Description

Functional window screen device {SCREEN DEVICE}

The present invention relates to a functional window screen device installed on an outdoor side of a building, and more particularly, to a window screen device for reducing the heat acquisition of a building from solar radiation or permitting direct radiation to increase heating efficiency, And an environmentally friendly functional window screen device capable of selectively maintaining good natural ventilation, thereby reducing the energy load required for the building, thereby enhancing energy efficiency.

In recent years, there has been an increase in the number of buildings employing large-area windows for reasons such as sight and the aesthetics of buildings. However, windows in buildings are the most vulnerable in terms of insulation, Therefore, in the country, the heat perfusion value of windows facing directly to the outside air is regulated below a certain level, and such insulation conditions are expected to be continuously strengthened in the future.

For reference, the glass constituting the window has a disadvantage in that the heat insulating performance is low due to high transmittance. If high heat is applied to the glass, the heat transmission rate is lowered but the visibility is deteriorated due to the decrease of the transmittance. In other words, when the sunlight is transmitted through the window glass, most of it is emitted as heat energy from the room. If the heat can not be efficiently controlled, a high thermal (cooling and heating) load is generated in the room, It causes.

Generally, awnings are usually installed in indoor or outdoor windows of a building, but in very hot areas, walls and roofs can also be installed for the purpose of heat acquisition or heat reduction from the outside of the building, Is the rate of reduction of the radiant heat flow through the window to the awning. It is known that a blind-like sunshade can be reduced by 20% when installed in a room, but it is known that the effect is reduced to 80% when installed outside a building.

However, since such an awning device serves to shut off the sunlight, there is a disadvantage that it is not in conformity with the original installation purpose of the window. In addition, since the domestic climate is large, the interior shade is mostly applied, but a high reflectance shade is applied However, most of the influxes are stored in the room, resulting in the greenhouse effect.

In order to overcome such disadvantages, there have been proposed new technologies such as triple glazing, an infrared ray blocking film, a flood control window, and a blind window.

That is, the triple-glazed double-layered glass has an advantage of securing visibility although the price is high, but it has a disadvantage that the heat transmission rate is relatively high due to the characteristics of the glass, There is a disadvantage that it is difficult to expect a high insulation effect due to adhesion or formation of a metallic film or a ceramic coated film. In addition, in the case of other flood control window or blind window, there is a limit to insulation and shading performance .

For example, when a heat insulating member such as a curtain, a screen, or a blind is installed in a room, the thermal energy has already entered the room. Therefore, there is a disadvantage in that the blocking effect is low in terms of the total amount of energy, Thereby inducing allergies, thus seriously threatening indoor comfort.

Particularly, these heat insulating members hinder the view of the window, which is a function of the window, and hinder indoor living characteristics. In winter, the heat insulating part is not solved and the heating efficiency is lowered due to sunlight blocking.

Therefore, it is urgent to develop a technology that can increase the energy efficiency by reducing the energy load required for the building without hindering the indoor residence, the view and the view.
