Description

External window insulation, sound insulation, sunshade

technical field

The invention relates to a curtain, in particular to a multifunctional curtain for thermal insulation, sound insulation and sunshade of an outer window.

Background technique

1. The necessity of thermal insulation, sound insulation and sunshade for building exterior windows

(1) Thermal insulation and energy saving:

Compared with other parts of the building envelope, namely walls and roofs, windows are thin-walled and lightweight components, and are the weak link in building thermal insulation, heat insulation, and sound insulation; windows not only have the same temperature difference and heat transfer as other envelope structures Problems, there is also the problem of air infiltration heat transfer through window gaps, and solar radiation heat transfer through glass. In a heated residential building, the heat loss of the building consists of two parts: the heat loss through the envelope and the heat loss through the air infiltration through the gaps in doors and windows. The heat transfer loss of the envelope structure accounts for about 70% to 80%; the heat loss of the air penetration in the gaps between doors and windows accounts for about 20% to 30%. Taking a typical multi-storey residence in Beijing as an example, the heat transfer loss through the envelope structure accounts for about 77% of the total loss, and the air infiltration heat loss through the gaps between doors and windows accounts for about 23% to 25%. The total heat loss of the window, that is, heat transfer heat loss and air penetration heat loss accounts for about 50% of the total heat loss. It can be seen that the window is the weak link of heat consumption and the key part of energy saving. Improving the thermal insulation performance of building windows and strengthening the airtightness of windows are the key measures for energy saving.

(2) Sound insulation:

Most of the urban residences in northern my country are multi-storey buildings. There are a large number of residences facing urban streets, and some residences are on both sides of the railway line. Motor vehicles or other noises have a great impact on the residences at night, greatly affecting people's normal life and rest.

(3) sunshade:

my country's residences emphasize the north-south orientation, but in summer, less consideration is given to the sunshade of the south-facing exterior windows of the residence. In summer, the sunlight directly irradiates the interior through the south-facing exterior windows of the residence, which makes the indoor temperature too high, affects people's living comfort, and reduces the learning environment. and work efficiency. Turning on the air conditioner for cooling not only wastes a lot of electric energy, but also increases the emission of exhaust gas from the air conditioner.

2. Current situation at home and abroad

(1) Status abroad

Western developed countries have carried out building energy conservation work since the 1970s, and have achieved outstanding results so far. With the advancement of building energy-saving work, people's requirements for energy-saving doors and windows are getting higher and higher, making energy-saving doors and windows present a multi-functional and high-tech development trend. It can be seen from Table 1 that people's functional requirements for doors and windows range from simple light transmission, wind protection, and rain protection to energy saving, comfort, and flexible adjustment of lighting. Technically, it ranges from the use of ordinary flat glass to the use of insulating glass and various heat-reflecting glasses.

Table 1 Functional and technical performance changes of foreign doors and windows

The performance of foreign window products is excellent, but the price is expensive, which is difficult for ordinary families to accept.

(2) Domestic status

There is a big gap between my country's current building energy-saving level and developed countries, and the gap in energy-saving of building doors and windows can be prominently reflected in the following two aspects:

① In terms of building energy consumption, the total energy consumption per unit of residential buildings in my country is about three times that of foreign developed countries, the external windows are 1.5 to 2.2 times, and the air penetration of doors and windows is 3 to 6 times;

② In terms of energy-saving standards, most developed countries have revised energy-saving standards for many times, and the relevant energy-saving indicators have reached ^a relatively high level. K), France requires 2.25~2.45W/(m ² ·K), China's severe cold area standard requires K value to be 2.0~3.0W/(m ² ·K), cold area standard requires K value to be 4.0~4.7W/ (m ² ·K), the energy-saving standard of residential buildings in hot summer and cold winter regions stipulates that the K value of windows is 2.5~4.7W/(m ² ·K). Table 2 shows the heat transfer coefficient of single-layer external windows in my country

Table 2 Calculated value of heat transfer coefficient of single-layer external window W/(m ² ·K)

However, in real life, due to the lack of relevant knowledge of the majority of residents, the blind pursuit of fashion, the pursuit of modernization of the surface, and the quality of window construction, the actual thermal insulation performance of exterior windows in northern my country is lower than the standard requirements.

The obvious gap is enough to show that the thermal insulation performance of exterior windows in the vast northern regions of my country has not yet met the relevant requirements.

3. Measures to improve the thermal insulation performance of external windows

(1) Reduce the heat transfer coefficient of the outer window structure, thereby reducing the heat transfer loss of the outer window itself; increase the air tightness of the outer window, and reduce the heat loss caused by cold wind penetration. It is advisable for households to choose energy-saving windows with better thermal insulation performance as external windows, but due to the high cost of energy-saving windows, it is still unaffordable for the majority of low- and middle-income households.

(2) Increase the total thermal resistance of the outer window and improve the comprehensive thermal insulation performance and sealing performance of the outer window by adding thermal insulation components for the outer window.

The winter in northern my country is very cold, the outdoor temperature is extremely low at night, and the heat in the living room is lost quickly, especially at night. During the daytime in winter, the sunlight received through the exterior windows on the south side can rapidly increase the room temperature and improve the indoor thermal environment. It can be said that during the daytime from 9:00 to 14:00, the south-facing exterior windows of the residence are heat-gaining components; while in the afternoon at 15:00 After 00, as the amount of solar radiation decreases and the outdoor temperature drops, the external windows gradually change from heat-gaining components to heat-dissipating components. As the outdoor temperature drops at night, the heat loss of residential external windows becomes more obvious. Therefore, adding external window insulation components is an effective method.
