Description

According to the present invention, from the theory described below, as shown in FIG. 3A, a sheet (resin sheet) is set in a roll shape and is drawn out and provided on the window frame as shown in FIG. By feeding the sheet along the rail upper groove, the window frame and the entire window glass surface are covered to prevent condensation. The principle of opening and closing is the same as in FIGS. 3-F, 3-G, and 3-I. However, in the case of FIG. 3-F, the sheet (resin sheet) is rolled and placed in the hangar. The wound sheet (resin sheet) is opened and closed in the left-right direction, and in the case of FIG. At that time, in the case of a double door, a guide is provided at the center (FIG. 3-H) to prevent distortion due to sheet sagging or wind pressure. FIG. 3I is a diagram set in the upward direction from the downward direction. In any case, the effect of preventing condensation has not changed. However, it is affected by rain, sand, dust, dust, etc., and unlike other open / close types, it is finished with a rainproof, sandproof, dustproof, and dustproof packing. If the window is made of a single piece of glass, the indoor surface temperature will be extremely low compared to other parts. In the case shown in FIG. 4, when the room temperature on the indoor side of A and C when the room temperature is 20 ° C. and the outside air is 0 ° C. is obtained by differentiation, A is 11.3 ° C. , C is 7.01 ° C. For this reason, when the relative humidity of the indoor air reaches 43%, condensation occurs on the glass surface. On the other hand, on the concrete wall, condensation does not occur unless it becomes 57%. If a 25 mm heat insulating material (thermal conductivity 0.03 kcal / mh ° C.) is added to the concrete wall surface, the surface temperature becomes 17.8 ° C., so 87% is the dew point. In this way, in the case of a single glass, the surface temperature on the indoor side is too low, and condensation occurs most quickly. Since glass has a high thermal conductivity, the occurrence of condensation does not change depending on its thickness, whether it is 3 mm or 6 mm. Further, when the surface temperature of the glass is low, the air touching the glass is cooled to increase the density, and the downward flow is promoted. At the same time, the air humidity touching the glass is lower than that of other general air. Then, naturally, the surface temperature of glass will become low and dew condensation will be promoted. The window frame part of B becomes a thermal bridge of aluminum, and this part also becomes extremely low in humidity like the glass surface. In the era when wood frames were used in the past, the thermal conductivity of wood was much less resistant to heat than aluminum and iron, so the interior surface did not become extremely cold, but the thermal conductivity Is wood 0.11-0.15 kcal / mh ° C, plastic 0.15-0.25 kcal / mh ° C, iron 38-47 kcal / mh ° C, aluminum 180 kcal / mh ° C, and aluminum is a material that passes heat 1200 times that of wood Therefore, it creates a strong cooling and heating bridge. Therefore, in the case of housing design, it is desirable to provide a finishing frame made of wood or plastic inside the aluminum window. In the case of a double window with a metal sash, it is better to cut the edges of the outer frame and the inner frame and sandwich the insulation. For the purpose of the present invention, as shown in FIG. 3B, the glass frame and the glass surface are covered with a transparent sheet, and at the same time, any of opaque and red, blue, white, yellow, green and other multicolor sheets are set in the hangar. By satisfying some condensation prevention and making it opaque, crime prevention (the sheet can be set freely depending on the purpose, thick or thin, but the limit is that the sheet can be rolled in), the inside of the room is not visible from the outside You can also In the case of dirt breakage, the cutting cutter part can cut (Figure 3-C), and the sheet stored in the hangar is pulled out from the cut part, and a frame is set on the sheet (Figure 3-D). Is also very simple.

Conventionally, a raw material (methacrylic resin (PMMA), polycarbonate (PC), polystyrene (PS), polyvinyl chloride (PVC), etc.) that can store (round) the window frame and the entire window glass is a sheet (rounded thickness 0. There was no window glass, window frame or the like (sash, wooden, resin coating, etc.) including a window frame that covered and prevented dew condensation. Moreover, it is excellent in daylighting (transparency). Conventional window frames are generally sliding doors (some resins have more transparency than glass). Double glass and pair glass are generally sliding doors.

In current houses and buildings, many windowpanes are attached from the viewpoint of daylighting, but these are contradictory to heat insulation. In order to prevent heat from flowing in and out of this, use a plate glass or film with a metal film that suppresses radiant heat called Low-E (Low-Emission) glass, or 6 to 12 mm of double-layered glass called multi-layer glass. There are also used materials that have heat insulation properties by filling the gaps with dry air or argon gas, creating a vacuum layer, or making double sashes. In some parts of Europe, triple-layer glass called triple glass is filled with dry air and argon gas, and then Low-E glass is attached. In addition, since a sash made of aluminum is very easy to conduct heat, a resin or wooden sash, or a composite sash having a resin or wooden interior is generally used. In the past, wooden sashes were banned because they burned, but aluminum sashes were easily melted, but wooden sashes were screamed that they would not burn up to the inside. The law was amended that the materials would not be restricted if tested and shown. However, since the construction cost is higher than that of general window glass, it is not popular. As described above, the high cost of advanced technology, the above-mentioned high cost of construction technology, the difficulty of maintenance, management and repair (maintenance), and the weight increase, resulting in large construction. There was a difficult point. The present invention has been made to solve this problem.

As shown in FIG. 1 and FIG. By covering the window frame and the entire window surface, there is no direct contact between the window frame and the window surface, and warm heat passing through the window surface is prevented by this surface. By making use of the heat, it was decided to prevent rapid temperature (room and window frame, window surface) drop by using the heat that is sent from the next room. Further, when taking outside air such as daytime, a sheet (made of any one of PMMA, PC, PS, PVC, etc.) can be surrounded and stored in the storage. In addition, in windows on the veranda, etc., it was designed not to obstruct the loading and unloading of luggage.

There is no need to replace the window frame and window glass that are currently in use, the construction is simple and inexpensive, and the window surface (made of any one of PMMA, PC, PS, PVC, etc.) is dirty, If it breaks, it is a roll-in type, so it is convenient to pull it out. Today, when energy consumption has increased rapidly, air-conditioning efficiency is good, energy costs can be reduced, and global warming can be prevented. Hereinafter, embodiments of the present invention will be described. (A) A hangar in which a sheet (made of any one of PMMA, PC, PS, PVC, etc.) is first wound is attached with a window frame and a window surface. Attach the hangar to the upper wall.
From there, pull out the sheet, pass the sheet through the groove through which the sheet attached to the frame for building the heat storage layer on the window frame surface, and lower it to the bottom of the frame (at the bottom part of the sheet, Stop with a stopper. This completes.
(B) When winding up, release the stopper and place it in the take-up hangar.

Claims (1)

As shown in Fig. 3-A, the window frame and the transparent sheet covering the window surface (metal resin PMMA polycarbonate PC, polyethylene PS, etc.) are rolled into the hangar, set in several pieces, and if necessary, from the hangar By lowering the sheet, it has the same purpose as the window glass, and at the same time it doubles the triple triple quadruple to enhance the passing heat step by step, thereby increasing the window frame and window glass sheet of the dew condensation prevention device. It becomes. In addition, by processing the materials of these sheets, or by processing them, Fig. 3-B, Fig. 3-E-5 insect netting sheet, Fig. 3-B infrared cut sheet or ultraviolet cut sheet, red transparent, Blue transparent, yellow transparent, green transparent, stained glass-like coloring, landscapes by photography, painting printing sheets, etc. can be wound and set in roll form. At that time, it is possible to process the red, blue, yellow, green, stained glass-like colors, landscapes by photography, painting printing, etc. described above on the infrared cut sheet or ultraviolet cut sheet, and roll and set in a roll shape. . In other words, it can be installed cheaper than double sash (glass window) devices or paired glass (multi-layer glass window), etc., and can be easily attached to the current window. Yes, they are more effective against condensation than those glasses. Condensation generation is very effective in the double glass, pair glass, and the like that are currently on the market or are being constructed. As for condensation, for example, in winter, when the outdoor temperature is 5 ° C., there is a room where the internal temperature must be kept at 30 ° C. When the window glass in this room is 4 mm, how much temperature (heat) per unit area escapes to the outside air through the window glass, and what is the temperature inside and outside the window glass at this time However, the thermal conductivity of the glass is 0.76 w / (m, k), and the thermal conductivity of the inside and outside of the glass is 10 and 50 w / (m ² , k), respectively.
The heat transfer rate k is

Therefore, in a steady state, the heat flux q passing through the unit area (1 m ² ) of glass in unit time (1 s) is q = k (θ _f1 −θ _f2 ) = 7.98 (30−5) = 199.5 W / m ²
If the temperature inside the glass is θ _w1 , the heat passing amount q is also equal to the heat transfer amount inside the glass.
Therefore,
q = h ₁ (θ _f1 −θ _w2 ) = 10 (30−θ _w1 ) = 199.5 ∴θ _w1 = 10.1 ° C.
Similarly, if the temperature outside the glass is θ _w2 ,
q = h ₂ (θ _w2 −θ _f2 ) = 50 (θ _w2 −5) = 199.5 ∴θ _w2 = 9.0 ° C.
