Abstract
Description
Technical Field
[0001] This application relates to the field of air conditioning control technology, specifically providing an air conditioning operating frequency control method, system, control device, and storage medium. Background Technology
[0002] Air conditioner operation can be broadly divided into two stages: the unstable control stage and the temperature-reaching operation stage. The unstable control stage refers to the period immediately after the air conditioner is turned on or when the load changes drastically, such as when remote control settings are changed, outside air enters, or a heat source generates heat, resulting in a significant deviation between the ambient temperature and the air conditioner's set temperature. In this stage, the air conditioner operates at full load at the highest frequency corresponding to the ambient temperature range to quickly reach the set temperature. The temperature-reaching operation stage occurs when the ambient temperature has reached the air conditioner's set target temperature. At this point, the air conditioner operates at a lower frequency, and a smaller cooling capacity is sufficient to maintain the ambient temperature.
[0003] Currently, the operating frequency of air conditioners during the temperature-reaching phase is generally pre-programmed and fixed by developers. However, this frequency may not be suitable for all environments. In other words, it may not meet the cooling capacity required to maintain the room temperature under various conditions. For example, the cooling capacity required to maintain the room temperature differs between a house built with double-layered hollow bricks and a metal container model house; the cooling capacity required to maintain the room temperature differs between an outside temperature of 38°C and 28°C; the cooling capacity required to maintain the room temperature differs depending on the number of people in the room and whether there is heat generated by the machine. In at least these scenarios, traditional air conditioner operating frequency control methods switch the air conditioner back and forth between the minimum and maximum frequencies, which can easily lead to power loss and reduced compressor lifespan. Furthermore, large temperature fluctuations within the room can also result in a poor user experience.
[0004] Accordingly, there is a need in the art for a new method, system, control device, and storage medium for controlling the operating frequency of air conditioners to solve the above problems. Summary of the Invention

[0009] In one technical solution of the above-mentioned air conditioner operating frequency control method, the minimum frequency F during the air conditioner operation is based on a preset value. min and maximum frequency F max Obtaining the maximum frequency F0 of the air conditioner in the temperature-controlled operating state includes: setting the minimum frequency F... min The sum is obtained by adding the value to the preset increment, and then setting the maximum frequency F. max Multiply the sum by the percentage of cooling capacity required to reach the preset temperature and calculate the product; select the larger value from the sum and the product value as the maximum frequency F0 of the air conditioner in the temperature-reaching operating state.
[0010] In one of the above technical solutions of the air conditioner operating frequency control method, the difference between the target temperature T and the environment temperature T t is greater than a preset first threshold value, and the first duration during which the difference is greater than the preset first threshold value is recorded; and whether the first duration is greater than a preset first duration is determined, and if so, it is determined that the operating frequency of the air conditioner needs to be adjusted. t

[0019] The above one or more technical solutions of the present application have at least one or more of the following beneficial effects:
[0020] In the implementation of the technical solutions of the present application, if it is determined that the air conditioner in the temperature reaching operating state needs to adjust its operating frequency, a target frequency F is determined between the minimum frequency F min and the maximum frequency F0 x . Through the present application, the operating frequency of the air conditioner can be accurately adjusted to a suitable value according to the actual ambient temperature, without frequently jumping to the maximum frequency F max or the minimum frequency F min , thereby prolonging the service life of the air conditioner and ensuring the temperature maintaining effect in the temperature reaching operating state.
[0021] Further, in the implementation of the technical solutions of the present application, when adjusting the operating frequency of the air conditioner, the real-time frequency F t of the air conditioner at the current time is taken as the reference, and the adjustment is made in different directions according to the size relationship between the ambient temperature T t and the target temperature T.

Through the present application, the setting of the first two running frequencies after the air conditioner enters the temperature reaching running state is used to quickly determine whether the temperature reaching running limit frequency meets the requirement of maintaining the ambient temperature. If the requirement is met, the appropriate running frequency is determined between the minimum frequency F min and the maximum frequency F0. If the requirement is not met, for example, the actual environment changes suddenly, other ways such as exiting the temperature reaching running state and running at a higher frequency to maintain the ambient temperature can be adopted.
[0023] Further, in the implementation of the technical solution of the present application, the minimum frequency F min and the maximum frequency F max are obtained to be reasonable values within the interval as the upper limit of the temperature reaching running frequency.

[0024] Further, in the implementation of the technical solution of the present application, the temperature change and the duration are combined to determine whether the running frequency needs to be adjusted.

[0034] Referring to the drawings Figure 1 , Figure 1 is a schematic diagram of main steps of an air conditioner operating frequency control method according to an embodiment of the present application. As shown in Figure 1 , the air conditioner operating frequency control method in the embodiment mainly includes the following steps S1-S4.
[0035] Step S1: based on the preset minimum frequency F min and maximum frequency F max in the air conditioner operating process, the maximum frequency F0 of the air conditioner in the temperature reaching operating state is obtained.
[0036] In the embodiment, the minimum frequency F min and the maximum frequency F maxGenerally, the fixed value is set by the air conditioner before leaving the factory, or the minimum operating frequency and the maximum operating frequency of the air conditioner correspond to the temperature interval of the environment, for example, when the environment temperature is between 25℃-29℃, the minimum operating frequency is 20hz and the maximum operating frequency is 40hz, when the environment temperature is between 30℃-34℃, the minimum operating frequency is 25hz and the maximum operating frequency is 49hz, when the environment temperature is between 35℃-40℃, the minimum operating frequency is 30hz and the maximum operating frequency is 54hz, and so on. Therefore, the minimum frequency F min and the maximum frequency F max in the embodiment can also change according to the environment temperature.
[0037] In the embodiment, when the air conditioner is in the temperature reaching operating state, the environment temperature has been basically maintained in the set temperature range, and the environmental factors are relatively stable. Therefore, the maximum frequency F0 during this period can be lower than the maximum frequency F max , but considering that slight disturbance factors such as the existence of a continuous heat source in the environment can easily lead to a slight temperature rise, the minimum frequency F min to the maximum frequency F0 needs to be adjustable.
[0038] In one embodiment of the embodiment, step S1 can specifically include:
[0039] adding the minimum frequency F min and the preset increment value, and multiplying the maximum frequency F max and the preset temperature reaching required refrigerating capacity percentage; in the sum value and the product value, the value with the larger number is selected as the maximum frequency F0 of the air conditioner in the temperature reaching operating state.
[0040] In the embodiment, the preset increment value is equivalent to the value of the frequency increase again on the basis of the minimum frequency F min . After the frequency is increased, the refrigerating capacity can be increased, so the increment value can be a relatively conservative frequency increase value that can overcome slight disturbance factors. The preset increment value can be pre-set unchanged before the air conditioner leaves the factory, or it can be an empirical value analyzed based on historical data or a preset model, which is not limited in the application. The temperature reaching required refrigerating capacity percentage is the ratio of the minimum refrigerating capacity required to continue to maintain the set temperature to the refrigerating capacity generated by the maximum frequency F max . Similarly, the percentage can be pre-set unchanged before the air conditioner leaves the factory, or it can be an empirical value analyzed based on historical data or a preset model, which is not limited in the application. For example, the preset increment value can be 10hz, and the temperature reaching required refrigerating capacity percentage can be 30%. F min +10 is compared with F maxThe larger of the two values (×30%) is selected as F0. By comparing the two values and selecting the larger one as the maximum frequency F0 of the air conditioner in the temperature-reaching operation state, the goal is to maximize the maximum frequency F0 in the temperature-reaching operation state while avoiding overly aggressive frequency adjustments. This improves the air conditioner's anti-interference capability in the temperature-reaching operation state and further saves energy.
[0041] Continuing with the above appendix Figure 1 The embodiment shown in this application further includes step S2: obtaining the real-time ambient temperature T when the air conditioner is in the temperature-controlled operating state. t .
[0042] In this embodiment, the ambient temperature T t This refers to the ambient temperature when the air conditioner is operating at its target temperature. The specific ambient temperature can be the air temperature of the area surrounding the air conditioner or the air temperature of the target space, such as the dining room connected to the living room if the air conditioner is installed in the living room. Obtain the ambient temperature T. t The method can be continuous and uninterrupted, or it can be performed periodically at fixed time intervals, or it can be set by the user. This application does not limit this.
[0043] In one implementation, the ambient temperature T can be obtained by a temperature sensor installed in the air conditioner or in any area. t Alternatively, ambient temperature can be obtained through temperature sensors in the user's wearable device.
[0044] Continuing with the above appendix Figure 1 The embodiment shown in this application further includes step S3: based on a preset target temperature T and ambient temperature T... t Determine whether the operating frequency of the air conditioner needs to be adjusted when it reaches the set temperature.
[0045] In this embodiment, the preset target temperature T is generally a temperature set by the user. Determining whether the operating frequency of the air conditioner in the temperature-reaching operation state needs adjustment can be based on the ambient temperature T. t The rate of change of the difference between the target temperature and the ambient temperature T is used as a reference. For example, if the rate of temperature change is too large, it can be considered a disturbance, which may have occurred, such as a small amount of warm air entering due to the brief opening of doors or windows. Therefore, it is determined that the operating frequency needs to be adjusted. Alternatively, the ambient temperature T can be used as a reference. t The magnitude of the difference between the target temperature T and the target temperature T.
[0046] In one implementation, step S3 may specifically be as follows:
[0047] Determine the target temperature T and the ambient temperature T twhether the difference is greater than a preset first threshold value, if yes, record a first duration that the difference is greater than the preset first threshold value; judge whether the first duration is greater than a preset first duration, if yes, judge that the operation frequency of the air conditioner needs to be adjusted.
[0048] In the embodiment, the preset first threshold value can be set before factory shipment, can be set by the user according to personal use habits, or can be determined by using historical data or a preset model analysis. The first duration and the preset first duration are the same as the preset first threshold value. For example, the user sets the target temperature to 26.0℃, and the preset first threshold value is 1.5℃. When the ambient temperature is greater than 27.5℃, the duration is recorded. When the ambient temperature is higher than 27.5℃ and lasts for 30 seconds, it is judged that the operation frequency of the air conditioner needs to be adjusted to a higher value. Alternatively, when the ambient temperature is lower than 24.5℃, the duration is recorded. When the ambient temperature is lower than 24.5℃ and lasts for 30 seconds, it is judged that the operation frequency of the air conditioner needs to be adjusted to a lower value.
[0049] In the embodiment, the corresponding relationship between the ambient temperature change and the air conditioner operation state is shown in the accompanying drawings. Figure 3 As shown in the accompanying drawings, since the air conditioner can enter the temperature reaching operation state, it indicates that the environment is relatively stable at this time. Even if a small disturbance occurs, the operation frequency can be adjusted slightly. However, if the disturbance factor increases, for example, the door and window are opened for a long time, which causes a large amount of external hot air to flow in. For this situation, the air conditioner operation frequency control method of the present application further proposes that when the difference is greater than the preset first threshold value, it is further judged whether the difference is greater than a preset third threshold value, if yes, record a third duration that the difference is greater than the preset third threshold value, wherein the preset third threshold value is greater than the preset first threshold value; judge whether the third duration is greater than a preset third duration, if yes, control the air conditioner to exit the temperature reaching operation state. Through the preset third threshold value greater than the preset first threshold value, it can be judged whether the temperature increases sharply. Through the preset third duration, it can be judged whether the maximum frequency F0 of the temperature reaching operation state can still not meet the cooling capacity requirement. For example, the user sets the target temperature to 26.0℃, and the preset third threshold value is 2.0℃. When the ambient temperature is greater than 28.0℃, the duration is recorded. When the ambient temperature is higher than 28.0℃ and lasts for 20 seconds, it is judged that the air conditioner should not continue to work in the temperature reaching operation state at this time, and should exit the state and work at a higher frequency to achieve rapid cooling.
[0050] In the embodiment, the corresponding relationship between the ambient temperature change and the air conditioner operation state is shown in the accompanying drawings. Figure 3The corresponding relationship between the ambient temperature change and the air conditioner running state is shown in the schematic diagram. Since the air conditioner can enter the temperature reaching running state, it indicates that the environment is relatively stable at this time. In order to further improve the technical solutions of the present application, considering the long-term stable environment, or considering that the running frequency may not be very accurate due to possible errors, that is, the refrigerating capacity brought by the current running frequency may be slightly larger than the refrigerating capacity required to maintain the ambient temperature, resulting in an ambient temperature lower than the temperature set by the user, and the lower temperature may affect the user's body comfort, especially during the night sleep state, and the lower body temperature may affect the user's health. In view of this situation, the air conditioner running frequency control method of the present application also proposes: judging whether the difference is greater than a preset second threshold value, if yes, recording a second time length when the difference is greater than the preset second threshold value, wherein the preset second threshold value is greater than the preset first threshold value; judging whether the second time length is greater than a preset second time length, if yes, controlling the compressor of the air conditioner to stop. By the preset second threshold value greater than the preset first threshold value, it can be judged whether the temperature has dropped significantly, and by the preset second time length, it can be judged that the current running frequency exceeds the refrigerating capacity demand, but too frequent adjustment of the running frequency has no practical significance, at this time the compressor can be temporarily stopped, which can maintain the ambient temperature and can appropriately prolong the service life, and the compressor continues to operate after the temperature rises. For example, the user sets the target temperature to 26.0℃, and the preset second threshold value is 1.0℃, then when the ambient temperature is lower than 25.0℃, the duration is recorded, and when the ambient temperature is lower than 25.0℃ and lasts for 20 seconds, it is judged that the compressor can be temporarily stopped at this time, only the air supply function is provided and the ambient temperature is continuously monitored, and the compressor is started again after the temperature rises to 26.0℃ and maintains for 20 seconds.
[0051] Continue with the above-mentioned embodiment Figure 1 The air conditioner running frequency control method of the present application also includes step S4: if yes, determining the target frequency F min between the minimum frequency F x and the maximum frequency F0based on a preset rule, so that the air conditioner runs at the target frequency F x .
[0052] In this embodiment, when it is judged that the air conditioner frequency needs to be adjusted, the value of the frequency that needs to be increased or decreased can be determined according to the difference between the ambient temperature T t and the target temperature T t , or only the target frequency F x is determined according to the ambient temperature T x , or the value of the frequency that needs to be increased or decreased is determined according to the change rate of the difference. However, the final adjusted target frequency F minWithin the range defined by the maximum frequency F0, the frequency adjustment of the air conditioner during operation at the set temperature is ensured to be not too drastic.
[0053] Combined with appendix Figure 2 The flowchart shown illustrates the main steps for determining the target frequency. In this embodiment, step S4 may specifically include:
[0054] Obtain the real-time frequency F of the air conditioner during operation at the set temperature. t If the ambient temperature T t If the temperature is greater than the target temperature T, then at the real-time frequency F t Determine the target frequency F between the maximum frequency F0 and the maximum frequency F0. x If the ambient temperature T t If the temperature is less than the target temperature T, then at the minimum frequency F min To real-time frequency F t Determine the target frequency F between x .
[0055] In this embodiment, when the target frequency F is determined x After that, the real-time frequency F of the air conditioner t That is, corrected to the target frequency F x To facilitate the next adjustment. If the ambient temperature T t If the ambient temperature is greater than the target temperature T, it indicates that the ambient temperature has increased, so the operating frequency needs to be increased; conversely, the same applies if the ambient temperature is lower than the target temperature T.
[0056] In one implementation, the air conditioner operates at a minimum frequency F. min Entering the temperature-controlled operation state, at the air conditioner's real-time frequency F... t For the minimum frequency F min At that time, if the ambient temperature T t If the temperature is greater than the target temperature T, then the maximum frequency F0 is selected as the target frequency F. x In other words, the initial operating frequency of the air conditioner when it reaches the set temperature is the minimum frequency F. min If a temperature rise necessitates frequency adjustment, the operating frequency will be adjusted to the maximum frequency F0. This allows verification of whether continued operation at the set temperature is appropriate. For example, if the air conditioner enters the set temperature operation state at 20Hz, and a temperature rise necessitates frequency adjustment, the operating frequency will be adjusted to the maximum frequency of 30Hz. The air conditioner will then operate at 30Hz and continuously monitor the ambient temperature T. t Once it is determined that the temperature has dropped below the target temperature T, the operating frequency can be adjusted to 25Hz. The air conditioner runs at 30Hz and continuously monitors the ambient temperature T. t If the temperature continues to fall below the target temperature T, the operating frequency can be adjusted to 22 Hz. This setting allows for the determination of a precise operating frequency that matches the actual environmental conditions.
[0057] Based on steps S1-S4 above, and based on the preset minimum frequency F during air conditioner operation... min and maximum frequency F max The maximum frequency F0 of the air conditioner when it reaches the operating temperature is obtained; the real-time ambient temperature T of the air conditioner when it reaches the operating temperature is obtained. t Based on the preset target temperature T and ambient temperature T t Determine whether the operating frequency of the air conditioner needs to be adjusted when it reaches the set temperature; if so, based on preset rules, adjust the frequency to the minimum frequency F. min Determine the target frequency F between the maximum frequency F0 and the maximum frequency F0. x So that the air conditioner operates at the target frequency F x Operation. This application enables precise adjustment of the air conditioner's operating frequency to a suitable value based on the actual ambient temperature, without frequently switching to the maximum frequency F. max Or minimum frequency F min This not only extends the service life of the air conditioner but also ensures the temperature maintenance effect when the air conditioner reaches its operating temperature.
