Description

Technical Field

[0001] The present application relates to the technical field of roof insulation modules, and in particular to an ecological planting roof module. Background Art

[0002] The outdoor meteorological conditions in the subtropical climate zone in summer are characterized by long sunshine hours, high solar radiation intensity, high outdoor air temperature and high relative humidity. Roof insulation has important application value for building energy conservation.

[0003] Buildings generally use an insulation layer in the roof structure layer to insulate the building, or a large brick ventilation layer is installed on the original building roof for insulation. This form of insulation solves the basic insulation problem of the roof to a certain extent and meets the requirements of the current roof energy-saving standards. However, there are still some problems: (1) The ecological performance of the building roof is poor, and it has not fundamentally solved the urban ecological environment problems such as the heat island effect caused by the hardened roof. (2) Although the roof insulation performance can meet the basic requirements of the energy-saving standards, it still has disadvantages such as poor thermal comfort and high energy consumption in the top room during actual use. (3) The building roof area accounts for about 80% of the urban area. The increase in hardened roofs has reduced the area of ​​urban green space, causing a sharp decline in the thermal environment of the urban area, and the resulting greenhouse effect and heat island effect seriously threaten the comfort and health of residents. (4) The increase in hardened roofs has increased the drainage rate of rainwater on urban roofs, creating flood discharge pressure on the urban drainage network and forming a hidden danger of urban floods. (5) The reduction in green vegetation area has reduced the city’s carbon reduction effect, causing a continuous adverse impact on the urban area’s thermal environment and the realization of energy conservation and carbon reduction goals.

Obviously, the described embodiments are part of the embodiments of the present application, not all of them. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the embodiments of the present application are within the scope of protection of the embodiments of the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0055] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0056] The applicant has found through research that:

[0057] (I) The general overhead ventilated roof has low heat dissipation capacity and mainly has the following problems:

[0058] (1) The ecological function of the roof is missing.

[0059] (2) The thermal insulation performance is poor and the height of the overhead layer is low, which limits the thermal pressure driving capacity and ventilation volume, affecting the heat dissipation capacity of the ventilation layer.

[0060] (3) The large-scale laying of overhead floors makes the ventilation duct longer, which increases the air resistance along the way, affecting the ventilation speed and heat exchange process.

[0061] (4) The air flow in the overhead channel mainly relies on thermal pressure. When the temperature difference between the outside air and the air in the channel is small, the inlet and outlet air flow is not obvious and the heat dissipation effect is poor.

[0062] (II) Water storage roof:

[0063] The water storage roof can collect rainwater from the roof, and the water storage reflects and absorbs solar radiation heat. The evaporation of water takes away a large amount of vaporization heat, and also accumulates heat and dissipates the heat stored in the water storage layer through radiation heat dissipation at night. The thermal insulation capacity of the water storage roof mainly depends on the local climate characteristics and the evaporation and heat dissipation capacity of the water storage. The more suitable the local climate characteristics are for the evaporation of water storage, the stronger its evaporation and heat dissipation capacity is, and the better the cooling effect of the corresponding water storage roof is, and vice versa. The main problems with water storage roofs are as follows:

[0064] (1) The water storage has a low ability to reflect solar radiation, stores large amounts of heat during the day, and has a high water storage temperature.

[0065] (2) The thermal insulation performance of the water storage roof is positively correlated with the water storage depth. In clear summer weather, the air temperature is high and dry during the day and evening, and the evaporation of stored water is large. As the water storage depth decreases, the thermal insulation performance of the water storage roof decreases.

[0066] (3) In arid areas, there is less rain and municipal water replenishment is needed. Water storage roofs are not economical.

[0067] (4) The thermal insulation performance of water-storage roofs is poor, and the ecological functions such as carbon reduction are weak.

[0068] 3. Greening roof:

[0069] Greening roofs are mainly achieved by planting green plants on the roofs to create roof landscapes and achieve heat insulation. On the one hand, planted roofs can use vegetation shading, thermal resistance of the planting layer and evaporation of soil moisture to reduce the impact of solar radiation on the roof and reduce indoor temperature; on the other hand, large-scale planted roofs can reduce urban surface runoff, extend the life of the roof, improve the thermal and ecological environment of the building roof, beautify the building ecological environment, promote biodiversity between the building and the surrounding area, alleviate the heat island effect, and regulate the urban microclimate. Studies have shown that a city with a greening rate of more than 70% can reduce the city's CO2 content by 80% and weaken the impact of the urban heat island effect.

[0070] The main problems of greening roofs are as follows:

[0071] (1) When the soil layer is thin, its water storage capacity is poor, water evaporates quickly, and is not conducive to vegetation growth; when the vegetation coverage and height are small, solar radiation has a greater impact on soil temperature.

[0072] (2) When the soil is thick, its heat storage capacity is strong, but its heat dissipation capacity is poor at night, resulting in the problem of reverse heat transfer (i.e., the heat of the soil layer at night is higher than the heat of the surrounding air, and the soil layer will transfer heat to the room through the roof).

[0073] (3) Water is needed for the growth of vegetation leaves, and the leaf temperature is relatively high, so spraying and other methods are needed to cool down and replenish water.

[0074] In view of the various problems existing in the above roof insulation, the embodiment of the present application discloses an ecological planting roof module.

[0075] See also Figure 1 as well as Figure 5 An embodiment of an ecological planting roof module provided in the embodiments of the present application includes:

[0076] Roof module unit.

[0077] The roof module unit includes a module body 1 , a planting module 4 , a water storage module 3 and a ventilation module 7 .

[0078] A layout cavity is provided in the module body 1 , and a layout opening communicating with the layout cavity is provided on the top of the module body 1 to facilitate module layout.

[0079] A supporting partition 2 is provided in the arrangement cavity, and the supporting partition 2 divides the arrangement cavity into an upper chamber and a lower chamber; a first connecting hole 11 and a second connecting hole 12 connecting the upper chamber and the lower chamber are provided on the supporting partition 2.

[0080] The planting module 4 is installed in the upper chamber, the ventilation module 7 is installed in the planting module 4, the water storage module 3 is installed in the lower chamber and connected to the first connecting hole 11, and is used to store water flowing out through the first connecting hole 11. A drainage port 13 connected to the lower chamber is also provided on at least one side wall of the module body 1.

[0081] The ecological planting roof module designed in this application has the following beneficial effects:

[0082] 1. Compared with general green roofs, this application is a modular design product, which is convenient for the use of engineering prefabrication and assembled building roofs. This application divides the layout cavity into an upper chamber and a lower chamber. The upper chamber is used for the arrangement of the planting module 4, and the lower chamber is used for the arrangement of the water storage module 3 and also plays an overhead role, realizing the separation of the planting module 4 and the roof structure layer, reducing the influence of the planting module 4 on the heat transfer of the roof. Moreover, the combined application of the ventilation module 7 effectively improves the heat dissipation of the planting module 4, greatly improves the thermal insulation performance of the planting module 4, and realizes the coupling utilization of active ventilation and passive roof greening.

[0083] 2. Compared with general water storage roofs, the water storage module 3 is used to partially store water, replacing the general full water storage mode, which reduces the roof load and eliminates the reverse heat transfer phenomenon of the water storage module 3. The space outside the water storage module 3 in the lower chamber also forms an overhead space, which allows part of the water to be discharged through the drain port 13 while also playing a certain ventilation role, thereby improving the heat dissipation capacity and further improving the thermal insulation effect of the roof.

[0084] 3. Compared with the general elevated roof, the design of the first connecting hole 11 and the second connecting hole 12 on the supporting partition 2 enables the lower chamber to form an elevated layer with drainage and ventilation functions, thereby improving the natural ventilation and heat insulation effect, enhancing the roof drainage performance, and also improving the water storage capacity.

[0085] In general, the ecological planting roof module designed in this application not only improves the thermal insulation performance of the building roof, but also improves the ecological performance to further reduce the building energy consumption.

[0086] The above is an embodiment of an ecological planting roof module provided in the embodiment of the present application. The following is an embodiment of an ecological planting roof module provided in the embodiment of the present application. For details, please refer to Figures 1 to 6 .

[0087] Based on the solution of the above embodiment 1:

[0088] Furthermore, if Figure 2 As shown, for the design of the planting module 4, it includes planting soil and plants planted on the planting soil. The planting soil laid in the upper chamber can be light planting soil, and the green plants can be mosquito-proof and drought-resistant plants such as Sedum. The laying thickness of the planting soil can be 200mm. Taking the square upper chamber design as an example, the size of the upper chamber can be 1200mm long * 1000mm wide * 200mm deep.

[0089] Furthermore, a filter module 5 is laid at least at the bottom of the upper chamber, and the filter module 5 is used to prevent the planting soil from flowing out from the first connecting hole 11 or the second connecting hole 12, but can allow water in the planting soil to pass through. By setting the filter module 5, the soil can be prevented from being lost along with the water, and the filter module 5 can specifically be a geotextile with good water permeability. Preferably, the filter module 5 can be laid throughout the upper chamber without limitation.

[0090] Furthermore, if Figure 3 As shown, the ventilation module 7 is designed to include a ventilation pipe 71 and a fan 75 .

[0091] The ventilation pipe 71 is inserted in the planting module 4, specifically inserted in the planting soil and the two ends extend out of the module body 1, and the fan 75 is connected to one end of the ventilation pipe 71. The fan 75 is an exhaust fan 75, and the exhaust pipe of the air-cooled heat pump unit can also be connected to the other end of the ventilation pipe 71, so that the 19°C~24°C wind discharged by the air-cooled heat pump unit is introduced into the ventilation pipe 71 and then discharged through the exhaust fan 75. The temperature is lower than the outdoor air temperature in summer. In the process, heat exchange is carried out with the heat in the planting soil, realizing the residual cold utilization of the heat pump exhaust, and also improving the thermal insulation performance, realizing the integrated coupling utilization of active ventilation and passive ecological thermal insulation.

[0092] Furthermore, the number of ventilation pipes 71 can be designed to be multiple. Specifically, the diameter and number of ventilation pipes 71 can be set according to the thickness of the planting soil and the insulation requirements. In the present application, three through-type ventilation pipes 71 are interspersed in the planting soil, and the arrangement method can be an interval array setting, without specific limitation.

[0093] Under the design of multiple ventilation pipes 71, the ventilation module 7 is also designed to include a first collector pipe 72 and a second collector pipe 73. The first collector pipe 72 is installed outside the module body 1 and connected to one end of the multiple ventilation pipes 71; the second collector pipe 73 is installed outside the module body 1 and connected to the other end of the multiple ventilation pipes 71, and the fan 75 is connected to the first collector pipe 72.

[0094] Specifically, one end of the first manifold 72 is connected to the fan 75, and the other end is closed. One end of the multiple ventilation pipes 71 is connected to the side wall of the first manifold 72; one end of the second manifold 73 is closed, and the other end is provided with a multi-way component 74 (such as a four-way pipe / four-way joint, etc.), which can be easily connected to the heat pump exhaust pipe or the ventilation pipe 71 of another roof module unit. The diameter of the three ventilation pipes 71 is 110mm and the length is 1200mm. The diameters of the first manifold 72 and the second manifold 73 are both 110mm. The fan 75 can be designed to have a diameter of 110mm and an air volume of 160m 3 / h, 10W power photovoltaic wind turbine 75, its model is JYF-110-4.

[0095] Furthermore, if Figure 1 as well as Figure 2 As shown, the water storage module 3 can be a trough structure, which can be integrally formed with the support baffle 2. The support baffle 2 and the water storage module 3 can be made of waste recycled plastics through a mold, which can realize the recycling of materials. The volume of the water storage module 3, the area of ​​the second connecting hole 12 of the support baffle 2, the overhead height of the overhead chamber formed by the lower chamber, the water permeability, the water storage capacity, etc. are determined through calculation analysis and experimental testing. For example, its water storage capacity can meet the plant growth requirements of the module without rainfall for two consecutive months under subtropical climate conditions, and the water permeability can meet the water permeability requirements of the module in heavy rain without restrictions.

[0096] Furthermore, if Figure 6 As shown, the module body 1 is formed by assembling a plurality of module panels, which can be prefabricated from PE materials. Taking the module body 1 as a cube structure as an example, the module panels can be designed in four pieces, and the module panels are connected by prefabricated buckles to facilitate rapid assembly on site.

[0097] A plurality of module panels enclose an arrangement cavity, at least two module panels are provided with drain ports 13, and more module panels are provided with drain ports 13, which can improve the drainage effect and the ventilation effect of the overhead space. The height of the drain port 13 can be consistent with the bottom height of the supporting partition 2. Taking the supporting partition 2 relative to the roof structure layer height of 110m as an example, the height of the drain port 13 is also 110mm to meet the requirements of the bottom ventilation pipe 71. The specific dimensions of two of the four module panels can be 1240mm long*350mm high*10mm thick, and the specific dimensions of the other two module panels are 1040mm long*350mm high*10mm thick.

[0098] Furthermore, a root isolation module 6 is laid at the bottom of the arrangement cavity, which is specifically made of HDPE material and has the main function of preventing plant roots from damaging the roof structure and playing a waterproof role.

[0099] Furthermore, the present application is designed with a photovoltaic power generation unit.

[0100] The photovoltaic power generation unit is electrically connected to the ventilation module 7. The photovoltaic power generation unit includes a photovoltaic bracket 81 and a photovoltaic panel 82. The photovoltaic bracket 81 is connected to the module body 1. The photovoltaic panel 82 is installed on the photovoltaic bracket 81. The size of the photovoltaic panel 82 can be 1100mm long*250mm wide*5mm. The photovoltaic bracket 81 and the photovoltaic panel 82 are matched in a separate overlapping manner.

[0101] like Figure 6 As shown, there are at least two roof module units in the present application, and multiple roof module units can be assembled to meet the needs of laying larger sizes.

[0102] A photovoltaic power generation unit is provided between two adjacent roof module units, and an overhead area is formed under the photovoltaic power generation unit, which can be used to set up a manifold. At the same time, it is also convenient for the photovoltaic panel 82 to connect to the fan 75 and drive the fan 75. The power of the photovoltaic panel 82 can be 13w, ensuring that a 10w fan 75 can be driven.

[0103] This application tests and compares the designed ecological planting roof module with other roof modules:

[0104] Design module: The ecological planting roof module designed for this application is specifically a design combination of soil planting + soil active ventilation pipe + overhead water storage.

[0105] The comparison modules are as follows:

[0113]

[0114] It can be seen from the table that the ecological planting roof module designed in this application has a very good thermal insulation effect.

[0115] This application integrates water storage, planting, photovoltaics, ecology, insulation, and heat pump waste heat utilization into an ecological planting building roof module, which can meet the needs of building roof insulation and ecology, achieve roof insulation and building energy conservation, increase the utilization rate of rainwater storage on urban building roofs, improve the waste heat utilization and heating efficiency of heat pumps, and improve the ecological level of urban building roofs.
