[0039] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0040] Air conditioning equipment is an important tool for improving air quality. Air conditioning equipment is usually equipped with multiple gears to meet the use requirements in different environments. However, when the air quality changes in the critical interval of adjacent gears of the air conditioning equipment, it is easy to repeatedly open the adjacent gears alternately, resulting in unstable operation of the air conditioning equipment. Therefore, the present invention periodically detects the air quality of the air conditioning equipment, compares the control gear of the air quality of the current cycle with the operating gear of the air quality of the previous cycle, and controls the operation of the air conditioning equipment based on the comparison result of the control gear and the operating gear, so as to avoid the air conditioning equipment from switching back and forth between adjacent gears.

[0041] In order to overcome the above defects, the present invention provides a control method for air conditioning equipment:

[0042] Based on this, the present invention proposes a control method for an air conditioning device according to a first embodiment. Figure 1 The control method of the air conditioning equipment includes steps S10 to S30:

[0043] Step S10, detecting the air quality of the air conditioning device in the current cycle, and obtaining the control gear corresponding to the air quality in the current cycle;

[0044] It should be noted that the air conditioning equipment can be used for air conditioning, and the air conditioning equipment can be used to adjust the temperature, humidity, carbon dioxide concentration, formaldehyde, PM2.5 (Particulate Matter 2.5) and TOVC (Total Volatile Organic Compounds), etc., which are not specifically limited in this embodiment. The air quality is the air quality of the environment when the air conditioning equipment is started. The air quality can be temperature, humidity, carbon dioxide concentration, formaldehyde concentration, PM2.5 concentration or TOVC concentration, etc., which are not specifically limited in this embodiment.

[0045] The air conditioning equipment may be an air conditioner, an air purification equipment, a fresh air system, a dehumidification equipment or a humidification equipment, etc., and this embodiment does not specifically limit the air conditioning equipment. The air quality can be detected by a sensor.

[0046] The air conditioning device may include a plurality of control gears, each of which corresponds to a different intensity of conditioned air.

[0047] For example, the air conditioning device can detect the air quality according to a preset period, and the preset period can be determined based on actual conditions, for example, 1 minute, 2 minutes, etc., which is not specifically limited in this embodiment. The air quality of the current period can be the latest air quality detected by the air conditioning device, and the control gear of the air quality of the current period is obtained.

[0048] In a feasible embodiment, step S10 further includes steps S11 to S12:

[0049] Step S11, obtaining a mapping relationship between air quality and control gear position;

[0050] Step S12: based on the mapping relationship between air quality and control gear, find out the control gear corresponding to the air quality of the current cycle.

[0051] It should be noted that each control gear included in the air conditioning device has its own corresponding gear interval, and the gear interval includes each air quality corresponding to the control gear, and the mapping relationship includes the relationship between the air qualities corresponding to each control gear of the air conditioning device. For example, the control gears included in the air conditioning device can be 0 to 4 gears in sequence, and the air conditioning device can include 0 to 4 gears, and the gear intervals corresponding to 0 to 4 gears are (0,800], (800,1000], (1000,1250], (1250,1500], (1500,N], where N is a value greater than 1500. When it is detected that the air quality of the current cycle is 1100, the control gear of the air quality of the current cycle is 3 gears.

[0052] This embodiment obtains the control gear corresponding to the air quality of the current cycle through a mapping relationship, thereby facilitating subsequent comparison of the control gear and the operating gear of the current cycle to control the operation of the air conditioning equipment.

[0053] The control interval can be obtained by splicing the gear intervals of each control gear in the same mapping relationship. In other embodiments, the control interval of the same air conditioning device can be based on the change in air quality when the air conditioning device is started. The control interval of the same air conditioning device will not change during the same operation, but the control intervals corresponding to the same air conditioning device in different operation processes may be different. For example, the control interval corresponding to the air quality of the air conditioning device at startup can be obtained. Specifically: based on the target relative ranking of the air quality of the air conditioning device at startup in the preset quality ranking; the control interval corresponding to the target relative ranking is obtained as the control interval of the air conditioning.

[0054] The preset quality ranking sequence includes a sequence of multiple historical air qualities of the same type as the air quality, which are sorted based on the quality. The target relative ranking is characterized by the percentile ranking of the air quality in the preset quality ranking sequence. The target relative ranking can be used to describe the relative quality of the air quality in the preset quality ranking sequence. The control intervals corresponding to different target relative rankings may also be different. Since the target relative ranking can be used to describe the relative quality of the air quality, the corresponding control interval can be determined based on the target relative ranking, so that the control interval matches the relative quality of the air quality, thereby facilitating more effective air regulation based on the control interval and improving the air quality regulation effect.

[0055] The step of determining a preset quality ranking sequence may include: obtaining historical operation data of other air conditioning equipment in the same area as the air conditioning equipment, and determining the historical air quality of each air conditioning equipment from the historical operation data; sorting the historical air quality to obtain a historical quality sequence; determining the ranking percentile of each historical air quality in the historical quality sequence to obtain a preset quality ranking sequence. For example, the values ​​of each historical air quality may be sorted from large to small or from small to large to obtain a historical quality sequence. The preset quality ranking sequence may be obtained by normalizing the historical quality sequence, and the historical quality sequence may be normalized by determining the ranking percentile of each historical air quality in the historical quality sequence. The ranking percentile may be used to describe the relative position of the historical air quality in the historical quality sequence.

[0056] The historical operation data includes the adjustment data of each user. The same air conditioning equipment may have multiple user adjustment data. When the air conditioning is set to the switch adjustment type, the user adjustment data may include the switch quality threshold. When the air conditioning is set to the gear adjustment type, the user adjustment data may also include the gear adjustment thresholds of the air conditioning equipment. The historical air quality may be the switch quality threshold, or it may be the weighted average of the average values ​​of the gear adjustment thresholds, etc.

[0057] The step of obtaining the control interval corresponding to the target relative ranking includes: 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; according to the determined interval strategy, adjusting the gear standard interval in the preset standard interval to obtain a new gear interval; based on the new gear interval and the air conditioning operations corresponding to each gear standard interval, generating the control interval corresponding to the target relative ranking.

[0058] According to the determined interval strategy, the step of adjusting the gear standard interval in the preset standard interval to obtain a new gear interval includes:

[0059] Obtain all boundary values ​​of multiple gear standard intervals in the preset standard interval; calculate all the boundary values ​​obtained according to the adjustment mode and adjustment parameters of the interval strategy to obtain new boundary values; obtain new gear intervals according to the new boundary values. Based on the new gear intervals and the air conditioning operations corresponding to each gear standard interval, generate a control interval corresponding to the target relative ranking.

[0060] It should be noted that the interval strategies corresponding to the rankings within the same preset ranking distribution interval are the same. The target ranking distribution interval of the target relative ranking can be determined in each preset ranking distribution interval, and the interval strategy of the target ranking distribution interval can be used as the interval strategy of the target relative ranking. Each preset distribution ranking interval in the preset distribution control mapping relationship can be set in advance based on actual conditions, and the interval range obtained by splicing each preset distribution ranking interval is 0 to 100%. The interval strategy includes an adjustment mode and an adjustment parameter, and the adjustment mode includes increase and decrease. The interval strategy can be used to determine the control interval of the target relative ranking. The interval strategies corresponding to each preset ranking distribution interval may be different.

[0061] The standard interval may be determined based on actual conditions. The standard interval may include multiple gear standard intervals and air conditioning operations corresponding to each standard interval. Each gear standard interval has a corresponding standard boundary value.

[0062] For each gear standard interval, the boundary value of the gear standard interval can be adjusted based on the interval strategy to obtain a new gear interval. In this way, the standard interval can be flexibly adjusted based on the air quality when the air conditioning equipment is started, so that the adjusted control interval can more effectively adjust the air quality, thereby improving the air quality adjustment effect.

[0063] For example, a preset standard interval can be obtained, and based on a determined interval strategy, the boundary values ​​of the respective gear standard intervals in the standard interval can be adjusted respectively to obtain new gear intervals corresponding to the respective gear standard intervals. The adjustment parameter can be an adjustment ratio, or it can be an adjustment fixed value. Both the adjustment ratio and the adjustment fixed value can be determined based on actual conditions. For example, the adjustment ratio can be 5% or 10%, etc., and the adjustment fixed value can be 50 or 100, etc. This embodiment does not make specific limitations on this.

[0064] Each gear standard interval has its own corresponding standard boundary value, and each gear standard interval can include two standard boundary values. The maximum boundary value in the same gear standard interval can be represented as the opening threshold, and the minimum boundary value is the closing threshold. When the air quality is less than or equal to the opening threshold of the gear standard interval, and the air quality is greater than the closing threshold of the same gear standard interval, the air conditioning equipment can run the air conditioning operation corresponding to the gear standard interval.

[0065] The adjustment mode and adjustment parameters in the interval strategy of each preset distribution interval can be predetermined. For example, the adjustment mode of the interval strategy can be an adjustment mode of adjusting the ratio or adjusting the fixed value, and the adjustment mode is increasing. The interval strategy can also be an adjustment mode of adjusting the ratio or adjusting the fixed value, and the adjustment mode is decreasing. When the adjustment mode is decreasing, all the corresponding boundary values ​​of each gear standard interval can be reduced based on the adjustment parameters. When the adjustment mode is increasing, all the corresponding boundary values ​​of each gear standard interval can be increased based on the adjustment parameters.

[0066] Exemplarily, when the adjustment parameter is the adjustment ratio, the product of all boundary values ​​corresponding to each gear standard interval and the adjustment ratio can be calculated to obtain a new boundary value corresponding to each boundary value. When the adjustment mode is to decrease, the adjustment ratio is a value less than 1, and when the adjustment mode is to increase, the adjustment ratio is a value greater than 1.

[0067] When the adjustment parameter is the fixed value adjustment and the adjustment mode is the small adjustment, for each boundary value of each gear standard interval, the absolute value of the difference between the boundary value and the fixed value adjustment is calculated to obtain the new boundary value of the boundary value; when the adjustment parameter is the fixed value adjustment and the adjustment mode is the large adjustment, for each boundary value of each gear standard interval, the sum of the boundary value and the fixed value adjustment is calculated to obtain the new boundary value corresponding to the boundary value. For each gear standard interval, the new boundary value obtained by calculating all the boundary values ​​of the gear standard interval according to the adjustment mode and the adjustment parameter is used to determine the new gear interval composed of the new boundary values.

[0068] This embodiment can achieve flexible adjustment of the standard interval by adjusting the mode and adjusting the parameters, thereby facilitating the flexible determination of the new gear interval, thereby improving the flexibility of the standard interval adjustment. A variety of control intervals can be determined using different adjustment modes and different adjustment parameters, thereby adapting to the control intervals corresponding to different air qualities, so as to be able to more comprehensively and effectively adjust the air quality.

[0069] Step S20, obtaining the running gear position of the previous cycle;

[0070] 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 time corresponding to the current cycle. The operating gear is the control gear of the air conditioning device in the previous cycle. Since the air conditioning device still maintains the operating gear of the previous cycle before the gear is switched, the control gear of the current operation of the air conditioning device can also be directly obtained as the operating gear.

[0071] Exemplarily, the air quality detected in the previous cycle may be obtained, and the control gear corresponding to the air quality in the previous cycle found in the mapping relationship may be used as the operating gear.

[0072] Step S30, comparing the operating gear and the control gear, and controlling the operation of the air conditioning equipment according to the comparison result.

[0073] It should be noted that the comparison result is the comparison result of the operating gear and the control gear. The comparison result can be that the operating gear is the same as the control gear, or that the adjustment intensity of the operating gear is greater than the adjustment intensity of the control gear, or that the adjustment intensity of the operating gear is less than the adjustment intensity of the control gear. The adjustment intensity can be used to describe the strength of the air conditioning equipment in adjusting the air quality.

[0074] Exemplarily, the adjustment strengths corresponding to the operating gear and the control gear are compared, and the operation of the air conditioning device is controlled according to the comparison result of the operating gear and the control gear.

[0075] The embodiment of the present invention detects the air quality of the air conditioning device in the current cycle, obtains the control gear corresponding to the air quality of the current cycle, and obtains the operating gear of the previous cycle, and controls the operation of the air conditioning device according to the comparison result between the operating gear and the control gear. Since the embodiment of the present invention can compare the gears (control gear and operating gear) corresponding to the two adjacent cycles (the current cycle and the previous cycle), the operation of the air conditioning device can be controlled based on the comparison result, so that the operation of the air conditioning device is not directly controlled based on the control gear corresponding to the air quality of the current cycle, but before the gear of the air conditioning device is switched, the operating gear and the control gear are compared, and then the operation of the air conditioning device is controlled according to the comparison result, so as to avoid the air conditioning device switching back and forth between the control gear and the operating gear when the air quality is at the critical point of the adjacent gears, thereby improving the stability of the operation of the air conditioning device.

[0076] In a feasible 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, controlling the air conditioning device to operate at the control gear.

[0077] When the adjustment intensity of the control gear is greater than the adjustment intensity of the operating gear, it means that the air conditioning equipment needs to switch from a gear with low adjustment intensity to a gear with high adjustment intensity, and it also means that the air quality of the environment where the air conditioning equipment is located has deteriorated. Therefore, in this case, the air conditioning equipment can be directly controlled to operate according to the control gear to quickly adjust the air quality of the environment where the air conditioning equipment is located with a higher adjustment intensity, thereby improving the air conditioning effect and avoiding deterioration of air quality.

[0078] In a feasible 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, controlling the air conditioning device to operate at the control gear or the operating gear.

[0079] When the adjustment intensity of the control gear is equal to the adjustment intensity of the operating gear, it means that the gear of the air-conditioning equipment has not changed in two adjacent cycles, which means that whether the air-conditioning equipment is controlled at the control gear or the operating gear, the air quality of the current cycle can be effectively adjusted, and it also means that the air quality of the current cycle and the air quality of the previous cycle belong to the same gear range, so the air-conditioning equipment can be controlled to operate according to the control gear or the operating gear.

[0080] In a feasible embodiment, step S30 also 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 equipment to maintain the operating gear for a preset time, controlling the air conditioning equipment to operate at the control gear.

[0081] It should be noted that when the adjustment intensity of the control gear is less than the adjustment intensity of the operating gear, it means that the air conditioning device needs to switch from a gear with high adjustment intensity to a gear with low adjustment intensity, and it also means that the air quality of the environment where the air conditioning device is located has improved. Therefore, in this case, in order to avoid switching back and forth between adjacent gears, this embodiment controls the air conditioning device to maintain the operating gear for a preset time, and then controls the air conditioning device to operate according to the control gear. The preset time can be determined based on actual conditions, and this embodiment does not specifically limit this.

[0082] It is understandable that after controlling the air conditioning device to operate at a gear with a high adjustment intensity for a preset period of time, the air conditioning device may be controlled to operate at a gear with a low adjustment intensity.

[0083] When the gear is switched to a gear with lower regulation intensity, the air quality may deteriorate due to the reduced regulation intensity, which may cause the air conditioning device to switch back and forth between two adjacent gears, thereby causing the problem of unstable switching. Therefore, in this embodiment, when it is detected that the regulation intensity of the control gear is less than the regulation intensity of the running gear, the air conditioning device is controlled to maintain the running gear for a preset time, and then the air conditioning device is controlled to operate according to the control gear. In this way, it can be ensured that when the air quality is stable and improved, the gear with lower regulation intensity is switched, thereby avoiding the air conditioning device from switching back and forth between adjacent gears.

[0084] In a feasible embodiment, step S30 also includes step S34: when the adjustment intensity of the control gear is less than the adjustment intensity of the operating gear, the air conditioning equipment 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 equipment is controlled to operate according to the control gear.

[0085] It should be noted that, in the case where the adjustment intensity of the control gear is less than the adjustment intensity of the operating gear, in addition to the implementation in step S33, the implementation in step S34 can also be adopted. In this embodiment, the air conditioning device can still be controlled to operate in the operating gear, and after the air quality reaches the target buffer opening threshold of the operating gear, the air conditioning device can be controlled to operate according to the control gear. It can still be achieved that the air conditioning device is operated in the operating gear for a period of time, and the air quality is stabilized and improved, and then the air conditioning device is operated according to the control gear. Thereby, the stability of the air conditioning device can be improved.

[0086] The target buffer opening threshold value of the operating gear can be preset and can be determined based on actual conditions. The operating gear can correspond to two boundary values, and the target buffer opening threshold value is the minimum boundary value of the operating gear.

[0087] Further, see Figure 2The control method further includes steps S341 to S344:

[0088] Step S341, obtaining a control interval of the air conditioning device, the control interval includes a plurality of control gears, and the control gear includes an opening threshold;

[0089] It should be noted that the acquired control interval is the control interval corresponding to the air quality when the air conditioning equipment is started. The control interval of the air conditioning equipment may include multiple control gears. Different control gears correspond to different adjustment intensities. Each control gear has its own corresponding gear interval. The opening threshold of the control gear is the minimum boundary value of the corresponding gear interval. The gear interval includes two boundary values. The two boundary values ​​in the same gear interval are different. The minimum boundary value is the opening threshold, and the maximum boundary value is the closing threshold. Each control gear has its own corresponding opening threshold. The mapping relationship between air quality and control gear can be determined based on the control interval of the air conditioning equipment. For each control gear in the mapping relationship, the air quality corresponding to the control gear is the air quality between the opening threshold and the closing threshold of the control gear. The gear intervals of each control gear in the mapping relationship are spliced ​​to obtain the control interval.

[0090] Step S342, based on the preset adjustment value, reducing the opening threshold of each control gear to obtain the buffer opening threshold of each control gear;

[0091] It should be noted that the preset adjustment value can be set based on actual conditions. For example, the preset adjustment value can be 100, 50, etc. This embodiment does not specifically limit this. The respective opening threshold of each control gear needs to be reduced. For example, for any control gear, the difference between the opening threshold of the control gear and the preset adjustment value can be used as the buffer opening threshold. The preset adjustment value is a positive number. Each control gear has its own corresponding cache opening threshold. In other embodiments, the closing threshold of each control gear can be reduced based on the preset adjustment value to obtain the buffer closing threshold of each control gear, so as 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, the gear interval of the control gear is [1000,1250], where 1000 is the opening threshold, 1250 is the closing threshold, and the interval length is 250. After adjusting the control gear based on the preset adjustment value, [950,1200] can be obtained, where 950 is the cache opening threshold, and 1200 is the cache closing threshold. After the control gear is adjusted, the corresponding interval length is still 250.

[0092] Step S343, determining a target gear position of the operating gear in each control gear position;

[0093] Step S344: taking the buffer opening threshold of the target gear as the target buffer opening threshold.

[0094] It should be noted that the adjustment intensity of the target gear is the same as the adjustment intensity of the operating gear, so the buffer opening threshold of the target gear can be used as the target buffer opening threshold of the operating gear. Therefore, the target buffer opening threshold is relatively smaller than the opening threshold of the operating gear, and thus when the adjustment intensity of the control gear of the air quality of the current cycle is smaller 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 operated based on the control gear of the air quality of the current cycle, and the air conditioning device can also be maintained in the gear with higher adjustment intensity for a period of time. When the air quality is less than the target buffer opening threshold, the air conditioning device is operated based on the control gear of the air quality of the current cycle, and when the air quality is less than the target buffer opening threshold, it can be switched to the gear with lower adjustment intensity. Even when switching to the gear with lower adjustment intensity, when the air quality changes above and below the target buffer opening threshold, since the target buffer opening threshold is less than the opening threshold of the operating gear, even if the air quality is slightly greater than the target buffer opening threshold, the air conditioning device will not switch from the control gear of the air quality of the current cycle to the operating gear, thereby ensuring the stability of the switching operation.

[0095] Exemplarily, each control interval of the air conditioning device is obtained, and for each control gear, the difference between the opening threshold and the preset adjustment value is calculated to obtain the buffer opening threshold, and the difference between the closing threshold and the preset adjustment value is calculated to obtain the buffer closing threshold, and the target gear of the operating gear is determined in each control gear, and the buffer opening threshold of the target gear is used as the target buffer opening threshold. In this embodiment, for two adjacent gears, the closing threshold of the gear with low adjustment intensity is the opening threshold of the gear with high adjustment intensity, and the buffer closing threshold of the gear with low adjustment intensity is the buffer opening threshold of the gear with high adjustment intensity.

[0096] In order to better understand the relationship between the opening threshold and the cache opening threshold of each control gear, refer to the following table for examples. Taking the air quality of CO2 as an example, Table 1 shows the mapping relationship between each control gear and the corresponding air quality in the control interval 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 gear after adjusting the opening threshold and closing threshold of each control gear in the control interval corresponding to the air quality at startup.

[0101] Among them, ppm (parts per million) in Table 1 and Table 2 is a unit indicating concentration or proportion. The grades in Table 1 and Table 2 are used to describe the quality of the air quality contained in the gear interval corresponding to each control gear. For example, the air quality corresponding to gear 0 and gear 1 is excellent, the air quality corresponding to gear 2 and gear 3 is good, and the control quality corresponding to gear 4 is poor. Gears 0 to 4 are the control gears corresponding to the air conditioning equipment. Referring to Table 1, for example, when the air quality is less than or equal to 800, it corresponds to gear 0, and when the air quality is greater than 800 and less than or equal to 1000, it corresponds to gear 1. When the air quality is greater than 1000 and less than or equal to 1250, it corresponds to gear 2, when the air quality is greater than 1250 and less than or equal to 1500, it corresponds to gear 3, and when the air quality is greater than 1500, it corresponds to gear 4. The control gear for determining the air quality of the current cycle is determined by the mapping relationship between the control gear and the corresponding control quality in the control interval corresponding to the air quality when the air conditioning device is started. For example, in this example, the control gear for the air quality of the current cycle can be determined with reference to Table 1. In this embodiment, the control gear with the smallest boundary value can be used as the opening threshold, and the largest boundary value can be used as the closing threshold. For example, gear 0 includes a closing threshold, the closing threshold of gear 0 is 800, the opening threshold of gear 1 is 800, and the closing threshold is 1000; the opening threshold of gear 2 is 1000, and the closing threshold is 1250, the opening threshold of gear 3 is 1250, the closing threshold is 1500, and the opening threshold of gear 4 is 1500.

[0102] Table 2 shows the gear ranges corresponding to each control gear after adjusting the opening threshold and closing threshold of each control gear in Table 1. Referring to Table 2, the buffer opening threshold of gear 0 is 750, the buffer opening threshold of gear 1 is 800, and the buffer closing threshold is 1000; the buffer opening threshold of gear 2 is 1000, and the buffer closing threshold is 1250; the buffer opening threshold of gear 3 is 1250, and the buffer closing threshold is 1500; the buffer opening threshold of gear 4 is 1500.

[0103] For a better understanding of this embodiment, refer to Figure 3, briefly describe the gear switching process of this embodiment. In this example, the higher the gear, the greater the adjustment intensity, and the lower the gear, the smaller the adjustment, for example, to illustrate. In other embodiments, it can also be set to the case where the lower the gear, the lower the adjustment intensity, etc., and this embodiment does not specifically limit this. Start the air conditioning equipment, periodically detect the air quality, obtain the detected air quality Vi of the i-th cycle, and obtain the control gear Di corresponding to Vi, compare Di with the operating gear Di-1 of the previous cycle, if Di-Di-1>0; the gear is from low to high, and it is operated based on the control gear Di, so that when the air deteriorates, a stronger adjustment ability is turned on to avoid air deterioration; if Di-Di-1=0, it is operated 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 from high to low, and it is operated according to Di after the operating gear Di-1 runs for a preset time, or, when the air quality is less than the target buffer opening threshold of the operating gear Di-1, it is operated according to Di. This can avoid frequent starting and stopping of the air conditioning equipment, or switching back and forth between adjacent gears.
