Description

Technical Field

[0001] The present application relates to the technical field of air conditioning equipment control, and particularly to a control method for air conditioning equipment, an air conditioning equipment, and a storage medium. Background Art

[0002] Air conditioning equipment usually has an unavailable resonance frequency range, that is, the air conditioning equipment will not operate at any frequency within this resonance frequency range except the maximum frequency and the minimum frequency. If the frequency that the air conditioning equipment needs to use at this time (i.e., the control frequency) falls within the resonance frequency range, usually, the maximum frequency or the minimum frequency within this resonance frequency range is selected to control the operation of the air conditioning equipment, or the maximum frequency and the minimum frequency are alternately used to control the operation of the air conditioning equipment.

[0003] However, if the maximum frequency is selected to control the operation of the air conditioning equipment, it will not only increase the power consumption of the air conditioning equipment, but also cause the indoor environmental temperature to be relatively lower than the target temperature; if the minimum frequency is selected to control the operation of the air conditioning equipment, it will cause the indoor environmental temperature to be relatively higher than the target temperature; if the maximum frequency and the minimum frequency are alternately used to control the operation of the air conditioning equipment, the service life of the compressor of the air conditioning equipment will be affected due to the too frequent switching of the control frequency. In summary, currently, when the control frequency of the air conditioning equipment falls within the resonance frequency range, the control effect on the air conditioning equipment is poor. Summary of the Invention

[0014] When the difference between the control frequency and the maximum frequency is small, controlling the air conditioning device to first operate at the maximum frequency for the first running time and then at the minimum frequency for the second running time;

[0015] When the difference between the control frequency and the minimum frequency is small, controlling the air conditioning device to first operate at the minimum frequency for the second running time and then at the maximum frequency for the first running time.

[0016] Optionally, the steps of controlling the air conditioning device to operate at the maximum frequency for the first running time and at the minimum frequency for the second running time include:

[0017] Controlling the air conditioning device to first continuously operate at the maximum frequency for the first running time and then continuously operate at the minimum frequency for the second running time.

[0018] Optionally, the control method of the air conditioning device further includes:

[0019] When the control frequency of the air conditioning device is outside the preset resonance frequency range, operating at the obtained control frequency.

[0020] Optionally, the control method of the air conditioning device further includes:

[0021] After the air conditioning device operates for the preset time, returning to execute the step of obtaining the control frequency of the air conditioning device; the preset time is the sum of the first running time and the second running time.

[0022] Optionally, obtaining the control frequency of the air conditioning device includes:

[0023] Obtain the current ambient temperature;

[0024] Based on a preset PID control frequency relationship table, obtain the PID control frequency corresponding to the current ambient temperature as the control frequency of the air conditioning device.

[0025] Optionally, the obtaining of the control frequency of the air conditioning device includes:

[0026] Obtain at least two of the current ambient parameters, operating parameters, and set parameters;

[0027] Based on a preset frequency model, use the obtained parameters as inputs and calculate the control frequency of the air conditioning device.

[0028] This application also provides a control device for an air conditioning device. The control device for the air conditioning device includes:

[0029] An obtaining module, configured to obtain the control frequency of the air conditioning device;

[0030] A determining module, configured to determine the first operating time when the air conditioning device operates at the maximum frequency within a preset resonance frequency range and the second operating time when the air conditioning device operates at the minimum frequency within the preset resonance frequency range when the control frequency of the air conditioning device is within the preset resonance frequency range;

[0035] The present application provides a control method for an air conditioning device. First, the control frequency of the air conditioning device is obtained. When the control frequency of the air conditioning device is within a preset resonance frequency range, the first running time when the air conditioning device operates at the maximum frequency within the preset resonance frequency range and the second running time when the air conditioning device operates at the minimum frequency within the preset resonance frequency range are determined. Then, the air conditioning device is controlled to operate at the maximum frequency for the first running time and at the minimum frequency for the second running time.

[0036] Therefore, when the control frequency of the air conditioning device falls within the preset resonance frequency range, the control method adopted in the present application is not simply to control the operation of the air conditioning device at the maximum frequency or the minimum frequency, but to determine the first running time when the air conditioning device operates at the maximum frequency and the second running time when the air conditioning device operates at the minimum frequency, so as to control the operation of the air conditioning device step by step through the running durations of the maximum frequency and the minimum frequency respectively, thereby ensuring that the indoor environmental temperature is stably maintained at the target temperature through more refined control. In addition, since there is only one switching frequency between the maximum frequency and the minimum frequency, the impact on the service life of the compressor of the air conditioning device caused by frequent switching of the control frequency can be avoided. Furthermore, by reasonably allocating the running durations of the maximum frequency and the minimum frequency of the air conditioning device, the air conditioning device can obtain the same control effect as that of the control frequency operating within the resonance frequency range. It can be seen that the present application solves the technical problem of poor control effect on the air conditioning device when the control frequency of the air conditioning device falls within the resonance frequency range, and improves the control effect on the air conditioning device by realizing refined control.

[0045] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] An air conditioning equipment usually has an unavailable resonance frequency range, that is, the air conditioning equipment will not operate at any frequency within this resonance frequency range except the maximum frequency and the minimum frequency. And if the frequency that the air conditioning equipment needs to use at this time (i.e., the control frequency) falls within the resonance frequency range, at this time, usually the maximum frequency or the minimum frequency within this resonance frequency range is selected to control the operation of the air conditioning equipment, or the maximum frequency and the minimum frequency are alternately used to control the operation of the air conditioning equipment.

[0047] However, if the maximum frequency is selected to control the operation of the air conditioning equipment, it will not only increase the power consumption of the air conditioning equipment, but also cause the indoor environmental temperature to be relatively lower than the target temperature; if the minimum frequency is selected to control the operation of the air conditioning equipment, it will cause the indoor environmental temperature to be relatively higher than the target temperature; if the maximum frequency and the minimum frequency are alternately used to control the operation of the air conditioning equipment, it will affect the service life of the compressor of the air conditioning equipment due to the too frequent switching of the control frequency. In summary, currently, when the control frequency of the air conditioning equipment falls within the resonance frequency range, the control effect on the air conditioning equipment is poor.

[0048] Based on this, the present application proposes a control method for the air conditioning equipment in the first embodiment. Please refer to Figure 1 , the control method for the air conditioning equipment includes:

[0049] Step S10, obtain the control frequency of the air conditioning device;

[0050] In this embodiment, the air conditioning device may be the execution subject of the control method of the air conditioning device. The air conditioning device refers to a device that processes the air in the working space to keep the set temperature, humidity in the working space and control the dust and harmful gas content in the working space. The air conditioning device may be an air conditioner, an air dehumidifier, an air humidifier, etc. This embodiment does not make specific limitations on this.

[0051] It should be noted that the control frequency refers to the frequency that the air conditioning device needs to use at the current moment. When obtaining the control frequency of the air conditioning device, from the perspective of obtaining the frequency, it can be obtained in real time or periodically; from the perspective of the obtaining path, it can be obtained from the air conditioning device or from an external device connected to the air conditioning device. This embodiment does not make specific limitations on the obtaining method of the control frequency of the air conditioning device.

[0052] Step S20, when the control frequency of the air conditioning device is within the preset resonance frequency range, determine the first running time when the air conditioning device runs at the maximum frequency within the preset resonance frequency range and the second running time when the air conditioning device runs at the minimum frequency within the preset resonance frequency range;

[0053] It should be noted that the preset resonance frequency range is used to represent the frequency range in which the air conditioning device cannot operate. The number of preset resonance frequency ranges can be one or more. This embodiment does not make specific limitations on this. It can be understood that usually, there is at least one resonance frequency range for the air conditioning device, especially in the low frequency band. When the air conditioning device runs at a frequency within the resonance frequency range, obvious jitter and noise will occur in the compressor of the air conditioning device, which will affect the service life of the compressor. Therefore, usually the air conditioning device will not work at any frequency within this resonance frequency range. For example, it can be referred to Figure 2 , it can be assumed that the preset resonance frequency range of the air conditioning device is (9Hz, 11Hz).

[0054] In addition, it should be noted that the first running time is used to represent the time for the air conditioning device to run at the maximum frequency within the preset resonance frequency range, and the second running time is used to represent the time for the air conditioning device to run at the minimum frequency within the preset resonance frequency range. It can be understood that if the preset resonance frequency range includes the upper boundary frequency, the maximum frequency of the preset resonance frequency range is the upper boundary frequency; if the preset resonance frequency range does not include the upper boundary frequency, the maximum frequency of the preset resonance frequency range is the frequency that is only lower than the upper boundary frequency within the preset resonance frequency range. If the preset resonance frequency range includes the lower boundary frequency, the minimum frequency of the preset resonance frequency range is the lower boundary frequency; if the preset resonance frequency range does not include the lower boundary frequency, the minimum frequency of the preset resonance frequency range is the frequency that is only higher than the lower boundary frequency within the preset resonance frequency range.

[0055] When determining the first running time when the air conditioning device runs at the maximum frequency within the preset resonance frequency range and the second running time when the air conditioning device runs at the minimum frequency within the preset resonance frequency range, two default times can be set first, that is, the first default time and the second default time are set, where the first default time is greater than the second default time. Then, determine the smaller value of the difference between the control frequency and the maximum frequency and the difference between the control frequency and the minimum frequency. If the difference between the control frequency and the maximum frequency is smaller, then use the first default time as the first running time when the air conditioning device runs at the maximum frequency within the preset resonance frequency range, and use the second default time as the second running time when the air conditioning device runs at the minimum frequency within the preset resonance frequency range. If the difference between the control frequency and the minimum frequency is smaller, then use the second default time as the first running time when the air conditioning device runs at the maximum frequency within the preset resonance frequency range, and use the first default time as the second running time when the air conditioning device runs at the minimum frequency within the preset resonance frequency range. In other embodiments, the first running time and the second running time can also be calculated according to a certain calculation method, and this embodiment does not make specific limitations on this.

[0056] It can be understood that when the control frequency of the air conditioning device is within the preset resonance frequency range, it means that the air conditioning device will not run at the frequencies that need to be used at this time. Then, certain strategies need to be adopted to enable the indoor environmental temperature to reach the target temperature. At this time, if the control frequency changes suddenly, it will affect the service life of the compressor of the air conditioning device. Therefore, it is necessary to give priority to using the control frequencies with a smaller change range and available for the air conditioning device to run to control the air conditioning device. For the situation where the control frequency is within the preset resonance frequency range, the frequencies that meet the conditions of having a smaller change range and being available for the air conditioning device to run at this time are the maximum frequency and the minimum frequency of the preset resonance frequency range. Therefore, the maximum frequency and the minimum frequency of the preset resonance frequency range need to be used to control the air conditioning device.

[0057] Step S30: Control the air conditioning device to operate at the maximum frequency for a first operating time and at the minimum frequency for a second operating time.

[0058] When controlling the air conditioning device to operate at the maximum frequency for a first operating time and at the minimum frequency for a second operating time, regarding the operating sequence of the maximum frequency and the minimum frequency, it can first operate at the maximum frequency and then at the minimum frequency, or it can first operate at the minimum frequency and then at the maximum frequency. The specific operating sequence can be determined according to actual requirements or according to the set default sequence. This embodiment does not make specific limitations on this.

[0059] The embodiment of the present application provides a control method for an air conditioning device. The embodiment of the present application first obtains the control frequency of the air conditioning device. When the control frequency of the air conditioning device is within the preset resonance frequency range, determine the first operating time when the air conditioning device operates at the maximum frequency within the preset resonance frequency range, and the second operating time when the air conditioning device operates at the minimum frequency within the preset resonance frequency range. Then, control the air conditioning device to operate at the maximum frequency for the first operating time and at the minimum frequency for the second operating time. Therefore, when the control frequency of the air conditioning device is within the preset resonance frequency range, the control method adopted in the embodiment of the present application is not to simply control the operation of the air conditioning device at the maximum frequency or the minimum frequency, but to determine the first operating time when the air conditioning device operates at the maximum frequency and the second operating time when it operates at the minimum frequency, and control the operation of the air conditioning device through the respective operating durations of the maximum frequency and the minimum frequency, so as to ensure that the indoor environmental temperature is stably maintained at the target temperature through more refined control. In addition, since there is only one switching frequency between the maximum frequency and the minimum frequency, the influence on the service life of the compressor of the air conditioning device caused by frequent switching of the control frequency can be avoided. Furthermore, the embodiment of the present application rationally distributes the operating durations of the maximum frequency and the minimum frequency of the air conditioning device, so that the air conditioning device can obtain the same control effect as when operating at the control frequency within the resonance frequency range. It can be seen that the embodiment of the present application solves the technical problem of poor control effect on the air conditioning device when the control frequency of the air conditioning device is within the resonance frequency range, and improves the control effect on the air conditioning device by realizing refined control.

[0060] In a possible implementation manner, the step S20: determining the first operating time when the air conditioning device operates at the maximum frequency within the preset resonance frequency range and the second operating time when the air conditioning device operates at the minimum frequency within the preset resonance frequency range includes:

[0061] Step S21: Calculate the deviation rates of the control frequency from the maximum frequency and the minimum frequency respectively according to the control frequency of the air conditioning device, the maximum frequency and the minimum frequency within the preset resonance frequency range.

[0062] It should be noted that the deviation rate is used to characterize the frequency interval distance of the control frequency relative to the maximum frequency and the minimum frequency within the resonance frequency range.

[0063] As an example, in step S21: Calculate the deviation rates of the control frequency from the maximum frequency and the minimum frequency respectively according to the control frequency of the air conditioning device, the maximum frequency and the minimum frequency within the preset resonance frequency range, including: calculating the difference between the maximum frequency within the preset resonance frequency range and the control frequency of the air conditioning device to obtain the first frequency difference, and calculating the difference between the maximum frequency and the minimum frequency within the preset resonance frequency range to obtain the second frequency difference; calculating the ratio of the first frequency difference to the second frequency difference to obtain the deviation rate of the control frequency from the maximum frequency; calculating the difference between 1 and the deviation rate of the control frequency from the maximum frequency to obtain the deviation rate of the control frequency from the minimum frequency. The specific calculation formulas are as follows:

[0064]

[0065] Pl = 1 - Ph

[0066] Where, Fh is the maximum frequency within the preset resonance frequency range, Fl is the minimum frequency within the preset resonance frequency range, Fr is the control frequency of the air conditioning device, Ph is the deviation rate of the control frequency from the maximum frequency, and Pl is the deviation rate of the control frequency from the minimum frequency.

[0067] Step S22: Calculate the first running time and the second running time according to the preset running time and the deviation rate; the sum of the first running time and the second running time is the preset running time.

[0068] As an example, in step S22: Calculate the first running time and the second running time according to the preset running time and the deviation rate, including: calculating the product of the deviation rate of the control frequency from the minimum frequency and the preset running time to obtain the first running time, and calculating the product of the deviation rate of the control frequency from the maximum frequency and the preset running time to obtain the second running time. The specific calculation formulas are as follows:

[0069] Th = Pl * T

[0070] Tl = Ph * T

[0071] Where, Th is the first running time, Tl is the second running time, T is the preset running time, Ph is the deviation rate of the control frequency from the maximum frequency, and Pl is the deviation rate of the control frequency from the minimum frequency.

[0072] In this embodiment, the deviation rates of the control frequency from the maximum frequency and the minimum frequency within the preset resonance frequency range are calculated respectively, and the first running time and the second running time are calculated through the deviation rates of the control frequency from the maximum frequency and the minimum frequency respectively and the preset running time, so that the air conditioning equipment can operate at the maximum frequency and the minimum frequency for a reasonable running duration in combination with the actual situation, thereby improving the reliability of the air conditioning equipment and further improving the control effect on the air conditioning equipment.

[0073] In a possible implementation manner, step S30: controlling the air conditioning equipment to operate at the maximum frequency for the first running time and at the minimum frequency for the second running time includes:

[0074] Step S31, determining the smaller value between the difference between the control frequency and the maximum frequency and the difference between the control frequency and the minimum frequency;

[0075] Step S32, when the difference between the control frequency and the maximum frequency is small, controlling the air conditioning equipment to first operate at the maximum frequency for the first running time and then at the minimum frequency for the second running time;

[0076] It can be understood that if the difference between the control frequency and the maximum frequency is small, it means that the control frequency is closer to the maximum frequency at this time, so the air conditioning equipment can be controlled to first operate at the maximum frequency for the first running time and then at the minimum frequency for the second running time.

[0077] Step S33, when the difference between the control frequency and the minimum frequency is small, controlling the air conditioning equipment to first operate at the minimum frequency for the second running time and then at the maximum frequency for the first running time.

[0078] It can be understood that if the difference between the control frequency and the minimum frequency is small, it means that the control frequency is closer to the minimum frequency at this time, so the air conditioning equipment can be controlled to first operate at the minimum frequency for the second running time and then at the maximum frequency for the first running time.

[0079] In this embodiment, by determining the smaller value between the difference between the control frequency and the maximum frequency and the difference between the control frequency and the minimum frequency to determine the running order of the maximum frequency and the minimum frequency, from the perspective of improving the user experience, running the frequency closer to the control frequency first can make the change of the indoor environmental temperature relatively smooth, that is, the indoor environmental temperature can change with a smaller change amplitude, so from the user's sensory experience, the user will not feel a strong change in the indoor environmental temperature.

[0080] In another possible implementation manner, step S30: controlling the air conditioning device to operate at the maximum frequency for a first operating time and at the minimum frequency for a second operating time includes:

[0081] Step S34, controlling the air conditioning device to continuously operate at the maximum frequency for the first operating time and then continuously operate at the minimum frequency for the second operating time.

[0082] In this embodiment, when controlling the air conditioning device to operate at the maximum frequency and the minimum frequency, regarding the operating sequence of the maximum frequency and the minimum frequency, it can first operate at the maximum frequency and then at the minimum frequency. Since the greater the control frequency, the faster the air conditioning device adjusts the indoor environmental temperature, operating at the maximum frequency first can enable the indoor environmental temperature to reach the target temperature relatively quickly and meet the actual requirements more quickly.

[0083] In a possible implementation manner, the control method of the air conditioning device further includes:

[0084] Step S101, when the control frequency of the air conditioning device is outside the preset resonance frequency range, operating according to the obtained control frequency.

[0085] It can be understood that when the control frequency of the air conditioning device is outside the preset resonance frequency range, it means that the air conditioning device can operate at the frequency required at this time, so the air conditioning device can be normally controlled to operate at the required frequency.

[0086] In a possible implementation manner, the control method of the air conditioning device further includes:

[0087] Step S40, after the air conditioning device operates for a preset time, returning to execute the step of obtaining the control frequency of the air conditioning device; the preset time is the sum of the first operating time and the second operating time.

[0088] It should be noted that the preset time is usually not set too short because the switching frequency between the maximum frequency and the minimum frequency is only once based on the preset time, that is, if the control frequency of the air conditioning device is within the preset resonance frequency range, the maximum frequency and the minimum frequency will be switched once within the preset time. Therefore, if the preset time is set too short, it may cause the control frequency to switch too frequently due to the control frequency of the air conditioning device continuously being within the preset resonance frequency range, which will affect the service life of the compressor of the air conditioning device.

[0089] In this embodiment, after the air conditioning device operates for a preset time, the step of obtaining the control frequency of the air conditioning device will be executed again. The preset time is the sum of the first operating time and the second operating time. That is to say, in this embodiment, by periodically obtaining the control frequency of the air conditioning device, the periodic control of the operation of the air conditioning device is realized, so as to avoid the risk of interrupting the operation of the air conditioning device when the control frequency currently being operated is within the preset resonance frequency range, and ensure the operation stability of the air conditioning device.

[0090] In a possible implementation manner, the step S10: obtaining the control frequency of the air conditioning device includes:

[0091] Step A11, obtaining the current ambient temperature;

[0092] It should be noted that the ambient temperature refers to the temperature of the environment where the air conditioning device is located, and the current ambient temperature refers to the temperature of the environment where the air conditioning device is currently located.

[0093] Step A12, based on a preset PID control frequency relationship table, obtaining the PID control frequency corresponding to the current ambient temperature as the control frequency of the air conditioning device.

[0094] It should be noted that the PID (temperature P, temperature I, temperature D) control frequency relationship table is used to represent the mapping relationship between different ambient temperatures and the PID control frequency. When obtaining the PID control frequency corresponding to the current ambient temperature based on the preset PID control frequency relationship table, in fact, the current ambient temperature is mapped in the preset PID control frequency relationship table, and the mapped PID control frequency is the PID control frequency corresponding to the current ambient temperature.

[0095] In this embodiment, first, the current ambient temperature is obtained, and then, based on the preset PID control frequency relationship table, the PID control frequency corresponding to the current ambient temperature is obtained and used as the control frequency of the air conditioning device. Thus, in this embodiment, by pre-setting the PID control frequency relationship table for representing the mapping relationship between different ambient temperatures and the PID control frequency, when obtaining the control frequency of the air conditioning device, the control frequency of the air conditioning device can be quickly mapped from the PID control frequency relationship table directly through the current ambient temperature, so as to improve the acquisition efficiency of the control frequency of the air conditioning device.

[0096] In another possible implementation manner, the step S10: obtaining the control frequency of the air conditioning device includes:

[0097] Step B11: Obtain at least two of the current environmental parameters, operating parameters, and set parameters.

[0098] It should be noted that the environmental parameter refers to the parameter of the environment where the air conditioning device is located, and the current environmental parameter refers to the parameter of the environment where the air conditioning device is located at the current moment. The environmental parameter may include environmental temperature, environmental humidity, etc. The operating parameter is the operating parameter of the air conditioning device, and the operating parameter may include operating frequency, fan speed, operating power, operating time, etc. The set parameter is the operating parameter set for the air conditioning device.

[0099] Step B12: Based on a preset frequency model, use the obtained parameters as inputs to calculate the control frequency of the air conditioning device.

[0100] It should be noted that the frequency model is used to predict and calculate the control frequency by combining the actually input parameters. The frequency model can be obtained through training with historical parameters, and the historical parameters may include historical environmental parameters, historical operating parameters, and historical set parameters.

[0101] In this embodiment, by obtaining at least two of the current environmental parameters, operating parameters, and set parameters, the obtained parameters are used as inputs to a preset frequency model, and the control frequency of the air conditioning device is calculated through this frequency model. It can be seen that in this embodiment, the control frequency of the air conditioning device is determined by combining the actual situation through the frequency model. Compared with the embodiment that uses a PID control frequency relationship table to determine, although the acquisition efficiency is relatively low, the accuracy of the control frequency of the obtained air conditioning device is relatively high.

[0102] Exemplarily, to help understand the technical concept or technical principle of the present application, please refer to Figure 3 , Figure 3 A brief flowchart of the control method for the air conditioning device of the present application is provided. Taking the preset resonance frequency range including the upper boundary frequency and the lower boundary frequency as an example, it is as follows:

[0103] At regular intervals of time T (corresponding to the above preset time), obtain the recommended frequency of use Fr of the air conditioning equipment (corresponding to the above control frequency), and then determine whether the frequency Fr is in the resonance region (corresponding to the above preset resonance frequency range). If it is determined that the frequency Fr is outside the resonance region, control the operation of the air conditioning equipment according to the frequency Fr; if it is determined that the frequency Fr is within the resonance region, calculate the upper boundary deviation rate Ph (corresponding to the deviation rate between the above control frequency and the maximum frequency) and the lower boundary deviation rate Pl (corresponding to the deviation rate between the above control frequency and the minimum frequency) through the frequency Fr, the maximum frequency of the resonance region (corresponding to the upper boundary frequency), and the minimum frequency (corresponding to the lower boundary frequency). Then, calculate the upper boundary operation duration Th through the time T and the lower boundary deviation rate Pl, and calculate the lower boundary operation duration Tl through the time T and the upper boundary deviation rate Ph. Next, the air conditioning equipment can be controlled to operate at the upper boundary frequency Fh (corresponding to the above maximum frequency) for the upper boundary operation duration Th first, and then at the lower boundary frequency Fl (corresponding to the above minimum frequency) for the lower boundary operation duration Tl; or the air conditioning equipment can be controlled to operate at the lower boundary frequency Fl (corresponding to the above minimum frequency) for the lower boundary operation duration Tl first, and then at the upper boundary frequency Fh (corresponding to the above maximum frequency) for the upper boundary operation duration Th.
