[0023] The preferred embodiments of the present application will be described below with reference to the accompanying drawings.

[0024] An embodiment of the present application provides a control method for a ventilation system.

[0025] Figure 1 It is a schematic diagram of an implementation of a ventilation system according to an embodiment of the present application.

[0026] exist Figure 1 In the figure, the solid lines between modules or devices represent refrigerant pipelines; in addition, the pipelines with arrows connecting the modules or devices are air pipelines; in addition, the dotted lines between modules or devices represent communication connections, which can be wired connections or wireless connections.

[0027] like Figure 1 As shown, the ventilation system 100 includes:

[0028] An air supply module 110, which is used to introduce air;

[0029] The air pipeline 120 connects the air supply module 110 and the indoor space

[0030] A plurality of air valves 130, which are respectively disposed at the air outlets of the plurality of air pipes 120, and are used to control the ventilation volume of each indoor space or each area of ​​the indoor space; and

[0031] The control module 140 controls each module in the ventilation system 100, including executing the control method of the embodiment of the present application.

[0032] In some embodiments, the air supply module 110 includes at least one of a fresh air processing device, a full heat exchange device (for example, with an internal circulation function or without an internal circulation function), and a ventilation device (for example, with an internal circulation function or without an internal circulation function), and the air supply module 110 has an air supply unit, and the air supply unit is, for example, a fan.

[0033] In some embodiments, the ventilation system of the present application may regulate multiple indoor spaces, and the air supply module 110 supplies air to the multiple indoor spaces through multiple air pipes 120. Figure 1 In the figure, two indoor spaces (space 1 and space 2) are taken as an example for description, however, the embodiment of the present application is not limited to two indoor spaces, and may also have more indoor spaces and set more air ducts for air supply.

[0034] In some embodiments, the indoor space that is the object of the ventilation system to be regulated may include multiple areas, and the air supply module 110 supplies air to the multiple areas of the indoor space through multiple air ducts 120 .

[0035] In some embodiments, the air duct 120 is an air inlet duct, and each air duct 120 corresponds to a different indoor space, or corresponds to a different area of ​​the indoor space.

[0036] In some embodiments, Figure 1 As shown, an air duct 121 serving as a return air duct may also be provided to centrally return air to each indoor space or each area and discharge the air to the outdoors.

[0037] like Figure 1 As shown, a plurality of air valves 130 are respectively disposed at the air outlets of the air ducts 120 to independently control the air flow output from each air outlet to each indoor space, that is, to independently control the ventilation volume.

[0038] In some embodiments, the actions of the air valve 130 may include opening, closing, and adjusting the opening angle.

[0039] For example, when the air valve 130 is closed, the air flow entering the indoor space corresponding to the air valve 130 is blocked; when the air valve 130 is opened, the air flow enters the indoor space smoothly; when the opening angle of the air valve 130 is adjusted, the flow rate of the air flow entering the indoor space can be adjusted.

[0040] In some embodiments, the air valve 130 may include a baffle, and the rotation angle of the baffle is controlled by a motor to allow the air flow in the air duct to pass through, partially pass through, or prevent the air flow from passing through.

[0041] Figure 2 Schematic diagram of the air valve of the embodiment of the present application. Figure 2 As shown in (A) in FIG. 1 , the air valve 130 includes a baffle 131. When the angle of the baffle 131 is 0 degrees, that is, when the baffle 131 is in a horizontal position, the air valve 130 is in an open state, and the air flow of the air pipeline 120 is in a smooth state; Figure 2 As shown in (B) in FIG. 1 , when the angle of the baffle 131 is 90 degrees, that is, when the baffle 131 is in a vertical position, the air valve 130 is in a closed state, which closes the entire air pipeline 120 and blocks the passage of air flow. In addition, when the angle of the baffle 131 is between 0 and 90 degrees, a portion of the air flow of the air pipeline 120 is blocked by the baffle 131.

[0042] In addition, if Figure 1 As shown, indoor units 150 are respectively installed in each indoor space. The dampers 130 are installed corresponding to the indoor units 150.

[0043] In some embodiments, the air valve 130 and the corresponding indoor unit 150 are in the same indoor space, or the air valve 130 and the corresponding indoor unit 150 process the air in the same indoor space (or the same area), that is, the air valve 130 and the corresponding indoor unit 150 have their air outlets in the same indoor space (or the same area).

[0044] In some embodiments, the air valve 130 is connected to the corresponding indoor unit 150 by at least one of a power supply connection and a communication connection, that is, the indoor unit 150 supplies power to the corresponding air valve 130, and / or the indoor unit 150 communicates with the corresponding air valve 130, for example, the indoor unit 150 sends a control instruction to the air valve 130, etc.

[0045] In the embodiment of the present application, the indoor space (or the area of ​​the indoor space), the indoor unit 150, the air duct 140 and the air valve 130 are corresponding. By controlling the air valve 130 corresponding to the indoor space, the flow rate of the air entering the indoor space (or the area) can be independently controlled, so that the ventilation volume of the indoor space (or the area) can be independently adjusted.

[0046] In some embodiments, part of the indoor space or the indoor space may not be provided with the air valve 130, that is, some of the indoor units 150 are not provided with the corresponding air valve 130.

[0047] In some embodiments, ventilation system 100 includes an air conditioning system.

[0048] The air conditioning system may be a commercial air conditioning system or a domestic air conditioning system.

[0049] In some embodiments, the air conditioning system may include at least one group of outdoor units and at least one indoor unit connected to each group of outdoor units. That is, the air conditioning system may include one or more groups of outdoor units, each group of outdoor units includes at least one outdoor unit; for a group of outdoor units, the group of outdoor units is connected to at least one indoor unit.

[0050] For example, an air conditioning system includes an outdoor unit and an indoor unit connected to the outdoor unit.

[0051] For example, the air conditioning system includes an outdoor unit and at least two indoor units connected to the outdoor unit.

[0052] For example, the air conditioning system includes at least two outdoor units and at least two indoor units connected to the at least two outdoor units.

[0053] For example, a group of outdoor units and at least one indoor unit connected to the group of outdoor units constitute a refrigerant system, or multiple groups of outdoor units and at least one indoor unit respectively connected to the multiple groups of outdoor units constitute multiple refrigerant systems. Thus, the air-conditioning system may include one refrigerant system or multiple refrigerant systems.

[0054] In some embodiments, the outdoor unit and the indoor unit may be air-conditioning equipment of various models, types, forms, and capacities.

[0055] For example, the indoor unit may be in the form of four-sided outlet, two-sided outlet, duct unit, ground outlet or skirting outlet; the outdoor unit may be in the form of single fan top outlet, double fan top outlet, single fan front outlet or double fan front outlet.

[0056] like Figure 1 As shown, for example, one outdoor unit 160 is connected to a plurality of indoor units 150 via a refrigerant pipe 170 .

[0057] In some embodiments, the control module 140 is also called a centralized control module, which performs centralized control on the ventilation system 100 .

[0058] In some embodiments, the control module 140 includes a controller, for example, the controller may be a centralized controller, a wired controller, a remote controller, an intelligent controller, etc. A user may issue instructions by operating the controller.

[0059] In some embodiments, the control module 140 may further include a gateway device that collects data from various modules and devices and generates a control instruction for the air valve 130 based on the data, i.e., an air valve control instruction. The air valve 130 opens, closes, and adjusts the opening angle of the air valve according to the air valve control instruction for the air valve.

[0060] For example, the control module 140 sends the air valve control instruction to the indoor unit 150 corresponding to the air valve 130. The indoor unit 150 sends the received air valve control instruction to the air valve 130 corresponding to the indoor unit 150. The air valve 130 opens, closes, adjusts the opening angle, etc. according to the air valve control instruction.

[0061] The specific control process of the air valve 130 will be described in detail in the following embodiments.

[0062] In some embodiments, the air valve control instruction includes identification information of the air valve and may also include identification information of the indoor unit corresponding to the air valve.

[0063] In some embodiments, the control module 140 includes a memory and a processor, wherein the memory stores a computer program; and the processor implements the control method of the embodiment of the present application when executing the computer program.

[0064] In some embodiments, Figure 1 As shown, the ventilation system 100 further includes: a detection module 180, which may include at least one of a temperature sensor and a humidity sensor. For example, at least one of the temperature and humidity of the indoor space and the temperature and humidity in the air duct 120 is detected by at least one of the temperature sensor and the humidity sensor in the detection module 180.

[0065] In some embodiments, the ventilation system may further include a humidity control module.

[0066] Figure 3 FIG. 1 is a schematic diagram of another embodiment of the ventilation system of the present application. Figure 3 As shown, the structure of the ventilation system 100' is mostly the same as that of the humidity control system 100 in Example 1. The difference from the ventilation system 100 is that the ventilation system 100' further includes:

[0067] The humidity control module 190 is disposed at the downstream side of the air supply module 110 , and is used to control the humidity of the air passing through the air supply module 110 .

[0068] In the embodiments of the present application, the “downstream side” refers to the downstream side in the air flow path, and the “upstream side” refers to the upstream side in the air flow path.

[0069] In some embodiments, the humidity control module 190 may be a dehumidification device, a humidification device, or a humidity control device having both humidification and dehumidification functions.

[0070] In some embodiments, the humidity control module 190 may perform humidification based on various humidification principles.

[0071] For example, the humidity control module performs humidification based on a wet film, or the humidity control module performs humidification based on waterless humidification, or the humidity control module performs humidification based on spray humidification, or the humidity control module performs humidification based on steam humidification.

[0072] In addition, if Figure 3 As shown, the refrigerant pipeline 170 is also connected to the humidity control module 190 .

[0073] In some embodiments, the control module 140 is connected to the indoor unit 150 via a wired connection; in addition, each indoor unit 150, between the indoor unit 150 and the outdoor unit 160, between the humidity control module 190 and the indoor unit 150, and between the air supply module 110 and the humidity control module 190 can all be connected via a wired connection.

[0074] exist Figure 1 and Figure 3 In the ventilation system shown, the plurality of air valves 130 are respectively arranged at the air outlets of the plurality of air pipes 120, but the air valves 130 may also be arranged at other positions on the downstream side of the ventilation module 110, for example, the plurality of air valves 130 may be respectively arranged in the plurality of air pipes 120. Figure 1 In the ventilation system 100 shown in FIG. 1 , a plurality of air valves 130 may also be respectively disposed at a plurality of air outlets of the ventilation module 110. Figure 3 In the ventilation system 100 ′ shown, a plurality of air valves 130 may also be respectively disposed at a plurality of air outlets of the humidity control module 190 .

[0075] The control method of the embodiment of the present application is described in detail below.

[0076] Figure 4 FIG. 1 is a block diagram of a control method for a ventilation system according to an embodiment of the present application. Figure 4 As shown, the method includes:

[0077] Step 401: When the preset conditions are met, the air valve is controlled to first close and then open.

[0078] For example, the damper is Figure 1 or Figure 3 One or more air valves 130 in.

[0079] In some embodiments, the closing action refers to a fully closing action, and the opening action refers to a fully opening action.

[0080] In some embodiments, when the air valve is fully closed, it is first closed to an over-closed position and then restored to the fully closed position; when the air valve is fully opened, it is first opened to an over-opened position and then restored to the fully open position. In this way, it can ensure that the air valve remains in the fully open position, further improving the accuracy and reliability of adjusting the air valve to the reference position.

[0081] For example, the "over-closed position" means that in the process of controlling the air valve to close, the air valve is controlled to continue to close by a preset offset on the basis of full closure; the "over-open position" means that in the process of controlling the air valve to open, the air valve is controlled to continue to open by a preset offset on the basis of full opening.

[0082] For example, when controlling the baffle angle of the air valve by rotating the motor, controlling the air valve to the "over-closed position" means controlling the rotation amount of the motor to be the rotation amount required for "fully closed" plus an offset. Similarly, controlling the air valve to the "over-open position" means controlling the rotation amount of the motor to be the rotation amount required for "fully open" plus an offset.

[0083] The offset of over-opening relative to fully opening and the offset of over-closing relative to fully closing may be the same or different. In addition, the specific value of the offset may be set according to actual conditions.

[0084] In some embodiments, the preset condition includes the ventilation system being powered on. For example, when the ventilation system 100 or 100' is powered on, all the air valves 130 are controlled to first be fully closed and then fully opened, so that the air valves 130 are controlled at a uniform and accurate reference position, and the air valves 130 can be precisely controlled based on the reference position, for example, adjusted to a specific opening angle based on the fully opened position; thereby, the ventilation volume of each indoor space or each area can be precisely controlled, and the user's comfort can be improved.

[0085] In some embodiments, the preset condition also includes receiving an instruction to adjust the opening of the air valve.

[0086] For example, when the air valve is in a fully open state, when the air valve receives an instruction to adjust the opening, it is directly adjusted to the angle indicated by the opening adjustment instruction.

[0087] For another example, when the air valve is in a fully closed state, when the air valve receives an instruction to adjust the opening, it first performs a fully open action and then adjusts to the angle indicated by the opening adjustment instruction.

[0088] For another example, when the air valve is in the state of opening angle 1, when the air valve receives an instruction to adjust the opening, it first performs a full opening action, and then adjusts to angle 2 indicated by the opening adjustment instruction, wherein angle 1 and angle 2 are different angles, and angle 1 and angle 2 are angles between 0-90 degrees.

[0089] Figure 5 FIG. 1 is a flow chart of a specific implementation method of the ventilation system control method of the present application embodiment. Figure 5 As shown, the method includes:

[0090] Step 501: Check whether the ventilation system is powered on; if it is judged as "yes", go to step 502; if it is judged as "no", return;

[0091] Step 502: Control the air valve to fully close;

[0092] Step 503: Control the air valve to fully open;

[0093] Step 504: determine whether the air valve receives an opening adjustment instruction, i.e., an angle indication; if the determination is "yes", proceed to step 505; if the determination is "no", return;

[0094] Step 505: Control the air valve to adjust to the angle indicated by the opening adjustment instruction;

[0095] Step 506: Determine whether the air valve receives a closing instruction; if it is determined to be "yes", proceed to step 507; if it is determined to be "no", return;

[0096] Step 507: Control the air valve to fully close;

[0097] Step 508: Determine whether the air valve receives an opening adjustment instruction, i.e., an angle indication; if the judgment is "yes", proceed to step 509; if the judgment is "no", return;

[0098] Step 509: Control the air valve to fully open first;

[0099] Step 510: Control the air valve to adjust to the angle indicated by the opening adjustment instruction.

[0100] In this way, when the ventilation system is powered on, the air valve is first closed and then opened to ensure that the air valve is in a uniform and accurate initial position, so as to achieve precise control of the air valve; when the air valve is in a fully open state or opened to a certain angle, when the opening angle of the air valve needs to be adjusted, that is, when the air valve receives an opening adjustment instruction, it is directly adjusted to the angle indicated by the instruction; and when the air valve is in a fully closed state, when the air valve needs to be adjusted to a certain angle, that is, when the air valve receives an opening adjustment instruction, the air valve is first controlled to be fully open, that is, adjusted to the accurate initial position, and then adjusted to the angle indicated by the instruction, which can ensure the accuracy of the adjustment angle and, in addition, can also extend the service life of the air valve.

[0101] Figure 6 FIG. 1 is an example diagram of the control process of the air valve in the embodiment of the present application. Figure 6 As shown, when the system is powered on, the air valve is controlled to first fully open, wherein it is first controlled to be over-opened and then restored to fully open; when an angle indication is received, it is adjusted to the indicated angle; when a fully open indication is received, it is first over-opened and then restored to fully open; when a fully closed indication is received, it is first over-closed and then restored to fully closed; when a fully open indication is received, it is first over-opened and then restored to fully open. In addition, the angle of the damper of the air valve can be controlled by the driving pulse of the motor, and when the air valve is controlled to be over-opened or over-closed, a pulse reset is performed to restore to the fully open or fully closed angle.

[0102] Figure 7 FIG. 2 is another example diagram of the control process of the air valve in the embodiment of the present application. Figure 7 As shown, when the air valve is in the open state, upon receiving an angle indication, the opening angle is modulated to the indicated angle; upon receiving a fully closed indication, it is first over-closed and then restored to fully closed; in the fully closed state, when an angle indication is received, it is first fully opened, that is, it is first over-opened and then restored to fully open, and then adjusted to the indicated angle.

[0103] In this way, the consistency of the reference when the air valve is adjusted in angle as well as the accuracy and reliability of the angle adjustment can be ensured.

[0104] In some embodiments, a limit switch may be provided at the closed position of the air valve to monitor whether the air valve is operating normally. For example, motor failure, limit switch failure, wire breakage, mechanical locking of the drive system, foreign matter biting on the shock absorber, etc. may cause abnormal operation of the air valve.

[0105] like Figure 4 As shown, for example, the method further includes:

[0106] Step 402: Determine whether the air valve is abnormal based on the output signal of the limit switch set at the fully closed position of the air valve.

[0107] For example, the limit switch is set near the damper of the air valve reaching the fully closed position. When the air valve is fully closed, the damper contacts the limit switch, the limit switch short-circuits and outputs a signal. After the damper separates from the limit switch, the limit switch is disconnected and no longer outputs a signal.

[0108] In some embodiments, when the air valve receives a full closing instruction and the limit switch has no output signal after a first preset time, the air valve is determined to be abnormal; when the air valve receives an opening instruction and the output signal of the limit switch has no change after a second preset time, the air valve is determined to be abnormal. In this way, it is possible to monitor in real time whether the operation of the air valve is normal based on the output signal of the limit switch, so that faults can be discovered in time, the operation of the air valve can be ensured, user needs can be met, and system reliability and user comfort can be improved.

[0109] The first preset time and the second preset time can be set according to actual conditions.

[0110] In some embodiments, the position (angle) of the damper is controlled by the pls value of the motor.

[0111] Figure 8 is an example diagram of judging the abnormality of the air valve according to the embodiment of the present application. Figure 8 As shown, when the air valve receives the full closing command, it starts to close, that is, it first reaches the over-closing position and then returns to the full closing position. When the duration of reaching or exceeding the full closing pls exceeds 2 seconds and the limit switch (SW) is disconnected, that is, there is no output signal, it is determined that the air valve is operating abnormally;

[0112] In addition, when the air valve receives an opening instruction (for example, including a full opening indication or an angle indication), it starts the opening action, that is, it first reaches the over-open position and then returns to the fully open position. Among them, when the duration of less than the fully open pls exceeds 2 seconds and the limit switch (SW) is short-circuited, that is, the output signal, it is determined that the air valve is operating abnormally.

[0113] According to the above embodiment, in the ventilation system, by providing an air valve in the air duct or at the air outlet connecting the ventilation module and each indoor space or each area, the ventilation volume of each indoor space or each area can be independently controlled; and when the preset conditions are met, the air valve is controlled to first close and then open, thereby controlling the air valve to a uniform and accurate reference position, and the air valve can be accurately controlled based on the reference position, thereby achieving accurate control of the ventilation volume of each indoor space or each area, thereby improving the reliability of the system and the comfort of the users.

[0114] The embodiment of the present application also provides a computer-readable program, wherein when the program is executed, the program enables the computer to execute the control method of the ventilation system described in the embodiment of the present application.

[0115] An embodiment of the present application further provides a computer-readable storage medium, wherein the storage medium stores a computer program, and the computer-readable program enables a computer to execute the control method of the ventilation system described in the embodiment of the present application.
