[0055] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0056] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0057] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0058] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0059] In existing fresh air conditioning systems, the fresh air mode is limited, and the application range of fresh air conditioning systems is narrow. For example, children and the elderly are more sensitive to indoor air temperature, and they will feel obvious discomfort when the indoor air temperature changes significantly. Young and middle-aged people are not sensitive to indoor air temperature, and they can adapt to the indoor air temperature in time when the indoor air temperature changes significantly. The fresh air mode control precision is low, which cannot meet the fresh air needs of different users.

[0060] This invention creatively provides a control method for a fresh air conditioning system. The fresh air conditioning system includes a fresh air module, which forms a first fresh air flow path, a second fresh air flow path, an exhaust air flow path, and a return air flow path. When outdoor fresh air flows through the first fresh air flow path, it can exchange heat with indoor air flowing through the exhaust air flow path to achieve a conventional fresh air mode. When outdoor fresh air flows through the second fresh air flow path, it can mix with indoor air flowing through the return air flow path to achieve a general care fresh air mode. The control method includes: determining information about users in the space where the fresh air conditioning system is located, including at least one of age, body parameters, and health status; determining a target fresh air mode based on the user information, including a conventional fresh air mode and a general care fresh air mode; and controlling the fresh air conditioning system to operate in the target fresh air mode.

[0061] This allows the fresh air mode to be matched with the user's information, improving the control accuracy of the fresh air mode and expanding the application range of fresh air air conditioners to meet the fresh air needs of different users; it also solves the problem of user discomfort caused by the mismatch between the fresh air mode and the user's information.

[0062] <Control Methods>

[0063] like Figure 1As shown, this embodiment provides a control method for a fresh air conditioning system. The fresh air conditioning system includes a fresh air module 5, which has a fresh air mode. Depending on the heat exchange method between the introduced outdoor fresh air and indoor air, the fresh air mode includes a conventional fresh air mode, a general care fresh air mode, and a special care fresh air mode. The fresh air module 5 forms a first fresh air flow path, a second fresh air flow path, an exhaust air flow path, and a return air flow path. The first fresh air flow path is not connected to the exhaust air flow path, while the second fresh air flow path is connected to the return air flow path. When the outdoor fresh air flows through the first fresh air flow path, it can exchange heat with the indoor air flowing through the exhaust air flow path, realizing the conventional fresh air mode. This fully utilizes the energy of the exhaust air, bringing the temperature of the introduced outdoor fresh air closer to the temperature of the indoor air. When the outdoor fresh air flows through the second fresh air flow path, it can mix with the indoor air flowing through the return air flow path, realizing the general care fresh air mode. Through mixing, the compatibility between the introduced outdoor fresh air and indoor air is improved, reducing the impact of the introduced outdoor air on the indoor air. The control method includes:

[0064] S1. Determine the information of users in the space where the fresh air air conditioner is located. The user information includes at least one of age, physical parameters, and health status.

[0065] S2. Determine the target fresh air mode based on the user's information. The target fresh air mode includes the regular fresh air mode and the general care fresh air mode.

[0066] S3, control the target fresh air mode of the fresh air conditioner.

[0067] Considering that people of different ages have different sensitivities to temperature, this embodiment proposes that S2 includes:

[0068] S21. Determine whether the user is a child or an elderly person based on their age; specifically, a child is under eighteen years old, and an elderly person is over sixty years old.

[0069] S22. When the user is a child or elderly person, the target fresh air mode is set to the general care fresh air mode. In this mode, the temperature of the introduced indoor fresh air is close to the temperature of the indoor air to ensure the comfort of the indoor air.

[0070] Since people with different physical conditions have different sensitivities to temperature, this embodiment proposes that S2 includes:

[0071] S23. Determine whether the user is a disabled person or a pregnant woman based on the user's physical parameters;

[0072] S24. When the user is a disabled person or a pregnant woman, the target fresh air mode is determined to be the general care fresh air mode; under this mode, the introduced indoor fresh air has little impact on the indoor air and ensures that the indoor air temperature is suitable.

[0073] In view of the different temperature sensitivities of people in different health states, this embodiment proposes that S2 includes:

[0074] S25. Determine whether the user is a patient based on their health status;

[0075] S26. When the user is a patient, the fresh air mode is set to general care fresh air mode. In this mode, the indoor air is refreshed, and the indoor air temperature changes little, so as not to cause discomfort to the patient.

[0076] In response to the increased temperature sensitivity of children or the elderly when their health is poor, this embodiment proposes that the fresh air conditioner also includes an indoor unit body 6, which is located on one side of the fresh air module 5. The indoor unit body 6 forms a return air duct, and the air outlet of the return air duct is connected to the air outlet of the second fresh air flow path. The outdoor fresh air flowing through the second fresh air flow path can mix with the indoor air flowing through the return air duct to achieve a special care fresh air mode. The temperature of the outdoor fresh air is close to the temperature of the indoor air, making the indoor air temperature more suitable for the user's health condition.

[0077] S2 also includes:

[0078] S27. Determine whether the user is a child or an elderly person based on their age;

[0079] S28. When the user is a child or an elderly person, determine whether the user is a disabled person based on the user's physical parameters; or, determine whether the user is a patient based on the user's health status.

[0080] S29. When the user is a disabled person, a pregnant woman, or a patient, the target fresh air mode is determined to be the special care fresh air mode.

[0081] To address the low temperature sensitivity of young or middle-aged users, this embodiment proposes that S2 further includes:

[0082] S210. Determine whether the user is a young adult or middle-aged based on their age.

[0083] S211. When the user is a young or middle-aged person, determine whether the user is a disabled person or a pregnant woman based on the user's physical parameters.

[0084] S222. When the user is not a disabled person or a pregnant woman, determine whether the user is a patient based on the user's health status.

[0085] S213. When the user is not a patient, the target fresh air mode is set to the regular fresh air mode to improve the operating efficiency of the fresh air air conditioner while ensuring the user's comfort.

[0086] like Figures 2 to 7As shown, to address the issues of complex structures and inappropriate placement of the fresh air and exhaust air flow paths, this embodiment proposes that the fresh air module 5 comprises a base duct 111, a fresh air cavity 314, and an exhaust air cavity 324. The air inlet of the base duct 111 is connected to the outside, and the air outlet of the base duct 111 is connected to the fresh air cavity 314. A heat exchanger 21 is provided inside the base duct 111, forming a fresh air heat exchange channel 211 and an exhaust air heat exchange channel 212. Both ends of the fresh air heat exchange channel 211 are connected to the base duct 111, and the base duct 11 and the fresh air cavity 314 are sequentially connected to form a first fresh air flow path. The exhaust air heat exchange channel 212 and the exhaust air cavity 324 are connected to form an exhaust air flow path. Preferably, the heat exchanger 21 is a total heat exchanger.

[0087] When the target fresh air mode is the regular fresh air mode, S3 includes:

[0088] S31, outdoor fresh air flows into the room through base air duct 111, fresh air heat exchange duct 211 and fresh air cavity 314, and indoor air flows out to the outside through exhaust heat exchange duct 212 and exhaust cavity 324.

[0089] Furthermore, a fresh air connecting pipe 181 is provided at the bottom of the base air duct 111, which connects to the fresh air cavity 314 and forms a second fresh air flow path; a return air pipe 182 is also provided inside the base air duct 111, which forms a return air flow path and connects the indoor space with the fresh air cavity 314; when the target fresh air mode is a general care fresh air mode, S3 includes:

[0090] S32. Outdoor fresh air enters the fresh air cavity 314 through the fresh air connecting pipe 181 and mixes with the indoor air that enters the fresh air cavity 314 through the return air pipe 182, and then is discharged into the room.

[0091] When the target fresh air mode is the special care fresh air mode, S3 includes:

[0092] S33. Outdoor fresh air enters through fresh air connecting pipe 181 and fresh air cavity 314, and then mixes with return air discharged through return air duct and is discharged into the room.

[0093] Specifically, addressing the issue of excessive space occupation caused by the unreasonable placement of components in the fresh air module 5, this embodiment proposes that the fresh air module 5 includes a base 1, a fresh air component 31, and an exhaust component 32; the base 1 includes a base body 11, which forms a base air duct 111; the fresh air component 31 and the exhaust component 32 are arranged side by side at the bottom of the base body 11, with the fresh air component 31 forming a fresh air cavity 314 and the exhaust component 32 forming an exhaust cavity 324; the structure is compact and the space utilization rate is high;

[0094] Furthermore, the fresh air assembly 31 includes a fresh air volute 311 and a fresh air volute cover 312, which are fastened together to form a fresh air cavity 314. The fresh air cavity 314 includes a fresh air cavity inlet and a fresh air cavity outlet. The fresh air cavity inlet is formed at the top of the fresh air cavity 314 and is connected to the air outlet of the base air duct 111. The fresh air cavity outlet is formed at the bottom of the fresh air cavity 314 and is connected to the indoor environment. This allows outdoor fresh air to smoothly enter the fresh air cavity 314 through the base air duct 111 and the fresh air cavity inlet, and to be smoothly discharged into the indoor environment through the fresh air cavity outlet.

[0095] The exhaust assembly 32 includes an exhaust volute 321 and an exhaust volute cover 322. The exhaust volute 321 and the exhaust volute cover 322 are fastened together to form an exhaust cavity 324. The exhaust cavity 324 includes an exhaust cavity inlet and an exhaust cavity outlet. The exhaust cavity inlet is formed at the top of the exhaust cavity 324 and is connected to the air outlet of the exhaust heat exchange duct 212. The exhaust cavity outlet is formed on the side of the exhaust cavity 324 and is connected to the outside. This allows indoor air to smoothly enter the exhaust cavity 324 through the exhaust heat exchange duct 212 and the exhaust cavity inlet, and smoothly exit to the outside through the exhaust cavity outlet.

[0096] To address the issue of the complex structure of the drive mechanism in the fresh air module 5, this embodiment proposes that the fresh air assembly 31 further includes a fresh air fan blade 313, which is rotatably disposed within the fresh air cavity 314; the exhaust assembly 32 further includes an exhaust fan blade 323, which is rotatably disposed within the exhaust cavity 324; the fresh air volute 311 has a first shaft hole that communicates with the fresh air cavity 314; the exhaust volute 321 has a second shaft hole that communicates with the exhaust cavity 324.

[0097] The fresh air module 5 also includes a drive motor 33, which is disposed between the fresh air volute 311 and the exhaust volute 321. The output shaft of the drive motor 33 includes a first shaft end 331 and a second shaft end 332. The first shaft end 331 passes through the first shaft hole and is driven to connect with the fresh air fan blade 313. The second shaft end 332 passes through the second shaft hole and is driven to connect with the exhaust fan blade 323.

[0098] When the drive motor 33 rotates, the fresh air fan blade 313 and the exhaust fan blade 323 can rotate synchronously.

[0099] Furthermore, the base 1 also includes a base plate 12, which is disposed on one side of the base body 11 and close to the air inlet end of the base air duct 111. A fresh air inlet pipe 131 and an exhaust pipe 132 are provided on the side of the base plate 12 away from the base body 11. The fresh air inlet pipe 131 connects the air inlet end of the base air duct 111 to the outside, and the exhaust pipe 132 connects the outlet of the exhaust cavity 324 to the outside.

[0100] To address the issues of insecure fixing and poor sealing of the filter 22 and heat exchange component 21, this embodiment proposes that the base air duct 111 includes a first mounting position and a second mounting position, which are arranged sequentially along the direction of fresh air flow; a first frame 141 is provided at the first mounting position, and the filter 22 is provided on the first frame 141; the fresh air in the base air duct 111 can flow through the filter 22;

[0101] A second frame 142 is provided at the second installation position, and a heat exchange component 21 is provided on the second frame 142; specifically, both the first frame 141 and the second frame 142 are cuboid structures, and both the filter 22 and the heat exchange component 21 are cuboid structures.

[0102] Furthermore, the filter 22 is sealed to the first frame 141, and the heat exchanger 21 is sealed to the second frame 142; the seal is tight, so that the fresh air in the base air duct 111 flows through the filter 22 and the fresh air heat exchange duct 211 in sequence and enters the fresh air cavity 314, and the air in the exhaust heat exchange duct 212 enters the exhaust cavity 324.

[0103] A first partition 151 is provided between the base body 11 and the fresh air assembly 31. The first partition 151 is close to the base plate 12. The first partition 151, the base plate 12, and the side wall of the base body 11 form a fresh air inlet cavity 161. The fresh air inlet cavity 161 is connected to the inlet end of the fresh air inlet pipe 131 and the base air duct 111. When the fresh air conditioner is running in the normal fresh air mode, the outdoor fresh air flows through the fresh air inlet pipe 131 and the fresh air inlet cavity 161 in sequence and enters the base air duct 111. Alternatively, the fresh air inlet cavity 161 is connected to the fresh air inlet pipe 131 and the fresh air connecting pipe. When the fresh air conditioner is running in the general care fresh air mode or the special care fresh air mode, the outdoor fresh air flows through the fresh air inlet pipe 131 and the fresh air inlet cavity 161 in sequence and enters the fresh air connecting pipe, and then enters the fresh air cavity 314.

[0104] A second partition 152 is also provided between the base body 11 and the fresh air component 31. A fresh air connection port is formed between the second partition 152 and the side wall of the base body 11. The fresh air connection port connects the air outlet of the base air duct 111 and the inlet of the fresh air cavity 314. An exhaust connection cavity 162 is formed between the second partition 152, the first frame 141, the second frame 142 and the exhaust volute 321. The exhaust connection cavity 162 connects the exhaust heat exchange duct 212 and the inlet of the exhaust cavity 324. The air in the exhaust heat exchange duct 212 enters the exhaust cavity 324 through the exhaust connection cavity 162.

[0105] An electrical box mounting position is also formed on the bottom side of the base plate 12 near the base body 11. The electrical box 23 is set at the electrical box mounting position and is connected to the base plate 12 by threads. A fresh air control board is set inside the electrical box 23. The fresh air control board is electrically connected to the drive motor 33 to control the operation of the drive motor 33.
