Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning control method, an air conditioner and a computer-readable storage medium. Background Art

[0002] With the development of economy and technology, the application of air conditioners is becoming more and more extensive, and the performance of air conditioners is also being continuously optimized. Among them, air conditioners generally have a cold wind prevention function when heating. During the implementation of the cold wind prevention function, the air conditioner will increase the speed of the internal fan as the indoor coil temperature increases after the heating is started, and will reduce the speed of the internal fan as the indoor coil temperature decreases.

[0003] However, when the target air conditioner increases the fan speed during the cold wind prevention stage, the fan speed is generally adjusted according to a pre-set fixed rate. Under different working conditions, the fixed rate is prone to be too large or too small. A large rate will cause the coil temperature to drop too quickly after the fan speed is increased, and the frequent speed changes of the fan will affect the heating of the indoor environment. A small rate will cause the heat to fail to be delivered to the room for a long time, which is also difficult to ensure the heating effect of the air conditioner. It can be seen that the current air conditioner has a poor heating effect during the cold wind prevention stage. Summary of the invention

[0015] Optionally, after the step of obtaining the temperature of the indoor heat exchanger when the air conditioner is in the heating state, the method further includes:

[0016] When the temperature of the indoor heat exchanger is lower than the first temperature threshold and higher than the second temperature threshold, controlling the indoor fan to operate at a first speed;

[0017] When the temperature of the indoor heat exchanger is lower than the second temperature threshold, controlling the indoor fan to stop;

[0018] The step of controlling the indoor fan to increase the speed according to the target adjustment rate comprises:

[0020] The first rotation speed is smaller than the second rotation speed, and the first temperature threshold is larger than the second temperature threshold.

[0021] Optionally, the air conditioning control method further includes: acquiring the first temperature threshold and / or the second temperature threshold according to a temperature change trend of the indoor heat exchanger and an outdoor ambient temperature.

[0022] Optionally, the step of acquiring the first temperature threshold and / or the second temperature threshold according to the temperature change trend of the indoor heat exchanger and the outdoor ambient temperature includes:

[0023] Acquire a first set temperature threshold and / or a second set temperature threshold according to the temperature change trend, and determine a temperature correction value according to the outdoor ambient temperature;

[0024] Correcting the first set temperature threshold according to the temperature correction value to obtain the first temperature threshold, and / or correcting the second set temperature threshold according to the temperature correction value to obtain the second temperature threshold;

[0025] The first set temperature threshold is greater than the second set temperature threshold.

[0026] Optionally, the step of determining the temperature correction value according to the outdoor ambient temperature includes:

[0027] When the outdoor ambient temperature is greater than or equal to a preset ambient temperature, determining the preset ambient temperature as the temperature correction value;

When the air-conditioning control program is executed by a processor, the steps of the air-conditioning control method as described in any one of the above items are implemented.

[0033] The present invention proposes an air conditioning control method. During the heating operation of the air conditioner, the method increases the indoor fan speed when the temperature of the indoor heat exchanger is greater than or equal to a first temperature threshold, so as to avoid a large amount of cold air being sent into the room when the coil temperature is insufficient. In the process of increasing the indoor fan speed, the increase rate is not pre-set, but changes according to the change of the indoor ambient temperature. Based on this, it can be ensured that the increase rate of the indoor fan speed can be accurately matched with the current working conditions, and the increase rate will not be too large or too small, so as to ensure that the hot air can be sent into the room in time. At the same time, the heat exchange efficiency of the indoor heat exchanger can be matched with the actual heating efficiency of the air conditioner, thereby avoiding the cold wind blowing on people while improving the heating effect of the air conditioner on the indoor environment.

[0042] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0043] The main solution of the embodiment of the present invention is: when the air conditioner is in the heating state, the indoor heat exchanger temperature is obtained; when the indoor heat exchanger temperature is greater than or equal to the first temperature threshold, the target adjustment rate of the indoor fan is determined according to the indoor ambient temperature; different indoor ambient temperatures correspond to different target adjustment rates; according to the target adjustment rate, the indoor fan is controlled to increase the speed.

[0044] In the prior art, when the target air conditioner increases the fan speed during the cold wind prevention stage, the fan speed is generally adjusted according to a preset fixed rate. Under different working conditions, the fixed rate is prone to be too large or too small. A large rate will cause the coil temperature to drop too quickly after the fan speed is increased, and the frequent speed change of the fan will affect the heating of the indoor environment. A small rate will cause the heat to fail to be delivered to the room for a long time, which is also difficult to ensure the heating effect of the air conditioner. It can be seen that the current air conditioner has a poor heating effect during the cold wind prevention stage.

[0045] The present invention provides the above-mentioned solution, aiming to prevent cold wind from blowing on people while improving the heating effect of the air conditioner on the indoor environment.

[0046] The embodiment of the present invention provides an air conditioner, which may be a wall-mounted air conditioner, a floor-standing air conditioner, a window air conditioner, a ceiling-mounted air conditioner, a mobile air conditioner, etc.

[0047] In the embodiment of the present invention, refer to Figure 1 and Figure 2 The air conditioner is a floor-standing air conditioner. Specifically, the air conditioner includes a housing 1, an indoor heat exchanger 7 and an indoor fan 2. The housing 1 is provided with a return air port and an air outlet, and the air outlet is extended along the height direction of the housing. The number of air outlets can be one or more according to actual needs. In this embodiment, there are two air outlets, which are arranged at intervals along the lateral direction of the air conditioner.

[0048] An air duct connecting the return air port and the air outlet may be provided in the housing 1, and the indoor fan 2 and the indoor heat exchanger 7 are both provided in the air duct. When the indoor fan 2 is running, the air in the indoor environment may enter the air duct from the return air port and undergo heat exchange through the indoor heat exchanger 7, and the airflow after heat exchange through the indoor heat exchanger 7 is sent into the indoor environment from the air outlet.

[0049] Further, see Figure 1 and Figure 2 The air outlet may be provided with a switch door 01, and the edge of the air outlet located on the outer surface of the housing 1 can be opened or blocked by changing the position of the switch door 01. When the switch door 01 is in the open position to open the air outlet, the airflow in the housing 1 can be sent into the indoor environment from the air outlet; when the switch door 01 is in the closed state, the airflow in the housing 1 cannot be sent into the indoor environment from the air outlet.

[0050] Reference Figure 2 The air conditioner further comprises an air guide assembly 3, which is arranged on the housing 1 and corresponds to the air outlet. Specifically, the air guide assembly 3 comprises an air dispersion plate and a swirl module arranged on the air dispersion plate, and the air dispersion plate is provided with a plurality of air dispersion holes. Specifically,

[0051] The air dispersion plate includes a first air dispersion plate 31 and a second air dispersion plate 32. The first air dispersion plate 31 and the second air dispersion plate 32 are both provided with a plurality of air dispersion holes. The airflow passing through the first air dispersion plate 31 and the second air dispersion plate 32 can be dispersed by the air dispersion holes. The air dispersion holes can be grille holes, micro holes or mesh holes. The first air dispersion plate 31 and the second air dispersion plate 32 are both rotatably connected to the housing 1 to open or cover the air outlet.

[0052] The relative position between the second air dispersing plate 32 and the first air dispersing plate 31 is fixed, and as the position of the first air dispersing plate 31 changes, the position of the second air dispersing plate 32 will change along with the first air dispersing plate 31. The first air dispersing plate 31 and the second air dispersing plate 32 may be connected to the housing 1 via the same rotating shaft, and the rotating shaft is extended along the height direction of the housing 1. Based on the different rotation positions of the second air dispersing plate 32 and the first air dispersing plate 31, their positions relative to the air outlet are different, and thus the air guiding states of the air guide assembly 3 are different.

[0053] In this embodiment, the wind guide component 3 has a first wind guide state and a second wind guide state, and the wind guide component 3 can be switched between the first wind guide state and the second wind guide state by rotation. The wind speed of the wind outlet corresponding to the first wind guide state is less than or equal to the set wind speed, and the wind speed of the wind outlet corresponding to the second wind guide state is greater than the set wind speed.

[0054] In the first wind guiding state, the first wind dispersing plate 31 and the second wind dispersing plate 32 are in the first wind guiding position and cooperate to block the air outlet. The first wind guiding position is specifically that the first wind dispersing plate 31 blocks the air outlet, and the second wind dispersing plate 32 is located in the shell 1 in a wind-blocking state. At this time, the second wind dispersing plate 32 blocks the airflow blowing from the shell 1 to the first wind dispersing plate 31. When the first wind dispersing plate 31 completely blocks the air outlet, the edge of the first wind dispersing plate 31 closes the edge of the air outlet, and all airflow is sent into the room through the first wind dispersing plate 31. Based on this, the airflow that needs to be sent into the room from the air outlet after heat exchange by the indoor heat exchanger 7 is first dispersed through the wind holes on the second wind dispersing plate 32, and then further dispersed through the wind holes of the first wind dispersing plate 31 before being sent into the room. At this time, the air conditioner has a smaller air volume and wind speed, and the wind feeling felt by the user is weaker.

[0055] In the second wind guiding state, the second wind dispersing plate 32 and the first wind dispersing plate 31 are in the second wind guiding position and the air outlet is opened. Specifically, the second wind dispersing plate 31 and the second wind dispersing plate 32 are both located in the housing 1, the second wind dispersing plate 32 is spaced apart from the edge of the air outlet, and the first wind dispersing plate 31 is located on the inner side of the second wind dispersing plate 32. At this time, the first wind dispersing plate 31 and the second wind dispersing plate 32 cooperate to open the air outlet, and the airflow in the housing 1 is sent into the indoor environment from the gap between the second wind dispersing plate 32 and the edge of the air outlet. It should be noted that the distance between the first wind dispersing plate 31 and the air outlet is greater than the distance between the second wind dispersing plate 32 and the air outlet. Based on this, a small part of the airflow that needs to be sent into the room from the air outlet after heat exchange of the indoor heat exchanger 7 can be sent into the room after being dispersed by two wind dispersing plates, and most of it is directly sent into the room from the gap between the second wind dispersing plate 32 and the air outlet. At this time, the air conditioner has a large air volume and wind speed, and the user feels a strong wind feeling.

[0056] The first air dispersing plate 31 and the second air dispersing plate 32 can be set as a flat plate structure or a curved surface structure with an arc surface according to actual needs. Specifically, in this embodiment, the two oppositely arranged plate surfaces of the first air dispersing plate 31 are defined as wind guide surfaces, and the wind guide surface of the first air dispersing plate 31 is a curved surface convex toward a direction away from the second air dispersing plate 32, which is conducive to reducing the wind feeling while increasing the wind outlet area.

[0057] Specifically, in one embodiment of the air conditioner, the edge of the first air dispersion plate 31 can be connected to the edge of the second air dispersion plate 32, and the plate surfaces of the two air dispersion plates are enclosed to form a guide cavity. Based on this, when the first air dispersion plate 31 is in a state of blocking the air outlet, the airflow dispersed by the second air dispersion plate 32 can be completely gathered in the guide cavity and then sent into the room from the first air dispersion plate 31, ensuring that the two air dispersion plates cooperate to reduce the wind speed at the air outlet while ensuring sufficient cooling output at the air outlet through the convergence effect.

[0058] Further, see Figure 3 In addition to the air dispersion holes, the second air dispersion plate 32 may also be provided with ventilation holes. The aperture of the ventilation holes is larger than that of the air dispersion holes. Specifically, the ventilation holes may be provided with a swirl module, a grille or a mesh, etc., or may be left empty. In this embodiment, there are multiple ventilation holes, each of which is provided with a swirl module. The swirl module is used to disperse the passing airflow and blow it out from all sides when rotating.

[0059] In this embodiment, the air guide assembly may also include a swirl module 4, which may be arranged on the second air dispersing plate 32 and / or the first air dispersing plate 31 according to actual needs, specifically, between the first air dispersing plate 31 and the second air dispersing plate 32 or on the side of the first air dispersing plate 31 away from the second air dispersing plate 32. The swirl module 4 includes a turntable, which may be provided with swirl blades, grilles or meshes. When the swirl module 4 rotates, the airflow blown toward the air outlet in the housing 1 or the airflow flowing through the air outlet may be dispersed to the surroundings to further reduce the air outlet speed of the air outlet; and when the swirl module 4 stops rotating, the airflow may be blown out from between the swirl blades of the swirl module 4. Among them, the air outlet speed of the air outlet when the swirl module 4 stops rotating is greater than the air outlet speed of the air outlet when the swirl module 4 rotates.

[0060] Specifically, in one embodiment of the air conditioner, the swirl module 4 includes a first wind wheel and a second wind wheel that are arranged opposite to each other, the first wind wheel includes a plurality of first rotating blades that are arranged at intervals along the circumference, and the second wind wheel includes a plurality of second rotating blades that are arranged at intervals along the circumference. Specifically, the first wind wheel is fixed to the ventilation hole, and the second wind wheel can rotate relative to the first wind wheel. Specifically, the first wind wheel can be provided with a limiting member that cooperates with the second wind wheel, and when the first wind wheel rotates, the second wind wheel can rotate with the first wind wheel under the limiting action of the limiting member. Wherein, during the synchronous rotation of the first wind wheel and the second wind wheel, the first wind wheel and the second wind wheel have a first relative position and a second relative position, the first relative position is a position where the first rotating blade and the second rotating blade are arranged in a counterposition, and the second relative position is a position where the first rotating blade and the second rotating blade are arranged in a staggered manner. The ventilation area of ​​the swirl module corresponding to the first relative position is greater than the ventilation area of ​​the swirl module corresponding to the second relative position, and the wind dispersion effect of the swirl module corresponding to the second relative position is better than the wind dispersion effect of the swirl module corresponding to the first relative position.

[0061] Further, in one embodiment of the air conditioner, referring to Figure 3 , the second air dispersion plate 32 may also be provided with a connecting rod and a louver 5 connected to the connecting rod on the side facing away from the first air dispersion plate 31, and the louver 5 includes a plurality of air guide blades connected by the connecting rod. Based on this, in the second air guiding state, the connecting rod can be moved in the up-down direction or the left-right direction to drive the louver 5 to swing back and forth or guide the air at a fixed angle to adjust the air outlet direction; in the first air guiding state, the louver 5 located in the air duct can be adjusted when it is set at different angles with the connecting rod, wherein, when the louver 5 is parallel to the airflow direction in the air duct, the air outlet volume of the air outlet is larger than when the louver 5 is in other positions. Specifically, each air guide blade may be set corresponding to a swirl module 4.

[0062] Furthermore, the air conditioner further comprises a first temperature sensor 6 and a second temperature sensor 8. The first temperature sensor 6 is specifically used to detect the indoor ambient temperature, and the second temperature sensor 8 is specifically used to detect the indoor heat exchanger temperature.

[0063] In this embodiment, the first temperature sensor 6 is disposed at the return air outlet of the air conditioner. In other embodiments, the first temperature sensor 6 may also be disposed on the outer wall of the housing 1 or in an indoor environment outside the air conditioner.

[0064] In this embodiment, the second temperature sensor 8 is disposed on the coil of the indoor heat exchanger 7, for example, in the middle of the coil. In other embodiments, the second temperature sensor 8 may also be disposed in the air duct near the indoor heat exchanger 7, for example, on the inner wall of the air duct on the air outlet side of the indoor heat exchanger 7.

[0065] The embodiment of the present invention further provides an air conditioning control device, which is used to control the above air conditioner. The control device can be built into the air conditioner or independently arranged outside the air conditioner according to actual needs.

[0066] In the embodiment of the present invention, refer to Figure 4 The air conditioning control device includes: a processor 1001 (such as a CPU), a memory 1002, and a timer 1003. The processor 1001, the memory 1002, and the timer 1003 can be connected via a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0067] Specifically, the indoor fan 2, the air guide assembly 3, the swirl module 4, the shutter 5, the first temperature sensor 6, the second temperature sensor 8, etc. in the air conditioner are all connected to the control device in this embodiment.

[0068] Those skilled in the art will understand that Figure 4 The device structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0069] like Figure 4 As shown, the memory 1002 as a computer-readable storage medium may include an air conditioning control program. Figure 4 In the device shown, the processor 1001 can be used to call the air conditioning control program stored in the memory 1002 and execute the relevant steps of the air conditioning control method in the following embodiments.

[0070] The embodiment of the present invention further provides an air conditioning control method, which is applied to control the above air conditioner.

[0071] Reference Figure 5 , an embodiment of the air conditioning control method of the present application is proposed. In this embodiment, the air conditioning control method includes:

[0072] Step S10, when the air conditioner is in a heating state, obtaining the temperature of the indoor heat exchanger;

[0073] Specifically, the data detected by the temperature sensor on the indoor heat exchanger coil can be read in real time or at set intervals after the air conditioner is started for heating, and the obtained data can be used as the indoor heat exchanger temperature here.

[0074] Step S20, when the temperature of the indoor heat exchanger is greater than or equal to the first temperature threshold, determining a target adjustment rate of the indoor fan according to the indoor ambient temperature; different indoor ambient temperatures correspond to different target adjustment rates;

[0075] The target adjustment rate specifically refers to the adjustment amount of the speed per unit time during the indoor fan speed adjustment process.

[0076] The first temperature threshold is specifically a critical temperature of the indoor heat exchanger that is pre-set for the purpose of preventing cold wind. When the indoor heat exchanger temperature is greater than or equal to the first temperature threshold, it indicates that if the fan is running at a speed greater than the set speed threshold, the air conditioner can blow out hot air, and the air outlet of the air conditioner will not make the user feel cold; when the indoor heat exchanger temperature is less than the first temperature threshold, it indicates that if the fan is running at a speed greater than the set speed threshold, the air conditioner will blow out cold air, and the air outlet of the air conditioner will make the user feel cold.

[0077] Different indoor ambient temperatures correspond to different target adjustment rates of the indoor fan. The correspondence between the indoor ambient temperature and the target adjustment rate can be preset, which can be a calculation relationship, a mapping relationship, or an algorithm model. Based on the preset correspondence, the target adjustment rate of the indoor fan corresponding to the current indoor ambient temperature can be determined.

[0078] Specifically, when a calculation formula characterizing the quantitative relationship between the indoor ambient temperature and the target adjustment rate is pre-set, the currently detected indoor ambient temperature can be substituted into the calculation formula, and the calculation result obtained is used as the target adjustment rate. In addition, a mapping table between the indoor ambient temperature and the target adjustment rate can also be pre-set, and the mapping table is queried by the indoor ambient temperature, and the matching result is used as the target adjustment rate.

[0079] Step S30, controlling the indoor fan to increase its speed according to the target adjustment rate.

[0080] The indoor fan continuously increases its current speed at the target adjustment rate. Specifically, the indoor fan speed increase may be stopped when the speed reaches the target speed, or may be stopped when the indoor heat exchanger temperature reaches a preset temperature, the preset temperature is greater than or equal to the first temperature threshold, and so on.

[0081] An air conditioning control method proposed in an embodiment of the present invention increases the speed of the indoor fan when the temperature of the indoor heat exchanger is greater than or equal to a first temperature threshold during the heating operation of the air conditioner, thereby preventing a large amount of cold air from being sent into the room when the coil temperature is insufficient. In the process of increasing the speed of the indoor fan, the increase rate is not pre-set, but changes to adapt to the change of the indoor ambient temperature. Based on this, it can be ensured that the increase rate of the indoor fan speed can be accurately matched with the current working conditions, and the increase rate will not be too large or too small, thereby ensuring that the hot air can be sent into the room in time and the heat exchange efficiency of the indoor heat exchanger can be matched with the actual heating efficiency of the air conditioner, thereby avoiding the cold wind from blowing on people while improving the heating effect of the air conditioner on the indoor environment.

[0082] Further, in the above embodiment, the target adjustment rate increases with the increase of the indoor ambient temperature. On the contrary, the target adjustment rate decreases with the decrease of the indoor ambient temperature. Based on this, when the indoor ambient temperature is high, the indoor heat exchange demand is relatively small. At this time, a faster target adjustment rate is used to increase the speed of the indoor fan. After the indoor air exchanges heat with the indoor heat exchanger, the temperature of the indoor heat exchanger will not drop too fast. At the same time, the air conditioner can send hot air into the indoor environment as soon as possible, so that the hot air can be quickly diffused in the indoor environment, thereby effectively improving the heat exchange effect of the air conditioner. In addition, when the indoor ambient temperature is low, the indoor heat exchange demand is relatively large. At this time, a slower target adjustment rate is used to increase the speed of the indoor fan. After the indoor air exchanges heat with the indoor heat exchanger, the temperature of the indoor heat exchanger will not drop too fast. The fan can adapt to the actual heating efficiency of the air conditioner and the actual heat exchange efficiency of the heat exchanger and run at a speed as high as possible, so that when the indoor coil temperature is high enough, a large amount of hot air can be continuously sent into the room, so that the indoor ambient temperature is quickly increased, and the heating effect is effectively improved.

[0083] Specifically, in this embodiment, the process of determining the target adjustment rate of the indoor fan according to the indoor ambient temperature in step S20 is as follows:

[0084] Step S21, when the indoor ambient temperature is within a first temperature range, determining a first rotation speed adjustment rate as the target adjustment rate;

[0085] Step S22, when the indoor ambient temperature is within the second temperature range, determining the second speed adjustment rate as the target adjustment rate;

[0086] Step S23, when the indoor ambient temperature is within a third temperature range, determining a third rotation speed adjustment rate as the target adjustment rate;

[0087] Among them, the temperature in the first temperature range is lower than the temperature in the second temperature range, the temperature in the second temperature range is lower than the temperature in the third temperature range, the first speed adjustment rate is lower than the second speed adjustment rate, and the second speed adjustment rate is lower than the third speed adjustment rate.

[0088] The first temperature interval, the second temperature interval and the third temperature interval are pre-divided temperature intervals, which may be continuous intervals or discontinuous intervals. The deviation between two critical values ​​of each temperature interval may be the same or different, and may be specifically set according to actual conditions.

[0089] The maximum critical temperature of the first temperature interval is lower than the minimum critical temperature of the second temperature interval, and the maximum critical temperature of the second temperature interval is lower than the minimum critical temperature of the third temperature interval.

[0090] The first speed adjustment rate, the second speed adjustment rate and the third speed adjustment rate are specifically preset rate values ​​for adjusting the speed of the indoor fan.

[0091] The correspondence between each temperature interval and its corresponding speed adjustment rate can be a pre-set fixed relationship; in addition, in order to further improve the accuracy of the determined target adjustment rate to ensure the effective improvement of the heat exchange effect, the correspondence between each temperature interval and its corresponding speed adjustment rate is obtained based on the current frequency of the compressor and / or the current opening of the electronic expansion valve in the refrigerant circulation loop where the indoor heat exchanger is located. It should be noted that when the indoor ambient temperature and the speed adjustment rate are other types of correspondence, they can also be obtained by the current frequency of the compressor and / or the current opening of the electronic expansion valve.

[0092] For example, when T1≤5℃, it may be the first temperature interval, and the target adjustment rate K is a lower increase rate, such as 8rps; when 5<T1≤15℃, it may be the second temperature interval, and the target adjustment rate K is a medium increase rate, such as 16rps; when 15℃<T1, it may be the third temperature interval, and the target adjustment rate K is a higher increase rate, such as 32rps.

[0093] In this embodiment, the corresponding speed adjustment rate is obtained based on the temperature range of the indoor ambient temperature as the target adjustment rate of the indoor fan, which is beneficial to avoid the influence of indoor ambient temperature fluctuations on the speed adjustment rate, and ensure that when the indoor ambient temperature fluctuates within a smaller range, the speed of the indoor fan can be steadily increased according to a relatively fixed speed adjustment rate, thereby improving the heat exchange effect of the air conditioner and ensuring the stability of the indoor fan operation.

[0094] It should be noted that in other embodiments, when determining the target adjustment rate based on the temperature interval in which the indoor ambient temperature is located, more or fewer temperature intervals than the temperature intervals in this embodiment may be divided according to actual needs, such as 2 temperature intervals, 4 temperature intervals, 6 temperature intervals, 8 temperature intervals, etc. Different temperature intervals correspond to different speed adjustment rates.

[0095] Further, based on the above embodiment, another embodiment of the air conditioning control method of the present application is proposed. In this embodiment, referring to Figure 6 The step of determining the target adjustment rate of the indoor fan according to the indoor ambient temperature is defined as step S20a. After step S10, the step further includes:

[0096] Step S101, determining whether the temperature of the indoor heat exchanger is greater than or equal to a first temperature threshold;

[0097] If yes, execute step S20a;

[0098] If not, execute step S102;

[0099] Step S102, determining whether the temperature of the indoor heat exchanger is greater than or equal to a second temperature threshold;

[0100] When the temperature of the indoor heat exchanger is lower than the first temperature threshold and greater than or equal to the second temperature threshold, step S103 is executed; when the temperature of the indoor heat exchanger is lower than the second temperature threshold, step S104 is executed.

[0101] Step S103, controlling the indoor fan to run at a first speed;

[0102] Step S104, controlling the indoor fan to stop.

[0103] Based on this, the step of controlling the indoor fan to increase the speed according to the target adjustment rate includes: step S31, controlling the indoor fan to increase the speed to a second speed according to the target adjustment rate;

[0104] The first rotation speed is smaller than the second rotation speed, and the first temperature threshold is larger than the second temperature threshold.

[0105] The first temperature threshold and the second temperature threshold may be pre-set parameters, or may be parameters obtained according to the actual operation of the air conditioner, or may be parameters set by the user. In this embodiment, different temperature change trends of the indoor heat exchanger correspond to different first temperature thresholds and second temperature thresholds, and / or different outdoor ambient temperatures correspond to different first temperature thresholds and second temperature thresholds.

[0106] Different temperature ranges of the indoor heat exchanger correspond to different speed values ​​of the indoor fan. When the temperature of the indoor heat exchanger is between the first temperature threshold and the second temperature threshold, the corresponding speed of the indoor fan is the first speed. When the temperature of the indoor heat exchanger is above the first temperature threshold, the corresponding speed of the indoor fan is the second speed. When the temperature of the indoor heat exchanger is less than the second temperature threshold, the indoor fan is shut down. When the temperature of the indoor heat exchanger is above the first temperature threshold, before determining the target adjustment rate of the indoor fan according to the indoor ambient temperature, it is possible to first identify whether the current speed of the indoor fan is greater than or equal to the second speed. When the current speed of the indoor fan is greater than or equal to the second speed, the indoor fan can be controlled to maintain the current speed or reduce the speed. When the current speed of the indoor fan is lower than the second speed, the step of determining the target adjustment rate of the indoor fan according to the indoor ambient temperature is executed.

[0107] When the temperature of the indoor heat exchanger is lower than the first temperature threshold and greater than or equal to the second temperature threshold, if the current speed of the indoor fan has not reached the first speed, when the speed needs to be increased, the speed increase rate can be a fixed rate, or the speed adjustment rate can be determined according to the indoor ambient temperature.

[0108] In this embodiment, when the temperature of the indoor heat exchanger is too low during the heating process, the indoor fan stops to avoid cold wind blowing towards the user; when the temperature of the heat exchanger is relatively high but the deviation from the room temperature is small, the indoor fan runs at a low speed, and the air conditioner sends a breeze into the room, ensuring heat exchange of the indoor air while avoiding a large amount of air with insufficient temperature blowing towards the user, thereby ensuring user comfort; and when the temperature is high enough, the indoor fan runs at a high speed, so that a large amount of hot air with sufficiently high temperature is sent into the room, thereby realizing rapid adjustment of the indoor ambient temperature and satisfying the user's thermal comfort.

[0109] There is no specific limitation on the order in which step S101 and step S102 are executed. They can be executed sequentially or simultaneously according to actual needs. It is only necessary to adjust the speed of the indoor fan based on the obtained judgment result.

[0110] It should be noted that the first temperature threshold and the second temperature threshold are both anti-cold wind control temperature thresholds. In other embodiments, the breeze interval can also be cancelled, that is, when the temperature of the indoor heat exchanger is less than the first temperature threshold, the indoor fan is controlled to stop. Alternatively, in other embodiments, more anti-cold wind control temperature thresholds including the first temperature threshold can be provided. Among the multiple anti-cold wind control thresholds, the first temperature threshold can be the threshold with the largest value, the threshold with the smallest value, or neither the largest nor the smallest threshold. Based on the multiple anti-cold wind control thresholds, the temperature of the indoor heat exchanger can be divided into multiple temperature intervals. Different temperature intervals correspond to different indoor fan speeds. The indoor fan speed tends to increase with the increase of the temperature of the temperature interval, and tends to decrease with the decrease of the temperature of the temperature interval. In this process, if the speed of the indoor fan needs to be increased, the speed increase rate of the indoor fan can be determined according to the indoor ambient temperature.

[0111] Further, in this embodiment, the process of determining the first temperature threshold and / or the second temperature threshold is as follows:

[0112] The first temperature threshold and / or the second temperature threshold are acquired according to a temperature change trend of the indoor heat exchanger and an outdoor ambient temperature.

[0113] Wherein, if the temperature change trend of the indoor heat exchanger is different and the outdoor ambient temperature is different, the first temperature threshold and / or the second temperature threshold. In this embodiment, the first temperature threshold and the second temperature threshold are determined according to the temperature change trend and the outdoor ambient temperature; in other embodiments, if the second temperature threshold is not set, the first temperature threshold can be determined separately according to the temperature change trend of the indoor heat exchanger and the outdoor ambient temperature; or, if multiple cold wind control temperature thresholds including the first temperature threshold are set, each cold wind control temperature threshold can be determined according to the temperature change trend and the outdoor ambient temperature.

[0114] The target temperature threshold is defined to include a first temperature threshold and / or a second temperature threshold. The correspondence between the temperature change trend, the outdoor ambient temperature and the target temperature threshold can be preset, and the correspondence can be in the form of a calculation formula, a mapping relationship, etc. Based on the correspondence, the target temperature threshold corresponding to the current outdoor ambient temperature and the temperature change trend can be determined. In the correspondence, the target temperature threshold may increase with the increase of the outdoor ambient temperature, and the target temperature threshold corresponding to the temperature change trend is an upward trend is greater than the target temperature threshold corresponding to the temperature change trend is a downward trend.

[0115] In this embodiment, the heating amount output by the air conditioner is different at different outdoor ambient temperatures, and the risk of the indoor heat exchanger sending cold air to the environment is different under different temperature change trends. Therefore, the first temperature threshold and / or the second temperature threshold for anti-cold wind control are determined in combination with the outdoor ambient temperature and the temperature change trend of the heat exchanger, thereby ensuring that the speed of the indoor fan can match the heating amount output by the air conditioner, ensuring that the speed of the indoor fan can ensure that cold wind is prevented from blowing people while improving the heating effect of the air conditioner on the indoor environment.

[0116] Specifically, in this embodiment, the step of obtaining the first temperature threshold and / or the second temperature threshold according to the temperature change trend of the indoor heat exchanger and the outdoor ambient temperature includes:

[0117] Step S01, obtaining a first set temperature threshold and / or a second set temperature threshold according to the temperature change trend, and determining a temperature correction value according to the outdoor ambient temperature;

[0118] The first set temperature threshold and the second set temperature threshold are preset temperature critical values ​​of the indoor heat exchanger corresponding to different indoor fan speeds, that is, the cold wind prevention control temperature thresholds of the air conditioner.

[0119] Different temperature change trends may correspond to different first set temperature thresholds and / or second set temperature thresholds. Specifically, the first set temperature threshold and / or the second set temperature threshold associated with an upward trend in the temperature change trend is greater than the first set temperature threshold and / or the second set temperature threshold associated with a downward trend in the temperature change trend. Based on the pre-set mapping relationship between the temperature change trend and the first set temperature threshold and / or the second set temperature threshold, the first set temperature threshold and / or the second set temperature threshold corresponding to the current change trend of the indoor heat exchanger can be determined. Based on this, the first temperature threshold and / or the second temperature threshold corresponding to an upward trend in the temperature change trend is greater than the first temperature threshold and / or the second temperature threshold corresponding to a downward trend in the temperature change trend.

[0120] Different outdoor ambient temperatures correspond to different temperature correction values. The greater the outdoor ambient temperature, the greater the temperature correction value may be, and the corresponding first temperature threshold and / or second temperature threshold may be greater. Specifically, the outdoor ambient temperature may be directly used as the temperature correction value; or the result of correcting the outdoor ambient temperature according to a preset rule may be used as the temperature correction value.

[0121] The correspondence between the outdoor ambient temperature and the temperature correction value may be pre-set with a calculation formula, a mapping table, etc., and the temperature correction value corresponding to the current outdoor ambient temperature may be determined based on the correspondence.

[0122] The temperature correction value includes a temperature correction amplitude or a temperature correction coefficient.

[0123] Step S02, correcting the first set temperature threshold according to the temperature correction value to obtain the first temperature threshold, and / or correcting the second set temperature threshold according to the temperature correction value to obtain the second temperature threshold; wherein the first set temperature threshold is greater than the second set temperature threshold.

[0124] Specifically, the sum, product or ratio of the first set temperature threshold and the temperature correction value may be used as the first set temperature threshold. In addition, the sum, product or ratio of the second set temperature threshold and the temperature correction value may be used as the second set temperature threshold.

[0125] In this embodiment, the temperature correction value is the temperature correction amplitude, and the sum of the first set temperature threshold and the temperature correction value can be used as the first temperature threshold, and the difference between the second set temperature threshold and the temperature correction value can be used as the second temperature threshold.

[0126] For example, when the temperature change trend of the indoor heat exchanger is an upward trend, the corresponding first set temperature threshold is Tm, then the first temperature threshold=T4+Tm, and T4 is the outdoor environment temperature.

[0127] In this embodiment, the pre-set temperature thresholds for anti-cold wind control (the first set temperature threshold and the second set temperature threshold) are obtained based on the temperature change trend of the indoor heat exchanger, and the obtained set temperature thresholds are corrected in combination with the indoor ambient temperature as the actual threshold for anti-cold wind control of the air conditioner, thereby ensuring the accuracy of the indoor fan's anti-cold wind control, ensuring that cold wind is prevented from blowing people while improving the air conditioner's indoor heat exchange effect.

[0128] Furthermore, in this embodiment, the step of determining the temperature correction value based on the outdoor ambient temperature includes: when the outdoor ambient temperature is greater than or equal to the preset ambient temperature, determining the preset ambient temperature as the temperature correction value; when the outdoor ambient temperature is less than the preset ambient temperature, determining the outdoor ambient temperature as the temperature correction value.

[0129] The specific value of the preset ambient temperature can be set according to actual needs. In this embodiment, the preset ambient temperature is a temperature value that is preset to be greater than 0°C and whose temperature deviation from 0°C is less than a set threshold, for example, 5°C.

[0130] Specifically, when the temperature change trend is an upward trend, the first set temperature threshold and the second set temperature threshold are defined as Tp1 and Tp2, and when the temperature change trend is a downward trend, the first set temperature threshold and the second set temperature threshold are defined as Tp3 and Tp4, Tp1>Tp2>Tp3>Tp4. Based on this, the first temperature threshold is defined as TE1 and TE2, the outdoor ambient temperature is defined as T4, and the preset ambient temperature is T0, then:

[0131] When the temperature change trend is an upward trend and T4 is greater than or equal to T0, TE1 = T0 + Tp1, TE2 = T0 + Tp2;

[0132] When the temperature change trend is a downward trend and T4 is greater than or equal to T0, TE1 = T0 + Tp3, TE2 = T0 + Tp4;

[0133] When the temperature change trend is an upward trend and T4 is less than T0, TE1 = T4 + Tp1, TE2 = T4 + Tp2;

[0134] When the temperature change trend is a downward trend and T4 is less than T0, TE1 = T4 + Tp3, TE2 = T4 + Tp4.

[0135] In this embodiment, since the heating efficiency of the air conditioner is low in a low temperature environment, the outdoor ambient temperature is used as the temperature correction value. As the outdoor ambient temperature decreases, the first temperature threshold and / or the second temperature threshold decreases accordingly, which is beneficial to increase the heating amount in a low temperature environment and improve the thermal comfort of indoor users.

[0136] Further, based on the above embodiment, another embodiment of the air conditioning control method of the present application is proposed. In this embodiment, the air conditioner includes a housing and an air guide component, the housing is provided with an air outlet, the air guide component is arranged on the housing and corresponds to the air outlet, the air guide component includes a first air dispersion plate and a second air dispersion plate, Figure 7 , while or before the step S103 is executed, it also includes:

[0137] When the temperature of the indoor heat exchanger is lower than the first temperature threshold and higher than the second temperature threshold, execute step S110: control the air guide assembly to operate in a target air guide state; wherein, in the target air guide state, the first air dispersion plate blocks the air outlet, and the second air dispersion plate blocks the airflow in the shell blowing toward the first air dispersion plate.

[0138] In this embodiment, when the temperature of the indoor heat exchanger is lower than the first temperature threshold and higher than the second temperature threshold, the temperature of the indoor heat exchanger is not yet high enough. When the air conditioner delivers air in a breeze, the air conditioner disperses the air through a double-layer air dispersion plate, thereby achieving a windless feeling and further preventing people from being blown by cold wind.

[0139] In addition, an embodiment of the present invention further proposes a computer-readable storage medium, on which an air conditioning control program is stored. When the air conditioning control program is executed by a processor, the relevant steps of any embodiment of the above air conditioning control method are implemented.
