Description

Technical Field

[0001] The present application relates to the field of ventilation regulation, and in particular to a ventilation system and a control method of the ventilation system. Background Art

[0002] With the continuous advancement of science and technology and the improvement of living standards, people have higher and higher requirements for living environment. Among them, indoor carbon dioxide concentration, temperature, humidity and other air quality parameters are important indicators for measuring living environment. For example, in winter, due to the low outdoor temperature, indoor windows need to be closed, resulting in poor indoor air circulation. Therefore, a ventilation system is needed to ventilate the indoor space; for another example, in summer, due to the high temperature and humidity, the indoor space is relatively hot and stuffy. Therefore, a ventilation system is also needed to ventilate the indoor space.

[0003] Typically, in a ventilation system, air is introduced into a plurality of indoor spaces by using an air supply module, and the ventilation volume of the plurality of indoor spaces can be uniformly adjusted by adjusting the air volume of the ventilation module.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Summary of the invention

[0005] The inventors have discovered that in existing ventilation systems, the ventilation volumes of multiple indoor spaces are uniformly adjusted. However, the specific environmental conditions of different indoor spaces may be different. In addition, users in different indoor spaces may have different requirements for the adjustment of indoor ventilation volumes. Therefore, it is necessary to independently adjust the ventilation volume of each indoor space.

[0006] Moreover, independently adjusting the ventilation volume of an indoor space may cause changes in the ventilation volume of other indoor spaces. For example, when the air duct corresponding to an indoor space is closed, the overall ventilation volume introduced by the air supply module remains unchanged, which will cause the ventilation volume of other indoor spaces to increase, thereby increasing the noise generated by ventilation in other indoor spaces and reducing user comfort. For another example, when the air duct corresponding to an indoor space is opened, the overall ventilation volume introduced by the air supply module remains unchanged, thereby causing the ventilation volume of other indoor spaces to decrease, thereby reducing the air quality of other indoor spaces and also reducing user comfort.

[0007] In order to solve at least one of the above problems, the embodiments of the present application provide a ventilation system and a control method of the ventilation system. The ventilation volume of different indoor spaces or different areas of indoor spaces can be adjusted independently, and when the ventilation volume of some indoor spaces or some areas is adjusted, the change of the ventilation volume of other indoor spaces or other areas can be avoided, thereby avoiding the increase of noise caused by ventilation of other indoor spaces or other areas, avoiding the impact on other users, and thus ensuring the comfort and use experience of users.

[0008] According to a first aspect of an embodiment of the present application, a control method for a ventilation system is provided, wherein the ventilation system comprises: an air supply module, which is used to introduce air; a plurality of air valves, which are respectively arranged in a plurality of air ducts connected to the air supply module or at air outlets of the plurality of air ducts, and are used to control the ventilation volume of each indoor space or each area of ​​the indoor space; the method comprises: adjusting the air volume of the air supply module and at least one of the openings of other air valves according to the opening rate of the air valve in the ventilation system while adjusting the opening of at least one air valve.

[0009] According to the second aspect of the embodiment of the present application, a ventilation system is provided, characterized in that the ventilation system includes: an air supply module, which is used to introduce air; an air duct, which connects the air supply module and the indoor space; a plurality of air valves, which are respectively arranged in the plurality of air ducts connected to the air supply module or at the air outlets of the plurality of air ducts, for controlling the ventilation volume of each indoor space or each area of ​​the indoor space; and a control module, which executes the control method described in the first aspect of the embodiment of the present application.

[0010] One of the beneficial effects of the embodiments of the present application is that: by providing multiple air valves in multiple air ducts connected to the air supply module or at the air outlets of multiple air ducts, the ventilation volume of different indoor spaces or different areas of indoor spaces can be independently adjusted; and when the opening degree of at least one air valve is adjusted, the air volume of the air supply module and at least one of the opening degrees of other air valves are adjusted according to the opening rate of the air valve in the ventilation system. While adjusting the ventilation volume of part of the indoor space or part of the area, the change of the ventilation volume of other indoor spaces or other areas can be avoided, thereby avoiding the increase of noise caused by the ventilation of other indoor spaces or other areas, avoiding the impact on other users, and thus ensuring the user's comfort and usage experience.

[0022] The preferred embodiments of the present application will be described below with reference to the accompanying drawings.

[0023] Example 1

[0024] An embodiment of the present application provides a method for controlling 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 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] An air pipeline 120 connecting the air supply module 110 and the indoor space;

[0030] A plurality of air valves 130, which are respectively disposed in a plurality of air pipes 120 connected to the air supply module 110 or at 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 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.

[0039] In some embodiments, the air flow output from each air outlet to each indoor space is independently controlled by adjusting the opening of the air valve.

[0040] In some embodiments, adjusting the opening of the air valve includes: the opening range of the air valve is 0 degrees to 90 degrees; wherein, when the opening of the air valve is 0 degrees, the air valve is in a fully open state; when the opening of the air valve is greater than 0 degrees and less than 90 degrees, the air valve is in a partially open state; when the opening of the air valve is 90 degrees, the air valve is in a fully closed state.

[0041] For example, when the air valve is in a fully closed state, the air flow entering the indoor space corresponding to the air valve is blocked; when the air valve is in an open state, the air flow is allowed to smoothly enter the indoor space; and when the opening of the air valve is adjusted, the flow rate of the air flow entering the indoor space can be adjusted.

[0042] In some embodiments, the air supply module 110 controls the air volume by adjusting the opening of the air valve 130. For example, the fan in the air supply module 110 is controlled.

[0043] Therefore, by adjusting the opening of the air valve, the air exchange volume of the corresponding indoor space can be adjusted, which can further improve the accuracy of air exchange volume adjustment for different indoor spaces or different areas and improve user comfort.

[0044] The specific adjustment process of the air valve 130 will be described in detail in the following embodiments.

[0045] 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.

[0046] 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).

[0047] 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.

[0048] 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.

[0049] In some embodiments, part of the indoor space or the indoor space may not be provided with the air valve 130, that is, some indoor units 150 are not provided with corresponding air valves 130.

[0050] Figure 2 It is a simplified schematic diagram of the ventilation system of an embodiment of the present application. Figure 2 Only the arrangement of the air valve in the ventilation system of the embodiment of the present application is briefly shown, and other structures are similar to those of the present invention. Figure 1 The structure of the ventilation system 100 shown is the same and will not be described again herein.

[0051] For example, Figure 2 As shown, the ventilation system of the present application may include a plurality of indoor spaces, and the air supply module 110 supplies air to the plurality of indoor spaces through a plurality of air pipes 120, and Figure 2 In the figure, five indoor spaces (space 1 to space 5) are taken as examples for explanation, wherein the indoor units 150 corresponding to space 1 to space 4 are provided with air valves 130, while the indoor units 150 corresponding to space 5 are not provided with air valves 130; during the operation of the ventilation system, the air valves 130 corresponding to space 1 to space 4 can be in a fully open state, a partially open state, and a fully closed state, respectively, and air is introduced into the corresponding spaces according to the states of the air valves 130 corresponding to space 1 to space 4; and the air duct 120 corresponding to space 5 continuously introduces air into space 5.

[0052] For example, the air valve 130 in space 1-space 2 is in a fully open state, the air valve 130 in space 3 is in a partially open state, and the air valve 130 in space 4 is in a fully closed state. Thus, the ventilation volume of each indoor space or each area can be independently controlled.

[0053] In some embodiments, ventilation system 100 also includes an air conditioning system.

[0054] The air conditioning system may be a commercial air conditioning system or a domestic air conditioning system.

[0055] 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.

[0056] For example, an air conditioning system includes an outdoor unit and an indoor unit connected to the outdoor unit.

[0057] For example, the air conditioning system includes an outdoor unit and at least two indoor units connected to the outdoor unit.

[0058] 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.

[0059] 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.

[0060] In some embodiments, the outdoor unit and the indoor unit may be air-conditioning equipment of various models, types, forms, and capacities.

[0061] 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.

[0062] 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 .

[0063] In some embodiments, the control module 140 is also called a centralized control module, which performs centralized control on the ventilation system 100 .

[0064] 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.

[0065] In some embodiments, the control module 140 generates a damper control instruction to adjust the opening of at least one damper.

[0066] 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 adjusts the opening of the air valve according to the air valve control instruction for the air valve.

[0067] In some embodiments, the control module 140 sends the air valve control instruction to the indoor unit 150 corresponding to the air valve 130 , and the indoor unit 150 sends the received air valve control instruction to the air valve 130 corresponding to the indoor unit 150 .

[0068] In some embodiments, at least one air valve 130 adjusts the opening of the at least one air valve 130 according to an air valve control instruction for the at least one air valve 130 .

[0069] For example, the control module 140 sends the air valve control instruction to the indoor unit 150 corresponding to the air valve 130, and 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 adjusts the opening and other actions according to the air valve control instruction.

[0070] The specific control process of the air valve 130 will be described in detail in the following embodiments.

[0071] 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.

[0072] 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.

[0073] 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, by detecting at least one of the temperature sensor and the humidity sensor in the detection module 180, at least one of the temperature and humidity of the indoor space and the temperature and humidity in the air duct 120 is detected.

[0074] In some embodiments, the ventilation system may further include a humidity control module.

[0075] 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 ventilation system 100 in Example 1. The difference from the ventilation system 100 is that the ventilation system 100' further includes:

[0076] 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 .

[0077] Therefore, since the air flow controlled by the air valve 130 has been humidified by the humidity control module 190, the air flow into the indoor space can be blocked, flowed in and flowed by the action of the air valve, so that the air humidity in the indoor space can be independently adjusted.

[0078] 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.

[0079] 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.

[0080] In some embodiments, the humidity control module 190 can perform humidification based on various humidification principles.

[0081] 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.

[0082] In addition, if Figure 3 As shown, the refrigerant pipeline 170 is also connected to the humidity control module 190 .

[0083] 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.

[0084] exist Figure 1 and Figure 3In 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 .

[0085] In some embodiments, the air supply module 110 obtains the opening information of the air valve 130 from the humidity control module 190 , or may also obtain the opening information of the air valve 130 from the control module 140 .

[0086] Based on the above-mentioned ventilation system 100, the control method of the embodiment of the present application is described in detail below.

[0087] 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:

[0088] Step 401: When adjusting the opening of at least one air valve, adjust the air volume of the air supply module and at least one of the openings of other air valves according to the opening rate of the air valve in the ventilation system.

[0089] For example, the damper is Figure 1 or Figure 3 One or more air valves 130 in.

[0090] Therefore, by setting multiple air valves in multiple air ducts connected to the air supply module or at the air outlets of multiple air ducts, the ventilation volume of different indoor spaces or different areas of indoor spaces can be independently adjusted; and when the opening degree of at least one air valve is adjusted, the air volume of the air supply module and at least one of the opening degrees of other air valves are adjusted according to the opening rate of the air valve in the ventilation system. While adjusting the ventilation volume of part of the indoor space or part of the area, the change of the ventilation volume of other indoor spaces or other areas can be avoided, thereby avoiding the increase of noise caused by ventilation of other indoor spaces or other areas, avoiding the impact on other users, thereby ensuring the user's comfort and usage experience.

[0091] In some embodiments, adjusting the opening of the air valve includes: the opening range of the air valve is 0 degrees to 90 degrees; wherein, when the opening of the air valve is 0 degrees, the air valve is in a fully open state; when the opening of the air valve is greater than 0 degrees and less than 90 degrees, the air valve is in a partially open state; when the opening of the air valve is 90 degrees, the air valve is in a fully closed state.

[0092] For example, when the air valve is in a fully closed state, the air flow entering the indoor space corresponding to the air valve is blocked; when the air valve is in an open state, the air flow is allowed to smoothly enter the indoor space; and when the opening of the air valve is adjusted, the flow rate of the air flow entering the indoor space can be adjusted.

[0093] Thus, by adjusting the opening of the air valve, the air exchange volume of the corresponding indoor space can be adjusted, which can further improve the accuracy of air exchange volume adjustment for different indoor spaces or different areas, and improve user comfort. In some embodiments, the opening rate of the air valve in the ventilation system is calculated based on the number of open air outlets of the air duct and the number of indoor units included in the ventilation system.

[0094] In some embodiments, the air valves in the ventilation system are arranged corresponding to the indoor units, and the opening rate of the air valves in the ventilation system is equal to the number of opened air valves divided by the number of indoor units.

[0095] In some implementations, the number of indoor units is the number of indoor units bound to the ventilation system.

[0096] For example, Figure 1 As shown, there are two indoor units in two indoor spaces and two corresponding air valves are set. When the air valve of space 1 is fully closed and the air valve of space 2 is fully opened, the opening rate of the air valve in the ventilation system = 1 (1 air valve is open) / 2 (2 indoor units) = 50%.

[0097] In some embodiments, the number of open air outlets of the air duct is the sum of the number of air outlets provided with air valves and with open air valves and the number of air outlets not provided with air valves.

[0098] In some embodiments, the air valves and indoor units in the ventilation system are not set correspondingly; the opening rate of the air valves in the ventilation system is equal to the sum of the number of air outlets with air valves and open air valves and the number of air outlets without air valves divided by the number of indoor units.

[0099] For example, in the ventilation system, some air pipelines are provided with corresponding air valves, while some air pipelines are not provided with corresponding air valves. During the operation of the ventilation system, the air pipelines without air valves are all open air pipelines by default.

[0100] For example, Figure 2 As shown, there are five indoor units in five indoor spaces, and corresponding air valves are set at the air outlets of the air ducts corresponding to space 1 to space 4, and no air valve is set at the air outlet of the air duct corresponding to space 5. When the air valves of space 1-2 are in a fully closed state and the air valves of space 3-4 are in a fully opened or partially opened state, the opening rate of the air valves in the ventilation system = 3 (2 air valves are opened + 1 air duct is not set with an air valve) / 5 (5 indoor units) = 60%.

[0101] In some embodiments, the opening rate of the air valve in the ventilation system is also called the opening area rate of the air valve. For example, the opening area rate of the air valve refers to the ratio of the sum of the current opening areas of all the air valves in the ventilation system to the sum of the maximum opening areas of all the air valves.

[0102] In some embodiments, the opening of each air valve can vary between 0 degrees and 90 degrees, and the diameters of each air duct may be different or not exactly the same. In this case, the opening rate of the air valve in the ventilation system is also calculated based on the opening of each air valve and the diameter of each air duct.

[0103] In some embodiments, the opening of the air valves provided at the outlets of the air ducts corresponding to the various indoor spaces and the diameters of the air ducts may be different, and the opening rate of the air valves in the ventilation system may be calculated based on the opening of the air valves and the diameters of the air ducts corresponding to the various indoor spaces.

[0104] For example, the opening range of the air valve is 0°-90°, and the pipe diameter can include 100mm, 150mm, and 200mm.

[0105] For example, still Figure 1 Taking an example to illustrate, the opening degree of the wind valve 150 in space 1 is 60°, and the corresponding opening percentage is (90°-60°) / 90°≈33.3%, and the diameter of the air pipe in space 1 is 150 mm; the opening degree of the wind valve 150 in space 2 is 45°, and the corresponding opening percentage is (90°-45°) / 90°=50%, and the diameter of the air pipe in space 2 is 150 mm; the opening rate of the wind valve in the ventilation system = (the area of ​​the air pipe corresponding to space 1 × the percentage of the air valve opening corresponding to space 1 + the area of ​​the air pipe corresponding to space 2 × the percentage of the air valve opening corresponding to space 2) / (the area of ​​the air pipe corresponding to space 1 + the area of ​​the air pipe corresponding to space 2) = 41.5%.

[0106] Therefore, by adjusting the opening of the air valve, the air exchange volume of the corresponding indoor space can be adjusted, which can further improve the accuracy of air exchange volume adjustment for different indoor spaces or different areas and improve user comfort.

[0107] In some embodiments, the air volume of the air supply module is adjusted by adjusting the number of revolutions of the motor of the ventilation module.

[0108] In some embodiments, the number of motor revolutions of the ventilation module is proportional to the air volume of the air supply module, and the air volume of the air supply module increases as the number of motor revolutions of the ventilation module increases.

[0109] In some embodiments, the device model of the ventilation module corresponds to the level of the motor rotation number and to the maximum air volume of the air supply module.

[0110] For example, the maximum air volume of the air supply module corresponding to motor rotation levels 1-3 is: 150m 3 / h (cubic meters / hour), 250m 3 / h, 350m 3 / h; and the equipment model corresponding to the first ventilation module (for example, referred to as model 1), the equipment model of the second ventilation module (for example, referred to as model 2), and the equipment model of the third ventilation module (for example, referred to as model 3).

[0111] For example, the device model of the ventilation module also includes whether the ventilation module includes a return air duct. For example, when the ventilation module does not include a return air duct, the device model of the ventilation module corresponds to a standard ventilation module; for example, when the ventilation module includes a return air duct, the device model of the ventilation module corresponds to an advanced ventilation module.

[0112] In some implementations, the motor revolution number is multiplied by a correction coefficient to obtain an adjusted motor revolution number.

[0113] For example, the correction coefficient ranges from 0.5 to 1; the maximum air volume corresponding to motor speed 1 is 150m 3 / h, the correction coefficient is 0.8, and the corresponding air volume after the adjustment of the motor rotation number is: 120m 3 / h.

[0114] In some implementations, the correction coefficient is determined according to an opening rate of a damper in the ventilation system.

[0115] In some embodiments, the correction coefficient is determined according to the device model of the ventilation module.

[0116] In some embodiments, the correction coefficient is determined according to the operating gear of the ventilation module.

[0117] For example, the operation gears of the ventilation module are divided into three gears: ultra-high, high, and low.

[0118] For example, Table 1 shows an example diagram of the relationship between the opening rate of the air valve in the ventilation system and the correction coefficient and the equipment model of the ventilation module for a standard ventilation module whose operating gear is at an ultra-high gear.

[0119] Table 1

[0120]

[0121] For example, Table 2 shows an example diagram of the relationship between the opening rate of the air valve in the ventilation system and the correction coefficient and the equipment model of the ventilation module for a standard ventilation module when the operation gear of the ventilation module is at a high gear.

[0122] Table 2

[0123]

[0124] For example, Table 3 shows an example diagram of the relationship between the opening rate of the air valve in the ventilation system and the correction coefficient and the equipment model of the ventilation module for a standard ventilation module when the operation gear of the ventilation module is at a low gear.

[0125] Table 3

[0126]

[0127] For example, the data in Tables 1-3 are only examples. The embodiments of the present application are not limited to the use of the specific data shown in Tables 1-3, and other data may also be used. The present application does not limit this.

[0128] In some embodiments, when the equipment models of the ventilation modules are the same and the opening rates of the air valves in the ventilation systems are the same, different operating gears of the ventilation modules correspond to different correction coefficients.

[0129] For example, as shown in Table 1 and Table 2, when the "opening rate of the air valve" is 70%, it corresponds to a row of "60~80% (excluding 80%)" in Table 1. For "Model 1", at the super high position, the correction coefficient is: "0.9"; Correspondingly, it corresponds to a row of "50~100%" in Table 2. For "Model 1", at the super high position, the correction coefficient is: "1".

[0130] In some embodiments, when the equipment models of the ventilation modules are the same and the opening rates of the air valves in the ventilation system are the same, different operating gears of the ventilation modules may correspond to the same correction coefficient.

[0131] For example, as shown in Table 2 and Table 3, when the "opening rate of the air valve" is 70%, it corresponds to the row of "50~100%" in Table 2. For "Model 1", at the super high position, the correction coefficient is: "1"; Correspondingly, it corresponds to the row of "30~100%" in Table 3. For "Model 1", at the super high position, the correction coefficient is: "1".

[0132] In some embodiments, when adjusting the opening of at least one air valve, the opening of at least one other air valve that is opened is adjusted according to the opening rate of the air valve in the ventilation system, while keeping the number of motor revolutions of the air supply module unchanged.

[0133] For example, Figure 1 As shown, there are two indoor units in two indoor spaces and two corresponding air valves are set. For example, during the initial operation of the ventilation system, the opening of the air valve in space 1 is 30°, the opening of the air valve in space 2 is 60°, and according to the calculation method of the opening rate of the air valve in the ventilation system in the aforementioned application, the opening rate of the air valve in the ventilation system is obtained to be 50%; for example, when the opening of the air valve in space 2 is adjusted to 30°, the opening rate of the air valve in the ventilation system is kept at 50% and the number of motor revolutions of the air supply module remains unchanged, and the opening of the air valve in space 1 is adjusted from 30° to 60°.

[0134] Therefore, by controlling the opening of the air valves in the space respectively, the ventilation volume of different indoor spaces or different areas of the indoor space can be adjusted independently; and when the opening of at least one air valve is adjusted, the opening of other air valves is adjusted according to the opening rate of the air valve in the ventilation system, so that while adjusting the ventilation volume of a specific indoor space or a specific area, drastic changes in the ventilation volume of other indoor spaces or other areas can be avoided, and the noise generation can be reduced, thereby improving the user's comfort and usage experience.

[0135] In some embodiments, when the opening degree of at least one air valve is adjusted, the opening degrees of other air valves that are opened are kept unchanged according to the opening rates of the air valves in the ventilation system, and the air volume of the air supply module is adjusted.

[0136] For example, Figure 1As shown, there are two indoor units in two indoor spaces and two corresponding air valves are set. For example, during the initial operation of the ventilation system, the opening of the air valve in space 1 is 30°, the opening of the air valve in space 2 is 60°, and according to the calculation method of the opening rate of the air valve in the ventilation system in the present application, the opening rate of the air valve in the ventilation system is obtained = 50%; for example, when the opening of the air valve in space 1 is adjusted to 60°, the opening of the air valve in space 2 is maintained at 60°, and the opening rate of the air valve = 33.3%. For example, according to the correction coefficient corresponding to "Model 1" in Table 1, the correction coefficient in the ventilation system is adjusted from 0.8 to 0.7.

[0137] Therefore, by controlling the opening of the air valves in the space respectively, the ventilation volume of different indoor spaces or different areas of the indoor space can be adjusted independently; and when the opening of at least one air valve is adjusted, the air volume of the air supply module is adjusted according to the opening rate of the air valve in the ventilation system. While adjusting the ventilation volume of part of the indoor space or part of the area, the change of the ventilation volume of other indoor spaces or other areas can be avoided, thereby avoiding the increase of noise caused by ventilation in other indoor spaces or other areas, avoiding the impact on other users, thereby ensuring the user's comfort and usage experience.

[0138] In some embodiments, when the opening rates of the air valves in the ventilation system are the same, different operating gears of the ventilation module correspond to different adjustment values ​​of the motor revolutions.

[0139] In some embodiments, the method further includes: determining an opening rate of an air valve in the ventilation system according to the air volume of the air supply module.

[0140] For example, before executing the above step 401, the opening rate of the air valve in the ventilation system is determined based on the air volume of the air supply module. For example, the determined opening rate of the air valve in the ventilation system is the initial opening rate of the air valve, such as the initial opening angle of the air valve determined before adjusting the opening of at least one air valve.

[0141] Figure 5 is a flowchart of a specific method for implementing step 401 in an embodiment of the present application. For example, Figure 5 The specific process of "while adjusting the opening of at least one air valve, keeping the number of motor revolutions of the air supply module unchanged according to the opening rate of the air valve in the ventilation system, and adjusting the opening of at least one of the other opened air valves" is shown.

[0142] like Figure 5 As shown, the method includes:

[0143] Step 501: Start; for example, during the initial operation of the ventilation system, the opening of the air valve of space 1 is 30°, and the opening of the air valve of space 2 is 60°;

[0144] Step 502: adjusting the opening of a damper; for example, adjusting the opening of the damper of space 2 to 30°;

[0145] Step 503: Keep the motor revolution number of the air supply module unchanged, and adjust the opening degree of at least one other air valve that is opened; for example, keep the opening rate of the air valve in the ventilation system = 50% and the motor revolution number of the air supply module unchanged, and adjust the opening degree of the air valve in space 1 from 30° to 60°;

[0146] Step 504: End.

[0147] Therefore, by controlling the opening of the air valves in the space respectively, the ventilation volume of different indoor spaces or different areas of the indoor space can be adjusted independently; and when the opening of at least one air valve is adjusted, the air volume of the air supply module is adjusted according to the opening rate of the air valve in the ventilation system. While adjusting the ventilation volume of part of the indoor space or part of the area, the change of the ventilation volume of other indoor spaces or other areas can be avoided, thereby avoiding the increase of noise caused by ventilation in other indoor spaces or other areas, avoiding the impact on other users, thereby ensuring the user's comfort and usage experience.

[0148] Figure 6 is another flow chart of a specific method for implementing step 401 in an embodiment of the present application. For example, Figure 6 The specific process of "adjusting the opening of at least one air valve, keeping the opening of other air valves unchanged according to the opening rate of the air valves in the ventilation system, and adjusting the air volume of the air supply module" is shown.

[0149] like Figure 6 As shown, the method includes:

[0150] Step 601: Start; for example, during the initial operation of the ventilation system, the opening of the air valve of space 1 is 30°, and the opening of the air valve of space 2 is 60°;

[0151] Step 602: adjusting the opening of a damper; for example, adjusting the opening of the damper of space 1 to 60°;

[0152] Step 603: Keep the opening of other air valves unchanged and adjust the air volume of the air supply module; for example, keep the opening of the air valve of space 2 at 60°, and the opening rate of the air valve = 33.3%. For example, according to the correction coefficient corresponding to "Model 1" in Table 1, adjust the correction coefficient in the ventilation system from 0.8 to 0.7;

[0153] Step 604: End.

[0154] Therefore, by controlling the opening of the air valves in the space respectively, the ventilation volume of different indoor spaces or different areas of the indoor space can be adjusted independently; and when the opening of at least one air valve is adjusted, the air volume of the air supply module is adjusted according to the opening rate of the air valve in the ventilation system. While adjusting the ventilation volume of part of the indoor space or part of the area, the change of the ventilation volume of other indoor spaces or other areas can be avoided, thereby avoiding the increase of noise caused by ventilation in other indoor spaces or other areas, avoiding the impact on other users, thereby ensuring the user's comfort and usage experience.

[0155] According to the above embodiment, by providing multiple air valves in multiple air ducts connected to the air supply module or at the air outlets of multiple air ducts, the ventilation volume of different indoor spaces or different areas of indoor spaces can be independently adjusted; and when the opening degree of at least one air valve is adjusted, the air volume of the air supply module and at least one of the opening degrees of other air valves are adjusted according to the opening rate of the air valve in the ventilation system. While adjusting the ventilation volume of part of the indoor space or part of the area, the change of the ventilation volume of other indoor spaces or other areas can be avoided, thereby avoiding the increase of noise caused by ventilation of other indoor spaces or other areas, avoiding the impact on other users, thereby ensuring the user's comfort and usage experience.
