Description

Technical Field

[0001] This application relates to the field of air conditioning equipment control technology, and in particular to an air conditioning control method, device, air conditioner, storage medium and computer program product. Background Technology

[0002] With economic development and improved living standards, people's demands for home appliances are constantly increasing. Simply diversifying functions is no longer sufficient to satisfy customers; it's necessary to simultaneously improve user comfort. When existing air conditioners are turned on in heating mode during winter, cold air is blown out during the initial heating phase because the indoor heat exchanger needs time to heat up. To avoid this, most air conditioners have an anti-cold-air function.

[0003] In traditional air conditioners, the anti-cold-wind function typically enters the anti-cold-wind program when the air conditioner is turned on for heating. Once the indoor heat exchanger temperature rises to the preset temperature, the anti-cold-wind program ends, and the indoor fan starts running at the speed corresponding to the set fan speed. However, in this mode, if the set fan speed is high, the indoor fan speed immediately becomes high, and the air volume increases rapidly. This causes the indoor heat exchanger temperature to drop quickly, resulting in a further decrease in the outlet air temperature. Consequently, after the anti-cold-wind program ends, the outlet air temperature actually decreases, resulting in the air not being hot or even reverting to blowing cold air. Summary of the Invention

[0004] Therefore, it is necessary to provide an air conditioning control method, device, air conditioner, computer-readable storage medium, and computer program product that can completely avoid the problem of air conditioning blowing cold air when the air conditioner is turned on for heating, in order to address the above-mentioned technical problems.

[0019] In one embodiment, controlling the indoor fan to increase its speed to a preset level based on the temperature zone of the indoor heat exchanger includes:

[0020] If the indoor ambient temperature falls within the medium temperature range, then when the indoor heat exchanger temperature is less than or equal to the fourth preset indoor heat exchanger temperature, the indoor fan is controlled to adjust to the set fan speed at the first medium temperature preset rate; when the indoor heat exchanger temperature is greater than the fourth preset indoor heat exchanger temperature but less than or equal to the fifth preset indoor heat exchanger temperature, the indoor fan is controlled to adjust to the set fan speed at the second medium temperature preset rate; when the indoor heat exchanger temperature is greater than the fifth preset indoor heat exchanger temperature, the indoor fan is controlled to run directly at the set fan speed.

[0021] If the indoor ambient temperature falls within a low-temperature zone, then when the indoor heat exchanger temperature is less than or equal to the fourth preset indoor heat exchanger temperature, the indoor fan is controlled to adjust to the set fan speed at a first low-temperature preset rate; when the indoor heat exchanger temperature is greater than the fourth preset indoor heat exchanger temperature and less than or equal to the fifth preset indoor heat exchanger temperature, the indoor fan is controlled to adjust to the set fan speed at a second low-temperature preset rate; when the indoor heat exchanger temperature is greater than the fifth preset indoor heat exchanger temperature, the indoor fan is controlled to adjust to the set fan speed at a third low-temperature preset rate.

[0023] First item,

[0024] If the temperature of the indoor heat exchanger is greater than or equal to the second preset indoor heat exchanger temperature and the operating time of the indoor fan is greater than or equal to the operating time threshold of the fan, then it is determined that the anti-cold air exit condition is met.

[0025] The second item,

[0026] If the indoor heat exchanger temperature is greater than or equal to the third preset indoor heat exchanger temperature, it is determined that the cold air exit condition is met; wherein, the first preset indoor heat exchanger temperature is less than the second preset indoor heat exchanger temperature, and the second preset indoor heat exchanger temperature is less than the third preset indoor heat exchanger temperature.

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] In one embodiment, the air conditioning control method provided in this application can be applied to, for example... Figure 1 The air conditioner shown. (Refer to...) Figure 1 The air conditioner includes a processor 1 and a compressor 2, a four-way valve 3, an indoor heat exchanger 4, and an indoor fan 5 connected to the processor 1. After the air conditioner enters the anti-cold air phase when heating is activated, the processor 1 monitors the air conditioner's operating parameters in real time. When the operating parameters determine that the conditions for starting the indoor fan are met, the processor 1 controls the indoor fan 5 to start and operate at a preset fan speed. When the indoor fan 5 operates at the preset fan speed until the conditions for exiting the anti-cold air phase are met according to the air conditioner's operating parameters, the processor 1 controls the indoor fan 5 to increase its speed to the set fan speed according to the preset rate corresponding to the air conditioner's operating parameters. The air conditioner's operating parameters can be obtained by monitoring the status of at least one of the compressor 2, the four-way valve 3, the indoor heat exchanger 4, and the indoor fan 5.

[0048] In one embodiment, such as Figure 2 As shown, this application provides an air conditioning control method, which is applied to... Figure 1 The following explanation uses the processor in the example, including steps 300 to 500. Wherein:

[0049] Step 300: After the air conditioner turns on heating and enters the anti-cold air stage, monitor the air conditioner's operating parameters in real time.

[0050] This can be achieved by the processor receiving a start command from the user via an input device, controlling the air conditioner's compressor and indoor heat exchanger to start operation, and switching the air conditioner's four-way valve to the energized state, thus putting the air conditioner into heating mode. Once the air conditioner is turned on and enters heating mode, it enters the anti-cold air stage. During this stage, the processor can control the indoor fan to start as needed and increase its speed to the set fan speed to ensure that the air conditioner's outlet temperature continuously meets the comfort range.

[0051] Specifically, during the cold air protection phase, the air conditioner's operating parameters need to be monitored in real time to determine whether the conditions for starting the indoor fan have been met. Furthermore, this monitoring is used to determine whether the conditions for exiting the cold air protection phase, such as increasing the indoor fan speed, have been met, and how to adjust the indoor fan speed to the user-inputted setting via an input device. Correspondingly, the air conditioner's operating parameters are not necessarily identical when determining whether the above different conditions are met. They can be operating parameters related to the indoor heat exchanger, compressor, four-way valve, or indoor fan, or any combination of these components' operating parameters.

[0052] Step 400: When the conditions for starting the indoor fan are met based on the air conditioner operating parameters, control the indoor fan to start and operate at the preset fan speed.

[0053] Specifically, the indoor fan start-up condition indicates that the indoor heat exchanger has been preheated for a period of time, and the anti-cold air phase has reached the point where the indoor fan can be turned on. Once the indoor fan start-up condition is met, the indoor fan can be controlled to start and operate at a preset fan speed. This preset fan speed can be the lowest fan speed corresponding to the indoor fan, or a speed lower than the lowest fan speed, to ensure that the start-up of the indoor fan does not significantly affect the outlet air temperature of the indoor heat exchanger, thus improving the reliability of the air conditioning's anti-cold air operation.

[0054] Before the indoor fan is turned on, the components of the air conditioner that are in operation include the indoor heat exchanger, compressor, and four-way valve. Correspondingly, the air conditioner operating parameters used to determine whether the indoor fan start-up conditions are met can include at least one or more of the following: operating parameters related to the indoor heat exchanger, operating parameters related to the compressor, and operating parameters related to the four-way valve. Specifically, operating parameters related to the indoor heat exchanger can include the surface temperature and operating time of the indoor heat exchanger; operating parameters related to the compressor can include the compressor's operating power and operating time; and operating parameters related to the four-way valve can include the time the four-way valve is engaged.

[0055] Furthermore, determining whether the conditions for starting the indoor fan are met can be done by checking whether the surface temperature of the indoor heat exchanger reaches a preset temperature threshold, or by checking whether the compressor running time or the four-way valve operation time reaches the corresponding preset running time threshold.

[0056] Step 500: When the indoor fan is controlled to run at the preset fan speed until the anti-cold air exit condition is met according to the air conditioning operating parameters, the indoor fan is controlled to increase to the set fan speed according to the preset speed corresponding to the air conditioning operating parameters.

[0057] Specifically, the "cold air prevention exit condition" indicates that the indoor heat exchanger has been preheated and can exit the cold air prevention stage. The indoor fan speed is then gradually increased to the set speed, entering the normal operation stage. The set speed is obtained by the user through an input device and can be understood as the user's desired airflow speed and volume from the indoor fan.

[0058] It is understandable that during the cold air prevention phase when the indoor fan operates at a preset fan speed, the main operating components affecting the outlet air temperature include the indoor heat exchanger and the indoor fan. Correspondingly, the air conditioning operating parameters used to determine whether the cold air prevention exit conditions are met can include relevant operating parameters of the indoor heat exchanger and relevant operating parameters of the indoor fan. Among these, the indoor fan-related operating parameters can include the indoor fan start-up time and the duration of operation at the preset fan speed. That is, determining whether the cold air prevention exit conditions are met can be based on whether the surface temperature of the indoor heat exchanger reaches another higher preset temperature threshold, or whether the indoor fan start-up time or the duration of operation at the preset fan speed reaches the corresponding preset operating time threshold.

[0059] Furthermore, after determining that the anti-cold air exit condition is met and exiting the anti-cold air stage, to avoid the problem of a drop in outlet air temperature caused by directly operating at a higher set fan speed, the processor can control the indoor fan to gradually increase from the preset fan speed to the set fan speed at a preset rate. The preset rate is not unique and can be determined based on the air conditioning operating parameters corresponding to the moment the anti-cold air stage exits. Since the indoor heat exchanger is the component that most directly affects the outlet air temperature, in this embodiment, the surface temperature of the indoor heat exchanger is used as the air conditioning operating parameter for determining the preset rate.

[0060] It is understandable that when determining the preset rate using the surface temperature of the indoor heat exchanger, the correspondence between the surface temperature of the indoor heat exchanger and the rate of increase at the exit of the anti-cold air phase can be obtained in advance based on experimental data and stored in the memory of the air conditioner unit. When the preset rate needs to be determined, the corresponding preset rate can be found in the correspondence based on the real-time collected surface temperature of the indoor heat exchanger. Furthermore, specifically, the preset rate can be determined based on the real-time collected surface temperature value of the indoor heat exchanger, or it can be determined based on the temperature zone to which the real-time collected surface temperature of the indoor heat exchanger belongs; it is not limited to this and can be determined according to the actual design method of the correspondence.

[0061] Furthermore, after determining that the anti-cold air exit conditions are met and exiting the anti-cold air stage, if the current indoor ambient temperature is high or the current indoor heat exchanger has been preheated to a high temperature, the outlet air temperature will not be affected by the indoor fan's operating speed. Alternatively, the processor can control the indoor fan to directly increase from the preset fan speed to the set fan speed without setting a preset speed, so as to ensure sufficient air volume output to improve the normal heating rate of the room.

[0062] The above-mentioned air conditioning control method monitors the air conditioning operating parameters in real time after the air conditioner is turned on for heating and enters the anti-cold air stage. When it is determined that the conditions for starting the indoor fan are met, the indoor fan is started to preheat. Then, when the conditions for exiting the anti-cold air stage are met, the indoor fan is controlled to gradually increase to the set fan speed according to the current air conditioning operating parameters. This avoids the problem of the air outlet temperature dropping directly after exiting the anti-cold air stage by running at a higher set fan speed, thus improving the user experience in the air conditioning heating mode.

[0063] In one embodiment, the air conditioning operating parameters include the indoor heat exchanger temperature T. 内管 It's understandable that the indoor heat exchanger temperature T... 内管 This refers to the surface temperature of the indoor heat exchanger. When the air conditioner is in heating mode, the surface temperature of the indoor heat exchanger will gradually increase. Step 400, which determines whether the indoor fan start-up conditions are met based on the air conditioner's operating parameters, includes: if the indoor heat exchanger temperature T... 内管 Greater than or equal to the first preset indoor heat exchanger temperature T 预设内管1 If the indoor fan starts, then the conditions for starting are met. The first preset indoor heat exchanger temperature T... 预设内管1 The value of T is not unique and can be determined based on the operating performance of the indoor heat exchanger of the air conditioner. For example, the range can be 30℃ to 50℃. This can be understood as T... 预设内管1 Set to a lower preset temperature, when the indoor heat exchanger is preheated to that lower T 预设内管1 When the air conditioner is running at its lowest setting, the internal fan can be activated. This ensures the normal heating rate of the air conditioner and prevents the outlet temperature from dropping due to excessive airflow.

[0064] In another embodiment, the air conditioner operating parameters include compressor running time t 压缩机运行时间 With the four-way valve in operation for t 四通阀投入运行时间 Then, step 400 determines whether the indoor fan start-up conditions are met based on the air conditioner operating parameters, including: if the compressor running time t 压缩机运行时间 The operating time t is greater than or equal to the compressor operating time threshold and the four-way valve is engaged for an operating time of t. 四通阀投入运行时间 If the operating time threshold of the four-way valve is greater than or equal to the threshold value, then the internal fan startup condition is considered met. This can be understood as using the compressor operating time t... 压缩机运行时间 With the four-way valve in operation for t 四通阀投入运行时间 Determining the start-up conditions of the indoor fan is to avoid excessively long preheating times for the indoor heat exchanger, which would result in a slow rate of temperature rise during normal heating. If the compressor running time t... 压缩机运行时间 With the four-way valve in operation for t 四通阀投入运行时间 After reaching the corresponding operating time threshold, the indoor heat exchanger temperature T 内管 The first preset indoor heat exchanger temperature T has not yet been reached.预设内管1 If the conditions for starting the internal fan are met, the internal fan can be directly determined and controlled to start running at the preset fan speed.

[0065] The values ​​for the compressor operating time threshold and the four-way valve activation operating time threshold are not unique and can be determined based on the starting and operating mechanisms of the compressor and the four-way valve. However, generally speaking, their start-up times in air conditioning heating mode are similar, so the compressor operating time threshold and the four-way valve activation operating time threshold can be set to the same operating time threshold t. 运行预设 The value can be set from 10s to 300s.

[0066] In one embodiment, the air conditioning operating parameters that can be used to determine the cold air protection shutdown condition include the indoor heat exchanger temperature T. 内管 , Internal fan operation time t 风机投入运行时间 and preset windshield running time t 最低风档运行时间 Specifically, after the hot airflow passes through the indoor heat exchanger for heat exchange, it is blown out from the air outlet. Therefore, the indoor heat exchanger temperature T can be used as the indicator. 内管 This is used to measure the outlet air temperature and determine whether the anti-cold air phase can be discontinued. Additionally, the operating time t of the indoor fan is also measured. 风机投入运行时间 and preset windshield running time t 最低风档运行时间 It can indicate whether the internal fan has reached stable operation, and therefore can also be used to determine whether the conditions for preventing cold air from being withdrawn are met.

[0067] In one embodiment, step 500, determining whether the anti-cold air exit condition is met based on the air conditioner operating parameters, includes: if the indoor heat exchanger temperature T... 内管 Greater than or equal to the second preset indoor heat exchanger temperature T 预设内管2 And the internal fan's operating time t 风机投入运行时间 Greater than or equal to the wind turbine's operating time threshold t 风机投入预设 If the condition for cooling fan shutdown is met, then the fan operation time threshold t is considered to be met. 风机投入预设 This value is not unique and can be determined based on the actual operating performance of the indoor fan. For example, the value range can be 0s to 300s. This embodiment indicates that the indoor heat exchanger has been preset to a slightly higher temperature and the indoor fan is already running stably, at which point the anti-cold air phase can be exited.

[0068] In one embodiment, step 500, determining whether the anti-cold air exit condition is met based on the air conditioner operating parameters, includes: if the indoor heat exchanger temperature T... 内管 Greater than or equal to the third preset indoor heat exchanger temperature T 预设内管3 If the cold air exit condition is met, then it is determined that the cold air exit condition is satisfied. This can be understood as the first preset indoor heat exchanger temperature T... 预设内管1 The second preset indoor heat exchanger temperature T 预设内管2 With the third preset indoor heat exchanger temperature T 预设内管3These are the temperature thresholds for each temperature increase, representing different preheating stages of the indoor heat exchanger. The three thresholds can range from 30℃ to 50℃, for example, T... 预设内管1 =35℃, T 预设内管2 =42℃, T 预设内管3 =49℃. This embodiment indicates that the indoor heat exchanger has been preset to a relatively high temperature and can directly exit the anti-cold air stage.

[0069] In one embodiment, step 500, determining whether the anti-cold air exit condition is met based on the air conditioner operating parameters, includes: if the preset fan speed operating time t 最低风档运行时间 Greater than or equal to the windshield operating time threshold t 风档运行预设 If the condition for stopping the cold air is met, then it is determined that the cold air dissipation condition is satisfied. The threshold for the fan speed control operation time is t. 风档运行预设 This value is not unique and can be determined based on the actual operating performance of the internal fan. For example, the range could be 0s to 600s. This embodiment indicates that the internal fan has been running at the preset fan speed for a sufficient period of time and can directly exit the anti-cold air stage.

[0070] In one embodiment, such as Figure 3 As shown, before step 400, the method also includes steps 100 and 200. It can be understood that steps 100 and 200 can be completed after step 300, before step 300, or simultaneously. Wherein:

[0071] Step 100: Obtain the indoor ambient temperature and determine the temperature zone to which the indoor ambient temperature belongs.

[0072] Among them, indoor ambient temperature T 内环 This refers to the temperature of the environment in which the indoor unit of the air conditioner is located. It can be understood that when the indoor ambient temperature T... 内环 The temperature change required for an air conditioner to enter heating mode and reach the set temperature varies depending on the ambient temperature T. 内环 The higher the temperature, the less sensitive users are to the low outlet air temperature during the air conditioner's anti-cold air phase. Correspondingly, the preheating time of the indoor heat exchanger is shorter, and the rate at which the indoor fan accelerates from the preset setting to the set setting can be increased, or even directly adjusted to operate at the set fan speed, to maintain the indoor ambient temperature T. 内环 It reaches the set temperature more quickly. Therefore, it can be used in different indoor ambient temperatures. 内环 Adjust the corresponding judgment thresholds for the start-up conditions of the indoor fan and the exit conditions for the cold air prevention to improve the normal heating rate of the room.

[0073] Specifically, indoor ambient temperature T 内环 It can then be used directly for subsequent threshold determination, or it can be used to determine the current indoor ambient temperature T after dividing the temperature range. 内环 The temperature zone to which it belongs, and then based on the indoor ambient temperature T内环 The corresponding threshold is determined based on the temperature zone. Furthermore, when using indoor ambient temperature T... 内环 When determining the threshold for a given temperature zone, the number of temperature intervals is not unique; it can be set to two, three, or more temperature intervals depending on actual needs.

[0074] For example, in this embodiment, a first indoor ambient temperature threshold T can be set. 预设内环1 With the second indoor ambient temperature threshold T 预设内环2 The indoor ambient temperature is divided into three temperature zones. The first indoor ambient temperature threshold T... 预设内环1 Greater than the second indoor ambient temperature threshold T 预设内环2 Its value range can be 0℃ to 25℃. For example, the first indoor ambient temperature threshold T 预设内环1 The second indoor ambient temperature threshold T is 20℃. 预设内环2 The temperature is 10℃. Therefore, when the indoor ambient temperature T... 内环 Greater than or equal to the first indoor ambient temperature threshold T 预设内环1 When the temperature is T, the temperature zone is considered a high-temperature zone; when the indoor ambient temperature is T... 内环 Less than the first indoor ambient temperature threshold T 预设内环1 And greater than or equal to the second indoor ambient temperature threshold T 预设内环2 At that time, the temperature zone is the medium temperature zone; when the indoor ambient temperature T 内环 Less than the second indoor ambient temperature threshold T 预设内环2 At that time, the temperature range it belongs to is the low temperature range.

[0075] Step 200: Determine the compressor operating time threshold and the four-way valve activation operating time threshold based on the temperature zone of the indoor ambient temperature.

[0076] It is understandable that when the indoor ambient temperature T 内环 The higher the threshold, the shorter the preheating time of the indoor heat exchanger. Therefore, the compressor operating time threshold and the four-way valve activation operating time threshold can be used, i.e., the same operating time threshold t. 运行预设 It can be set to a shorter threshold.

[0077] Specifically, the runtime threshold t 运行预设 The number can be determined based on the number of temperature ranges divided by the indoor ambient temperature. Using the first indoor ambient temperature threshold T as described above... 预设内环1 With the second indoor ambient temperature threshold T 预设内环2 Taking the division of indoor ambient temperature into three temperature zones as an example, for t 运行预设 The settings will be explained. When the indoor ambient temperature T 内环 When the temperature zone is a high-temperature zone, the required preheating time for the indoor heat exchanger is the shortest, therefore the first operating time threshold t is... 运行预设1 Shortest; when the indoor ambient temperature T内环 When the temperature range is medium, the corresponding second running time threshold t 运行预设2 A little longer; when the indoor ambient temperature T 内环 When the temperature range is low, the corresponding third running time threshold t 运行预设3 The longest. For example, the first runtime threshold t can be used. 运行预设1 Set to 40s, second runtime threshold t 运行预设2 Set to 120s, third runtime threshold t 运行预设3 Set it to 180s.

[0078] Furthermore, when the indoor ambient temperature T 内环 When the temperature zone is a high-temperature zone, step 400 determines whether the indoor fan start-up conditions are met based on the air conditioning operating parameters, including: if the compressor running time t 压缩机运行时间 With the four-way valve in operation for t 四通阀投入运行时间 All are greater than or equal to the first running time threshold t 运行预设1 If the indoor ambient temperature T is within a certain range, then the conditions for starting the indoor fan are met. 内环 When the temperature zone is medium, step 400 determines whether the indoor fan start-up conditions are met based on the air conditioning operating parameters, including: if the compressor running time t 压缩机运行时间 With the four-way valve in operation for t 四通阀投入运行时间 All are greater than or equal to the second running time threshold t 运行预设2 If the indoor ambient temperature T is within a certain range, then the conditions for starting the indoor fan are met. 内环 When the temperature zone is a low temperature zone, step 400 determines whether the indoor fan start-up conditions are met based on the air conditioning operating parameters, including: if the compressor running time t 压缩机运行时间 With the four-way valve in operation for t 四通阀投入运行时间 All are greater than or equal to the third running time threshold t 运行预设3 If the condition is met, then the internal fan start-up conditions are satisfied.

[0079] In one embodiment, the air conditioning operating parameters include the indoor heat exchanger temperature T. 内管 Then, in step 500, the indoor fan is controlled to increase to the set fan speed according to the preset speed corresponding to the air conditioning operating parameters, including: controlling the indoor fan to increase to the set fan speed according to the preset speed corresponding to the temperature zone to which the indoor heat exchanger temperature belongs.

[0080] It is understandable that indoor heat exchangers generally heat up slowly. Therefore, after exiting the anti-cold-wind stage, this application gradually increases the indoor fan speed from the preset setting to the set setting to avoid a significant drop in outlet air temperature due to increased airflow, resulting in cold air blowing in. However, to ensure a normal heating rate, if the indoor heat exchanger temperature T... 内管Since the air has already been preheated to a relatively high temperature, the outlet air temperature will not be significantly affected by the operating speed of the indoor fan. Therefore, the preset speed can be increased appropriately, or even no preset speed can be set. The processor can control the indoor fan to directly increase the speed from the preset speed to the set speed to ensure sufficient airflow to improve the normal heating rate of the room.

[0081] Specifically, when using an indoor heat exchanger at temperature T 内管 When determining the preset rate for the temperature zones, the number of preset rates corresponding to the divided temperature zones is not fixed; it can be two, three, or more than three. In this embodiment, a fourth preset indoor heat exchanger temperature T is used. 预设内管4 With the fifth preset indoor heat exchanger temperature T 预设内管5 The indoor heat exchanger temperature T 内管 The explanation will be based on dividing the temperature into three zones. The fourth preset indoor heat exchanger temperature T... 预设内管4 Less than the fifth preset indoor heat exchanger temperature T 预设内管5 Its value range can be 30℃ to 50℃. For example, the fourth preset indoor heat exchanger temperature T 预设内管4 The fifth preset indoor heat exchanger temperature is 36℃. 预设内管5 The temperature is 46℃. Therefore, when the indoor heat exchanger temperature T... 内管 Less than or equal to the fourth preset indoor heat exchanger temperature T 预设内管4 When the temperature is T, the temperature zone is the first temperature zone; when the indoor heat exchanger temperature is T... 内管 Greater than the fourth preset indoor heat exchanger temperature T 预设内管4 And less than or equal to the fifth preset indoor heat exchanger temperature T 预设内管5 When the temperature is T, the temperature zone is the second temperature zone; when the indoor heat exchanger temperature is T 内管 Greater than the fifth preset indoor heat exchanger temperature T 预设内管5 At that time, the temperature zone it belongs to is the third temperature zone.

[0082] Furthermore, when the indoor heat exchanger temperature T 内管 When the temperature zone is the first temperature zone, the indoor fan is controlled to adjust to the set fan speed at the first preset speed; when the indoor heat exchanger temperature T 内管 When the temperature zone is the second temperature zone, the indoor fan is controlled to adjust to the set fan speed at the second preset speed; when the indoor heat exchanger temperature T 内管 When the temperature zone is the third temperature zone, the internal fan is adjusted to the set speed at the third preset speed. The first preset speed is less than the second preset speed, and the second preset speed is less than the third preset speed. The value range is 5 rpm / 10s to 1000 rpm / 10s.

[0083] It is understandable that when the indoor ambient temperature T 内环The higher the fan speed, the less sensitive users are to the low air outlet temperature during the air conditioner's anti-cold air phase. This allows for a higher rate at which the indoor fan accelerates from the preset speed to the set speed, or even direct operation at the set fan speed to maintain the indoor ambient temperature T. 内环 To reach the set temperature more quickly. For example, if the indoor ambient temperature T 内环 The temperature zone is high, indicating that the current ambient temperature is already high. Therefore, after the anti-cold draft phase ends, the indoor fan can be directly adjusted from the preset fan speed to the set speed. If the indoor ambient temperature T... 内环 The temperature zone it belongs to is the medium temperature zone, but the indoor heat exchanger temperature T 内管 The temperature zone is the third temperature zone, which has been preheated to a higher temperature. After the anti-cold air stage is over, the indoor fan can be directly adjusted from the preset fan speed to the set fan speed.

[0084] In one embodiment, if the indoor ambient temperature T 内环 The temperature zone is medium temperature zone and the indoor heat exchanger temperature T 内管 When the temperature zone is the first temperature zone, the indoor fan is controlled to increase to the set fan speed according to the preset rate corresponding to the temperature zone of the indoor heat exchanger, including: controlling the indoor fan to adjust to the set fan speed at the first medium temperature preset rate α.

[0085] In one embodiment, if the indoor ambient temperature T 内环 The temperature zone is medium temperature zone and the indoor heat exchanger temperature T 内管 When the temperature zone is the second temperature zone, the indoor fan is controlled to increase to the set fan speed according to the preset rate corresponding to the temperature zone of the indoor heat exchanger, including: controlling the indoor fan to adjust to the set fan speed at the second medium temperature preset rate β.

[0086] In one embodiment, if the indoor ambient temperature T 内环 The temperature zone it belongs to is the low temperature zone and the indoor heat exchanger temperature T 内管 When the temperature zone is the first temperature zone, the indoor fan is controlled to increase to the set fan speed according to the preset speed corresponding to the temperature zone of the indoor heat exchanger, including: controlling the indoor fan to adjust to the set fan speed at the first low temperature preset speed γ.

[0087] In one embodiment, if the indoor ambient temperature T 内环 The temperature zone it belongs to is the low temperature zone and the indoor heat exchanger temperature T 内管 When the temperature zone is the second temperature zone, the indoor fan is controlled to increase to the set fan speed according to the preset rate corresponding to the temperature zone of the indoor heat exchanger, including: the indoor fan is controlled to adjust to the set fan speed at the second low temperature preset rate δ.

[0088] In one embodiment, if the indoor ambient temperature T 内环The temperature zone it belongs to is the low temperature zone and the indoor heat exchanger temperature T 内管 When the temperature zone is the third temperature zone, the indoor fan is controlled to increase to the set fan speed according to the preset rate corresponding to the temperature zone of the indoor heat exchanger, including: the indoor fan is controlled to adjust to the set fan speed at the third low temperature preset rate λ.

[0089] It is understandable that, based on the temperature range setting, the first low temperature preset rate γ, the second low temperature preset rate δ, the third low temperature preset rate λ, the first medium temperature preset rate α, and the second medium temperature preset rate β are rate thresholds that increase sequentially. The specific values ​​are not limited and can be set according to the actual operating conditions.

[0105] In one embodiment, such as Figure 6 As shown, an indoor ambient temperature T is provided. 内环 The temperature range it belongs to is the low temperature range (i.e., T). 内环 <T 预设内环2 When this occurs, the corresponding air conditioning control method includes steps 310-370:

[0113] The following explanation uses a 3-horsepower floor-standing room air conditioner as an example, where the parameter value is: T 预设内环1 =20℃, T 预设内环2 =10℃, t 运行预设1 =40s,t 运行预设2 =120s,t 运行预设3 =180s, T 内管预设1 =35℃, T 内管预设2 =42℃, T 内管预设3 =49℃, t 风机投入预设 =30s,t 风档运行预设 =300s, γ=5rpm / 10s, δ=10rpm / 10s, λ=20rpm / 10s, α=30rpm / 10s, β=50rpm / 10s, T 内管预设4 =36℃, T 内管预设5 =46℃. All the parameters above and the value ranges in the above embodiments were obtained through experimental testing and are not intended to limit the embodiments of this application. Any parameter value that satisfies the air conditioning control method of this application should be within the protection scope of this application.

[0114] Experimental test room and temperature sensor layout as follows Figure 7 As shown, assume the room area is 47.16m². 2 (Length 6.8m, Width 5.2m, Height 2.8m), the walls and floor are made of insulated panels, and the air conditioner is placed as shown in the figure. Furthermore, to test the control effect of the air conditioning control method of this application on the outlet air temperature and indoor ambient temperature, 294 temperature sensors were installed in the room, and 3 temperature sensor test points were installed at the air conditioner outlet. Among them, as shown... Figure 7The room temperature sensor layout is as follows: Vertical direction: The first measuring point is 0.1m above the ground, simulating the height of a human ankle. A measuring point is placed every 0.3m, for a total of 7 measuring points, covering more than 90% of the human activity area. Horizontal width direction: No temperature measuring points are placed in non-residential areas away from the walls. Measuring points are placed starting 0.5m from the wall, spaced 0.7m apart, forming 7 rows of measuring points (1-7). Horizontal length direction: No temperature measuring points are placed in non-residential areas away from the walls. Measuring points are placed starting 1m from the wall, with 6 rows of temperature sensors (A-F) spaced 0.7m, 0.7m, 2m, 0.7m, and 0.7m apart, for a total of 294 temperature sensors.

[0115] Test Method: The indoor and outdoor operating units and the indoor test air conditioner were controlled using rated voltage. The indoor and outdoor operating units were used to maintain the following environmental parameters: indoor temperature 0℃, outdoor temperature -5℃, and outdoor humidity 60%. After the operating conditions stabilized, the indoor test air conditioner was set to heating mode, and the indoor fan was set to the highest fan speed (ultra-strong setting). The set temperature was 30℃, and the air guide vanes and air sweeping blades were adjusted to their default settings. The auxiliary electric heating was turned off, and the heating test began. The indoor operating unit was turned off simultaneously with the indoor test air conditioner. Data collection began when the air conditioner was turned on and continued for 20 minutes to conclude the test. The temperature sensor recorded one set of data every minute.

[0116] Using the same testing method, experiments were conducted on the conventional anti-cold air control scheme (which controls the internal fan to directly enter the set high-power mode after the anti-cold air operation ends) and the anti-cold air control method of this application, respectively. The data recorded by the temperature sensor were organized and plotted as follows. Figure 8 The graphs shown are illustrated below. As shown, the solid and dashed square lines represent the average indoor temperature curves obtained from the tests of the two different schemes; the solid and dashed round lines represent the average outlet air temperature curves obtained from the tests of the two different schemes. The test results show that when the air conditioning control method provided in this application is used, the outlet air temperature is higher than that of the conventional scheme, and the outlet air temperature is consistently above 40℃, with no feeling of cold air blowing. At the same time, the heating effect on the indoor temperature rise is comparable to the conventional scheme, balancing the comfort of the outlet air temperature with the rate of indoor temperature rise.
