Description

Technical Field

[0001] The invention relates to an energy-saving building and a use method thereof, and belongs to the technical field of building. Background Art

[0002] Energy-saving buildings, which prioritize direct access to natural energy for heating, have been widely adopted in the construction industry. Passive buildings, among others, capture, store, and utilize natural energy in a natural manner through the rational arrangement of building orientation, floor plan, and exterior form, the ingenious manipulation of interior and exterior forms, the rational design of the building structure, and the careful selection of building materials. To design energy-saving buildings with practical application, solar energy utilization technologies can be integrated into the building.

[0003] Fresnel lens technology is a design solution that makes lenses lighter and thinner. This approach removes as much optical material as possible while preserving the curvature of the lens surface, collapsing the continuous surface onto a flat surface. This makes the lens lighter and thinner. The surface of this lens is composed of a series of sawtooth-shaped grooves, with an elliptical arc at the center. Each groove has a different angle from the adjacent grooves, but all focus light to form a central focal point, which is also the focal point of the lens. Each groove can be regarded as an independent small lens, adjusting the light into parallel light or focusing it.

[0004] Borne-type structural coatings are a type of structural coating that can store solar energy. Under ultraviolet light, the coating can undergo a diene cycloaddition reaction and convert into its photoisomer - tetracycloheptane with extremely high tension. Solar energy is stored in the form of tension energy; when there is no sunlight, tetracycloheptane is reversed and converted back to borne-type, and the tension energy is released in the form of heat.

[0005] There is no technical solution in the existing technology that integrates Fresnel lens technology and norbornadiene coating technology and uses them in buildings, so as to improve the indoor thermal environment quality and human comfort without consuming energy, while simplifying the building construction process and reducing construction costs. Summary of the Invention

[0006] The purpose of the present invention is to provide an energy-saving building assembled from thermal collection boxes and a method for using the same. In cold seasons, the Fresnel lens principle is used to collect solar energy, and a norbornadiene structural coating and the water contained in the thermal collection boxes are used to store solar energy. Through the design of the thermal collection boxes, solar energy is fully utilized, allowing the building to collect and store heat during the day and fully utilize the stored heat at night. In hot seasons, the water contained in the thermal collection boxes can also be used to absorb cold energy at night and release it indoors during the day, thereby improving the indoor thermal environment. In addition, the thermal collection boxes can be used as vents to enhance building ventilation. The energy-saving building assembled from thermal collection boxes can switch operating conditions according to the season and day and night, improving the quality of the indoor thermal environment and human comfort without consuming energy.

[0007] To this end, the present invention provides an energy-saving building assembled from heat collecting boxes, wherein the heat collecting box is in the shape of a hexagonal prism with six parallel hexagonal prisms, the front facade and the rear facade of the heat collecting box are parallel to each other and are composed of an isosceles trapezoid and a rectangle, the lower base of the isosceles trapezoid is equal to the length of the rectangle, and a circular Fresnel lens is provided in the middle of the isosceles trapezoid on the front facade of the heat collecting box; in the side elevation view of the heat collecting box, the projection of the Fresnel lens is jagged; other parts of the front facade of the heat collecting box are coated with a norbornadiene structural coating; a ventilation and water inlet is provided on the rear facade of the heat collecting box; a switchable sealing cover is provided at the wide end and the narrow end of the heat collecting box; a copper heat sink is fixed inside the heat collecting box between the wide end and the narrow end; in addition to cooperating with the Fresnel lens to concentrate and dissipate heat, the heat sink can also promote water convection inside the heat collecting box, thereby improving the heat storage effect of the heat collecting box; The heat collecting box includes two types: one filled with water and the other not filled with water; The flow of water or air therein can be accelerated, thereby improving the heat convection effect in the heat collecting box 1.

[0008] The main body of the building is in the shape of a quadrangular pyramid and includes: Base: Set at the bottom of the main body of the building. A row of non-water-filled heat collecting boxes are set on each of the four sides of the base, and the Fresnel lenses on the corresponding heat collecting boxes face upwards; the four edges of the main body of the building are equipped with building frame side supports; Side: The four sides of the building are made of tightly connected water-filled solar collector boxes. The Fresnel lenses of the corresponding solar collector boxes face diagonally upward. The solar collector boxes are arranged with their wide ends touching each other, and their narrow ends touching each other. Every two solar collector boxes connected wide end to wide end form a solar collector unit. The ventilation and water inlet of the solar collector boxes are blocked with plugs to prevent water leakage. Ventilation column: Set in the center of the main building, the ventilation column consists of several heat collecting boxes without fins and filled with water, arranged from bottom to top. The surface where the Fresnel lens is located is perpendicular to the ground. The upper end of the ventilation column is higher than the top of the square pyramid. The ventilation and water inlet of each heat collecting box that is higher than the top of the square pyramid is equipped with a trumpet-shaped ventilation guide to enhance the ventilation effect of the main building. Switchable sunshade curtains: located on the four sides of the building, with a width equal to that of a heat collecting unit, and each side has several switchable sunshade curtains; Door: It is set on any side of the building body and consists of a non-water-filled heat collection unit.

[0009] A further improvement of the present invention is that the middle part of the heat sink is circular. After installation, the circle is located at the focus of the Fresnel lens. The two sides of the heat sink are long strips, which are respectively connected to the wide end and narrow end of the heat collecting box; the periphery of the circular part of the heat sink and the two sides of the long strip part are densely arranged sheet structures, which spread out radially to the surroundings to enhance its heat dissipation area.

[0010] A further improvement of the present invention is that a gauze cover is provided at the position of the sealing cover to prevent mosquitoes from entering.

[0011] The heat collecting box is preferably made of a hard plastic with high transparency, and is filled with water and salt can be added to prevent freezing.

[0012] A further improvement is that the inclination of the four side surfaces of the building body is 45°-60°.

[0013] A further improvement of the present invention is that each sunshade curtain is provided with a sunshade curtain rotating shaft and a sunshade curtain support at the uppermost end, and two sunshade curtain rotating shafts and sunshade curtain supports at the lowermost end.

[0014] A further improvement of the present invention is that triangular connectors are used to connect the arrangement gaps between the heat collecting boxes on the four sides of the building body.

[0015] A further improvement of the present invention is that the ventilation water inlet and the sealing cover are electrically controlled to be opened and closed.

[0016] The method for using the energy-saving building assembled by heat collecting boxes includes one of the following four working conditions: Working condition 1, winter daytime working condition: When the sunshade curtain is opened, sunlight is focused by the Fresnel lens on the solar collector box on the side of the building body, concentrating the heat on the heat sink. The heat sink transfers the heat to the water inside the solar collector box, and the water stores the heat. At the same time, sunlight shines on the norbornadiene structure coating on the solar collector box on the side of the building body. The norbornadiene structure absorbs ultraviolet rays, converts it into tetracycloheptane, and stores solar energy. In addition, the short-wave part of the sunlight can penetrate the water in the solar collector box and enter the room by radiation, while the long-wave radiation in the room is blocked by the water in the solar collector box. The greenhouse effect can be used to further increase the indoor air temperature. The door uses the Fresnel lens to focus the heated air inside and discharge it into the room.

[0017] If ventilation is required, open the sealed cover of the non-water-filled solar collector box located at the base surrounding the main body of the building on the sunny side and use it as an air inlet. The sunlight is focused through the Fresnel lens on the solar collector box, concentrating the heat on the heat sink. The heat sink transfers the heat to the air inside the solar collector box to increase the inlet air temperature; open the ventilation column, a ventilation water inlet located on the outdoor solar collector box at the top of the building, and a ventilation water inlet located on the indoor solar collector box at the top of the building, and ventilate in combination with the air inlet.

[0018] Working condition 2, winter night working condition: When the sunshade curtain is closed, tetracycloheptane gradually transforms into a norbornadiene structure and releases heat to heat the water inside the solar collector box. The water inside the solar collector box gradually releases heat and transfers it to the indoor air through heat convection, and the indoor air is heated.

[0019] Working condition three, summer daytime working condition: When the sunshade curtain is closed, the water temperature inside the thermal box is lower than the indoor air temperature, which can gradually absorb the heat in the indoor air, store the heat in the thermal box, and delay the increase in indoor air temperature.

[0020] If ventilation is required, open the sealing cover of the non-water-filled heat collecting box located at the base surrounding the main body of the building on the shady side and use it as an air inlet; open the ventilation water inlet located on the outdoor heat collecting box at the top of the building and a ventilation water inlet located on the indoor heat collecting box at the top of the building, and combine the air inlet for thermal pressure ventilation.

[0021] Working condition 4, summer night working condition: Open the sunshade curtain. Since the water temperature inside the thermal box is higher than the outdoor air temperature, it can gradually release heat to the outdoor air through convection and radiation, releasing the heat from the thermal box.

[0022] If ventilation is required, open the sealed cover of the non-water-filled heat collecting box located at the base surrounding the main body of the building and use it as an air inlet; open the ventilation water inlet on the outdoor heat collecting box at the top of the building and a ventilation water inlet on the indoor heat collecting box at the top of the building, and combine the air inlet for thermal pressure ventilation.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. The solar collector box can participate in the construction of the building as the main structure, improving the integration problem of traditional solar energy collection system and water wall system with the building.

[0024] 2. The solar collector box has low cost, small size and is easy to install and disassemble. It can improve the problems of traditional water storage walls such as easy leakage, difficult maintenance and high cost.

[0025] 3. This product can switch working conditions between different seasons and day and night through the design of the building structure, basically without any energy consumption, and can adjust the temperature indoors of the building to create a comfortable thermal environment.

[0026] 4. This product can be combined with the design of the solar collector box, using the solar collector box as a vent to enhance building ventilation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] like Figures 1-12The figure shows a solar building assembled from solar collector boxes. The box 1 is a hexagonal prism, made of highly transparent rigid plastic. Its six prisms are parallel, and its front and rear facades are parallel and formed from an isosceles trapezoid and a rectangle. The lower base of the isosceles trapezoid is equal to the length of the rectangle. A circular Fresnel lens 101 is positioned in the center of the isosceles trapezoid on the front facade of the box 1. This lens 101 is integrally formed with the transparent rigid plastic that makes up the box 1. In a side elevation view, the projection of the Fresnel lens 101 appears jagged. The rest of the front facade of the box 1 is coated with a norbornadiene-based structural coating 102. A ventilation and water inlet 103 is located on the rear facade of the box 1. Sealing covers 104 and screen covers 105 can be installed at the wide and narrow ends of the box 1. The screen cover 105 can prevent mosquitoes from entering when the sealing cover 104 of the heat collecting box 1 is opened. A copper heat sink 106 is fixed between the wide end and the narrow end of the heat collecting box 1. The middle part of the heat sink 106 is circular, and after installation, it is located at the focus of the Fresnel lens 101. The two sides of the heat sink 106 are long strips, which are respectively connected to the wide end and narrow end of the heat collecting box 1. The periphery of the circular part and the two sides of the long strip part of the heat sink 106 are densely arranged sheet structures, which spread out radially to enhance its heat dissipation area. The interior of the heat collecting box 1 can be filled with water or not as needed, and salt is added to the water body inside to prevent freezing. The Fresnel lens 101 is located in the middle of the isosceles trapezoid of the heat collecting box 1, which can accelerate the flow of water or air in the heat collecting box 1 and enhance the heat convection effect in the heat collecting box 1. In addition to cooperating with the Fresnel lens 101 to focus and dissipate heat, the heat sink 106 can also promote convection of water inside the heat collecting box 1 and enhance the heat storage effect of the heat collecting box 1 .

[0051] like Figures 13-18 As shown, the main body of the building is in the shape of a quadrangular pyramid similar to a pyramid.

[0052] The bottom of the building is a base 2. Each of the four sides of the base 2 is provided with a row of non-water-filled heat collecting boxes 1, with Fresnel lenses 101 on the heat collecting boxes 1 facing upward. Side supports 3 of the building frame are provided at the four edges of the building.

[0053] The four sides of the main building are inclined at 45° to 60° and are composed of densely arranged solar collector boxes 1. The Fresnel lenses 101 of the solar collector boxes 1 face diagonally upward. The solar collector boxes 1 are arranged so that the wide ends touch the wide ends and the narrow ends touch the narrow ends. Every two solar collector boxes 1 are connected wide-end to wide-end to form a solar collector unit. The gaps between the solar collector boxes 1 are connected using triangular connectors. Each solar collector box 1 on the four sides is filled with water, and the circular ventilation and water inlet 103 of the solar collector box 1 is blocked with a plug to prevent water leakage.

[0054] A ventilation column 4 is located in the center of the main building. It consists of several unfilled heat collector boxes (1) with their fins 106 removed, arranged from bottom to top. The surface of each box's Fresnel lens 101 is perpendicular to the ground. The top of the ventilation column 4 is elevated a certain distance above the top of the pyramid. Furthermore, trumpet-shaped ventilation ducts 5 are installed on the ventilation and water inlet 103 of each box above the pyramid's top, enhancing ventilation in the main building.

[0055] Several vertical sunshade curtains 6 are installed on the outside of the four sides of the building body. The width is the same as that of a heat collecting unit. Each side has several openable sunshade curtains. The top end of each sunshade curtain 6 is provided with a sunshade curtain shaft 7 and a sunshade curtain support 8. The bottom end is provided with two sunshade curtain shafts 7 and sunshade curtain supports 8. The sunshade curtain 6 can be opened or closed by rotating the sunshade curtain shaft 7.

[0056] A door 9 can be provided on any side of the building body. The door 9 is composed of a heat collecting unit that is not filled with water.

[0057] Four working conditions of this product: 1. Daytime working conditions in winter: like Figure 19 As shown, when the sunshade curtain 6 is opened, sunlight is focused by the Fresnel lens 101 on the heat collecting box 1 on the side of the building body, concentrating the heat on the heat sink 106. The heat sink 106 transfers the heat to the water inside the heat collecting box 1, and the water stores the heat. On the other hand, sunlight shines on the norbornadiene structure coating 102 on the heat collecting box 1 on the side of the building body. The norbornadiene structure absorbs ultraviolet rays, converts it into tetracycloheptane, and stores solar energy. In addition, the short-wave portion of sunlight can penetrate the water in the heat collecting box and enter the room by radiation, while the long-wave radiation in the room is blocked by the water in the heat collecting box. By utilizing the greenhouse effect, the indoor air temperature can be further increased. The door 9 is composed of a heat collecting unit that is not filled with water, and the Fresnel lens 101 can also be used to focus and heat the air therein and discharge it into the room.

[0058] If ventilation is needed, open the sealed cover 104 of the waterless heat collection box 1 located on the sun-facing side of the building, surrounding the main structure and located on base 2. Use it as an air inlet. Sunlight is focused by the Fresnel lens 101 on the heat collection box 1, concentrating the heat on the heat sink 106. The heat sink 106 transfers the heat to the air inside the heat collection box 1, raising the incoming air temperature. Open the ventilation column 4, one ventilation water inlet 103 on the outdoor heat collection box 1 at the top of the building, and one ventilation water inlet 103 on the indoor heat collection box 1 at the top of the building, combining them for ventilation.

[0059] 2. Winter night working conditions: like Figure 20As shown, when the sunshade curtain 6 is closed, the tetracycloheptane gradually converts into a norbornadiene structure and releases heat to heat the water inside the heat collecting box 1. The water inside the heat collecting box 1 gradually releases heat and transfers it to the indoor air through heat convection, thereby heating the indoor air.

[0060] 3. Summer daytime working conditions: like Figure 21 As shown, when the sunshade curtain 6 is closed, since the water temperature inside the heat collecting box 1 is lower than the indoor air temperature, it can gradually absorb the heat in the indoor air, store the heat in the heat collecting box, and delay the increase in indoor air temperature.

[0061] If ventilation is required, open the sealed cover of the waterless heat collection box 1 on the base 2 surrounding the building body on the shady side and use it as an air inlet. Open the ventilation water inlet 103 on the outdoor heat collection box 1 at the top of the building and the ventilation water inlet 103 on the indoor heat collection box 1 at the top of the building on the ventilation column 4, and combine them to achieve heat pressure ventilation.

[0062] 4. Summer night working conditions: like Figure 22 As shown, when the sunshade curtain 6 is opened, since the water temperature inside the heat collection box 1 is higher than the outdoor air temperature, it can gradually release heat to the outdoor air through convection and radiation, thereby releasing the heat from the heat collection box.

[0063] If ventilation is needed, open the sealed cover of the non-water-filled heat collection box 1 located on the base 2 surrounding the building body, using it as an air inlet. Open the ventilation water inlet 103 on the outdoor heat collection box 1 at the top of the building, as well as another ventilation water inlet 103 on the indoor heat collection box 1 at the top of the building, and combine these inlets for heat pressure ventilation. Preferably, the ventilation water inlet 103 and sealed cover 104 on the heat collection box 1 can be electrically controlled.

[0064] The present invention is not limited to the above-mentioned embodiments. On the basis of the technical solutions disclosed in the present invention, those skilled in the art can make some substitutions and modifications to some of the technical features therein according to the disclosed technical content without creative labor, and these substitutions and modifications are all within the protection scope of the present invention.
