[0017] In one embodiment, the step of controlling the operation of the air conditioning device based on the comparison result includes:

[0018] When the adjustment intensity of the control gear is less than the adjustment intensity of the operating gear, after controlling the air conditioning device to maintain the operating gear for a preset time, the air conditioning device is controlled to operate at the control gear.

[0019] In one embodiment, the step of controlling the operation of the air conditioning device based on the comparison result includes:

[0020] When the adjustment intensity of the control setting is less than that of the operating setting, the air conditioning device is controlled to maintain the operating setting. After the air quality reaches the target buffer opening threshold of the operating setting, the air conditioning device is controlled to operate at the control setting.

[0043] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] Air conditioning equipment is an important tool for improving air quality. Air conditioning equipment is typically equipped with multiple settings to meet the needs of different environments. However, when air quality changes within the critical range of adjacent settings, it is easy to repeatedly switch between adjacent settings, leading to unstable operation of the air conditioning equipment. Therefore, this application periodically detects the air quality of the air conditioning equipment, compares the control setting of the current cycle with the operating setting of the previous cycle, and controls the operation of the air conditioning equipment based on the comparison result, thereby avoiding the air conditioning equipment from switching back and forth between adjacent settings.

[0045] To overcome the above-mentioned deficiencies, this application provides a control method for air conditioning equipment:

[0046] Based on this, this application proposes a control method for an air conditioning device according to a first embodiment. Referring to Figure 1, the control method for the air conditioning device includes steps S10 to S30:

[0047] Step S10: Detect the air quality of the air conditioning device in the current cycle and obtain the control level corresponding to the air quality in the current cycle;

[0048] It should be noted that air conditioning equipment can be used for air conditioning, and can be used to regulate temperature, humidity, carbon dioxide concentration, formaldehyde, PM2.5 (particulate matter 2.5), and TOVC (total volatile organic compounds), etc. This embodiment does not specifically limit this. Air quality refers to the air quality of the environment when the air conditioning equipment is started. Air quality can be temperature, humidity, carbon dioxide concentration, formaldehyde concentration, PM2.5 concentration, or TOVC concentration, etc., and this embodiment does not specifically limit this.

[0049] Air conditioning equipment can be air conditioners, air purification equipment, fresh air systems, dehumidifiers, or humidifiers, etc. This embodiment does not specifically limit the air conditioning equipment. Air quality can be obtained through sensor detection.

[0050] Air conditioning equipment can include multiple control levels, each corresponding to a different intensity of air conditioning.

[0051] For example, the air conditioning equipment can detect air quality according to a preset cycle. The preset cycle can be determined based on actual conditions, such as 1 minute, 2 minutes, etc., and this embodiment does not specifically limit it. The air quality for the current cycle can be the latest air quality detected by the air conditioning equipment, and the control level for the air quality of the current cycle can be obtained.

[0052] Referring to Figure 6, in one embodiment, step S10 further includes steps S11 to S12:

[0053] Step S11: Obtain the mapping relationship between air quality and control gear.

[0054] Step S12: Based on the mapping relationship between air quality and control gear, find the control gear corresponding to the air quality of the current cycle.

[0055] It should be noted that each control setting in an air conditioning system has its own corresponding range, which includes the air quality corresponding to that control setting. The mapping relationship includes the relationship between the air quality corresponding to each control setting of the air conditioning system. For example, the control settings in an air conditioning system can be from 0 to 4. The air conditioning system can include settings from 0 to 4, and the corresponding ranges for each setting are (0, 800], (800, 1000], (1000, 1250], (1250, 1500], and (1500, N], where N is a value greater than 1500. When the detected air quality for the current cycle is 1100, then the control setting for the air quality for the current cycle is setting 3.

[0056] In one embodiment, the control level corresponding to the air quality of the current cycle is obtained through a mapping relationship, which facilitates subsequent comparison between the control level and the operating level of the current cycle in order to control the operation of the air conditioning equipment.

[0057] By concatenating the ranges of each control setting within the same mapping relationship, a control range can be obtained. In other embodiments, the control range of the same air conditioning device can be based on changes in air quality when the air conditioning device is started. The control range of the same air conditioning device will not change during the same operation, but the control range corresponding to the same air conditioning device may be different in different operation processes. For example, the control range corresponding to the air quality at the start of the air conditioning device can be obtained. Specifically, it can be based on the target relative ranking of the air quality at the start of the air conditioning device in a preset quality ranking; the control range corresponding to the target relative ranking is obtained as the control range of the air conditioning device.

[0058] The preset air quality ranking sequence includes multiple historical air quality sequences of the same type as the air quality, ordered according to their quality level. The target relative ranking represents the percentile of the air quality within the preset air quality ranking sequence. The target relative ranking describes the relative degree of air quality within the preset air quality ranking sequence. Different target relative rankings may correspond to different control intervals. Because the target relative ranking describes the relative degree of air quality, a corresponding control interval can be determined based on the target relative ranking, ensuring that the control interval matches the relative degree of air quality. This facilitates more effective air conditioning adjustments based on the control interval, improving the air quality control effect.

[0059] The steps for determining a preset air quality ranking sequence may include: acquiring historical operating data of other air conditioning devices in the same area as the air conditioning device; determining the historical air quality of each air conditioning device from the historical operating data; sorting the historical air quality to obtain a historical quality sequence; and determining the percentile ranking of each historical air quality within the historical quality sequence to obtain the preset air quality ranking sequence. For example, the historical air quality values ​​can be sorted from largest to smallest or smallest to largest to obtain the historical quality sequence. Normalizing the historical quality sequence can yield the preset air quality ranking sequence; this can be achieved by determining the percentile ranking of each historical air quality within the historical quality sequence to normalize the historical quality sequence. The percentile ranking can be used to describe the relative position of historical air quality within the historical quality sequence.

[0060] Historical operating data includes user adjustment data. Multiple user adjustment data can exist for the same air conditioning device. When the air conditioning is set to on / off adjustment type, the user adjustment data can include on / off quality thresholds. When the air conditioning is set to gear adjustment type, the user adjustment data can also include the gear adjustment thresholds of the air conditioning device. Historical air quality can be on / off quality thresholds, or it can be the weighted average of the average values ​​of the gear adjustment thresholds, etc.

[0061] The steps for obtaining the control interval corresponding to the target relative ranking include: determining the interval strategy to which the target relative ranking belongs in each preset ranking distribution interval of the preset distribution control mapping relationship; obtaining a preset standard interval, the standard interval including multiple gear standard intervals and air conditioning operations corresponding to each gear standard interval; adjusting the gear standard intervals in the preset standard interval according to the determined interval strategy to obtain a new gear interval; and generating the control interval corresponding to the target relative ranking based on the new gear interval and the air conditioning operations corresponding to each gear standard interval.

[0062] The steps for adjusting the gear standard range within the preset standard range according to the determined range strategy to obtain a new gear range include:

[0063] Within a preset standard range, all boundary values ​​are divided into multiple gear standard ranges. Following the adjustment mode and parameters of the range strategy, all acquired boundary values ​​are calculated to obtain new boundary values. Based on these new boundary values, new gear ranges are derived. Based on these new gear ranges and the corresponding air conditioning operations for each gear standard range, a control range corresponding to the target relative ranking is generated.

[0064] It should be noted that the interval strategy corresponding to rankings within the same preset ranking distribution interval is the same. A target ranking distribution interval for the target relative ranking can be determined within each preset ranking distribution interval, and the interval strategy of the target ranking distribution interval is used as the interval strategy for the target relative ranking. Each preset distribution ranking interval in the preset distribution control mapping relationship can be preset based on actual conditions, and the range obtained by concatenating the preset distribution ranking intervals is 0 to 100%. The interval strategy includes adjustment modes and adjustment parameters; the adjustment modes include increasing and decreasing. The interval strategy can be used to determine the control interval for the target relative ranking. The interval strategies corresponding to each preset ranking distribution interval can be different.

[0065] The standard range can be determined based on the actual situation. The standard range can include multiple standard ranges and the corresponding air conditioning operation for each standard range. Each standard range has its own corresponding standard boundary value.

[0066] For each gear standard range, the boundary values ​​of the gear standard range can be adjusted based on the range strategy to obtain a new gear range. This allows for flexible adjustment of the standard range based on the air quality when the air conditioning equipment is started, making the adjusted control range more effective in regulating air quality and improving the air quality regulation effect.

[0067] For example, a preset standard range can be obtained. Based on a determined range strategy, the boundary values ​​of each gear's standard range within the standard range are adjusted to obtain a new gear range corresponding to each gear's standard range. The adjustment parameter can be an adjustment ratio or a fixed adjustment value. Both the adjustment ratio and the fixed adjustment value can be determined based on the actual situation. For example, the adjustment ratio can be 5% or 10%, and the fixed adjustment value can be 50 or 100, etc. This embodiment does not impose specific limitations on these.

[0068] Each gear standard range has its own corresponding standard boundary value. Each gear standard range can include two standard boundary values. The largest boundary value within the same gear standard range can be represented as the opening threshold, and the smallest boundary value is the closing threshold. When the air quality is less than or equal to the opening threshold of the gear standard range and greater than the closing threshold of the same gear standard range, the air conditioning equipment can operate the air conditioning operation corresponding to the gear standard range.

[0069] The adjustment mode and adjustment parameters in the interval strategy for each preset distribution interval can be predetermined. For example, the adjustment mode of the interval strategy can be either adjustment ratio or adjustment to a fixed value, with the adjustment mode being "increase". Alternatively, the interval strategy can also have an adjustment mode of either adjustment ratio or adjustment to a fixed value, with the adjustment mode being "decrease". When the adjustment mode is "decrease", all boundary values ​​corresponding to each gear's standard interval can be reduced based on the adjustment parameters. When the adjustment mode is "increase", all boundary values ​​corresponding to each gear's standard interval can be increased based on the adjustment parameters.

[0070] For example, when the adjustment parameter is the adjustment ratio, the product of all boundary values ​​corresponding to each standard range of each gear and the adjustment ratio can be calculated to obtain the new boundary value corresponding to each boundary value. When the adjustment mode is small, the adjustment ratio is less than 1. When the adjustment mode is large, the adjustment ratio is greater than 1.

[0071] When the adjustment parameter is a fixed value and the adjustment mode is set to "small", for each boundary value within each gear standard range, the absolute value of the difference between the boundary value and the fixed adjustment value is calculated to obtain a new boundary value. When the adjustment parameter is a fixed value and the adjustment mode is set to "large", for each boundary value within each gear standard range, the sum of the boundary value and the fixed adjustment value is calculated to obtain a new boundary value. For each gear standard range, the new boundary values ​​obtained by calculating all boundary values ​​within the gear standard range according to the adjustment mode and adjustment parameter determine a new gear range composed of these new boundary values.

[0072] In one embodiment, by adjusting the mode and parameters, the standard range can be flexibly adjusted, thereby facilitating the determination of new gear ranges and improving the flexibility of standard range adjustment. Different adjustment modes and parameters can be used to determine multiple control ranges, thus adapting to control ranges corresponding to different air qualities, enabling more comprehensive and effective air quality regulation.

[0073] Step S20: Obtain the operating gear of the previous cycle;

[0074] It should be noted that the previous cycle is adjacent to the current cycle, and the time of the previous cycle is earlier than the corresponding time of the current cycle. The operating setting is the control setting of the air conditioning equipment in the previous cycle. Since the air conditioning equipment still maintains the operating setting of the previous cycle before the setting is changed, the current control setting of the air conditioning equipment can also be directly obtained as the operating setting.

[0075] For example, the air quality detected in the previous cycle can be obtained, and the control level corresponding to the air quality in the previous cycle, which can be found in the mapping relationship, can be used as the operating level.

[0076] Step S30: Compare the operating gear and the control gear, and control the operation of the air conditioning equipment according to the comparison result.

[0077] It should be noted that the comparison result is a comparison between the operating gear and the control gear. The comparison result can be that the operating gear and the control gear are the same, the operating gear's adjustment intensity is greater than the control gear's adjustment intensity, or the operating gear's adjustment intensity is less than the control gear's adjustment intensity. Adjustment intensity can be used to describe the degree to which the air conditioning equipment adjusts air quality.

[0078] For example, the adjustment intensity corresponding to the operating gear and the control gear are compared, and the operation of the air conditioning equipment is controlled according to the comparison result of the operating gear and the control gear.

[0079] This embodiment detects the air quality of an air conditioning device in the current cycle, obtains the control setting corresponding to the air quality in the current cycle, and obtains the operating setting of the previous cycle. Based on the comparison between the operating setting and the control setting, the air conditioning device is controlled to operate. Because this embodiment can compare the settings (control setting and operating setting) of two adjacent cycles (the current cycle and the previous cycle), it can control the air conditioning device based on the comparison result. This avoids directly controlling the air conditioning device based on the control setting corresponding to the air quality in the current cycle. Instead, before switching settings, it compares the operating setting and the control setting, and then controls the air conditioning device based on the comparison result. This helps avoid the air conditioning device switching back and forth between the control setting and the operating setting when the air quality is at the critical point between adjacent settings, thereby improving the stability of the air conditioning device's operation.

[0080] Referring to Figure 7, in one embodiment, step S30 further includes step S31: when the adjustment intensity of the control gear is greater than the adjustment intensity of the operating gear, the air conditioning device is controlled to operate at the control gear.

[0081] When the adjustment intensity of the control setting is greater than that of the operating setting, it indicates that the air conditioning equipment needs to switch from a lower adjustment intensity setting to a higher one. This also suggests that the air quality in the environment where the air conditioning equipment is located has deteriorated. Therefore, in this situation, the air conditioning equipment can be directly controlled to operate at the control setting to quickly adjust the air quality in the environment with a higher adjustment intensity, thereby improving the air conditioning effect and preventing further deterioration of air quality.

[0082] Referring to Figure 7, in one embodiment, step S30 further includes step S32: when the adjustment intensity of the control gear is equal to the adjustment intensity of the operating gear, the air conditioning device is controlled to operate at the control gear or the operating gear.

[0083] When the adjustment intensity of the control setting is equal to that of the operating setting, it means that the air conditioning equipment has not changed its setting in two adjacent cycles. This indicates that whether the air conditioning equipment is controlled by the control setting or the operating setting, it can effectively adjust the air quality of the current cycle. It also means that the air quality of the current cycle and the air quality of the previous cycle belong to the same setting range. Therefore, the air conditioning equipment can be controlled to operate at the control setting or the operating setting.

[0084] Referring to Figure 7, in one embodiment, step S30 further includes step S33: when the adjustment intensity of the control gear is less than the adjustment intensity of the operating gear, after controlling the air conditioning device to maintain the operating gear for a preset time, the air conditioning device is controlled to operate at the control gear.

[0085] It should be noted that when the adjustment intensity of the control setting is less than that of the operating setting, it indicates that the air conditioning device needs to switch from a higher adjustment intensity setting to a lower adjustment intensity setting. This also indicates that the air quality in the environment where the air conditioning device is located has improved. Therefore, in this situation, to avoid switching back and forth between adjacent settings, in one embodiment, the air conditioning device is controlled to maintain operation at the operating setting for a preset time before being controlled to operate at the control setting. The preset time can be determined based on actual conditions, and this embodiment does not impose a specific limitation on it.

[0086] It is understandable that the air conditioning equipment can be controlled to run at a high setting for a preset time, and then controlled to run at a low setting.

[0087] When switching to a lower adjustment level, the air quality may deteriorate due to the reduced adjustment intensity, potentially causing the air conditioning unit to switch back and forth between adjacent levels, resulting in unstable switching. Therefore, in one embodiment, if it is detected that the adjustment intensity of the control level is less than that of the operating level, the air conditioning unit is controlled to maintain operation at the operating level for a preset time before being controlled to operate at the control level. This ensures that the air quality stabilizes and improves before switching to a lower adjustment level, thus avoiding the air conditioning unit switching back and forth between adjacent levels.

[0088] Referring to Figure 7, in one embodiment, step S30 further includes step S34: when the adjustment intensity of the control gear is less than the adjustment intensity of the operating gear, the air conditioning device is controlled to maintain the operating gear, and after the air quality reaches the target buffer opening threshold of the operating gear, the air conditioning device is controlled to operate at the control gear.

[0089] It should be noted that when the adjustment intensity of the control setting is less than that of the operating setting, in addition to the implementation method in step S33, the implementation method in step S34 can also be used. In one embodiment, the air conditioning device can still be controlled to operate at the operating setting, and after the air quality reaches the target buffer opening threshold of the operating setting, the air conditioning device can then be controlled to operate at the control setting. This allows the air conditioning device to operate at the operating setting for a period of time, until the air quality stabilizes and improves, before operating at the control setting. This improves the stability of the air conditioning device.

[0090] The target buffer activation threshold for each running gear can be preset or determined based on actual conditions. Each running gear can have two boundary values, and the target buffer activation threshold is the smaller boundary value among the running gears.

[0091] Referring to Figure 2, the control method further includes steps S341 to S344:

[0092] Step S341: Obtain the control range of the air conditioning device. The control range includes multiple control levels, and each control level includes an activation threshold.

[0093] It should be noted that the obtained control range corresponds to the air quality at the time the air conditioning unit is started. The control range of the air conditioning unit can include multiple control levels, each with different adjustment intensities. Each control level has its own corresponding range. The activation threshold of a control level is the minimum boundary value of its corresponding range. A range includes two boundary values; the two boundary values ​​within the same range are different. The minimum boundary value is the activation threshold, and the maximum boundary value is the deactivation threshold. Each control level has its own corresponding activation threshold. The mapping relationship between air quality and control levels can be determined based on the control range of the air conditioning unit. For each control level in the mapping relationship, the corresponding air quality is the air quality between the activation and deactivation thresholds of that control level. The control range is obtained by concatenating the ranges of each control level in the mapping relationship.

[0094] Step S342: Based on the preset adjustment value, reduce the opening threshold of each control position to obtain the buffer opening threshold of each control position.

[0095] It should be noted that the preset adjustment value can be set based on actual conditions; for example, the preset adjustment value could be 100, 50, etc. This embodiment does not impose a specific limitation on this. The activation threshold for each control level needs to be reduced. For example, for any control level, the difference between the control level's activation threshold and the preset adjustment value can be used as the buffer activation threshold. The preset adjustment value is a positive number. Each control level has its own corresponding buffer activation threshold. In other embodiments, the closing threshold of each control gear can be reduced based on a preset adjustment value to obtain the buffer closing threshold of each control gear. This makes it easier to ensure that the interval length of the same control gear remains unchanged. The interval length of the control gear refers to the difference between the two boundary values ​​of the gear interval. For example, if the gear interval of the control gear is [1000, 1250], where 1000 is the opening threshold and 1250 is the closing threshold, and the interval length is 250, after adjusting the control gear based on the preset adjustment value, we can obtain [950, 1200], where 950 is the buffer opening threshold and 1200 is the buffer closing threshold. After the control gear is adjusted, the corresponding interval length is still 250.

[0096] Step S343: Determine the target gear for the operating gear among the various control gears;

[0097] Step S344: Use the buffer opening threshold of the target gear as the target buffer opening threshold.

[0098] It should be noted that the adjustment intensity of the target setting is the same as that of the operating setting. Therefore, the buffer opening threshold of the target setting can be used as the target buffer opening threshold of the operating setting. Since the target buffer opening threshold is relatively smaller than the operating setting's opening threshold, when the adjustment intensity of the current cycle's air quality control setting is less than that of the operating setting, the air conditioning unit maintains its operating setting. Once the air quality reaches the target buffer opening threshold of the operating setting, the air conditioning unit operates based on the current cycle's air quality control setting. This allows the air conditioning unit to maintain operation at a higher adjustment intensity for a period of time. When the air quality is below the target buffer opening threshold, the air conditioning unit operates based on the current cycle's air quality control setting. When the air quality is below the target buffer opening threshold, it can switch to a lower adjustment intensity setting. Even when switching to a lower adjustment intensity setting, if the air quality fluctuates around the target buffer opening threshold, because the target buffer opening threshold is smaller than the operating setting's opening threshold, even if the air quality is slightly higher than the target buffer opening threshold, the air conditioning unit will not switch from the current cycle's air quality control setting to the operating setting, thus ensuring the stability of the switching operation.

[0099] For example, each control zone of the air conditioning device is acquired. For each control level, the difference between the opening threshold and the preset adjustment value is calculated to obtain a buffer opening threshold, and the difference between the closing threshold and the preset adjustment value is calculated to obtain a buffer closing threshold. A target level for the operating level is determined among each control level, and the buffer opening threshold of the target level is used as the target buffer opening threshold. In one embodiment, for two adjacent levels, the closing threshold of the level with lower adjustment intensity is the opening threshold of the level with higher adjustment intensity, and the buffer closing threshold of the level with lower adjustment intensity is the buffer opening threshold of the level with higher adjustment intensity.

[0100] To better understand the relationship between the opening threshold and buffer opening threshold of each control level, please refer to the following table for an example. Taking CO2 as an example, Table 1 shows the mapping relationship between each control level and the corresponding air quality in the control range corresponding to the air quality when the air conditioning equipment is started. Table 2 shows the buffer opening threshold and buffer closing threshold of each control level after adjusting the opening and closing thresholds of each control level in the control range corresponding to the air quality when the air conditioning equipment is started.

[0101] Table 1:

[0102] CO2 (ppm) control levels: Excellent (CO2 ≤ 8000), Good (800 < CO2 ≤ 1000), Good (1000 < CO2 ≤ 1250), Good (1250 < CO2 ≤ 1500), Poor (1500 < CO2), 4th grade.

[0103] Table 2:

[0104] CO2 (ppm) control levels: Excellent (CO2 ≤ 7500), Good (750 < CO2 ≤ 950), Good (950 < CO2 ≤ 1200), Good (1200 < CO2 ≤ 1450), Poor (1450 < CO2), 4th grade.

[0105] In Tables 1 and 2, ppm (parts per million) is a unit representing concentration or proportion. The levels in Tables 1 and 2 describe the air quality level within each control setting range. For example, levels 0 and 1 correspond to excellent air quality, levels 2 and 3 to good air quality, and level 4 to poor air quality. Levels 0 to 4 represent the control settings for air conditioning equipment. Referring to Table 1, for example, air quality less than or equal to 800 corresponds to level 0; air quality greater than 800 but less than or equal to 1000 corresponds to level 1; air quality greater than 1000 but less than or equal to 1250 corresponds to level 2; air quality greater than 1250 but less than or equal to 1500 corresponds to level 3; and air quality greater than 1500 corresponds to level 4. Determining the control level for the air quality in the current cycle is based on the mapping relationship between the control level and the corresponding controlled quality within the control range corresponding to the air quality when the air conditioning equipment is started. For example, in this case, the control level for the air quality in the current cycle can be determined by referring to Table 1. In one embodiment, the control level with the smallest boundary value can be used as the opening threshold, and the control level with the largest boundary value can be used as the closing threshold. For example, level 0 includes a closing threshold, and the closing threshold for level 0 is 800; level 1 has an opening threshold of 800 and a closing threshold of 1000; level 2 has an opening threshold of 1000 and a closing threshold of 1250; level 3 has an opening threshold of 1250 and a closing threshold of 1500; and level 4 has an opening threshold of 1500.

[0106] Table 2 shows the gear ranges corresponding to each control gear after adjusting the opening and closing thresholds of each control gear in Table 1. Referring to Table 2, the buffer opening threshold for gear 0 is 750, the buffer opening threshold for gear 1 is 800, and the buffer closing threshold is 1000; the buffer opening threshold for gear 2 is 1000, and the buffer closing threshold is 1250; the buffer opening threshold for gear 3 is 1250, and the buffer closing threshold is 1500; and the buffer opening threshold for gear 4 is 1500.

[0107] To better understand this embodiment, please refer to Figure 3 for a brief description of the gear switching process. In this example, we will use the example that the higher the gear, the greater the adjustment intensity, and the lower the gear, the smaller the adjustment. In other embodiments, it can also be set that the lower the gear, the lower the adjustment intensity, etc., and this embodiment does not specifically limit this. The air conditioning device is turned on, and the air quality is periodically detected. The air quality Vi of the i-th cycle is obtained, and the control gear Di corresponding to Vi is obtained. Di is compared with the operating gear Di-1 of the previous cycle. If Di-Di-1>0, the gear is changed from low to high, and the system operates based on the control gear Di, so that a stronger adjustment capability is activated when the air quality deteriorates, thus preventing air quality from worsening. If Di-Di-1=0, the system operates based on the operating gear Di-1, indicating that the operating gear is reasonable, and the air can continue to be adjusted based on this gear. If Di-Di-1<0, the gear is changed from high to low. After the operating gear Di-1 has been running for a preset time, the system operates according to Di, or when the air quality is less than the target buffer opening threshold of the operating gear Di-1, the system operates according to Di. This can avoid frequent starting and stopping of air conditioning equipment, or switching between adjacent settings.
