[0031] This embodiment provides an air conditioning control method that runs on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0032] Figure 2 This is a flowchart of an air conditioning control method according to an embodiment of this application. Figure 2 As shown, the method includes the following steps:
[0033] Step S201: Obtain the temperature change rate within the preset area where the air conditioner is located, wherein the temperature change rate is negatively correlated with the actual space in which the air conditioner is used and negatively correlated with the actual heat load state of the air conditioner.
[0034] The rate of temperature change refers to the amount of temperature change per unit time, usually expressed in degrees Celsius per second or per minute.
[0035] Among them, the rate of temperature change is negatively correlated with the actual usable space of the air conditioner and negatively correlated with the actual heat load state of the air conditioner. This means that the larger the actual usable space, the lower the rate of temperature change, and the higher the actual heat load state, the lower the rate of temperature change.
[0036] Step S202: Determine whether the upper limit of the compressor's operating frequency needs to be adjusted based on the rate of temperature change. If the upper limit of the compressor's operating frequency needs to be adjusted, lower or raise the upper limit of the compressor's operating frequency so that the energy consumption rate after frequency adjustment is less than the energy consumption rate before frequency adjustment.
[0037] Specifically, if the actual usable space area of the preset area is large and the heat load is heavy (i.e., the temperature change rate is slow), the upper limit of the compressor frequency is increased; if the actual usable space area of the preset area is small and the heat load is light (i.e., the temperature change rate is fast), the upper limit of the compressor frequency is decreased, so as to achieve the purpose of energy saving.
[0038] This embodiment acquires the rate of temperature change within a preset area where the air conditioner is located. Based on this rate of temperature change, it determines whether the upper limit of the air conditioner's compressor operating frequency needs adjustment. If adjustment is necessary, the upper limit is lowered or raised to ensure that the energy consumption rate after frequency adjustment is lower than the energy consumption rate before adjustment. Adjusting the upper limit of the air conditioner's compressor operating frequency based on the rate of temperature change allows the air conditioner to adaptively and dynamically adjust under different space sizes and room heat loads, always maintaining optimal energy efficiency and achieving both energy saving and a comfortable experience.
[0039] In the specific implementation process, step S201 above: obtaining the temperature change rate within the preset area where the air conditioner is located includes: obtaining the initial temperature, the set temperature, the first time taken to adjust from the initial temperature to the set temperature, and the preset time; if the first time taken is less than or equal to the preset time, the ratio of the absolute value of the difference between the initial temperature and the set temperature to the first time taken is determined as the temperature change rate; if the first time taken is longer than the preset time, the ratio of the absolute value of the difference between the initial temperature and the intermediate temperature to the second time taken is determined as the temperature change rate, wherein the intermediate temperature is the temperature obtained at a preset time before changing to the set temperature, and the second time taken is the time taken to change from the initial temperature to the intermediate temperature.
[0040] For example, the preset time is set to 30 minutes; the preset temperature is 30°C; and the initial temperature is 15°C. In the first scenario, if the time taken to rise from 15°C to 30°C is less than or equal to 30 minutes, the ratio of the absolute value of the difference between the initial temperature (15°C) and the preset temperature (30°C) to the first time taken is determined as the temperature change rate. In the second scenario, if the time taken to rise from 15°C to 30°C is 45 minutes (more than 30 minutes), the temperature rise is slow. In this case, an intermediate temperature, such as 25°C, is selected, and the time taken to rise from 15°C to 25°C is determined as the second time taken. Then, the ratio of the absolute value of the difference between the initial temperature and the intermediate temperature to the second time taken is determined as the temperature change rate. This allows for the determination of the temperature change rate.
[0041] Specifically, when the first operating time is less than or equal to a preset time, the ratio of the absolute value of the difference between the initial temperature and the set temperature to the first operating time is determined as the temperature change rate. This includes: when the air conditioner is in cooling mode, the ratio of the difference between the initial temperature and the set temperature to the first operating time is determined as the temperature change rate when the first operating time is less than or equal to the preset time; when the air conditioner is in heating mode, the ratio of the difference between the set temperature and the initial temperature to the first operating time is determined as the temperature change rate when the first operating time is less than or equal to the preset time; when the first operating time is longer than the preset time, the ratio of the absolute value of the difference between the initial temperature and the intermediate temperature to a second operating time is determined as the temperature change rate. This includes: when the air conditioner is in cooling mode, the ratio of the difference between the initial temperature and the intermediate temperature to the second operating time is determined as the temperature change rate; when the air conditioner is in heating mode, the ratio of the difference between the intermediate temperature and the initial temperature to the second operating time is determined as the temperature change rate.
[0042] Specifically, such as Figure 3 As shown, the ambient temperature (5-minute intervals), set temperature, and running time are acquired: the initial temperature is measured once during the initial startup phase and recorded as T0. Then, after the compressor starts, it is measured every 5 minutes for a total of 6 sets, recorded as: T1, T2, T3, T4, T5, and T6. The running time is started from the compressor startup.
[0043] The first time taken is the time T' for the ambient temperature to reach the set temperature;
[0044] Specifically, the rate of temperature change is calculated when the air conditioner is in cooling or heating mode. If the air conditioner is in cooling mode and the air conditioning system cools the environment, the rate of temperature drop needs to be calculated; if the air conditioner is in heating mode and the air conditioning system warms the environment, the rate of temperature rise needs to be calculated.
[0045] This method determines the calculation method for the temperature change rate by comparing the relationship between the first time spent and the preset time; the temperature change rate obtained in this way is used to make the subsequent compressor frequency adjustment of the air conditioner more accurate.
[0046] like Figure 3 As shown, this method determines the temperature change rate of the air conditioner in heating mode and cooling mode based on the relationship between the first time spent and the preset time, resulting in four temperature change rates, including:
[0047] 1) When the air conditioner is in heating mode and the first time taken is longer than the preset time, obtain the rate of temperature change;
[0048] At this point, it indicates that the overall temperature rise rate is particularly slow or that the ambient temperature differs significantly from the set temperature. The ambient temperature can be measured six times. Therefore, for rapid compressor frequency response, the temperature rise calculation should use T6-T0, and the calculation time for the temperature rise rate should be 0.5 hours.
[0049] 2) When the air conditioner is in cooling mode and the first time taken is longer than the preset time, obtain the rate of temperature change;
[0050] At this point, it indicates that the overall temperature drop rate is particularly slow or that the ambient temperature differs significantly from the set temperature. The ambient temperature can be measured six times. Therefore, for the compressor frequency to respond quickly, the temperature drop should be calculated using T0-T6, and the calculation time for the temperature drop rate should be 0.5 hours.
[0051] 3) When the air conditioner is in heating mode and the first time taken is less than the preset time, obtain the rate of temperature change;
[0052] At this point, it indicates that the unit's temperature rise is exceptionally rapid, or the difference between the ambient temperature and the set temperature is very small; the set temperature has been reached before the ambient temperature has completed six temperature checks. Once the ambient temperature reaches the set temperature, according to the air conditioner's program, it will operate at low frequency or shut down, and the ambient temperature will remain constant or gradually rise. Therefore, for accuracy, the temperature rise should be calculated in T at this stage. 设 -T0, the time for calculating the temperature rise rate is T'.
[0053] 4) When the air conditioner is in cooling mode and the first time taken is less than the preset time, obtain the rate of temperature change;
[0054] At this point, it indicates that the unit's temperature drop is exceptionally rapid, or the difference between the ambient temperature and the set temperature is very small; the set temperature has been reached before the ambient temperature has completed six temperature checks. Once the ambient temperature reaches the set temperature, according to the air conditioner's program, it will operate at low frequency or shut down, and the ambient temperature will remain constant or gradually increase. Therefore, for accuracy, the temperature drop should be calculated using T0-T at this stage. 设 The time used to calculate the rate of temperature drop is T'.
[0055] Step S202 of this application determines whether the upper limit of the operating frequency of the air conditioner compressor needs to be adjusted based on the temperature change rate, including: if the temperature change rate is within a preset temperature change rate range, determining that the upper limit of the compressor operating frequency does not need to be adjusted, wherein the preset temperature change rate range corresponding to the cooling operation mode is greater than or equal to the second preset temperature change rate and less than the first preset temperature change rate, and the preset temperature change rate range corresponding to the heating operation mode is greater than or equal to the fourth preset temperature change rate and less than the third preset temperature change rate; if the temperature change rate is not within the preset temperature change rate range, determining that the upper limit of the compressor operating frequency needs to be adjusted.
[0056] This method is as follows Figure 3 As shown, when the air conditioner is in cooling mode, the second preset value is ≤V. 温降 < First preset value; when the air conditioner is in heating mode, fourth preset value ≤ V 温升 <Third preset value; no need to adjust the upper limit of the compressor's operating frequency.
[0057] At this point, it indicates that the temperature drop or rise rate of the entire unit is normal, and that the room area used is consistent with the experimental standard operating conditions or the building load is average, so there is no need to adjust the maximum operating frequency.
[0058] Specifically, when it is necessary to adjust the upper limit of the compressor's operating frequency, the upper limit of the compressor's operating frequency may be lowered or raised, including: when it is necessary to adjust the upper limit of the compressor's operating frequency, and the air conditioner is in cooling mode and the temperature change rate is greater than or equal to a first preset temperature change rate, lowering the preset frequency value of the upper limit of the compressor's operating frequency; when it is necessary to adjust the upper limit of the compressor's operating frequency, and the air conditioner is in cooling mode and the temperature change rate is less than a second preset temperature change rate, raising the preset frequency value of the upper limit of the compressor's operating frequency; when it is necessary to adjust the upper limit of the compressor's operating frequency, and the air conditioner is in heating mode and the temperature change rate is greater than or equal to a third preset temperature change rate, lowering the preset frequency value of the upper limit of the compressor's operating frequency; and when it is necessary to adjust the upper limit of the compressor's operating frequency, and the air conditioner is in cooling mode and the temperature change rate is less than a fourth preset temperature change rate, raising the preset frequency value of the upper limit of the compressor's operating frequency.
[0059] like Figure 3 As shown, when the air conditioner is in cooling mode, V 温升 ≥ First preset value (value range ≥ 20℃ / h); or when the air conditioner is in heating mode, V 温升≥Third preset value (value range ≥20℃ / h); reduce the maximum operating frequency by 6Hz.
[0060] At this point, it indicates that the temperature of the entire unit is dropping or rising very quickly, suggesting that the room area is small or the building load is light. In this case, the cooling or heating capacity provided by the air conditioner can be reduced by lowering the maximum operating frequency. This can reduce the large fluctuations in room temperature and achieve energy saving.
[0061] like Figure 3 As shown, when the air conditioner is in cooling mode, V 温升 <Second preset value (range between 15℃ / h and 20℃ / h); or when the air conditioner is in heating mode, V 温升 <Fourth preset value (value range between 15℃ / h and 20℃ / h); Increase the maximum operating frequency by 6Hz.
[0062] This indicates that the temperature drop or rise of the unit is relatively slow, suggesting that the room area is large or the building load is heavy. In this case, the cooling or heating capacity provided by the air conditioner can be increased by increasing the maximum operating frequency, which can improve the user's comfort.
[0063] Furthermore, after the compressor has been running for a preset period of time based on the reduced or increased upper limit of the operating frequency, or based on the unchanged upper limit of the operating frequency, the method further includes: determining whether the compressor has stopped; if the compressor has not stopped, controlling the compressor to continue running based on the reduced or increased upper limit of the operating frequency, or based on the unchanged upper limit of the operating frequency; if the compressor has stopped, reacquiring the temperature change rate.
[0064] Specifically, there are several reasons why the compressor might stop: If it's shut off via remote control or due to a power outage, it means the customer has used the unit and needs to re-check the compressor frequency upon restarting to avoid reduced comfort due to untimely frequency range updates in response to room load changes. If the compressor stops when the desired temperature is reached, it indicates that even after reducing the frequency by 6Hz, there is still room temperature overshoot, requiring readjustment of the compressor frequency range to improve energy efficiency. If the compressor doesn't stop and continues to run at a low frequency to maintain the room temperature, it means the current compressor frequency range is appropriate. For more details... Figure 3 As shown.
[0065] More specifically, the method also includes: determining whether the change in the heat load state of the air conditioner is due to climate change; if the change in heat load state is due to climate change, adjusting the cooling rate to adjust the operating frequency of the air conditioner's compressor to reduce the air conditioner's energy consumption.
[0066] This method reduces the energy consumption of air conditioners by adjusting the compressor frequency of the air conditioner based on one factor that causes changes in the heat load state of the air conditioner due to climate change.
[0067] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the air conditioning control method of this application will be described in detail below with reference to specific embodiments.
[0068] This embodiment relates to a specific air conditioning control method, such as... Figure 4 As shown, it includes the following steps:
[0069] Step S1: Power on and run the entire machine.
[0070] The rate of temperature drop and the rate of temperature rise should be detected immediately after the machine is powered on.
[0071] Step S2: Obtain the overall machine operating mode.
[0072] Step S3: Determine whether the unit is in cooling or heating mode, and select the appropriate strategy for calculating the rate of temperature change during subsequent operation.
[0073] Step S4: Obtain ambient temperature (5 minutes per set), set temperature and running time.
[0074] Step S5: Calculate the rate of change of ambient temperature. In cooling mode, the air conditioning system cools the environment, so the rate of temperature drop needs to be calculated. In heating mode, the air conditioning system warms the environment, so the rate of temperature rise needs to be calculated. By judging the rate of temperature change, we can determine the room area and load conditions compared to standard laboratory operating conditions, allowing for early intervention. Based on the calculation results, the compressor frequency control can be adjusted.
[0075] Step S6: Determine whether the compressor's upper frequency limit needs to be updated based on the rate of temperature change. Cooling mode: If the temperature drop rate is particularly fast, it indicates that the room area is smaller or the load is lighter compared to standard operating conditions. In this case, the compressor's upper frequency limit can be reduced to achieve energy savings. If the temperature drop rate is moderate, it indicates that the actual room area and load are consistent with standard operating conditions, and the compressor's upper frequency limit does not need adjustment. If the temperature drop rate is small, it indicates that the room area is larger or the load is heavier compared to standard operating conditions. In this case, the compressor's upper frequency limit can be reduced to improve comfort. The heating mode follows the same principle.
[0076] Step S7: Determine if the compressor has stopped. If the compressor has stopped, it may be due to reaching the temperature limit, remote control shutdown, power failure, etc. In this case, the air conditioner's temperature change rate needs to be reassessed, and the compressor's frequency range needs to be updated.
[0077] The above-mentioned air conditioning control method adjusts the upper limit of the compressor's operating frequency according to the rate of temperature change, enabling the air conditioner to adaptively and dynamically adjust under different space areas and room heat loads, always maintaining the best energy efficiency state, achieving energy saving and a comfortable experience.
[0078] This application also provides an air conditioning control device.

[0080] Figure 5 This is a schematic diagram of an air conditioning control device according to an embodiment of this application. Figure 5 As shown, the device includes:
[0081] The first acquisition unit 51 is used to acquire the temperature change rate within the preset area where the air conditioner is located, wherein the temperature change rate is negatively correlated with the actual space in which the air conditioner is used and negatively correlated with the actual heat load state of the air conditioner.
[0082] The rate of temperature change refers to the amount of temperature change per unit time, usually expressed in degrees Celsius per second or per minute.
[0083] Among them, the rate of temperature change is negatively correlated with the actual usable space of the air conditioner and negatively correlated with the actual heat load state of the air conditioner. This means that the larger the actual usable space, the lower the rate of temperature change, and the higher the actual heat load state, the lower the rate of temperature change.
[0084] The adjustment unit 52 is used to determine whether the upper limit of the operating frequency of the air conditioner compressor needs to be adjusted based on the rate of temperature change. If the upper limit of the operating frequency of the compressor needs to be adjusted, the upper limit of the operating frequency of the compressor is lowered or raised so that the energy consumption rate after the frequency adjustment is less than the energy consumption rate before the frequency adjustment.
[0085] Specifically, if the actual usable space area of the preset area is large and the heat load is heavy (i.e., the temperature change rate is slow), the upper limit of the compressor frequency is increased; if the actual usable space area of the preset area is small and the heat load is light (i.e., the temperature change rate is fast), the upper limit of the compressor frequency is decreased, so as to achieve the purpose of energy saving.
[0086] In this embodiment, the first acquisition unit acquires the rate of temperature change within a preset area where the air conditioner is located. The adjustment unit determines whether the upper limit of the compressor's operating frequency needs to be adjusted based on the rate of temperature change. If adjustment is necessary, the upper limit is lowered or raised to ensure that the energy consumption rate after frequency adjustment is lower than the energy consumption rate before adjustment. By adjusting the upper limit of the air conditioner's compressor's operating frequency according to the rate of temperature change, the air conditioner can adaptively and dynamically adjust under different space areas and room heat loads, always maintaining optimal energy efficiency and achieving both energy saving and comfort.
[0087] As an optional solution, the first acquisition unit includes an acquisition module, a first determination module, and a second determination module; the acquisition module is used to acquire an initial temperature, a set temperature, a first time taken to adjust from the initial temperature to the set temperature, and a preset time; the first determination module is used to determine the temperature change rate by the ratio of the absolute value of the difference between the initial temperature and the set temperature to the first time taken when the first time taken is less than or equal to the preset time; the second determination module is used to determine the temperature change rate by the ratio of the absolute value of the difference between the initial temperature and the intermediate temperature to the second time taken when the first time taken is greater than the preset time, wherein the intermediate temperature is the temperature acquired at a preset time before changing to the set temperature, and the second time taken is the time taken to change from the initial temperature to the intermediate temperature.
[0088] For example, the preset time is set to 30 minutes; the preset temperature is 30°C; and the initial temperature is 15°C. In the first scenario, if the time taken to rise from 15°C to 30°C is less than or equal to 30 minutes, the ratio of the absolute value of the difference between the initial temperature (15°C) and the preset temperature (30°C) to the first time taken is determined as the temperature change rate. In the second scenario, if the time taken to rise from 15°C to 30°C is 45 minutes (more than 30 minutes), the temperature rise is slow. In this case, an intermediate temperature, such as 25°C, is selected, and the time taken to rise from 15°C to 25°C is determined as the second time taken. Then, the ratio of the absolute value of the difference between the initial temperature and the intermediate temperature to the second time taken is determined as the temperature change rate. This allows for the determination of the temperature change rate.
[0089] An optional scheme includes a first determining module comprising a first determining submodule, configured to determine the temperature change rate by the ratio of the difference between the initial temperature and the set temperature to the first time duration when the air conditioner is in cooling mode and the first time duration is less than or equal to a preset time duration; and to determine the temperature change rate by the ratio of the difference between the set temperature and the initial temperature to the first time duration when the air conditioner is in heating mode and the first time duration is less than or equal to a preset time duration. The second determining module comprises a second determining submodule, configured to determine the temperature change rate by the ratio of the difference between the initial temperature and the intermediate temperature to the second time duration when the air conditioner is in cooling mode; and to determine the temperature change rate by the ratio of the difference between the intermediate temperature and the initial temperature to the second time duration when the air conditioner is in heating mode.
[0090] Specifically, such as Figure 3 As shown, the ambient temperature (5-minute intervals), set temperature, and running time are acquired: the initial temperature is measured once during the initial startup phase and recorded as T0. Then, after the compressor starts, it is measured every 5 minutes for a total of 6 sets, recorded as: T1, T2, T3, T4, T5, and T6. The running time is started from the compressor startup.
[0091] The first time taken is the time T' for the ambient temperature to reach the set temperature;
[0092] Specifically, the rate of temperature change is calculated when the air conditioner is in cooling or heating mode. If the air conditioner is in cooling mode and the air conditioning system cools the environment, the rate of temperature drop needs to be calculated; if the air conditioner is in heating mode and the air conditioning system warms the environment, the rate of temperature rise needs to be calculated.
[0093] This method determines the calculation method for the temperature change rate by comparing the relationship between the first time spent and the preset time; the temperature change rate obtained in this way is used to make the subsequent compressor frequency adjustment of the air conditioner more accurate.
[0094] like Figure 3 As shown, this method determines the temperature change rate of the air conditioner in heating mode and cooling mode based on the relationship between the first time spent and the preset time, resulting in four temperature change rates, including:
[0095] 1) When the air conditioner is in heating mode and the first time taken is longer than the preset time, obtain the rate of temperature change;
[0096] At this point, it indicates that the overall temperature rise rate is particularly slow or that the ambient temperature differs significantly from the set temperature. The ambient temperature can be measured six times. Therefore, for rapid compressor frequency response, the temperature rise calculation should use T6-T0, and the calculation time for the temperature rise rate should be 0.5 hours.
[0097] 2) When the air conditioner is in cooling mode and the first time taken is longer than the preset time, obtain the rate of temperature change;
[0098] At this point, it indicates that the overall temperature drop rate is particularly slow or that the ambient temperature differs significantly from the set temperature. The ambient temperature can be measured six times. Therefore, for the compressor frequency to respond quickly, the temperature drop should be calculated using T0-T6, and the calculation time for the temperature drop rate should be 0.5 hours.
[0099] 3) When the air conditioner is in heating mode and the first time taken is less than the preset time, obtain the rate of temperature change;
[0100] At this point, it indicates that the unit's temperature rise is exceptionally rapid, or the difference between the ambient temperature and the set temperature is very small; the set temperature has been reached before the ambient temperature has completed six temperature checks. Once the ambient temperature reaches the set temperature, according to the air conditioner's program, it will operate at low frequency or shut down, and the ambient temperature will remain constant or gradually rise. Therefore, for accuracy, the temperature rise should be calculated in T at this stage. 设 -T0, the time for calculating the temperature rise rate is T'.
[0101] 4) When the air conditioner is in cooling mode and the first time taken is less than the preset time, obtain the rate of temperature change;
[0102] At this point, it indicates that the unit's temperature drop is exceptionally rapid, or the difference between the ambient temperature and the set temperature is very small; the set temperature has been reached before the ambient temperature has completed six temperature checks. Once the ambient temperature reaches the set temperature, according to the air conditioner's program, it will operate at low frequency or shut down, and the ambient temperature will remain constant or gradually increase. Therefore, for accuracy, the temperature drop should be calculated using T0-T at this stage. 设 The time used to calculate the rate of temperature drop is T'.
[0103] In one alternative approach, the adjustment unit includes a third determining module and a fourth determining module;
[0104] The third determining module is used to determine that, when the rate of temperature change is within a preset range, it is not necessary to adjust the upper limit of the compressor's operating frequency. The preset range of the rate of temperature change corresponding to the cooling operation mode is greater than or equal to the second preset rate of temperature change and less than the first preset rate of temperature change, and the preset range of the rate of temperature change corresponding to the heating operation mode is greater than or equal to the fourth preset rate of temperature change and less than the third preset rate of temperature change. The fourth determining module is used to determine that, when the rate of temperature change is not within a preset range, it is necessary to adjust the upper limit of the compressor's operating frequency.
[0105] This method is as follows Figure 3 As shown, when the air conditioner is in cooling mode, the second preset value is ≤V. 温降 < First preset value; when the air conditioner is in heating mode, fourth preset value ≤ V 温升 <Third preset value; no need to adjust the upper limit of the compressor's operating frequency.
[0106] At this point, it indicates that the temperature drop or rise rate of the entire unit is normal, and that the room area used is consistent with the experimental standard operating conditions or the building load is average, so there is no need to adjust the maximum operating frequency.
[0107] In one alternative approach, the fourth determining module includes a first lowering submodule, a first raising submodule, a second lowering submodule, and a second raising submodule.
[0108] The first reduction submodule is used to reduce the preset upper limit frequency value of the compressor's operating frequency when it is necessary to adjust the upper limit of the compressor's operating frequency, the air conditioner's operating mode is cooling mode, and the temperature change rate is greater than or equal to the first preset temperature change rate. The first increase submodule is used to increase the preset upper limit frequency value of the compressor's operating frequency when it is necessary to adjust the upper limit of the compressor's operating frequency, the air conditioner's operating mode is cooling mode, and the temperature change rate is less than the second preset temperature change rate. The second reduction submodule is used to reduce the preset upper limit frequency value of the compressor's operating frequency when it is necessary to adjust the upper limit of the compressor's operating frequency, the air conditioner's operating mode is heating mode, and the temperature change rate is greater than or equal to the third preset temperature change rate. The second increase submodule is used to increase the preset upper limit frequency value of the compressor's operating frequency when it is necessary to adjust the upper limit of the compressor's operating frequency, the air conditioner's operating mode is cooling mode, and the temperature change rate is less than the fourth preset temperature change rate.
[0109] like Figure 3 As shown, when the air conditioner is in cooling mode, V 温升≥ First preset value (value range ≥ 20℃ / h); or when the air conditioner is in heating mode, V 温升 ≥Third preset value (value range ≥20℃ / h); reduce the maximum operating frequency by 6Hz.
[0110] At this point, it indicates that the temperature of the entire unit is dropping or rising very quickly, suggesting that the room area is small or the building load is light. In this case, the cooling or heating capacity provided by the air conditioner can be reduced by lowering the maximum operating frequency. This can reduce the large fluctuations in room temperature and achieve energy saving.
[0111] like Figure 3 As shown, when the air conditioner is in cooling mode, V 温升 <Second preset value (range between 15℃ / h and 20℃ / h); or when the air conditioner is in heating mode, V 温升 <Fourth preset value (value range between 15℃ / h and 20℃ / h); Increase the maximum operating frequency by 6Hz.
[0112] This indicates that the temperature drop or rise of the unit is relatively slow, suggesting that the room area is large or the building load is heavy. In this case, the cooling or heating capacity provided by the air conditioner can be increased by increasing the maximum operating frequency, which can improve the user's comfort.
[0113] In one alternative embodiment, the device further includes a determining unit, a controlling unit, and a second acquiring unit;
[0114] The determining unit is used to determine whether the compressor should stop after the compressor has been running for a preset period of time based on the reduced or increased upper limit of the operating frequency, or based on the unchanged upper limit of the operating frequency; the controlling unit is used to control the compressor to continue running based on the reduced or increased upper limit of the operating frequency, or based on the unchanged upper limit of the operating frequency, if the compressor has not stopped; the second acquiring unit is used to reacquire the temperature change rate if the compressor has stopped.
[0115] Specifically, there are several reasons why the compressor might stop: If it's shut off via remote control or due to a power outage, it means the customer has used the unit and needs to re-check the compressor frequency upon restarting to avoid reduced comfort due to untimely frequency range updates in response to room load changes. If the compressor stops when the desired temperature is reached, it indicates that even after reducing the frequency by 6Hz, there is still room temperature overshoot, requiring readjustment of the compressor frequency range to improve energy efficiency. If the compressor doesn't stop and continues to run at a low frequency to maintain the room temperature, it means the current compressor frequency range is appropriate. For more details...

[0116] The air conditioning control device includes a processor and a memory. The aforementioned first acquisition unit, adjustment unit, etc., are all stored as program units in the memory, and the processor executes the aforementioned program units stored in the memory to achieve the corresponding functions. All of the above modules are located in the same processor; alternatively, the above modules may be located in different processors in any combination.
[0117] This device reduces the energy consumption of the air conditioner by adjusting the compressor frequency based on a factor that causes changes in the heat load state of the air conditioner due to climate change, thus making the solution more complete during implementation.
[0118] The processor contains a kernel, which retrieves the corresponding program units from memory. One or more kernels can be configured; adjusting kernel parameters can address the issue of poor compatibility between the air conditioner's operating status and the actual usage environment.
[0119] The memory may include non-permanent memory in computer-readable media, such as random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.
