Description

Indoor space environment control method

[0001] The present invention relates to a method for controlling an indoor environment by disposing a colored, light-transmitting, heat-shielding material in a light-transmitting transparent member through which sunlight passes, thereby controlling the amount of sunlight transmitted through the light-transmitting transparent member.

[0002] BACKGROUND ART Conventionally, paints (heat-shielding paints) that are applied to existing window glass or the like to impart an ultraviolet and near-infrared blocking function to the window glass or the like have been known (for example, Patent Document 1).

[0003] JP 2013-87228 A

[0004] However, conventional heat-shielding paints are colorless and transparent, and therefore have no ability to block visible light. It is said that 45% to 49% of the sunlight that passes through window glass is visible light, and it is thought that if a certain amount of visible light could be blocked, considerable heat-shielding properties could be obtained. Furthermore, because conventional heat-shielding paints are colorless and transparent, it is difficult to distinguish between areas that have been coated and areas that have not, and it is very time-consuming to apply the paint evenly.

[0005] An object of the present invention is to provide a method for controlling the environment of an indoor space that can control the amount of sunlight transmitted through the room.

[0006] The present invention is an indoor space environment control method that controls the indoor environment of an indoor space by arranging a colored, light-transmitting, heat-shielding material in the form of a thin film at a desired position on a surface of a translucent transparent member facing an indoor space, on the exterior space side or the interior space side, through which sunlight passes when reaching the indoor space from the exterior space. The method controls the amount of sunlight that passes through the translucent transparent member, and is characterized in that it includes a thin film formation step of arranging the heat-shielding material in the form of a thin film at a predetermined position on the surface of the translucent transparent member facing the exterior space or the interior space, and by repeatedly carrying out the thin film formation step, a thick layer portion in which the heat-shielding material is arranged in a layered manner on the translucent transparent member, and a layered thin layer portion in which the heat-shielding material is arranged in the translucent transparent member thinner than the thick layer portion are formed.

[0007] The present invention also provides an indoor space environment control method for controlling the indoor environment of an indoor space by arranging a colored, light-transmitting, heat-shielding material in the form of a thin film at a desired position on a surface of a translucent transparent member facing an indoor space, on the exterior space side or the interior space side, through which sunlight passes when reaching the indoor space from the exterior space. The method controls the amount of sunlight that passes through the translucent transparent member, and is characterized in that the method includes a thin film formation step of arranging the heat-shielding material in the form of a thin film at a predetermined position on the surface of the translucent transparent member facing the exterior space or the interior space, and by repeatedly carrying out the thin film formation step, a thick layer portion in which the heat-shielding material is arranged in layers on the translucent transparent member, and a non-heat-shielding portion in which the heat-shielding material is not arranged on the translucent transparent member, are formed.

[0008] Here, the colored light-transmitting heat-shielding material of the present invention is one that is made of a colored material, or it does not refer to a transparent material but also includes one that is made of a material with a so-called cloudy color. That is, the colored light-transmitting heat-shielding material of the present invention hardly loses its transparency when it is simply provided very thinly on a light-transmitting transparent member, but as the film thickness of the entire heat-shielding material increases, its light transmittance decreases and, when it exceeds a certain limit, it becomes opaque to some or all of visible light.

[0009] In this configuration, the heat-shielding performance of the translucent transparent member is improved by the laminated thick layer portion in which the heat-shielding material is thickly arranged. Meanwhile, when attempting to view the interior of the indoor space from the exterior space side or the exterior space from the interior space side through the translucent transparent member, the area where the thick layer portion is arranged will have poor visibility, while the thin layer portion or the non-heat-shielding portion has relatively excellent visibility, ensuring both heat-shielding effect and visibility. That is, by appropriately determining the area ratio between the thick layer portion and the thin layer portion or the non-heat-shielding portion and the pattern (design), it is possible to ensure both desired heat-shielding performance and visibility. For example, by increasing or decreasing the area ratio of the thick layer portion, the amount of sunlight transmitted through the translucent transparent member can be appropriately controlled. Naturally, a unique design composed of the thick layer portion and the thin layer portion or the non-heat-shielding portion can impart significant design appeal. Furthermore, since the heat-shielding material of the present invention is colored as described above, when it is applied to a translucent member, it is easy to distinguish between areas that have been applied and areas that have not, making it easier to apply the heat-shielding material and allowing the person requesting the application to easily understand that the material has been applied.

[0010] The thick layer portion made of the heat-shielding material may have heat insulating properties.

[0011] Furthermore, the heat-shielding material may be a heat-shielding paint, and by repeatedly carrying out the thin film formation process, a thick layer portion in which the heat-shielding paint is applied to the translucent transparent member in a thick, layered manner, and a layered thin layer portion in which the heat-shielding paint is applied to the translucent transparent member in a thinner manner than the thick layer portion, may be formed, and the process may further include, between one thin film formation process and the next thin film formation process, a thin layer portion sealing member formation process in which the portion that will become the thin layer portion is covered with a thin layer portion sealing member, and a thin layer portion sealing member removal process in which, after the thin layer portion sealing member formation process, the thin layer portion sealing member is removed to turn the removed portion into a layered thin layer portion in which the heat-shielding paint is applied to the translucent transparent member in a thinner manner than the thick layer portion.

[0012] Furthermore, the heat-shielding material may be a heat-shielding paint, and by repeatedly carrying out the thin film formation process, a thick layer portion in which the heat-shielding paint is applied in a thick layer form to the translucent transparent member and a non-heat-shielding portion may be formed, and the method may further include a non-heat-shielding portion sealing member forming process before the thin film formation process, in which the portion that will become the non-heat-shielding portion is covered with a non-heat-shielding portion sealing member, and a non-heat-shielding portion sealing member removal process after the non-heat-shielding portion sealing member forming process, in which the non-heat-shielding portion sealing member is removed to make the removed portion a non-heat-shielding portion.

[0013] The present invention also provides an indoor space environment control method that controls the indoor environment of an indoor space by arranging a colored, light-transmitting, heat-shielding material in the form of a thin film at a desired position on a surface of a light-transmitting transparent member facing an indoor space, on the exterior space side or the interior space side, through which sunlight passes when reaching the indoor space from the exterior space, thereby controlling the amount of sunlight that passes through the light-transmitting transparent member, the indoor space environment control method comprising: a thin film formation step of arranging the heat-shielding material in the form of a thin film at a predetermined position on the surface of the light-transmitting transparent member facing the exterior space or the interior space; and a design material arrangement step of arranging a light-transmitting design material in the position where the heat-shielding material is arranged in the form of a thin film, following the thin film formation step.

[0014] In such a configuration, by placing a translucent decorative material on the translucent transparent member, not only can the amount of sunlight transmitted through be controlled, but the translucent transparent material can also be decorated to improve its appearance.

[0015] Furthermore, the present invention may include, following the decorative material arrangement step, a thin film re-forming step of arranging the heat shielding material again in a thin film form on the decorative material.

[0016] In this configuration, the decorative material can be protected by the heat-shielding material.

[0017] The present invention also provides an indoor space environment control method for controlling the indoor environment of an indoor space by arranging a colored, light-transmitting, heat-shielding material in the form of a thin film at a desired position on a surface of a light-transmitting transparent member facing an indoor space, on the exterior space side or the interior space side, through which sunlight passes when reaching the indoor space from the exterior space, thereby controlling the amount of sunlight that passes through the light-transmitting transparent member, the indoor space environment control method comprising a thin film formation step of arranging the heat-shielding material in the form of a thin film at a predetermined position on the surface of the light-transmitting transparent member facing the exterior space or the interior space, and characterized in that the heat-shielding material already contains a light-transmitting design material.

[0018] In such a configuration, the translucent design material contained in the heat-shielding material is arranged in the translucent transparent member, which not only controls the amount of sunlight that passes through, but also makes it possible to decorate the translucent transparent material to improve its appearance.

[0019] The indoor space environment control method of the present invention has the excellent effect of easily controlling the amount of sunlight transmitted.

[0021] The present invention will be described with reference to the following examples. The present invention is not limited to the examples shown below, and design changes are possible as needed. In addition, in the drawings, the thicknesses of the various components are depicted differently from the actual thicknesses in order to facilitate understanding of the present invention.

[0022] Example 1 In a specific indoor space β facing a translucent transparent member 10 composed of a translucent material such as window glass, sunlight can reach the indoor space β from an outdoor space α (outdoor space) through the translucent transparent member 10. The procedure for applying a colored, translucent heat-shielding coating material 20 (hereinafter simply referred to as the heat-shielding coating material 20) for heat insulation purposes to the surface of the translucent transparent member 10 facing the outdoor space α is described with reference to Figures 1 to 3. In particular, the present invention is characterized in that the translucent transparent member 10 has a single area to be heat-shielded, and some areas are coated with the heat-shielding coating material 20 and some are not. The heat-shielding coating material 20 is translucent yet opaque, and when applied to a certain thickness or greater, reduces the transmission of visible light. The heat-shielding coating material 20 also has thermal insulation properties. The colored, translucent heat-shielding coating material 20 of this example constitutes a colored, translucent heat-shielding material according to the present invention.

[0023] First, as shown in FIG. 1, on the surface of the translucent transparent member 10 facing the outdoor α side, the areas where the heat-shielding paint 20 is not to be applied are covered with a sealing member 30 for non-heat-shielding portions such as masking tape or a formwork (non-heat-shielding portion sealing member forming process).

[0024] Next, as shown in Fig. 2(a), the heat-shielding paint 20 is applied to the translucent transparent member 10 (thin film formation process). A sponge roller, a brush, or a trowel can be used to apply the heat-shielding paint 20, or other methods such as spray application can be appropriately proposed. Generally, the heat-shielding paint 20 is a suspension of fine particles mixed in a transparent solvent, and the particles are dispersed by stirring before use. In this case, the particles can be dispersed well by stirring using ultrasound.

[0025] Then, after the first application of the heat-shielding paint 20 is completed and the heat-shielding paint 20 has dried into a thin film (application and drying step), another coat of the heat-shielding paint 20 is applied on top of it as shown in Fig. 2(b). This is repeated until the heat-shielding paint 20 reaches a predetermined thickness as shown in Fig. 2(c).

[0026] When the heat-shielding paint 20 reaches a predetermined thickness and a laminated thick layer portion 50 is formed by applying the heat-shielding paint 20 to the translucent transparent member 10 to a predetermined thickness, the non-heat-shielding portion sealing member 30 is removed (non-heat-shielding portion sealing member removal step) as shown in Fig. 3. As a result, the thick layer portion 50 where the heat-shielding paint 20 is applied thickly and the non-heat-shielding portion 60 where the heat-shielding paint 20 is not applied are formed adjacent to each other in the translucent transparent member 10.

[0027] In the translucent transparent member 10 coated with the heat-shielding coating material 20, the thick layer portion 50 blocks not only ultraviolet and infrared rays but also visible light, thereby achieving an extremely high heat-shielding effect. Furthermore, the thick layer portion 50 also provides thermal insulation, allowing for optimal control of the indoor environment of the indoor space β. The non-heat-shielding portion 60 also ensures visibility through the translucent transparent material 10. The area ratio between the thick layer portion 50 and the non-heat-shielding portion 60 can be adjusted to change the thermal insulation performance and the thermal insulation performance, while ensuring appropriate visibility and appropriately controlling the indoor environment of the indoor space β. Furthermore, because the color intensity differs between the thick layer portion 50 and the non-heat-shielding portion 60 depending on their thicknesses, a desired design can be imparted to the translucent transparent member 10 by, for example, applying a regular coating pattern.

[0028] Example 2 The coating procedure in Example 2 will be described. As shown in Fig. 4(a), the heat-shielding paint 20 is repeatedly applied to the translucent transparent member 10 with the non-heat-shielding portion sealing member 30 attached, and as shown in Fig. 4(b), a portion of the area where the heat-shielding paint 20 has been applied is further covered with the thin layer portion sealing member 31 (thin layer portion sealing member forming step). Thereafter, the heat-shielding paint 20 is further applied to areas not covered with the non-heat-shielding portion sealing member 30 and the thin layer portion sealing member 31.

[0029] Then, after the process of applying the heat-shielding paint 20 is completed, the non-heat-shielding portion sealing member 30 and the thin layer portion sealing member 31 are removed as shown in Figure 5 (non-heat-shielding portion sealing member removal process and thin layer portion sealing member removal process).

[0030] 5, it is possible to form not only a thick layer portion 50 that blocks visible light and a non-heat-shielding portion 60 that transmits visible light almost completely, but also a thin layer portion 70 that is relatively transparent to visible light compared to the thick layer portion 50. This allows the formation of three portions with different appearances, thereby further imparting design features to the translucent member 10. Naturally, the thick layer portion 50 and the thin layer portion 70 can also provide heat insulating performance.

[0031] Of course, by applying the heat-shielding coating material 20 to the translucent transparent member 10, it is possible to achieve the effect of appropriately controlling the amount of sunlight transmitted through the translucent transparent member 10.

[0032] Example 3 The application procedure in Example 3 will be described. As shown in Figure 6(b), sealing members 110 for non-heat-shielding portions are attached vertically at predetermined intervals to the surface of the light-transmitting transparent member 100 on the outdoor α side shown in Figure 6(a). Then, the heat-shielding paint 20 is applied to the surface (entire area) of the light-transmitting transparent member 100 on the outdoor α side.

[0033] After the application and drying of the heat-shielding paint 20 is completed, the sealing member 110 for the non-heat-shielding portion is removed, and as shown in Figure 7, a translucent transparent member 100 with a vertical stripe pattern in which thick portions 120 and non-heat-shielding portions 130 appear alternately like a zebra pattern can be obtained.

[0034] In this case, the amount of sunlight transmitted through the translucent transparent member 100 can be appropriately controlled by adjusting the vertical length, horizontal width, or spacing of the thick layer portion 120 and the non-heat-shielding portion 130 .

[0035] Here, the heat-shielding paint 20 may be further applied to the translucent transparent member 100 to make all or part of the non-heat-shielding portion 130 a thin layer portion.

[0036] Example 4 The coating procedure in Example 4 will be described. As shown in Fig. 8(a), a sealing member 160 for non-heat-shielding portions, which functions as a thin formwork sheet like the joints in a brick wall, is attached to a translucent transparent member 150. Then, the heat-shielding paint 20 is applied to the translucent transparent member 150.

[0037] After the application and drying of the heat-shielding paint 20 is completed, the sealing member 160 for the non-heat-shielding portion, which functions as a thin formwork sheet, is removed, thereby leaving the translucent transparent member 150 colored like a brick pattern by the thick layer portion 170 and the non-heat-shielding portion 180, as shown in Figure 8(b). Note that the state of the interior space β facing the translucent transparent member 150 can be seen through the non-heat-shielding portion 180.

[0038] In this case as well, the amount of sunlight transmitted through the translucent transparent member 150 can be appropriately controlled by adjusting the vertical length, horizontal width, or spacing of the thick layer portion 170 and the non-heat-shielding portion 180 .

[0039] In the above embodiment, the thick layer portion 50 and the thin layer portion 70 do not need to have a uniform thickness, and may have a partially increased or decreased thickness. In addition, for the purpose of adding design, for example, unevenness may be intentionally provided when the heat-shielding coating material 20 is applied.

[0040] The translucent transparent member 10 also includes window glass (including wired glass) installed in rooms, factories, and warehouses, and transparent resin members used in roofs and eaves of skylights, carports, etc.

[0041] Furthermore, a material for preventing cracking of glass or the like may be added in advance to the heat-shielding coating material 20. This configuration has the advantage that a new function can be added to the translucent transparent member 10 by applying the heat-shielding coating material 20, eliminating the need to replace the entire translucent transparent member with a new one.

[0042] Furthermore, when the translucent transparent member 10 is made of window glass, for example, it may be subjected to blasting or grinding in advance.

[0043] The thick layer portion 50 and the thin layer portion 70 may be formed by a method in which the heat-shielding paint 20 is poured and spread on the outdoor α-side surface of the translucent member 10, such as a window glass, which has been removed from the window frame and laid flat, thereby forming a thin film, which is then dried.

[0044] Furthermore, designs consisting of the thick layer portion 50 and the thin layer portion 70 formed on the translucent transparent member 10 are proposed to have horizontal stripes, vertical stripes, a lattice pattern, or a brick wall pattern, and of course other patterns are also acceptable.

[0045] The provision of a thin film of heat-shielding material includes applying a thin film of heat-shielding paint and providing a thin heat-shielding sheet.

[0046] [Example 5] The coating procedure in Example 5 will be described below. As shown in Fig. 9, the heat-shielding paint 20 is applied to the translucent member 200 to form a thin film (thin film forming step).

[0047] Then, the heat-shielding paint 20 is again applied on top of the heat-shielding paint 20 that has been arranged in a thin film form, and Japanese paper 210 as a translucent design material is attached to a predetermined location on the heat-shielding paint 20 (design material arrangement process). Note that the heat-shielding paint 20 acts as an adhesive component and can be attached well to the Japanese paper 210, but if the Japanese paper 210 is arranged on the heat-shielding paint 20 before the heat-shielding paint 20 dries, the Japanese paper 210 is likely to be attached to the heat-shielding paint 20.

[0048] In this configuration, by disposing the heat-shielding paint 20 and Japanese paper 210 on the translucent transparent member 200, the amount of sunlight transmitted through the translucent transparent member 200 can be appropriately controlled, and the translucent transparent member 200 can also be given a decorative design.

[0049] Here, examples of translucent design materials include, in addition to Japanese paper, artificial materials such as cloth, natural materials such as seashells, and metal foils such as gold and silver foils. The design materials may be used as they are, or may be formed into a predetermined shape.

[0050] The thin film forming process may be performed once, or may be repeated multiple times until the thin film of the heat-shielding paint 20 reaches a predetermined thickness. Furthermore, after the Japanese paper 210 is attached, the heat-shielding paint 20 may be further applied repeatedly.

[0051] Example 6 The coating procedure in Example 6 will be described below. As shown in Fig. 10, the heat-shielding paint 20 is applied to the translucent member 220 to form a thin film (thin film forming step).

[0052] Next, Japanese paper 210 is placed as a translucent design material in the predetermined area where the heat-shielding paint 20 has been placed (design material placement process). At the same time, the heat-shielding paint 20 is again applied on top of the Japanese paper 210 to form a thin film of the heat-shielding paint 20 (thin film re-forming process), and the Japanese paper 210 is attached onto the heat-shielding transparent member 220.

[0053] With this configuration, the Japanese paper 210 is placed on the translucent transparent member 220 by the heat-shielding coating material 20 that is applied in the thin film reforming process.

[0054] By disposing the heat-shielding paint 20 and the Japanese paper 210 on the translucent transparent member 220, the amount of sunlight transmitted through the translucent transparent member 220 can be appropriately controlled, and the translucent transparent member 220 can also be given a decorative design.

[0055] The thin film forming step may be performed once, or may be repeated multiple times until the heat-shielding coating material 20 disposed in a thin film form reaches a predetermined thickness.

[0056] Example 7 The coating procedure in Example 7 will be described below. As shown in Fig. 11, the heat-shielding coating material 20 is applied once to the light-transmitting transparent member 230, and the heat-shielding coating material 20 is arranged in the form of a thin film.

[0057] Next, the heat-shielding paint 20 is applied again to a predetermined portion of the area where the heat-shielding paint 20 has been applied (thin film forming step). The heat-shielding paint 20 contains gold foil 240 as a translucent design material.

[0058] This allows the gold foil 240 to be placed at a predetermined location on the translucent transparent member 230, making it possible to appropriately control the amount of sunlight transmitted through the translucent transparent member 230 and also to add a decorative touch to the translucent transparent member 230.

[0059] The gold foil 240 may be disposed only on a predetermined portion of the translucent transparent member 230, or may be disposed on the entire surface.

[0060] The thin film forming step may be performed once, or may be repeated multiple times until the heat-shielding coating material 20 disposed in a thin film form reaches a predetermined thickness.

[0061] Next, a method for preventing overlapping of adjacent coated areas in the coating procedure of the heat-shielding paint 20 will be described. For example, in each of Examples 1 to 7 described above, when the heat-shielding paint 20 is applied to the translucent transparent member 320 using a sponge roller or a brush, the heat-shielding paint may be applied in duplicate at both ends of the sponge roller or the brush. In the present invention, the cloudy-colored heat-shielding paint 20 is applied to the transparent translucent transparent member 320, and this causes uneven coating in the overlapping areas, resulting in an unintended, dirty color scheme or design.

[0062] Therefore, as shown in Figure 12(a), in order to prevent unevenness in the overlapping of the heat-shielding paint 20 that has already been applied, sealing members 310, 310 are first placed at an interval of width L2 based on the edge of the heat-shielding paint 20 that has already been applied. Then, as shown in Figure 12(b), the heat-shielding paint 20 is applied to the uncoated portions using a sponge roller 300 with a width L1 that is wider than width L2. Then, by repeatedly performing this procedure, it becomes possible to apply adjacent layers of the heat-shielding paint 20 sequentially to the translucent transparent member 320 without causing unevenness in the overlapping of the paint, as shown in Figure 12(c) and Figures 13(d) to (g).

[0063] In each of the above-described embodiments, when the heat-shielding coating 20 is applied in the form of a thin film, it may be applied not only to the outdoor α side of the translucent member but also to the indoor space β side.
