[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0027] Please refer to Figures 1-5 , the embodiments of the present invention include:

[0028] A humidity-controlled heat-collecting solar glass curtain wall, the structure of which includes: a wall 1, a glass plate 2, a cross bar 3, a diversion grille assembly 4, a dust-removing and humidity-control module, and a dehumidification mechanism.

[0029] The glass plate 2 is suspended outside the wall 1 through the cross bar 3, so that the wall 1, the glass plate 2 and the cross bar 3 enclose a sealed working space 5. The wall 1 is provided with a first ventilation opening 11 and a second ventilation opening 12 that penetrate through itself. The first ventilation opening 11 and the second ventilation opening 12 communicate the working space 5 and the indoor space and are located at different heights, thereby forming air convection.

[0030] Further, the wall is a dark-colored wall. Among them, the dark color refers to a color with a visual reflectance less than 30%, preferably dark gray or black, etc., to achieve a better light and heat absorption effect.

[0031] In some embodiments of the present application, a working space 5 is provided between the wall 1 and the glass plate 2.

[0032] In some other embodiments of the present application, a plurality of working spaces 5 can be formed between the wall 1 and the glass plate 2 through the cross bar 3.

[0033] Further, the first ventilation opening 11 is located at the top of the wall 1, and the second ventilation opening 12 is located at the bottom of the wall 1.

[0034] The diversion grille assembly 4 is arranged in the working space 5 between the wall 1 and the glass plate 2. The diversion grille assembly 4 includes a plurality of herringbone diversion grilles 41 arranged side by side along its width direction, so as to form a diversion structure that allows air to pass through from bottom to top between adjacent herringbone diversion grilles 41 and prevents water from passing through from top to bottom between adjacent herringbone diversion grilles 41.

[0035] Further, referring to Figure 1 , the diversion grille assembly 4 is arranged between the first ventilation opening 11 and the second ventilation opening 12 and is close to the first ventilation opening 11 located at a high place. This design shortens the moving path of the water mist sprayed by the dust-removing and humidity-control module, reduces the water mist diffused to the surface of the wall 1, and reduces the possibility of the wall 1 getting moldy.

[0036] Further, gaps allowing air to pass through are provided between adjacent herringbone diversion grilles 41, thereby allowing air to pass through from bottom to top. Moreover, the projections of adjacent herringbone diversion grilles 41 in the direction of gravity overlap with each other, thereby preventing water from passing through from top to bottom.

[0037] Further, referring to Figure 1 , the bottom edge of each herringbone diversion grille 41 extends outward to form a concave special-shaped water trough 410 capable of holding water.

[0038] Further, referring to Figure 3 , the herringbone diversion grille 41 is inclined in its own length direction, and the inclination angle is 2° to 4°. A drainage channel 42 is provided outside or below the lowest end of the herringbone diversion grille 41, so that the water mist sprayed onto the herringbone diversion grille 41 through the dust suppression and humidity control module during the day and the water vapor condensed on the surface of the herringbone diversion grille 41 at night can both converge into water flows on the surface of the herringbone diversion grille 41, and then flow along the herringbone grille 4 to the drainage channel 42.

[0039] Furthermore, referring to Figure 2 , in order to prevent water vapor from condensing on the bottom wall of the herringbone diversion grille 41 at night, resulting in condensed water dripping onto the cross bar 3, the wall or the working space 5, causing problems such as wall mildew and cross bar corrosion, the bottom wall of each herringbone diversion grille 41 is covered with an anti-condensation layer 414, and the anti-condensation layer 414 can be made of EVA foam.

[0040] Furthermore, referring to Figure 2 , each herringbone diversion grille 41 includes a first plate 411, a second plate 412 and a third plate 413 connected in sequence. The first plate 411, the second plate 412 and the third plate 413 are all inclined in the width direction of the herringbone diversion grille 41, and the inclination directions are sequentially changed in the order of the first plate 411, the second plate 412 and the third plate 413. The first plate 411 is connected to the middle of one side of the second plate 412, and the connection part of the first plate 411 and the second plate 412 forms a downward concave surface. The third plate 413 is connected to the bottom of the other side of the second plate 412, and the connection part of the second plate 412 and the third plate 413 forms an upward concave surface.

[0041] In some embodiments of the present application, the projection of the first plate 411 of one herringbone diversion grille 41 overlaps with the second plate 412 or the third plate 413 of the adjacent herringbone diversion grille 41 in the direction of gravity.

[0042] In some embodiments of the present application, the second plate 412 is used to block water mist from passing through the herringbone diversion grille 41. The second plate 412 and the third plate 413 are used to form a special-shaped water trough 410 for guiding the flow of water. The first plate 411 is used to prevent water flow from moving along the second plate 412 to its bottom wall by the wall attachment effect. The water mist on the first plate 411 converges and then flows onto the second plate 412 of another adjacent herringbone diversion grille 41, and finally flows out through the special-shaped water trough 410.

[0043] In some embodiments of the present application, the first plate 411 and the second plate 412 may be of an integral structure or may be connected by a connecting (heat-insulating) member 62; the second plate 412 and the third plate 413 may be of an integral structure.

[0044] When the dust reduction and humidity control module conducts air convection with the interior inside the Trombe wall, it dusts, humidifies or dehumidifies the air, thereby solving the problems of dusty, dry or humid indoor air.

[0045] The dust reduction and humidity control module includes an atomizing nozzle 51 arranged above the herringbone diversion grille 41. The atomizing nozzle 51 is used to spray water mist onto the top surface of the diversion grille assembly 4. The density of the atomizing nozzle 51 is configured to be able to remove the dust attached to the air passing through the diversion grille assembly 4.

[0046] In some embodiments of the present application, refer to Figure 4 , when applied to low-rise buildings, the drainage channel 42 is connected to the water tank 53 through a drain pipe 52, so that the waste water is recycled. A filter 54 is arranged between the drain pipe 52 and the water tank 53. The filter 54 can filter the dust in the waste water, so that the waste water can be reused. The water tank 53 is connected to the atomizing nozzle 51 through a water supply pipe 56 and a water pump 55, so that the waste water discharged into the interior of the water tank 53 for recycling is filtered and then sprayed out again through the atomizing nozzle 51, thereby forming a cycle of the water tank 53, the water pump 55, the atomizing nozzle 51, the diversion grille assembly 4, the drainage channel 42, the drain pipe 52 and the water tank 53.

[0047] Among them, the water tank 53 is also additionally connected to an external water source. The external water source is used to supplement water into the interior of the water tank 53, so as to make up for the water diffused and evaporated into the air. In actual use, recycled water or an external water source can be selected for spraying.

[0048] In some embodiments of the present application, refer to Figure 5, when applied to high-rise buildings, the drainage channel 42 is connected to the water tank 53 through the drain pipe 52. The water tank 53 is connected to the water source. A filter 54 is provided between the drain pipe 52 and the water tank 53. The water tank 53 is connected to the atomizing nozzle 51 on the next lower floor through the water supply pipe 56. This design can omit the water pump 55. The water source of the water tank 53 on each floor can be replenished with the waste water from the upper floor. Utilizing the height difference among the water tank 53, the atomizing nozzle 51, and the drainage channel 42, the pressurization and recycling of water can be achieved. Additionally, an external water source can also be connected.

[0049] Furthermore, the controller is respectively connected to the hygrometer set indoors and the water level gauge in the water tank 53. That is, it can judge whether to turn on the atomizing nozzle 51 for humidification according to the real-time humidity indoors, and can also judge whether to turn on the water source replenishment according to the water volume in the water tank 53.

[0050] Furthermore, valves for opening and closing the ventilation openings are installed at the first ventilation opening 11 and the second ventilation opening 12 respectively. The controller is electrically connected to the valves to open or close the air convection between the indoor and outdoor.

[0051] The working principle of the dust reduction and humidity control module includes:

[0052] During the daytime when there is sufficient sunlight, when the working space 5 between the wall 1 and the glass plate 2 is irradiated by the sun, the temperature of the outdoor air rises. The hot air rises and enters the indoor space through the first ventilation opening 11. At the same time, the cold air in the indoor space descends and enters the working space 5 through the second ventilation opening 12, gradually increasing the indoor air temperature.

[0053] The atomizing nozzle 51 sprays water mist onto the herringbone diversion grille 41. When the dust in the air passes through the herringbone diversion grille 41, the water mist adsorbs the dust and falls on the herringbone diversion grille 41, thereby reducing the dust in the indoor air. At the same time, a part of the water mist enters the indoor along with the hot air, thereby increasing the humidity of the indoor air.

[0054] During the night when there is a lack of sunlight, the temperature of the outdoor air drops. The hot air indoors enters the working space 5 through the first ventilation opening 11, and the cold air outdoors enters the indoor space through the second ventilation opening 12, thereby forming a reverse air convection, gradually reducing the indoor air temperature. When the air temperature is lower than the dew point, it condenses on the surface of the herringbone diversion grille 41, thereby reducing the humidity of the indoor air.

[0055] The above design is applicable to commercial office buildings where work is carried out during the day and there is no one at night. It can achieve the functions of dust reduction, heating and humidification during the day, and cooling and dehumidification at night for the indoor air through the day-night temperature difference between indoors and outdoors. Thus, people can work in a warm and comfortable humidity office during the day, and the office can automatically dehumidify at night, reducing the reproduction of bacteria and fungi indoors.

[0056] The dehumidification mechanism includes an evaporator connected to the herringbone diversion grille 41. The evaporator includes evaporation tubes 61 that extend along the length direction of the herringbone diversion grille 41 and are connected to the first plate 411. Refrigerant is provided inside the evaporation tubes. The evaporation tubes 61 are respectively connected to a compressor, a condenser, and an expansion valve located outside the curtain wall to form a heat pump assembly. Moreover, the first plate 411 serves as the fin of the evaporation tubes 61, so that more water droplets condense on the evaporation tubes 61 and the first plate 411, while the second plate 412 and the third plate 413 of the herringbone diversion grille 41 have a higher temperature and will not or rarely condense water droplets on their surfaces.

[0057] During use, the refrigerant used in the heat pump circulates among the compressor, the condenser, the expansion valve, and the evaporator. When the refrigerant passes through the evaporator, it absorbs the surrounding heat, causing the temperature of the herringbone diversion grille 41 to drop below the dew point. At this time, water vapor condenses into water droplets after contacting the herringbone diversion grille 41 or the first plate 411, and then flows along the herringbone diversion grille 41 to the drainage channel 42.

[0058] In some embodiments of the present application, one evaporation tube 61 is provided on each first plate 411, and the evaporation tubes 61 on each first plate are independent of each other. Each evaporation tube 61 is respectively connected to a compressor unit or shares a group of compressor units.

[0059] In some embodiments of the present application, all the first plates 411 share one evaporation tube 61. The evaporation tube has an S-shaped structure, and its two ends respectively extend out of the working space 5 and are connected to the compressor unit.

[0060] The beneficial effects of a humidity control and heat collection type solar glass curtain wall of the present invention are as follows: By setting a herringbone diversion grille with a special structure, a dust reduction and humidity control module and a dehumidification mechanism that cooperate with it, it is not only possible to perform dust reduction and humidification treatment by spraying water mist through atomizing nozzles, but also to perform dehumidification treatment by condensing water vapor with the evaporator, thereby accurately and effectively adjusting the indoor environment, improving and maintaining a good state of the indoor environment, enhancing the comfort of living and use, saving energy, reducing emissions, and being convenient to use.

[0061] The above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or equivalent process transformation made using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
