Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliances, and particularly to a control method, a control device, and an air conditioner for an air conditioner. Background Art

[0002] In the related art, in the process that the ambient temperature approaches the set temperature, the traditional air conditioner control system often keeps the frequency of the compressor and the rotation speeds of the indoor and outdoor fans unchanged. This approach has the following disadvantages: (1) inaccurate temperature control: When the ambient temperature approaches the target temperature set by the user, due to the lack of corresponding adjustment of the compressor and fan speeds, the indoor temperature may fluctuate and the ideal constant temperature effect cannot be achieved. For example, when approaching the set temperature, the air conditioner system may still operate at full power, resulting in the temperature being too low or too high, affecting the user experience. (2) energy waste: When the temperature approaches the set value, the full-power operation of the system not only causes energy waste but also may lead to an increase in electricity costs. Especially during nighttime or low-load periods, this excessive energy consumption is particularly obvious. (3) low system efficiency: Since the compressor and fan do not slow down their operating speeds when approaching the target temperature, this leads to a reduction in system efficiency because such high cooling or heating capacity is not required to maintain the temperature at this time. In addition, excessive operation may also accelerate the wear of the equipment. (4) poor environmental adaptability: The traditional control method may not be able to well adapt to rapidly changing environmental conditions, such as sudden changes in the external air temperature or heat load changes caused by indoor personnel activities, which requires the air conditioner system to be able to respond quickly and accurately. Summary of the Invention

[0003] The present invention provides a control method, a control device, and an air conditioner for an air conditioner to solve the defects existing in the prior art and achieve the following technical effects: When approaching the set temperature, by restricting the operating speeds of the compressor and the fan, temperature fluctuations and energy waste can be effectively avoided while ensuring that the user comfort is not affected.

[0004] The control method for an air conditioner according to the first aspect embodiment of the present invention includes: Obtain the ambient temperature situation in the room where the air conditioner is located and the set target temperature for the room by the air conditioner; Control and adjust the operating parameters of the air conditioner according to the ambient temperature situation and the set target temperature.

[0005] According to an embodiment of the present invention, the step of obtaining the ambient temperature situation in the room where the air conditioner is located specifically includes: Every set time period, obtain the current ambient temperature in the room where the air conditioner is located and the previous ambient temperature before the set time period; Then the step of controlling and adjusting the operating parameters of the air conditioner according to the ambient temperature situation and the set target temperature specifically includes: Calculate the absolute value of the temperature difference between the current ambient temperature and the set target temperature, and use it as the first temperature difference; and calculate the second temperature difference between the current ambient temperature and the previous ambient temperature; Control and adjust the operating parameters of the air conditioner according to the first temperature difference and / or the second temperature difference.

[0006] In this way, the air conditioning system can monitor the minute changes in the indoor temperature in real time, and then make precise responses to ensure that the indoor temperature is stabilized near the target temperature set by the user. At the same time, the energy utilization efficiency is improved by intelligently regulating the compressor frequency and the fan speed.

[0007] According to an embodiment of the present invention, the step of controlling and adjusting the operating parameters of the air conditioner according to the first temperature difference and / or the second temperature difference specifically includes: Obtain the current operating mode of the air conditioner; Under the current operating mode, control and adjust the operating parameters of at least one of the compressor, the indoor fan, and the outdoor fan of the air conditioner according to the interval where the first temperature difference is located and / or the interval where the second temperature difference is located.

[0008] In this way, the above control strategy enables the air conditioning system to use more refined control means when approaching the target temperature, not only improving the accuracy of temperature adjustment, but also significantly enhancing the energy utilization efficiency.

[0009] According to an embodiment of the present invention, the step of controlling and adjusting the operating parameters of at least one of the compressor, the indoor fan, and the outdoor fan of the air conditioner according to the interval where the first temperature difference is located and / or the interval where the second temperature difference is located under the current operating mode specifically includes: In the cooling mode or the dehumidifying mode, if the first temperature difference is greater than or equal to the first set temperature difference and the second temperature difference is less than zero, then control the compressor, the indoor fan, and the outdoor fan to continue operating with their original parameters; Or, in the cooling mode or the dehumidifying mode, if the first temperature difference is less than the first set temperature difference and the second temperature difference is less than zero, then control the compressor to perform a frequency reduction operation, and control the indoor fan and the outdoor fan to perform a speed reduction operation.

[0010] This control strategy can effectively avoid overshoot of the temperature in the cooling mode or the dehumidifying mode of the air conditioner, ensure that the indoor temperature reaches the set value smoothly, and at the same time improve the energy efficiency and reduce unnecessary energy consumption.

[0011] According to an embodiment of the present invention, the step of, in the refrigeration mode or the dehumidification mode, controlling the compressor to perform a frequency reduction operation and controlling the indoor fan and the outdoor fan to perform a speed reduction operation according to that the first temperature difference is less than the first set temperature difference and the second temperature difference is less than zero specifically includes: In the refrigeration mode or the dehumidification mode, and the second temperature difference satisfies being less than zero; When the first temperature difference is less than the first set temperature and greater than or equal to the second set temperature difference, control the frequency of the compressor to continuously decrease at a first frequency reduction rate, control the rotational speed of the indoor fan to continuously decrease at a first indoor speed reduction rate, and control the rotational speed of the outdoor fan to continuously decrease at a first outdoor speed reduction rate; Or, when the first temperature difference is less than the second set temperature and greater than or equal to the third set temperature difference, control the frequency of the compressor to continuously decrease at a second frequency reduction rate, control the rotational speed of the indoor fan to continuously decrease at a second indoor speed reduction rate, and control the rotational speed of the outdoor fan to continuously decrease at a second outdoor speed reduction rate; Or, when the first temperature difference is less than the third set temperature, control the frequency of the compressor to continuously decrease at a third frequency reduction rate, control the rotational speed of the indoor fan to continuously decrease at a third indoor speed reduction rate, and control the rotational speed of the outdoor fan to continuously decrease at a third outdoor speed reduction rate; Wherein, the first frequency reduction rate is less than the second frequency reduction rate, the second frequency reduction rate is less than the third frequency reduction rate; and the first indoor speed reduction rate is less than the second indoor speed reduction rate, the second indoor speed reduction rate is less than the third indoor speed reduction rate; and, the first outdoor speed reduction rate is less than the second outdoor speed reduction rate, the second outdoor speed reduction rate is less than the third outdoor speed reduction rate.

[0012] In this way, the above steps can ensure that when the air conditioner is in the refrigeration or dehumidification mode and close to the set temperature, by gradually reducing the operating intensity of the compressor and the fan, the dual goals of both energy saving and maintaining temperature stability are achieved.

[0013] According to an embodiment of the present invention, the step of, in the current working mode, controlling and adjusting the operating parameters of at least one of the compressor, the indoor fan and the outdoor fan of the air conditioner according to the interval where the first temperature difference is located and / or the interval where the second temperature difference is located specifically includes: In the heating mode, when the first temperature difference is greater than or equal to the first set temperature difference and the second temperature difference is greater than zero, control the compressor, the indoor fan and the outdoor fan to all continue to operate with the original parameters; Alternatively, in the heating mode, if the first temperature difference is less than the first set temperature difference and the second temperature difference is greater than zero, control the compressor to perform a frequency reduction operation, and control the indoor fan and the outdoor fan to perform a speed reduction operation.

[0014] This control strategy can effectively avoid overshoot of the temperature of the air conditioner in the heating mode, ensure that the indoor temperature reaches the set value smoothly, improve the energy efficiency at the same time, and reduce unnecessary energy consumption.

[0015] According to an embodiment of the present invention, the step of, in the heating mode, if the first temperature difference is less than the first set temperature difference and the second temperature difference is greater than zero, controlling the compressor to perform a frequency reduction operation, and controlling the indoor fan and the outdoor fan to perform a speed reduction operation specifically includes: In the heating mode and when the second temperature difference is greater than zero; When the first temperature difference is less than the first set temperature and greater than or equal to the second set temperature difference, control the frequency of the compressor to continuously decrease at a first frequency reduction rate, control the speed of the indoor fan to continuously decrease at a first indoor speed reduction rate, and control the speed of the outdoor fan to continuously decrease at a first outdoor speed reduction rate; Alternatively, when the first temperature difference is less than the second set temperature and greater than or equal to the third set temperature difference, control the frequency of the compressor to continuously decrease at a second frequency reduction rate, control the speed of the indoor fan to continuously decrease at a second indoor speed reduction rate, and control the speed of the outdoor fan to continuously decrease at a second outdoor speed reduction rate; Alternatively, when the first temperature difference is less than the third set temperature, control the frequency of the compressor to continuously decrease at a third frequency reduction rate, control the speed of the indoor fan to continuously decrease at a third indoor speed reduction rate, and control the speed of the outdoor fan to continuously decrease at a third outdoor speed reduction rate; Wherein, the first frequency reduction rate is less than the second frequency reduction rate, the second frequency reduction rate is less than the third frequency reduction rate; and the first indoor speed reduction rate is less than the second indoor speed reduction rate, the second indoor speed reduction rate is less than the third indoor speed reduction rate; and the first outdoor speed reduction rate is less than the second outdoor speed reduction rate, the second outdoor speed reduction rate is less than the third outdoor speed reduction rate.

[0016] In this way, the above steps can ensure that when the air conditioner in the heating mode is close to the set temperature, by gradually reducing the operating intensity of the compressor and the fan, the dual goals of energy saving and temperature stability are achieved.

[0017] According to an embodiment of the present invention, in the current operating mode, the step of controlling and adjusting the operating parameters of at least one of the compressor, the indoor fan, and the outdoor fan of the air conditioner according to the interval where the first temperature difference is located and / or the interval where the second temperature difference is located specifically further includes: In the cooling mode or the dehumidifying mode, if the second temperature difference is greater than zero, then control the compressor, the indoor fan, and the outdoor fan to continue operating with the original parameters; Or, in the heating mode, if the second temperature difference is less than zero, then control the compressor, the indoor fan, and the outdoor fan to continue operating with the original parameters.

[0018] The control device of the air conditioner according to an embodiment of the second aspect of the present invention includes: An acquisition module, configured to acquire the indoor environmental temperature condition of the air conditioner and the set target temperature for the indoor of the air conditioner; A control module, configured to control and adjust the operating parameters of the air conditioner according to the environmental temperature condition and the set target temperature.

[0019] The air conditioner according to an embodiment of the third aspect of the present invention includes a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the program, it implements the control method of the air conditioner as described in the embodiment of the first aspect of the present invention.

[0020] The present invention proposes a new air conditioner control method. By real-time monitoring the indoor environmental temperature and comparing it with the set temperature, the compressor frequency and the fan speed are dynamically adjusted to achieve more precise temperature control and higher energy efficiency. When approaching the set temperature, this method can effectively avoid temperature fluctuations and energy waste by restricting the operating speeds of the compressor and the fan, while ensuring that the user comfort is not affected. Further, this method has at least the following advantages compared with the related technologies.

[0021] (1) Precise temperature control: By real-time comparing the set temperature with the environmental temperature, the present invention can accurately adjust the compressor frequency and the fan speed when approaching the set temperature, thereby more accurately controlling the indoor temperature, avoiding excessive temperature fluctuations, and improving user comfort.

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention with reference to the drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0033] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the embodiments of the present invention.

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0034] The control method, control device, and air conditioner of the present invention will be described below with reference to the accompanying drawings. Among them, before the detailed description of the embodiments of the present invention, the entire application scenario will be described first. The control method, control device, electronic device, and computer-readable storage medium of the air conditioner in the embodiments of the present invention can be applied not only to the local air conditioner but also to the cloud platform in the Internet field, or the cloud platform in other types of Internet fields, or can also be applied to third-party devices. Among them, the third-party devices may include various different types such as mobile phones, tablet computers, notebooks, in-vehicle computers, and other intelligent terminals.

[0035] Hereinafter, only the control method applicable to the air conditioner will be used as an example for illustration. It should be understood that the control method of the embodiments of the present invention can also be applicable to the cloud platform and third-party devices.

[0036] As Figure 1 shown, the control method of the air conditioner according to the first aspect embodiment of the present invention includes: Step S1, obtaining the environmental temperature situation in the room where the air conditioner is located and the set target temperature for the room by the air conditioner; Step S2, controlling and adjusting the operating parameters of the air conditioner according to the environmental temperature situation and the set target temperature.

[0037] According to the control method of the air conditioner in the embodiments of the present invention, its specific working process is as follows: First, in step S1, the air conditioner system needs to collect the environmental temperature situation and the set target temperature. Among them, the environmental temperature situation refers to the actual temperature of the room where the air conditioner is located, usually measured by an internal or external temperature sensor, and this data is used to reflect the current thermal condition of the room. The set target temperature is the ideal indoor temperature set by the user through the air conditioner controller. The user can adjust this value according to personal preferences or seasonal changes.

[0038] Next, in step S2, once the actual environmental temperature and the target temperature are collected, the air conditioning system enters the control logic phase. Specifically, the system compares the current environmental temperature with the target temperature set by the user to determine the difference between the two. Subsequently, based on the temperature difference, the air conditioning system automatically adjusts its operating parameters, including but not limited to the operating frequency of the compressor and the rotational speed of the fan. For example, if the environmental temperature is close to the target temperature, the system may reduce the frequency of the compressor and the rotational speed of the fan to avoid overcooling or overheating, thereby saving energy.

[0039] In addition, the system continuously monitors the environmental temperature and adjusts the operating parameters according to the real-time difference from the target temperature to ensure that the indoor temperature is stable within the target range while maximizing energy efficiency.

[0040] For example, in the cooling or dehumidifying mode, if the difference (△T) between the environmental temperature and the target temperature is less than a certain threshold and the temperature change rate (△T') is negative (i.e., the environmental temperature is decreasing), the system will start to limit the frequency of the compressor and the rotational speeds of the indoor and outdoor fans to avoid overcooling and save energy. Conversely, if the temperature change rate turns positive, the frequency limit is cancelled and the system returns to the normal operating state.

[0041] In the heating mode, the control logic is similar but in the opposite direction. That is, when the environmental temperature is lower than the target temperature and the temperature is rising, the system will limit the compressor frequency and the rotational speeds of the indoor and outdoor fans to avoid overheating.

[0042] In summary, the core of the control method of this air conditioner lies in real-time monitoring and dynamic adjustment to achieve precise temperature control and energy efficiency. By gradually reducing the activities of the compressor and the fan when approaching the target temperature, the system can maintain the stability of the indoor temperature while reducing unnecessary energy consumption, thereby achieving the effect of energy saving. This method not only improves the user experience but also reduces the operating cost, realizing the intelligentization of air conditioner control technology.

[0043] In the related art, in the process of the ambient temperature approaching the set temperature, the traditional air-conditioning control system often keeps the frequency of the compressor and the rotational speeds of the indoor and outdoor fans unchanged. This approach has the following disadvantages: (1) Imprecise temperature control: When the ambient temperature approaches the target temperature set by the user, due to the lack of corresponding adjustment of the compressor and fan speeds, the indoor temperature may fluctuate, and the ideal constant temperature effect cannot be achieved. For example, when approaching the set temperature, the air-conditioning system may still operate at full power, resulting in the temperature being too low or too high, affecting the user experience. (2) Energy waste: When the temperature approaches the set value, the full-power operation of the system not only causes energy waste but also may lead to an increase in electricity costs. Especially at night or during low-load periods, this excessive energy consumption is particularly obvious. (3) Low system efficiency: Since the compressor and fan do not slow down their operating speeds when approaching the target temperature, this leads to a reduction in system efficiency because such a high cooling or heating capacity is not required to maintain the temperature at this time. In addition, excessive operation may also accelerate the wear of the equipment. (4) Poor environmental adaptability: The traditional control method may not be able to well adapt to rapidly changing environmental conditions, such as sudden changes in the outside air temperature or heat load changes caused by indoor personnel activities, which requires the air-conditioning system to respond quickly and accurately.

[0044] Therefore, to solve the technical defects existing in the above-mentioned related art, the present invention proposes a new air-conditioning control method. By real-time monitoring the indoor environmental temperature and comparing it with the set temperature, the compressor frequency and fan speed are dynamically adjusted to achieve more precise temperature control and higher energy efficiency. When approaching the set temperature, this method can effectively avoid temperature fluctuations and energy waste by restricting the operating speeds of the compressor and fan, while ensuring that the user comfort is not affected.

[0045] Furthermore, this method has at least the following advantages compared with the related art.

[0046] (1) Precise temperature control: By real-time comparing the set temperature with the ambient temperature, the present invention can accurately adjust the compressor frequency and fan speed when approaching the set temperature, thereby more accurately controlling the indoor temperature, avoiding excessive temperature fluctuations, and improving user comfort.

[0047] (2) Improved energy efficiency: When the indoor temperature approaches the set temperature, the present invention reduces unnecessary energy consumption by restricting the compressor frequency and fan speed, improves energy utilization efficiency, and reduces operating costs.

[0048] (3) Low-cost implementation: Without changing the basic principle of the original air-conditioning system, the present invention optimizes temperature control and saves energy at the lowest cost by software controlling the compressor and fan.

[0049] (4) Intelligent adjustment: By using the strategy of temperature difference frequency limit, the present invention can dynamically adjust the operating parameters of the compressor and the blower according to the change of indoor temperature, making the air conditioning system more intelligent and adapting to different environmental requirements.

[0050] (5) Protection mechanism priority: The control strategy of the present invention is independent of other control mechanisms, but when an abnormality occurs or the system needs to be protected, the protection measures can be preferentially executed to ensure the safe and stable operation of the system.

[0051] (6) Strong adaptability: Whether in the cooling or heating mode, the present invention can adapt to different working conditions by adjusting the compressor frequency and the blower speed, ensuring efficient and energy-saving temperature control under various conditions.

[0052] In summary, by dynamically adjusting the operating parameters of components such as the compressor and the blower, the present invention not only improves the accuracy of temperature control, but also significantly enhances the energy utilization efficiency, providing users with a more comfortable, economical and environmentally friendly air conditioning use experience.

[0053] According to some embodiments of the present invention, the steps of obtaining the environmental temperature condition of the indoor where the air conditioner is located specifically include: Every set duration, obtain the current environmental temperature of the indoor where the air conditioner is located and the previous environmental temperature before the set duration.

[0054] In this embodiment, first, the system will preset a sampling period, that is, detect the environmental temperature once every fixed period of time (set duration). The selection of this period needs to consider the rate of temperature change and the timeliness of control response.

[0055] At the beginning of each sampling period, the temperature sensor built in or connected to the air conditioning system will measure and record the current indoor environmental temperature. This temperature value represents the real-time indoor thermal condition. At the same time, the system also needs to store the environmental temperature recorded in the previous sampling period. This means that before each new data is collected, the system will retain the environmental temperature value at the previous moment.

[0056] By comparing the current environmental temperature with the previously recorded environmental temperature, the system can calculate the temperature change rate (△T') during this period. This change rate is one of the key factors determining the adjustment of the air conditioner operating parameters.

[0057] This process is carried out cyclically, and the system will continuously obtain the latest environmental temperature and compare it with the historical data in order to dynamically adjust the operating parameters of the air conditioner according to the change of the environmental temperature.

[0058] In this way, the air conditioning system can monitor minute changes in the indoor temperature in real time, and then make precise responses to ensure that the indoor temperature is stabilized near the target temperature set by the user. At the same time, the energy utilization efficiency is improved by intelligently regulating the compressor frequency and the fan speed. This temperature monitoring mechanism based on timed sampling is an important part of implementing the control method of the present invention.

[0059] Further, the step of controlling and adjusting the operating parameters of the air conditioner according to the ambient temperature condition and the set target temperature specifically includes: Calculate the absolute value of the temperature difference between the current ambient temperature and the set target temperature, and use it as the first temperature difference; and calculate the second temperature difference between the current ambient temperature and the previous ambient temperature. Control and adjust the operating parameters of the air conditioner according to the first temperature difference and / or the second temperature difference.

[0060] In this embodiment, the principle of the above control method lies in monitoring the indoor temperature in real time, and intelligently adjusting the operating parameters of the air conditioning system according to the difference between the indoor temperature and the temperature set by the user, so as to achieve the effects of precise temperature control and energy saving.

[0061] Specifically, the system continuously monitors the indoor ambient temperature (ambient temperature Tai) and the target temperature set by the user (set temperature y), and calculates the difference (△T) between the two. When the ambient temperature approaches the set temperature (△T becomes smaller), the system adopts a differential temperature limit frequency strategy, that is, dynamically adjusts the compressor frequency (INV) and the speeds of the indoor and outdoor fans (Fan) according to △T and the rate of temperature change between two consecutive measurements (△T').

[0062] Among them, the control logic stipulates the adjustment methods of the compressor frequency and the fan speed under different combinations of △T and △T' to gradually reduce the output of the air conditioning system and avoid excessive cooling or heating.

[0063] According to some embodiments of the present invention, the step of controlling and adjusting the operating parameters of the air conditioner according to the first temperature difference and / or the second temperature difference specifically includes: Obtain the current working mode of the air conditioner; Under the current working mode, control and adjust the operating parameters of at least one of the compressor, the indoor fan, and the outdoor fan of the air conditioner according to the interval where the first temperature difference is located and / or the interval where the second temperature difference is located.

[0064] It can be understood that the first temperature difference (|△T|) reflects the difference between the current ambient temperature and the set target temperature. The second temperature difference (△T') measures the rate of change of the ambient temperature over time.

[0065] Specifically, the air conditioning system first determines the current operating mode, i.e., whether it is operating in the cooling / dehumidifying mode or the heating mode. According to the magnitudes of the first temperature difference and the second temperature difference, the system adjusts the operating parameters of the compressor, the indoor fan, and the outdoor fan to achieve more precise temperature control and higher energy efficiency.

[0066] For example, in the cooling / dehumidifying mode, when the ambient temperature is close to the set temperature (|△T| decreases), and the ambient temperature is still dropping (△T' < 0), the system will gradually reduce the compressor frequency and the fan speed to slow down the cooling process and avoid overcooling.

[0067] For another example, in the heating mode, when the ambient temperature is close to the set temperature (|△T| decreases), and the ambient temperature is still rising (△T' > 0), the system will similarly reduce the compressor frequency and the fan speed to slow down the heating process and avoid overheating.

[0068] In this way, the above control strategy enables the air conditioning system to, when approaching the target temperature, through more precise control means, not only improve the accuracy of temperature regulation but also significantly enhance the energy utilization efficiency.

[0069] In some specific embodiments of the present invention, in the current operating mode, the step of controlling and adjusting the operating parameters of at least one of the compressor, the indoor fan, and the outdoor fan of the air conditioner according to the interval where the first temperature difference is located and / or the interval where the second temperature difference is located specifically includes: In the cooling mode or the dehumidifying mode, if the first temperature difference is greater than or equal to the first set temperature difference and the second temperature difference is less than zero, then control the compressor, the indoor fan, and the outdoor fan to all continue to operate with the original parameters; Or, in the cooling mode or the dehumidifying mode, if the first temperature difference is less than the first set temperature difference and the second temperature difference is less than zero, then control the compressor to perform a frequency reduction operation, and control the indoor fan and the outdoor fan to perform a speed reduction operation.

[0070] In this embodiment, in the cooling mode or the dehumidifying mode, when the first temperature difference (△T) ≥ the first set temperature difference and the second temperature difference (△T') < 0, it means that the gap between the current ambient temperature and the set temperature is still large, and the ambient temperature is dropping towards the set temperature. In this case, the system determines that the current operating parameters of the air conditioner (compressor frequency, speeds of the indoor fan and the outdoor fan) are appropriate, so it will maintain these parameters unchanged and let the system continue to operate according to the current settings.

[0071] In the refrigeration mode or the dehumidification mode, when the first temperature difference (ΔT) < the first set temperature difference and the second temperature difference (ΔT') < 0, it indicates that the ambient temperature has approached the set temperature and the temperature is still decreasing. To avoid overcooling and wasting energy, the system will perform the following operations: (1) Compressor frequency reduction: Reduce the operating frequency of the compressor, decrease the refrigerant circulation speed, and thus reduce the refrigeration capacity. (2) Indoor fan and outdoor fan speed reduction: Reduce the rotational speed of the fans, decrease the air flow speed, and further slow down the refrigeration effect to make the indoor temperature more stably approach the set value.

[0072] In this way, by real-time monitoring of the first temperature difference (i.e., the difference between the current ambient temperature and the set temperature) and the second temperature difference (i.e., the difference between the ambient temperatures of two consecutive times), the system can judge the current temperature adjustment trend and the proximity to the target temperature, and thus intelligently adjust the operating parameters of the compressor, indoor fan, and outdoor fan. This control strategy can effectively avoid temperature overshoot, ensure that the indoor temperature smoothly reaches the set value, improve energy efficiency at the same time, and reduce unnecessary energy consumption.

[0073] Further, in the refrigeration mode or the dehumidification mode, according to the first temperature difference being less than the first set temperature difference and the second temperature difference being less than zero, the steps of controlling the compressor to perform frequency reduction operation and controlling the indoor fan and outdoor fan to perform speed reduction operation specifically include: In the refrigeration mode or the dehumidification mode, and satisfying that the second temperature difference is less than zero; When the first temperature difference is less than the first set temperature and greater than or equal to the second set temperature difference, control the frequency of the compressor to continuously decrease at the first frequency reduction rate, control the rotational speed of the indoor fan to continuously decrease at the first indoor speed reduction rate, and control the rotational speed of the outdoor fan to continuously decrease at the first outdoor speed reduction rate; Or, when the first temperature difference is less than the second set temperature and greater than or equal to the third set temperature difference, control the frequency of the compressor to continuously decrease at the second frequency reduction rate, control the rotational speed of the indoor fan to continuously decrease at the second indoor speed reduction rate, and control the rotational speed of the outdoor fan to continuously decrease at the second outdoor speed reduction rate; Or, when the first temperature difference is less than the third set temperature, control the frequency of the compressor to continuously decrease at the third frequency reduction rate, control the rotational speed of the indoor fan to continuously decrease at the third indoor speed reduction rate, and control the rotational speed of the outdoor fan to continuously decrease at the third outdoor speed reduction rate.

[0074] Among them, the first frequency reduction rate is less than the second frequency reduction rate, and the second frequency reduction rate is less than the third frequency reduction rate; and the first indoor speed reduction rate is less than the second indoor speed reduction rate, and the second indoor speed reduction rate is less than the third indoor speed reduction rate; and the first outdoor speed reduction rate is less than the second outdoor speed reduction rate, and the second outdoor speed reduction rate is less than the third outdoor speed reduction rate.

[0075] In this embodiment, in the refrigeration or dehumidification mode, when the air conditioning system detects that the first temperature difference (the difference between the current ambient temperature and the set temperature) is less than the first set temperature difference, and the second temperature difference (the difference between the current ambient temperature and the previously measured ambient temperature) is less than zero, this indicates that the ambient temperature is approaching the set temperature, and the temperature trend is decreasing towards the set temperature. To more precisely control the temperature and avoid overshooting and wasting energy, the system will adopt compressor frequency reduction and fan speed reduction strategies at different rates according to different first temperature difference intervals.

[0076] For example, assume that the first set temperature difference is 3°C, the second set temperature difference is 2°C, and the third set temperature difference is 1°C.

[0077] When the first temperature difference is between the first set temperature difference and the second set temperature difference (for example, 2°C ≤ first temperature difference < 3°C), the system will control the compressor frequency to continuously decrease at the first frequency reduction rate (for example, 1 Hz / 20 seconds), control the indoor fan speed to continuously decrease at the first indoor speed reduction rate (for example, 20 revolutions / 20 seconds), and control the outdoor fan speed to continuously decrease at the first outdoor speed reduction rate (for example, 50 revolutions / 20 seconds).

[0078] When the first temperature difference is between the second set temperature difference and the third set temperature difference (for example, 1°C ≤ first temperature difference < 2°C), the system will control the compressor frequency to continuously decrease at the second frequency reduction rate (for example, 1 Hz / 15 seconds), control the indoor fan speed to continuously decrease at the second indoor speed reduction rate (for example, 20 revolutions / 15 seconds), and control the outdoor fan speed to continuously decrease at the second outdoor speed reduction rate (for example, 50 revolutions / 15 seconds).

[0079] When the first temperature difference is less than the third set temperature difference (for example, first temperature difference < 1°C), the system will control the compressor frequency to continuously decrease at the third frequency reduction rate (for example, 1 Hz / 5 seconds), control the indoor fan speed to continuously decrease at the third indoor speed reduction rate (for example, 20 revolutions / 5 seconds), and control the outdoor fan speed to continuously decrease at the third outdoor speed reduction rate (for example, 50 revolutions / 5 seconds).

[0080] It should be noted that during the adjustment process, as the ambient temperature gets closer and closer to the set temperature, the rates of frequency reduction and speed reduction will gradually increase. This is because when approaching the set temperature, the precision requirement for temperature control is higher, to avoid excessive temperature fluctuations and at the same time save energy more effectively.

[0081] For example, if the current ambient temperature is 23°C, the set temperature is 22°C, and the previously measured temperature was 23.5°C, this means the first temperature difference is 1°C (less than the third set temperature difference), and the second temperature difference is -0.5°C (less than zero). In this case, the system will use the fastest rates of frequency reduction and speed reduction to fine-tune the temperature until the ambient temperature stabilizes near the set temperature.

[0082] In this way, the above steps can ensure that when the air conditioner is in the cooling or dehumidifying mode and approaching the set temperature, by gradually reducing the operating intensity of the compressor and the blower, the dual goals of energy conservation and temperature stability can be achieved.

[0083] In some other specific embodiments of the present invention, in the current working mode, the step of controlling and adjusting the operating parameters of at least one of the compressor, the indoor blower, and the outdoor blower of the air conditioner according to the interval where the first temperature difference is located and / or the interval where the second temperature difference is located specifically includes: In the heating mode, if the first temperature difference is greater than or equal to the first set temperature difference and the second temperature difference is greater than zero, then control the compressor, the indoor blower, and the outdoor blower to all continue to operate with the original parameters; Or, in the heating mode, if the first temperature difference is less than the first set temperature difference and the second temperature difference is greater than zero, then control the compressor to perform a frequency reduction operation, and control the indoor blower and the outdoor blower to perform a speed reduction operation.

[0084] For this embodiment, in the heating mode, the air conditioner control method of the present invention dynamically adjusts the operating parameters of the compressor, the indoor blower, and the outdoor blower by monitoring the difference between the indoor ambient temperature and the set target temperature, that is, the first temperature difference (|△T|), and the trend of temperature change, that is, the second temperature difference (△T').

[0085] Specifically, when the first temperature difference (|△T|) is greater than or equal to the first set temperature difference and the second temperature difference (△T') is a positive number, it indicates that the current ambient temperature has not yet approached the set temperature and the temperature is rising towards the set temperature. At this time, the system determines that the current operating parameters (compressor frequency, speeds of the indoor blower and the outdoor blower) are reasonable, so these parameters will be kept unchanged and the system will continue to operate in the existing state.

[0086] However, when the first temperature difference (|△T|) is less than the first set temperature difference and the second temperature difference (△T') is still positive, it means that the ambient temperature is already very close to the set temperature but is still rising. To avoid overheating and energy waste, the system will perform the following operations: (1) Compressor frequency reduction: Reduce the operating frequency of the compressor to decrease the heating capacity; (2) Fan speed reduction: Reduce the rotational speeds of the indoor fan and the outdoor fan to decrease the air circulation speed and further slow down the rising speed of the indoor temperature, making the indoor temperature approach the set value more stably.

[0087] In this way, through this dynamic control strategy, the air conditioning system can intelligently adjust the operating parameters of the compressor and the fan according to the real-time difference between the indoor temperature and the set temperature, as well as the trend of temperature change, so as to ensure that the indoor temperature can reach the set value smoothly and accurately, while improving the energy utilization efficiency and reducing unnecessary energy consumption.

[0088] Furthermore, in the heating mode, according to the step of controlling the compressor to perform frequency reduction operation and controlling the indoor fan and the outdoor fan to perform speed reduction operation when the first temperature difference is less than the first set temperature difference and the second temperature difference is greater than zero, specifically includes: In the heating mode and when the second temperature difference is greater than zero; When the first temperature difference is less than the first set temperature and greater than or equal to the second set temperature difference, control the frequency of the compressor to continuously decrease at the first frequency reduction rate, control the rotational speed of the indoor fan to continuously decrease at the first indoor speed reduction rate, and control the rotational speed of the outdoor fan to continuously decrease at the first outdoor speed reduction rate; Or, when the first temperature difference is less than the second set temperature and greater than or equal to the third set temperature difference, control the frequency of the compressor to continuously decrease at the second frequency reduction rate, control the rotational speed of the indoor fan to continuously decrease at the second indoor speed reduction rate, and control the rotational speed of the outdoor fan to continuously decrease at the second outdoor speed reduction rate; Or, when the first temperature difference is less than the third set temperature, control the frequency of the compressor to continuously decrease at the third frequency reduction rate, control the rotational speed of the indoor fan to continuously decrease at the third indoor speed reduction rate, and control the rotational speed of the outdoor fan to continuously decrease at the third outdoor speed reduction rate.

[0089] Among them, the first frequency reduction rate is less than the second frequency reduction rate, the second frequency reduction rate is less than the third frequency reduction rate; and the first indoor speed reduction rate is less than the second indoor speed reduction rate, the second indoor speed reduction rate is less than the third indoor speed reduction rate; and, the first outdoor speed reduction rate is less than the second outdoor speed reduction rate, the second outdoor speed reduction rate is less than the third outdoor speed reduction rate.

[0090] In this embodiment, in the heating mode, the air conditioning system intelligently adjusts the compressor frequency and the rotational speeds of the indoor and outdoor fans by monitoring the difference between the indoor environmental temperature and the set temperature (the first temperature difference △T) and the temperature change rate (the second temperature difference △T').

[0091] When the environmental temperature is close to the set temperature and the temperature change trend indicates that the temperature is moving towards the set temperature (i.e., △T'>0), the system takes different levels of frequency reduction and speed reduction measures according to the magnitude of △T.

[0092] The frequency reduction and speed reduction rates are classified into the first level, the second level, and the third level. Among them, for the first level: when △T is between the first set temperature and the second set temperature difference, the system adjusts at a lower frequency reduction rate and speed reduction rate; for the second level: when △T further decreases and is between the second set temperature and the third set temperature difference, the system adjusts at a higher frequency reduction rate and speed reduction rate; for the third level: when △T is less than the third set temperature, the system adjusts at the highest frequency reduction rate and speed reduction rate.

[0093] The relationship of the frequency reduction rates is as follows: the first frequency reduction rate < the second frequency reduction rate < the third frequency reduction rate. The relationship of the indoor fan speed reduction rates is as follows: the first indoor speed reduction rate < the second indoor speed reduction rate < the third indoor speed reduction rate. The relationship of the outdoor fan speed reduction rates is as follows: the first outdoor speed reduction rate < the second outdoor speed reduction rate < the third outdoor speed reduction rate.

[0094] For example, the first set temperature is 3℃, the second set temperature difference is 2℃, and the third set temperature is 1℃.

[0095] When the indoor temperature gradually rises from 18℃ to the set temperature of 21℃ and △T'>0, if 2℃≤△T<3℃, the system adjusts at the first frequency reduction rate and the first speed reduction rate (e.g., 1Hz / 20 seconds and 20 revolutions / 20 seconds); if 1℃≤△T<2℃, the system adjusts at a faster speed with the second frequency reduction rate and the second speed reduction rate (e.g., 1Hz / 15 seconds and 20 revolutions / 15 seconds); if △T further decreases to less than 1℃, the system adjusts at the fastest speed with the third frequency reduction rate and the third speed reduction rate (e.g., 1Hz / 5 seconds and 20 revolutions / 5 seconds) to ensure that the temperature is stable near the set value.

[0096] In this way, this hierarchical control strategy ensures that when approaching the set temperature, the system in the heating mode can adjust the operating parameters of the compressor and the fan in a more refined manner, thereby achieving precise temperature control and improving energy efficiency at the same time.

[0097] According to some embodiments of the present invention, in the current operating mode, the step of controlling and adjusting the operating parameters of at least one of the compressor, the indoor fan, and the outdoor fan of the air conditioner according to the range of the first temperature difference and / or the range of the second temperature difference specifically further includes: In the cooling mode or the dehumidifying mode, if the second temperature difference is greater than zero, control the compressor, the indoor fan, and the outdoor fan to continue operating with the original parameters; Alternatively, in the heating mode, if the second temperature difference is less than zero, control the compressor, the indoor fan, and the outdoor fan to continue operating with the original parameters.

[0098] It should be noted that in the cooling mode, if the second temperature difference (△T') is positive, this usually means that within the most recent measurement interval, the indoor temperature has not actually decreased as expected, or has even increased. This situation may be caused by reasons such as too short a detection time interval, external factor interference, air conditioner performance problems, or a small difference between the set temperature and the current temperature.

[0099] For example, if the detection time interval is set too short, due to natural fluctuations in the ambient temperature or measurement errors, it may seem that the temperature has not changed or has slightly increased, but in fact this change is not significant. Another example is that there are heat sources indoors (such as turned-on lights, operating electrical appliances, or human body heat dissipation), or external high temperatures penetrate through doors and windows, which may all make it difficult for the indoor temperature to drop rapidly. Another example is that the air conditioner system may have a decrease in cooling efficiency due to reasons such as a clogged filter, insufficient refrigerant, or system failure. Another example is that if the indoor temperature is already close to the set temperature, the air conditioner may be in an intermittent operating state, and it is normal for the temperature to change little in a short period of time.

[0100] In this case, the control strategy of the air conditioner should be to maintain the current operating parameters, rather than immediately adjusting the compressor frequency and the fan speed. This is because before there is a clear temperature decrease trend, any adjustment to the compressor and the fan may be unnecessary and may even lead to over-regulation of the temperature, affecting energy efficiency and user comfort.

[0101] If the second temperature difference (△T') is positive, the air conditioner control system should keep the current compressor frequency and fan speed unchanged and continue to observe the temperature change trend. Only when the temperature difference (△T) and the temperature change trend (△T') indicate that an adjustment is needed, then the corresponding frequency and speed adjustments are made.

[0102] This control logic ensures that in the cooling mode, even when encountering short-term temperature changes that are not obvious or abnormal, the air conditioning system can maintain a stable operating state, avoiding unnecessary energy waste and over-regulation. At the same time, it also allows the system to intelligently adjust the operating parameters according to the actual temperature change requirements to achieve the best temperature control and energy efficiency ratio.

[0103] The control logic and working principle in the heating mode are similar to those in the cooling mode, and will not be elaborated here.
