Description

Technical Field

[0001] This utility model relates to the field of building greening technology, and in particular to a novel building vertical greening device and greening system. Background Technology

[0002] Currently, vertical greening technology for building facades is widely used to improve the urban built environment. Existing technologies typically employ modular vertical greening systems, mainly consisting of a fixed frame, planting units, and a basic irrigation system. However, these existing technologies have several shortcomings: limited environmental control capabilities, relying primarily on the natural transpiration of plants to regulate ambient temperature, which has limitations such as the cooling effect being significantly affected by plant species, growth status, and planting density; plants are susceptible to high-temperature damage under strong solar radiation, resulting in a significant decrease in cooling effectiveness; and the lack of active cooling mechanisms makes it impossible to meet the temperature control needs of building facades under extreme weather conditions.

[0075] The working surface of this utility model can typically be a plane or a curved surface, and can be inclined or horizontal. For ease of explanation, the embodiment of this utility model is placed on a horizontal surface and used on a horizontal surface, thereby defining "height" and "vertical".

[0076] Example 1

[0077] This embodiment discloses a novel building vertical greening device (hereinafter referred to as the greening device), such as Figures 1-11 As shown, it includes:

[0078] External wall support component 1 is detachably installed on the exterior facade of the building;

[0079] Greening component 2 is disposed on the side of the exterior wall support component 1 away from the building facade;

[0080] The water circulation mechanism includes an irrigation component 3 and a spray component 4 located within the external wall support assembly 1. The irrigation component 3 is configured to cooperate with the greening component 2. The spray component 4 extends at least partially from within the external wall support assembly 1 and is located outside the greening component 2.

[0081] The external wall support component 1 is shared by multiple sets of greening components 2 to save materials.

[0082] The external wall support component 1 is preferably installed in areas with high solar radiation intensity, such as the east, south, and west facades of the building, especially at the main entrances and exits of the building.

[0083] According to one embodiment of the present invention, the external wall support assembly 1 includes a support frame 11 and a fixing plate 12. The fixing plate 12 is located inside the support frame 11. The support frame 11 is configured to be detachably connected to at least the exterior facade of the building. The greening assembly 2 is installed on the outside of the fixing plate 12 (i.e., on the side away from the exterior facade of the building).

[0084] The support frame 11 is configured to hold the fixed panel 12 a certain distance away from the building (this distance is called the first distance, i.e., the distance between the fixed panel and the building facade is the first distance), so that a ventilation space is formed between the fixed panel 12 and the building facade. On the one hand, this is not only conducive to the growth of plants planted in the greening components, but also makes it convenient for residents to enjoy the greenery outside their windows. On the other hand, it can minimize damage to the original appearance of the building facade. After the greening device is removed, there is no need to do extra facade restoration work, which is not only time-saving and labor-saving, but also energy-saving and environmentally friendly.

[0085] Preferably, the initial distance is 10-15cm, which ensures both sufficient ventilation and isolation while maintaining the stability of the greening device on the building. Of course, in practical applications, an appropriate initial distance can be set according to the type of plant, building type, regional climate, and other characteristics, and is not limited to 10-15cm.

[0086] Specifically, the support frame 11 includes at least one set of relatively parallel frame strips 111, and each set of frame strips includes two frame strips, respectively disposed on opposite sides of the fixed assembly plate 12. Preferably, the support frame 11 includes two frame strips 111 arranged vertically in parallel. The thickness of the frame strip 111 is equal to the first distance, that is, the thickness of the frame strip 111 is preferably 10~15cm.

[0087] The inner end of the frame strip 111 is detachably connected to the exterior facade of the building. In this embodiment, the frame strip is detachably fixed to the exterior wall surface (i.e., the exterior facade of the building) by expansion bolts. In practical applications, the two can also be connected by other detachable connection methods, such as snap-fit ​​or fastening.

[0088] The outer end of the frame strip 111 is connected to the fixed assembly plate 12. The two can be connected by non-removable methods such as welding or integral molding, or they can be connected by detachable methods. The former connection method is more stable, while the latter connection method is more flexible, convenient and easy to maintain and replace later. In practical applications, the connection method can be selected according to the requirements.

[0089] In this embodiment, any cross-section of the frame strip 111 is an inverted "I" shape, and the cross-section is a surface perpendicular to its extension direction. Specifically, the frame strip 111 includes a front plate and a rear plate arranged relatively parallel to each other, and a connecting plate disposed between the front plate and the rear plate. The connecting plate is perpendicularly connected to the front plate and the rear plate respectively, and is located at the center of the front plate and the rear plate. Preferably, the frame strip 111 is a one-piece formed steel material. The front plate is connected to the fixed assembly plate 12, and the rear plate is detachably connected to the building facade. When the rear plate is connected to the building facade by expansion bolts, the rear plate has through holes that cooperate with the expansion bolts.

[0090] To improve the ventilation effect of the ventilation space, the frame 111 is provided with at least one through-hole 101. Specifically, the vent 101 is set on the connecting plate of the frame 111. Preferably, the sum of the lengths (lengths in the extension direction of the frame 111) of all vents 101 is s, the length of the frame 111 is L, 1 / 2≤s≤2 / 3, so as to ensure both ventilation effect and structural strength of the frame 111.

[0091] Preferably, the ventilation openings 101 of all frame strips 111 are aligned to ensure smooth vertical ventilation.

[0092] The fixing plate 12 includes a base fixing plate 121, a first functional plate 122, and a second functional plate 123 stacked sequentially from the inside out. The base fixing plate 121 is connected to the support frame 11. The first functional plate 122 is attached to and connected to the base fixing plate 121, and the second functional plate 123 is attached to and connected to the first functional plate 122. Preferably, the base fixing plate 121, the first functional plate 122, and the second functional plate 123 are connected together by screws, bolts, or other fasteners, and at least some of the fasteners are connected to the support frame.

[0093] The base fixing plate 121 is connected to the frame strip 11. In this embodiment, one frame strip 11 is connected to the upper end of the base fixing plate, and the other frame strip is connected to the lower end of the base fixing plate. The base fixing plate 121 is made of engineering plastic or aluminum.

[0094] Ventilation holes 102 are evenly distributed on the base fixing plate 121, and the ventilation holes penetrate the inner and outer sides of the base fixing plate to improve the air permeability of the fixing plate. The diameter and density of the ventilation holes 102 can be set according to requirements. Preferably, the total area of ​​all ventilation holes accounts for 1 / 3 to 3 / 5 of the area of ​​the base fixing plate, so as to ensure the mechanical strength of the base fixing plate while having good air permeability.

[0095] The first functional plate 122 and the second functional plate 123 are made of materials with good air and water permeability. They can be made of the same material or different materials; preferably, they are made of the same material to improve their bonding effect. In this embodiment, the first functional plate 122 and the second functional plate 123 are coconut fiber boards, which have advantages such as excellent air and water permeability, strong support, high durability, antibacterial and insect-proof properties, environmental friendliness, and affordability.

[0096] The thickness of the first functional plate 122 and the second functional plate 123 is preferably 2 cm.

[0097] The pipes of the irrigation assembly 3 and the spray assembly 4 are embedded in the first functional plate 122 and / or the second functional plate 123. That is, the pipes can be set separately in the first functional plate, or separately in the second functional plate, or the first and second functional plates can jointly limit the assembly space of the pipes. In this embodiment, the pipes are set separately on the first functional plate for easy assembly.

[0098] To improve the stability of the external wall support assembly 1, a frame (not shown in the figure) is provided on the outside of the fixing plate 12. The frame surrounds the side of the fixing plate 12 and is connected to the support frame 11 to further strengthen the connection between the fixing plate 12 and the support frame 11. The frame is made of engineering plastic or aluminum, preferably the same material as the base fixing plate.

[0099] The second functional plate 123 is provided with a communication port (not shown in the figure) that cooperates with the planting trough 21 of the greening component 2. The communication port is connected to the assembly space of the pipe of the irrigation component 3 on the first functional plate 122, so as to introduce the liquid in the irrigation component 3 into the planting trough for plant growth. The second functional plate 123 is also provided with a perforation (not shown in the figure) for the spray component 4 to pass through.

[0100] In this embodiment, the base fixing plate 121, the second functional plate 122, and the second functional plate 123 are rectangles of the same shape and size, for example, with dimensions of 60cm × 60cm. In practical applications, the shape and size of the base fixing plate 121, the second functional plate 122, and the second functional plate 123 are designed according to the building type, greening requirements, etc.

[0101] Preferably, the length of the frame strip 111 is greater than the width of the fixing panel 12 (the maximum length in the extension direction of the frame strip). This improves the stability of the fixing panel 12 on the frame strip 111 and also enhances the stability of the exterior wall support assembly 1 on the building facade. Furthermore, the width of the fixing panel ≤ the length of the frame strip ≤ 1.5 * the width of the fixing panel, to ensure both stability and the green area of ​​the building.

[0102] Preferably, the back of the external wall support assembly 1 (the side closest to the building facade) is further provided with multiple horizontally arranged guide ramps 13. The guide ramps 13 are connected to the back of the base fixing plate 121 and extend horizontally from one side of the base fixing plate 121 to the other side. The guide ramps 13 are inclined towards the base fixing plate 121, that is, the lower end of the guide ramps 13 is connected to the base fixing plate 121, and the upper end of the guide ramps 13 extends towards the building facade. The angle between the guide ramps 13 and the base fixing plate 121 is α, preferably 30°≤α≤60°, and in this embodiment, α=45°. The width of the guide ramps 13 (its length from top to bottom) is 2~3cm.

[0103] Preferably, the guide ramps 13 are evenly spaced on the back of the base fixing plate 121. In this embodiment, there are six guide ramps 13.

[0104] To improve the stability of the guide plate 13, the guide plate 13 is welded to the base fixing plate 121, or the guide plate 13 and the base fixing plate 121 are integrally formed.

[0105] By setting up guide ramps, the air velocity in the ventilation space can be increased. The principle is the Venturi effect: when fluid passes through a narrow channel, the flow velocity increases and the pressure decreases, thereby reducing the surface temperature of the building's exterior walls and effectively reducing building energy consumption.

[0106] In addition, the thickness of the ventilation space (i.e., the distance from the base fixing plate to the exposed surface of the building) and the number of guide ramps change in tandem with the plant coverage rate. The higher the plant coverage rate, the greater the thickness of the ventilation space and the greater the density of the guide ramps, so as to enhance the ventilation effect.

[0107] According to one embodiment of this utility model, the greening component 2 is disposed on the outside of the fixed assembly plate 12, that is, the greening component 2 is attached to and connected to the second functional plate 123. Preferably, the greening component 2, the second functional plate 123, the first functional plate 122 and the base fixing plate 121 are connected together by screws, bolts or other connecting parts, and at least some of the connecting parts are connected to the support frame.

[0108] The greening component 2 is provided with multiple planting troughs 21, the opening of which is vertically upward, and the planting troughs 21 are connected to the communication opening on the second functional plate 123. The depth a of the planting trough is 12~18cm (preferably 15cm), and the width b of the opening is 18~23cm (preferably 20cm).

[0109] Multiple planting troughs 21 are connected by planting connecting plates 22 to form a greening component 2. That is, multiple planting troughs 21 are set on the planting connecting plates 22, and the planting connecting plates 22 have connecting holes (not shown in the figure) that connect the planting troughs to the connecting holes. The arrangement of the planting troughs 21 on the planting connecting plates 22 can be set according to actual needs. In this embodiment, the planting troughs 21 are arranged in multiple horizontal rows, with multiple planting troughs in each row, and the planting troughs in adjacent rows are staggered.

[0110] The planting trough 21 is shaped like a semi-inverted "bell" or a "pocket" shape that is wider at the top and narrower at the bottom. That is, the planting trough 21 gradually tightens from the opening downwards, and the outer side wall of the planting trough protrudes outwards to form a streamlined protruding side wall. The outer side wall of the planting trough 21, except for the upper edge, is connected to the planting connecting plate 22.

[0111] To improve the air permeability of the greening components, the planting connecting plate 22 is provided with ventilation holes 201. The ventilation holes 201 are evenly distributed on the planting connecting plate 22. The diameter of the ventilation holes 201 is 3~8mm (preferably 5mm), and the spacing between adjacent holes is 10~20mm (preferably 15mm).

[0112] To improve planting effectiveness, the outer wall of the greening component 2 is coated with a phase change layer (not shown in the figure), meaning that both the outer walls of the planting trough 21 and the planting connecting plate 22 are coated with a phase change layer. The phase change layer uses a phase change material to enhance the heat storage and release effect of the greening component, ensuring the surface temperature of the greening component remains relatively stable and preventing plant burns. For example, the phase change material can be paraffin wax or carnauba wax.

[0113] Preferably, the greening component 2 is an integrally formed perforated aluminum alloy plate. The manufacturing process is as follows: after punching holes in the aluminum alloy plate, a protruding arc-shaped part is formed outward from the punched hole to form a planting trough.

[0114] The planting trough 21 contains a planting substrate, and plants are planted within the planting substrate. The thickness of the planting substrate is less than the depth of the planting trough 21, meaning the planting substrate cannot overflow the planting trough 21. Preferably, the thickness of the planting substrate is 8-10 cm.

[0115] The planting substrate includes peat moss, perlite, vermiculite, and coconut coir. The ratio of these four components can be adjusted according to the plants to be planted, and other substances can be added to improve the compatibility between the planting substrate and the plants. For example, a planting substrate made of peat moss, perlite, vermiculite, and coconut coir in a ratio of 4:3:2:1 is suitable for most green plants.

[0116] The water supply pipes of the irrigation component 3 and the spray component 4 are independent of each other. That is, the irrigation component 3 includes an irrigation pipe 31, and the spray component 4 includes a spray pipe (not shown in the figure) and a nozzle 41. The irrigation pipe 31 and the spray pipe are independent of each other.

[0117] The irrigation pipe 31 is configured to irrigate each planting trough 21 with liquid, in accordance with the distribution of the planting troughs of the greening component 2. The irrigation pipe 31 is provided with drip irrigation holes (not shown in the figure) that mate with the planting troughs, and each planting trough has at least one corresponding drip irrigation hole.

[0118] When the plants planted on the greening component 2 are of the same type, the irrigation pipe 31 connects all the drip irrigation holes in series. An irrigation valve is provided on the irrigation pipe 31 to control the opening and closing of the entire irrigation pipe and the flow rate of the liquid in the pipe. That is, the irrigation valve can control whether there is liquid in each drip irrigation hole and the flow rate of the liquid.

[0119] When multiple plants are planted on the greening component 2, the irrigation pipe 31 is equipped with multiple parallel irrigation branches, each responsible for irrigating one type of plant. The drip irrigation holes on each branch can be configured according to the type of plant. Each irrigation branch is equipped with an independent irrigation valve to independently control the opening and closing of the irrigation branch and the liquid flow rate within the branch. In other words, the irrigation valve can independently control whether there is liquid in each drip irrigation hole on the branch and the flow rate of the liquid.

[0120] Of course, if the water requirements of various plants on the greening component 2 are similar, the setting of the irrigation pipe 31 for the same type of plant can be referenced to simplify the control procedure.

[0121] The irrigation sequence of the planting trough in the greening component 2 is from top to bottom.

[0122] This embodiment provides an irrigation pipe 31 that connects all drip irrigation holes in series. It is a tubular pipe, resembling a winding S-shaped track, comprising a riser 311, multiple horizontal pipes 312 arranged parallel to each other and connected end-to-end, and a bend 313. The riser 311 extends vertically upward from the lower end of the fixed assembly plate 2, connecting to the uppermost horizontal pipe 312. The horizontal pipes 312 are connected end-to-end via curved bends 313. The lowermost horizontal pipe 312 extends vertically downward from its end, exiting the fixed assembly plate 2. Preferably, the upward extension of the riser 311 and the extension of the lowermost horizontal pipe 312 are located at the same corner of the fixed assembly plate 2.

[0123] In some embodiments, to improve the irrigation effect of the irrigation component on the plants, the drip irrigation hole is provided with a capillary tube 32, which extends from the drip irrigation hole into the planting trough 21 to accelerate the rapid guidance of liquid in the irrigation component into the planting trough 21. The end of the capillary tube 32 can be located above or inside the planting substrate.

[0124] The arrangement of the spray pipes in the spray assembly 4 is independent of the planting trough layout. The spray pipes can be installed independently within the first functional plate, independently within the second functional plate, or within the assembly cavity jointly defined by the first and second functional plates. A suitable arrangement can be selected based on the actual situation. In this embodiment, the spray pipes are installed within the second functional plate.

[0125] The nozzle 41 is mounted on the planting plate 22 of the greening component 2 via a fixed bracket 42. The tail end of the spray pipe passes through the fixed assembly plate 12 and the planting plate 22 in sequence and is connected to the nozzle 41 on the fixed bracket 42 to provide the nozzle 41 with liquid to form a spray. The fixed assembly plate 12 and the planting plate 22 are provided with perforations for the spray pipe to pass through.

[0126] For example, the fixing bracket 42 is an "L" shaped plate. Specifically, the fixing bracket 42 includes a long plate and a short plate connected vertically. One end of the long plate is vertically connected to the planting plate (the two can be detachably connected or welded). The other end of the long plate is connected to the short plate. The short plate is provided with fixing holes for fixing the nozzle 41. Part of the nozzle 41 passes through the fixing holes and is fixed on the fixing bracket 42.

[0127] To ensure that the mist sprayed from the nozzle 41 covers the greening component as much as possible and facilitates outward diffusion, the spraying component 41 is equipped with multiple nozzles. Most of the nozzles are arranged to cover the largest possible area and are positioned close to the building's windows. This allows the mist to spray into the external space, forming a fog layer around the window, reducing solar radiation penetration and thus lowering indoor temperature and ultraviolet radiation. For example, when there are two nozzles, they are positioned on the upper part of the greening component near the sides.

[0128] In this embodiment, both the spray pipe and the irrigation pipe are made of 304 stainless steel with a diameter of 10mm. The nozzle is a micro-mist nozzle with a nozzle diameter of 0.6~1mm and a working pressure of 2~6MPa.

[0129] The spray assembly 4 is equipped with a control valve for controlling the spray flow rate, so as to realize intelligent control of whether to spray and the spray flow rate.

[0130] The water circulation mechanism also includes a storage tank, a water pump, a filter, and a collection tank 5. The storage tank is equipped with an outlet pipe and a return pipe. One end of the outlet pipe is connected to the storage tank, and the other end is connected to the beginning of the spray pipe and the beginning of the irrigation pipe, respectively. The water pump is located in the path of the outlet pipe to transport the liquid in the storage tank to the spray pipe and the irrigation pipe. One end of the return pipe is connected to the end of the irrigation pipe and the collection tank 5, respectively. The filter is located in the path of the return pipe to filter and recycle the liquid flowing back into the storage tank.

[0131] The water collection trough 5 is located at the bottom of the external wall support component 1 and is configured to at least support the bottom of the greening component 2 and the fixed assembly 12, that is, the downward projection of the greening component 2 and the fixed assembly 12 can fall into the water collection trough 5, so as to collect and recover liquids that may seep out of the greening component 2, liquids that may leak from the irrigation pipes and spray pipes in the fixed assembly 12, and rainfall.

[0132] To facilitate rapid recovery of liquid in the water collection tank 5, its bottom is inclined.

[0133] In this embodiment, the water collection trough 5 is a rectangular trough, with the outer side of the rear wall of the trough connected to the frame strip 111 and the inner side of the rear wall of the trough connected to the base fixing plate 121. The connection between the water collection trough 5 and the frame strip and the base fixing plate can be a detachable connection or a non-detachable welding connection.

[0134] The filter preferably adopts a two-stage filtration structure to ensure filtration effectiveness.

[0135] It should be noted that multiple sets of external wall support components and greening components are installed on the building facade, and these multiple sets of external wall support components and greening components can share the same liquid storage tank, water pump, and filter.

[0136] Optionally, a three-way valve is used at the inlet of the irrigation pipe to connect the building's greywater pipe and the storage tank. When the water volume in the storage tank is insufficient to complete irrigation, the greywater pipe is automatically connected for irrigation.

[0137] Optionally, the spray pipe is connected to a tap water pipe and an alcohol additive storage device via a mixing valve. The tap water and alcohol additive are mixed evenly in the mixing valve before being sprayed out by the spray device. Because the alcohol additive is volatile, it can improve the cooling performance of the spray.

[0138] The water pump is electrically connected to the control component, meaning that the water pump is controlled through the control component.

[0139] To enable more intelligent control of the greening device, the liquid storage tank is equipped with a liquid level sensor and a water quality sensor.

[0140] Example 2

[0141] This embodiment discloses a novel building vertical greening system (hereinafter referred to as the greening system), including:

[0142] The novel building vertical greening device provided in Example 1;

[0143] The control component is configured to control the water circulation mechanism based at least on the growth conditions and environmental conditions of the plants planted in the greening component 2.

[0144] The irrigation valve of the greening device is a solenoid valve, which is electrically connected to the control component. In other words, the irrigation valve is controlled by the control component to achieve intelligent control of plant irrigation.

[0145] The control valve of the spray assembly 4 is electrically connected to the control assembly, that is, the control valve is controlled by the control assembly to achieve intelligent control of whether to spray and the spray flow rate.

[0146] The water pump of the greening device is electrically connected to the control component, that is, the water pump is controlled through the control component.

[0147] The liquid level sensor and water quality sensor of the greening device are electrically connected to the control component. The liquid level sensor transmits the collected liquid position signal (i.e., liquid level signal) from the storage tank to the control component in real time. The control component determines the liquid storage status in the storage tank based on the received liquid level signal. When the real-time liquid level in the storage tank is lower than a preset level, the control component is configured to issue an alarm or a replenishment command to promptly replenish the liquid in the storage tank. Similarly, the water quality sensor transmits the collected water quality signal from the storage tank to the control component in real time. The control component determines the water quality status in the tank based on the received water quality signal and then determines whether a new filter needs to be replaced. When the real-time water quality in the storage tank is lower than a preset water quality level, the control component is configured to issue an alarm or a filter replacement command to promptly replace the filter and ensure the water quality in the storage tank.

[0148] The greening system also includes a variety of environmental sensors, which are electrically connected to the control component. The control component is configured to at least accept signals detected by the environmental sensors. For example, the environmental sensors include temperature sensors, humidity sensors, solar radiation sensors, moisture sensors, etc., to monitor the external environmental parameters of the greening system and the substrate environmental parameters in the planting trough.

[0149] The moisture sensors are located inside the planting troughs, with at least one trough for each type of plant equipped with a moisture sensor to detect the moisture content of the planting substrate. Specifically, the moisture sensors transmit the collected moisture content signal from the planting substrate to the control component in real time, and the control component determines the moisture content of the planting substrate based on the received signal.

[0150] The temperature sensor, humidity sensor, and solar radiation sensor are installed on the planting board, preferably near its four corners. These sensors detect the temperature, humidity, and solar radiation levels of the external environment of the greening system. Specifically, they transmit the collected signals to the control component in real time, allowing the control component to determine the temperature, humidity, and solar radiation levels of the external environment based on the received signals.

[0151] The control component, based on the determined external environmental parameters and the substrate environmental parameters within the planting trough, controls the irrigation process of the irrigation component and the spraying process of the spraying component, thereby achieving intelligent irrigation of plants and temperature and humidity regulation of the environment. Specifically, irrigation and spraying conditions can be preset; when one or more monitored parameters reach the preset conditions, irrigation and / or spraying will proceed.

[0152] The irrigation and spraying conditions are related to factors such as the type of plants being planted and the geographical location of the building.

[0153] For example, for greening systems on building facades in Beijing, spraying is automatically activated when the temperature is above 28°C, the relative humidity is below 60%, and the area is exposed to direct sunlight; irrigation is automatically activated when the substrate layer humidity is below 50%.

[0154] It should be noted that all of the above sensors can send signals in real time or at preset intervals, depending on the actual requirements.

[0155] The control component also includes an alarm unit and a remote control unit. The alarm unit is configured to trigger an alarm signal corresponding to the fault when any electrical component of the greening system malfunctions, ensuring timely maintenance by staff. The remote control unit is configured to remotely control the control component via a remote control device (such as a smart terminal, remote control, etc.), thereby controlling the operation of the greening system.

[0156] This invention, through the synergistic effect of the spray component and plant greening, can significantly improve the cooling effect of building facades and ensure the growth environment of plants under extreme weather conditions.

[0157] This invention achieves precise irrigation and spray control through multi-parameter environmental monitoring, thereby improving water resource utilization efficiency.

[0158] This invention organically combines vertical greening, environmental control, and intelligent monitoring functions to achieve coordinated system operation and intelligent management. It also provides a highly adaptable and easy-to-maintain building vertical greening solution, effectively reducing system maintenance costs and extending service life.

[0159] This utility model is a highly efficient building exterior wall cooling system. The greening components form a ventilation space of a certain thickness between the greening components and the building exterior wall, which can effectively eliminate direct sunlight on the exterior wall.

[0160] This invention can reduce the ambient air temperature by 1-15°C and increase the relative humidity by 5.3%-29.3%, significantly improving the outdoor thermal environment. When this invention is installed around a window, the mist droplets from the spray control device form a fog layer on the glass surface, which can reduce the solar radiation transmittance by 9%-12.3%, effectively lowering the indoor temperature.

[0161] This invention enables intelligent management and efficient utilization of water resources, and also incorporates a circulating water collection system to achieve the recycling of irrigation water.

[0162] This invention can be appropriately adjusted according to the climate characteristics of the installation site and the water requirements of the planted plants. The system supports dynamic setting of preset parameters and can be optimized according to actual conditions through the control interface. The multi-parameter intelligent control module has multiple settings, which can be dynamically set according to the climate conditions of different climate zones and plant species. It can also be remotely controlled through an app or mini-program.

[0163] This invention boasts high integration and reliability. Employing a modular landscape design, it integrates environmental monitoring, mist control, and plant irrigation functions. The innovative use of impulse boards and phase change materials ensures long-term stable operation in outdoor environments. The coordinated operation of all components contributes to high overall system stability. The standardized modular design facilitates rapid assembly, and the detachable structure allows for convenient plant renewal and maintenance. Applicable to building facades facing different directions, it offers excellent versatility and expandability. Furthermore, this invention enables intelligent management, including fault diagnosis and anomaly alarm mechanisms, supporting real-time monitoring of system operation.

The program can be stored on a computer-readable storage medium or integrated into a mobile app (such as a WeChat mini-program).

[0165] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
