Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0048] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.
[0049] The terms “comprising” and “including” indicate the presence of the described feature, whole, step, operation, element and / or component, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or collections thereof.
[0050] Figure 1 This is one of the flowcharts illustrating the air conditioning dehumidification control method provided by the present invention. For example... Figure 1 As shown, the air conditioning dehumidification control method provided in this embodiment of the invention includes: step 101, receiving the current humidity information in the room.
[0051] It should be noted that the execution subject of the air conditioning dehumidification control method provided in this embodiment of the invention is the air conditioning dehumidification control device.
[0052] The application scenario of the air conditioning dehumidification control method provided in this embodiment of the invention is that when the user activates the dehumidification mode of the air conditioning system, the dehumidification mode executed by the air conditioning system is adaptively adjusted by the humidity information of the space where the air conditioning system is located, which is fed back in real time by the sensing module.
[0053] The sensing module periodically collects humidity information within the space where the air conditioning system is located at specified time intervals and sends this humidity information to the air conditioning dehumidification control device. This embodiment of the invention does not specifically limit the working cycle of the sensing module.
[0054] Optionally, the sensor module can perform data acquisition operations at a default work cycle.
[0055] Optionally, the user can issue a cycle change command, causing the sensing module to accept and respond to the command, changing the working cycle to the cycle indicated by the command for data acquisition.
[0056] It should be noted that before step 101, the user needs to send an activation command through the transmission medium to activate the dehumidification mode of the air conditioning system, so that the indoor unit of the air conditioning system operates at the default fan speed of the mode, while the outdoor unit operates at the default frequency of the mode.
[0057] Optionally, the user can transmit activation commands through the control device and the air conditioning system via wireless communication to initialize the dehumidification mode of the air conditioning system.
[0058] Optionally, users can issue an activation command via voice interaction. The air conditioning system receives the activation command, performs voice recognition, and initializes the dehumidification mode.
[0059] Specifically, in step 101, after the air conditioner starts the dehumidification mode, the air conditioner dehumidification control device receives the current humidity information collected by the sensing module during the current working cycle.
[0060] The embodiments of the present invention do not impose a specific limit on the number of humidity sensors in the sensing module.
[0061] Optionally, the sensing module may include a humidity sensor, and the air conditioning dehumidification control device uses the humidity data collected by the humidity sensor as the current humidity information.
[0062] Optionally, the sensing module may include multiple humidity sensors, and the air conditioning dehumidification control device uses the humidity data collected by each humidity sensor to sum and average the data to obtain the current humidity information.
[0063] Step 102: Based on the current humidity information and historical humidity information, obtain the humidity decrease rate.
[0064] Among them, historical humidity information is determined based on humidity information collected in each historical period.
[0065] It should be noted that historical humidity information refers to the humidity information collected by the sensing module in one or more historical working cycles before the current working cycle, with the time period corresponding to the current working cycle as the base period.
[0066] Specifically, in step 102, the air conditioning dehumidification control device uses the current humidity information obtained in step 101 and the stored historical humidity information to calculate the humidity reduction.
[0067] The present invention does not specifically limit the calculation method for the humidity reduction in the embodiments.
[0068] Optionally, a humidity decrease P can be calculated using the current humidity information W1 of the current cycle and the historical humidity information W0 of the previous historical cycle, as follows:
[0069]
[0070] Alternatively, the current humidity information for this cycle can be used. n+1 Compared with the historical humidity information of the previous n historical periods [W1,…,W n ], calculate a set of humidity reduction rates [P1,…,P n The calculation method is as follows:
[0071]
[0072] Taking an example with n=3 and a sensor module operating cycle of 10 minutes, within the 30 minutes of operation, P1 represents the decrease in historical humidity information W1 within the first 10 minutes relative to historical humidity information W0 prior to this time period. P2 represents the decrease in historical humidity information W2 within the second 10 minutes relative to historical humidity information W1 within the first 10 minutes. P3 represents the decrease in historical humidity information W3 within the third 10 minutes relative to historical humidity information W2 within the second 10 minutes.
[0073] Step 103: If the humidity drop is less than the first threshold, send a first command to the outdoor unit to control the outdoor unit to increase its frequency.
[0074] It should be noted that the first threshold refers to the threshold set regarding the reduction rate.
[0075] Specifically, in step 103, the air conditioning dehumidification control device compares the humidity reduction obtained in step 102 with a pre-set first threshold, and the comparison results include: comparison success and comparison failure.
[0076] Successful comparison occurs when the humidity drop is less than the first threshold, indicating that the fresh air volume exceeds or approaches the air conditioning processing volume, meaning that the air conditioning system is in a poorly sealed space. In this case, the air conditioning dehumidification control device sends the first instruction to the outdoor unit.
[0077] The outdoor unit receives and responds to the first instruction, and starts to increase the frequency based on the default frequency of the dehumidification mode of the air conditioning system, increasing the cooling capacity so that the amount of cold air processed by the air conditioner exceeds the amount of fresh air, thereby achieving cooling and dehumidification.
[0078] If the comparison fails, it means that the humidity reduction is not less than the first threshold. This indicates that the fresh air volume has not exceeded the air handling capacity of the air conditioner, meaning that the air-conditioning system is in a well-sealed space. In this case, the air-conditioning dehumidification control device can control the air-conditioning system to maintain the current compressor frequency and fan speed, and perform cooling and dehumidification in the default dehumidification mode.
[0079] Preferably, the air conditioning dehumidification control device compares the set of humidity reduction values obtained in step 102 with a pre-set first threshold. If each humidity reduction value is less than the first threshold, the comparison is successful, and the indoor unit needs to be controlled to increase its frequency using the first command. Otherwise, the comparison fails, and the system can operate in the default dehumidification mode.
[0080] This invention calculates the humidity drop based on the current indoor humidity information and historical humidity information. Based on the humidity drop, it sends a first command to the outdoor unit to control the outdoor unit to increase its frequency. This enables the analysis of air leakage based on the ambient humidity and the adaptive adjustment of the cooling and dehumidification capacity. This ensures that the dehumidification function of the air conditioning system is not affected by the airtightness of the environment, improves the control accuracy of cooling and dehumidification, and enhances the dehumidification effect.
[0081] Based on any of the above embodiments, after sending a first instruction to the outdoor unit to control the outdoor unit to increase its frequency when the humidity drop is less than a first threshold, the method further includes sending a second instruction to the indoor unit to increase the indoor unit's fan speed.
[0082] Specifically, after step 103, as the cooling capacity increases due to the frequency increase of the outdoor unit, the air conditioning dehumidification control device sends a second command to the indoor unit to make adaptive adjustments to the operation mode of the indoor unit in order to shorten the residence time of humid air in the indoor unit.
[0083] The indoor unit receives and responds to the second command, controlling its fan speed to increase, so as to replace the air in the space with the outdoor air per unit time.
[0084] For example, the fan speed of the indoor unit can be increased to the highest setting.
[0085] In this embodiment of the invention, after the outdoor unit increases its frequency, a second command is sent to the indoor unit to control the indoor unit to adaptively adjust the fan speed as the cooling capacity increases. By increasing the fan speed, the residence time of humid air in the indoor unit can be shortened, thus avoiding the generation of excessive condensation.
[0086] Based on any of the above embodiments, the guide plate of the indoor unit includes a first guide plate and a second guide plate. The first guide plate is disposed in the upper half of the air outlet of the indoor unit, and the second guide plate is disposed in the lower half of the air outlet of the indoor unit.
[0087] After sending a second command to the indoor unit to increase its fan speed, the position of the indoor unit's guide plate is also adjusted, including:
[0088] In response to the second command, the first guide plate is moved to the first position, and the angle between the first position and the horizontal plane is greater than 0.
[0089] And / or,
[0090] In response to the second command, the second guide plate is moved to the second position, where the angle between the second position and the horizontal plane is less than 0.
[0091] Specifically, after step 103, as the cooling capacity increases due to the frequency increase of the outdoor unit, the air conditioning dehumidification control device sends a second command to the indoor unit to make adaptive adjustments to the operation mode of the indoor unit in order to shorten the residence time of humid air in the indoor unit.
[0092] The indoor unit receives and responds to the second command, and in addition to controlling the indoor unit to increase the fan speed, it also controls the guide plate at the air outlet of the indoor unit to change its position, so as to maximize the air outlet area and improve the air exchange efficiency.
[0093] For example, the air outlet of the indoor unit is designed with a double guide plate structure.
[0094] The first guide plate is located in the upper part of the air outlet. In response to the second command, the first guide plate is rotated to a position slightly above the middle.
[0095] The second guide plate is located in the lower half of the air outlet. In response to the second command, the second guide plate is rotated to a position slightly below the middle.
[0096] In this embodiment of the invention, after the outdoor unit increases its frequency, a second command is sent to the indoor unit to control the indoor unit to adaptively adjust the fan speed and guide plate position as the cooling capacity increases. By increasing the fan speed and the air outlet area, the residence time of humid air in the indoor unit can be shortened, thus avoiding the generation of large amounts of condensation.
[0097] Based on any of the above embodiments, before sending the first instruction to the outdoor unit, the method further includes: generating alarm information to control the indoor unit to broadcast the alarm information.
[0098] Specifically, in step 103, the air conditioning dehumidification control device compares the humidity reduction obtained in step 102 with a pre-set first threshold.
[0099] If the comparison result is successful, an alarm message is immediately generated. The air conditioning dehumidification control device encapsulates the alarm message and sends it to the voice broadcasting element in the air conditioning system via wireless communication technology (Wi-Fi), Bluetooth, or serial port for voice alarm.
[0100] The embodiments of the present invention do not specifically limit the electronic equipment on which the voice broadcasting element is based.
[0101] Optionally, the voice broadcasting element can operate based on the indoor unit, so that the indoor unit can issue a voice alarm with the content "The room is not sealed and there is a lot of air leakage. Please check and close the windows." It can also be combined with sound and light alarms for auxiliary prompts.
[0102] Optionally, the voice broadcasting element can operate on the user's control device (e.g., remote control, smart terminal, etc.) so that the control device can issue a voice alarm or text alarm with the content "The room is not sealed and there is a lot of air leakage. Please check and close the windows." It can also be combined with sound and light alarms for auxiliary prompts.
[0103] In this embodiment of the invention, when the humidity drop is less than a first threshold, an alarm message is generated, and the indoor unit is controlled to broadcast a voice announcement. It can analyze the current air leakage status of the space in real time and guide the user to ensure the space is airtight, thereby reducing the frequency increase operation of the outdoor unit, improving the control accuracy of cooling and dehumidification, and saving electricity.
[0104] Based on any of the above embodiments, after sending the first instruction to the outdoor unit, the method further includes: if the exhaust temperature of the outdoor unit does not meet the first preset condition, sending a second instruction to the outdoor unit to control the outdoor unit to reduce its frequency until the exhaust temperature meets the first preset condition.
[0105] The first preset condition is set based on the threshold of exhaust temperature.
[0106] It should be noted that the first preset condition refers to the limitation on exhaust temperature when the outdoor unit frequency changes. The first preset condition can be set according to the exhaust temperature threshold.
[0107] The embodiments of the present invention do not specifically limit the setting of the first preset condition.
[0108] Optionally, if the exhaust temperature threshold is a single value, then the first preset condition can be that the exhaust temperature is greater than or equal to the threshold, or the first preset condition can be that the exhaust temperature is less than or equal to the threshold.
[0109] Optionally, if the exhaust temperature threshold is a numerical range, then the first preset condition can be that the exhaust temperature is within a certain exhaust temperature threshold range.
[0110] Preferably, the first preset condition can be that the exhaust temperature is between 95°C and 98°C.
[0111] It should be noted that a temperature sensor is pre-installed at the exhaust port of the outdoor unit to collect the exhaust temperature in real time during the frequency increase process of the outdoor unit.
[0112] Specifically, after step 103, the air conditioning dehumidification control device compares the exhaust temperature of the outdoor unit at the current frequency with the first preset condition.
[0113] If the exhaust temperature at the current frequency meets the first preset condition, it means that the increased cooling capacity of the outdoor unit at the current frequency can make the air handling volume of the air conditioner exceed the fresh air volume. Therefore, the outdoor unit will maintain the current frequency of operation to maintain the current cooling and dehumidification effect.
[0114] If the exhaust temperature at the current frequency does not meet the first preset condition, it means that the increased cooling capacity of the outdoor unit at the current frequency makes the air handling volume much greater or much less than the fresh air volume.
[0115] If the exhaust temperature is lower than the lower limit of the first preset condition (i.e., 95℃), meaning the air conditioning processing volume is much smaller than the fresh air volume, then a third instruction is sent to the outdoor unit.
[0116] At this time, the third command has the same effect as the first command, causing the outdoor unit to receive and respond to the third command, continue to increase the frequency, and control the indoor unit to increase the fan speed in order to continue to increase the cooling capacity.
[0117] If the exhaust temperature is greater than or equal to the upper limit of the first preset condition (i.e., 98℃), meaning the air conditioning processing volume is much greater than the fresh air volume, then a third instruction is sent to the outdoor unit.
[0118] The outdoor unit receives and responds to the third instruction to reduce the frequency so that the exhaust temperature generated after frequency adjustment meets the first preset condition. Then, it maintains the reduced frequency to ensure sufficient cooling capacity and prevent the exhaust temperature from exceeding 98°C, which could damage the outdoor unit.
[0119] This invention adjusts the internal operating environment of the outdoor unit based on the exhaust temperature during the frequency increase process. If the exhaust temperature does not meet a first preset condition, a third command is generated to dynamically adjust the frequency of the outdoor unit until the corresponding exhaust temperature meets the first preset condition, at which point the outdoor unit maintains the adjusted frequency. This allows for real-time monitoring of the outdoor unit's operating environment and dynamic adjustment of its frequency, improving the control accuracy of cooling and dehumidification while preventing damage to electronic components and saving power.
[0120] Based on any of the above embodiments, after obtaining the humidity reduction, the method further includes: if the humidity reduction is not less than a first threshold and the current humidity information does not meet the second preset condition, sending a fourth instruction to the outdoor unit to control the outdoor unit to reduce its frequency until the current humidity information meets the second preset condition.
[0121] The second preset condition is set based on a humidity threshold.
[0122] It should be noted that the second preset condition refers to the humidity limit in the space when the air conditioning system is cooling and dehumidifying. The first preset condition can be set according to the humidity threshold.
[0123] The embodiments of the present invention do not specifically limit the setting of the second preset condition.
[0124] Optionally, if the humidity threshold is a single numerical value, the second preset condition can be that the humidity is greater than or equal to the threshold, or the second preset condition can be that the humidity is less than or equal to the threshold.
[0125] Optionally, if the humidity threshold is a numerical range, then the second preset condition can be that the humidity is within a certain humidity threshold range.
[0126] Preferably, the second preset condition can be a humidity greater than 60%, that is, a more suitable humidity obtained from empirical data.
[0127] Specifically, after step 102, if the comparison result between the humidity reduction obtained in step 102 and the first threshold is a failure, the frequency of the outdoor unit and the wind speed of the indoor unit remain unchanged, and the air conditioning dehumidification control device compares the current humidity information received in step 101 with the pre-set second preset condition.
[0128] If the current humidity meets the second preset condition, it means that the air conditioning system has reduced the current humidity under the current dehumidification mode, but has not reduced it to the humidity threshold (i.e., 60%) indicated by the second preset condition. In this case, the frequency of the outdoor unit and the fan speed of the indoor unit can remain unchanged, and the dehumidification operation can continue in the current dehumidification mode.
[0129] If the current humidity does not meet the second preset condition, it means that the air conditioning system has reduced the current humidity under the current dehumidification mode and it has reduced it to below the humidity threshold (i.e., 60%) indicated by the second preset condition. Then, a fourth instruction is sent to the outdoor unit.
[0130] The outdoor unit receives and responds to the fourth command, reduces the frequency and cooling capacity, so that after the humidity generated by the frequency adjustment meets the second preset condition, it maintains the reduced frequency operation, so that the humidity after dehumidification is maintained at about 60%.
[0131] Figure 2 This is the second flowchart illustrating the air conditioning dehumidification control method provided by this invention. For example... Figure 2 As shown, a specific implementation method for controlling air conditioning dehumidification is given:
[0132] The humidity sensor provides feedback every ten minutes. If, with the dehumidification function activated, the indoor humidity does not decrease or decreases by less than 5% after three consecutive checks, there is reason to suspect excessive air leakage in the room. The fresh air volume may exceed or approach the air conditioning's processing capacity. At this point, the indoor unit will issue a voice alarm, reminding the room owner that there is a significant air leak and requesting them to check and close the windows. Simultaneously, the outdoor unit compressor will increase its frequency, increasing cooling capacity. When the compressor exhaust temperature reaches its maximum value of 95℃, the frequency increase will stop, and the unit will operate smoothly at the current frequency. To prevent the exhaust temperature from exceeding 98℃ and damaging the compressor, the exhaust temperature will be fed back every three minutes. When the exhaust temperature shows an upward trend, the compressor will begin to reduce its frequency until the exhaust temperature drops below 95℃, at which point it will stop reducing the frequency and maintain stable operation. To prevent condensation inside the air conditioner, the indoor unit's fan speed will be increased to the highest setting to shorten the residence time of humid air inside the unit and prevent excessive condensation. The indoor unit's air outlet is equipped with dual guide plates; the upper guide plate is rotated to a position slightly above the middle, and the lower guide plate is rotated to a position slightly below the middle.
[0133] When the average indoor humidity is detected to decrease by more than 5% three times in a row, the compressor frequency and indoor unit fan speed remain unchanged until the indoor humidity reaches 60%-65%. Then the compressor starts to slowly reduce its frequency until the humidity stops changing. Finally, the humidity is maintained between 55%-60%, and the compressor frequency and indoor unit fan speed remain unchanged.
[0134] In this embodiment of the invention, during dehumidification in a well-sealed space, the dehumidification effect is adjusted based on the current humidity information. If the humidity does not meet the second preset condition, a fourth instruction is generated to dynamically adjust the frequency of the outdoor unit until the corresponding humidity meets the second preset condition, at which point the outdoor unit maintains the adjusted frequency. This allows for real-time monitoring of the humidity within the space and dynamic adjustment of the outdoor unit's frequency, improving the control accuracy of cooling and dehumidification while saving electricity.
[0135] Figure 3 This is a schematic diagram of the control device for air conditioning dehumidification provided by the present invention. Based on any of the above embodiments, such as... Figure 3 As shown, the air conditioning dehumidification control device provided in this embodiment of the invention includes: a humidity acquisition module 310, a humidity reduction acquisition module 320, and a first control module 330, wherein:
[0136] The humidity acquisition module 310 is used to receive the current humidity information in the room.
[0137] The humidity reduction acquisition module 320 is used to acquire the humidity reduction based on current humidity information and historical humidity information.
[0138] The first control module 330 is used to send a first command to the outdoor unit when the humidity drop is less than a first threshold, so as to control the outdoor unit to increase its frequency.
[0139] Among them, historical humidity information is determined based on humidity information collected in each historical period.
[0140] Specifically, the humidity acquisition module 310, the decrease acquisition module 320, and the first control module 330 are electrically connected in sequence.
[0141] After the air conditioner starts the dehumidification mode, the humidity acquisition module 310 receives the current humidity information collected by the sensing module during the current working cycle.
[0142] The humidity reduction acquisition module 320 uses the current humidity information acquired by the humidity acquisition module 310 and the stored historical humidity information to calculate the humidity reduction.
[0143] The first control module 330 compares the humidity reduction obtained by the reduction acquisition module 320 with a pre-set first threshold. The comparison results include: comparison success and comparison failure.
[0144] Successful comparison occurs when the humidity drop is less than the first threshold, indicating that the fresh air volume exceeds or approaches the air conditioning processing volume, meaning that the air conditioning system is in a poorly sealed space. In this case, the air conditioning dehumidification control device sends the first instruction to the outdoor unit.
[0145] The outdoor unit receives and responds to the first instruction, and starts to increase the frequency based on the default frequency of the dehumidification mode of the air conditioning system, increasing the cooling capacity so that the amount of cold air processed by the air conditioner exceeds the amount of fresh air, thereby achieving cooling and dehumidification.
[0146] If the comparison fails, it means that the humidity reduction is not less than the first threshold.

It will not be described again here.
[0163] This invention calculates the humidity drop based on the current indoor humidity information and historical humidity information.

Figure 4 As shown, the air conditioning dehumidification control system provided in this embodiment of the invention includes an air conditioning dehumidification control device 410, and also includes a sensing module 420 and a power supply module 430.

Based on the humidity drop rate, it sends a first command to the outdoor unit to control the outdoor unit to increase its frequency. This enables the analysis of air leakage status based on the ambient humidity and the adaptive adjustment and balance of cooling and dehumidification capacity. This ensures that the dehumidification function of the air conditioning system is not affected by the airtightness of the environment, improves the control accuracy of cooling and dehumidification, and enhances the dehumidification effect.

[0178] Specifically, the power supply for all humidity sensors 421 in the sensing module 420 comes from the ceiling of the current space. A layer of energy storage lithium battery panel is placed over the ceiling to serve as the power module 430. Each humidity sensor 421 is wirelessly charged under the coverage of the power module 430 to ensure uninterrupted power supply. At the same time, the power module 430 can also be continuously charged using outdoor suspended solar photovoltaic panels.
[0179] The embodiments of the present invention utilize the radio electromagnetic effect between the power module 430 and the sensing module 420 to perform passive charging, which can avoid circuit entanglement and extend the service life of the device.
