Description

Technical Field

[0001] This invention relates to the field of oxygen-generating air conditioning technology, and more specifically, to an air conditioner control method, an air conditioner, and a non-volatile storage medium. Background Technology

[0002] Currently, to ensure user comfort during air conditioning use, oxygen-generating modules are installed in air conditioners to supply oxygen to the indoor environment. Existing air conditioning control logic primarily relies on indoor oxygen sensors. When the detected indoor oxygen concentration is below a preset threshold, the oxygen-generating module is activated; conversely, when the concentration reaches or exceeds another threshold, the module is deactivated. Alternatively, the oxygen output of the air conditioner can be adjusted based on the number of people in the room, assuming that higher numbers of people result in higher oxygen consumption and thus higher oxygen flow rates, and vice versa.

[0003] However, due to the slow change in oxygen concentration, the existing control method based on oxygen sensors is difficult to adjust the output of the oxygen generation module in real time, resulting in a lag in the control of the oxygen generation module and an inability to respond quickly to changes in indoor oxygen concentration. In addition, the control strategy that relies solely on the number of people to adjust the oxygen output is too simplistic and does not fully consider the complexity of indoor oxygen consumption, making it impossible to achieve a precise match between oxygen output and consumption.

[0047] Specifically, this application confirms the oxygen flow compensation value L by monitoring the actual rate of change of indoor oxygen concentration and the actual difference ΔL between indoor oxygen concentration and target concentration threshold. 补偿 This allows for timely and proactive adjustment of oxygen output, significantly reducing control lag and ensuring that indoor oxygen concentration remains stable.

[0055] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0056] As mentioned in the background section, existing oxygen-generating air conditioners primarily rely on indoor oxygen sensors for control. When the indoor oxygen concentration is detected to be below a preset threshold, the oxygen-generating module is activated; conversely, when the concentration reaches or exceeds another threshold, the module is deactivated. Alternatively, the oxygen output of the air conditioner is adjusted by monitoring the number of people in the room, assuming that a larger number of people results in higher oxygen consumption and thus a higher oxygen flow rate, and vice versa. This control mechanism has significant limitations, considering only single variables such as the number of people or the oxygen concentration, neglecting other key factors affecting indoor oxygen concentration, such as the intensity of human activity, room ventilation, and oxygen consumption rate. The start-stop control of the oxygen-generating module exhibits significant lag, failing to accurately match indoor oxygen demand in practical applications, thus affecting the accuracy and timeliness of oxygen output. Therefore, to address the above technical problems, the air conditioner control method provided in this application, when the air conditioner is operating in oxygen-generating mode, includes: acquiring the actual rate of change of indoor oxygen concentration; acquiring the actual difference ΔL between the indoor oxygen concentration and the target concentration threshold; and determining the oxygen flow compensation value L based on the actual rate of change and the actual difference ΔL. 补偿 Wherein, the required indoor oxygen flow rate L = the current indoor oxygen flow rate L 当前 +Oxygen flow compensation value L 补偿 This method, by monitoring the actual rate of change of indoor oxygen concentration and the actual difference ΔL between the concentration and the target concentration threshold, can dynamically and in real time adjust the oxygen flow rate, rather than relying solely on a timer or a single oxygen concentration threshold. This approach more accurately reflects the immediate changes in indoor oxygen demand, ensuring a supply-demand balance between oxygen output and indoor consumption. Traditional control methods only activate the oxygen generation module after detecting an oxygen concentration below the threshold and immediately stop it once the concentration recovers, which easily leads to control lag and large fluctuations in indoor oxygen concentration. The method in this application, by continuously monitoring the rate of change, can predict concentration change trends in advance and adjust the oxygen flow rate ahead of time, avoiding large fluctuations in concentration and improving the stability of the indoor environment.

[0057] Please refer to Figure 1 This application provides an air conditioner control method. When the air conditioner is operating in oxygen production mode, the air conditioner control method includes:

[0058] Obtain the actual rate of change of indoor oxygen concentration;

[0059] Obtain the actual difference ΔL between the indoor oxygen concentration and the target concentration threshold;

[0060] Based on the actual rate of change and the actual difference ΔL, confirm the oxygen flow compensation value L. 补偿 ;

[0061] Wherein, the required oxygen flow rate L in the room = the current oxygen flow rate L in the room 当前 +Oxygen flow compensation value L 补偿 .

[0062] Compared to traditional control methods that start and stop based on fixed thresholds, the method of this application can adjust in real time according to the actual changes in indoor oxygen concentration, avoiding the over- or under-oxygenation that may occur in traditional control methods, ensuring that the indoor oxygen concentration is stable within an ideal range, and improving the accuracy of oxygen supply.

[0063] Specifically, this application confirms the oxygen flow compensation value L by monitoring the actual rate of change of indoor oxygen concentration and the actual difference ΔL between indoor oxygen concentration and target concentration threshold. 补偿 This allows for timely and proactive adjustment of oxygen output, significantly reducing control lag and ensuring that indoor oxygen concentration remains stable.

[0064] Indoor oxygen consumption varies depending on the time, location, and user. The method in this application, by considering the two key parameters of change rate and concentration difference, can better adapt to various usage scenarios and improve the versatility and practicality of the system.

[0065] Specifically, the air conditioner control method further includes: establishing an indoor oxygen concentration change rate setting; confirming the indoor oxygen concentration change rate setting to which the actual change rate belongs; establishing a difference threshold between the indoor oxygen concentration and the target concentration threshold; confirming the difference threshold to which the actual difference ΔL belongs; and confirming the oxygen flow compensation value L based on the indoor oxygen concentration change rate setting to which the actual change rate belongs and the difference threshold to which the actual difference ΔL belongs. 补偿 .

[0066] By confirming the actual rate of change and the corresponding setting and threshold value of the difference ΔL, the air conditioner can quickly identify the current indoor oxygen environment status, including the rate of increase or decrease in oxygen concentration and its deviation from the target value. This allows the system to respond rapidly and adjust the oxygen flow compensation value L. 补偿 It can promptly meet indoor oxygen demand, especially when there are changes in the intensity of human activity or changes in room ventilation, and can quickly adapt to environmental changes to maintain a stable indoor oxygen concentration.

[0067] This method continuously monitors changes in oxygen concentration and compensates for flow rate based on the rate of change and the difference from the target concentration. This maintains indoor oxygen concentration within a healthy range for humans while avoiding health problems such as oxygen intoxication that may be caused by excessively high concentrations, thus providing users with a healthier and more comfortable indoor environment.

[0068] By comparing the actual rate of change and the difference ΔL with preset levels and thresholds, the necessity and extent of oxygen flow compensation can be determined more accurately. This method not only improves control accuracy but also enhances system stability and reliability, reducing system failures or anomalies caused by inaccurate control.

[0069] This application's method avoids unnecessary energy waste by precisely controlling the working status of the oxygen generation module and the oxygen flow rate. Especially when the oxygen concentration is close to the target threshold, the flow rate compensation value L is finely adjusted. 补偿 This can reduce the frequent start-stop of the oxygen generation module, reduce energy consumption, improve energy utilization efficiency, and also reduce wear and tear on the oxygen generation module, extending the service life of the equipment.

[0070] In the specific implementation process, before obtaining the actual rate of change of indoor oxygen concentration, the air conditioner control method also includes: controlling the air conditioner to operate in oxygen production mode for a predetermined time.

[0071] During the process of the air conditioner switching to oxygen production mode and running for a predetermined time, the system first completes the initialization of the oxygen production module, including equipment preheating and system pressure balancing, to ensure that the oxygen production process starts from a stable state, thereby improving the accuracy and reliability of oxygen concentration monitoring and flow control.

[0072] During the initial operation phase, baseline oxygen concentration data of the indoor environment can be collected as a reference point for subsequent rate of change calculations. This helps the system establish an accurate baseline of the indoor oxygen environment, thereby more accurately determining the actual rate of change of oxygen concentration and avoiding misjudgments due to data fluctuations in the initial startup phase.

[0073] When switching between normal air conditioner operation and oxygen production mode, directly calculating the rate of change in oxygen concentration could negatively impact control performance due to environmental fluctuations at the moment of switching. By setting a predetermined operating period, the system can smoothly transition to rate-of-change-based control logic, avoiding the control discontinuity that might result from sudden switching.

[0074] In the embodiments provided in this application, the method for obtaining the rate of change of indoor oxygen concentration includes: obtaining the time required for a 0.1% change in indoor oxygen concentration.

[0075] Calculating the time required for a 0.1% change in indoor oxygen concentration provides a finer-grained monitoring indicator. This allows the system to detect minute changes in oxygen concentration more in real time, facilitating precise control of the oxygen generation module. Compared to monitoring larger concentration changes, this method of monitoring minute changes can detect fluctuations in oxygen concentration earlier, allowing for timely adjustments to oxygen output and maintaining stable indoor oxygen concentration.

[0076] The rate of change is calculated based on the time required for a 0.1% change in concentration, meaning the system can respond to changes in oxygen concentration more quickly. For example, when the number of people increases or the intensity of activity increases, oxygen consumption accelerates, and the system can quickly identify this trend of decreasing concentration and increase oxygen output in a timely manner to avoid insufficient oxygen supply.

[0077] Precise control of indoor oxygen concentration is crucial for user comfort and health. By calculating the time required for a 0.1% change, the system can manage the indoor oxygen environment more precisely, ensuring that the oxygen concentration is neither too high (avoiding health problems such as oxygen intoxication) nor too low (avoiding respiratory discomfort), providing users with a healthy and comfortable living or working environment.

[0078] Furthermore, methods for confirming the indoor oxygen concentration change rate level to which the actual rate of change belongs include:

[0079] The oxygen concentration change rate settings include a first rate setting and a second rate setting. The first rate setting is the oxygen concentration increase setting, and the second rate setting is the oxygen concentration decrease setting.

[0080] Confirm that the actual rate of change belongs to the first rate gear or the second rate gear;

[0081] The control method also includes: obtaining the oxygen flow compensation value L based on the confirmation results and the difference threshold to which the actual difference ΔL belongs. 补偿 .

[0082] By subdividing the rate of change into two levels, one for increasing and one for decreasing, the air conditioner can accurately identify the trend of changes in indoor oxygen concentration. Whether the concentration is increasing or decreasing, it can adjust the oxygen output of the oxygen generation module accordingly, achieving more comprehensive and bidirectional precise control of the indoor oxygen environment.

[0083] By differentiating between rising and falling oxygen concentration levels, the air conditioner control method can flexibly adjust the oxygen flow compensation value L according to different indoor environmental changes. 补偿 .

[0084] By distinguishing the direction of oxygen concentration changes, the system can more intelligently adjust the oxygen flow rate, avoiding unnecessary high load or low efficiency operation of the oxygen generation module.

[0085] By distinguishing between rising and falling speeds, the system can more accurately determine changes in oxygen concentration, avoiding misjudgments and instability that may result from single threshold control, thus enhancing the stability and reliability of the air conditioner control system.

[0086] Methods for constructing indoor oxygen concentration change rate settings include:

[0087] The time T1 required for the indoor oxygen concentration to increase by 0.1% is divided into multiple first time thresholds, and each of the multiple first time thresholds corresponds to a multiple first rate level.

[0088] By dividing time T1 into multiple thresholds to define different rate levels, the system can achieve precise control over changes in indoor oxygen concentration. This hierarchical control strategy allows the oxygen generation module to select the most appropriate output based on the actual rate of change in indoor oxygen concentration, avoiding the problems of excessive or insufficient oxygen that may result from overly coarse control.

[0089] When the rate of change in indoor oxygen concentration is clearly categorized into different levels, the air conditioner can quickly identify the current oxygen situation and immediately take corresponding control measures. This rapid response capability is crucial for maintaining a stable indoor oxygen concentration, especially when oxygen demand increases or decreases sharply, enabling timely adjustment of oxygen production flow to meet immediate needs.

[0090] Subdividing the rate of change into multiple levels helps the system operate more stably and reliably. By comparing the actual time required for the change with preset time thresholds, the system can accurately determine the trend of oxygen concentration change, avoiding misoperation caused by single threshold control and enhancing the robustness of the control logic.

[0091] Multiple first-speed gears include a first upshift gear, a second upshift gear, a third upshift gear, and a fourth upshift gear, ranging from fast to slow;

[0092] The multiple first-time thresholds, from shortest to longest, include: the first time period, the second time period, the third time period, and the fourth time period;

[0093] The first time period corresponds to the first upward gear; the second time period corresponds to the second upward gear; the third time period corresponds to the third upward gear; and the fourth time period corresponds to the fourth upward gear.

[0094] By dividing time T1 into different periods and corresponding to different acceleration levels, the system can dynamically adjust the working status of the oxygen generating module according to the real-time rate of change in indoor oxygen concentration. This dynamic adaptability ensures that no matter how the indoor environment changes, such as an increase or decrease in the intensity of human activity, the air conditioner can respond quickly and provide an immediate and appropriate oxygen replenishment.

[0095] Detailed setting of gears helps the system operate more stably and reliably. Under different environmental conditions, the system can quickly determine the current rate of change of oxygen concentration based on preset thresholds and take corresponding control measures, reducing the complexity of control logic and enhancing the robustness and reliability of the system.

[0096] Multiple first time thresholds include: 0 min < T1 ≤ 20 min; 20 min < T1 ≤ 40 min; 40 min < T1 ≤ 60 min; 60 min < T1;

[0097] Among them, 0min<T1≤20min is the first gear increase;

[0098] 20min < T1 ≤ 40min is the second gear increase;

[0099] 40min < T1 ≤ 60min is the third level of advancement;

[0100] 60min < T1 is the fourth gear shift.

[0101] The method for constructing indoor oxygen concentration change rate levels also includes: dividing the time T2 required for the indoor oxygen concentration to decrease by 0.1% into multiple second time thresholds, with each of the multiple second time thresholds corresponding to a multiple second rate level.

[0102] By dividing time T2 (the time required for oxygen concentration to decrease by 0.1%) into different levels, the system can comprehensively monitor the reduction in indoor oxygen concentration and make precise controls accordingly. This two-way monitoring (of both increases and decreases in oxygen concentration) ensures comprehensive management of the indoor oxygen environment, improving the integrity and effectiveness of control.

[0103] When indoor oxygen concentration begins to decline, the system can quickly identify and take measures based on the rate of decline (i.e., the rate of change). In scenarios with dense crowds or rapidly increasing oxygen consumption, this method can promptly activate or increase the output of the oxygen generation module to prevent the oxygen concentration from dropping to unsafe levels and protect user health.

[0104] The time required for oxygen concentration to decrease is divided into multiple thresholds, allowing the air conditioning system to intelligently adjust the oxygen flow compensation value L based on the current rate of decrease. 补偿 The system is able to take preventative measures based on the rate of decline before the oxygen concentration drops to a warning level.

[0105] Multiple second rate levels include a first decrease rate level, a second decrease rate level, a third decrease rate level, and a fourth decrease rate level, ranging from fast to slow; multiple second time thresholds, ranging from short to long, include a fifth time period, a sixth time period, a seventh time period, and an eighth time period;

[0106] The fifth time period corresponds to the first downward gear; the sixth time period corresponds to the second downward gear; the seventh time period corresponds to the third downward gear; and the eighth time period corresponds to the fourth downward gear.

[0107] By subdividing the time T2 required to reduce indoor oxygen concentration by 0.1% into multiple time periods, corresponding to different reduction levels, the system can accurately identify the rate of oxygen concentration decrease. This grading can more precisely reflect the dynamics of oxygen consumption, providing accurate data support for control strategies.

[0108] Based on the current rate of oxygen concentration decrease, the system intelligently selects the most appropriate oxygen output. In slower-decreasing gears (such as the fourth decreasing gear), the system can reduce the oxygen compensation to avoid excessive energy consumption; while in faster-decreasing gears, the system can increase the output to ensure that the oxygen supply meets the demand, thereby achieving efficient energy utilization.

[0109] By monitoring the rate of oxygen concentration decrease in real time and classifying levels according to preset time thresholds, the system can make more intelligent decisions based on data. With continuous optimization of the time thresholds, the system's control logic will become more refined, improving its overall performance.

[0110] Multiple second time thresholds include: 0 min < T2 ≤ 20 min; 20 min < T2 ≤ 40 min; 40 min < T2 ≤ 60 min; 60 min < T2;

[0111] Among them, 0min < T2 < 20min is the first downshift level;

[0112] 20min≤T2<40min is the second downshift level;

[0113] 40min≤T2<60min is the third downshift level;

[0114] 60min≤T2 is the fourth downshift.

[0115] Obtain oxygen flow compensation value L 补偿 The method includes: having multiple difference thresholds, each of which corresponds to a different oxygen flow compensation value L. 补偿 .

[0116] By dividing ΔL into multiple threshold segments, the system can adjust the oxygen flow rate using the most suitable compensation value based on different concentration deviations. This strategy allows the system to make the most appropriate flow rate adjustment based on the specific indoor oxygen concentration, achieving refined management of flow rate regulation.

[0117] When the indoor oxygen concentration deviates from the target value, the system can quickly identify the difference threshold range and immediately apply the corresponding L compensation value to adjust the flow rate. This rapid response mechanism is crucial for dealing with dynamic environmental factors such as changes in the intensity of indoor human activity and changes in ventilation conditions, ensuring the stability of indoor oxygen concentration and human comfort.

[0118] The air conditioner control method also includes: when the acquired real-time indoor oxygen concentration is at a preset concentration threshold, controlling the oxygen generation mode to stop operating; wherein, the preset concentration threshold is 19.5% to 23.5%.

[0119] The preset concentration threshold of 19.5% to 23.5% covers the normal atmospheric oxygen concentration range and the oxygen-rich environment suitable for the human body. When the system detects that the indoor oxygen concentration is stable within this healthy range, it stops operating the oxygen generation mode, which can avoid the risk of oxygen intoxication caused by excessively high oxygen concentration, and at the same time prevent the danger of hypoxia caused by excessively low oxygen concentration, thus ensuring the safety of the indoor environment for human health.

[0120] like Figure 2 and Figure 3 As shown, this application also provides an air conditioner, including a body and an oxygen generating module. The oxygen generating module is disposed on the body, and the body is also provided with a detection component for detecting the indoor oxygen concentration and oxygen flow rate. The air conditioner is applicable to the air conditioner control method of the above embodiments.

[0121] The oxygen-generating air conditioner includes an indoor unit 500 and an outdoor unit 400. An oxygen-generating module 700 is installed inside the outdoor unit 400. The oxygen-generating module 700 draws in the outdoor environment through its air inlet 720, and oxygen is separated by the oxygen-generating module 700 and delivered to the indoor unit 500 through the oxygen delivery port 710 and the oxygen delivery pipe 600.

[0122] like Figure 2 As shown, the control module for implementing this control method includes: an oxygen concentration sensor 100, an oxygen flow sensor 300, and a controller 200. The oxygen concentration sensor 100 can acquire the current indoor room oxygen concentration; the oxygen flow sensor 300 is used to acquire the oxygen output; the controller 200 receives the current indoor room oxygen concentration and feeds back the results of the oxygen flow monitoring and adjustment program to the controller to control the oxygen output of the current oxygen generation module.

[0123] Specific control logic:

[0124] Definition of indoor oxygen concentration: Normal oxygen concentration is generally 20.9% under normal atmospheric pressure. A concentration below 19.5% poses a risk of hypoxia. Maintaining an oxygen concentration between 21.5% and 23% is considered oxygen-rich and beneficial to human health. Concentrations above 23.5% fall within the medical oxygen concentration range and may cause oxygen narcosis in healthy individuals.

[0125] hypoxia Normal oxygen concentration Oxygen-rich Oxygen Intoxication

[0126] When the oxygen generating module is working, the oxygen flow controller outputs oxygen at a preset start-up flow rate L. The module starts its operation after a preset time, typically 30 minutes. Once the preset operating time is met, the oxygen flow monitoring and adjustment program begins, and the controller calculates the rate of change in indoor oxygen concentration. The rate of change is defined as the time required for a 0.1% change in indoor oxygen concentration. The calculation table is shown below, and the table content includes the following explanations:

[0127] The time unit is minutes (min).

[0128] For example: when the monitoring and adjustment program starts, if the oxygen concentration is 19.9% ​​and the timer starts, and it takes 30 minutes for the oxygen concentration to reach 20.0%, then the rate of change of concentration is determined to be "second escalation level".

[0129] First upshift 0＜T1≤20 Second upshift 20＜T1≤40 Third upshift 40＜T1≤60 Fourth upshift 60＜T1 Fourth downshift T1≤-60 Third downshift -60＜T1≤-40 Second downshift -40＜T1≤-20 First downshift -20＜T1＜0

[0130] After confirming the concentration change rate, and based on the difference between the current oxygen concentration and the preset oxygen target concentration ΔL, the preset oxygen target concentration is generally 21.5%. The controller then adds a corresponding flow control L to the monitoring and adjustment program based on the current oxygen production flow rate. 补偿 L 流量 =L 当前 +L 补偿 L 补偿 The preset control strategies are shown in the table below:

[0131]

[0132]

[0133] For example, an oxygen-generating air conditioner monitors the current indoor oxygen concentration at 20.1% and the current oxygen production flow rate at 3 L / min. After 30 minutes, the oxygen concentration rises to 20.2%. According to the adjustment program, the rate of change is confirmed to be in the "second escalation level" range, and the difference between the oxygen concentration and the preset target concentration ΔL is 21.5% - 20.2% = 1.3%. Therefore, the oxygen production flow rate will be adjusted to 3 - 0.4 = 2.6 L / min.

[0134] Special Note: The maximum oxygen flow rate is generally 5L / min. If the calculated flow rate exceeds 5L / min, the maximum range will apply. If the oxygen concentration in the monitored room is ≥23.5%, the oxygen generator will stop operating. The oxygen generator will start operating when the oxygen concentration is ≤19.5%.

[0135] This application proposes to monitor the deviation and rate of change between the indoor oxygen concentration and the preset concentration, and then control and adjust the oxygen output of the oxygen generating module to meet the indoor oxygen demand and improve comfort, while avoiding frequent start-stop or high-load work of the oxygen generating module and extending the module life.

[0136] This application also provides a non-volatile storage medium for storing the air conditioner control method of the above embodiments.

[0137] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0138] This application provides an air conditioner control method. When the air conditioner is operating in oxygen production mode, the air conditioner control method includes:

[0139] Obtain the actual rate of change of indoor oxygen concentration;

[0140] Obtain the actual difference ΔL between the indoor oxygen concentration and the target concentration threshold;

[0141] Based on the actual rate of change and the actual difference ΔL, confirm the oxygen flow compensation value L. 补偿 ;

[0142] Wherein, the required oxygen flow rate L in the room = the current oxygen flow rate L in the room 当前 +Oxygen flow compensation value L 补偿 .

[0143] Compared to traditional control methods that start and stop based on fixed thresholds, the method of this application can adjust in real time according to the actual changes in indoor oxygen concentration, avoiding the over- or under-oxygenation that may occur in traditional control methods, ensuring that the indoor oxygen concentration is stable within an ideal range, and improving the accuracy of oxygen supply.

[0144] Specifically, this application confirms the oxygen flow compensation value L by monitoring the actual rate of change of indoor oxygen concentration and the actual difference ΔL between indoor oxygen concentration and target concentration threshold. 补偿 This allows for timely and proactive adjustment of oxygen output, significantly reducing control lag and ensuring that indoor oxygen concentration remains stable.

[0145] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.
