[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0019] like Figures 1-6 As shown, an ultra-thin window air conditioner according to one embodiment of the present invention includes a housing 1. A control panel 18 is provided on the surface of the housing 1, and the control panel 18 is used to control the electrical components inside the housing 1. A condensate collector 8 is provided in the middle of the housing 1, which divides the interior of the housing 1 into an upper cavity and a lower cavity, which are not connected to each other.

[0020] A compressor 2 is installed in the lower cavity. A first air inlet 101 and an air outlet 102 are provided on the front of the housing 1. A condenser 4 matching the air outlet 102 and a second fan 19 matching the first air inlet 101 are installed in the lower cavity. After the second fan 19 guides the air in through the first air inlet 101, the air passes through the condenser 4, allowing the condenser 4 to exchange heat with the air. After heat exchange, the air is discharged from the air outlet 102.

[0021] A first pipe 3 is fixedly connected between the input end of the compressor 2 and the output end of the condenser 4. A fourth pipe 13 is fixedly connected between the output end of the compressor 2 and the input end of the heat exchanger 6. A second pipe 5 is fixedly connected between the output end of the heat exchanger 6 and the input end of the condenser 4. A first fan 7 matching the heat exchanger 6 is installed on the housing 1, and a second air inlet 103 matching the first fan 7 is opened at the upper end of the housing 1.

[0022] like Figures 1-6 As shown, compressor 2 draws in refrigerant returning from condenser 4 through the first pipe 3 and compresses it. This process causes the pressure and temperature of the refrigerant to rise sharply, eventually turning it into a high-temperature, high-pressure gaseous refrigerant, providing power for the entire cycle. The high-temperature, high-pressure gaseous refrigerant discharged from compressor 2 passes through the heat exchanger 6 via the fourth pipe 13. Simultaneously, the first fan 7 operates, releasing heat from the gas to the outdoor air flowing through condenser 4. The condenser inside condenser 4 gradually condenses from a gaseous state into a high-pressure, room-temperature liquid due to cooling.

[0023] like Figures 1-6 As shown, the cooled refrigerant is transported to the condenser 4 through the second pipe 5. At this time, the second fan 19 draws in hot indoor air and forces it to blow across the condenser 4. In the condenser 4, the refrigerant absorbs the heat from the flowing air and rapidly evaporates, returning to a low-temperature, low-pressure gaseous state. The air, having lost heat, cools down and is blown back into the room, thus achieving the cooling purpose. The refrigerant, having absorbed heat, then returns to the compressor 2 through the first pipe 3, beginning a new cycle.

[0024] like Figures 1-5As shown, a first expansion valve 501 and a second expansion valve 502 are installed on the second pipeline 5, and a capillary tube 503 is installed between the first expansion valve 501 and the second expansion valve 502. The core function of the first expansion valve 501, the second expansion valve 502, and the capillary tube 503 is to throttle and reduce pressure. The refrigerant exiting the heat exchanger 6 is a medium-temperature, high-pressure liquid. In order for it to evaporate and absorb heat in the condenser 4, the pressure and temperature of the refrigerant must be reduced. The first expansion valve 501, the second expansion valve 502, and the capillary tube 503, through their narrow internal flow channels, greatly restrict the flow of the refrigerant, causing its pressure to drop sharply. According to the physical properties of the refrigerant, the pressure drop will lead to a decrease in its boiling point, causing a portion of the liquid refrigerant to evaporate rapidly, absorbing its own heat. This makes the refrigerant a low-temperature, low-pressure mist-like wet vapor when it leaves the first expansion valve 501, the second expansion valve 502, and the capillary tube 503, creating conditions for it to enter the condenser 4 and absorb heat.

[0025] like Figures 1-6 As shown, the housing 1 is provided with an air inlet 101 and an air outlet 102. The air inlet 101 serves as the air intake end during the start-up process of the second fan 19, and the air outlet 102 serves as the air outlet end during the start-up process of the second fan 19. The air blown out by the second fan 19 comes into contact with the condenser 4 and exchanges heat. After heat exchange, cold air is discharged from the air outlet 102.

[0026] In summary, in this embodiment, the main components of the window air conditioner, namely the compressor 2, heat exchanger 6, second fan 19, and condenser 4, are arranged on the housing 1 from bottom to top. Specifically, they can be fixed to the inside of the housing 1 by means of bolts or other detachable methods. Since the main components of the window air conditioner are arranged sequentially from bottom to top, the width of the window air conditioner can be greatly reduced. Under the premise of ensuring the integrity of the basic refrigeration cycle function, the problem of the large size of traditional window air conditioners is successfully solved.

[0027] like Figures 1-6 As shown, the condenser 4, compressor 2, and second fan 19 are located in the lower cavity, while the heat exchanger 6 and first fan 7 are located in the upper cavity. The condensate collector 8 can collect the condensate generated during the cooling process of the heat exchanger 6 and guide the condensate to the surface of the condenser 4, where the condensate forms a thin water film.

[0028] The function of the first fan 7 is to accelerate airflow. It not only quickly removes the sensible heat transferred due to temperature difference when the water film comes into contact with the air, but more importantly, it rapidly removes the saturated humid air generated by evaporation from the water film surface, making room for new, dry air. This maintains a large water vapor pressure difference, greatly accelerating the evaporation process. The first fan 7 also creates a negative pressure zone around the heat exchanger 6, further accelerating water film evaporation and enhancing heat transfer. Utilizing the heat absorption property of water evaporation allows for more effective control of the refrigerant temperature within the heat exchanger 6, providing design flexibility for further size reduction or noise reduction.

[0029] It is worth noting that after prolonged use, minerals in the water may form scale on the surface of condenser 4, which can easily affect heat dissipation. Therefore, it may be necessary to consider using softened water or regular cleaning. In addition, metal components that are exposed to humid environments for extended periods, such as condenser 4, require hydrophilic and corrosion-resistant coatings or materials to extend their lifespan.

[0030] Preferably, a baffle is provided between the compressor 2 and the condenser 4 to prevent condensate from dripping onto the compressor 2 during its descent, thus avoiding affecting the service life of the compressor 2.

[0031] like Figures 1 to 7 As shown, the condensate collector 8 includes a collection box 9. A third pipe 10 is fixedly connected to the lower end of the collection box 9. A valve 11 is fixedly connected to the third pipe 10. A distribution box 12, which matches the condenser 4, is fixedly connected to the end of the third pipe 10 away from the collection box 9. The collection box 9 can collect the condensate produced by the heat exchanger 6 and transport it to the distribution box 12 through the third pipe 10.

[0032] Specifically, multiple distribution heads 1202 are fixedly connected to the lower end of the distribution box 12. The output end of the distribution head 1202 is located at the upper end of the condenser 4 and is connected to the condenser 4. That is, condensate is discharged from the distribution head 1202 and sprayed on the surface of the condenser 4, further enhancing the cooling effect provided by the second fan 19 to the condenser 4.

[0033] like Figures 1 to 7 As shown, the collection box 9 is provided with a first inclined sidewall 901, and the diversion box 12 is provided with a second inclined sidewall 1201. The first inclined sidewall 901 and the second inclined sidewall 1201 are both for better collection of condensate, so that even a small amount of condensate can be sprayed onto the surface of the condenser 4 through the third pipe 10 and the diversion head 1202.

[0034] One specific solution to the problem of scale buildup on the surface of condenser 4 is to install a nanofiltration membrane or reverse osmosis membrane inside the collection box 9. By utilizing the tiny pores of the nanofiltration membrane or reverse osmosis membrane, calcium and magnesium ions can be intercepted and removed. This not only completely removes calcium and magnesium ions but also removes other impurities at the same time, preventing impurities from falling onto the surface of condenser 4 and causing condenser 4 to rust prematurely, thus avoiding affecting the service life of condenser 4.

[0035] In this embodiment, the working principle of the ultra-thin window air conditioner is as follows: After the equipment starts, compressor 2 draws in and compresses the low-temperature, low-pressure gaseous refrigerant from condenser 4, transforming it into a high-temperature, high-pressure state. This high-temperature, high-pressure refrigerant vapor then enters heat exchanger 6. First fan 7 accelerates the flow of outdoor air through the finned tubes of heat exchanger 6, carrying away heat from the refrigerant and causing it to condense into a high-pressure, room-temperature liquid. Next, the liquid refrigerant flows through a throttling device consisting of first expansion valve 501, capillary tube 503, and second expansion valve 502, causing a rapid drop in pressure and temperature, transforming it into a low-temperature, low-pressure mist mixture. Subsequently, the low-temperature, low-pressure refrigerant enters condenser 4. Second fan 19 drives indoor hot air through condenser 4, where the refrigerant absorbs heat from the air and evaporates into a gas, while the air is cooled and delivered indoors as cold air. The heat-absorbing low-temperature, low-pressure gaseous refrigerant finally returns to compressor 2 through fourth pipe 13, and a new cycle begins.

[0036] This embodiment includes at least the following beneficial effects; The core components, such as compressor 2, heat exchanger 6, condenser 4, and second fan 19, adopt a bottom-up vertical layout, effectively reducing the overall width of the air conditioner and making its structure more compact. This design significantly reduces the installation space requirements of window air conditioners, solving the problem of traditional window units being bulky and heavy, and better meeting the requirements of modern homes for both aesthetics and practicality.

[0037] An innovative condensate collector 8 is introduced. The condensate collector 8 guides condensate to the surface of the condenser 4, forming a water film. Utilizing the principle of heat absorption during water evaporation, this significantly enhances the heat dissipation effect of the condenser 4. This effectively lowers the refrigerant temperature, thereby improving the efficiency of the entire refrigeration system and creating conditions for the compressor 2 to operate under lower loads, thus reducing energy consumption and noise. The condensate generated during the refrigeration process is transformed from waste liquid into an effective resource for auxiliary heat dissipation, achieving internal recycling of water resources. This not only reduces the need for additional cooling media but also embodies a green and environmentally friendly design concept.

[0038] The condensate collector 8 divides the housing 1 into upper and lower non-communicating cavities, which helps isolate different functional areas and may reduce interference between internal components. Meanwhile, the inclusion of water treatment solutions such as nanofiltration or reverse osmosis membranes provides a preventative approach to addressing scaling on the condenser 4 surface after long-term operation, helping to extend equipment lifespan and maintain heat dissipation efficiency. Example

[0039] In practical use, it was found that although the size of the equipment was reduced and the heat exchange efficiency of the condenser 4 was improved by utilizing condensate, the size of the second fan 19 and the condenser 4 could be reduced, and the power of the second fan 19 could be decreased, thus reducing noise to some extent. However, for some noise-sensitive individuals, the noise level is still unacceptable. To solve the above problem, this embodiment adopts the following solution: like Figure 8 As shown, the housing 1 includes a first housing 20 and a second housing 21, with a cavity formed between the first housing 20 and the second housing 21. The cavity is filled with a noise-reducing medium 22, which can be an inert gas such as nitrogen, or a sound-insulating material such as sound-insulating cotton. Generally, using sound-insulating materials is relatively cheaper and the sound insulation effect can be guaranteed for a long time. Example

[0040] To further reduce the noise during the use of ultra-thin window air conditioners, such as Figures 1 to 8 As shown, a radio receiver 14 is installed inside the housing 1. The radio receiver 14 is used to collect noise signals generated during the operation of the ultra-thin window air conditioner. Multiple active noise cancellation mechanisms 16 are installed inside the housing 1. The active noise cancellation mechanisms 16 perform active noise cancellation operations based on the noise signals collected by the radio receiver 14.

[0041] Specifically, the housing 1 has a built-in noise analysis unit and a control execution unit, which are electrically connected to the radio receiver 14. The noise analysis unit is used to receive the noise signal transmitted by the radio receiver 14, and to extract and analyze the noise signal to obtain the noise analysis result.

[0042] The control execution unit is electrically connected to the noise analysis unit and the active noise reduction mechanism 16 respectively. The control execution unit is used to receive the noise analysis results transmitted by the noise analysis unit, generate control commands based on the noise analysis results, and send control commands to the active noise reduction mechanism 16 to start the active noise reduction mechanism 16.

[0043] The radio receiver 14 includes multiple microphones 15, which are located in the upper and lower cavities, respectively. The active noise cancellation mechanism 16 includes multiple loudspeakers 17, which are also installed in the upper and lower cavities. The two sets of radio receivers 14 and active noise cancellation mechanism 16 can operate independently, processing noise sources in different locations to ensure reasonable noise reduction and avoid increasing noise levels.
