Description

Insulating and blinding system window consisted of pair glass using beads}

The present invention relates to a double-window insulation system window using beads, and more specifically, a spherical shape having a small diameter such as styrofoam or cork, such as synthetic resin, wood-based and silica gel insulation, which has a low thermal conductivity. After manufacturing the in beads, and filling the appropriate amount of beads into the bead housing, which is the inner space of the lower frame constituting the window frame, the bead is doubled from the lower frame bead storage unit by using a blower installed in the inner window frame space. The present invention relates to a double-window insulation system window using a bead that improves heat insulation and sunshade and aesthetics by floating in a space between two pieces of glass facing each other.

In buildings, windows are an essential component that isolates the natural and indoor environment, acts as a supply of sunlight and fresh outside air, and gives people a sense of view and openness, but heat loss and heat absorption through the window are: As shown in Table 1, the heat transmission rate is ten to ten times higher than that of the insulating wall.

Therefore, the windows of the building will increase the maintenance cost of the building by causing excessive load increase of the air conditioner for the air conditioning inside the building. Therefore, to reduce the energy used in the building, heat loss and heat absorption through the window must be minimized. shall.

However, as shown in Table 1, the window has a lot of heat loss that can not be compared to the wall, but the window material must satisfy the prerequisite that the window should have adequate transparency so that the exterior can be seen while ensuring the appropriate level of strength. However, there is a restriction that a transparent or translucent or unidirectional transparent glass or the like must be used.

Therefore, low-emission coated glass, low-emissive film insert glass, gas-encapsulated glass, vacuum window, transmittance control glass, transparent insulating material injection glass, multilayer glass, etc. have been developed to improve the thermal insulation performance of the window. Special manufacturing technology is required and the price is rising is difficult to use universally.

The gas encapsulated glass and the vacuum window are the most representative ones of the glass to which the heat insulating performance is given, and these are double glazings in which two sheets of glass are laminated. There is a kind.

The simplest double glazing is simply the joining of two pieces of glass so that a certain gap is formed between the opposing surfaces of both glasses, commonly called pair glass. The pair glass retained the air layer remaining in the space secured between the two glasses for the first time, and the insulation performance and noise blocking performance were better to some extent than the single window, but the insulation performance was inevitably due to the air layer existing between the two glasses. Lowers. That is, heat transfer loss by the air layer cannot be prevented.

In order to compensate for the disadvantage of the double glazing, injecting a gas such as argon or krypton having low thermal conductivity into the space between two glass sheets facing each other has a gas filled double glazing, but this also has a limitation in reducing heat loss.

Therefore, a vacuum double glazing has been developed in which a vacuum state with a very small thermal conductivity is formed in the space between the glasses, wherein the vacuum formed in the space between the glasses has a level of 10 ^-6 torr, and gas or air remaining in the space between the glasses of the double glazing. The heat loss caused by thermal convection and conduction can be almost completely prevented.

However, the double window filled with the inert gas or the vacuum is expensive as described above, especially in the case of the vacuum window is difficult to use universally because the vacuum forming operation is very difficult technology.

In addition, even if the thermal insulation effect is obtained by the above-mentioned double windows, a separate curtain or blinder is necessary to prevent invasion of solar heat, which requires inconvenience of additional installation of solar heat shielding prevention equipment. The heat radiation shielding rate of the four heat shield facilities is shown in Table 2.

In addition to the limitations of the thermal insulation performance of the various double windows described above, another disadvantage is that the insulation and solar heat shielding method by gas encapsulation, transparent insulation material or other treatment is inevitable due to the aging change of the glass by the external environment such as sunlight. In addition, in the case of a vacuum window, it is difficult to manufacture a large window, and as described above, it is difficult to attain 70% or more of solar radiation shielding rate by the window itself, unless additional facilities are provided.

It is an object of the present invention to provide a double-window insulation system window that can be manufactured without a special manufacturing technology and not only retains thermal insulation performance and solar heat shielding function, but also obtains aesthetical decorative effect.

In addition, to provide a window system that can minimize the deterioration of thermal insulation performance and thermal radiation shielding function due to the secular variation inevitably over time.

The object of the present invention is a double window composed of two sheets of glass facing each other at a predetermined distance from each other, and the inner space is fixed to the peripheral portion of the double window is in communication with the inner space formed between the two sheets of glass to form an air flow path It is achieved by the provided window frame, hard bead filled in the bead receiving portion of the lower frame constituting the window frame, and a blower provided inside one side frame.

The window system of the double insulation window structure using the bead of the present invention, the air is blown by a blower installed inside the one side frame, the bead is filled in the bead housing portion which is the inner space of the lower frame of the window frame to fix and support the double window The technical feature is that the beads are suspended in the inner space between the two glasses to increase the insulation performance of the windows and at the same time obtain the direct light shielding effect.

And, by adjusting the blowing amount of the blower is a structure that can adjust the height of the beads floating in the space between the two pieces of glass facing each other.

At this time, the beads constituting the insulation system window is made of a synthetic resin foam such as EPS styrofoam or rigid urethane foam, wood such as cork, or a very light and small heat transfer coefficient such as transparent or semi-transparent silica gel insulation, 5 mm or less in diameter As a spherical form, it is colored or coated with a fluorescent material or the like as necessary, and the beads are suspended by blowing air to obtain adiabatic, direct light shielding and decorative effects.

In addition, the size of the beads having a diameter of 5 mm or less not only increases the internal volume of the lower frame required for filling the beads when the beads exceed 5 mm, but also increases the gap between the beads floating in the space between the glasses. This is because the solar heat shielding efficiency is reduced.

The above object and technical configuration of the double-window insulation system window using the bead of the present invention, and a description of the effect thereof, will be clearly understood by the following description with reference to the drawings showing a preferred embodiment of the present invention. will be.

1 to 3 illustrate a front view of an embodiment of the insulation system window and a cross-sectional view taken along line A-A of FIG. 1 and line B-B of FIG. 2.

As shown, the double-window insulation system window (1) using the beads of the present invention are two pieces of glass 15 facing each other and spaced apart from each other, a square frame (2) to which the glass is fixed, and a lower frame ( 11) Beads 12 filled therein, a blower 14 mounted inside one side frame 13 to float the beads 12, and a bead blocking film 19 provided inside the upper and lower frames ( 20).

In addition, the beads 12 filled in the inner space of the lower frame 11 have an inner space S formed between the two sheets of glass 15 by the air blown by the blower 14 installed in the one side frame 13. To be floated).

At this time, by adjusting the blowing amount of the air supplied from the blower 14 with the blower on / off and the blowing amount control switch 22 attached to the outer surface of the window frame 2 (height) D) can be adjusted and the upper and lower frame inner space (S ') (S' ") to prevent the floating beads from entering the lower portion of the inner frame (S ') and lower frame (S'") of the upper frame. The upper and lower bead blocking films 19 and 20 provided with air holes smaller than the diameter of the bead are provided in each lower part.

In the window system of the present invention, the interior space of the window frame 2, which serves as a flow path of air, consists of three parts among the four parts of the upper, lower, and two side frames 18, 11, 13, and 21.

That is, the inner space S '(S' ") of the upper and lower frames 18 and 11 and the inner space S" of the one side frame 13 are communicated with each other so that air can be circulated to blow air. Will form a flow path.

However, the other side frame 21 has a structure in which the three frames 11, 13 and 18 are not blocked and communicate with each other, and the air blown from the blower 14 is the one side frame internal space S. ") → the lower frame inner space (S ') → the inner space (S) between the double window → the upper frame inner space (S') is repeated to be re-absorbed to the blower.

At this time, the heat transmission rate and the solar heat shielding rate of the windows of the embodiment of the present invention is shown in Table 3.

As can be seen in Table 3, the heat insulation performance of the heat insulation system window of one embodiment of the present invention is somewhat less than that of foreign gas-sealed glass, but considering the manufacturing cost and manufacturing technology of the gas-sealed glass, the application of the window system of the present invention is more reasonable. In addition, if the flow of air circulating in the beads and the frame constituting the window system of the present invention is properly controlled, it is possible to improve the heat permeation rate and solar heat shielding rate.

As described above, the thermal insulation structure of the windows and doors of the present invention can reduce the production cost of the windows and windows by applying a relatively easy manufacturing technology compared to other technologies, such as vacuum windows, gas-filled windows or transmittance control glass windows. In addition, the use of common materials and simple basic principles allow various flexibility in the design of the window, which can be immediately applied to various construction sites.

In addition, although various thermal insulation layers of the related art have excellent thermal insulation performance, a low shielding rate of solar radiation is required, but a separate shielding device such as a blind is required, but the thermal insulation structure of the present invention possesses excellent shielding rate as well as a decorative effect. As a result, it is expected that the effect of functional windows and doors that can replace the function of the insulation curtain and the insulation shutters.
