Description

A high-efficiency energy-saving window

1. Technical field

The utility model belongs to the technical field of building windows, in particular to an energy-saving building window.

2. Background technology

Although the proportion of windows in the building envelope is not large, it generally only accounts for about 1/5 of the building area and 1/3 to 1/5 of the surface area of the outer envelope. However, windows are thin-walled and light-weight components. Therefore, it is the weak link of building thermal insulation and heat insulation, which makes the energy loss through windows account for more than half of the energy consumption of the building envelope, accounting for about 30% to 40% of the energy consumption of building heating and air conditioning. Therefore, for the inefficiency of windows, it is believed that the heat loss of windows is more than 10 times the heat loss of walls. On the other hand, the proper application of natural lighting from windows will save 50% to 80% of lighting energy consumption, and at the same time reduce the increased cooling load due to waste heat generated by lighting. This part of the additional load accounts for 3% of the total energy consumption. %~5%. It is of great significance to develop energy-saving windows.

Due to the particularity of windows in architecture, people have done a lot of research on how to reduce the heat transfer performance of windows and improve the ability of windows to block the sun. For example, the patent No. ZL94226094 "outside louver type energy-saving window" discloses that on the outside of the window frame, there are several louvers with a certain inclination angle that are relatively fixed to the window frame. sports. Although the window can effectively block the summer sunlight outside the window, the natural lighting is poor, thereby increasing the lighting energy, and the sunlight that is beneficial to heating in winter is poorly utilized, which increases the heating energy consumption in winter, and the louvers on the outdoor side are easy to accumulate Dust, difficult to clean, inconvenient to use, and easily damaged by the sun and rain. Another example is the "high-efficiency energy-saving window" patent with the patent number ZL2006200112138, which discloses that in the frame structure of the window sash, two layers of glass and a transparent heat insulation layer formed by several layers of transparent plastic films and film skeletons inserted between them are installed. Rubber and plastic sealing strips are used for glass sealing. Although this window has the effect of natural lighting, for areas with strong solar radiation in summer, its sunshade performance is poor, and the problem of blocking sunlight in summer cannot be effectively solved. It is not suitable for the southern regions where the summer is hot and the sun is like fire. Another example is the patent No. 200520064026 "energy-saving window with adjustable temperature", which discloses that the inner and outer sash sides of the multi-layer glass window are connected by hinges, and the heat insulation strip is arranged at the window frame, and the inner and outer sash is arranged. The louvers, the louvers can be raised and lowered. Although this window solves the cleaning problem of dust and mist between the double windows and the problem of heat preservation in winter and heat insulation in summer, because the louvers can only be lifted and lowered but not the angle of inclination can be adjusted, so the reflection effect of solar radiation at different times is not good. It is good, and because only relying on the louvers between the window sash to achieve sunshade, a large amount of solar radiation heat cannot be blocked outside the window, and a considerable part of the radiant heat still enters the inner and outer window sash, and thus enters the room through heat conduction, let alone solve the problem of sunshade heat insulation and heat insulation at the same time. Problems with natural lighting.

3. Contents of the invention

The purpose of this utility model is achieved as follows: a high-efficiency energy-saving window mainly includes a window frame, a window glass, a venetian roller blind and its adjusting device, an external sunshade and its telescopic device, etc. The window frame is made of heat-breaking bridge steel or aluminum alloy profiles, which can effectively block the direct heat conduction inside and outside the window, thereby reducing the loss of indoor heat and also reducing the introduction of outdoor heat. The window glass is two layers of ordinary glass installed in the window frame, with a gap of 50 mm to 120 mm in between for the installation of venetian blinds. The venetian shutter is composed of several plastic sheets, wood chips or bamboo pieces, etc., and the two ends of the louver are passed through the two ends of the louver through nylon or steel wire and fixedly connected to form a venetian roller blind. The venetian roller blind is installed on two windows. In the gap between the glass, it is beautiful and easy to clean. The number and size of the shutters are determined according to the size of the window. According to the requirements of natural lighting in the room, the venetian roller blind can adjust the inclination or outward inclination or horizontal or vertical position of the louvers through its adjustment device, or adjust the venetian roller blinds to be fully lowered, partially lowered or fully retracted, which is very flexible and convenient , fully meet the requirements of indoor lighting. Install an outer sunshade with a telescopic size of 1-800mm or no extension on the outer side of the upper part of the window frame. The outer sunshade is composed of an outer sunshade fabric and an outer sunshade skeleton, and the two are fixedly connected. The outer sunshade fabric is made of special sun fabric or acrylic or polyester or linen. The surface fabric and the outer sunshade frame are made of light aluminum alloy or hard plastic. Roller blinds and outer sunshade fabrics are mainly blue or light green, or bamboo or trees are painted on their surfaces. The adjustment device of the venetian blind is composed of a lifting adjustment device and an inclination adjustment device. The lifting adjustment device of the venetian blind adopts manual control of the push rod installed in the push rod chute on one side of the window frame to drive the shaft and the pull rope connected to both sides of the louver to realize the lifting of the venetian blind. The inclination angle adjustment device of the louver adopts manual control of the knob installed on the lower part of the other side of the window frame to drive the reel and the pull rope connected to one side of the louver to realize the rise of one side of the louver, so as to realize the difference of the louver. slope. The outer sunshade telescopic device adopts manual control and is installed on a pull rod on one side of the window frame provided with a knob to drive the reel to rotate, so as to realize the expansion and contraction of the outer sunshade fabric on the sunshade frame. When the outer sunshade fabric is retracted, it is rolled in the roll of the outer sunshade and is protected; when the outer sunshade fabric is stretched, it can block the sun.

The whole window of the utility model is a whole, including window frame, window glass, inner and outer sunshade and adjusting device thereof. When in use, the window only needs to be fixedly installed according to the requirements of building installation, and then it can be used. For winter or seasons with low temperature, the solar radiation during the day is beneficial to the interior at this time, so the outer sunshade of the window is fully retracted at this time, that is, there is no outer sunshade, and the shutters between the glass are also closed. It is in a fully folded state, so that sunlight can fully enter the room through the window glass. At this time, the outdoor sunlight may be too strong, which may cause glare indoors. Therefore, the venetian blinds between the glass can be lowered, and the inclination angle of the blades can be adjusted to avoid glare. At night, in order to minimize the heat dissipated to the outside through the windows, all the louvers between the window panes are lowered at this time, and the louver blades are adjusted to be closed, that is, each louver is in a vertical state to enhance the heat insulation performance of the window. For summer or seasons with high temperature, in order to block the strong solar radiation during the day, different horizontal external shading extension sizes should be set according to the solar radiation intensity at different times, the sun position angle and other data to meet the needs of shading and natural lighting. At the same time, in order to cooperate with the use of external sunshade, the lowering degree of the louver roller blinds between the glass and the inclination angle of the louver blades can be adjusted in a timely manner according to the needs, so as to achieve the comprehensive effects of sunshade, daylighting and anti-glare.
