The application is a divisional application of a regression reflection energy-saving outer wall system patent applied by application number 2019101733341, application date 2019.03.11.
Technical Field
The invention relates to the technical field of building walls, in particular to a retro-reflection energy-saving outer wall system.
Background
With the continuous increase of the economy of China, the continuous improvement of the quality of life of the China and the continuous rapid development of cities, the building energy consumption becomes an important component of the total energy consumption of China. Therefore, building energy conservation becomes a great means for realizing sustainable development in China.
In summer, solar radiation is one of the largest external disturbances affecting indoor thermal environment, so that not only is indoor thermal comfort reduced, but also building energy consumption loss is increased. The heat brought to the building by the solar radiation causes the surface temperature of the external enclosure structure to rise, and the heat is transferred to the indoor through the external enclosure structure of the building to become the cold load of the building, so that the energy consumption of the air conditioning system is increased. As the building coverage increases, the urban centers will absorb more and more heat from solar radiation, and the heat island effect increases year by year, so that the temperature in the urban centers is higher than that in suburban areas. For most residents in the modern, the indoor thermal comfort, the electric energy consumption of an air conditioner and a heater and the green and environmental protection functions of the building are important concerns. In areas hot in summer and warm in winter, the building external protective structure is irradiated by a large amount of solar radiation, so that a large amount of cold load is brought indoors, the building energy consumption is increased, and the service life of indoor furniture is also shortened. This affects the quality of life of the residents in China to a great extent.
Therefore, how to improve the temperature regulation function of the outer wall becomes a problem which needs to be considered frequently when modern building design is carried out.
CN108895583A discloses a building outer wall cooling system and a cooling method, belonging to the technical field of temperature regulation of building outer wall structures. This building outer wall cooling system includes that the rainwater collects deposits device, drenches water net and a plurality of shower head, and the device is deposited through water pump and shower head intercommunication to the rainwater collection, and the building outer wall surface is arranged in to the drenching net cloth, and the rainwater is followed the shower head blowout, drenches and forms the water film on the drenching net. The cooling method comprises the following steps: acquiring the rainwater temperature in a heat-preservation water tank of a rainwater collecting and storing device and the surface temperature of the outer wall of a building; when the difference value between the surface temperature and the rainwater temperature exceeds a threshold value, the water pump is started, the rainwater in the heat-preservation water tank is sprayed on the water spraying net through the spray header, heat exchange is carried out between the rainwater and the building outer wall, and the building outer wall is cooled.
The outer wall cooling system of this current patent can utilize the rainwater of collection well to spray and realize the cooling of outer wall, but its cooling accuse temperature mode is single, and cooling accuse temperature effect is comparatively limited.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide an outer retaining wall structure which has the effects of light weight, heat preservation and easy installation, can better reflect solar illumination, and has simple preparation method operation, strong feasibility and good reliability. The retro-reflection energy-saving outer wall system based on the outer retaining wall structure is more excellent in cooling effect; and the air conditioner has the effects of spray cooling, heat insulation, heat preservation, convection cooling and the like, so that the cold load of the air conditioner is reduced, and the purposes of energy conservation and emission reduction are achieved.
In order to solve the technical problems, the invention adopts the following technical scheme:
a retro-reflection energy-saving outer wall system comprises a vertically arranged wall body, wherein a spray head system is arranged on the wall body, the spray head system comprises a water collecting tank arranged on a roof, a water storage tank connected with the water collecting tank and a spray head arranged outside the wall body, the spray head is connected with the water storage tank by adopting a water spraying pipeline, a control valve is arranged on the water spraying pipeline, and the control valve is connected with a controller; the heat insulation structure is characterized by further comprising an outer vertical retaining wall, wherein the outer vertical retaining wall is arranged on the outer side of the wall at intervals, and a heat insulation space which is communicated with the outer wall in the circumferential direction is formed between the outer retaining wall and the wall.
Therefore, on the basis of the existing wall rainwater spraying system, the external baffle wall is additionally arranged, so that the wall can be prevented from being directly exposed to the sun, the heat insulation effect is achieved, and meanwhile, under the action of the spray head, the air outside the external baffle wall generates the up-and-down convection effect, and the wall body heat can be better carried away in high-temperature weather.
Further, the spray head is an atomizing spray head. Therefore, the spray head sprays atomized water, and the cooling effect brought by the sprayed water mist is improved.
Furthermore, a water collecting position of the water collecting tank is also provided with a filtering device, and a water outlet end of the filtering device is connected with a water storage tank above through a pressure water pump and a water pumping pipeline.
Like this, can filter collecting the rainwater, avoid blockking up.
Further, the water storage tank is connected with a municipal water pipe.
Like this, when the rainwater is not enough, can replenish the water source through municipal water pipe.
Furthermore, a temperature probe is arranged outside the wall body and connected with the controller.
Like this, can automated inspection wall body outside temperature, when the temperature was greater than the default, start shower nozzle spray cooling promptly, improved degree of automation.
Furthermore, the spray heads are arranged at the lower end of the outer side of the outer retaining wall in rows and close to the ground, and the outlet direction of the spray heads is arranged right opposite to the outer retaining wall.
This is because in hot summer, when the temperature is too high, the temperature of the ground is always higher than the temperature of the air, and therefore the temperature of the air near the ground is always higher than the temperature of the air far from the ground. The water overcomes the pipeline resistance and provides the pressure required by atomized water through the self gravity action, and the atomizing nozzle atomizes the water and then sprays the atomized water at the lower end of the outer retaining wall close to the ground, so that the heat of the ground and the outer retaining wall is absorbed more easily, and the water is evaporated. This causes the air of the lower portion to increase the latent heat, but the temperature of the air of the lower portion hardly changes, so that the total heat increase of the air of the lower portion is known from the total heat = sensible heat + latent heat. Because the heat always moves from the place with larger heat to the place with smaller heat and the heat exchange process is always accompanied with mass exchange, the lower air with higher heat moves upwards due to the heat absorbed by the outer retaining wall and the ground, and the effect of convective heat exchange is promoted. Meanwhile, the spray head is arranged on the outer side of the outer baffle wall, so that the damage to a wall structure caused by overhigh humidity for a long time in a heat insulation space can be avoided. During specific implementation, the spray head can be arranged at other positions, such as the upper end of the heat insulation space and even the inner part of the outer retaining wall, and the like, and the practical scheme is adopted.
Further, the retro-reflection energy-saving outer wall system is preferably arranged on a wall body on the west side of the building, because the west outer wall of the building in summer receives the largest radiation heat, and the effect of cooling and energy saving can be exerted to the greatest extent when the system is arranged on the west outer wall of the building.
Further, the outer retaining wall comprises an expanded polystyrene board layer, a bonding layer, a reflective coating layer, glass beads and a waterproof layer from inside to outside; the outer retaining wall is fixedly installed on a vertically arranged installation framework, and the installation framework is fixed on a wall body through horizontally arranged steel rivets.
Therefore, the outer retaining wall has the effects of light weight, heat preservation and easy installation, and can better reflect the sunlight. During specific implementation, the mounting framework is preferably a frame structure which is made of steel materials and is arranged vertically and horizontally, so that the structural strength and stability are guaranteed.
Further, the outer retaining wall is prepared by adopting the following preparation method, and the preparation method comprises the following steps: a, obtaining glass beads with the diameter of 3-7 mm; b, obtaining a reflective coating; further comprising: and c, arranging and fixing the glass beads on the mold in an array manner, exposing one side of the glass beads in the air, directly arranging a layer of hot melt adhesive after coating the reflective coating on one side of the glass beads exposed in the air, and bonding and fixing the glass beads coated with the reflective coating on the substrate by virtue of the hot melt adhesive.
Therefore, the glass beads are fixed firstly, then the reflective coating is sprayed, the hot melt adhesive is arranged, and then the glass beads are bonded on the substrate, so that the method has the advantages of simple operation, strong practicability and good reliability.
Preferably, the substrate is an expanded polystyrene board.
Therefore, the heat insulation plate has the advantages of light weight, good heat insulation effect and the like.
Preferably, the diameter of the glass bead is 5 mm.
If the diameter of the glass beads is too small, the preparation is inconvenient; if the diameter of the glass beads is too large, the gaps among the glass beads are too large, the reflectivity is greatly reduced, and the occupied space is increased, so that the preparation of the glass beads with the diameter of 5mm is selected as the optimal.
The glass beads are prepared by the following method, wherein quartz sand 53% in mass ratio, feldspar 23% in mass ratio, borax 14% in mass ratio, sodium carbonate 8% in mass ratio, fluorite and sodium nitrate which are other auxiliary raw materials account for 1% in mass ratio are crushed and mixed uniformly, the temperature is raised to 1600 ℃ in a glass melting furnace, a molten mass is formed after the reaction is completed, the molten mass is led out to a spherical mold with the diameter of 5mm to be molded and cooled, and the glass beads with the diameter of 5mm can be obtained preliminarily.
The glass beads prepared by the method have the advantages of simple preparation process, high yield, no bubbles in the finished product of the glass beads, less impurities, small deviation of the ball diameter, high qualified rate of the finished product and the like. Of course, in practice, other existing techniques may be used to prepare the glass beads or to purchase the finished glass beads directly.
As optimization, before the glass beads are used, the coupling agent with the concentration of 1.2% is adopted to modify the surfaces of the glass beads.
Therefore, the surface of the glass bead is changed from hydrophilic to oleophilic, and the negative influence caused by hydrophilic is avoided.
Preferably, the reflective coating is prepared by the following method: mixing a coupling agent KH560 with ethanol according to the mass ratio of 1:1, adding deionized water to prepare a silane coupling agent aqueous solution with the concentration of 5%, uniformly stirring, adding acetic acid into the solution to make the solution weakly acidic (pH is approximately equal to 5), and obtaining a binder after the coupling agent is hydrolyzed for a certain time and shows cohesiveness; and then adding a wetting agent into part of flake aluminum powder or Qinbai powder filler, carrying out magnetic stirring, slowly adding a certain amount of the binder in 1 hour of the magnetic stirring until the binder is in a fluid state after the stirring is finished, and then putting the mixture into a spraying device for later use.
The prepared reflective coating has good fluidity, is easy to spray and guide into a sealed spraying device for storage, and has good binding property with the glass beads on one side and the hot melt adhesive on the other side. In practice, the existing reflective coating preparation technology can be directly adopted, or the existing reflective coating product can be directly purchased for use.
In the step c, the mould is a mould sieve made of elastic materials, sieve pores are uniformly arrayed on the mould sieve, and the diameter of the sieve pores is less than the diameter of the glass beads by 0.1-1mm (optimally 0.5 mm); and c, spreading glass beads on a mould screen and passing through a vibrating mould screen, enabling the lower half parts of the glass beads to be embedded into the screen holes and to be fully distributed in the screen holes of the mould screen, removing redundant glass beads on the surface of the mould screen, pressing the glass beads embedded into the screen holes into a half of the screen holes by using a pressing plate, integrally spraying a reflective coating on one side of the glass beads exposed in the air, paving a layer of hot melt adhesive to cover the exposed parts of the glass beads after the high-reflective coating is solidified into a high-reflective film, bonding and fixing a base material plate with the same area as the range of the screen holes on the outer side of the hot melt adhesive until the hot melt adhesive is solidified, and removing the glass beads from the mould screen to obtain the retro-reflective plate.

Further, the inner surface layer of the mold sieve is made of rubber materials, the rubber materials of the mold sieve are heated before and/or in the embedding process of the glass beads, so that the rubber materials are softened, the glass beads are embedded into the sieve pores and pressed into the sieve pores with the diameter of one half, after the rubber materials of the mold sieve are cooled and hardened, the reflective coating is sprayed, and finally, before demolding, the rubber materials are heated again, so that the rubber materials are softened, and then demolding is carried out.
Like this, after mould sieve rubber materials softened, can make things convenient for more in glass bead can comparatively firmly imbed the sieve mesh under the effect of vibration, avoid making the glass bead of embedding fall out together when cleaing away unnecessary glass bead, make things convenient for the clamp plate to impress the glass bead of embedding sieve mesh once more in half diameter to the sieve mesh simultaneously, then wait to cool back spraying reflecting material again and lay the hot melt adhesive. The glass beads can be fixed in the process, and the effect of the reflective coating is better ensured so as to ensure the reflective effect of the prepared material. And the glass beads can be conveniently removed from the sieve pores by reheating before demoulding.
Further, the method is prepared by adopting the following reflecting plate production device, wherein the reflecting plate production device comprises a base, one side of the base is vertically provided with an upright post, the middle part of the upright post is horizontally and outwards fixedly provided with a mold sieve supporting arm, the front end of the mold sieve supporting arm is hinged with a mold sieve clamp extending forwards, a mold sieve is horizontally arranged in the mold sieve clamp, and a vibration generation device is also arranged on the mold sieve clamp; a telescopic mechanism mounting arm is horizontally and fixedly arranged on the stand column below the mold screen support arm, a telescopic mechanism for controlling the inclination of the mold screen is arranged at the front end of the telescopic mechanism mounting arm, the telescopic end of the telescopic mechanism for controlling the inclination of the mold screen extends upwards and is hinged below a mold screen clamp, the mold screen is rectangular as a whole, one side, away from the stand column, of the mold screen is an open side, and the other three sides of the mold screen are fence sides provided with upward fences; a pressing plate mounting arm is horizontally arranged on the stand column above the mold screen support arm, one end of the pressing plate mounting arm can be matched on a sliding rail vertically arranged on the stand column in a vertically sliding mode, a pressing plate is horizontally and fixedly arranged below the other end of the pressing plate mounting arm, and the pressing plate is arranged over against the range of the screen holes in the mold screen; the top plate of stand is fixed in to clamp plate top parallel arrangement one end, and the roof lower surface is provided with the telescopic machanism for the clamp plate control just downwards to clamp plate middle part position, and the lower extreme of the telescopic machanism for the clamp plate control is connected on clamp plate installation arm.
Thus, when the device is used for preparing the reflecting plate, modified glass beads are poured into a heated mould sieve from one side close to the upright column, then the mould sieve is driven by the vibration generating device to vibrate, so that the glass beads are spread and correspondingly fall into sieve pores, meanwhile, the mould sieve is controlled to tilt and is controlled to retract by the telescopic mechanism, so that the open side of the mould sieve is gradually inclined downwards, the glass beads gradually flow to the open side of the mould sieve under the combined action of tilting and vibration and fall into all the sieve pores, redundant glass beads fall out from the open side of the mould sieve, and can be contained by a container; then controlling the telescopic mechanism for controlling the inclination of the mold screen to extend out to drive the mold screen to return to be horizontal, controlling the telescopic mechanism for controlling the pressing plate to press the pressing plate downwards, and pressing the lower half parts of the glass beads into the sieve holes of the mold; after the mold screen is cooled, spraying a reflective coating on the upper surface of the mold screen, after the highly reflective coating is solidified into a highly reflective film, laying a hot melt adhesive, bonding and fixing a substrate plate with the same area as the range of the screen holes on the upper side of the hot melt adhesive, pressing down and compacting by using a pressing plate until the hot melt adhesive is solidified, heating the mold screen again, and then removing the substrate plate together with the glass beads from the mold screen to obtain the retro-reflective plate.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Preferred embodiments: a retro-reflection energy-saving outer wall system, referring to fig. 1, comprises a vertically arranged wall body 21, a spray head system is arranged on the wall body, the spray head system comprises a water collecting tank (not shown) arranged on the roof, a water storage tank 22 connected with the water collecting tank and a spray head 23 arranged outside the wall body, the spray head 23 is connected with the water storage tank by a water spraying pipeline 24, a control valve 25 is arranged on the water spraying pipeline 24, and the control valve 25 is connected with a controller (not shown); the wall body 21 is provided with an outer retaining wall 26 which is vertically arranged, and the outer retaining wall 26 is arranged outside the wall body 21 at intervals, so that a heat insulation space which is communicated with the outside in the circumferential direction is formed between the outer retaining wall 26 and the wall body 21.
Therefore, on the basis of the existing wall rainwater spraying system, the external baffle wall is additionally arranged, so that the wall can be prevented from being directly exposed to the sun, the effects of heat insulation and heat preservation are achieved, and meanwhile, the up-and-down convection effect is generated by the air outside the external baffle wall under the action of the spray head, and the wall body heat can be better taken away in high-temperature weather.
Wherein the spray head 23 is an atomizing spray head. Therefore, the spray head sprays atomized water, and the cooling effect brought by the sprayed water mist is improved.
In practice, a filtering device (not shown) is arranged at the water collecting position of the water collecting tank (not shown), and the water outlet end of the filtering device is connected with the water storage tank above through a pressure water pump and a water pumping pipeline.
Like this, can filter collecting the rainwater, avoid blockking up. During implementation, an initial rainwater flow discarding device can be arranged on a pipeline in front of the filtering device, so that the cleanness of rainwater entering the water storage tank is better guaranteed. In addition, when the device is implemented, the water softening device is arranged on the pipeline behind the filtering device, so that inorganic salt ions in water can be removed, and the situation that the pipeline is blocked by scaling at the atomizing nozzle and the operation of the system is damaged due to overlarge hardness of rainwater is prevented.
When in operation, the water storage tank is connected with the municipal water pipe.

When the shower nozzle is implemented, the shower nozzles are arranged at the lower end of the outer side of the outer retaining wall in rows and close to the ground, and the outlet direction of the shower nozzles is arranged right opposite to the outer retaining wall.
This is because in hot summer, when the temperature is too high, the temperature of the ground is always higher than the temperature of the air, and therefore the temperature of the air near the ground is always higher than the temperature of the air far from the ground. The water overcomes the pipeline resistance and provides the pressure required by atomized water through the self gravity action, and the atomizing nozzle atomizes the water and then sprays the atomized water at the lower end of the outer retaining wall close to the ground, so that the heat of the ground and the outer retaining wall is absorbed more easily, and the water is evaporated. This causes the air of the lower portion to increase the latent heat, but the temperature of the air of the lower portion hardly changes, so that the total heat increase of the air of the lower portion is known from the total heat = sensible heat + latent heat. Because the heat always moves from the place with larger heat to the place with smaller heat and the heat exchange process is always accompanied with mass exchange, the lower air with higher heat moves upwards due to the heat absorbed by the outer retaining wall and the ground, and the effect of convective heat exchange is promoted. Meanwhile, the spray head is arranged on the outer side of the outer baffle wall, so that the damage to a wall structure caused by overhigh humidity for a long time in a heat insulation space can be avoided. During specific implementation, the spray head can be arranged at other positions, such as the upper end of the heat insulation space and even the inner part of the outer retaining wall, and the like, and the practical scheme is adopted.
In the implementation process, the retro-reflection energy-saving outer wall system is preferably arranged on a wall body on the west side of the building, because the west outer wall of the building in summer receives the maximum radiation heat, and the retro-reflection energy-saving outer wall system can play the role of cooling and energy saving to the maximum extent when arranged on the west side wall body.
When the water spraying device is implemented, the water spraying pipeline penetrates through the roof from the lower end of the water storage tank, penetrates out of the wall from the indoor, is fixed from the inner side of the wall and extends downwards to the lower end of the wall, then transversely and sequentially penetrates out of the wall and the outer retaining wall, and the spray head is installed. Therefore, the temperature rise caused by the fact that the water spraying pipeline is directly exposed to the sun can be avoided, and the spraying system can take away more heat.
During implementation, a waterproof material layer can be additionally arranged on the outer side of the wall body and on the inner side and the outer side of the outer retaining wall respectively. Therefore, the wall body can be better protected, and the service life of the wall body is prevented from being influenced by the water spray erosion of the spray head.
The outer retaining wall comprises an expanded polystyrene board layer, a bonding layer, a reflective coating layer, a glass bead layer and a waterproof layer from inside to outside; the external retaining wall 26 is fixed on a vertically arranged mounting framework 27, and the mounting framework 27 is fixed on the wall 21 by adopting a horizontally arranged steel rivet.
Therefore, the outer retaining wall has the effects of light weight, heat preservation and easy installation, and can better reflect the sunlight. During specific implementation, the mounting framework is preferably a frame structure which is made of steel materials and is arranged vertically and horizontally, so that the structural strength and stability are guaranteed.
