Description

Technical Field

[0001] This invention relates to a technology for assisting in regulating indoor air circulation in high-rise buildings, belonging to the field of high-rise building ventilation. Background Technology

[0002] Improving the natural ventilation in high-rise residential buildings is about creating a comfortable and healthy living environment and enhancing the quality of life in these homes.

[0003] Introducing fresh outdoor air into the building while expelling stale indoor air improves ventilation in existing high-rise tower residential buildings, thus creating a healthy indoor environment. Air conditioning and other similar equipment can cause secondary air pollution, which is detrimental to creating a healthy indoor environment.

[0004] However, many high-rise public buildings lack effective natural ventilation measures. Currently, ventilation in high-rise buildings relies either on central air conditioning or solely on individual windows. Central air conditioning is not only energy-intensive but also leads to unsanitary air due to the difficulty of cleaning it. Relying solely on individual windows is ineffective; strong winds can cause discomfort or disarray, and people sitting in "dead corners" far from windows may find the airflow insufficient. Therefore, direct airflow from windows is uneven and ineffective.

[0005] It is evident that the lack of effective natural ventilation in high-rise buildings leads to a low health index in the living environment and wastes energy. Summary of the Invention

[0006] In view of the problems existing in the natural ventilation of high-rise buildings, the present invention provides an external window air guide component and adjustment method for adjusting the indoor air quality of high-rise buildings.

[0007] The wind-guiding component for regulating indoor air quality in high-rise buildings as described in this invention includes a top plate 1, a bottom plate 2, and a wind deflector 3.

[0008] The top plate 1 and the bottom plate 2 are set parallel to each other on the wall above and below the exterior window; both the top plate 1 and the bottom plate 2 are triangular plate structures, the long straight side of the triangular plate is fixed to the wall where the exterior window is located, the short straight side of the triangular plate is perpendicular to the wall where the exterior window is located, and an arc-shaped track 4 is set on the hypotenuse of the triangular plate, the arc-shaped track 4 being close to the short straight side of the triangular plate.

[0009] The wind deflector 3 includes a square frame 3-1 and louvered fans 3-2. Multiple louvered fans 3-2 are arranged side by side inside the square frame 3-1. One vertical side of the square frame 3-1 is hinged to the right-angle vertex of the top plate 1 and the bottom plate 2. The other vertical side of the square frame 3-1 slides along two arc-shaped tracks 4 to adjust the angle between the windward surface of the outer window wind guide component and the wind direction.

[0010] Preferably, the central angle β of the arc track is between 30° and 45°.

[0011] Preferably, the top plate 1 adopts a frame structure, and the bottom plate 2 is composed of a frame and a shelf of the same shape on it.

[0012] Preferably, the frame is made of aluminum-plastic pipe and the shelf is made of dry-hanging aluminum plate.

[0013] Preferably, the common endpoint of the long straight side and the inclined side of the top plate 1 is supported by a column with respect to the common endpoint of the long straight side and the inclined side of the bottom plate 2.

[0014] This invention also provides another technical solution: a system for regulating indoor air quality in high-rise buildings, based on the aforementioned window air guide component for regulating indoor air quality in high-rise buildings. The system includes an indoor sensor, an outdoor sensor, a terminal controller, and an actuator. The regulation process includes:

[0015] S1. Data acquisition steps: Indoor sensors detect indoor air quality and acquire indoor temperature, indoor average wind speed, and indoor air uniformity; outdoor sensors detect outdoor wind speed and wind direction.

[0016] S2. Terminal Data Judgment Steps: The terminal controller determines whether the following two conditions are met simultaneously based on the data collected by the sensors:

[0017] Condition 1: The average indoor wind speed v ≤ 0.01 m / s or v ≥ 0.3 m / s

[0018] Condition 2: Indoor air uniformity P ≤ 0.6

[0019] If both of the above conditions are met, proceed to step S3; otherwise, return to step S2.

[0020] S3. The actuator starts, adjusting the air guide components of the outer window;

[0021] The adjustable wind guide components for the exterior window include a wind deflector 3 that slides along two arc-shaped tracks 4 to adjust the angle between the windward side of the wind guide component and the wind direction, and a louvered fan that rotates along its own central axis to change the air intake volume.

[0022] Preferably, the indoor air uniformity P is calculated using the following formula:

[0023]

[0024] In the formula, v max v represents the maximum indoor wind speed. min This represents the minimum indoor wind speed.

[0025] Preferably, after executing step S3, the process returns to executing step S2.

[0026] Preferably, the control system further includes a cloud controller, and the remote control process using the cloud controller includes:

[0027] The data obtained in step S1 is uploaded to the cloud controller. The results of cloud data processing are sent to the client. The client user sets the ventilation mode and starts the actuator according to the ventilation mode to adjust the air guide component of the outer window.

[0028] Preferably, the ventilation modes include: a mode for adjusting the angle α between the wind deflector and the facade and a mode for adjusting the opening and closing angle of the louvers. The adjustment range of the angle α between the wind deflector and the facade is 0 to β, and the adjustment range of the opening and closing angle of the louvers is 0 to 90°.

[0029] The beneficial effects of this invention are:

[0030] This invention improves indoor air quality by controlling the average indoor wind speed and air uniformity. The device utilizes natural wind effectively, saving energy. Compared to existing patents that adjust indoor airflow by changing the angle of louvers, this invention focuses more on the renovation of existing buildings, making it easier to install on older structures.

[0031] When folded, it is easy to store and transport; when needed, it can be quickly installed in the windows of existing high-rise buildings. This invention has the advantages of small size, high folding efficiency, simple engineering implementation, low cost, and energy saving.

[0032] This invention addresses the issue of natural ventilation in high-rise buildings during winter in cold regions, and is of great significance for home health in the post-pandemic era. Attached Figure Description

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0045] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0046] Specific Implementation Method 1: The following is combined with... Figures 1 to 3 This embodiment describes an external window air guide component for regulating indoor air quality in high-rise buildings, comprising a top plate 1, a bottom plate 2, and a windbreak plate 3.

[0047] The top plate 1 and the bottom plate 2 are set parallel to each other on the wall above and below the exterior window; both the top plate 1 and the bottom plate 2 are triangular plate structures, the long straight side of the triangular plate is fixed to the wall where the exterior window is located, the short straight side of the triangular plate is perpendicular to the wall where the exterior window is located, and an arc-shaped track 4 is set on the hypotenuse of the triangular plate, the arc-shaped track 4 being close to the short straight side of the triangular plate.

[0048] The wind deflector 3 includes a square frame 3-1 and louvered fans 3-2. Multiple louvered fans 3-2 are arranged side by side inside the square frame 3-1. One vertical side of the square frame 3-1 is hinged to the right-angle vertex of the top plate 1 and the bottom plate 2. The other vertical side of the square frame 3-1 slides along two arc-shaped tracks 4 to adjust the angle between the windward surface of the outer window wind guide component and the wind direction.

[0049] See Figure 1 The high-rise building room 5 is equipped with an exterior window 6. An exterior window wind guide component is installed outside the exterior window 6. The wind baffle 3 of the exterior window wind guide component is installed on the opening side of the exterior window 6 to better control the air intake.

[0050] The central angle β of the curved track is between 30° and 75°. Generally, around 45° is chosen.

[0051] The top plate 1 adopts a frame structure, and the bottom plate 2 is composed of a frame and a shelf of the same shape on it.

[0052] The frame is made of aluminum-plastic pipe, and the shelf is made of dry-hanging aluminum plate.

[0053] The common endpoints of the long straight edge and the inclined edge of the top plate 1 and the common endpoints of the long straight edge and the inclined edge of the bottom plate 2 are supported by columns. This arrangement is to increase mechanical strength and make the air guide components of the exterior window more stable.

[0054] Specific Implementation Method Two: The following is combined with... Figures 1 to 10 This embodiment describes a high-rise building indoor air quality regulation system, which is based on the external window air guide component for regulating indoor air quality in high-rise buildings described in Embodiment 1. The regulation system includes an indoor sensor, an outdoor sensor, a terminal controller, a cloud controller, and an actuator. The regulation system consists of two parts: the first part is that the terminal controller adaptively adjusts based on the collected real-time data, and the second part is that the user controls it using a smart terminal.

[0055] The first part of the adjustment process includes:

[0056] S1. Data acquisition steps: Indoor sensors detect indoor air quality and acquire indoor temperature, indoor average wind speed, and indoor air uniformity; outdoor sensors detect outdoor wind speed and wind direction.

[0057] S2. Terminal Data Judgment Steps: The terminal controller determines whether the following two conditions are met simultaneously based on the data collected by the sensors:

[0058] Condition 1: The average indoor wind speed v ≤ 0.01 m / s or v ≥ 0.3 m / s

[0059] Condition 2: Indoor air uniformity P ≤ 0.6. Indoor air uniformity P is calculated using the following formula:

[0060]

[0061] In the formula, v max v represents the maximum indoor wind speed. min This represents the minimum indoor wind speed.

[0062] If both of the above conditions are met, proceed to step S3; otherwise, return to step S2.

[0063] S3. The actuator starts, adjusting the air guide components of the outer window;

[0064] The adjustable wind guide components for the exterior window include a wind deflector 3 that slides along two arc-shaped tracks 4 to adjust the angle between the windward side of the wind guide component and the wind direction, and a louvered fan that rotates along its own central axis to change the air intake volume.

[0065] See Figure 4 An external window wind guide component is installed on the wall where the external window 6 is located. An angle α is set between the wind deflector 3 and the facade (the left wall of the room in the diagram). By changing α, the angle n between the windward side and the wind direction and the openness m of the windward side are changed, thereby altering the indoor wind speed and air uniformity. A high level of comfort is considered to be achieved when the indoor average wind speed v is between 0.01 and 0.3 m / s and the indoor air uniformity P > 0.6; this is the target of the adjustment system in this embodiment.

[0066] The outdoor sensor can monitor the outdoor wind speed. If the outdoor wind speed is high, the wind deflector 3 can be adjusted to make the air intake channel smaller. If the outdoor wind speed is low, the wind deflector 3 can be adjusted to make the air intake channel larger.

[0067] After executing step S3, return to execute step S2.

[0068] The second part, the remote adjustment process utilizing the cloud controller, includes:

[0069] The data obtained in step S1 is uploaded to the cloud controller. The results of cloud data processing are sent to the client. The client user sets the ventilation mode and starts the actuator according to the ventilation mode to adjust the air guide component of the outer window.

[0070] The ventilation modes include: the wind deflector and facade angle α adjustment mode and the louver opening and closing angle adjustment mode. The adjustment range of the wind deflector and facade angle α is 0 to β, and the adjustment range of the louver opening and closing angle is 0 to 90°.

[0071] When conducting experiments on the morphology of the external window air guide component of this invention, the experimental room was first simplified into a cube with dimensions of 3*3*3m, and the facade components were simplified into protruding wall piers. See Figure [Figure Number] for the state without the device of this invention installed. Figure 7As shown. In establishing the experimental model, we changed the length L of the wall pier windbreak and the angle α between the windbreak and the facade to alter the angle n between the windward side and the wind direction, and the openness m of the windward side. The data processing involved importing different experimental models into the Swell ventilation software for calculation, resulting in a series of wind speed cloud maps. After processing and calculating the maps, we obtained two main factors for determining the quality of the indoor wind environment: the indoor average wind speed v- and the air uniformity P. The closer the air uniformity is to 1, the better. Figure 8 This is a simplified model of a high-rise building test room equipped with the wind-guiding component of the external window of this invention and a wind speed cloud map. The projected length of the wind deflector on the facade is L = 1500 mm, and the angles between the wind deflector and the side wall facade are 0°, 15°, and 30°, respectively. Figure 9 This is a simplified model of a high-rise building test room equipped with the wind-guiding component of the external window of this invention and a wind speed cloud map. The projected length of the wind deflector on the facade is L = 1000 mm, and the angles between the wind deflector and the side wall facade are 0°, 15°, 30°, 45°, 50°, and 60°, respectively. Figure 10 This is a simplified model and wind speed cloud map of a high-rise building test room equipped with the wind-guiding component of the external window of this invention. The projected length of the wind deflector on the facade is L = 500mm, and the angles between the wind deflector and the side wall facade are 0°, 15°, 30°, 45°, 60°, and 75°, respectively.

[0072] According to the longitudinal and transverse comparison of the experimental data, it can be seen that: (1) When the angle α between the wind deflector and the facade remains unchanged, adjusting the length of the wind deflector so that the angle between the windward side and the wind direction is closer to 90° will result in a higher average indoor wind speed. Considering the shape factors, a wind deflector projection length of 1500mm on the facade is optimal. (2) When the projection length of the wind deflector on the facade remains unchanged, changing the angle α between the wind deflector and the facade can affect the size of the air inlet and the size of the indoor air duct (indoor air uniformity). This makes the indoor wind speed adjustable; in summer, the wind deflector can be adjusted to maximize its vertical length to draw air into the room; in winter, the wind deflector can be adjusted to slide inward along the guide rail to reduce the air inlet, reduce the range of the indoor air duct, and improve comfort. The effect is better when the angle between the wind deflector and the side wall facade is between 30° and 45°. Based on the experimental data, this invention discards larger or smaller angles.
