[0046] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] like Figures 1 to 4 As shown, one embodiment of the present invention provides a fresh air device, which includes a device body 1, fan blades 2, and a heat exchange assembly 3. The device body 1 has an air cavity 11 and an air inlet 12 and an air outlet 13 connected to the air cavity 11. The fan blades 2 are arranged in the air cavity 11. The heat exchange assembly 3 includes a heating part 31 for heating the air and a cooling part 32 for cooling the air; wherein the heat exchange assembly 3 is movably arranged in the air cavity 11 to move to a heating position with the heating part 31 facing the air inlet direction or a cooling position with the cooling part 32 facing the air inlet direction.

[0048] The fresh air device provided by one embodiment of the present invention is provided with a movable heat exchange component 3, so that the fresh air device can flexibly switch between the heating position and the cooling position, so that the fresh air entering the room can be pre-heated or cooled, so that it can better match the indoor air temperature and improve the comfort of the fresh air entering. When the temperature of the fresh air is lower than the required indoor air temperature, the heating part 31 of the fresh air device can pre-heat the incoming air; when the temperature of the fresh air is higher than the required indoor air temperature, the cooling part 32 of the fresh air device can pre-cool the air. This reduces the sudden change in indoor temperature caused by the introduction of untreated outdoor air, helps to maintain a stable and comfortable indoor environment, and thus improves the user experience and satisfaction. In addition, the heat exchange component 3 is integrated into the air cavity 11 of the device body 1, and its movable characteristics are used to achieve function switching. This design method helps to make the structure of the fresh air device compact, facilitates installation and use in various air-conditioning systems, and also reduces the space occupied by the equipment and improves installation flexibility. To enhance airflow comfort, conventional fresh air devices typically require different duct designs based on the installation of cooling or heating equipment. However, this solution achieves different heat exchange effects for the fresh air simply by rotating the heat exchange assembly 3, eliminating the need for wind direction control in different ducts. This results in a simpler and more efficient structure. Therefore, the fresh air device provided by this embodiment can address the technical issue of low airflow comfort in existing fresh air devices.

[0049] Specifically, the heating unit 31 can be a heating structure that can be used to heat the air, such as an electric heating element, an infrared heater, or a warm air pipe. The cooling unit 32 can be a cooling structure that can be used to cool the air, such as a semiconductor refrigerator, an absorption refrigerator, or a thermoelectric cooling plate. The fan blades 2 are centrifugal fan blades.

[0050] In one embodiment, the heat exchange assembly 3 is positioned between the fan blades 2 and the air inlet 12. When the heat exchange assembly 3 is in the heating position, the heating portion 31 is positioned opposite the air inlet 12; when the heat exchange assembly 3 is in the cooling position, the cooling portion 32 is positioned opposite the air inlet 12. Thus, when the heat exchange assembly 3 is in the heating position, the heating portion 31 directly contacts the fresh air entering from the air inlet 12, immediately heating it and ensuring that the air is preheated before entering the fan blades 2. This effectively raises the subsequent indoor air temperature and enhances the heating effect. When the heat exchange assembly 3 is in the cooling position, the cooling portion 32 first contacts the fresh air entering from the air inlet 12 and rapidly cools it, ensuring that the air is precooled before entering the fan blades 2. This lowers the air temperature, reduces the indoor air conditioning pressure, optimizes the energy efficiency of the entire system, and improves user comfort. If fresh air is directly introduced without preheating or precooling, especially during rapid temperature fluctuations (such as the sudden influx of cold air during winter), it may cause increased thermal stress on the fan blade 2 material, reducing its long-term service life and reliability. Preheating or precooling the air can reduce the thermal shock and protect the fan blades 2 and related mechanical components.

[0051] Specifically, the heat exchange component 3 is arranged at the air inlet 12. In this way, the heat exchange component 3 is placed at the air inlet 12, which can immediately control the temperature of the incoming fresh air (preheating or precooling), ensuring that the air temperature before entering the fan blades 2 is close to the target temperature, thereby improving the working efficiency of the entire system.

[0052] Specifically, the maximum distance between the heat exchange assembly 3 and the air inlet 12 is greater than 0 mm and less than or equal to 30 mm. This structural arrangement maintains a reasonable distance between the heat exchange assembly 3 and the air inlet 12, maximizing heat exchange efficiency and ensuring that the air is adequately heated or cooled within the shortest possible path, thereby avoiding excessive energy loss.

[0053] In one embodiment, the heat exchange component 3 is arranged between the fan blade 2 and the air outlet 13; when the heat exchange component 3 is in the heating position, the heating part 31 is arranged opposite to the air outlet surface of the fan blade 2; when the heat exchange component 3 is in the cooling position, the cooling part 32 is arranged opposite to the air outlet surface of the fan blade 2. In this way, it can better ensure that the fresh air to be heated or cooled flows out directly from the air outlet 13, thereby ensuring that the fresh air flowing out of the air outlet 13 meets the indoor temperature requirements without losing heat or cooling during the flow in the air cavity 11. In the heating position, the heating part 31 is arranged opposite to the air outlet surface of the fan blade 2, which means that after being accelerated by the fan blade 2, the air will directly contact the heated heating part 31, further increasing the air temperature, ensuring that the output fresh air fully meets the requirements of indoor temperature regulation, and optimizing the heating effect and efficiency. In the cooling position, the cooling part 32 is arranged opposite to the air outlet surface of the fan blade 2. After being accelerated by the fan blade 2, the air comes into contact with the cooled cooling part 32, and the air temperature is quickly reduced through the efficient cooling capacity, ensuring that the output fresh air meets the requirements of indoor temperature regulation, while ensuring stable control of the indoor temperature.

[0054] Specifically, the minimum distance between the heat exchange assembly 3 and the air outlet 13 is greater than 30 mm. This structural arrangement prevents the heat exchange process from adversely affecting the outgoing airflow, such as temperature rebound or airflow turbulence, thereby ensuring the stability and precise control of the outlet air temperature.

[0055] Specifically, the projected area of the heat exchange assembly 3 on the surface of the air outlet 13 is larger than the flow area of the air outlet 13. This structural arrangement increases the effective contact area between the air and the heat exchange assembly 3, further improving heat exchange efficiency and preventing some airflow from exiting the air outlet 13 without fully exchanging heat with the heat exchange assembly 3. Especially during high-air-volume operation, the larger area of the heat exchange assembly 3 can handle a greater amount of air flow, ensuring that temperature control effectiveness is not compromised even at high air volumes, thereby improving the fresh air device's adaptability to diverse operating conditions.

[0056] In one embodiment, there are at least two heat exchange assemblies 3, one of which is disposed between the fan blades 2 and the air inlet 12, and the other between the fan blades 2 and the air outlet 13. This structural arrangement ensures that the fresh air flowing out of the air outlet 13 meets the indoor temperature requirement through the synergistic effect of the two heat exchange assemblies 3, further ensuring comfortable airflow.

[0057] In one embodiment, the heat exchange assembly 3 is rotatably arranged; the heat exchange assembly 3 also includes a heat exchange body 30, which has a first mounting surface and a second mounting surface, with the heating unit 31 being arranged on the first mounting surface and the cooling unit 32 being arranged on the second mounting surface; wherein: the first mounting surface and the second mounting surface are arranged relative to each other, and the extension direction of the first mounting surface is parallel to the extension direction of the second mounting surface. With such a structural arrangement, the rotatable design of the heat exchange assembly 3 enables the heating unit 31 and the cooling unit 32 to switch positions with each other, quickly responding to the cooling or heating needs of the indoor air conditioning system, and improving the flexibility and responsiveness of the system. Because the first mounting surface and the second mounting surface are parallel to each other, mode switching can be completed through a simple rotation, which not only reduces the complexity of the equipment, but also simplifies the design of the control system, thereby reducing manufacturing costs and maintenance difficulties.

[0058] Specifically, the heat exchange assembly 3 is a plate-like structure, with the heating unit 31 and cooling unit 32 disposed on opposite sides of the plate. This effectively utilizes limited space, allowing the heat exchange assembly 3 to achieve dual temperature regulation while occupying a relatively small volume. Furthermore, the plate-like design increases the contact area between the heating unit 31 and cooling unit 32 and the air.

[0059] Specifically, the fresh air device also includes a drive motor, the shaft of which is rotatably connected to the heat exchange assembly 3 to drive the heat exchange assembly 3 to rotate. Specifically, the drive motor is a stepper motor, so that the number of pulses of the stepper motor can be controlled to achieve smooth rotation of the heat exchange assembly 3, ensuring that the heating unit 31 or the cooling unit 32 is accurately aligned with the air duct.

[0060] In one embodiment, the heat exchange assembly 3 is rotatably arranged; the heat exchange assembly 3 also includes a heat exchange body 30, the heat exchange body 30 has a first mounting surface and a second mounting surface, the heating part 31 is arranged on the first mounting surface, and the cooling part 32 is arranged on the second mounting surface; wherein: the extension direction of the first mounting surface and the extension direction of the second mounting surface are arranged at a first preset angle, and the first preset angle is greater than 0° and less than 180°. With such a structural setting, the non-parallel angle setting allows the rotation angle to be fine-tuned according to specific environmental conditions, thereby more effectively utilizing or reducing the impact of airflow on the heat exchange surface, and improving the applicability and efficiency of the fresh air device in different scenarios. Compared with a completely parallel setting, a mounting surface with a certain angle can change the air flow path more quickly, reduce the transition time and energy consumption from the cooling position to the heating position (or vice versa), and improve the overall performance and energy saving effect of the system.

[0061] In one embodiment, the fresh air device further includes an air deflector disposed between the air inlet 12 and the heat exchange assembly 3, and the air deflector is rotatably disposed. With this structural arrangement, the rotatable design of the air deflector can precisely direct the incoming airflow as needed, ensuring that air flows directly and efficiently to the heat exchange assembly 3, reducing fluid resistance, optimizing airflow distribution, and improving heat exchange efficiency.

[0062] Specifically, the heat exchange assembly 3 further includes a first air deflector and a second air deflector. One end of the first air deflector is connected to the first mounting surface, the other end of the first air deflector protrudes from the heating portion 31, and the first air deflector extends at a second preset angle relative to the first mounting surface. One end of the second air deflector is connected to the second mounting surface, the other end of the second air deflector protrudes from the cooling portion 32, and the second air deflector extends at a third preset angle relative to the second mounting surface. The second preset angle and the third preset angle are both greater than 0° and less than or equal to 90°. With this structural arrangement, the arrangement of the first and second air deflectors, particularly their relative positions relative to the heating portion 31 and the cooling portion 32 of the heat exchange assembly 3, helps to evenly distribute air across the entire heat exchange surface, thereby improving the uniformity and efficiency of heat exchange. The second and third preset angles can also be adjusted according to the specific application scenario and indoor temperature requirements, thereby adjusting the heat exchange effect between the heat exchange assembly 3 and the fresh air.

[0063] Specifically, there are multiple first air guide plates and multiple second air guide plates; the multiple first air guide plates are spaced apart along the extension direction of the first mounting surface, with at least a portion of the heating portion 31 located between two adjacent first air guide plates, thereby forming a heating cavity between the two adjacent first air guide plates; the multiple second air guide plates are spaced apart along the extension direction of the second mounting surface, with at least a portion of the cooling portion 32 located between two adjacent second air guide plates, thereby forming a cooling cavity between the two adjacent second air guide plates. With this structural arrangement, by forming a heating cavity between two adjacent first air guide plates and a cooling cavity between two adjacent second air guide plates, localized and centralized air processing is achieved, and the air in each cavity can be adequately temperature-regulated, thereby improving the overall heat exchange efficiency.

[0064] like Figure 4As shown, the fresh air device also includes a volute cover 14, a motor 15, a motor bracket 16, a volute 17, a mounting box 18, a filter structure 6, an air duct joint 19, a fresh air duct 110 and a rainproof joint 111. The volute cover 14 and the volute 17 together form a blade cavity for accommodating the fan blades 2, which effectively improves the efficiency of air circulation. The motor 15 is fixed on the motor bracket 16, and the motor 15 is driven and connected to the fan blades 2. The mounting box 18 is used to enclose the air cavity 11, and the filter structure 6 is arranged between the volute 17 and the mounting box 18. The heat exchange component 3 is arranged between the mounting box 18 and the air inlet 12, and performs temperature adjustment in the early stage of the fresh air entering, ensuring rapid adjustment of the fresh air temperature, improving the heat exchange efficiency, and reducing the difference between the fresh air temperature and the indoor ambient temperature. The fresh air duct 110 is connected to the air inlet 12 through the air duct joint 19. A rainproof joint 111 is provided at one end of the fresh air duct 110 away from the air duct joint 19, which effectively prevents rainwater from entering the room through the fresh air duct 110, improves the sealing and moisture-proof ability of the system, extends the service life of the equipment, and also avoids damage to electrical components such as the motor 15 by rainwater.

[0065] Specifically, the filter structure 6 includes a healthy filter. Specifically, the healthy filter can be a HEPA (High Efficiency Particulate Air) filter, an activated carbon filter layer, a photocatalyst filter material, an electrostatic dust filter, or other filter components capable of filtering fine particulate matter and harmful gases in the air. This effectively intercepts pollutants in the air, improves the cleanliness of fresh air, and protects the indoor environment from external pollution. At the same time, the layout design of the filter structure 6 ensures smoother air circulation, avoiding the problem of reduced air volume due to filter blockage.

[0066] like Figure 5 As shown, an embodiment of the present invention provides an air conditioner, which includes: an air conditioner main body 5 and the above-mentioned fresh air device, and the fresh air device is arranged on the air conditioner main body 5.

[0067] An air conditioner provided in one embodiment of the present invention utilizes a movable heat exchange assembly 3, allowing the fresh air device to flexibly switch between heating and cooling positions. This allows the incoming fresh air to be pre-heated or pre-cooled, better matching the indoor air temperature and improving the comfort of the incoming fresh air. When the fresh air temperature is lower than the desired indoor air temperature, the heating unit 31 of the fresh air device preheats the incoming air; when the fresh air temperature is higher than the desired indoor air temperature, the cooling unit 32 of the fresh air device pre-cools the air. This reduces sudden changes in indoor temperature caused by the introduction of untreated outdoor air, helps maintain a stable and comfortable indoor environment, and thus enhances user experience and satisfaction. Furthermore, the heat exchange assembly 3 is integrated into the air cavity 11 of the device body 1, utilizing its movable nature to achieve functional switching. This design contributes to the compactness of the fresh air device, facilitating installation and use in various air conditioning systems. It also reduces the space occupied by the device and enhances installation flexibility. Therefore, the air conditioner provided in this embodiment can address the technical problem of low air comfort in existing fresh air devices.

[0068] Specifically, to ensure fresh air is delivered, the air conditioner body 5 is provided with an air outlet 51 on its surface, which communicates with the air outlet 13. The air outlet 51 is located at the bottom of the air conditioner body 5. Compared to traditional top or side air delivery, bottom air delivery provides better air diffusion, quickly covering the entire indoor space, improving air quality uniformity, and providing users with a more comfortable and healthy living environment.

[0069] Specifically, the air conditioner further includes a detection component and a control component. The detection component is used to detect the operating mode of the air conditioner. The heat exchange assembly 3 of the fresh air unit and the detection component are both connected to the control component. The control component is used to control the movement of the heat exchange assembly 3 to its cooling position or heating position based on the detection result of the detection component, thereby activating the heating unit 31 or cooling unit 32 of the corresponding heat exchange assembly 3. With this structural arrangement, the detection component monitors in real time whether the air conditioner is currently in cooling or heating mode and promptly provides feedback to the control component. Based on the feedback from the detection component, the control component precisely controls the movement of the heat exchange assembly 3 to the cooling or heating position and activates the corresponding heating unit 31 or cooling unit 32. This seamless integration mechanism ensures synchronization of the operating modes of the fresh air unit and the main air conditioner system, avoiding unnecessary energy waste and improving the overall system's operating efficiency and energy utilization. The combination of automated mode switching and precise temperature control significantly improves indoor comfort. Whether in cold winter or hot summer, users can enjoy fresh air at just the right temperature, enhancing their satisfaction with the air conditioning system.

[0070] It should be noted that the operating modes of the air conditioner include cooling mode and heating mode.

[0071] Specifically, the fresh air device further includes a temperature detector, the detection end of which is disposed at the air outlet 13 to detect the outlet air temperature at the air outlet 13; a control unit connected to the temperature detector; wherein: the control unit includes a receiving module and a transmitting module, the receiving module being signal-connected to the temperature detector and configured to receive the detection signal from the temperature detector; the cooling unit 32 and the heating unit 31 are both signal-connected to the transmitting module, the transmitting module being configured to send a control signal to the cooling unit 32 or the heating unit 31 to adjust the operating power of the cooling unit 32 or the heating unit 31 according to the detection result of the temperature detector. With such a structural arrangement, the receiving module of the control unit receives the signal from the temperature detector, and the transmitting module sends a control instruction to the cooling unit 32 or the heating unit 31. Based on the difference between the detected outlet air temperature and the set value, the operating power of the component is intelligently adjusted, thereby achieving precise control of the outlet air temperature and providing a more comfortable indoor environment.

[0072] Specifically, the fresh air device also includes a temperature detection component, the detection end of the temperature detection component is set at the air outlet 13 to detect the outlet air temperature at the air outlet 13; the control component is connected to the temperature detection component; the fresh air device also includes a first damper 41 set at the air outlet 13, and the first damper 41 is set to open and close; the first damper 41 is connected to the control component, and the control component is used to control the opening of the first damper 41 according to the detection result of the temperature detection component. With such a structural setting, the setting of the first damper 41 enables the control component to accurately adjust the air volume of the air outlet according to the feedback information of the temperature detection component. When the outlet air temperature is higher or lower than the target temperature, it means that the outlet air temperature at this time is significantly different from the expected temperature. At this time, the amount of fresh air entering the room can be reduced by adjusting the first damper 41, so that the fresh air stays in the air cavity 11 for heat exchange, effectively assisting temperature control and improving the flexibility and efficiency of temperature regulation. When the temperature changes rapidly or the air-conditioning system is under high load, intelligent control of the opening of the first damper 41 can prevent excessive cold or hot air from suddenly rushing into the room, causing large fluctuations in the indoor temperature, thereby ensuring the stability and comfort of the indoor temperature.

[0073] Specifically, the fresh air device further includes a temperature detector, the detection end of which is disposed at the air outlet 13 to detect the outlet air temperature at the air outlet 13; a control unit is connected to the temperature detector; the fresh air device further includes a second damper 42 disposed at the air inlet 12, the second damper 42 being openable and closable; and the second damper 42 is connected to the control unit, which is configured to control the opening of the second damper 42 based on the detection result of the temperature detector. With this structural arrangement, the dynamic control of the second damper 42 enables the air conditioning system to flexibly adjust the amount of air entering the fresh air device based on the indoor temperature requirement and external air conditions, thereby optimizing the heat exchange process, ensuring that the fresh air entering the room quickly reaches the ideal temperature, and improving the user experience. When the outlet air temperature is higher or lower than the target temperature, indicating that the outlet air temperature at this time is significantly different from the expected temperature, the second damper 42 can be adjusted to reduce the amount of fresh air introduced, thereby preventing excessive fresh air from entering and not being able to fully exchange heat with the heat exchange component 3, thereby affecting the indoor temperature comfort.

[0074] One embodiment of the present invention provides a control method applicable to the above-mentioned air conditioner, the control method comprising: obtaining the working mode of the air conditioner; when the air conditioner is in heating mode, moving the heat exchange component 3 of the air conditioner to the heating position and starting the heating part 31 of the heat exchange component 3; when the air conditioner is in cooling mode, moving the heat exchange component 3 to the cooling position and starting the cooling part 32 of the heat exchange component 3.

[0075] The control method provided by one embodiment of the present invention can dynamically respond to the working mode of the air conditioner. Whether it is heating mode or cooling mode, it can quickly adjust the heat exchange component 3 to the correct working position and start the corresponding heating part 31 or cooling part 32, thereby ensuring the precise matching of the fresh air and the working mode of the air conditioning system, and improving the response speed and intelligence level of the system. Through the control of the position of the heat exchange component 3 and the operation of the heating part 31 or cooling part 32 by the control component, the precise regulation of the fresh air temperature is achieved. In heating mode, the fresh air will be heated to a temperature close to or equal to the indoor target temperature, and in cooling mode, the fresh air will be cooled to the indoor target temperature. This significantly improves the temperature control accuracy of the air conditioning system and improves the comfort of the indoor environment. Regardless of how the outdoor weather changes, the user can enjoy fresh air at a suitable temperature, which enhances the user's satisfaction and experience with the air conditioning system. Therefore, the control method provided by this embodiment can solve the technical problem of low air outlet comfort of the fresh air device in the prior art.

[0076] Specifically, after the air conditioner's heat exchange assembly 3 is moved to the heating position and the heating unit 31 of the heat exchange assembly 3 begins operating, the control method further includes: obtaining the temperature at the air outlet 13 of the air conditioner's fresh air device and the temperature of the indoor environment in which the air conditioner's indoor unit is located to obtain the outlet air temperature and the ambient temperature, respectively; when the difference between the outlet air temperature and the ambient temperature is greater than a first preset temperature difference; if the outlet air temperature is lower than the ambient temperature, increasing the operating power of the heating unit 31; if the outlet air temperature is higher than the ambient temperature, reducing the operating power of the heating unit 31; and when the difference between the outlet air temperature and the ambient temperature is less than or equal to the first preset temperature difference, maintaining the current operating power of the heating unit 31 unchanged. With this configuration, after the heat exchange assembly 3 is moved to the heating position and the heating unit 31 begins operating, the control unit can continuously obtain the outlet air temperature at the air outlet 13 and the ambient temperature of the indoor environment, and dynamically monitor the temperature difference by calculating the difference between the two. This monitoring mechanism ensures that the system can perceive the difference between the fresh air temperature and the indoor ambient temperature in real time, providing a basis for further power adjustment. When the difference between the outlet air temperature and the ambient temperature exceeds a first preset temperature difference, the control unit will take appropriate measures to adjust the operating power of the heating unit 31. If the outlet air temperature is lower than the ambient temperature, the system will increase the operating power of the heating unit 31 to accelerate the heating process of the fresh air. Otherwise, it will reduce the operating power, thereby effectively controlling the final temperature of the fresh air to bring it close to the indoor target temperature and improving the accuracy of temperature regulation. When the difference between the outlet air temperature and the ambient temperature remains within the first preset temperature difference, the control unit will maintain the current operating power of the heating unit 31 unchanged. This stable power strategy helps maintain the temperature difference between the fresh air and the indoor environment within a reasonable range, avoids unnecessary energy fluctuations and losses, and improves the efficiency of energy use.

[0077] Specifically, after the heat exchange assembly 3 is moved to the cooling position and the refrigeration unit 32 of the heat exchange assembly 3 begins operating, the control method further includes: obtaining the temperature at the outlet 13 of the air conditioner's fresh air device and the temperature of the indoor environment in which the air conditioner's indoor unit is located to obtain the outlet air temperature and the ambient temperature, respectively; when the difference between the outlet air temperature and the ambient temperature is greater than a second preset temperature difference; if the outlet air temperature is lower than the ambient temperature, reducing the operating power of the refrigeration unit 32; if the outlet air temperature is higher than the ambient temperature, increasing the operating power of the refrigeration unit 32; and when the difference between the outlet air temperature and the ambient temperature is less than or equal to the preset temperature difference, maintaining the current operating power of the refrigeration unit 32 unchanged. With this configuration, after the heat exchange assembly 3 is switched to the cooling position and the refrigeration unit 32 begins operating, the control unit also continuously monitors the difference between the outlet air temperature at the outlet 13 and the ambient temperature of the indoor environment. Based on a comparison of this difference with the second preset temperature difference, the operating power of the refrigeration unit 32 is automatically adjusted to ensure that the fresh air temperature is neither too cold nor too hot, meeting the indoor cooling requirements. By reducing the operating power of the refrigeration unit 32 when the outlet air temperature is lower than the ambient temperature, overcooling is avoided and energy is saved. Conversely, when the outlet air temperature is higher than the ambient temperature, increasing the operating power accelerates the cooling process, ensuring that the indoor temperature quickly reaches a comfortable level while avoiding energy waste caused by excessive temperature differences. When the difference between the outlet air temperature and the ambient temperature is less than or equal to a second preset temperature difference, the controller maintains the current operating power of the refrigeration unit 32. This constant power strategy helps stabilize the indoor temperature, prevents frequent temperature fluctuations, and provides a more comfortable and energy-efficient cooling experience.

[0078] In one embodiment, a first damper 41 that can be opened and closed is provided at the air outlet 13 of the fresh air device of the air conditioner, and a second damper 42 that can be opened and closed is provided at the air inlet 12 of the fresh air device; the control method also includes: obtaining the temperature at the air outlet 13 of the fresh air device of the air conditioner and the temperature of the indoor environment in which the indoor unit of the air conditioner is located to obtain the outlet air temperature and the ambient temperature respectively; after obtaining the outlet air temperature and the ambient temperature, the control method also includes: when the difference between the outlet air temperature and the ambient temperature is greater than a third preset temperature difference, reducing the opening of the first damper 41; when the difference between the outlet air temperature and the ambient temperature is less than or equal to the third preset temperature difference, keeping the opening of the first damper 41 unchanged. With this arrangement, by providing a first damper 41 and a second damper 42 that can be opened and closed, the flow rate of fresh air flowing in and out can be precisely controlled. When the difference between the outlet air temperature and the ambient temperature exceeds a third preset temperature difference value, the control component will reduce the opening of the first damper 41, reducing the flow rate of fresh air. Conversely, the opening of the first damper 41 will remain unchanged. This strategy effectively reduces the impact of the temperature difference between the fresh air and the indoor temperature on the indoor temperature when there is a certain temperature difference between the fresh air and the indoor temperature, thereby improving the accuracy of temperature control. By controlling the opening of the first damper 41, the system can limit the entry of excessive temperature-sensitive fresh air under conditions of large temperature differences, thereby avoiding large fluctuations in indoor temperature. When the temperature difference is small, the damper opening is kept unchanged to maintain normal indoor air circulation and achieve balanced temperature regulation.

[0079] In one embodiment, a fresh air device of an air conditioner is provided with an openable and closable first damper 41 at the air outlet 13, and an openable and closable second damper 42 at the air inlet 12 of the fresh air device. The control method further comprises: obtaining the temperature at the air outlet 13 of the fresh air device and the temperature of the indoor environment in which the indoor unit of the air conditioner is located to obtain an outlet air temperature and an ambient temperature, respectively. After obtaining the outlet air temperature and the ambient temperature, the control method further comprises: when the difference between the outlet air temperature and the ambient temperature is greater than a fourth preset temperature difference, reducing the opening of the second damper 42; and when the difference between the outlet air temperature and the ambient temperature is less than or equal to the fourth preset temperature difference, maintaining the opening of the second damper 42 unchanged. With this arrangement, when the difference between the outlet air temperature and the ambient temperature is greater than the fourth preset temperature difference, the control component reduces the opening of the second damper 42, thereby reducing the amount of outdoor fresh air introduced, effectively preventing fresh air with a large temperature difference from directly entering the room, causing an uncomfortable indoor temperature or wasting energy. By reducing the opening of the second damper 42, the air conditioning system can better control the indoor temperature, avoid indoor temperature fluctuations caused by the entry of a large amount of fresh air with significant temperature differences, and ensure that the user's comfort experience is not affected.

[0080] One embodiment of the present invention provides a control device, which is applicable to the above-mentioned control method. The control device includes an acquisition unit and a control unit. The acquisition unit is used to obtain the working mode of the air conditioner; the control unit is used to move the heat exchange component 3 of the air conditioner to the heating position and start the heating part 31 of the heat exchange component 3 when the air conditioner is in the heating mode; when the air conditioner is in the cooling mode, the control unit is used to move the heat exchange component 3 to the cooling position and start the cooling part 32 of the heat exchange component 3.

[0081] The control device provided by one embodiment of the present invention can dynamically respond to the working mode of the air conditioner. Whether it is heating mode or cooling mode, it can quickly adjust the heat exchange component 3 to the correct working position and start the corresponding heating part 31 or cooling part 32, thereby ensuring the precise matching of the fresh air and the working mode of the air conditioning system, and improving the response speed and intelligence level of the system. Through the control of the position of the heat exchange component 3 and the operation of the heating part 31 or cooling part 32 by the control component, the precise regulation of the fresh air temperature is achieved. In heating mode, the fresh air will be heated to a temperature close to or equal to the indoor target temperature. In cooling mode, the fresh air will be cooled to the indoor target temperature. This significantly improves the temperature control accuracy of the air conditioning system and improves the comfort of the indoor environment. Regardless of how the outdoor weather changes, the user can enjoy fresh air at a suitable temperature, which enhances the user's satisfaction and experience with the air conditioning system. Therefore, the control device provided by this embodiment can solve the technical problem of low air outlet comfort of the fresh air device in the prior art.

[0082] An embodiment of the present invention provides a non-volatile storage medium, wherein the non-volatile storage medium includes a stored program, wherein when the program is running, the device where the non-volatile storage medium is located is controlled to execute the above-mentioned control method.

[0083] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: the heat exchange component of the fresh air device can switch between the heating part and the cooling part, and automatically adjust the temperature of the fresh air according to the working mode of the air conditioner (heating or cooling), ensuring the minimum temperature difference between the fresh air and the indoor set temperature, reducing the impact on the indoor temperature field, and improving the comfort of the living or working environment. The control component is connected to the heat exchange component, the detection component and the damper component, and can fine-tune the power of the heat exchange component in real time according to the temperature difference to avoid excessive energy consumption. At the same time, by adjusting the opening of the first damper and the second damper, the fresh air flow rate is optimized to further improve energy utilization efficiency. Compared with the traditional dual-duct fresh air system, this solution simplifies the fresh air channel through the dual-mode design of the heat exchange component (heating position and cooling position), reduces the system complexity and manufacturing cost, and at the same time ensures or even exceeds the performance of the traditional system, reflecting the economic benefits of technological innovation.
