Abstract

The utility model relates to a double-layered ventilation reversible window which comprises a window frame, double-layered glasses and double-layered ventilation louvers. The structure of the window is divided into an upper part, a middle part and a lower part; one of the ventilation louvers is arranged at the upper part; the middle part comprises float clear glass and heat insulating glass; and the other ventilation louver is arranged at the lower part, thereby ensuring that air can flow between the two layers of glass in the middle freely. The utility model can reinforce heat insulation effect of an external window, reduce cooling and heating load of an air conditioner, decrease building air conditioning energy consumption, and achieve the effect of insulation and energy conservation.

Description

The reversible window of double-layer ventilation

Technical field

The utility model relates to a kind of window, particularly a kind of double window.

Background technology

Building energy consumption is one of energy consumption rich and influential family, in the total energy consumption of China, and the sizable ratio of building energy consumption account, about about 30%, how reducing building energy consumption is an important topic, building energy conservation is to be related to the major issue that can China's economy sustainable development.Building energy consumption generally has air-conditioning, illumination, equipment (as computer, duplicator, printer, escalator, elevator etc.), domestic hot-water supply energy consumption etc. several, general air conditioning energy consumption maximum, account for more than 40% of total building energy consumption, building function difference, shared ratio difference.Air conditioner load is generally conducted heat by wall heat transfer, exterior window and gets hot, illuminating and heat radiating, human-body radiating, equipment cooling etc. with the direct transmission of the sun and form.Because the thermal transmittance of exterior window is big, can directly transmission solar heat, so be the heat insulation and preservation effect link of weakness relatively in the building external envelope structure.

Summary of the invention

The utility model is at the existing bad problem of domestic window heat preservation and insulation, the reversible window of a kind of novel double-layer ventilation has been proposed, constitute by heat-protecting glass and transparent float glass layer glass, can strengthen the heat insulation and preservation effect of exterior window, reduce the hot and cold load of air-conditioning, reduce the air conditioning energy consumption of building.

The technical solution of the utility model is: the reversible window of a kind of double-layer ventilation, comprise window frame, double-layer glass, double-layer ventilation blinds, divide upper, middle and lower three parts on the window construction, top comprises upper outer layer ventilating blind and top internal layer ventilating blind, mid portion comprises float glass process clear glass and heat-protecting glass double-layer glass, float glass process clear glass and heat-protecting glass double-layer glass inside and outside can be changed arbitrarily, the lower part comprises outer ventilating blind in bottom and bottom internal layer ventilating blind, can guarantee that air can flow freely in middle layer glass.

Described window frame can be in horizontal or vertical direction turnback.

The beneficial effects of the utility model are: the reversible window of the utility model double-layer ventilation is strengthened the heat insulation and preservation effect of exterior window, reduces the hot and cold load of air-conditioning, reduces the air conditioning energy consumption of building, has reached the effect of heat preservation energy-saving.

Description of drawings

Fig. 1 is the reversible window cross-sectional view of the utility model double-layer ventilation;

Fig. 2 is the reversible window of the utility model double-layer ventilation user mode in winter figure.

The specific embodiment

The reversible window construction schematic diagram of double-layer ventilation as shown in Figure 1, comprise window frame, double-layer glass, double-layer ventilation blinds, window frame is reversible, can be in horizontal or vertical direction turnback, divide upper, middle and lower three parts on the window construction, top comprises upper outer layer ventilating blind 7, top internal layer ventilating blind 1, mid portion comprises float glass process clear glass 2 and heat-protecting glass 6 double-layer glasss, the lower part comprises outer ventilating blind 4 in bottom and bottom internal layer ventilating blind 3, guarantees that air can flow freely in middle layer glass.

The characteristics of double-layered ventilation reversible window are: 1. be made of inside and outside layer glass; 2. cavity between layer glass Interior air is flowing by gravity-flow ventilation; 3. forms are reversible, namely can be horizontal or vertical side To rotating 180 degree. It has two kinds of use patterns: 1. summer mode as shown in Figure 1 under summer mode, Heat-protecting glass is towards outdoor, and absorption solar energy and stop portions solar energy enter indoor, and float transparent glass Towards indoor. Air mobile is that outer ventilating blind enters cavity between the layer glass from the bottom by outdoor, Pass through the upper outer layer ventilating blind again to outdoor environment from cavity then, the purpose of ventilation is layer glass Between high temperature air take away, to reduce the summer air-conditioning refrigeration duty. 2. winter mode as shown in Figure 2 in the winter time Under the pattern, float transparent glass is towards outdoor, and heat-protecting glass is towards indoor. Air mobile be by indoor from Bottom internal layer ventilating blind enters the cavity between the layer glass, ventilates by the top internal layer from cavity then Blinds arrives indoor again, and the purpose of winter ventilation is the high temperature air between layer glass to be taken to indoor, is the chamber Interior heating is to reduce the air conditioner heat load in winter.

Claims

1, the reversible window of a kind of double-layer ventilation, comprise window frame, double-layer glass, it is characterized in that, also comprise the double-layer ventilation blinds, divide upper, middle and lower three parts on the window construction, top comprises upper outer layer ventilating blind and top internal layer ventilating blind, and mid portion comprises float glass process clear glass and heat-protecting glass double-layer glass, float glass process clear glass and heat-protecting glass double-layer glass inside and outside can be changed arbitrarily, and the lower part comprises outer ventilating blind in bottom and bottom internal layer ventilating blind.

According to the reversible window of the described double-layer ventilation of claim 1, it is characterized in that 2, described window frame can be in horizontal or vertical direction turnback.
