[0034] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described below with reference to the accompanying drawings, in which:

[0035] Figure 1 A schematic diagram of a combined air-conditioning device provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0036] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0037] The present invention proposes an embodiment of a combined air conditioning device, specifically, Figure 1 shown, including:

[0038] Air conditioning box 1;

[0039] A water pool 4 fixed to the bottom of the air conditioning box 1;

[0040] An upper rotating roller 21 is provided inside the air conditioning box 1 and fixed to the side wall of the air conditioning box 1;

[0041] A driving mechanism provided on the side wall of the air conditioning box 1;

[0042] A lower rotating roller 22 fixed to the driving mechanism, the lower rotating roller 22 is located below the upper rotating roller 21;

[0043] The filter screen 3 is fixed at both ends on the upper rotating roller 21 and the lower rotating roller 22;

[0044] A first pressure sensor 61 and a second pressure sensor 62 are provided on the side wall of the air conditioning box 1 and located on both sides of the filter 3;

[0045] A flushing motor 7 is provided outside the air conditioning box 1 and is connected to the air conditioning box 1 through a pipe 8;

[0046] The pipe 8 is connected to the pool 4 and a nozzle 9 is provided on the pipe 8;

[0047] The controller 10 is arranged outside the air-conditioning box 1 , and is electrically connected to the first pressure sensor 61 and the second pressure sensor 62 .

[0048] Specifically, after the air enters the air-conditioning box 1, it passes through the outer polyester fiber coarse-effect layer and the middle glass fiber HEPA layer of the filter 3 in sequence, and the particulate matter is intercepted, thereby achieving the purpose of dust removal.

[0049] The upper rotating roller 21 and the lower rotating roller 22 are arranged parallel to each other. Both are made of 304 stainless steel and covered with a corrosion-resistant rubber layer. They drive the filter 3 in a circular motion. The filter 3 has a multi-layer composite structure, with an outer polyester fiber coarse-effect layer (intercepting particles ≥ 5 μm), a middle glass fiber HEPA layer (intercepting particles ≥ 0.3 μm), and an inner hydrophilic non-woven fabric layer (capillary water absorption rate ≥ 200 g / m2). The ring-shaped design matches the circumference of the rollers and achieves continuous rotation through a gear drive (adjustable speed of 0.5-2 r / min).

[0050] Four nozzles 9 are located on the inner wall of the air conditioning housing 1, located in front and behind the filter 3, spaced 0.5 meters apart. The nozzles 9 have a spray pressure of 0.5-1.2 MPa and an adjustable spray angle of 30° to 60°. When the start-up conditions are met, the nozzles 9, driven by the flushing motor, automatically start spraying water to clean the filter 3.

[0051] A driving mechanism is provided on the inner walls on both sides of the air conditioning box 1. The driving mechanism includes a lifting mechanism 51 fixed to the inner wall of the air conditioning box 1. The lower end of the lifting mechanism 51 is located inside the water pool 4. The lower rotating roller 22 slides along the lifting mechanism 51.

[0052] Through the first belt 52 and the driving motor 53 of the upper rotating roller 21;

[0053] The upper rotating roller 21 and the lower rotating roller 22 are connected by a second belt 54 .

[0054] The lower half of the filter 3 is immersed in the water pool 4. The hydrophilic nonwoven fabric within the filter 3 absorbs water evenly through capillary action, raising the humidity of the air passing through the moistened filter 3 to the set value. The lower rotating roller 22 slides up and down on the lifting mechanism 51, adjusting the depth of the filter 3 immersed in the water, and thus the humidity of the air after passing through the filter 3, based on the actual humidity and the set humidity.

[0055] A first pressure sensor 61 and a second pressure sensor 62 located on either side of the filter 3 monitor the pressure on both sides of the filter 3 in real time. When the pressure difference between the two pressure sensors is ≥1000 Pa, the cleaning process is triggered. The controller 10 controls the flushing motor 7 to start, and water from the water tank 4 is pumped through the nozzle 9 to flush the filter 3. The spray angle of the nozzle 9 can be adjusted between 30° and 60° to achieve full coverage of the filter 3 during the spraying. The sprayed water flows into the water tank 4 for recycling.

[0056] A water quality monitor 41 is provided at the bottom of the water tank 4 and is electrically connected to the controller 10. A sewage discharge solenoid valve 42 is provided at the bottom of the air conditioning cabinet 1. The sewage discharge solenoid valve 42 extends into the interior of the water tank 4 and is electrically connected to the water quality monitor 41. A liquid level sensor 43 is provided at the bottom of the water tank 4 and is electrically connected to the controller 10. A water replenishment solenoid valve 44 is provided on the side wall of the air conditioning cabinet 1 and extends into the interior of the water tank 4 and is electrically connected to the water quality monitor 41. Based on the sensor data, the controller 10 performs dynamic speed regulation, humidity closed-loop PID control, and self-cleaning optimization logic.

[0057] When the TDS value measured by water quality monitor 41 is ≤500ppm, the water in pool 4 is reused, and liquid level sensor 43 ensures a stable liquid level. When the TDS value exceeds 500ppm, drain solenoid valve 42 opens to drain the wastewater from pool 4. When the liquid level in pool 4 measured by liquid level sensor 43 is less than 10cm, controller 10 receives a water replenishment signal and opens solenoid valve 44 to replenish softened water into pool 4. Liquid level sensor 43 provides real-time feedback on the water level. When the water level reaches 15cm, solenoid valve 44 closes. A water level exceeding 25cm (overly high) triggers an alarm, suspending system operation.

[0058] Among them, the power of the flushing motor 7 is set to 0.75kW and the protection level is IP65.

[0059] The caliber of the sewage discharge solenoid valve 42 is DN50, the pressure resistance is 1.6MPa, the response time is ≤1s, and it supports automatic emptying of sewage to prevent impurity deposition.

[0060] The first pressure sensor 61 and the second pressure sensor 62 have a measuring range of 0-2000 Pa and an accuracy of ±1% FS, and dynamically monitor the clogging status of the filter.

[0061] The water quality monitor 41 monitors the TDS value (0-1000ppm) and pH value (5-9) to ensure that the humidification water quality meets the standards.

[0062] Pipe 8 is made of UPVC material with a smooth inner wall to avoid sewage residue.

[0063] Liquid level sensor 43 monitors the water level of pool 4 in real time, ensuring that the liquid level in pool 4 remains stable at 10-15 cm. Liquid level sensor 43 has a measuring range of 0-30 cm, an accuracy of ±1 mm, an output signal of 4-20 mA analog, and an IP68 protection rating (waterproof and dustproof).

[0064] The water supply solenoid valve 44 automatically replenishes soft water to the pool 4 based on the data from the liquid level sensor 43. The water supply solenoid valve 44 has a diameter of DN40, a pressure resistance of 1.0 MPa, a response time of ≤2 seconds, a material of brass valve body and food-grade silicone sealing ring, and a power supply of DC 24V (low-power design).

[0065] The combined air-conditioning device of this embodiment further includes: a laser sensor 11 arranged on the top of the air-conditioning box 1 and a temperature and humidity sensor 12 arranged inside the air-conditioning box 1 .

[0066] Laser sensor 11 uses a PM2.5 laser sensor with an accuracy of ±5 μg / m³, a range of 0-1000 μg / m³, and a data sampling frequency of 1 Hz. It is used to provide real-time feedback to controller 10. Temperature and humidity sensor 12 has an accuracy of ±1% RH and is used to detect the temperature and humidity inside the air conditioner in real time and provide feedback to controller 10.

[0067] The control logic of the combined air conditioning device of this embodiment is as follows:

[0068] (1) Dynamic speed regulation: When the PM2.5 concentration increases by 50 μg / m³, the speed of the upper rotating roller 21 and the lower rotating roller 22 increases by 0.2 r / min (upper limit 2 r / min) to ensure dust removal efficiency; when the concentration is lower than 20 μg / m³, the speed is reduced to 0.5 r / min to save energy.

[0069] (2) Humidity closed-loop control: The immersion depth of filter 3 (10-15 cm) is adjusted through the PID algorithm, and the response time is ≤30s.

[0070] (3) Automatic cleaning: When the pressure difference before and after the filter 3 is greater than 1000 Pa, the flushing motor 7 starts, pumping water from the bottom pool 4 into the nozzle 9 through the self-cleaning pipe 8 to clean the filter 3.

[0071] (4) Automatic sewage discharge: When the TDS value of the water quality monitor is greater than 500, the sewage discharge solenoid valve opens and the sewage is discharged.

[0072] (5) Water circulation in the bottom pool:

[0073] When the TDS value measured by water quality monitor 41 is ≤500ppm, the water in pool 4 is reused, and liquid level sensor 43 ensures a stable liquid level. When the TDS value exceeds 500ppm, drain solenoid valve 42 opens to drain the wastewater from pool 4. When the liquid level in pool 4 measured by liquid level sensor 43 is less than 10cm, controller 10 receives a water replenishment signal and opens solenoid valve 44 to replenish softened water into pool 4. Liquid level sensor 43 provides real-time feedback on the water level. When the water level reaches 15cm, solenoid valve 44 closes. A water level exceeding 25cm (overly high) triggers an alarm, suspending system operation.

[0074] In summary, the combined air-conditioning device of this embodiment modularizes the humidification and dust removal functions, effectively reducing the system operation energy consumption, while simplifying the pipeline layout, reducing airflow resistance, and improving energy efficiency; the filter adopts hydrophilic non-woven fabric humidification technology, which absorbs water evenly through capillary action, avoiding the problem of traditional high-pressure atomization carrying impurities, with high dust removal efficiency, and the humidification water quality is monitored in real time through TDS and pH value to ensure air cleanliness; the controller is based on a closed-loop PID algorithm with multiple sensors to dynamically adjust the filter speed and immersion depth to achieve "dust removal and humidification on demand"; self-cleaning system High-pressure spray cleaning is triggered by the pressure differential threshold, combined with the sewage solenoid valve and water quality circulation logic to reduce the frequency of manual intervention; the filter uses a 304 stainless steel roller body and a corrosion-resistant rubber layer, which greatly extends its service life; the liquid level sensor (IP68 protection) and the ultra-high liquid level alarm mechanism (>25cm triggers shutdown) provide dual protection to avoid the risk of water overflow; UPVC self-cleaning pipes and food-grade sealing materials eliminate sewage residue and corrosion risks, greatly reducing the system failure rate; the water circulation design of the bottom pool greatly reduces water resource waste, effectively reduces operating costs, and improves economic efficiency.
