Description

Technical Field

[0001] This application relates to the field of air conditioning control technology, and in particular, to an air conditioning control method, device, system and air conditioner. Background Technology

[0002] An air conditioner, or air conditioner, is a device that uses artificial means to partially or completely regulate the temperature, humidity, airflow, and cleanliness of air in a closed space, so that the air parameters of the target environment meet the requirements. It generally includes cold and heat source equipment, cold and heat medium system, terminal devices, and other auxiliary equipment, mainly including water pumps, fans, and piping systems.

[0003] Air conditioners can be classified into two types according to their structure: modular and split-type; and according to their function: cooling-only air conditioners and cooling-heating air conditioners. In the 21st century, China's household air conditioning industry has gradually matured, and air conditioning products have become an essential appliance in people's homes.

[0004] However, traditional air conditioners only consider the user experience under stable operation. If the user forgets to turn on the air conditioner in advance, it will still adjust to stable operation when first turned on, resulting in a poor user experience. Furthermore, when users need rapid cooling / heating, they often stand near the air outlet, requiring the air conditioner to quickly cool / heat their body temperature. And when the user's body temperature is close to the set temperature, even if the air conditioner's output of cooling / heating is slightly lower, the user's own heat dissipation can still ensure comfort. However, existing air conditioners are prone to overshooting when rapidly cooling / heating, causing overheating or overcooling, reducing air comfort and affecting the user experience. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, this application provides an air conditioning control method, device, system and air conditioner to solve the problem that when the existing air conditioner performs rapid cooling / heating, it is easy to cause overshoot, resulting in overheating or overcooling, reducing air comfort and affecting user experience.

[0015] The delay duration is determined based on the frequency difference; the larger the frequency difference, the longer the delay duration.

[0016] As a preferred implementation of this application, it also includes:

[0017] The first preset temperature difference is determined based on the user-set temperature and the air conditioner's operating mode;

[0018] The operating modes include rapid cooling mode and rapid heating mode;

[0019] In the rapid cooling mode, the lower the user-set temperature, the smaller the first preset temperature difference; in the rapid heating mode, the higher the user-set temperature, the smaller the first preset temperature difference.

[0020] As a preferred implementation of this application, it also includes:

[0021] Upon receiving a user's command for rapid cooling or rapid heating, the system enters the rapid cooling mode or rapid heating mode.

[0022] And / or; after the air conditioner is turned on, acquire the target parameters, and determine whether to enter the rapid cooling mode or the rapid heating mode based on the target parameters.

[0023] In a preferred implementation of this application, the target parameters include indoor temperature and user-set temperature, and the step of determining whether to enter the rapid cooling module or rapid heating mode based on the target parameters includes:

[0024] When the absolute value of the temperature difference between the indoor temperature and the user-set temperature is greater than or equal to the second preset temperature difference, the system enters the rapid cooling mode or the rapid heating mode.

[0025] When the absolute value of the temperature difference between the indoor temperature and the user-set temperature is less than the second preset temperature difference, the rapid cooling mode or the rapid heating mode will not be entered.

[0026] Wherein, the second preset temperature difference is greater than the first preset temperature difference.

[0027] In a preferred implementation of this application, the target parameter includes the user's body surface temperature, and the step of determining whether to enter the rapid cooling module or rapid heating mode based on the target parameter includes:

[0028] When the difference between the user's body surface temperature and the preset body surface temperature is greater than or equal to the third preset temperature difference, the system enters the rapid cooling mode or the rapid heating mode.

[0029] When the difference between the user's body surface temperature and the preset body surface temperature is less than the third preset temperature difference, the rapid cooling mode or the rapid heating mode will not be entered.

[0030] Secondly, an air conditioning control device is provided, comprising:

[0038] Beneficial effects:

[0039] This application provides an air conditioning control method, device, system, and air conditioner. The air conditioning control method includes: when the air conditioner enters a rapid cooling mode or a rapid heating mode, controlling the air conditioner's compressor to operate at its maximum frequency to maximize the cooling or heating output, thereby quickly reaching the user-set indoor temperature. If the indoor temperature has not reached the user-set temperature, and the absolute value of the temperature difference between the indoor temperature and the user-set temperature is less than or equal to a first preset temperature difference, even if the compressor stops, the indoor temperature can still reach the user-set temperature. However, directly stopping the compressor can easily lead to frequent compressor start-stop cycles. Therefore, this application controls the compressor to operate from its maximum frequency to its minimum frequency. This ensures that the indoor temperature reaches the user-set temperature, and even after the indoor temperature reaches the user-set temperature, the compressor continues to operate at its minimum frequency without stopping, avoiding frequent compressor start-stop cycles. Finally, after a delay, the rapid cooling mode or rapid heating mode exits, and the air conditioner is controlled normally for cooling or heating. This ensures that the air conditioner can quickly adjust the indoor temperature to the user-set temperature while avoiding overshoot and frequent compressor start-stop cycles, thus improving the user experience.

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] When air conditioners perform rapid cooling or heating, they often shut off the compressor only after the indoor temperature reaches the user's set temperature. Some control schemes, to avoid frequent compressor start-stop cycles, even shut off the compressor only after the indoor temperature exceeds the user's set temperature. However, because the compressor frequency is often at its maximum during rapid cooling or heating, adjusting only when the indoor temperature reaches or exceeds the user's set temperature can cause further temperature fluctuations, leading to overshoot, reduced air comfort, and a negative impact on user experience. Conversely, shutting off the compressor before the indoor temperature reaches the user's set temperature can easily cause frequent compressor start-stop cycles, shortening the compressor's lifespan. Furthermore, shutting off the compressor too early can prevent the indoor temperature from reaching the set temperature, thus failing to meet usage requirements.

[0050] To solve the above technical problems, refer to Figure 1 This application provides an air conditioning control method, including:

[0051] S11: When the air conditioner enters rapid cooling mode or rapid heating mode, control the air conditioner's compressor to run at maximum frequency. Additionally, control the indoor and outdoor fan speeds to maximum to quickly reach the user-set indoor temperature.

[0052] In one embodiment, upon receiving a user's command for rapid cooling or rapid heating, the system enters the rapid cooling mode or rapid heating mode. That is, the air conditioner has a dedicated selection of rapid cooling and rapid heating modes, which the user can manually select via remote control / control panel / APP, etc.

[0053] In another embodiment, after the air conditioner is turned on, target parameters are acquired, and a determination is made based on the target parameters whether to enter a rapid cooling mode or a rapid heating mode. That is, in this embodiment, the determination of whether to enter a rapid cooling mode or a rapid heating mode can also be automatically made based on relevant target parameters.

[0054] In some examples, such as Figure 2 As shown, the target parameters include indoor temperature and user-set temperature. The step of determining whether to enter the rapid cooling module or rapid heating mode based on the target parameters includes:

[0055] When the absolute value of the temperature difference between the indoor temperature and the user-set temperature is greater than or equal to a second preset temperature difference, the system enters the rapid cooling mode or the rapid heating mode. When the absolute value of the temperature difference between the indoor temperature and the user-set temperature is greater than or equal to the second preset temperature difference, it indicates a significant difference between the indoor temperature and the user-set temperature. Under conventional control methods, the compressor would operate at a preset frequency (less than the maximum frequency), resulting in slow cooling or heating. Therefore, the improvement of this application is that it directly enters the rapid cooling or rapid heating mode in this situation, facilitating a quick attainment of the user-set indoor temperature. It is understood that the user-set temperature is the desired indoor temperature, typically set via remote control / control panel.

[0056] When the absolute value of the temperature difference between the indoor temperature and the user-set temperature is less than the second preset temperature difference, the rapid cooling mode or the rapid heating mode will not be entered.

[0057] Wherein, the second preset temperature difference is greater than the first preset temperature difference.

[0058] In other examples, such as Figure 3 As shown, the target parameter includes the user's body surface temperature. The step of determining whether to enter the rapid cooling module or rapid heating mode based on the target parameter includes:

[0059] When the difference between the user's body surface temperature and the preset body surface temperature is greater than or equal to a third preset temperature difference, the system enters the rapid cooling mode or the rapid heating mode. The preset body surface temperature is either a normal human body temperature obtained based on big data or a normal temperature set by the user. When the difference between the user's body surface temperature and the preset body surface temperature is greater than or equal to the third preset temperature difference, it indicates that the user's body surface temperature differs significantly from the normal value, requiring rapid cooling or rapid heating.

[0060] When the difference between the user's body surface temperature and the preset body surface temperature is less than the third preset temperature difference, the rapid cooling mode or the rapid heating mode will not be entered.

[0061] S12: When the indoor temperature does not reach the user-set temperature, and the absolute value of the temperature difference between the indoor temperature and the user-set temperature is less than or equal to the first preset temperature difference, the compressor is controlled to change from the maximum frequency to the minimum frequency, and exits the rapid cooling mode or the rapid heating mode after a delay.

[0062] The maximum and minimum frequencies are preset values. Different models and under different conditions correspond to different maximum and / or minimum frequencies. When shutting down directly from the maximum frequency, the compressor stops immediately. However, when adjusting from the maximum to the minimum frequency, the compressor uses a stepped frequency reduction scheme. That is, multiple intermediate frequencies are set between the maximum and minimum frequencies (e.g., frequencies a, b, and c from high to low). Then, it reduces from the maximum frequency to frequency a and runs for a period of time, then reduces to frequency b and runs for a period of time, then reduces to frequency c and runs for a period of time before finally reducing to the minimum frequency. The reason for this setting is that since the difference between the maximum and minimum frequencies is large, directly reducing the frequency would cause compressor failure.

[0063] In one embodiment, the first preset temperature difference is a preset fixed value. However, when using a fixed value, the temperature changes differently due to different external environments (taking refrigeration as an example, when the outside temperature is high, the indoor temperature drops less in the same amount of time under the same cooling capacity, while when the outside temperature is low, the indoor temperature drops more in the same amount of time under the same cooling capacity). Therefore, when the outside temperature is high, the indoor temperature may not reach the user-set temperature, while when the outside temperature is low, the indoor temperature may exceed the user-set temperature (i.e., overshoot).

[0064] Therefore, in another embodiment of this application, the current temperature change rate is obtained; the current temperature change rate = (current temperature - previous temperature) / (current time - previous time).

[0065] The product of the current temperature change rate and the delay time is used as the first preset temperature difference.

[0066] The delay duration is related to the output capacity and capacity adjustment speed of the equipment. Generally speaking, the higher the capacity of the equipment, the longer the delay duration, and the slower the capacity adjustment speed of the equipment, the shorter the delay duration.

[0067] Therefore, in some embodiments, an air conditioner uses a fixed value based on experiments or a preset delay duration. However, in actual use, the output capacity of the same device can vary under different operating conditions.

[0068] Therefore, in order to achieve a more accurate adjustment effect, in another embodiment of this application, the delay duration is determined based on the actual maximum and minimum frequencies. For example:

[0069] Calculate the frequency difference between the actual maximum frequency and the minimum frequency;

[0070] The delay duration is determined based on the frequency difference; the larger the frequency difference, the longer the delay duration.

[0071] Because under certain operating conditions, the actual frequency of the compressor cannot reach the preset maximum frequency, the delay duration is determined by the actual maximum frequency during actual control.

[0072] In addition, it also includes:

[0073] The first preset temperature difference is determined based on the user-set temperature and the air conditioner's operating mode;

[0074] The operating modes include rapid cooling mode and rapid heating mode;

[0075] In the rapid cooling mode, the lower the user-set temperature, the smaller the first preset temperature difference; in the rapid heating mode, the higher the user-set temperature, the smaller the first preset temperature difference.

[0076] It should be noted that any process or method description in the flowchart or otherwise described herein can be understood as representing a module, segment, or portion of code comprising one or more executable instructions for implementing a particular logical function or process, and the scope of the preferred embodiments of this application includes additional implementations in which functions may be performed not in the order shown or discussed, including substantially simultaneously or in reverse order according to the functions involved, as should be understood by those skilled in the art to which the embodiments of this application pertain.

[0077] Furthermore, in the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0078] The control method provided in this application controls the air conditioner's compressor to operate at its maximum frequency when the air conditioner enters rapid cooling or rapid heating mode. This maximizes the air conditioner's cooling or heating output, allowing the indoor temperature to quickly reach the user-set temperature. If the indoor temperature has not reached the user-set temperature, and the absolute value of the temperature difference between the indoor temperature and the user-set temperature is less than or equal to a first preset temperature difference, even if the compressor stops, the indoor temperature can still reach the user-set temperature. However, directly stopping the compressor can easily lead to frequent compressor start-stop cycles. Therefore, this application's solution controls the compressor to operate at its minimum frequency instead of its maximum frequency. This ensures that the indoor temperature reaches the user-set temperature, and even after the indoor temperature reaches the user-set temperature, the compressor continues to operate at its minimum frequency without needing to stop, thus avoiding frequent compressor start-stop cycles. Finally, after a delay, the rapid cooling or rapid heating mode exits, and the air conditioner is controlled normally for cooling or heating. This ensures that the air conditioner can quickly adjust the indoor temperature to the user-set temperature while avoiding overshoot and frequent compressor start-stop cycles, thereby improving the user experience.

[0079] To more clearly illustrate the proposed solution, a specific implementation method is provided below.

[0080] This application is applicable to various air conditioning systems, providing users with a one-button quick cooling (i.e., rapid cooling) / one-button quick heating (i.e., rapid heating) mode option. It can quickly lower / raise the room temperature to the desired temperature when the user needs it. At the same time, when the temperature is about to drop / raise to the target temperature, the residual heat of the two heat exchangers is used to ensure the output of cooling / heating capacity and ensure that the compressor receives sufficient cooling. This can avoid over-adjustment due to excessive change rate and ensure that the compressor receives sufficient cooling after high load operation.

[0081] like Figure 4 As shown, when the user turns on the air conditioner and sets the quick-cooling mode, the air conditioner will automatically increase the compressor frequency to the maximum allowable frequency to ensure maximum cooling output. Simultaneously, it will operate the indoor and outdoor fans at maximum speed to ensure the highest heat exchange efficiency. When the detected indoor temperature T2 - indoor temperature change rate A1 × preset delay t1 < user-set temperature T1, it enters the energy-saving transition phase, adjusting the compressor frequency to the minimum allowable frequency to avoid power consumption during start-up and shutdown while ensuring sufficient compressor cooling. This also reduces the temperature change rate and prevents over-adjustment. After the preset delay t1, the room temperature has essentially reached the target temperature, and the system automatically exits the quick-cooling mode, adjusting the compressor frequency and indoor / outdoor fan speeds according to normal cooling settings until power is cut off or the system switches to another mode.

[0082] The system continuously monitors the inner ring temperature. The ratio of the difference between two consecutive inner ring temperatures measured to the monitoring interval is the indoor temperature change rate A1. (For example, if the system monitoring interval is 0.5 seconds, the first inner ring temperature detected is 28℃, and the second inner ring temperature detected is 27℃, then A1 = (27-28) / 0.5 = -2℃ / s). Furthermore, the preset delay t1 is related to the equipment's output capacity and capacity adjustment speed. Generally, the higher the equipment's capacity, the longer the delay; conversely, the slower the capacity adjustment speed, the shorter the preset delay.

[0083] like Figure 5 As shown, when the user turns on the air conditioner and sets the quick-heating mode, the air conditioner will automatically increase the compressor frequency to the maximum allowable frequency to ensure maximum cooling output. Simultaneously, it will operate the indoor and outdoor fans at maximum speed to ensure the highest heat exchange efficiency. When the detected indoor temperature T2 + indoor temperature change rate A1 × preset delay t1 > user-set temperature T1, it enters the energy-saving transition phase. The compressor frequency is adjusted to the minimum allowable frequency to avoid power consumption during start-up and shutdown, while ensuring sufficient compressor cooling and reducing the temperature change rate to prevent over-adjustment. After the preset delay t1, the room temperature has essentially reached the target temperature, and the system automatically exits the quick-heating mode, adjusting the compressor frequency and indoor / outdoor fan speeds according to normal heating settings until power is cut off or the system switches to another mode.

[0084] When users activate the rapid cooling / heating mode, it's often because they've just returned from an overheated / cold environment. At this time, users are less sensitive to temperature changes and expect their body temperature to quickly return to normal. The air conditioner's maximum power output can quickly cool / heat the room. When the ambient temperature is close to the target temperature, the user's body temperature is also close to normal. At this time, the user is more sensitive to ambient temperature. The compressor frequency can be reduced to a minimum to prevent damage from prolonged high-load operation and to avoid energy consumption from start-stop cycles. At the same time, the temperature change rate is significantly reduced to avoid over-adjustment. Based on the temperature changes during this period, it can quickly switch to the regular cooling / heating mode and start working immediately.

[0085] The air conditioner in this embodiment provides a one-button start-up function for rapid cooling and heating, eliminating the need for manual temperature setting for slow adjustment. This solves the problem of cumbersome operation associated with conventional air conditioning, which requires manually setting the temperature to the lowest point to force maximum cooling capacity and then manually setting it to the highest point to force maximum heating capacity. By automatically switching back to the normal cooling and heating mode, it avoids prolonged overload operation and excessive temperature deviation, preventing the need for manual resetting to the optimal temperature after manually setting it to the lowest or highest point, which could lead to overheating or overcooling. Furthermore, by switching back to the normal cooling and heating mode in advance, it utilizes the natural heat dissipation time as the user's body temperature stabilizes to restore the air conditioner's cooling and heating performance, avoiding over-adjustment and addressing the issue of significant temperature fluctuations and inability to stabilize quickly when manually adjusting the temperature.

[0086] Based on the same inventive concept, such as Figure 6 As shown, this application provides an air conditioning control device 60, including:

[0087] The maximum frequency operation module 61 is used to control the air conditioner's compressor to operate at maximum frequency when the air conditioner enters rapid cooling mode or rapid heating mode. Additionally, it controls the indoor and outdoor fan speeds to be adjusted to maximum to quickly reach the user-set indoor temperature.

[0088] In one embodiment, upon receiving a user's command for rapid cooling or rapid heating, the system enters the rapid cooling mode or rapid heating mode. That is, the air conditioner has a dedicated selection of rapid cooling and rapid heating modes, which the user can manually select via remote control / control panel / APP, etc.

[0089] In another embodiment, after the air conditioner is turned on, target parameters are acquired, and a determination is made based on the target parameters whether to enter a rapid cooling mode or a rapid heating mode. That is, in this embodiment, the determination of whether to enter a rapid cooling mode or a rapid heating mode can also be automatically made based on relevant target parameters.

[0090] In some examples, such as Figure 2 As shown, the target parameters include indoor temperature and user-set temperature. The step of determining whether to enter the rapid cooling module or rapid heating mode based on the target parameters includes:

[0091] When the absolute value of the temperature difference between the indoor temperature and the user-set temperature is greater than or equal to a second preset temperature difference, the system enters the rapid cooling mode or the rapid heating mode. When the absolute value of the temperature difference between the indoor temperature and the user-set temperature is greater than or equal to the second preset temperature difference, it indicates a significant difference between the indoor temperature and the user-set temperature. Under conventional control methods, the compressor would operate at a preset frequency (less than the maximum frequency), resulting in slow cooling or heating. Therefore, the improvement of this application is that it directly enters the rapid cooling or rapid heating mode in this situation, facilitating a quick attainment of the user-set indoor temperature. It is understood that the user-set temperature is the desired indoor temperature, typically set via remote control / control panel.

[0092] When the absolute value of the temperature difference between the indoor temperature and the user-set temperature is less than the second preset temperature difference, the rapid cooling mode or the rapid heating mode will not be entered.

[0093] Wherein, the second preset temperature difference is greater than the first preset temperature difference.

[0094] In other examples, such as Figure 3As shown, the target parameter includes the user's body surface temperature. The step of determining whether to enter the rapid cooling module or rapid heating mode based on the target parameter includes:

[0095] When the difference between the user's body surface temperature and the preset body surface temperature is greater than or equal to a third preset temperature difference, the system enters the rapid cooling mode or the rapid heating mode. The preset body surface temperature is either a normal human body temperature obtained based on big data or a normal temperature set by the user. When the difference between the user's body surface temperature and the preset body surface temperature is greater than or equal to the third preset temperature difference, it indicates that the user's body surface temperature differs significantly from the normal value, requiring rapid cooling or rapid heating.

[0096] When the difference between the user's body surface temperature and the preset body surface temperature is less than the third preset temperature difference, the rapid cooling mode or the rapid heating mode will not be entered.

[0097] The minimum frequency operation module 62 is used to control the compressor to change from the maximum frequency to the minimum frequency when the indoor temperature has not reached the user-set temperature and the absolute value of the temperature difference between the indoor temperature and the user-set temperature is less than or equal to the first preset temperature difference, and exit the rapid cooling mode or the rapid heating mode after a delay.

[0098] The maximum and minimum frequencies are preset values. Different models and under different conditions correspond to different maximum and / or minimum frequencies.

[0099] In one embodiment, the first preset temperature difference is a preset fixed value. However, when using a fixed value, the temperature changes differently due to different external environments (taking refrigeration as an example, when the outside temperature is high, the indoor temperature drops less in the same amount of time under the same cooling capacity, while when the outside temperature is low, the indoor temperature drops more in the same amount of time under the same cooling capacity). Therefore, when the outside temperature is high, the indoor temperature may not reach the user-set temperature, while when the outside temperature is low, the indoor temperature may exceed the user-set temperature (i.e., overshoot).

[0100] Therefore, in another embodiment of this application, the current temperature change rate is obtained; the current temperature change rate = (current temperature - previous temperature) / (current time - previous time).

[0101] The product of the current temperature change rate and the delay time is used as the first preset temperature difference.

[0102] The delay duration is related to the output capacity and capacity adjustment speed of the equipment. Generally speaking, the higher the capacity of the equipment, the longer the delay duration, and the slower the capacity adjustment speed of the equipment, the shorter the delay duration.

[0103] Therefore, in some embodiments, an air conditioner uses a fixed value based on experiments or a preset delay duration. However, in actual use, the output capacity of the same device can vary under different operating conditions.

[0104] Therefore, in order to achieve a more accurate adjustment effect, in another embodiment of this application, the delay duration is determined based on the actual maximum and minimum frequencies. For example:

[0105] Calculate the frequency difference between the actual maximum frequency and the minimum frequency;

[0106] The delay duration is determined based on the frequency difference; the larger the frequency difference, the longer the delay duration.

[0107] Because under certain operating conditions, the actual frequency of the compressor cannot reach the preset maximum frequency, the delay duration is determined by the actual maximum frequency during actual control.

[0108] In addition, it also includes:

[0109] The first preset temperature difference is determined based on the user-set temperature and the air conditioner's operating mode;

[0110] The operating modes include rapid cooling mode and rapid heating mode;

[0111] In the rapid cooling mode, the lower the user-set temperature, the smaller the first preset temperature difference; in the rapid heating mode, the higher the user-set temperature, the smaller the first preset temperature difference.

[0112] The air conditioning control device provided in this application controls the air conditioner's compressor to operate at its maximum frequency when the air conditioner enters rapid cooling or rapid heating mode. This maximizes the air conditioner's cooling or heating output, allowing the indoor temperature to quickly reach the user-set temperature. If the indoor temperature has not reached the user-set temperature, and the absolute value of the temperature difference between the indoor temperature and the user-set temperature is less than or equal to a first preset temperature difference, even if the compressor stops, the indoor temperature can still reach the user-set temperature. However, directly stopping the compressor can easily lead to frequent compressor start-stop cycles. Therefore, this application's solution controls the compressor to operate at its minimum frequency instead of its maximum frequency. This ensures that the indoor temperature reaches the user-set temperature, and even after the indoor temperature reaches the user-set temperature, the compressor continues to operate at its minimum frequency without needing to stop, avoiding frequent compressor start-stop cycles. Finally, after a delay, the rapid cooling or rapid heating mode exits, and the air conditioner is controlled normally for cooling or heating. This ensures that the air conditioner can quickly adjust the indoor temperature to the user-set temperature while avoiding overshoot and frequent compressor start-stop cycles, thus improving the user experience.

[0113] Based on the same inventive concept, such as Figure 7 As shown, this application provides an air conditioning control system 70, including:

[0114] At least one processor 71 and at least one memory 72;

[0115] The memory stores the executable instructions of the processor;

[0116] The processor is configured to perform any of the above-described air conditioning control methods.

[0117] The air conditioning control system provided in this application stores executable instructions of the processor in a memory. When these instructions are executed, the processor controls the air conditioner's compressor to run at its maximum frequency when the air conditioner enters a rapid cooling or rapid heating mode. This maximizes the cooling or heating output of the air conditioner, allowing the indoor temperature to quickly reach the user-set temperature. If the indoor temperature has not reached the user-set temperature, and the absolute value of the temperature difference between the indoor temperature and the user-set temperature is less than or equal to a first preset temperature difference, even if the compressor stops, the indoor temperature can still reach the user-set temperature. However, directly stopping the compressor can easily lead to frequent compressor start-stop cycles. Therefore, this application's solution controls the compressor to run at its minimum frequency instead of its maximum frequency. This ensures that the indoor temperature reaches the user-set temperature, and even after the indoor temperature reaches the user-set temperature, the compressor continues to run at its minimum frequency without needing to stop, avoiding frequent compressor start-stop cycles. Finally, after a delay, the system exits the rapid cooling or rapid heating mode and resumes normal cooling or heating control. This ensures that the air conditioner can quickly adjust the indoor temperature to the user-set temperature while avoiding overshoot and frequent compressor start-stop cycles, thus improving the user experience.

[0123] The computer-readable storage medium provided in this application embodiment stores a computer program, which, when executed by a processor, implements the steps of the air conditioning control method provided in any of the above embodiments. Thus, when the air conditioner enters a rapid cooling mode or a rapid heating mode, the compressor is controlled to operate at its maximum frequency, maximizing the cooling or heating output of the air conditioner and quickly bringing the indoor temperature to the user-set temperature. If the indoor temperature has not reached the user-set temperature, and the absolute value of the temperature difference between the indoor temperature and the user-set temperature is less than or equal to a first preset temperature difference, even if the compressor stops, the indoor temperature can still be guaranteed to reach the user-set temperature. However, directly stopping the compressor can easily lead to frequent compressor start-stop cycles. Therefore, this application solution controls the compressor to operate from its maximum frequency to its minimum frequency. This ensures that the indoor temperature reaches the user-set temperature, and even after the indoor temperature reaches the user-set temperature, the compressor continues to operate at its minimum frequency without needing to stop, avoiding frequent compressor start-stop cycles. Finally, after a delay, the rapid cooling mode or rapid heating mode exits, and normal cooling or heating is resumed. This ensures that the air conditioner can quickly adjust the indoor temperature to the user-set temperature while avoiding overshoot and frequent compressor start-stop cycles, thus improving the user experience.

[0124] Based on the same inventive concept, this application also provides an air conditioner that applies the air conditioner control method provided in any of the above embodiments.

[0125] The air conditioner provided in this application embodiment, by applying the air conditioner control method provided in any of the above embodiments, can control the air conditioner compressor to run at maximum frequency when the air conditioner enters rapid cooling mode or rapid heating mode, so as to maximize the cooling or heating output of the air conditioner and quickly bring the indoor temperature to the user-set temperature. When the indoor temperature has not reached the user-set temperature, and the absolute value of the temperature difference between the indoor temperature and the user-set temperature is less than or equal to a first preset temperature difference, even if the compressor stops, the indoor temperature can still be guaranteed to reach the user-set temperature. However, directly stopping the compressor can easily lead to frequent compressor start-stop. Therefore, the solution of this application controls the compressor to run from maximum frequency to minimum frequency. This can ensure that the indoor temperature can reach the user-set temperature, and after the indoor temperature reaches the user-set temperature, the compressor can continue to run at minimum frequency without stopping, avoiding frequent compressor start-stop. Finally, after a delay, the rapid cooling mode or rapid heating mode is exited, and the air conditioner is controlled according to normal cooling or heating. This ensures that the air conditioner can quickly adjust the indoor temperature to the user-set temperature, while avoiding overshoot and frequent compressor start-stop, thereby improving the user experience.
