[0030] Air quality in the target area of ​​an air conditioning system can be affected by various factors, making it difficult to guarantee air quality. In poor air quality conditions, users will experience noticeable discomfort. Therefore, how to use air conditioning systems to purify the air and improve air quality in the target area has become an urgent problem to be solved.

[0031] In recent years, with the rapid development of materials science, electronic technology, and environmental science, air purification technology has made significant progress. In particular, the application of ion generation technology has provided a new solution for improving indoor air quality. Ion generators can simulate the waterfall and forest effects in nature, effectively neutralizing harmful substances in the air, such as bacteria, viruses, allergens, and formaldehyde, by generating beneficial ions such as negative oxygen ions and water-based hydroxyl ions, thereby significantly improving indoor air quality.

[0032] However, most ion generators currently on the market are standalone devices and have not yet been widely integrated into air conditioning and other air conditioning equipment. Furthermore, some integrated ion generators suffer from low ion generation efficiency, high energy consumption, and high maintenance costs, making it difficult to meet the market's demand for efficient, energy-saving, and convenient air purification equipment.

[0033] Currently, the closest existing technology utilizes methods such as high-voltage discharge to generate negative ions to improve indoor air quality. However, existing air conditioning devices that integrate ion generators primarily rely on generating a single type of negative oxygen ion to improve indoor air quality. However, this single ion type has relatively limited air purification effects and cannot comprehensively address multiple needs such as allergen removal, sterilization, disinfection, formaldehyde removal, and odor elimination. In contrast, the waterfall and forest effects in nature involve multiple types of ions, and these ions work synergistically to purify the air more efficiently.

[0034] To address the above problems, this application provides an air conditioning system 100.

[0035] Please see Figure 1 The air conditioning system 100 provided in this application includes an outdoor unit 10 and an indoor unit 20. The outdoor unit 10 includes a first heat exchanger 11, and the indoor unit 20 is provided with a second heat exchanger 21, a housing 22, and an ion generator 23. The second heat exchanger 21 is installed inside the housing 22 and connected to the first heat exchanger 11. The housing 22 has an air inlet 221 and an air outlet 222. The ion generator 23 is connected to the housing 22, and the output port 2311 of the ion generator 23 faces the air outlet 222. The ion generator 23 is used to generate various types of ions.

[0036] Specifically, an air conditioning system 100 refers to equipment that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow rate of the indoor air in a building or structure. The type of air conditioning system 100 can vary, including multi-split air conditioning systems 100 and single-unit air conditioning systems 100; no specific limitation is made here. The indoor unit 20 is one of the core components of the air conditioning system 100 responsible for air handling, including heating and cooling. It is typically installed on walls, ceilings, floors, or hung on windows, and has multiple functions such as air filtration, circulation, dehumidification, heating, and cooling. The outdoor unit 10 is typically installed on the ground or on a mounting bracket and is responsible for discharging heat generated indoors into the outdoor air. It achieves heat exchange and cooling / heating functions through the circulation of refrigerant and heat transfer.

[0037] Indoor unit 20 and outdoor unit 10 work together to achieve cooling or heating. Outdoor unit 10 includes a first heat exchanger 11, and indoor unit 20 includes a second heat exchanger 21. The first heat exchanger 11 and the second heat exchanger 21 are connected by pipes, allowing refrigerant to flow between the first heat exchanger 11, the pipes, and the second heat exchanger 21. When the air conditioning system 100 is used for cooling, the refrigerant absorbs heat from the indoor air in the second heat exchanger 21, and then flows through the pipes to the first heat exchanger 11. The refrigerant in the first heat exchanger 11 can dissipate the absorbed heat to the outside, achieving the purpose of cooling. When the air conditioning system 100 is used for heating, the first heat exchanger 11 and the second heat exchanger 21 play the opposite role; the refrigerant absorbs heat from the outdoor air into the indoor unit 20, achieving the purpose of heating.

[0038] The housing 22 is a structure with a cavity for accommodating other components. Other components of the indoor unit 20 can be installed inside the housing 22. The housing 22 can be used to isolate other components of the indoor unit 20 from the outside world to prevent them from being easily damaged by external forces and to prevent external impurities, such as dust, from entering the other components and affecting their normal operation.

[0039] The ion generator 23 is a device that uses a high-voltage transformer to boost the power frequency voltage to the required voltage, thereby generating positive or negative ions and releasing them into the surrounding air. The ion generator 23 can employ various technologies to produce ions of different types, thus improving air purification efficiency. For example, the ion generator 23 can utilize corona ionization technology, generating corona discharge through high-voltage current to ionize air molecules, forming positive and negative ions. The ion generator 23 can also utilize alpha ionization technology, using radioactive isotopes (such as polonium-210) as the ionization source. When these isotopes collide with air, they transfer electrons, turning neutral air molecules into negative ions while simultaneously becoming positive ions themselves. Alternatively, electron avalanche technology can be used to electrolyze water to generate water-based hydroxyl ions. Different types of ions have different purification effects. For example, negative ions can combine with smoke and dust particles in the air, causing them to become statically charged and settle, thus purifying the air. Furthermore, negative ions can combine with oxygen in the air to form ozone, which has a certain bactericidal effect. The principle behind positive ion air purification is that positively charged ions capture, adsorb, condense, and settle dust, bacteria, viruses, and other microorganisms in the air. Simultaneously, they activate oxygen molecules, generating reactive oxygen species, which break the chemical bonds of organic pollutants, rendering them inactive and harmless. Water-based hydroxyl ions can disrupt the integrity of the protein and lipid molecules of bacteria and viruses, inhibiting their transport and metabolism, thereby achieving thorough sterilization and disinfection.

[0040] The second heat exchanger 21 is located inside the housing 22. The housing 22 has an air inlet 221 and an air outlet 222. Air from the target location of the air conditioning system 100 enters the housing 22 through the air inlet 221 to exchange heat with the second heat exchanger 21. The heat-exchanged air flows out through the air outlet 222 and reaches the target location to regulate the temperature of the target location. An ion generator 23 is installed in the housing 22, with its output port 2311 facing the air outlet 222. The ion generator 23 can be installed inside the housing 22 in an area near the air outlet 222 (e.g., ...). Figure 1 ) or mounted on the outer surface of housing 22 near air outlet 222 (e.g. Figure 4 The area to which the ion generator 23 can be located is not limited, as long as at least one output port 2311 of the ion generator 23 faces the air outlet 222. In this way, the ions generated by the ion generator 23 can be injected into the air about to flow out of the air outlet 222 or the air that has already flowed out of the air outlet 222, ensuring that the air is sufficiently purified before entering the target area. This allows the ions to flow with the air discharged from the indoor unit 20 to the entire target area, completing the air purification of the target area. Because the ion generator 23 can generate different types of ions, its air purification effect is superior.

[0041] Meanwhile, the air conditioning system 100 also includes a controller, which can be used to control the operation of the outdoor unit 10, the indoor unit 20, and the ion generator 23. Therefore, users can directly control the operation of the ion generator 23 through the air conditioner remote control, which facilitates user operation.

[0042] The outdoor unit 10 of the air conditioning system 100 according to this application includes a first heat exchanger 11, and the indoor unit 20 includes a second heat exchanger 21, a housing 22, and an ion generator 23. The first heat exchanger 11 and the second heat exchanger 21 are connected. The second heat exchanger 21 is located inside the housing 22. The housing 22 has an air inlet 221 and an air outlet 222. The output port 2311 of the ion generator 23 faces the air outlet 222. The ion generator 23 is used to generate various types of ions. Air from the target location can enter the housing 22 through the air inlet 221 and exchange heat with the second heat exchanger 21. After heat exchange, the air re-enters the target location through the air outlet 222. The output port 2311 of the ion generator 23 faces the air outlet 222, so that the ions generated by the ion generator 23 can be injected into the air about to enter the target location, thereby allowing the ions to flow throughout the entire location with the air discharged from the indoor unit 20, completing the purification of the air in the target location. Thus, this application integrates an ion generator 23 that can generate multiple ions on the indoor unit 10, so that the indoor unit 23 can use multiple ions for air purification during operation, thereby improving the air purification effect and ensuring better air quality in the target location.

[0043] Please see Figure 1 and Figure 5 In some embodiments, the ion generator 23 includes a housing 231 and a plurality of ion generating components 232. The ion generating components 232 are installed inside the housing 231. The output port 2311 of the ion generator 23 passes through the housing 231. The ions generated by the ion generating components 232 leave the ion generator 23 from the output port 2311. The ions generated by the plurality of ion generating components 232 are of different types.

[0044] Specifically, the ion generating component 232 is the element in the ion generator 23 that generates ions. Each ion generating component 232 uses a different ion generating technology, resulting in different types of ions generated by different ion generating components 232. The ion generating component 232 is installed inside the housing 231, and the output port 2311 of the ion generator 23 passes through the housing 231. The ions generated by the ion generating component 232 leave the ion generator 23 from the output port 2311 and are injected into the air that is about to enter the target area, so that the ions can flow with the air discharged from the indoor unit 20 to the entire target area, thereby completing air purification.

[0045] In some embodiments, the ion generator 23 also includes a fan installed inside the housing 22, with the output end of the fan facing the output port 2311 of the ion generator 23, so that the fan can drive ions to move to the output port 2311 of the ion generator 23, thereby accelerating the movement rate of the ions and ensuring that the generated ions can quickly move to the target location.

[0046] Please see Figure 1 and Figure 5 In some embodiments, the ion generating component 232 includes a first ion generating module 2321 and a second ion generating module 2322. The first ion generating module 2321 includes an avalanche electrode that electrolyzes water to generate water-based hydroxyl ions when energized. The second ion generating module 2322 includes a positive discharge electrode and a negative discharge electrode that electrolyzes air to generate negative oxygen ions and positive hydrogen ions when energized.

[0047] Specifically, the first ion generating module 2321 includes an avalanche electrode, which electrolyzes water to generate water-based hydroxyl ions when energized. The avalanche electrode can capture water molecules from the air; for example, by designing the first ion generating module 2321 to achieve a Peltier effect, the air's moisture is collected, cooled, and condensed, adhering to the surface of the avalanche electrode. Alternatively, the first ion generator 23 can also be equipped with a water storage device connected to the avalanche electrode, which can supply water to the avalanche electrode so that water adheres to its surface. When energized, a strong electric field is generated in the first ion generating module 2321, under which the avalanche electrode undergoes a tip discharge reaction. At this time, initial electrons are generated near the avalanche motor. Through collision ionization, the number of electrons increases exponentially, forming an electron avalanche effect and generating water-based hydroxyl ions (·OH). The water-based hydroxyl ions combine with water molecules and are released into the air in the form of atomization diffusion and aerosol. Then, the water-based hydroxyl ions can flow to the target location through the output port.

[0048] The second ion generating module 2322 includes a positive discharge electrode and a negative discharge electrode. When energized, the positive discharge electrode electrolyzes air to generate negative oxygen ions and positive hydrogen ions. When energized, a strong electric field is generated in the first ion generating module 2321. Under the influence of this strong electric field, the avalanche electrode undergoes a tip discharge reaction. The positive discharge electrode can react with small-diameter water molecules in the air to generate positive hydrogen ions (H+), and the negative discharge electrode can react with oxygen in the air to generate negative oxygen ions (O2-).

[0049] Thus, the ion generating component 232 can simultaneously generate water-based hydroxyl ions, positive hydrogen ions, and negative oxygen ions. These ions provide various purification effects. Negative and positive ions can cause allergens such as PM2.5 dust, mold, and pollen to acquire positive and negative charges, leading to adsorption, aggregation, and sedimentation, thus reducing the concentration of allergens in the air. The active factors, such as water-based hydroxyl ions and negative oxygen ions, can capture hydrogen from organic allergens, combining with them to form water, thereby decomposing or destroying the allergens' activity. These active factors can also disrupt the integrity of the protein and lipid molecules of bacteria and viruses, inhibiting their transmission and metabolism, thereby achieving thorough sterilization and disinfection. Furthermore, upon contact with formaldehyde and odors, these active factors can react with the R-groups (represented by H-groups) in their molecular structure, decomposing them into non-toxic and harmless substances such as H2O and CO2. In summary, the ion generating component 232 can achieve the functions of resisting allergens, sterilizing and disinfecting, and removing odors, thereby enabling the ion generator 23 to achieve multiple purification effects on the target location.

[0050] Please see Figure 1 and Figure 5 In some embodiments, the first ion generating module 2321 includes a first protective shell 23211, within which an avalanche electrode is located to protect the avalanche electrode. The first protective shell 23211 has an inlet 23212 and an outlet. Air enters the first protective shell 23211 through the inlet 23212 to react with the avalanche electrode, thereby generating water-based hydroxyl ions. The water-based hydroxyl ions then exit the first ion generating module 2321 through the outlet of the first protective shell 23211.

[0051] The second ion generating module 2322 includes a second protective shell 23221. A positive discharge electrode and a negative discharge electrode are located inside the second protective shell 23221 to protect them. The second protective shell 23221 has an inlet 23222 and an outlet 23223. Air enters the second protective shell 23221 through the inlet 23222 to react with the positive and negative discharge electrodes, thereby generating positive hydrogen ions and negative oxygen ions. The positive hydrogen ions and negative oxygen ions then leave the second ion generating module 2322 through the outlet 23223 of the second protective shell 23221.

[0052] The output port 23223 of the first protective shell 23211 is connected to the input port 23222 of the second protective shell 23221, allowing the water-based hydroxyl ions generated by the first ion generating module 2321 to enter the second protective shell 23221. During the electrolysis of water, the water-based hydroxyl ions at the positive discharge electrode can catalyze the decomposition of water molecules, thereby increasing the generation rate of hydrogen ions.

[0053] In some embodiments, the first protective shell 23211 includes a first output port 23213 and a second output port 23214. The first output port 23213 of the first protective shell 23211 is connected to the input port 23222 of the second protective shell 23221, and the second output port 23214 of the first protective shell 23211 is directly and only connected to the internal space of the outer shell 231 of the ion generator 23, that is, the second output port 23214 is not directly connected to the input port 23222 of the second protective shell 23221. In this way, of the water-based hydroxyl ions generated by the first ion generating module 2321, a portion moves directly to the outer shell 231 and then to the output port 2311 of the ion generator 23, thereby accelerating the output efficiency of the water-based hydroxyl ions. The other portion enters the second protective shell 23221 so that these water-based hydroxyl ions can be used to catalyze the reaction of the second ion generating module 2322, thereby improving the reaction efficiency of the second ion generating module 2322.

[0054] In other embodiments, the first protective shell 23211 has only one output port, and the output port of the first protective shell 23211 is connected to the input port 23222 of the second protective shell 23221, so that the water-based hydroxyl ions generated by the first ion generating module 2321 can enter the second protective shell 23221 and catalyze the decomposition of water molecules, thereby increasing the generation rate of hydrogen ions.

[0055] Thus, the second ion generating module 2322 utilizes the high-energy electrons generated by the first ion generating module 2321 to catalyze the decomposition of water molecules, generating the desired ions. Because the catalytic effect of high-energy electrons is stronger, the second ion generating module 2322 can more efficiently promote the decomposition reaction of water molecules, thereby generating more ions. Existing technologies typically employ high-voltage discharge technology, which usually acts directly on air or water molecules, resulting in relatively low catalytic efficiency.

[0056] Please see Figure 1 and Figure 4 In some embodiments, an air supply channel is formed between the air inlet 221 and the air outlet 222 inside the housing 22, the second heat exchanger 21 is located in the air supply channel, the ion generator 23 is installed on the outer surface of the housing 22, and the distance between the ion generator 23 and the air outlet 222 is less than a preset distance threshold, or the ion generator 23 is located in the air supply channel and is located upstream of the air outlet 222 in the wind direction.

[0057] Specifically, an air supply channel is formed inside the casing 22, with an air inlet 221 and an air outlet 222 connected to its two ends. After entering the casing 22 through the air inlet 221, the air moves along the air supply channel until it reaches the air outlet 222, thus reaching the target location. The second heat exchanger 21 is located inside the air supply channel, allowing heat exchange between the air and the second heat exchanger 21 as the air moves within the air supply channel.

[0058] There are multiple ways to set the ion generator 23, as long as the air discharged from the indoor unit 20 contains ions generated by the ion generator 23.

[0059] Please combine Figure 1 In one embodiment, the preset distance threshold is the maximum distance between the ion generator 23 and the air outlet 222 when a large amount of ions generated by the ion generator 23 can be injected into the air flowing out of the air outlet 222. The ion generator 23 is installed on the outer surface of the housing 22, and the distance between the ion generator 23 and the air outlet 222 is less than the preset distance threshold. This can be understood as the ion generator 23 being installed in the area near the air outlet 222 on the outer surface of the housing 22, with the output port 2311 of the ion generator 23 facing the air outlet 222. In this way, the ion generator 23 injects a large amount of ions into the air flowing out of the air outlet 222, so that the ions can flow with the air flowing out of the air outlet 222 to the entire target area, thereby improving the air purification effect of the ions on the target area.

[0060] Please combine Figure 4 In another embodiment, the ion generator 23 is located in the air supply channel and upstream of the air outlet 222, so that the air inside the housing 22 needs to pass through the ion generator 23 before flowing to the air outlet 222. In this way, the ion generator 23 injects ions into the air before the air flows out of the air outlet 222, so that the ions can flow with the air flowing out of the air outlet 222 to the entire target area.

[0061] With the ion generator 23 located in the air supply duct, it can be installed near the air inlet 221, so that the air entering through the air inlet 221 is immediately injected with ions. The ions can then flow with the air in the air supply duct, facilitating the disinfection of the indoor unit 20. When the air flows from the air outlet 222 to the target area, the ions also flow with the air to the target area. In this way, the ions generated by the ion generator 23 can simultaneously purify and disinfect the air in both the indoor unit 20 and the target area. The ion generator 23 can also be installed near the air outlet 222 to ensure a sufficient number of ions enter the target area, thereby ensuring the air purification effect in the target area.

[0062] Please see Figure 1 In some embodiments, there are multiple ion generators 23, such as two, five or seven, in order to increase the ion concentration generated by the ion generators 23, thereby improving the air purification effect of the air conditioning system 100 on the target location.

[0063] Multiple ion generators 23 are installed on at least one of the outer surface of the housing 22 or in the air supply duct. Specifically, in one embodiment, multiple ion generators 23 can be uniformly installed on the outer surface of the housing 22, and the distance between each ion generator 23 and the air outlet 222 is less than a preset distance threshold. That is, multiple ion generators 23 are all installed in the area of ​​the outer surface of the housing 22 near the air outlet 222 to ensure that a sufficient number of ions enter the target area, thereby improving the air purification effect of the air conditioning system 100. In another embodiment, multiple ion generators 23 can be uniformly installed in the air supply duct, and each ion generator 23 is located upstream of the air outlet 222 in the airflow direction, so as to facilitate the ion purification and disinfection of the indoor unit 20 and the target area. In another embodiment, among the multiple ion generators 23, some ion generators 23 are installed in the area near the air outlet 222 on the outer surface of the housing 22, and some ion generators 23 are installed in the air supply duct. This ensures that the ion generators 23 can also disinfect the indoor unit 20, and also ensures that a sufficient number of ions enter the target area, thereby facilitating the improvement of the purification effect of the air conditioning system 100.

[0064] Please see Figure 4 In some embodiments, at least two sides of the outer surface of the ion generator 23 are provided with output ports 2311, wherein at least one output port 2311 of the ion generator 23 faces the air outlet 222. For example, the outer surface of the ion generator 23 includes four sides and a top surface, and output ports 2311 are installed on all four sides and the top surface. Alternatively, the sides and top surface of the ion generator 23 facing the air outlet 222 are provided with output ports 2311, or the two sides closest to the air outlet 222 are provided with output ports 2311. In this way, ions generated in the ion generator 23 can flow out through the output ports 2311 of multiple ion generators 23, thereby flowing to the target location, improving the ion flow efficiency, ensuring that ions can quickly flow to the target location, and completing air purification.

[0065] Please see Figure 2 and Figure 3 In some embodiments, there are one or more air outlets 222, and each air outlet 222 is provided with an ion generator 23 on the outer surface of the corresponding housing 22 or in the air supply channel.

[0066] Specifically, the number of air outlets 222 may vary between different indoor units 20, for example... Figure 2For example, if an indoor unit 20 is a multi-split indoor unit with one air outlet, then the number of air outlets 222 is one. Figure 3 One indoor unit 20 is a dual-outlet multi-split indoor unit, in which case there are two air outlets 222. Therefore, the number of air outlets 222 of the indoor unit 20 can be one or more, such as one, two, four, or five. Each air outlet 222 is equipped with a corresponding ion generator 23, that is, each air outlet 222 is equipped with a dedicated ion generator 23. For example, all ion generators 23 are located on the outer surface of the housing 22, each ion generator 23 has a corresponding air outlet 222, and the distance between each ion generator 23 and its corresponding air outlet 222 is less than a preset distance threshold. As another example, all ion generators 23 are located in the air supply duct, each ion generator 23 has a corresponding air outlet 222, and each ion generator 23 is located upstream of its corresponding air outlet 222 in the airflow direction. In this way, it can be ensured that the air discharged from each air outlet 222 is injected with ions generated by the ion generator 23 before entering the target area, so that the ion generator 23 can flow to the target area with the air discharged from the air outlet 222, thereby improving the air purification effect of the air conditioning system 100.

[0067] Please see Figure 1 In some embodiments, the air conditioning system 100 includes an air detector (not shown) for detecting the current pollutant concentration in the target area of ​​the air conditioning system 100. If the current pollutant concentration is lower than a preset concentration threshold, the ion generator 23 is activated.

[0068] Specifically, air detectors can be used to monitor the concentration of pollutants in the air, such as inhalable particulate matter (e.g., PM10, PM2.5), formaldehyde (HCHO), or benzene (C6H6). The concentration of pollutants can characterize the air quality of a target location; understandably, the higher the concentration, the worse the air quality.

[0069] The air conditioning system 100 can be set with a preset concentration threshold, which is the minimum concentration of pollutants that would harm the human body and cause discomfort to the user. If the current pollutant concentration exceeds the preset threshold, it can be considered that the current pollutant concentration is too high, the air quality in the target area is poor, and the user will feel discomfort. In this case, the ion generator 23 can be activated to purify the air in the target area using ions generated by the ion generator 23, reducing the pollutant concentration and improving the air quality. Conversely, if the current pollutant concentration is below the preset threshold, the air quality in the target area is considered good, and the user does not feel significant discomfort; in this case, the ion generator 23 does not need to be activated.

[0070] Thus, the ion generator 23 is only turned on when the current pollutant concentration is below the preset concentration threshold and the air quality at the target location is poor. This ensures that the ion generator 23 can reduce the pollutant concentration at the target location in a timely manner when the pollutant concentration is high, and also prevents the ion generator 23 from running for a long time, thereby saving energy consumption of the ion generator 23.

[0071] Existing technologies also suffer from low ion generation efficiency, high maintenance costs, and low integration.

[0072] 1. Low ion generation efficiency: Some ion generators 23 use high-voltage discharge technology, which can generate a certain amount of ions, but the energy consumption is high and the ion generation efficiency is not stable enough. It is easily affected by environmental humidity, temperature and other factors, and the amount of ion generated is prone to fluctuation, making it difficult to guarantee a continuous and stable air purification effect.

[0073] 2. High maintenance costs: High-voltage discharge technology requires regular replacement of electrodes and other components, resulting in high maintenance costs and potential safety hazards. The ion generator 23 employing high-voltage discharge technology requires regular replacement of electrodes and other components, which not only increases maintenance costs but also may pose safety risks. Especially during prolonged use, the insulation performance of high-voltage components may deteriorate, increasing the risk of electric shock and fire.

[0074] 3. Low Integration: Currently, most air conditioning devices with integrated ion generators 23 on the market have the ion generator 23 as an add-on component, resulting in low integration with the main system. This affects the overall aesthetics and ease of use. This not only increases the size and weight of the device but also impacts its overall appearance and ease of installation. In modern home environments that prioritize space utilization and aesthetic design, this shortcoming is particularly pronounced.

[0075] In summary, this application can utilize the first ion generating module 2321 and the second ion generating module 2322 to generate water-based hydroxyl ions, positive hydrogen ions, and negative oxygen ions. Therefore, this application has the following advantages:

[0076] 1. Significantly improved air purification effect:

[0077] By integrating the ion generator 23, this application can simultaneously generate negative oxygen ions (O2-), water-based hydroxyl ions (·OH), and active positive ions (H+). These ions work synergistically to more comprehensively cover all aspects of air purification. Experimental data shows that compared with traditional devices that only generate negative oxygen ions, the air purification efficiency of this application is improved by approximately 30%, and the removal rate of harmful substances such as bacteria, viruses, allergens, and formaldehyde all reach over 90%, significantly improving indoor air quality.

[0078] 2. Enhanced ion generation efficiency and stability:

[0079] This application employs a unique combination of a first ion generating module 2321 and a second ion generating module 2322 to achieve efficient and stable ion generation. The first ion generating module 2321 can generate a large number of high-energy electrons (i.e., water-based hydroxyl ions) with low energy consumption. These electrons have higher energy density and a more concentrated energy distribution, allowing them to be more effectively utilized by the second ion generating module 2322. The second ion generating module 2322 then utilizes these high-energy electrons to efficiently catalyze the decomposition of water molecules, generating the desired ions. This combined technology not only improves ion generation efficiency but also reduces energy consumption and fluctuations, ensuring the stability of ion generation. In practical applications, the fluctuation range of ion generation is controlled within ±5%, far superior to the ±15% fluctuation range of traditional high-voltage discharge technology.

[0080] Meanwhile, the quantity and quality of electrons generated by the first ion generating module 2321 are relatively stable, allowing the second ion generating module 2322 to continuously and stably utilize these electrons for catalytic reactions. Therefore, the combination of the first and second ion generating modules 2321 reduces energy consumption and fluctuations, ensuring the stability of ion generation. In contrast, high-voltage discharge technology is easily affected by voltage fluctuations, electrode wear, and other factors, leading to significant fluctuations in ion generation. Traditional high-voltage discharge technology often generates large amounts of ozone and other byproducts while producing ions. These byproducts are not only harmful to human health but also affect air purification efficiency. The combination of the first and second ion generating modules 2321 reduces the generation of these byproducts because their catalytic reactions are more precise and controllable.

[0081] 3. Improved equipment integration and aesthetics:

[0082] The ion generator 23 of this application is cleverly integrated into the air outlet 222 of the indoor unit 20, which not only reduces the overall size and weight of the device but also enhances its aesthetic appeal. This compact design makes the indoor unit 20 easier to integrate with various interior design styles without affecting its basic function as an air conditioner. Furthermore, the integrated design simplifies installation and maintenance processes, reducing user operating costs.

[0083] 4. Reduced maintenance costs and security:

[0084] Because this application abandons traditional high-voltage discharge technology and adopts a safer and more reliable combination of electron avalanche (technology of the first ion generation module 2321) and electrocatalysis (technology of the second ion generation module 2322), it significantly reduces maintenance costs and safety hazards. Electronic components have a longer lifespan, reducing replacement frequency; simultaneously, the low-voltage operating environment reduces the risk of electric shock and fire. Experimental data shows that the maintenance cost of this application is approximately 20% lower than traditional equipment, and no safety incidents occurred throughout its entire service life.

[0085] 5. Significant socio-economic benefits:

[0086] From a socio-economic perspective, the promotion and application of this application will bring significant benefits. On the one hand, by improving indoor air quality, it will help improve people's living environment and health, and reduce diseases and medical expenses caused by air pollution. On the other hand, the efficient and energy-saving design is in line with the current green and low-carbon development trend, and will help promote the transformation, upgrading and sustainable development of related industries.
