Abstract

The application discloses a heat-insulating sun-shading type double-layer window, which installs an outer layer window and an inner layer window on the same building outer window opening, and the outer layer window frame and the inner layer window frame are connected into one body with reinforcing ribs to improve The wind pressure resistance of the entire window; electric or manual built-in thermal curtains and built-in sunshades are installed in the space between the outer window and the inner window. The built-in thermal curtain is used for thermal insulation at night, and the built-in sunshade is used for Sunshade during the day in summer; the inner window glass is slightly thinner, and the outer window glass is slightly thicker to improve the sound insulation performance of the entire window. The positive effect of this application is: (1) when there is sunshine in the daytime in winter, the windows can pass through, fully utilize solar energy for heating, and reduce heating costs; when there is no sunlight in the daytime in winter, the outer windows and inner windows are closed, and the built-in curtains are opened, and the windows The thermal insulation performance is good, and the indoor lighting is good; in winter, the outer and inner windows are closed at night, and the built-in thermal insulation curtain and built-in sunshade are drawn, or only the built-in thermal insulation curtain is drawn, the thermal insulation and sound insulation performance of the window is good; ( 2) In summer, the sunshade, heat insulation and sound insulation effect of the window is good, and the air conditioner has a small operating load. (3) The south wall of the house can be made into windows to improve the indoor solar heat storage heating effect and lighting effect.

Description

Insulated and shaded double windows

technical field

This application concerns windows.

Background technique:

The hollow glass windows currently being promoted and used have good thermal insulation performance in winter, and the sunshade Low-E hollow glass windows also have good sunshade and heat insulation performance in summer, which can basically meet the requirement of 65% building energy saving. However, in Hollow glass windows cannot make full use of solar energy in winter, and the heating effect of windows is poor.

In fact, the performance of windows should be dynamic, that is, to make full use of solar energy for heating during the day in winter, and to keep warm at night to save heating costs; The performance of the current high-performance energy-saving windows is fixed, which cannot solve the contradiction between thermal insulation and heating.

Contents of the invention

The purpose of the invention is to make the window have dynamic energy-saving performance, which integrates heating, thermal insulation and sunshade. The technical solution is:

Install outer windows and inner windows on the outer window opening of the same building, and connect the outer window frame and the inner window frame with reinforcing ribs to improve the wind pressure resistance of the window;

Install electric or manual built-in thermal curtains and built-in sunshade curtains in the space between the outer windows and the inner windows;

The outer windows adopt single-layer transparent glass (that is, white glass), preferably ultra-white glass, so that the sun's radiant heat can fully enter the room in winter.

The inner window can adopt other glass such as single-layer transparent glass or insulating glass or heat-reflecting coated glass.

The built-in thermal insulation curtain is used for heat insulation at night, and the built-in sunshade curtain is used for shading during the day in summer;

When the inner window adopts single-layer heat-reflective coated glass, it is not necessary to install the built-in sunshade curtain, but only the built-in thermal insulation curtain;

When the inner window adopts transparent insulating glass, only the built-in sunshade can be installed;

The inner layer of window glass is slightly thinner, the outer layer of window glass is slightly thicker, or the thickness can be the same;

The opening and closing mode of the window is that both the inner layer window and the outer layer window are push-pull, or the outer layer window is opened flat outwards while the inner layer window is push-pull;

The window profiles of the present application can use materials such as glass fiber reinforced plastics, aluminum alloys, aluminum-plastic composites, plastic steel, and plastics.

The positive effect of this application is:

1) In winter, when there is sunlight during the day, close the outer windows and open the inner windows and built-in curtains, which can make full use of solar energy for heating and reduce heating costs; when there is no sunlight during the day, close the outer windows and inner windows and open the built-in curtains. Curtains, the thermal insulation performance of the windows is good, and the indoor lighting is good; at night, the outer and inner windows are closed, and the built-in curtains are drawn, so that the thermal insulation and sound insulation performance of the windows is good;

2) In summer, close the outer and inner windows, pull up the built-in sunshade curtain, and open the built-in heat preservation curtain, then the windows will have good sunshade, heat insulation and sound insulation effects, and the air conditioner will have a small operating load.

3) Since the window of this application has excellent heating, thermal insulation, sunshade and sound insulation properties, the south wall of the house can be made into a window and a large floor-to-ceiling window with a guardrail, so as to improve the indoor solar heat storage heating effect and lighting effect.

Fig. 1 is a schematic vertical cross-sectional view of an embodiment of the window of the present application.

In the figure: 1—wall; 2—outer window frame and inner window frame connected by reinforcing ribs; 3—inner window; 4—inner window glass; 5—built-in Sunshade; 6—built-in insulation curtain; 7—outer window; 8—outer window glass.

Detailed ways

The technical solutions of the present application will be further described below in conjunction with specific embodiments.

As shown in Figure 1, it comprises the outer layer window sash and the inner layer window sash 2 that are connected as a whole with reinforcing ribs, and the inner layer window 3 and the outer layer window 7 are installed on the window frame 2; 3 and the outer window 7, install the built-in sunshade curtain 5 and the built-in heat preservation curtain 6; the outer window 7 uses white glass with a thickness of 6mm, and the inner window 3 uses white glass with a thickness of 4mm; the window profile is aluminum alloy, and the built-in The sunshade curtain 5 is an aluminum alloy louver, and the built-in thermal insulation curtain 6 is made of terry cloth and has an artistic pattern.

Claims (1)

1, heat insulation and sunshade type double-layer window is characterized in that:

(1) outer window and internal layer window are installed on same external window of building hole, outer window window frame and internal layer window window frame link into an integrated entity with reinforcing rib, to improve the resisting wind press capacity of window;

(2) electronic or manual built-in heat insulation curtain and built-in abat vent are installed in the spaced cavities between outer window and internal layer window, it is heat insulation that the built-in heat insulation curtain is used for night insulation, and built-in abat vent is used for sunshade on daytime in summer;
