Description

Technical Field

[0001] The present application relates to the technical field of fan control, and in particular to a method for monitoring wind parameters of an intelligent combined air-conditioning unit. Background Art

[0002] A combined air conditioning unit is a device that integrates multiple air treatment functional sections. It is mainly used to achieve functions such as air mixing, filtering, cooling, heating, humidification, dehumidification, air supply and return air to meet the requirements of specific environments for air temperature, humidity, cleanliness and air flow velocity.

[0003] Combined air conditioning units are composed of multiple functional sections, such as fresh return air mixing section, filtration section, surface cooling section, heating section, humidification section, fan section, muffler section, medium efficiency filtration section, sterilization section and heat recovery section, etc. These functional sections can be combined according to specific application requirements to be suitable for air purification systems in various clean workshops, such as industrial electronics factories, precision machinery manufacturing factories, textile workshops, automobile spraying workshops, GMP pharmaceutical factories, cosmetics, food factories, pure water workshops, hospital operating departments, ICUs and other occasions.

[0004] In the standard dimension of energy-saving and environmental protection requirements, the energy consumption of combined air-conditioning units needs to be well controlled to meet the energy-saving requirements of the usage scenarios. Among them, wind resistance is an important factor that needs to be considered in the energy consumption of combined air-conditioning units. Increased wind resistance will lead to increased power consumption of the fan. If the fin spacing at the air inlet is reduced, the fan will increase the wind force, which will cause greater wind resistance, thereby increasing the power consumption of the fan. Therefore, the size of the wind resistance directly affects the energy consumption of the fan and the operating cost of the entire air-conditioning unit. However, most of the current combined air-conditioning units are still based on controlling wind speed and temperature, and the wind resistance is assumed to be constant. There is no algorithm specifically used in the control method of the combined air-conditioning unit to measure wind force parameters such as wind resistance in real time and then provide real-time reminders of the energy-saving effect of the combined air-conditioning unit. Therefore, an algorithm is needed for real-time measurement of wind force parameters such as wind resistance to provide real-time reminders of the energy-saving effect of the combined air-conditioning unit. Summary of the invention

[0005] In order to measure wind parameters such as wind resistance in real time so as to provide real-time reminders of the energy-saving effect of a combined air-conditioning unit, the present application provides a method for monitoring wind parameters of an intelligent combined air-conditioning unit.

[0006] The present application provides a method for monitoring wind parameters of an intelligent combined air conditioning unit, which adopts the following technical solution:

[0007] A method for monitoring wind parameters of an intelligent combined air conditioning unit comprises the following steps:

[0008] Control the fan of the unit to work at a set first working power; measure the wind speed of the incoming air to obtain first wind speed data; measure the humidity of the incoming air to obtain first humidity data; calculate the first air volume data according to the first wind speed data and the wind section data of the unit; measure the wind speed of the outgoing air to obtain first wind speed data; measure the humidity of the outgoing air to obtain first humidity data; calculate the first air volume data according to the first wind speed data and the wind section data of the unit; calculate the first efficiency parameter according to the first air volume data and the first air volume data;

[0009] Control the fan of the unit to work at a set second working power, wherein the value of the second working power is greater than the value of the first working power; measure the wind speed of the inlet air to obtain second inlet wind speed data; measure the humidity of the inlet air to obtain second inlet humidity data; calculate the second inlet air volume data according to the second inlet wind speed data and the inlet air section data of the unit; measure the wind speed of the outlet air to obtain second outlet wind speed data; measure the humidity of the outlet air to obtain second outlet humidity data; calculate the second outlet air volume data according to the second outlet wind speed data and the outlet air section data of the unit; calculate the second efficiency parameter according to the second inlet air volume data and the second inlet air volume data;

[0010] The difference between the first inlet humidity data and the first outlet humidity data is calculated as a first humidity difference, and the difference between the second inlet humidity data and the second outlet humidity data is calculated as a second humidity difference; the difference between the second humidity difference and the first humidity difference is calculated as a real-time humidity difference; if the real-time humidity difference is greater than a preset humidity reference difference, a humidity warning prompt is issued;

[0011] Calculating the difference between the second efficiency parameter and the first efficiency parameter as an efficiency difference, and issuing an energy consumption warning prompt if the efficiency difference is greater than a preset efficiency reference difference;

[0012] A weighted average of the real-time humidity difference and the efficiency difference is calculated as a real-time efficiency value. If the real-time efficiency value exceeds a preset efficiency range, an efficiency warning prompt is issued.

[0013] By adopting the above technical solution, by measuring the wind speed and humidity data of the inlet and outlet in real time and calculating the air volume and efficiency parameters, the method can provide instant feedback on the operating status of the air conditioning unit, which helps the operator to adjust the working status of the unit in time to optimize energy efficiency. By comparing the efficiency parameters under different working powers, the change of wind resistance can be indirectly identified, and then the energy consumption of the fan can be warned, which helps to reduce unnecessary energy consumption and reduce operating costs. By monitoring the humidity difference between the inlet and outlet air and comparing it with the preset humidity reference difference, the method can provide an early warning prompt for humidity control. By calculating the weighted average of the two-dimensional data of humidity and resistance, the efficiency value is obtained and compared with the preset efficiency threshold range to evaluate the overall efficiency of the air conditioning unit. Through automated monitoring and early warning, manual intervention can be reduced, the response speed and accuracy of the system can be improved, and intelligent management of the air conditioning unit can be realized. By optimizing the operation of the air conditioning unit and reducing energy consumption, the technical solution helps to reduce carbon emissions and meets the current global energy conservation, emission reduction and environmental protection requirements. In summary, the wind parameter monitoring method of the present application can not only improve the operating efficiency of the combined air-conditioning unit, but also reduce energy consumption and reduce environmental impact. It is an important technical means to realize an intelligent and green air-conditioning system.

[0014] Optionally, the method further comprises the following steps:

[0015] Controlling the fan of the unit to operate at a set third operating power; wherein the value of the third operating power is greater than the value of the second operating power;

[0016] Using the second inlet wind speed data to update the first inlet wind speed data;

[0017] Measure the incoming wind speed at the current third working power to obtain third inlet wind speed data and the opening ratio of the air valve at the air inlet; calculate the inlet wind coefficient according to the opening ratio of the air valve at the air inlet, and calculate new third inlet wind speed data according to the inlet wind coefficient and the third inlet wind speed data; use the new third inlet wind speed data to update the second inlet wind speed data; wherein, the new third inlet wind speed data = measured third inlet wind speed data × (1 + a1 × inlet wind coefficient).

[0018] By adopting the above technical solution, by controlling the fan of the unit to work at different working powers (first, second, and third working powers), the operating state of the fan can be adjusted more finely to adapt to different environments and needs, and more flexible energy efficiency management can be achieved. Using new air inlet speed data to update old data ensures that the monitoring system always calculates and makes decisions based on the latest data, improving the accuracy and real-time nature of monitoring. By calculating the air inlet coefficient in combination with the opening ratio of the air valve at the air inlet, the wind speed can be controlled and predicted more accurately. Dynamically adjusting the wind speed data according to the real-time air inlet coefficient enables the air conditioning unit to quickly respond to environmental changes, such as fluctuations in temperature and humidity, and changes in the opening of the air valve, improving the adaptability and stability of the system.

[0019] Optionally, the method further comprises the following steps:

[0020] Controlling the fan of the unit to operate at a set third operating power; wherein the value of the third operating power is greater than the value of the second operating power;

[0021] Using the second output wind speed data to update the first output wind speed data;

[0022] Measure the wind speed of the air outlet under the current third working power to obtain third outlet wind speed data; obtain the distance parameter between the flow equalizing plate at the air outlet and the air outlet; calculate the air outlet coefficient according to the distance parameter, calculate new third outlet wind speed data according to the third outlet wind speed data and the air outlet coefficient, and use the new third outlet wind speed data to update the second outlet wind speed data; wherein, the new third outlet wind speed data = measured third outlet wind speed data × (1 + a2 × air outlet coefficient).

[0023] By adopting the above technical solution, the method not only monitors and updates the inlet wind speed data, but also monitors and updates the outlet wind speed data, thus realizing comprehensive management of the wind speed of the entire air-conditioning unit. By calculating the outlet wind coefficient in combination with the distance data of the equalizing plate at the air outlet, and updating the outlet wind speed data accordingly, the outlet wind speed can be controlled more accurately and the airflow distribution of the air-conditioning unit can be optimized. Accurately controlling the outlet wind speed helps to reduce energy loss, improve the energy efficiency of the air-conditioning unit, and reduce energy consumption. By optimizing the outlet wind speed, the uniformity of air supply and the distribution of airflow can be better controlled, thereby improving indoor air quality.

[0024] Optionally, the method further comprises the following steps:

[0025] The opening ratio of the air valve at the air inlet is adjusted according to the positive correlation of the efficiency difference. The larger the efficiency difference, the larger the opening ratio; the smaller the efficiency difference, the smaller the opening ratio.

[0026] By adopting the above technical solution, the opening ratio of the air valve at the air inlet is dynamically adjusted according to the efficiency difference, which can respond to the change of wind resistance in real time and optimize the operating efficiency of the fan. By adjusting the opening ratio of the air valve in a positive correlation, the air volume can be increased when the wind resistance increases, reducing the energy consumption of the fan, and the air volume can be reduced when the wind resistance decreases, avoiding unnecessary energy waste.

[0027] Optionally, a multi-bag filter is provided in the unit, the multi-bag filter comprises a plurality of filter bags arranged in parallel, the opening of each filter bag is fixed on a sliding rod which can slide in a one-to-one correspondence, the position of the sliding rod in the multi-bag filter is different, and the opening degree of the corresponding filter bag is different; the sum of the opening areas of the filter bags in the multi-bag filter is fixed; wherein, the fewer the number of the opened filter bags, the larger the opening area of ​​the corresponding single filter bag;

[0028] The method further comprises the steps of:

[0029] The number of the filter bags opened in the multi-bag filter is adjusted in positive correlation with the efficiency difference. The larger the efficiency difference, the fewer the filter bags opened; the smaller the efficiency difference, the more the filter bags opened.

[0030] By adopting the above technical solution, the number of filter bags with openings can be dynamically adjusted according to the efficiency difference, so as to respond to the change of wind resistance in real time and optimize the airflow resistance and filtration efficiency of the filter. When the efficiency difference is large, it means that the resistance of air passing through the filter increases, which may be caused by filter blockage or insufficient fan power. At this time, the number of filter bags with openings should be reduced to increase the opening area of ​​the remaining filter bags, thereby reducing the resistance when air passes through. When the efficiency difference is small, it means that the air flow is smooth and the filter is in good working condition. At this time, the number of filter bags with openings can be increased to improve the overall filtration capacity of the filter while maintaining low resistance. By dynamically adjusting the number of openings of the filter bags, it is possible to avoid all filter bags from being subjected to high loads at the same time and extend the service life of the filter.

[0031] Optionally, a multi-bag filter is provided in the unit, the multi-bag filter comprises a plurality of filter bags arranged in parallel, the opening of each filter bag is fixed on a slidable push-pull rod in a one-to-one correspondence, the position of the push-pull rod in the multi-bag filter is different, and the opening and closing states of the corresponding filter bags are different; the sum of the opening areas of the filter bags in the multi-bag filter is fixed; when the push-pull rod is located at a first set position, the plurality of filter bags arranged in parallel are opened or closed in sequence at intervals; when the push-pull rod is located at a second set position, the opening and closing state of each filter bag is reversed;

[0032] The method further comprises the steps of:

[0033] When in the current set time period, the push-pull rod is located at the first set position;

[0034] When in the next set time period, the push-pull rod is located at the second set position.

[0035] By adopting the above technical solution, by periodically switching the opening and closing states of the filter bags, it is possible to ensure that the use time of each filter bag is relatively uniform, avoiding premature wear of some filter bags due to long-term use. This rotation method helps to balance the load of each filter bag, thereby extending the service life of the entire filter. Regularly switching the opening and closing states of the filter bags also helps prevent blockage and accumulation, because each filter bag has a chance to rest and clean for a period of time. This can improve the overall filtration efficiency of the filter and ensure the stable operation of the system. It reduces maintenance costs and workload and improves the reliability and availability of the equipment.

[0036] Optionally, the method further comprises the following steps:

[0037] The flow balancing distance from the flow balancing plate at the air outlet to the air outlet is adjusted according to the positive correlation of the efficiency difference. The larger the efficiency difference is, the larger the flow balancing distance is, the smaller the efficiency difference is, and the smaller the flow balancing distance is.

[0038] By adopting the above technical solution, the flow equalization distance from the flow equalizer plate at the air outlet to the air outlet is dynamically adjusted according to the efficiency difference, which can respond to the change of wind resistance in real time and optimize the air flow distribution and wind resistance of the air outlet. Increasing the flow equalization distance when the efficiency difference is large can reduce the wind resistance of the air outlet, reduce the energy consumption of the fan, and improve the energy efficiency of the air conditioning unit. Adjusting the flow equalization distance helps to improve the uniformity of the air outlet and ensure that the temperature and air flow distribution in the area covered by the air conditioner are more balanced. By optimizing the air flow distribution of the air outlet, the noise caused by air flow turbulence can be reduced and the comfort of the working environment can be improved. Reducing the excessive load on the fan and other components of the air conditioning unit can extend the service life of the equipment.

[0039] Optionally, a flow balancing module is provided at the air outlet, the flow balancing module includes at least two layers of stacked flow balancing plates, the size of the flow balancing aperture on the flow balancing module is positively correlated with the offset distance between the flow balancing plates, and the flow balancing plate method further includes the following steps:

[0040] The offset distance is adjusted according to the positive correlation of the efficiency difference value. The larger the efficiency difference value is, the smaller the offset distance is; and the smaller the efficiency difference value is, the larger the offset distance is.

[0041] By adopting the above technical solution, by setting at least two layers of stacked equalizer plates and adjusting the offset distance between the equalizer plates according to the efficiency difference, more precise airflow control can be achieved, and the uniformity and wind resistance of the air outlet can be optimized. Reducing the offset distance when the efficiency difference is large can reduce the wind resistance of the air outlet, reduce the energy consumption of the fan, and improve the energy efficiency of the air conditioning unit. Adjusting the offset distance between the equalizer plates helps to improve the uniformity of the air outlet and ensure that the temperature and airflow distribution in the air conditioning coverage area is more balanced. By optimizing the airflow distribution of the air outlet, the noise caused by airflow turbulence can be reduced and the comfort of the working environment can be improved.

[0042] In summary, the present application includes at least one of the following beneficial technical effects: it can provide a more efficient, energy-saving, and environmentally friendly operating mode for the combined air-conditioning unit, while also improving the stability and reliability of the system.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0050] The present application embodiment discloses a method for monitoring wind parameters of an intelligent combined air conditioning unit, referring to Figure 1 , including the following steps:

[0051] The fan of the control unit operates at the set first working power; the wind speed of the inlet air is measured to obtain the first inlet air speed data; the humidity of the inlet air is measured to obtain the first inlet humidity data; the first inlet air volume data is calculated according to the first inlet air speed data and the inlet air section data of the unit; the wind speed of the outlet air is measured to obtain the first outlet air speed data; the humidity of the outlet air is measured to obtain the first outlet humidity data; the first outlet air volume data is calculated according to the first outlet air speed data and the outlet air section data of the unit; the first efficiency parameter is calculated according to the first inlet air volume data and the first outlet air volume data. Among them, the first efficiency parameter = (first inlet air volume data - first outlet air volume data) / first inlet air volume data.

[0052] For example, the fan of the unit is set to a first operating power, such as 50% of the rated power.

[0053] The inlet wind speed is measured using an anemometer to obtain first inlet wind speed data, for example, 3 m / s.

[0054] Use a hygrometer to measure the inlet air humidity and obtain the first inlet humidity data, for example, 60% RH.

[0055] According to the inlet wind speed and the inlet cross-sectional data of the unit, for example, 0.5 square meters, the first inlet air volume data is calculated, that is, 3 meters / second×0.5 square meters=1.5 cubic meters / second.

[0056] Similarly, measure the wind speed and humidity of the outlet air and calculate the air volume, such as 1.4 cubic meters per second.

[0057] The first efficiency parameter = (1.5-1.4) / 1.5 = 6.66%.

[0058] The fan of the unit is controlled to work at the set second working power, wherein the value of the second working power is greater than the value of the first working power; the wind speed of the inlet air is measured to obtain the second inlet wind speed data; the humidity of the inlet air is measured to obtain the second inlet humidity data; the second inlet air volume data is calculated according to the second inlet wind speed data and the inlet air section data of the unit; the wind speed of the outlet air is measured to obtain the second outlet wind speed data; the humidity of the outlet air is measured to obtain the second outlet humidity data; the second outlet air volume data is calculated according to the second outlet wind speed data and the outlet air section data of the unit; the second efficiency parameter is calculated according to the second inlet air volume data and the second inlet air volume data. Wherein, the second efficiency parameter = (second inlet air volume data - second outlet air volume data) / second inlet air volume data.

[0059] For example, the operating power of the fan of the unit is adjusted to a second operating power, such as 75% of the rated power.

[0060] Repeat the above measurement steps to obtain the inlet wind speed (e.g., 3.5 m / s), inlet wind humidity (e.g., 58% RH), inlet air volume (e.g., 1.75 cubic meters / s), outlet wind speed, outlet wind humidity, and outlet air volume (e.g., 1.66 cubic meters / s) at the second working power.

[0061] The second efficiency parameter is calculated to be 5.14%.

[0062] The difference between the first inlet humidity data and the first outlet humidity data is calculated as the first humidity difference, and the difference between the second inlet humidity data and the second outlet humidity data is calculated as the second humidity difference; the difference between the second humidity difference and the first humidity difference is calculated as the real-time humidity difference; if the real-time humidity difference is greater than the preset humidity reference difference, a humidity warning prompt is issued. The preset humidity reference difference is obtained by looking up the table.

[0063] For example, assuming that at the first working power, the inlet humidity is 60% RH and the outlet humidity is 55% RH, then the first humidity difference is 5% RH.

[0064] At the second working power, the inlet humidity is 58%RH, the outlet humidity is 53%RH, and the second humidity difference is 5%RH.

[0065] The real-time humidity difference is the difference between the second humidity difference and the first humidity difference, that is, 0%RH.

[0066] Assume that the preset humidity reference difference is 2%RH. Since the real-time humidity difference does not exceed this value, no humidity warning prompt is issued.

[0067] The difference between the second efficiency parameter and the first efficiency parameter is calculated as the efficiency difference, and if the efficiency difference is greater than a preset efficiency reference difference, an energy consumption early warning prompt is issued. The preset efficiency reference difference is obtained by looking up a table.

[0068] For example, suppose the calculated efficiency difference is 0.05 (no unit, just an example), and the preset efficiency reference difference is 0.1.

[0069] Since the efficiency difference does not exceed the preset value, no energy consumption warning prompt is issued.

[0070] The weighted average of the real-time humidity difference and the efficiency difference is calculated as the real-time efficiency value. If the real-time efficiency value exceeds the preset efficiency range, an efficiency warning prompt is issued.

[0071] For example, assume that the weighted average of the real-time humidity difference and the efficiency difference is 0.025 (no unit, just an example), and the preset efficiency range is 0 to 0.05.

[0072] Since the real-time efficiency value does not exceed the preset range, no efficiency warning prompt is issued.

[0073] By measuring the wind speed and humidity data of the inlet and outlet in real time and calculating the air volume and efficiency parameters, the method can provide instant feedback on the operating status of the air conditioning unit, which helps the operator to adjust the working status of the unit in time to optimize energy efficiency. By comparing the efficiency parameters under different working powers, the change of wind resistance can be indirectly identified, and then the energy consumption of the fan can be warned, which helps to reduce unnecessary energy consumption and reduce operating costs. By monitoring the humidity difference between the inlet and outlet air and comparing it with the preset humidity reference difference, the method can provide early warning prompts for humidity control. By calculating the weighted average of the two-dimensional data of humidity and efficiency, the efficiency value is obtained and compared with the preset efficiency threshold range to evaluate the overall efficiency of the air conditioning unit. Through automated monitoring and early warning, manual intervention can be reduced, the response speed and accuracy of the system can be improved, and intelligent management of the air conditioning unit can be realized. By optimizing the operation of the air conditioning unit and reducing energy consumption, this technical solution helps to reduce carbon emissions and meets the current global energy conservation, emission reduction and environmental protection requirements. In summary, the wind parameter monitoring method of the present application can not only improve the operating efficiency of the combined air-conditioning unit, but also reduce energy consumption and reduce environmental impact. It is an important technical means to realize an intelligent and green air-conditioning system.

[0074] Reference Figure 2 , the method further comprises the following steps:

[0075] The fan of the control unit operates at a set third operating power; wherein the value of the third operating power is greater than the value of the second operating power.

[0076] The first inlet wind speed data is updated using the second inlet wind speed data. Assume that the measured third inlet wind speed data is 4 m / s.

[0077] The wind speed of the incoming air at the current third working power is measured to obtain the third incoming wind speed data and the opening ratio of the air valve at the air inlet; the air inlet coefficient is calculated according to the opening ratio of the air valve at the air inlet, and the new third inlet wind speed data is calculated according to the air inlet coefficient and the third inlet wind speed data.

[0078] The second inlet wind speed data is updated using the new third inlet wind speed data; wherein the new third inlet wind speed data=the measured third inlet wind speed data×(1+a1×inlet wind coefficient); wherein a1 is the first adjustment parameter.

[0079] The opening ratio of the air valve at the air inlet is 80% (i.e. 0.8). It is assumed that the air inlet coefficient is proportional to the opening ratio of the air valve, and the value of a1 is 0.1.

[0080] Then: air intake coefficient = 0.8 (because the air valve opening ratio is 80%). New third air intake speed data = 4 m / s × (1 + 0.1 × 0.8) = 4 m / s × 1.08 = 4.32 m / s. Wherein, a1 is a constant determined by experiment or experience, which is used to adjust the influence of the air intake coefficient on the wind speed. In other embodiments, a1 can be other values.

[0081] By controlling the fan of the unit to work at different working powers (first, second, and third working powers), the operating state of the fan can be adjusted more finely to adapt to different environments and needs, and more flexible energy efficiency management can be achieved. Using new inlet wind speed data to update old data ensures that the monitoring system always performs calculations and decisions based on the latest data, improving the accuracy and real-time nature of monitoring. By calculating the inlet wind coefficient in combination with the opening ratio of the air valve at the air inlet, the wind speed can be controlled and predicted more accurately. Dynamically adjusting the wind speed data according to the real-time inlet wind coefficient enables the air conditioning unit to quickly respond to environmental changes, such as fluctuations in temperature and humidity, and changes in the opening of the air valve, improving the adaptability and stability of the system. By continuously updating and calculating the wind speed data, the wind resistance and energy consumption can be more accurately measured, thereby achieving more refined energy consumption management, which helps to further reduce energy consumption and reduce operating costs. Real-time updating of wind speed data and inlet wind coefficient enables the system to quickly respond to changes in external conditions, improving the system's response speed and processing efficiency. The air conditioning unit has a stronger adaptive ability and can automatically adjust according to actual operating conditions to maintain the best operating state. By continuously monitoring and updating wind speed data, maintenance work can be better predicted and planned, unexpected downtime can be reduced, and system reliability and life can be improved. By optimizing the operation of wind turbines and reducing unnecessary energy consumption, it helps to reduce the impact on the environment and meet the requirements of sustainable development.

[0082] Reference Figure 3 In order to ensure timely update of data to facilitate more stable control of the system, in other implementations, the method further includes the following steps:

[0083] The fan of the control unit operates at a set third operating power; wherein the value of the third operating power is greater than the value of the second operating power.

[0084] The second wind speed data is used to update the first wind speed data; assuming that the measured third wind speed data is 3.5 m / s.

[0085] Measure the wind speed at the current third working power to obtain the third outlet wind speed data; obtain the distance parameter between the flow equalizer and the outlet; calculate the outlet wind coefficient according to the distance parameter, calculate the new third outlet wind speed data according to the third outlet wind speed data and the outlet wind coefficient, and use the new third outlet wind speed data to update the second outlet wind speed data. Among them, the new third outlet wind speed data = measured third outlet wind speed data × (1 + a2 × outlet wind coefficient); among them, a2 is the second adjustment parameter. The distance parameter between the flow equalizer and the outlet at the outlet is 20 cm; it is assumed that the outlet wind coefficient is inversely proportional to the distance parameter (that is, the closer the distance, the smaller the outlet wind coefficient), and the value of a2 is 0.05.

[0086] Then: Assume that the wind coefficient is directly proportional to the inverse of the distance. Therefore, for the assumed distance parameter of 20 cm, the corresponding wind coefficient value can be obtained by looking up the table. In this embodiment, the wind coefficient is 0.9. The new third wind speed data = 3.5 m / s × (1 + 0.05 × 0.9) = 3.5 m / s × 1.045 = 3.6575 m / s.

[0087] This method not only monitors and updates the inlet wind speed data, but also monitors and updates the outlet wind speed data, achieving comprehensive management of the wind speed of the entire air conditioning unit. By calculating the outlet wind coefficient in combination with the distance data of the equalizer at the air outlet, and updating the outlet wind speed data accordingly, the outlet wind speed can be controlled more accurately and the air flow distribution of the air conditioning unit can be optimized. Accurate control of the outlet wind speed helps to reduce energy loss, improve the energy efficiency of the air conditioning unit, and reduce energy consumption. By optimizing the outlet wind speed, the uniformity of the air supply and the distribution of the air flow can be better controlled, thereby improving the indoor air quality. This method allows the air conditioning unit to make adaptive adjustments based on the actual conditions of the air outlet (such as the distance of the equalizer), which improves the flexibility and adaptability of the system. Optimizing the outlet wind speed helps to reduce the noise generated by the fan and airflow, and improve the comfort of the working environment. By reducing the excessive load of the fan and unnecessary energy consumption, the service life of the air conditioning unit and its components can be extended. Continuously updated outlet wind speed data can help predict maintenance needs, achieve preventive maintenance, and reduce unexpected downtime and repair costs. This technical solution enables the air conditioning unit to automatically adjust the air speed according to environmental changes (such as temperature, humidity, and pressure changes) to maintain the best operating state. This technical solution enables the air conditioning unit to automatically adjust the air speed according to environmental changes (such as temperature, humidity, and pressure changes) to maintain the best operating state.

[0088] In order to respond to the change of wind resistance in real time and optimize the operating efficiency of the fan, the method also includes the following steps:

[0089] The opening ratio of the air valve at the air inlet is adjusted according to the positive correlation of the efficiency difference. The larger the efficiency difference, the larger the opening ratio; the smaller the efficiency difference, the smaller the opening ratio.

[0090] For example, if the efficiency difference is 1-3%, increase the opening ratio of the air valve from the original 50% to 60%. This increase is set based on system characteristics and experience and varies from system to system.

[0091] If the efficiency difference continues to increase to more than 3%, the opening ratio of the air valve will be increased, for example, to 70%.

[0092] On the contrary, if the efficiency difference is reduced to within 1%, the opening ratio of the air valve will be reduced from the original 50% to 40%.

[0093] By dynamically adjusting the opening ratio of the air valve at the air inlet according to the efficiency difference, the change of wind resistance can be responded to in real time and the operating efficiency of the fan can be optimized. By adjusting the opening ratio of the air valve in a positive correlation, the air volume can be increased when the wind resistance increases, the energy consumption of the fan can be reduced, and the air volume can be reduced when the wind resistance decreases to avoid unnecessary energy waste. This method enables the air conditioning unit to respond quickly to changes in wind resistance, improve the responsiveness and adaptability of the system, and ensure that the best performance can be maintained under different working conditions. By adjusting the opening ratio of the air valve, the load of the fan under high wind resistance conditions can be reduced and the service life of the fan can be extended. Optimizing the wind resistance and the opening ratio of the air valve helps to reduce the noise and vibration generated when the fan is running and improve the working environment. By adjusting the opening ratio of the air valve, the uniformity of air distribution can be improved and the air conditioning effect can be improved. By reducing the excessive load and unnecessary energy consumption of the fan, the maintenance cost and maintenance frequency can be reduced. This technical solution enables the air conditioning unit to automatically adjust according to environmental changes to maintain the best operating state and improve environmental adaptability. Through automated air valve adjustment, the possibility of human operation errors is reduced and the safety of operation is improved. Realize intelligent management of air-conditioning units and improve the automation level of the system.

[0094] In other embodiments, reference Figure 4 The unit is equipped with a multi-bag filter, which includes multiple filter bags arranged in parallel, and the opening of each filter bag is fixed on a sliding rod that can slide one by one. The position of the sliding rod in the multi-bag filter is different, and the corresponding filter bag opening degree is different; the total value of the opening area of ​​the filter bags in the multi-bag filter is fixed; among them, the fewer the number of open filter bags, the larger the opening area of ​​the corresponding single filter bag.

[0095] The method further comprises the steps of:

[0096] The number of open filter bags in the multi-bag filter is adjusted according to the positive correlation of the efficiency difference. The larger the efficiency difference, the fewer the number of open filter bags; the smaller the efficiency difference, the more the number of open filter bags.

[0097] For example, if the efficiency difference increases to 3%, the system will close some of the filter bags, such as reducing the number of open filter bags from 10 to 5. Since the total open area remains the same, the open area of ​​each filter bag that is still open will be increased to twice the original to maintain the same air flow.

[0098] If the efficiency difference is reduced to 1%, the system will increase the number of open filter bags, for example, from the original 10 to 15. In this way, the flow rate borne by each filter bag will be reduced, which will help reduce the load of a single filter bag and improve the filtration efficiency.

[0099] By dynamically adjusting the number of filter bags with openings according to the efficiency difference, the air flow resistance and filtration efficiency of the filter can be optimized in real time in response to changes in wind resistance. When the efficiency difference is large, it means that the resistance of air passing through the filter increases, which may be caused by filter blockage or insufficient fan power. At this time, the number of filter bags with openings should be reduced to increase the opening area of ​​the remaining filter bags, thereby reducing the resistance when air passes through. When the efficiency difference is small, it means that the air flow is smooth and the filter is in good working condition. At this time, the number of filter bags with openings can be increased to improve the overall filtration capacity of the filter while maintaining low resistance. By dynamically adjusting the number of openings of the filter bags, all filter bags can be prevented from being subjected to high loads at the same time, extending the service life of the filter. By reducing unnecessary energy consumption, this technical solution helps to reduce carbon emissions and meets the requirements of energy conservation, emission reduction and environmental protection. By reducing excessive load and unnecessary energy consumption of the filter, maintenance costs and repair frequency can be reduced. This technical solution enables the air conditioning unit to automatically adjust the number of openings of the filter bags according to environmental changes to maintain the best operating state.

[0100] In other embodiments, reference Figure 5 , a multi-bag filter is arranged in the unit, and the multi-bag filter includes a plurality of filter bags arranged in parallel, and the opening of each filter bag is fixed on a sliding push-pull rod one by one. The opening and closing states of the corresponding filter bags are different according to the different positions of the push-pull rod in the multi-bag filter. The sum of the opening areas of the filter bags in the multi-bag filter is fixed. When the push-pull rod is located at the first setting position, the plurality of filter bags arranged in parallel are opened or closed at intervals in sequence. When the push-pull rod is located at the second setting position, the opening and closing state of each filter bag is reversed.

[0101] The method further comprises the steps of:

[0102] When in the current set time period, the push-pull rod is located at the first set position;

[0103] When it is in the next set time period, the push-pull rod is located at the second set position.

[0104] For example, suppose the unit is set to have two time periods, each of which is 1 hour or 15 days. For example, taking the 1-hour period as an example:

[0105] In the first time period (0-1 hour), the push-pull rod is in the first setting position. At this time, the filter bags in the multi-bag filter will be opened or closed in sequence, such as the 1st, 3rd, 5th, 7th... filter bags are opened, and the 2nd, 4th, 6th, 8th... filter bags are closed. In this way, the air flow will be dispersed to the open filter bags, reducing the burden on a single filter bag.

[0106] In the second time period (1-2 hours), the push-pull rod moves to the second set position. At this time, the opening and closing state of each filter bag will be reversed, that is, the filter bags that were originally opened (1st, 3rd, 5th, 7th...) will be closed, and the filter bags that were originally closed (2nd, 4th, 6th, 8th...) will be opened. In this way, each filter bag has the opportunity to be used in different time periods.

[0107] By periodically switching the opening and closing states of the filter bags, it is possible to ensure that each filter bag is used relatively evenly, thus avoiding premature wear of some filter bags due to long-term use. This rotation method helps to balance the load of each filter bag, thereby extending the service life of the entire filter. Regularly switching the opening and closing states of the filter bags also helps prevent blockage and accumulation, because each filter bag has a chance to rest and clean for a period of time. This can improve the overall filtration efficiency of the filter and ensure the stable operation of the system. It reduces maintenance costs and workload, and improves the reliability and availability of the equipment.

[0108] The method further comprises the steps of:

[0109] The equalizing distance from the equalizing plate at the air outlet to the air outlet is adjusted according to the positive correlation of the efficiency difference. The larger the efficiency difference, the smaller the equalizing distance.

[0110] For example, if the efficiency difference increases to 3%, the system will use a mechanical device to move the flow plate outward to increase the flow distance. In this way, the air will have more space to diffuse and even out before flowing through the outlet, reducing the flow drop caused by the increase in efficiency.

[0111] If the efficiency difference is reduced to 1%, the system will move the flow equalizer inward to reduce the flow equalization distance. In this way, the air will flow through the air outlet more tightly, improving the outlet wind speed and the cooling or heating efficiency of the system.

[0112] Dynamically adjusting the flow-sharing distance from the flow-sharing plate at the air outlet to the air outlet according to the efficiency difference can respond to changes in wind resistance in real time and optimize the airflow distribution and wind resistance of the air outlet. Increasing the flow-sharing distance when the efficiency difference is large can reduce the wind resistance of the air outlet, reduce the energy consumption of the fan, and improve the energy efficiency of the air conditioning unit. Adjusting the flow-sharing distance helps improve the uniformity of the air outlet and ensure a more balanced temperature and airflow distribution in the area covered by the air conditioner. By optimizing the airflow distribution of the air outlet, the noise caused by airflow turbulence can be reduced and the comfort of the working environment can be improved. Reducing the excessive load on the fan and other components of the air conditioning unit can extend the service life of the equipment.

[0113] A flow balancing module is provided at the air outlet, and the flow balancing module includes at least two layers of stacked flow balancing plates, and the size of the flow balancing aperture on the flow balancing module is positively correlated with the offset distance between the flow balancing plates. The flow balancing plate method also includes the following steps:

[0114] The misalignment distance is adjusted according to the positive correlation of the efficiency difference. The larger the efficiency difference, the smaller the misalignment distance; the smaller the efficiency difference, the larger the misalignment distance.

[0115] For example, if the efficiency difference increases to 3%, the system will mechanically or electronically adjust the offset distance between the equalizer plates to reduce it. In this way, the equalizer aperture will also be reduced accordingly to reduce the air flow and improve the uniformity of the flow. This adjustment helps to reduce energy consumption and maintain stable operation of the system.

[0116] If the efficiency difference is reduced to 1%, the system will increase the offset distance. In this way, the flow-sharing aperture will be increased accordingly to accommodate more air flow and may improve the cooling or heating efficiency of the system.

[0117] By setting at least two layers of stacked equalizer plates and adjusting the offset distance between the equalizer plates according to the efficiency difference, more precise airflow control can be achieved, optimizing the uniformity and wind resistance of the air outlet. Reducing the offset distance when the efficiency difference is large can reduce the wind resistance of the air outlet, reduce the energy consumption of the fan, and improve the energy efficiency of the air conditioning unit. Adjusting the offset distance between the equalizer plates helps to improve the uniformity of the air outlet and ensure a more balanced temperature and airflow distribution in the area covered by the air conditioner. By optimizing the airflow distribution of the air outlet, the noise caused by airflow turbulence can be reduced and the comfort of the working environment can be improved.

Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
