Description

Technical Field

[0001] The present invention belongs to the technical field related to fan air conditioners, and more specifically, particularly relates to a fresh air air conditioner dehumidification control system and method based on intelligent sensing prediction. Background Art

[0002] The existing air conditioner has basic functions such as dehumidification, refrigeration, and auxiliary heating. The principle of air conditioning dehumidification is that air containing water vapor contacts the condenser, and the moisture in the air condenses and liquefies to play a role in dehumidification. However, this dehumidification effect is limited. The prior art has proposed a device with better dehumidification effect. It uses the principle of material water absorption to make a rotatable moisture absorbing disk made of a material that can absorb water vapor. A partitioning device is provided at the air inlet of the moisture absorbing disk. For example, the circular air inlet is divided into two areas by a partition, namely the air inlet area and the drying area. Air enters from the air inlet to achieve the dehumidification effect, and the dry air is discharged from the drying area to the outside in reverse, and the rolling moisture absorbing disk itself is dehumidified, thereby achieving the effect of continuous dehumidification and avoiding the reduction of the dehumidification effect due to excessive moisture accumulation in the moisture absorbing disk itself.

[0003] For the existing dehumidification device, there are still the following technical problems:

[0004] First, in order to enable the desiccant disc to continuously dehumidify, how to keep the desiccant disc dry is an important issue. The existing technology uses a part of the air inlet area of ​​the desiccant disc to blow hot air in reverse to achieve a drying effect. This method occupies a part of the air inlet area of ​​the desiccant disc, reducing the effective utilization area of ​​the desiccant disc. In addition, friction will form between the partition and the air inlet end face of the desiccant disc, which will cause wear. There will be a gap between the partition and the air inlet end face of the desiccant disc, and the gas between the air inlet area and the drying area will flow cross-flow, and the two areas will affect each other.

[0005] Second, the existing dehumidification devices are not equipped with any intelligent control units. After adjusting the specified parameters, the existing devices cannot effectively predict the changes in indoor humidity, temperature and power consumption in the future. The existing devices cannot make balanced decisions on power consumption, humidity, temperature and response time. Therefore, how to provide a fresh air air conditioning dehumidification system and method that can intelligently predict the changing trends of humidity, temperature, etc. according to the user's parameter adjustment is the technical problem we need to solve.

[0006] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an intelligent sensing and predictive fresh air air conditioning dehumidification control system and method are provided, in order to achieve a more practical purpose.

[0051] A graded drying device is arranged in the cavity of the inner ring 46, and the graded drying device is connected to the drying frame 27 through a connecting frame 73. The graded drying device includes a heating cylinder 60 and a drying cylinder 47 arranged at both ends of the heating cylinder 60. A drying jet port 48 is provided on the side wall of the drying cylinder 47, and the drying jet port 48 is connected with the drying ventilation grooves on the inner ring 46 and the outer ring 42 in sequence. A windshield 75 is rotatably arranged in the drying cylinder 47, and a stepping motor 59 is arranged in the drying cylinder 47 for adjusting the ventilation area of ​​the drying jet port 48 blocked by the windshield 75. A connecting rod 50 is arranged at the shaft end of the stepping motor 59, and one end of the connecting rod 50 is connected to the windshield 75. The inner wall of the drying cylinder 47 is recessed to form an arc-shaped groove, and an elastic membrane 58 is covered at the opening of the arc-shaped groove. A vibration unit 57 is arranged on the surface of the arc-shaped groove, and the vibration axis of the vibration unit 57 is connected to the elastic membrane 58.

[0052] An intelligent control device 17 is also provided outside the housing 10, a first humidifier is provided at the air inlet of the induced draft fan 18, a second humidifier is provided at the air outlet of the dehumidification device 25, an input end of the intelligent control device 17 is electrically connected to the first humidifier and the second humidifier, respectively, and an output end of the intelligent control device 17 is electrically connected to the vibration unit 57 and the stepping motor 59, respectively.

[0053] In this embodiment, the intelligent control device 17 is used to control and detect corresponding data. During specific implementation, a deep learning computing unit is provided inside the intelligent control device 17, which is equipped with a neural network unit. The neural network unit is trained using the collected training samples, and the weights of the neural network unit are configured. After the parameters are determined, variables are input into the neural network unit, so that the neural network model can predict changes in environmental factors such as indoor temperature and humidity in the future, assist users in adjusting device parameters, and help users make better judgments.

[0054] After the parameters are set, the dehumidification process of the device is as follows: the annular dehumidification component rotates in the drying circular cavity 33, and the graded drying device sprays dry high-temperature gas outward through the drying jet port 48. The above-mentioned gas passes through the drying ventilation slot and passes through the isolation cavity from the inside to the outside. The dry gas takes away the moisture in the drying cotton 34 in the corresponding isolation cavity. As the annular dehumidification component continues to rotate, the graded drying device dehumidifies the drying cotton 34 in the isolation cavity at different angles in turn to achieve the effect of dynamic cycle dehumidification. Moreover, since the graded drying device is hidden in the inner ring 46 of the drying circular cavity 33, the graded drying device does not hinder the air inlet end of the drying circular cavity 33, and the graded drying device does not contact the air inlet end of the drying circular cavity 33. This design avoids the problem of cross-winding between the air inlet area and the drying area of ​​the traditional desiccant disc, and also avoids the friction loss problem of the air inlet port of the drying circular cavity 33, thereby reducing noise and increasing the service life of the product.

[0055] According to the user's parameter selection, the stepper motor 59 drives the wind shield 75 to rotate to a specified angle to adjust the ventilation area of ​​the drying jet port 48 blocked by the wind shield 75. When other parameters remain unchanged, the larger the ventilation area of ​​the drying jet port 48, the more conducive it is to drying the drying cotton 34.

[0056] According to the parameter selection, the vibration unit 57 is started at the set frequency and amplitude to drive the vibration unit 57 to vibrate. The vibration of the vibration unit 57 acts on the high-temperature dry gas in the drying cylinder 47 to make the gas tend to move back and forth in the drying cotton 34. The gas in the gap of the drying cotton 34 itself can be fully exchanged with the dry gas, and the drying effect is better.

The fixed frame 35 drives the elastic brush head to clean the air inlet end of the drying cotton 34.

[0060] During the dust cleaning process, the vibration device is started to drive the dust removal rod 39 to vibrate elastically. The dust removal rod 39 drives the elastic brush head to continuously move away from the air inlet end face of the drying cotton 34 to avoid the elastic brush head being stuck at the air inlet end of the drying cotton 34.

[0062] In this embodiment, as the drying cylinder 47 and the inner ring 46 rotate together, under the restriction of the slide rail, the ball drives the inner ring 46 and the external drying cotton 34 to move in a spiral trajectory. While the drying cotton 34 rotates, it moves along its own axis.

[0063] Preferably, the outer surface of the heating cylinder 60 is recessed to form a linear slide groove, the end of the drying cylinder 47 protrudes toward the linear slide groove to form a limit slider, and the limit slider slides in the linear slide groove.

The vibration is transmitted to the elastic membrane 58, and the elastic membrane 58 reciprocates to squeeze the gas in the drying cylinder 47.

[0065] Preferably, the inner wall of the drying circular cavity 33 is recessed in a direction away from the drying cotton 34 to form a transmission cavity 52, and a coaxially connected first transmission wheel 70 and a second transmission wheel 71 are rotatably arranged in the transmission cavity 52. ​​The transmission cavity 52 is also provided with a driving device for driving the first transmission wheel 70 and the second transmission wheel 71 to move synchronously, and the first transmission wheel 70 and the second transmission wheel 71 are respectively abutted against the outer rings 42 of the two annular dehumidification components.

[0068] Two independent motors drive the first transmission wheel 70 and the second transmission wheel 71 respectively, and a differential speed can be generated between the first transmission wheel 70 and the second transmission wheel 71. The advantage of this design is that when there is less moisture in the air, the dry cotton 34 near the air inlet has achieved the best dehumidification effect on the air, and even if the inner layer of dry cotton 34 is used, the moisture will not be further dehumidified. Therefore, the drive of the inner layer of dry cotton 34 can be reduced to reduce power consumption.

The end in contact with the air vibrates, and using the lever principle, the vibration is transmitted to the root of the elastic rod. At this time, the pressure of the root on the piezoelectric sensing layer increases, thereby increasing the sensitivity to the air flow rate.

[0073] The method of intelligent perception prediction of fresh air air conditioning dehumidification control system comprises the following steps:

[0074] S1: The air inlet 11 is provided with a deep learning processing unit, and a training sample is input into the deep learning processing unit. The training sample is:

[0075] Input vector: humidity value returned by the first humidifier, vibration amplitude of the vibration unit 57, vibration frequency of the vibration unit 57, angle signal of the stepper motor 59, temperature value of the heating resistor 62, air pressure value of the outside air, temperature value of the outside air, flow rate of the outside air, humidity value predicted by the local weather forecast, current time;

[0076] Target vector: predicted time length T1, humidity value sent back by the second humidifier, temperature value at the air outlet of the dehumidification device 25, and energy consumption of the device per unit time;

[0077] S2: The input vector can be further configured as: the rotation speeds N1 and N2 of the two groups of annular dehumidification components relative to the drying rack 27, and the rotation speed difference N0 between N1 and N2;

[0078] S3: The air inlet 11 is equipped with a safety control unit, which is equipped with a training mode. The training mode is to traverse all adjustable variables, including the vibration amplitude of the vibration unit 57, the vibration frequency of the vibration unit 57, the angle signal of the stepper motor 59, N1, N2 and N0, and record the time, the humidity value returned by the second humidifier, the temperature value at the air outlet of the dehumidification device 25, and the energy consumption of the device per unit time to form a training sample;

[0079] S4: The safety control unit is configured with a control mode. When the user adjusts the specified variables, the control mode uses the prediction capability of the deep learning processing unit to feed back the prediction results to the user. The prediction results include indoor humidity, temperature and equipment energy consumption at different time ends in the future.

[0080] Specific use of the present invention:

[0081] A deep learning computing unit is provided inside the intelligent control device 17, which is equipped with a neural network unit. The neural network unit is trained using the collected training samples, and the weights of the neural network unit are configured. After the parameters are determined, variables are input into the neural network unit. The neural network model can predict changes in environmental factors such as indoor temperature and humidity in the future. The safety control unit in the intelligent control device 17 assists the user in adjusting the device parameters. When the user adjusts a certain parameter, the system will display the changes in indoor temperature and humidity in the future, so that the user can make a reasonable choice.

[0082] According to the system prediction and recommendation, after the user sets the parameters, the dehumidification process of this device is:

[0083] The annular dehumidification component rotates in the drying circular cavity 33, and the graded drying device sprays dry high-temperature gas outward through the drying jet port 48. The above-mentioned gas passes through the drying ventilation slot and passes through the isolation cavity from the inside to the outside. The dry gas takes away the moisture in the drying cotton 34 in the corresponding isolation cavity. As the annular dehumidification component continues to rotate, the graded drying device dehumidifies the drying cotton 34 in the isolation cavity at different angles in turn to achieve the effect of dynamic cycle dehumidification. Moreover, since the graded drying device is hidden in the inner ring 46 of the drying circular cavity 33, the graded drying device does not hinder the air inlet end of the drying circular cavity 33, and the graded drying device does not contact the air inlet end of the drying circular cavity 33. This design avoids the problem of cross-winding between the air inlet area and the drying area of ​​the traditional desiccant disc, and also avoids the friction loss problem of the air inlet port of the drying circular cavity 33, thereby reducing noise and increasing the service life of the product.

[0084] According to the parameters, the stepper motor 59 drives the wind shield 75 to rotate to the set angle, and adjusts the ventilation area of ​​the drying jet port 48 blocked by the wind shield 75. When other parameters remain unchanged, the larger the ventilation area of ​​the drying jet port 48, the more conducive it is to drying the drying cotton 34.

[0085] According to the parameters, the vibration unit 57 is started according to the set frequency and amplitude to drive the vibration unit 57 to vibrate. The vibration of the vibration unit 57 acts on the high-temperature dry gas in the drying cylinder 47, so that the gas has a tendency to move back and forth in the drying cotton 34. The gas in the gap of the drying cotton 34 itself can be fully exchanged with the dry gas, and the drying effect is better.

[0086] Based on the user's selection, the system determines whether cleaning is required. If the cleaning command is activated, the dust removal motor 37 drives the rubber roller to drive the dust removal rod 39 to swing relative to the fixed frame 35. The fixed frame 35 drives the elastic brush head to clean the air inlet end of the dry cotton 34. The vibration device is started to drive the dust removal rod 39 to vibrate elastically. The dust removal rod 39 drives the elastic brush head to continuously move away from the air inlet end face of the dry cotton 34 to avoid the elastic brush head being stuck at the air inlet end of the dry cotton 34.

[0087] According to the user's settings, after N0 and N1 are determined, two independent motors drive the first transmission wheel 70 and the second transmission wheel 71 respectively, and a differential speed N0 is generated between the first transmission wheel 70 and the second transmission wheel 71. When there is less moisture in the air, the dehumidifying effect of the dry cotton 34 near the air inlet on the air is sufficient, and the system reduces the drive of the inner layer of dry cotton 34 to reduce power consumption.

[0088] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
