Control method of air conditioning equipment, air conditioning equipment and storage medium

[0001] This application claims priority to Chinese patent application No. 202311634492.5 filed on November 30, 2023, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of air conditioning equipment control, and in particular to a control method for air conditioning equipment, air conditioning equipment, and a storage medium. Background Art

[0003] After the air-conditioning equipment enters the temperature maintenance section, that is, after the indoor ambient temperature reaches the temperature set by the air-conditioning equipment, if the indoor ambient temperature changes, it may cause the control parameters of the air-conditioning equipment to jump, and if the frequency of changes in the indoor ambient temperature is high, it will further cause the control parameters of the air-conditioning equipment to fluctuate greatly, thereby affecting the service life of the compressor, internal fan, external fan, etc. of the air-conditioning equipment, and thus reducing the service life of the air-conditioning equipment.

[0004] In order to solve the problems caused by the jump of control parameters, at present, the relative continuity of the change of the control parameters of the air conditioning equipment is usually achieved by limiting the single-step step of the control parameters of the air conditioning equipment, that is, limiting the change amplitude of the control parameters of the air conditioning equipment. However, even if the single-step step of the control parameters of the air conditioning equipment is limited, the jitter problem of the control parameters cannot be avoided, and the single-step step method can easily cause the control parameters of the air conditioning equipment to increase or decrease suddenly in a short period of time. Therefore, the existing air conditioning equipment control method cannot accurately control the change amplitude of the control parameters of the air conditioning equipment, resulting in poor control effect on the air conditioning equipment.

[0048] To make the above-mentioned purposes, features, and advantages of the present application more clearly understood, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0049] After the air-conditioning equipment enters the temperature maintenance section, that is, after the indoor ambient temperature reaches the temperature set by the air-conditioning equipment, if the indoor ambient temperature changes, it may cause the control parameters of the air-conditioning equipment to jump, and if the frequency of changes in the indoor ambient temperature is high, it will further cause the control parameters of the air-conditioning equipment to fluctuate greatly, thereby affecting the service life of the compressor, internal fan, external fan, etc. of the air-conditioning equipment, and thus reducing the service life of the air-conditioning equipment.

[0050] In order to solve the problems caused by the jump of control parameters, at present, the relative continuity of the change of the control parameters of the air conditioning equipment is usually achieved by limiting the single-step step of the control parameters of the air conditioning equipment, that is, limiting the change amplitude of the control parameters of the air conditioning equipment. However, even if the single-step step of the control parameters of the air conditioning equipment is limited, the jitter problem of the control parameters cannot be avoided, and the single-step step method can easily cause the control parameters of the air conditioning equipment to increase or decrease suddenly in a short period of time. Therefore, the existing air conditioning equipment control method cannot accurately control the change amplitude of the control parameters of the air conditioning equipment, resulting in poor control effect on the air conditioning equipment.

[0051] Based on this, the present application proposes an embodiment of a control method for air conditioning equipment, referring to FIG1 . The control method for air conditioning equipment includes:

[0052] Step S10, periodically determining the control parameter interval at the current moment;

[0053] In one embodiment, the air conditioning equipment can be the executor of the control method of the air conditioning equipment. The air conditioning equipment refers to a device that processes the air in the working space to maintain the set temperature and humidity in the working space and control the dust and harmful gas content in the working space. The air conditioning equipment can be an air conditioner, an air dehumidifier, an air humidifier, etc. This embodiment does not make specific limitations on this.

[0054] It should be noted that the control parameter range is used to represent the range of values ​​within which the control parameters of the air conditioning equipment can vary at the current moment. The control parameter range includes an operating frequency range, a fan speed range, and the like.

[0055] In addition, it should be noted that when periodically determining the control parameter interval at the current moment, the time period between each interval can be a default time period, or the time period can be adaptively adjusted according to actual needs. This embodiment does not specifically limit this.

[0056] Step S20, obtaining the current control parameters of the air conditioning equipment;

[0057] It should be noted that the control parameters at the current moment can be used to represent the control parameters initially determined to be used by the air conditioning device to adapt to the current indoor ambient temperature change, or can also be used to represent the control parameters used by the air conditioning device at the current moment. This embodiment does not specifically limit this. The control parameters are used to represent relevant parameters for controlling the operation of the air conditioning device. These control parameters may include operating frequency, fan speed, etc. The operating frequency is used to represent the operating frequency of the compressor of the air conditioning device, and the fan speed is used to represent the speed of the internal fan of the air conditioning device. In one embodiment, the control parameters at the current moment are used to represent the control parameters initially determined to be used by the air conditioning device to adapt to the current indoor ambient temperature change. The control parameters at the current moment can be determined by a control parameter prediction model based on the current operating parameters of the air conditioning device and the indoor ambient temperature, or can be determined by a control parameter configuration table that records the corresponding relationship between different indoor ambient temperatures and control parameters. This embodiment does not specifically limit this.

[0058] In addition, it should be noted that when obtaining the control parameters of the air conditioning device at the current moment, they can be obtained from the air conditioning device or from other devices connected to the air conditioning device, and this embodiment does not specifically limit this.

[0059] Step S30, determining a target control parameter of the air conditioning equipment at the current moment based on the control parameter interval and the control parameter at the current moment;

[0060] It should be noted that the target control parameter is used to represent the control parameter ultimately used by the air conditioning equipment to adapt to the change in the current indoor ambient temperature. The target control parameter may include a target operating frequency, a target fan speed, etc., which is not specifically limited in this embodiment.

[0061] Step S40: Control the operation of the air conditioning equipment according to the determined target control parameters.

[0062] The present invention provides a method for controlling an air conditioning device. The method first periodically determines a control parameter interval at a current moment and obtains the control parameter of the air conditioning device at the current moment. Then, based on the control parameter interval and the control parameter at the current moment, the method determines the target control parameter of the air conditioning device at the current moment. Finally, the method controls the operation of the air conditioning device according to the determined target control parameter. The method determines the target control parameter for controlling the air conditioning device by using the control parameter of the air conditioning device at the current moment and the control parameter interval allowed at the current moment. Since the control parameter interval limits the range of values ​​to which the control parameter of the air conditioning device can change at the current moment, the control parameter interval can accurately control the change amplitude of the control parameter of the air conditioning device to ensure that the control parameter of the air conditioning device can maintain a relatively smooth change, thereby avoiding the problem of control parameter jitter and sudden changes in a short period of time. The method solves the technical problem that the existing air conditioning device control method cannot accurately control the change amplitude of the control parameter of the air conditioning device, resulting in poor control effect of the air conditioning device, improves the control effect of the air conditioning device, reduces the impact on the service life of the compressor, internal fan, external fan, etc. of the air conditioning device, and thus increases the service life of the air conditioning device. In addition, by ensuring that the control parameters of the air conditioning equipment can maintain relatively smooth changes, the changes in indoor ambient temperature can also be made relatively gentle, thereby improving the user experience.

[0063] In one possible implementation, step S10: periodically determining the control parameter range at the current moment includes:

[0064] Step S11, obtaining historical control parameters within a preset time period before the current moment;

[0065] It should be noted that the historical control parameters are used to represent the control parameters used by the air conditioning equipment within a preset time period before the current moment. When obtaining the historical control parameters within the preset time period before the current moment, the parameters can be obtained from the air conditioning equipment or from other devices connected to the air conditioning equipment, and this embodiment does not specifically limit this.

[0066] Step S12, calculating an average value of the control parameters within a preset time period before the current moment based on the historical control parameters;

[0067] It should be noted that the average value of the control parameter refers to the average value of each historical control parameter within a preset time before the current moment. The average value of the control parameter may include the average value of the operating frequency, the average value of the fan wind speed, etc. This embodiment does not specifically limit this.

[0068] Step S13: determining the control parameter range at the current moment according to the calculated control parameter average value and offset value.

[0069] It should be noted that the offset value represents the maximum amplitude by which a control parameter of the air conditioning equipment can vary when the control parameter changes relatively smoothly at its average value. This offset value may include an offset value for operating frequency, an offset value for fan speed, and the like, and is not specifically limited in this embodiment.

[0070] As an example, step S13: determining the control parameter range at the current moment based on the calculated control parameter average value and offset value, includes: determining the sum of the control parameter average value and the offset value as the control parameter upper limit value, determining the difference between the control parameter average value and the offset value as the control parameter lower limit value, and obtaining the control parameter range at the current moment based on the control parameter upper limit value and the control parameter lower limit value, wherein the control parameter range may include the control parameter upper limit value and / or the control parameter lower limit value, or may not include the control parameter upper limit value and / or the control parameter lower limit value, and this example does not make specific limitations on this. The control parameter upper limit value may include the operating frequency upper limit value, the fan wind speed upper limit value, etc., and the control parameter lower limit value may include the operating frequency lower limit value, the fan wind speed lower limit value, etc., and this example does not make specific limitations on this.

[0071] In one embodiment, the average value of each historical control parameter within a preset time before the current moment is calculated to obtain the average value of the control parameter within the preset time before the current moment, and the control parameter range at the current moment is determined by the control parameter average value and the offset value. Since the control parameter average value can indicate the overall change of the control parameter of the air-conditioning equipment within the preset time before the current moment, and since the offset value can indicate the maximum amplitude by which the control parameter of the air-conditioning equipment can change when changing relatively smoothly with the control parameter average value, the control parameter range obtained by the control parameter average value and the offset value can indicate the numerical range to which the control parameter can change at the current moment while ensuring that the change of the control parameter is relatively smooth, so that the control parameter range can be used to achieve precise control of the change amplitude of the control parameter, thereby ensuring the smoothness of the change of the air parameter.

[0072] In one possible implementation, step S30 of determining the target control parameter of the air conditioning equipment at the current moment based on the control parameter range and the control parameter at the current moment includes:

[0073] Step S31, determining whether the current control parameter is within the control parameter range;

[0074] Step S32: When the current control parameter is within the control parameter range, the current control parameter is used as the target control parameter;

[0075] It can be understood that if the control parameters at the current moment are within the control parameter range, it means that in order to adapt to the changes in the indoor ambient temperature at the current moment, the control parameters initially determined to be needed by the air conditioning equipment have a smoother change range relative to the control parameters actually used by the air conditioning equipment. Therefore, the control parameters at the current moment can be directly used as the target control parameters.

[0076] Step S33: When the control parameter at the current moment is outside the control parameter interval, a value in the control parameter interval that is closest to the control parameter at the current moment is used as the target control parameter.

[0077] It should be noted that if the control parameter at the current moment is less than the lower limit value of the target control parameter, the lower limit value of the control parameter can be used as the target control parameter; if the control parameter at the current moment is greater than the upper limit value of the target control parameter, the upper limit value of the control parameter can be used as the target control parameter.

[0078] It can be understood that if the control parameters at the current moment are outside the control parameter range, it means that in order to adapt to the changes in the indoor ambient temperature at the current moment, the control parameters initially determined to be needed for the air conditioning equipment have a larger change range relative to the control parameters actually used by the air conditioning equipment. If the air conditioning setting is operated with the control parameters at the current moment, there will be a problem of sudden changes in the control parameters. Therefore, the value in the control parameter range that is closest to the control parameters at the current moment can be used as the target control parameter.

[0079] In one embodiment, when determining the target control parameter of the air conditioning device at the current moment based on the control parameter interval and the control parameter at the current moment, it is first necessary to determine whether the control parameter at the current moment is within the control parameter interval. If the control parameter at the current moment is within the control parameter interval, it indicates that the control parameter initially determined to be used by the air conditioning device to adapt to the change in the current indoor ambient temperature varies more smoothly than the control parameter actually used by the air conditioning device. Therefore, the control parameter at the current moment can be directly used as the target control parameter. If the control parameter at the current moment is outside the control parameter interval, it indicates that the control parameter initially determined to be used by the air conditioning device to adapt to the change in the current indoor ambient temperature varies more significantly than the control parameter actually used by the air conditioning device. If the air conditioning device is operated with the control parameter at the current moment, the control parameter may fluctuate suddenly. Therefore, the value in the control parameter interval that is closest to the control parameter at the current moment can be used as the target control parameter. This ensures that the target control parameter ultimately used to control the operation of the air conditioning device varies more smoothly than the control parameter actually used by the air conditioning device, thereby avoiding the impact of sudden changes in the control parameter on the service life of the air conditioning device. By improving the control effect of the air conditioning device, the service life of the air conditioning device is increased.

[0080] In one possible implementation, the method for controlling the air conditioning equipment further includes:

[0081] Step S21 : periodically acquiring the control parameters of the air conditioning equipment at the current moment, wherein the acquisition period of the control parameters is greater than or equal to the determination period of the control parameter interval.

[0082] In one embodiment, when obtaining the control parameters of the air-conditioning equipment at the current moment, the control parameters of the air-conditioning equipment at the current moment can be periodically obtained according to an acquisition period that is greater than or equal to a determined period of the control parameter interval, so as to periodically control the changes in the control parameters used by the air-conditioning equipment, thereby avoiding the jitter problem of the control parameters caused by frequent changes in the control parameters used by the air-conditioning equipment due to the real-time acquisition of the control parameters of the air-conditioning equipment at the current moment, and further ensuring the smoothness of the changes in the air parameters, so as to further improve the control effect of the air-conditioning equipment.

[0083] Based on the above embodiment of the present application, in another embodiment of the present application, the same or similar contents as the above embodiment can be referred to the above introduction, and no further details will be given later. On this basis, please refer to Figure 2, the control method of the air conditioning equipment further includes:

[0084] Step S01, determining whether the air conditioning equipment is in a stable operation stage;

[0085] It should be noted that the stable operation stage is used to indicate that the air conditioning equipment has entered the temperature maintenance stage.

[0086] Step S02: When the air conditioning equipment is in a stable operation phase, executing the step of periodically determining the control parameter interval at the current moment.

[0087] In one embodiment, before adjusting the control parameters used by the air-conditioning equipment, it is possible to first determine whether the air-conditioning equipment is in a stable operation stage, so that after the air-conditioning equipment is in a stable operation stage, the control parameters used by the air-conditioning equipment can be adjusted, thereby further limiting the usage scenario of the present application, so as to specifically control the specific control process of the air-conditioning equipment when the air-conditioning equipment is in a stable operation stage.

[0088] In one possible implementation, the step S01 of determining whether the air conditioning equipment is in a stable operation phase includes:

[0089] Step S011: Whether the indoor ambient temperature of the air conditioning equipment reaches the target temperature;

[0090] It should be noted that the target temperature is used to represent the temperature set by the air conditioning equipment, and the indoor ambient temperature refers to the temperature of the space where the air conditioning equipment is located.

[0091] Step S012: When the indoor ambient temperature of the air conditioning equipment reaches the target temperature, the air conditioning equipment enters a stable operation phase until the target temperature is adjusted.

[0092] In one embodiment, by judging whether the indoor ambient temperature of the air-conditioning device has reached the target temperature, it can be determined whether the air-conditioning device has entered the stable operation stage. If the indoor ambient temperature of the air-conditioning device has reached the target temperature, it means that the indoor ambient temperature has reached the temperature set by the air-conditioning device, and the air-conditioning device is determined to have entered the stable operation stage. During this period, if the target temperature is adjusted, the air-conditioning device will exit the stable operation stage and needs to be re-judged.

[0093] For example, to help understand the technical concept or technical principle of the present application, if the indoor ambient temperature reaches the target temperature of 26 degrees Celsius 20 minutes after the air conditioning equipment starts cooling, then at the 21st minute, the average operating frequency for the previous ten minutes (minutes 11 to 20) is calculated to be 36 Hz and the average fan speed is 63. Assuming the operating frequency offset is 3 Hz and the fan speed offset is 4, the operating frequency interval can be determined to be [33 Hz, 39 Hz] and the fan speed interval can be determined to be [59, 67]. If the air conditioning equipment's operating frequency at the current moment is 31 Hz and the fan speed is 56, it can be determined that the air conditioning equipment's operating frequency at the current moment is outside the operating frequency interval, and the operating frequency lower limit of the operating frequency interval, 33 Hz, is used as the target operating frequency. If the air conditioning equipment's fan speed at the current moment is outside the fan speed interval, the fan speed lower limit of the fan speed interval, 59, is used as the target fan speed.

[0094] At the 22nd minute of the air conditioning equipment's operation, the average operating frequency for the previous ten minutes (12th to 21st minutes) is calculated to be 35 Hz, and the average fan speed is 61. Therefore, the operating frequency range can be determined to be [32 Hz, 38 Hz], and the fan speed range can be determined to be [57, 65]. If the air conditioning equipment's operating frequency at the current moment is 31 Hz and the fan speed is 56, it can be determined that the air conditioning equipment's operating frequency at the current moment is outside the operating frequency range. In this case, the lower limit of the operating frequency range, 32 Hz, is used as the target operating frequency. If the air conditioning equipment's fan speed at the current moment is outside the fan speed range, the lower limit of the fan speed range, 57, is used as the target fan speed.

[0095] At the 23rd minute of the air conditioning system's operation, the average operating frequency for the previous ten minutes (13th to 22nd minutes) is calculated to be 34 Hz, and the average fan speed is 59. Therefore, the operating frequency range is determined to be [31 Hz, 37 Hz], and the fan speed range is determined to be [55, 63]. If the air conditioning system's operating frequency at the current moment is 31 Hz and the fan speed is 56, it can be determined that the air conditioning system's operating frequency is within the operating frequency range. The current operating frequency of the air conditioning system, 31 Hz, is used as the target operating frequency. If the current fan speed of the air conditioning system is within the fan speed range, the current fan speed of 56 is used as the target fan speed. For more information on the above, please refer to the schematic diagram of the air conditioning system's operating frequency changes in Figure 3.

[0096] Please refer to Figure 4, which provides a brief flow chart of the control method of the air conditioning equipment of the present application. Taking the control parameter as frequency as an example, first, after the air conditioning equipment starts cooling or heating and the indoor ambient temperature reaches the set temperature, at every certain time interval T, the average operating frequency Favg in the past T time is calculated; with the average operating frequency Favg as the center point and H as the offset value, the operating frequency range is obtained as [Favg-H, Favg+H]; then, it is determined whether the operating frequency Fr of the air conditioning equipment at the current moment is greater than the operating frequency Upper limit value Favg+H, if the operating frequency Fr is greater than the operating frequency upper limit value Favg+H, the target operating frequency is determined to be the operating frequency upper limit value Favg+H; if the operating frequency Fr is less than or equal to the operating frequency upper limit value Favg+H and greater than or equal to the operating frequency lower limit value Favg-H, the target frequency is determined to be the operating frequency Fr; if the frequency Fr is less than the operating frequency lower limit value Favg-H, the target operating frequency is determined to be the operating frequency lower limit value Favg-H; finally, the operation of the air conditioning equipment is controlled by the determined target operating frequency.

[0097] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the control method of the air conditioning equipment of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
