer and turbulent mixing. Increasing the fan speed directly increases the airflow velocity (v) at the outlet. According to the kinetic energy formula Ek=1 / 2mv*v, the kinetic energy carried by the airflow increases significantly. As the Reynolds number increases, the airflow transitions from laminar to turbulent. Turbulence implies the presence of strong eddies and pulsations within the fluid. This intense disturbance disrupts the previously stable "thermal stratification" interface, forcibly drawing down the hot air from the top and rapidly mixing it with the cool air from the bottom. Through mechanical agitation, the air temperature distribution throughout the room tends to be more uniform, reducing the vertical temperature gradient.
[0045] Adjusting the air deflector essentially changes the initial projection angle and trajectory of the airflow. Adjusting the deflector downwards (e.g., -15° to -30°) creates a downward vertical component in the initial velocity vector of the airflow. This downward momentum component directly counteracts the upward buoyancy caused by gravity, forcing the airflow to reach the vicinity of the ground first. When the high-speed airflow blows downwards at a certain angle, it impacts the ground or near-ground objects. The impacted airflow then diffuses horizontally along the ground, forming a "thermal pad" covering the floor. Simultaneously, due to the presence of the room's side walls, the diffused airflow rises along the walls, eventually forming a circulation loop in the upper part of the room. This large circulation pattern of "downward pressure - diffusion - rising along the walls - top return" ensures that hot air reaches every corner of the room. If the angle is too vertically downwards, the airflow may directly impact the ground and bounce, causing localized noise and dead zones. Theoretically, the optimal angle is usually angled downwards, allowing the airflow to maintain a certain horizontal velocity before reaching the ground, thereby expanding the coverage radius and preventing heat from concentrating in a small area directly below the air conditioner.
[0046] Therefore, by querying the parameter mapping table, the preset air guide plate angle and preset fan speed corresponding to the detected indoor area and indoor height can be determined, thereby determining the waste heat blowing method that matches the size of the indoor space.
[0047] It also uses the mapping relationship between indoor area, indoor height, and heat dissipation coefficient to query the heat dissipation coefficient that matches the current room type. The heat dissipation coefficient is directly proportional to the space size and is used to indicate heat diffusion efficiency, generally ranging from 0.2 to 0.6. The initial preset residual heat dissipation time is determined by multiplying the heat dissipation coefficient matching the current indoor space by the indoor area. Where k is the heat dissipation coefficient and A is the indoor area. This calculation method allows the preset residual heat blowing time to dynamically adapt to the heat diffusion requirements of the indoor space: when the indoor area is larger and the heat dissipation coefficient is higher, the preset residual heat blowing time will be extended accordingly, ensuring that the residual heat in the heat exchange pipes of the air conditioner can be completely blown out, avoiding the accumulation of residual heat inside the pipes and causing energy waste, and also avoiding the initial air outlet carrying excess heat when the cooling mode is turned on next time, which would cause indoor temperature fluctuations; when the indoor area is smaller and the required heat diffusion is lower, the preset residual heat blowing time will be shortened accordingly, which can avoid unnecessary air supply consuming extra power, and also avoid excessive heat dissipation into the room due to an excessively long residual heat blowing process, causing user discomfort.
[0048] The waste heat blowing parameters determined by this method ensure that the waste heat blowing process of the air conditioner always matches the actual needs of the current indoor space. Compared with the waste heat blowing control mode with fixed parameters, the sufficiency of waste heat blowing and the operating energy efficiency can be significantly improved. There will be no heat residue caused by insufficient waste heat blowing, nor will there be energy waste and physical discomfort caused by excessive waste heat blowing.
[0049] In one embodiment, refer to Figure 4 The step of adjusting the preset waste heat blowing duration based on the rate of change of indoor temperature after the air conditioner 100 operates according to the waste heat blowing parameters, to obtain the corrected waste heat blowing duration, includes: After the air conditioner 100 operates according to the preset air guide plate angle and the preset fan speed, the indoor ambient temperature is collected periodically according to the preset cycle. The indoor temperature change rate is determined by the ratio of the temperature difference between adjacent indoor ambient temperatures collected to the corresponding duration of the preset period, thus obtaining the first temperature change rate. Based on the duration adjustment scheme corresponding to the rate of change interval to which the first temperature change rate belongs, the remaining duration corresponding to the preset residual heat blowing duration is adjusted to obtain the corrected residual heat blowing duration.
[0050] Specifically, the preset period can be a fixed duration, such as 5 seconds, 10 seconds, or 1 minute, or it can be determined by combining the indoor area and indoor height. That is, the larger the indoor area and the higher the indoor height, the longer the corresponding preset period, and vice versa. Different indoor heights and indoor areas correspond to different preset periods. In this embodiment, a preset period of 5 seconds is used as an example. After the air conditioner 100 blows away residual heat according to the preset air guide plate angle and preset fan speed, the indoor ambient temperature is collected every 5 seconds. The indoor ambient temperature can be the temperature collected at any point in the indoor space, the lowest temperature among multiple collected temperatures, or the average temperature of multiple collected temperatures.
[0051] The indoor ambient temperature collected in adjacent cycles refers to the indoor ambient temperature collected at two different times consecutively. The rate of change of indoor temperature is determined based on the ratio between the temperature difference between the indoor ambient temperatures collected in adjacent cycles and the corresponding duration of the preset cycle. That is, the rate of change of indoor temperature is denoted as ΔT / Δt, where ΔT is the temperature difference between the indoor ambient temperatures collected in adjacent cycles and Δt is the corresponding duration of the preset cycle. The indoor temperature change rate calculated at this time is denoted as the first rate of change of temperature.
[0052] The first temperature change rate is used to reflect the heat diffusion effect in the room after the air conditioner 100 blows out residual heat. The remaining time corresponding to the preset residual heat blowing time is dynamically adjusted in real time according to the first temperature change rate to obtain the corrected residual heat blowing time. This allows the residual heat to be blown out according to the corrected residual heat blowing time, thereby avoiding uneven heat distribution in the indoor space due to insufficient residual heat blowing, i.e., more heat at the top and less heat at the bottom. It can also avoid resource waste caused by excessive residual heat blowing time.
[0053] The scheme of dynamically adjusting the duration of waste heat blowing based on the first temperature change rate can achieve closed-loop adaptive control of the waste heat blowing process. Compared with the fixed duration waste heat blowing scheme, it is suitable for the waste heat blowing needs of rooms with different apartment types and different initial heat distribution states: For rooms where the initial heat diffusion has been completed and the temperature gradient is small, the first temperature change rate will quickly fall into the low change rate range, and the system will trigger the adjustment scheme of early termination of waste heat blowing. Compared with the fixed duration scheme, it can shorten the ineffective running time on average and reduce the useless power consumption of the compressor before standby. For large spaces and rooms with serious initial heat accumulation, the first temperature change rate will remain in the high change rate range, indicating that the heat has not yet been evenly diffused. The system will automatically extend the waste heat blowing duration. Compared with the fixed duration scheme, it can reduce the temperature difference between the lower and upper areas of the room within 1 hour after the air conditioner is turned off, significantly improving the thermal comfort of the user's activity area after the air conditioner is turned off. At the same time, it avoids the accumulation of residual heat in the outdoor unit condenser due to insufficient heat diffusion and extends the service life of the outdoor unit heat exchange components.
[0054] In one embodiment, adjusting the remaining time corresponding to the preset waste heat blowing time according to the time adjustment scheme corresponding to the rate of change interval to which the first temperature change rate belongs, to obtain the corrected waste heat blowing time, includes at least one of the following: When the first temperature change rate is within the first change rate range, the remaining time corresponding to the preset residual heat blowing time is shortened according to the time reduction scheme to obtain the corrected residual heat blowing time. When the first temperature change rate falls within the second change rate range, the remaining time corresponding to the preset residual heat blowing time is extended according to the extended duration scheme to obtain the corrected residual heat blowing time, wherein the second change rate range is greater than the first change rate range. When the first temperature change rate falls within the third change rate range, the remaining time corresponding to the preset residual heat blowing time is used as the corrected residual heat blowing time, wherein the third change rate range is located between the first change rate range and the second change rate range.
[0055] Specifically, the first rate of change interval, the second rate of change interval, and the third rate of change interval can be customized according to the actual application scenario, but they must meet the condition that the first rate of change interval is less than the third rate of change interval, and the third rate of change interval is less than the second rate of change interval. In this embodiment, the first rate of change interval is a numerical range of less than 0.1°C / min, the second rate of change interval is a numerical range of greater than 0.3°C / min, and the third rate of change interval is [0.1, 0.3].
[0056] If |ΔT / Δt| < 0.1°C / min, meaning the first temperature change rate falls within the first change rate range, then the remaining time corresponding to the preset waste heat blowing time is reduced according to the time reduction scheme. The remaining time corresponding to the preset waste heat blowing time refers to the time remaining from the end of the preset waste heat blowing time after the waste heat is blown according to the preset time. Specifically, the time reduction scheme can be to subtract a preset time step from the remaining time corresponding to the preset waste heat blowing time, or to multiply the remaining time corresponding to the preset waste heat blowing time by a reduction coefficient. The preset time step and reduction coefficient can be fixed values, or values determined based on the indoor area and indoor height. In this embodiment, the reduction coefficient is set to 0.7, and the preset time step is 3 minutes, then the corrected waste heat blowing time is... ,or , This is the remaining time corresponding to the preset waste heat blowing time.
[0057] If |ΔT / Δt|>0.3°C / min, meaning the first temperature change rate falls within the second change rate range, then the remaining time corresponding to the preset waste heat blowing time is extended according to the extended duration scheme. Specifically, the extended duration scheme can be achieved by adding a preset time step to the remaining time corresponding to the preset waste heat blowing time, or by multiplying the remaining time corresponding to the preset waste heat blowing time by an extension factor. The preset time step and extension factor can be fixed values, or values determined based on the indoor area and indoor height. In this embodiment, the extension factor is set to 1.2, therefore the corrected waste heat blowing time is... ,or .
[0058] If 0.1≤|ΔT / Δt|≤0.3, meaning the first temperature change rate belongs to the third change rate range, then continue the waste heat blowing process according to the preset waste heat blowing time until the end time corresponding to the preset waste heat blowing time is reached.
[0059] This technology, which dynamically adjusts the duration of waste heat blowing based on the actual rate of temperature change, effectively avoids ineffective waste heat blowing in scenarios where the temperature drops slowly, thus reducing the power consumption of the air conditioner 100. It also avoids the problem of compressor starting with liquid due to insufficient waste heat blowing in scenarios where the temperature drops too quickly. This not only improves the energy efficiency of the air conditioner 100 but also extends the service life of core refrigeration components such as the compressor.
[0060] In one embodiment, after controlling the air conditioner 100 to blow away residual heat according to the corrected residual heat blowing duration, the method further includes: The indoor temperature change rate is re-acquired to obtain the second temperature change rate; When the second temperature change rate falls within the fourth change rate range, and the temperature difference corresponding to the second temperature change rate is less than the preset temperature difference, the air conditioner 100 is controlled to stop blowing residual heat.
[0061] Specifically, after the air conditioner 100 performs waste heat treatment according to the corrected waste heat blowing duration, the temperature is re-collected to calculate the indoor temperature change rate, resulting in a second temperature change rate. The fourth change rate range is smaller than the first change rate range. In this embodiment, the fourth change rate range is set to a value range less than 0.5°C / min. If |ΔT / Δt| < 0.05°C / min and ΔT < ΔT0, where ΔT0 is the preset temperature difference, it indicates that the indoor temperature change rate is small and the indoor temperature fluctuation does not exceed the preset temperature difference. At this time, the indoor heat distribution is uniform and meets the comfort requirements. Therefore, the waste heat blowing operation is terminated, i.e., the air conditioner 100 is forcibly shut down. This determination method relies on real-time temperature acquisition and rate of change calculation technology to accurately capture the stable state of the indoor temperature field. It avoids leaving residual heat in corners due to premature shutdown, causing users to feel stuffy and uncomfortable, and also avoids unnecessary energy waste due to excessively prolonged residual heat blowing time. Compared with the traditional fixed-duration residual heat blowing control scheme, this technology can improve indoor temperature uniformity, reduce the average energy consumption of a single residual heat blowing process, and avoid unnecessary wear and tear on internal fan components caused by the air conditioner running 100% idling for a long time, thus extending the overall service life of the equipment.

[0067] In one embodiment, the correction module 330 is further configured to: After the air conditioner 100 operates according to the preset air guide plate angle and the preset fan speed, the indoor ambient temperature is collected periodically according to the preset cycle. The indoor temperature change rate is determined by the ratio of the temperature difference between adjacent indoor ambient temperatures collected to the corresponding duration of the preset period, thus obtaining the first temperature change rate. Based on the duration adjustment scheme corresponding to the rate of change interval to which the first temperature change rate belongs, the remaining duration corresponding to the preset residual heat blowing duration is adjusted to obtain the corrected residual heat blowing duration.
[0068] In one embodiment, the correction module 330 is further configured to perform at least one of the following: When the first temperature change rate is within the first change rate range, the remaining time corresponding to the preset residual heat blowing time is shortened according to the time reduction scheme to obtain the corrected residual heat blowing time.
