In recent years, many of the residential and public buildings around us have nearly closed large glass and floor-to-ceiling glass doors (balcony). This large-area exterior window improves the room's exterior view while clearly introducing the interior. The increase in solar radiation heat increases the electricity used in room air conditioners. In the north, the indoor and outdoor temperature difference in winter can be as high as 20-60 ° C, and the transparent transparent glass brings about a lot of heat while bringing good lighting. According to the survey, the energy consumption of doors and windows has accounted for 30%-50% of the total energy consumption of residents. In fact, in building energy consumption, building glass doors and windows is a very weak and relatively easy to ignore. Then, how to adopt an effective and economical way to solve the insulation and energy saving of building glass doors and windows and improve safety performance? First, change the sealing method of doors and windows The traditional way of opening doors and windows for Chinese people is a flat-open type, which has always dominated the history of China's 5,000-year history. At present, the common sliding doors and windows in the building are actually from Japan. This kind of opening method is simple and does not occupy indoor space, and has gradually dominated the doors and windows of buildings in China. But is this kind of push-pull opening method really good? I think that for a country like Japan, which is in a maritime climate with active earthquakes, its buildings generally choose materials with lower density, and many Japanese buildings do not design heating at all. Therefore, the sliding window is convenient and practical for a Japanese that does not involve energy loss and air quality. But for us in northern China, the choice of sliding windows is undoubtedly not suitable for energy saving and air tightness. It is best to choose a flat-open window with a rubber strip seal, which will block the air convection inside and outside the room to the maximum extent, which is energy-saving and dust-proof. Second, special treatment of the glass People may notice that the glass used in China's building doors and windows is experiencing from ordinary (white glass) - deeper color heat absorbing glass (brown glass) - light green heat absorbing glass - light green insulating glass - coated glass - - A process of development of low-emission coated glass. All of these are to solve the problem of poor thermal insulation performance of ordinary glass. However, all of the above glasses have the most deadly weakness of ordinary glass - fragile. The latest multi-functional glass film is a high-tech energy-saving product that can effectively control solar heat radiation and increase glass strength. The glass film is made of a special polyester film as a substrate, and is coated with various high reflectivity metal or metal oxide coatings by magnetron sputtering in the middle of the polyester film. A functional glass film that is pressed and has high light transmission and high heat insulation. It can filter more than 80% of the infrared rays with heat, filter more than 90% of the ultraviolet rays, and prevent the glass from being damaged. For example, a direct film on ordinary clear glass can be turned into a safety heat-insulating glass with both heat insulation and safety and anti-riot effect; a one-way see-through film can also be used instead of the curtain. Third, the use of insulating glass technology Insulating glass technology originated in the Middle Ages in Europe, and it was only 10 years since it was actually introduced to China. Its basic principle is to use a spacer in the middle of the two sides of the glass to separate, and then use a special glue for the overall sealing. Such a treatment process ensures that the double-glazed glass is dry and non-flowing air, and can achieve a sound insulation of more than 30 decibels. Since the air inside the glass has no heat convection, it is about 30% lower in heat conduction than single-layer glass. However, the main effect of insulating glass technology is reflected in its good sound insulation.
