An energy saving type double window structure is formed by installing window frames(101,102) fixed with glass windows(103,104) to a window sash(180), installing a blind(120) to a space(B) between the glass windows of a double window, and installing doors(130,140) to openings(101a,101b) formed on the upper and lower parts of the outer window, and used for preventing the transfer of heat from the space to the outside by convection by closing the doors of the upper and lower openings and letting sunlight in by lifting up the blind in the wintertime, and cutting off sunlight by shading with the blind and letting the outside air in the lower opening and releasing the heated inside air to the outside through the upper opening by convection if the air temperature in the space between the blind and the glass window rises by opening the doors of the upper and lower openings in the summertime.

Description

Energy saving double window structure {Double window}

The present invention relates to a double-window structure, and more particularly, to an energy-saving double-window structure that can reduce the cooling energy of the room by discharging the heat by solar radiation that can be generated in the space between the double window structure.

Most of the buildings are equipped with windows for ventilation and lighting. Recently, when designing windows in buildings, the trend is to make double windows for the purpose of insulation and sound insulation.

1 shows the configuration of a conventional double glazing. As shown, the window frame 2, which is provided with the glass windows 3 and 4, respectively, is provided at a predetermined distance in double. In such a structure, there is a space (A) between the windows and the sound insulation and heat insulation effect is increased by this space, the structures are well known and actually implemented.

However, in the conventional double-window structure, the temperature between the windows is very high due to daylight when the space between the windows is low, and when the air conditioner is operated as in summer, the heat of the space where the temperature rises is exchanged with the inside through the inner glass window. Raise the temperature of the room.

In order to improve this point, blinds are installed in the space between the double windows, and the opening and closing of an external ventilation window or an exhaust duct is installed at the top of the windows to develop a technology for discharging the air in the space between the double windows. In Korea, research on energy saving effect is underway by installing additional ventilation windows on the upper and lower sides.

However, in the case of installing the ventilation windows on the upper and lower sides, there is a restriction that the external shape is fixed to three windows. In addition, there is a problem in that the construction cost increases compared to the existing one window is installed due to the addition of a new construction that is installed two ventilation windows.

In addition, the prior art has a structure made to divide the window of the outer surface into three parts and the upper and lower parts can be opened and closed, but it is very difficult to divide into three parts at the time of manufacture, there is a problem in that excessive cost in terms of cost.

The present invention has been made to solve the above problems of the prior art, the purpose of reducing the cooling energy by forming a hole in the upper and lower window frame so that the heat accumulated in the space between the double window is arranged to the outside by convection. have.

In addition, by installing ventilation windows on the upper and lower sides of the exterior, energy savings that can reduce the process and construction costs by not changing the appearance form compared to the existing technology that the appearance form is fixed regardless of the original design. Its secondary purpose is to provide a double glazed structure.

Energy-saving double glazing structure according to the present invention in the double glazing structure in which the glass window is installed more than double so as to have a certain space between the outer wall of the building,

One or more openings are respectively provided at the upper or lower portion of the window frame or the window frame of the glass window which is installed on the outermost side of the glass window, such that the inner rows of the space with the blinds provided between the glass windows are arranged by convection.

Here, blinds are installed in the spaces between the windows.

In addition, the opening and closing the door to be installed in the opening.

As such, the energy-saving double window structure according to the present invention provides an effect of reducing energy by lowering the air temperature in the space between the double windows by installing openings at predetermined intervals above and below the window frame.

A cross sectional view of a double glazing structure according to an embodiment, showing the operation of the door.

A first embodiment of the double glazing structure according to the invention is shown in FIGS. 2 and 3. As shown, the window frame 12 to which the glass window 13 is fixed is installed on the window frame 15 when viewed from the outside of the double windows 13 and 14 installed on the outer wall 10. Referring to FIG. 3, a blind 20 is installed between the two windows 13 and 14, and the openings 11a and 11b are formed in upper and lower portions of the outer window frame 11. The blind 20 serves to block sunlight coming into the room through the outer glass window 14. Therefore, convection occurs due to the temperature difference of air in the space between the inner and outer glass windows 13 and 14. As shown by arrows in FIG. 3, when the air between the outer glass window 14 and the blind 20 receives heat and the temperature rises, convection is performed through the upper opening 11b.

Without the openings 11a and 11b, in summer, the temperature of the space between the two windows 13 and 14 rises much higher than the outside air due to the heat transfer of sunlight, and thus heat transfers to the inside by heat exchange with the inner window 13. This will put more load on the summer air conditioner that normally drives the air conditioner will reduce the energy efficiency. However, as shown in FIG. 3, when the openings 11a and 11b are formed and the air temperature between the inner and outer glass windows 13 and 14 rises higher than the outside air temperature in summer, the heat in the space therebetween is caused by convection. Arranged to lower the temperature. Therefore, the load on the air conditioner is reduced.

4 to 5 show a second embodiment of the double glazing structure according to the present invention. As shown, the window frames 101 and 102 are fixed to the window frame 180 to which the glass windows 103 and 104 are fixed. The double window is composed of double glass windows 103 and 104 on the inside and the outside, and a space B is formed between the glass windows 103 and 104, and a blind 120 is provided in the space B. Openings 101a and 101b are formed in the upper and lower portions of the outer window frame 101, and doors 130 and 140 are provided in the openings 101a and 101b, respectively.

In the non-cooling period, such as winter, the doors 130 and 140 of the upper and lower openings 101a and 101b are closed to block the heat inside the space B from being arranged outside by convection. To raise the blinds 120 so as to receive the maximum incoming sunlight.

As in the first embodiment, during the summer when the indoor cooling load is increased by the sun, the blind 120 is lowered to block sunlight from entering the room, and the doors 130 and 140 of the upper and lower openings 101a and 101b are opened. As a result, when the air temperature of the space B between the blind 120 and the window 104 rises, outside air flows into the lower opening 101a as shown by an arrow in FIG. Is discharged to the outside through the upper opening 101b.

In the embodiments of the present invention, only the case where the glass window is installed in a double, but even if it is composed of three or more of the multiple glass window if the opening is formed in the upper and lower windows so that air can be circulated in the window frame or window frame of the outer glass window The effect can be obtained.
