According to the energy-saving window system according to the present invention, by improving the configuration of the surface contacting the glazing unit (Frame) and the frame of the window or curtain wall system to lower the heat transmission rate and improve the dew condensation resistance.

1 is a view schematically showing an energy saving window system according to the present invention.

The above objects, features and other advantages of the present invention will become more apparent by describing the preferred embodiments of the present invention in detail with reference to the accompanying drawings.

Hereinafter, an energy saving window system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Energy-saving window system according to the present invention is an energy-saving window system comprising a frame and a window frame portion installed on the frame, wherein the window frame portion is characterized in that the insulating film of a polymer material is attached to at least one surface in contact with the frame.

Referring to FIG. 1, when the energy saving window system according to the present invention is in contact with a wall or floor of a building, the window frame 120 is fixed to the surface 110, and the window frame 130 is attached to the frame 120. When the installation is provided so that the insertion and insertion is fixed, it can be seen that the heat insulating film 140 is attached to the window frame portion 130.

Here, the method of attaching the heat insulation film 140 may use the attachment by a conventional binder, as well as the adhesion using the shrinkage force of the film itself, and the adhesion that is pressed in a state of applying heat.

In addition, the heat insulating film 140 in Figure 1 the window frame portion 130 is provided on all three surfaces in contact with the frame, but is not limited to this, also carried out in the form attached to only one or two sides. can do.

The window frame part may be formed of a plate material in which each solar cell is laminated or laminated, as well as a double glass window, which is a glass material having a hollow layer in the center.

In the case of using the solar cell can be used for heating and cooling the building by using the electrical energy generated by the solar energy.

On the other hand, the insulating film may be provided with a thickness of 0.01 to 0.1 ratio of the window frame section cross-sectional width (Tk), if the ratio is less than 0.01, not only may be damaged when the window frame 130 is inserted, If the effect is negligible, on the contrary, if it exceeds 0.1, the heat shielding effect may be beneficial, but it may be a cost increase factor of the insulation film.

In addition, the insulation film may have an area strain of 0.1 to 10% after being attached to the window frame part. If the insulation film is less than 0.1, the dimensional stability may be very excellent, but it may be difficult to secure adhesion. If the percentage is exceeded, the dimensional stability may be reduced, causing bending or tearing, which may adversely affect the heat shielding function.

In addition, the insulation film may be more than 2N / ㎜ adhesion force after being attached to the window frame portion, if out of this range, the stress caused by repeated contraction or expansion by air pressure or temperature difference in summer and winter It is difficult to withstand and may cause lifting.

Here, although the upper limit of the adhesive force is not specifically mentioned, it may be 20 N / mm or less, this setting is difficult to ensure the durability of the adhesive force described above due to deterioration of the insulating film.

On the other hand, the polymer may be at least one selected from the group consisting of ethylene norbornene copolymer, polymethylenepentene, polycarbon terephthalate and polyphenylene sulfide, or the ethylene norbornene copolymer, polymethylenepentene, polycarbon tere At least one selected from the group consisting of phthalates and polyphenylene sulfides It is possible to use a mixture in a weight ratio of 1: 9 to 5: 5, and when such a material is made of a heat insulating film with a predetermined thickness, the thermal conductivity is low, so that the thermal permeability of the window can be lowered and condensation resistance can be secured. The weight ratio is to secure adhesiveness and dimensional stability in addition to securing insulation / heat shielding, if less than 1: 9, the dimensional stability can be reduced due to the seasonal climate after construction, on the contrary 5: 5 If exceeded, there may be a problem of delamination during or after the insulation film manufacturing process.

On the other hand, a functional composite layer made of a modified polyolefin resin, an unstretched polypropylene resin, an ethylene propylene copolymer, an ethylene propylene eotactic block copolymer or an ethylene propylene syndiotactic block copolymer on at least one surface of the insulating film and the frame. It may be further provided, the functional composite layer not only serves to prevent the thermal insulation film 140 is damaged when the window frame portion 130 is inserted, and increases the blocking heat effect.

In addition, a modified polyolefin resin, an unstretched polypropylene resin, an ethylene propylene copolymer, an ethylene propylene icetactic block copolymer or an ethylene propylene syndiotactic block copolymer between the insulating film 140 and the functional composite layer. An additional layer may be further provided. The reason for using such a structure is that a structure in which heterogeneous polymer layers are arranged has a lower heat exchange efficiency than a structure in which a single insulating film or a functional composite layer is added to block the influence of outside air or bet. This is because it acts as a buffer.
