[0002] With the continuous development of technology and the continuous improvement of people's awareness of energy conservation and environmental protection, air conditioner energy-saving control technology will also continue to develop and improve.

[0003] Currently, the energy-saving control method adopted by air conditioners mainly automatically adjusts the operating frequency of the compressor according to the indoor temperature and the set automatic adjustment operating parameters. However, this air conditioner energy-saving control method cannot be adjusted in real time according to different usage scenarios and time periods in combination with the user's usage requirements, reducing the convenience and comfort of use and the satisfaction with air conditioner products, restricting the user experience; in addition, since it is impossible to accurately judge the current environment and user needs, it is impossible to switch to the energy-saving mode in time, easily causing unnecessary energy waste. Summary of the Invention

[0005] The present invention provides an air conditioner system control method, including: obtaining the power supply monitoring voltage; comparing the magnitude of the power supply monitoring voltage with a preset voltage; based on the power supply monitoring voltage being less than or equal to the preset voltage, determining that the air conditioner system automatically selects a preset mode to operate; based on the power supply monitoring voltage being greater than the preset voltage, comparing the fluctuation range of the power supply monitoring voltage relative to the preset voltage; based on the fluctuation range, controlling the air conditioner to operate according to the automatically selected preset mode or according to the manually selected preset mode.

[0006] It should be noted that by determining whether the power supply monitoring voltage is greater than the preset voltage, in the case of power supply voltage fluctuations, it is timely determined whether it is necessary to adjust the air conditioner mode, so as to perform self-optimization and adjustment according to the real-time power supply situation, reduce unnecessary energy consumption losses, and when the power supply monitoring voltage is not greater than the preset voltage, the voltage may not be able to continue to maintain the operation of the first preset mode, determining that the air conditioner system automatically selects a preset mode to operate, realizing the automatic control of the air conditioner, and when the power supply monitoring voltage is greater than the preset voltage, further comparing the fluctuation range of the power supply monitoring voltage relative to the preset voltage, and thus, based on the fluctuation range, controlling the air conditioner to automatically adjust or manually adjust according to the user's usage requirements, avoiding excessive operation of the air conditioner and consuming too much electric energy, ensuring the reliability and consistency of the air conditioner operation, and enhancing the user's usage experience and usage comfort.

[0007] According to the present invention, a control method for an air conditioning system is provided. The preset modes include: a first preset mode, a second preset mode, and a third preset mode. The first preset mode is a rated power operation mode, and the rated powers of the second preset mode and the third preset mode decrease in sequence.

[0008] It should be noted that by setting different rated power configurations corresponding to the operation modes, it is convenient for the air conditioner to switch between the first operation mode, the second operation mode, and the third operation mode, ensuring the normal operation of the air conditioner. Without affecting the customer experience, the energy consumption is effectively reduced.

[0009] According to a control method for an air conditioning system provided by the present invention, based on the fluctuation range, controlling the air conditioner to operate according to a preset mode selected automatically or a preset mode selected manually includes: based on the fluctuation range being less than a first preset fluctuation range, controlling the air conditioning system to operate according to the first preset mode; based on the fluctuation range being greater than or equal to the first preset fluctuation range, controlling the air conditioning system to operate according to a preset mode selected automatically or a preset mode selected manually.

[0010] It should be noted that since the cooling / heating efficiency of the air conditioner varies under different preset modes, when the fluctuation range of the power supply monitored voltage relative to the preset voltage is less than the first preset fluctuation range, it is determined that the air conditioner can operate continuously and stably without adjusting the operation state due to slight voltage fluctuations. Therefore, the normal operation of the air conditioner can be maintained, frequent switching of the preset mode is avoided, the complexity of the system and the potential failure risk are reduced, and the user's satisfaction with the air conditioner performance is improved.

[0012] It should be noted that when the fluctuation range of the power supply monitored voltage relative to the preset voltage is greater than or equal to the first preset fluctuation range, a first alarm signal can be sent to the controller so that the user can timely ensure whether to manually select a preset mode according to the actual usage requirements of the user based on the alarm signal, thereby fully considering the user experience degree and enhancing the user's satisfaction with the air conditioner.

[0013] According to an air-conditioning system control method provided by the present invention, based on the fluctuation range being greater than or equal to a first preset fluctuation range, controlling the air-conditioning system to operate according to a preset mode selected automatically or according to a preset mode selected manually further includes: determining that no signal for manually selecting a preset mode sent by a controller is received within a first target time; based on the fluctuation range being less than a second preset fluctuation range, controlling the air-conditioning system to operate according to a second preset mode, where the second preset fluctuation range is greater than the first preset fluctuation range; based on the fluctuation range being greater than or equal to the second preset fluctuation range, controlling the air-conditioning system to operate according to a preset mode selected automatically or according to a preset mode selected manually.

[0014] It should be added that in the case where no signal for manually selecting a preset mode returned by the controller based on a first alarm signal is received within the first target time, it is further determined whether the fluctuation range of the power supply monitoring voltage relative to a preset voltage is less than the second preset fluctuation range, so that in the case where the fluctuation range of the power supply monitoring voltage relative to the preset voltage is less than the second preset fluctuation range, the air-conditioning is controlled to operate according to a second preset mode selected automatically, thereby ensuring the automatic control of the air-conditioning, and in the case where the fluctuation range is greater than or equal to the second preset fluctuation range, it is further confirmed whether to perform automatic control according to a preset mode selected automatically or to operate according to a preset mode selected manually, thereby fully considering the automatic control of the air-conditioning and the user's manual control, ensuring the reliability and consistency of the air-conditioning operation, and improving the user's use experience and comfort.

[0015] In addition, in the case where the fluctuation range of the power supply monitoring voltage relative to the preset voltage is less than the second preset fluctuation range, it is self-optimized and adjusted to the second preset mode to automatically control the air-conditioning according to the power grid power consumption situation, especially during the peak power consumption period, reduce the household power load, enhance the compatibility of the air-conditioning with a complex power grid environment, and expand the applicable range of the air-conditioning.

[0018] In addition, in the case where the signal of manually selecting a preset mode returned by the controller based on the second alarm signal is not received within the second target time, it is further automatically adjusted to a third preset mode through self-optimization to automatically control the air conditioner, reduce the household power load, further enhance the compatibility of the air conditioner with the complex power grid environment, and ensure the reliability and consistency of the air conditioner operation.

[0020] It should be noted that, according to the received signal of manually selecting a preset mode, the rated power of the corresponding preset mode is retrieved, so as to control the operation of the air conditioner according to the retrieved rated power, thereby facilitating flexible switching of the preset mode according to different user requirements, realizing precise distribution of energy, helping users better master the electricity cost, and contributing to balancing the working load of each component, prolonging the overall service life, and avoiding the situation of regional power outage rectification caused by excessive load burning of the transformer.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts belong to the scope of protection of the present invention.

[0029] Figure 1 A schematic flowchart of a method for controlling an air conditioning system according to the present invention is described. The method includes: S11, obtaining a power supply monitoring voltage; S12, comparing the magnitude of the power supply monitoring voltage with a preset voltage; S13, based on the power supply monitoring voltage being less than or equal to the preset voltage, determining that the air conditioning system automatically selects a preset mode to operate; S14, based on the power supply monitoring voltage being greater than the preset voltage, comparing the fluctuation range of the power supply monitoring voltage relative to the preset voltage; S15, based on the fluctuation range, controlling the air conditioner to operate in a preset mode selected automatically or in a preset mode selected manually.

[0030] It should be noted that the step numbers "S1N" in this specification do not represent the sequence of the air conditioning system control method. The following specifically combines Figures 2 - 3 Describe the air conditioning system control method of the present invention.

[0031] Step S11, obtaining a power supply monitoring voltage.

[0032] In this embodiment, obtaining the power supply monitoring voltage includes: monitoring the voltage at the power supply input in real time to obtain the power supply monitoring voltage. It should be noted that the power supply monitoring voltage is the voltage at the power supply input. By monitoring the voltage at the power supply input, it is convenient to subsequently determine whether to operate in a preset mode selected automatically or in a preset mode selected manually according to the real-time power supply fluctuation situation, so as to ensure that the air conditioner can achieve adaptive adjustment and can also adjust the operation of the air conditioner according to the user's usage requirements.

[0033] Step S12, comparing the magnitude of the power supply monitoring voltage with a preset voltage.

[0034] It should be noted that the preset voltage can be set according to the rated voltage of the internal components of the air conditioner and the power grid fluctuation range in the area where the air conditioner is located, and no further limitation is made here.

[0035] Step S13, based on the power supply monitoring voltage being less than or equal to the preset voltage, determining that the air conditioning system automatically selects a preset mode to operate.

[0036] In an alternative embodiment, the preset modes include: a first preset mode, a second preset mode, and a third preset mode. The first preset mode is the rated power operation mode, and the rated powers of the second preset mode and the third preset mode decrease in sequence.

[0037] It should be added that the rated power operation mode is 100% rated power. The second preset mode can be 75% rated power, and the third preset mode can be 50% rated power. The second preset mode and the third preset mode can be set according to actual design requirements and are not further limited herein. Additionally, when the air conditioner operates normally, it operates in the rated power operation mode.

[0038] Furthermore, by setting different rated power configurations corresponding to operation modes, it is convenient for the air conditioner to switch between the first operation mode, the second operation mode, and the third operation mode, ensuring the normal operation of the air conditioner. Without affecting the customer experience, the energy consumption is effectively reduced.

[0039] It should be noted that if the power supply monitored voltage is greater than the preset voltage, it is determined that the air conditioner can operate continuously and stably without adjusting the operation state due to slight voltage fluctuations. Therefore, the normal operation of the air conditioner can be maintained, avoiding the frequent switching of preset modes caused by voltage fluctuations within the normal range, reducing the complexity of the system and potential failure risks. Moreover, since no additional power adjustment is required within the normal voltage fluctuation range, the energy consumption and conversion losses are reduced, the energy utilization rate is improved, the air conditioner repair and maintenance costs are reduced, and users can enjoy a continuous, stable, and comfortable environment, improving user satisfaction with the air conditioner performance.

[0040] Step S14: Based on the power supply monitored voltage being greater than the preset voltage, compare the fluctuation range of the power supply monitored voltage relative to the preset voltage.

[0041] Step S15: Based on the fluctuation range, control the air conditioner to operate in the preset mode selected automatically or in the preset mode selected manually.

[0042] Specifically, referring to Figure 2 , controlling the air conditioner to operate in the preset mode selected automatically or in the preset mode selected manually based on the fluctuation range includes: based on the fluctuation range being less than the first preset fluctuation range, controlling the air conditioner system to operate in the first preset mode; based on the fluctuation range being greater than or equal to the first preset fluctuation range, controlling the air conditioner system to operate in the preset mode selected automatically or in the preset mode selected manually.

[0043] It should be added that, since the air-conditioning cooling / heating efficiency varies differently under different preset modes, the setting of the first preset fluctuation range needs to consider the lower limit of voltage tolerance of key components such as the compressor and motor under the first preset mode. In addition, since large fluctuations in the grid voltage in the area where the air conditioner is located will affect the voltage change, the setting of the first preset fluctuation range also needs to consider the local grid stability. Furthermore, since a voltage drop will reduce the performance of the air conditioner, thus affecting the user comfort, the first preset fluctuation range can also be set according to the voltage ratio corresponding to the performance degradation acceptable to the user. It should be noted that the setting of the first preset fluctuation range can be set according to the actual design requirements and will not be further limited here.

[0044] In addition, when the fluctuation range of the power supply monitoring voltage relative to the preset voltage is less than the first preset fluctuation range, it is determined that the air conditioner can operate continuously and stably without adjusting the operating state due to slight voltage fluctuations. Therefore, the normal operation of the air conditioner can be continued, avoiding frequent switching of preset modes, reducing the complexity of the system and potential failure risks, and improving the user's satisfaction with the air conditioner performance.

[0045] Furthermore, based on the fluctuation range being greater than or equal to the first preset fluctuation range, controlling the air-conditioning system to operate according to the automatically selected preset mode or the manually selected preset mode further includes: based on the fluctuation range being greater than or equal to the first preset fluctuation range, sending a first alarm signal to the controller; determining that a signal of the manually selected preset mode sent by the controller is received within the first target time, and the air-conditioning system operates according to the manually selected preset mode.

[0046] It should be noted that when the fluctuation range of the power supply monitoring voltage relative to the preset voltage is greater than or equal to the first preset fluctuation range, a first alarm signal can be sent to the controller so that the user can timely ensure whether to manually select the preset mode according to the actual usage requirements of the user, thus fully considering the user experience and enhancing the user's satisfaction with the air conditioner. In addition, the first alarm signal can be set according to the actual design requirements. For example, it can be a sound alarm and / or a color light flash. The sound alarm can be two beeps, etc., and will not be further limited here.

[0047] In addition, the first target time can be set according to the actual network delay and the user's response time. For example, when the network signal is good and the user confirms the control in a timely manner, the first target time can be set to one minute, and will not be further limited here.

[0048] In an alternative embodiment, controlling the air conditioning system to operate in a preset mode selected automatically or in a preset mode selected manually based on the fluctuation range being greater than or equal to a first preset fluctuation range further includes: determining that no signal for manually selecting a preset mode sent by the controller is received within a first target time; controlling the air conditioning system to operate in a second preset mode based on the fluctuation range being less than a second preset fluctuation range, where the second preset fluctuation range is greater than the first preset fluctuation range; and controlling the air conditioning system to operate in a preset mode selected automatically or in a preset mode selected manually based on the fluctuation range being greater than or equal to the second preset fluctuation range.

[0049] It should be noted that in the case where no signal for manually selecting a preset mode returned by the controller based on a first alarm signal is received within the first target time, it is further determined whether the fluctuation range of the power supply monitoring voltage relative to a preset voltage is less than a second preset fluctuation range, so that in the case where the fluctuation range of the power supply monitoring voltage relative to the preset voltage is less than the second preset fluctuation range, the air conditioner is controlled to operate in a second preset mode selected automatically, thereby ensuring the automatic control of the air conditioner, and in the case where the fluctuation range is greater than or equal to the second preset fluctuation range, it is further confirmed whether to perform automatic control in a preset mode selected automatically or to operate in a preset mode selected manually, thereby fully considering the automatic control of the air conditioner and the user's manual control, ensuring the reliability and consistency of the air conditioner operation, and enhancing the user's usage experience and comfort.

[0050] It is worth noting that in the case where the fluctuation range of the power supply monitoring voltage relative to the preset voltage is less than the second preset fluctuation range, it is self-optimized and adjusted to the second preset mode to automatically control the air conditioner according to the power grid power consumption situation, especially during peak power consumption periods, reduce the household power load, enhance the compatibility of the air conditioner with a complex power grid environment, and expand the applicable range of the air conditioner.

[0051] It should be added that since the air conditioner may malfunction or be damaged when the voltage drops to the critical value for safe operation, the second preset fluctuation range can be set according to the safe operation boundary of the device. Additionally, the second preset fluctuation range can also consider the upper and lower voltage limits of the second preset mode and the third preset mode, and the setting of the second preset fluctuation range can be made according to actual design requirements and will not be further limited here.

[0052] Specifically, based on the fluctuation range being greater than or equal to the second preset fluctuation range, controlling the air-conditioning system to operate according to the automatically selected preset mode or the manually selected preset mode further includes: based on the fluctuation range being greater than or equal to the second preset fluctuation range, sending a second alarm signal to the controller; determining that a signal of the manually selected preset mode sent by the controller is received within the second target time, and the air-conditioning system operates according to the manually selected preset mode; determining that a signal of the manually selected preset mode sent by the controller is not received within the second target time, and controlling the air-conditioning system to operate according to the third preset mode.

[0053] It should be noted that, based on the fluctuation range being greater than or equal to the second preset fluctuation range, a second alarm signal is sent to the controller, so as to further control the air conditioner to operate according to the manually selected preset mode based on the signal of the manually selected preset mode returned by the controller within the second target time, which is convenient for timely adjusting the power consumption of the air conditioner according to the user's usage requirements, avoiding excessive operation of the air conditioner and consuming too much electric energy, ensuring the reliability and consistency of the air conditioner operation, and improving the user's usage experience and comfort.

[0054] In addition, in the case that a signal of the manually selected preset mode returned by the controller based on the second alarm signal is not received within the second target time, it is further automatically adjusted to the third preset mode through self-optimization to automatically control the air conditioner, reduce the household power load, further enhance the compatibility of the air conditioner with the complex power grid environment, and ensure the reliability and consistency of the air conditioner operation. In addition, the second alarm signal can be set with reference to the above first alarm signal, and will not be repeated here.

[0055] In an alternative embodiment, the air-conditioning system operating according to the manually selected preset mode includes: determining the corresponding preset mode according to the signal of the manually selected preset mode sent by the received controller; determining the corresponding rated power according to the preset mode, and controlling the air-conditioning system to operate according to the determined rated power.

[0056] It should be noted that the execution subject of this step can be the microcontroller unit (MCU) of the air conditioner, that is, the MCU receives the signal of the manually selected preset mode, and according to the signal of the manually selected preset mode, retrieves the corresponding rated power, so as to control the operation of the air conditioner according to the retrieved rated power.

[0057] In an alternative embodiment, referring to Figure 3 , determining the corresponding rated power according to the preset mode includes: if the preset mode is the first preset mode, the rated power is 100%; if the preset mode is the second preset mode, the rated power is 75%; if the preset mode is the third preset mode, the rated power is 50%.

[0058] It should be added that according to the received signal of manually selecting a preset mode, the rated power corresponding to the preset mode is retrieved, so as to control the operation of the air conditioner according to the retrieved rated power, thereby facilitating flexible switching of the preset mode according to different user needs, achieving precise allocation of energy, helping users better master the electricity cost, and contributing to balancing the working loads of various components, extending the overall service life, and avoiding the situation of regional power outage rectification caused by excessive load on the transformer and burnout.

[0059] In summary, in the embodiment of the present invention, by determining whether the power supply monitoring voltage is greater than the preset voltage, in the case of power supply voltage fluctuations, it is timely determined whether it is necessary to adjust the preset mode of the air conditioner, so as to perform self-optimization and adjustment according to the real-time power supply situation, reduce unnecessary energy consumption losses, and in the case where the power supply monitoring voltage is not greater than the preset voltage, the voltage may not be able to continue to maintain the operation of the first preset mode, it is determined that the air conditioner system automatically selects a preset mode to operate, realizing the automatic control of the air conditioner, and in the case where the power supply monitoring voltage is greater than the preset voltage, further comparing the fluctuation range of the power supply monitoring voltage relative to the preset voltage, and thus the fluctuation range, controlling the air conditioner to automatically adjust or manually adjust according to the user's usage requirements, avoiding excessive operation of the air conditioner and consuming too much electric energy, ensuring the reliability and consistency of the air conditioner operation, and enhancing the user's usage experience and comfort.
