[0002] A fresh air system is an effective air purification device that circulates indoor air. On the one hand, it expels stale indoor air to the outside, and on the other hand, it introduces fresh outdoor air into the room after sterilization, disinfection, and filtration, ensuring that the room is always filled with fresh and clean air.

The fresh air duct and the return air duct exchange heat through a capillary heat pipe heat exchanger. One end of the return air duct is a return air inlet located indoors, and the other end is an exhaust air inlet located outdoors. One end of the fresh air duct is a supply air inlet located indoors, and the other end is a fresh air inlet located outdoors. Variable frequency fans are installed in the fresh air inlet and the exhaust air inlet, respectively. A return air bypass duct connects the return air ducts located on both sides of the capillary heat pipe heat exchanger. A converging bypass duct connects the return air duct located inside the return air inlet and the fresh air duct located inside the fresh air inlet. Electric regulating dampers are installed in the return air bypass duct and the converging bypass duct, respectively.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The related electric regulating damper can only be fully open or fully closed, and cannot accurately adjust the supply air temperature.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a damper mechanism, a fresh air unit, a method and apparatus for regulating air supply, and a computer-readable storage medium to more accurately regulate the air supply temperature.

[0009] In some embodiments, the damper mechanism includes: a support frame with an air inlet; a drive mechanism disposed on the support frame; and a damper disposed at the air inlet and connected to the drive mechanism in a transmission manner. When the return air inlet and the bypass air inlet are arranged side-by-side on the same side of the damper mechanism, the damper moves within the air inlet under the drive of the drive mechanism, thereby changing the proportion of return air entering the return air inlet and the bypass air inlet from both sides of the damper.

[0010] In some embodiments, the fresh air unit includes: a housing with an internal structure forming a return air vent and a bypass air vent; and the aforementioned damper mechanism; wherein the return air vent and the bypass air vent are both located on the same side of the damper mechanism and correspond to the damper mechanism.

[0011] In some embodiments, the method for adjusting the air supply is applied to the aforementioned fresh air unit, and the method includes: calculating a first temperature difference between the return air temperature and the fresh air temperature; determining the opening degree of the bypass vent based on the first temperature difference; and controlling the movement of the damper based on the opening degree of the bypass vent.

[0012] In some embodiments, the means for regulating air supply includes a processor and a memory storing program instructions, the processor being configured to execute the aforementioned method for regulating air supply when the program instructions are executed.

[0013] In some embodiments, the computer-readable storage medium stores program instructions that, when executed, perform the aforementioned method for regulating air supply.

[0014] The damper mechanism, fresh air unit, method and apparatus for regulating air supply, and computer-readable storage medium provided in the embodiments of this disclosure can achieve the following technical effects:

[0015] The support frame is equipped with an air inlet, and an air damper is installed inside the air inlet, but the air damper does not completely block the air inlet. A drive mechanism moves the air damper left and right within the air inlet. Thus, when the air damper mechanism is applied to a fresh air unit, the movement of the air damper can adjust the ratio of return air entering the return air inlet and the bypass air inlet, thereby adjusting the heat exchange between the return air and the fresh air, and achieving precise control of the fresh air unit's supply air temperature.

[0036] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure.

[0042] Combination Figure 1As shown, this embodiment of the disclosure provides a damper mechanism 10, including: a support frame 11, a drive mechanism 12, and a damper 13. The support frame 11 is a square frame that is closed on all four sides and hollow in the middle, with the hollow in the middle serving as an air inlet 111. The drive mechanism 12 is fixed to the support frame 11. The damper 13 is disposed at the air inlet 111, and the height of the damper 13 matches the height of the air inlet 111, while the length of the damper 13 is less than the length of the air inlet 111. Thus, when the left and right sides of the damper 13 are not in contact with the left and right sides of the inner frame 112 of the support frame 11, return air can pass through the left and right sides of the damper 13. The damper 13 is also connected to the drive mechanism 12 for transmission. Driven by the drive mechanism 12, the damper 13 can move left and right within the air inlet 111, thereby changing the proportion of return air passing through the sides of the damper 13.

[0043] Combination Figure 2 and Figure 3 As shown, when the damper mechanism 10 is applied to the fresh air unit 20, the return air inlet 22 of the return air duct and the bypass air inlet 23 of the bypass air duct correspond to the left and right sides of the air inlet 111 of the damper mechanism 10, respectively. The drive mechanism 12 drives the damper 13 to move left and right within the air inlet 111, and the blocking area of ​​the damper 13 on the return air inlet 22 and the bypass air inlet 23 will also change accordingly, thereby changing the proportion of return air entering the return air duct and the bypass air duct from both sides of the damper 13.

[0044] The damper mechanism 10 provided in this embodiment has an air inlet 111 on the support frame 11, and a damper 13 is provided inside the air inlet 111, which does not completely block the air inlet 111. The damper 13 is driven to move left and right within the air inlet 111 by the drive mechanism 12. Thus, when the damper mechanism 10 is applied to the fresh air unit 20, the movement of the damper 13 can adjust the ratio of return air entering the return air inlet 22 and the bypass air inlet 23, thereby adjusting the heat exchange between the return air and the fresh air, and achieving the purpose of precisely controlling the supply air temperature of the fresh air unit 20.

[0045] Optionally, the damper 13 has a plate-like structure.

[0046] Combination Figure 1 , Figures 4 to 6 As shown, the support frame 11 includes an inner frame 112 and an outer frame 113. It can be understood that the inner frame 112 is formed by connecting plates on the top, bottom, left, and right sides. The vertical direction of the inner frame 112 (relative to...) Figure 1 The upper and lower sides are respectively provided with sides facing left and right (relative to the upper and lower sides). Figure 1 The damper 13 extends into the groove 114. The upper and lower edges of the damper 13 are slidably disposed in the upper and lower grooves 114, respectively. In this way, the drive mechanism 12 can drive the damper 13 to move along the groove 114.

[0047] Optionally, the drive mechanism 12 includes a motor 121 and a transmission gear 122. The motor 121 is fixed to the support frame 11 via a connecting lug. The power output shaft of the motor 121 is disposed in the connecting hole of the transmission gear 122 to drive the transmission gear 122 to rotate. A rack 131 is provided on the damper 13, and the rack 131 meshes with the transmission gear 122. The transmission gear 122 rotates under the drive of the motor 121 and transmits the driving force to the damper 13 through the rack 131, thereby driving the damper 13 to move. In this way, the purpose of driving the damper 13 to move can be achieved through the gear and rack transmission method.

[0048] Alternatively, motor 121 is a stepper motor capable of forward and reverse rotation, which can drive damper 13 to move left and right.

[0049] Optionally, to ensure smooth movement of the damper 13 and prevent jamming during movement, two transmission gears 122 are used. Correspondingly, two racks 131 are also used, respectively located on the upper and lower edges of the damper 13. The motor 121 is mounted on the upper side of the support frame 11 via a connecting lug. One end of the transmission shaft 123 is rotatably passed through one connecting lug and connected to the power output shaft of the motor 121. The other connecting lug is located on the lower side of the support frame 11, and the other end of the transmission shaft 123 is rotatably connected to the other connecting lug. Both transmission gears 122 are mounted on the transmission shaft 123 and mesh with the two racks 131 respectively. In this way, the motor 121 can simultaneously drive both transmission gears 122 to rotate via the transmission shaft 123, thereby applying driving force to both the upper and lower sides of the damper 13, making the movement of the damper 13 more stable.

[0050] Optionally, racks 131 are respectively provided on the upper and lower edges of the same side of the damper 13. The part of the side of the support frame 11 corresponding to the rack 131, that is, the part corresponding to the groove 114, has a notch to expose part or all of a rack 131, so that the exposed part of the rack 131 can mesh with the corresponding transmission gear 122. In this way, the damper 13 is moved by the transmission gear 122.

[0051] Optionally, an opening sensor is provided on the support frame 11 to detect the opening of the damper 13.

[0052] See you again Figure 2 and Figure 3This disclosure provides a fresh air unit 20, including a housing 21 and a damper mechanism 10. The housing 21 contains a return air duct, a bypass air duct, and a fresh air duct. The damper mechanism 10 is disposed within the housing 21 and corresponds to the return air inlet 22 of the return air duct and the bypass air inlet 23 of the bypass air duct. The air inlet 111 of the support frame 11 is large enough to fully accommodate the return air inlet 22 and the bypass air inlet 23. The damper 13 is large enough to completely block the bypass air inlet 23. Thus, by driving the damper 13 to move left and right, the ratio of return air entering the return air inlet 22 to the bypass air inlet 23 can be changed, thereby adjusting the heat exchange between the return air and the fresh air, achieving precise control of the supply air temperature of the fresh air unit 20.

[0053] Optionally, in order to accommodate the installation space of the damper mechanism 10 within the housing 21, the support frame 11 and the damper 13 of the damper mechanism 10 are arc-shaped.

[0054] Optionally, the fresh air unit 20 also includes a processor that communicates with a temperature sensor and a motor to control the movement of the damper based on temperature.

[0055] Combination Figure 7 As shown, this disclosure provides a method for adjusting air supply, applied to the aforementioned fresh air unit, the method comprising:

[0056] S101, the processor calculates the first temperature difference between the return air temperature and the fresh air temperature.

[0057] S102, the processor determines the opening degree of the bypass vent based on the first temperature difference.

[0058] S103, the processor controls the movement of the damper according to the opening degree of the bypass vent.

[0059] Temperature sensors are installed at the fresh air inlet of the fresh air duct and the return air outlet of the return air duct to detect the fresh air temperature Tx and the return air temperature Th. The first temperature difference Δt1 = Th - Tx is calculated in real time. Since the return air temperature reflects the indoor temperature to some extent, the first temperature difference Δt1 can characterize whether the difference between the fresh air temperature and the indoor temperature is too large, and whether the introduction of fresh air will cause significant fluctuations in the indoor temperature. Based on this, the opening of the bypass vent is determined according to the first temperature difference Δt1 to determine the amount of return air directly discharged to the outside through the bypass vent. Then, the damper is moved based on the opening of the bypass vent to appropriately block the bypass vent, thereby controlling the amount of return air exchanging heat with the fresh air.

[0060] With the air supply adjustment method disclosed in this embodiment, a first temperature difference between the return air temperature and the fresh air temperature is first calculated to determine the degree of difference between the fresh air temperature and the indoor temperature. Then, the opening of the bypass air outlet is determined based on the first temperature difference, so as to determine the amount of return air directly discharged to the outside through the bypass air duct. Finally, the movement of the air damper is controlled based on the opening of the bypass air outlet to adjust the ratio of the opening of the return air inlet to the opening of the bypass air outlet, so as to control the amount of return air that exchanges heat with the fresh air, more accurately adjust the temperature of the fresh air delivered into the room, that is, adjust the air supply temperature, and avoid large fluctuations in the indoor temperature.

[0061] in conjunction with Figure 8 illustrated, an embodiment of the present disclosure provides another method for adjusting air supply, which is applied to the fresh air ventilator described above, and the method includes:

[0062] In S101, the processor calculates a first temperature difference between the return air temperature and the fresh air temperature.

[0063] In S102, the processor determines the opening of the bypass air outlet according to the first temperature difference.

[0064] In S113, the processor determines that the bypass air outlet is completely closed when the first temperature difference is greater than a first temperature threshold.

[0065] In S123, the processor determines that the bypass air outlet is completely open when the first temperature difference is less than a second temperature threshold.

[0066] In S133, when the first temperature difference is greater than or equal to the second temperature threshold and less than or equal to the first temperature threshold, the processor determines the opening ratio of the return air inlet to the bypass air outlet; and determines the opening of the bypass air outlet according to the opening ratio.

[0067] A first temperature threshold T1 and a second temperature threshold T2 are preset, where T1>T2. T1 and T2 are compared with Δt1.

[0068] If Δt1>T1, it indicates that the fresh air temperature is relatively low (the outdoor temperature is relatively low). To ensure a proper air supply temperature, the bypass air outlet is determined to be completely closed at this time. The air damper is controlled to move to completely block the bypass air outlet, so that all return air enters the return air duct and exchanges heat with the fresh air to maximize the increase of the fresh air temperature.

[0069] If Δt1<T2, it indicates that the fresh air temperature is relatively high (the outdoor temperature is relatively high). To ensure a proper air supply temperature, the bypass air outlet is determined to be completely open at this time. The air damper is controlled to move to completely avoid the bypass air outlet, so that as much return air as possible is directly discharged to the outside through the bypass air duct, and a small amount of return air enters the return air duct to exchange heat with the fresh air. Meanwhile, this can also extend the service life of the heat exchange core.

[0070] If T2≤Δt1≤T1, it indicates that the outdoor temperature and indoor temperature are not significantly different. Fully opening the bypass vent will lower the indoor temperature, but it will not necessarily cause it to close completely. Therefore, further determining the opening ratio between the return air vent and the bypass vent is necessary to ensure a suitable supply air temperature, reduce energy consumption, and increase the lifespan of the air core.

[0071] Thus, based on the first temperature difference, the degree of difference between the fresh air temperature and the indoor temperature is determined, the amount of return air that needs to exchange heat with the fresh air is determined, and then the required opening of the bypass vent is determined in order to accurately control the supply air temperature.

[0072] Optionally, the first temperature threshold is set to 5℃, and the second temperature threshold is set to 0℃.

[0073] Optionally, S133, the processor determines the opening degree of the bypass vent, including:

[0074] The processor calculates the second temperature difference between the supply air temperature and the return air temperature, and the fourth temperature difference between the fresh air temperature and the return air temperature.

[0075] The processor determines the opening degree of the bypass vent as a percentage of the ratio of the second temperature difference to the fourth temperature difference.

[0076] The preset air supply temperature Ts can be set by the user or by the air purifier itself.

[0077] The fresh air unit's air outlet is equipped with a temperature sensor to obtain the actual supply air temperature Tc. When T2≤Δt1≤T1, the opening of the bypass vent needs to be adjusted to dynamically adjust the mixing ratio α of fresh air and return air, so that the actual supply air temperature is close to the set supply air temperature Ts.

[0078] The relationship between the supply air temperature, fresh air temperature, and return air temperature is set as follows:

[0079] Ts=α×Tx+(1-α)×Th

[0080] After simplification, we can obtain: α=(Ts-Th) / (Tx-Th), where (Ts-Th) is the second temperature difference Δt2 and (Tx-Th) is the fourth temperature difference Δt4.

[0081] Then we have: α=Δt2 / Δt4

[0082] The percentage of the ratio α is determined as the opening degree K of the bypass vent: K = α × 100%.

[0083] For the above relational expression, there may be some special values in some cases, and the opening degree of the bypass vent is specifically as follows: when Tx-Th, the bypass vent is fully opened; when α<0, let α=0, and the bypass vent is fully closed; when α>1, let α=1, and the bypass vent is fully opened.

[0084] The opening sensor is used to detect whether the air damper has moved into position. When it moves into position, the motor is controlled to stop running.

[0085] In conjunction with Figure 9 as shown, an embodiment of the present disclosure provides another method for adjusting air supply, which is applied to the fresh air blower mentioned above, and the method comprises:

[0086] S101, the processor calculates a first temperature difference between the return air temperature and the fresh air temperature.

[0087] S102, the processor determines the opening degree of the bypass vent according to the first temperature difference.

[0088] S104, the processor corrects the opening degree of the bypass vent according to the set air supply temperature and the actual air supply temperature, so as to obtain the final opening degree of the bypass vent.

[0089] S106, the processor controls the movement of the air damper according to the final opening degree of the bypass vent.

[0090] After the opening degree of the bypass vent is determined based on the first temperature difference, the opening degree is an initial opening degree. In order to make the opening degree of the bypass vent more accurate, the actual air supply temperature feedback is introduced, and the opening degree of the bypass vent is corrected based on the set air supply temperature and the actual air supply temperature, so as to obtain the final opening degree of the bypass vent. The air damper moves into position according to the final opening degree.

[0091] Optionally, S106, in which the processor corrects the opening degree of the bypass vent according to the set air supply temperature and the actual air supply temperature, comprises:

[0092] The processor calculates a third temperature difference between the set air supply temperature and the actual air supply temperature.

[0093] The processor corrects the opening degree of the bypass vent according to the absolute value of the third temperature difference.

[0094] Calculate the absolute value of the third temperature difference |Δt3|=|Ts-Tc|. A third temperature threshold T3 is preset, and |Δt3| is compared with T3.

[0095] If |Δt3|<T3, it indicates that the actual air supply temperature is close to the set air supply temperature, and the opening degree of the bypass vent is not corrected to reduce the wear of the air damper mechanism.

[0096] If |Δt3|≥T3, it indicates that the difference between the actual supply air temperature and the set supply air temperature is relatively large, then the opening of the bypass air vent is corrected. The opening correction value ΔK = PID(Ts, Tc), and the final opening Kz = K + ΔK. Optionally, the larger |Δt3| is than T3, the greater the movement rate of the air damper, so as to quickly adjust the actual supply air temperature.

[0097] Optionally, the processor performs moving average filtering on the temperature signal to avoid noise interference.

[0098] Optionally, when the value of the fresh air temperature Tx is relatively extreme (e.g., too cold or too hot), the processor forcibly controls the bypass air vent to be completely closed.

[0099] Optionally, if the actual supply air temperature Tc cannot approach the set supply air temperature, that is, |Δt3| cannot be controlled to satisfy |Δt3|<T3, the processor triggers an alarm, or activates auxiliary heating or cooling.

[0100] In conjunction with Figure 10 as shown, an embodiment of the present disclosure provides an apparatus 100 for regulating supply air, comprising: a calculation module 101, a determination module 102, and a control module 103. The calculation module 101 is configured to calculate a first temperature difference between the return air temperature and the fresh air temperature. The determination module 102 is configured to determine the opening of the bypass air vent according to the first temperature difference. The control module 103 is configured to control the movement of the air damper according to the opening of the bypass air vent.

[0101] By adopting the apparatus 100 for regulating supply air provided in the embodiment of the present disclosure, the first temperature difference between the return air temperature and the fresh air temperature is first calculated to judge the degree of difference between the fresh air temperature and the indoor temperature. Then the opening of the bypass air vent is determined based on the first temperature difference, so as to determine the amount of return air directly discharged to the outdoors through the bypass air duct. Finally, the movement of the air damper is controlled based on the opening of the bypass air vent, so as to adjust the ratio of the opening of the return air vent to the opening of the bypass air vent, and further control the amount of return air that exchanges heat with the fresh air, so that the temperature of the fresh air sent into the room, that is, the supply air temperature, can be adjusted more accurately, and large fluctuations in the indoor temperature can be avoided.

[0103] Furthermore, the logical instructions in the aforementioned memory 112 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium.

[0104] The memory 112, as a computer-readable storage medium, can be used to store software programs and computer-executable programs, such as program instructions / modules corresponding to the methods in the embodiments of this disclosure. The processor 111 executes functional applications and data processing by running the program instructions / modules stored in the memory 112, that is, it implements the method for regulating air supply in the above embodiments.
