虽然会展建筑的门窗面积所占比例较少，但是门窗因为其与外界热交换频繁，保

Although the door and window area of ​​the exhibition building accounts for a small proportion, the door and window are frequently exchanged with the outside world, and the thermal insulation performance is not as good as the wall. It is the main part of the heat exchange between the building and the outside world. Therefore, in the design process of the energy-saving exhibition building It is particularly important to choose doors and windows with good thermal performance. At present, the most widely used and most widely used thermal insulation glass on the market are: insulating glass, heat reflective coated insulating glass and Low-E glass. These three glasses all use certain technologies to achieve glass insulation, reduce heat transfer, increase The large glass reflects sunlight, etc., thereby ensuring the heat and comfort of the indoor environment. Insulating glass, as the name implies, is usually double-layer or multi-layer glass. The air between the glass is evacuated or filled with inert gas with poor thermal conductivity through a certain technology, which reduces the heat transfer coefficient of the glass and reduces the heat dissipation of the window; heat-reflective coating insulating glass On the basis of insulating glass, one or more layers of metal, non-metal or oxide films are coated on the glass surface to increase the reflectivity of solar radiation, reduce solar radiation and maintain indoor temperature; Low-E glass construction method It is also coated on the glass surface to block solar radiation, but Low-E glass can not only effectively resist ultraviolet radiation during the day, but also keep warm at night, which greatly improves the energy saving of the building. <br>The thermal insulation performance of doors and windows is mainly affected by the heat transfer coefficients of doors and windows frames and curtain walls. The walls of doors and windows in exhibition buildings are large. Materials with high thermal resistance should be used for doors, windows and glass curtain walls. The more hollow cavities in the cross-section of the door and window components, the smaller the heat transfer coefficient, so the materials with more cross-sectional cavities are used in the selection of materials for exhibition buildings

Although the exhibition building's window and window area is relatively small, but the doors and windows because of the frequent heat exchange with the outside world, thermal insulation performance is not good wall, is the main part of the building and external heat exchange, so in the design process of energy-saving exhibition building to choose the doors and windows with good thermal performance is particularly important. At present, the most widely used, the most widely used thermal insulation glass is: hollow glass, thermal reflection coating hollow glass and Low-E glass, these three glass are the application of certain technology to make glass to achieve insulation, reduce heat transfer, increase the reflection of glass to the sun, so as to ensure the heat and comfort of the indoor environment. Hollow glass as the name implies, is usually double or multi-layer glass, through a certain technology between the air between the glass or fill the inert gas with poor thermal conductivity, reduce the heat transfer coefficient of the glass, reduce the cooling of the window; Block solar radiation, but Low-E glass not only can effectively resist ultraviolet radiation during the day, but also keep warm at night, greatly increasing energy savings in buildings.<br>The insulation performance of doors and windows is mainly affected by the heat transfer coefficient of door and window frames and curtain walls, the exhibition building's door and window wall area is larger, the doors and windows and glass curtain wall should use thermal resistance material. The more hollow abdominal cavities in the section of the door and window components, the smaller the heat transfer coefficient, so the material slotted in the exhibition building is used more materials with more components in the sectionsection abdominal cavity

Although the proportion of the door and window area of the exhibition building is small, the door and window are the main parts of the building and the outside heat exchange because of their frequent heat exchange with the outside world, and their thermal insulation performance is not as good as the wall, so it is particularly important to select the door and window with good thermal performance in the design process of energy-saving exhibition building. At present, the most widely used insulating glass in the market are: insulating glass, heat reflection coated insulating glass and Low-E glass. These three kinds of glass are all made by using certain technology to make the glass achieve heat preservation, reduce heat transfer, increase the reflection of the glass on the sun, etc., so as to ensure the heat and comfort of the indoor environment. As the name suggests, hollow glass is usually a double-layer or multi-layer glass. Through certain technology, the air between the glass is pumped out or filled with inert gas with poor thermal conductivity, which reduces the heat transfer coefficient of the glass and reduces the heat dissipation of the window. The heat reflection coated hollow glass is based on the hollow glass, which is coated with one or more layers of metal, non-metal or oxide films on the surface of the glass to increase The reflectivity of the solar radiation can reduce the solar radiation and maintain the indoor temperature; the construction method of Low-E glass is also to attach a coating on the glass surface to block the solar radiation, but the Low-E glass can not only effectively resist the ultraviolet radiation in the daytime, but also keep warm at night, which greatly improves the energy saving of the building.<br>The thermal insulation performance of doors and windows is mainly affected by the heat transfer coefficient of doors, windows, frames and curtain walls. The area of doors, windows and walls of exhibition buildings is large. Doors, windows and glass curtain walls should be made of high thermal resistance materials. The more the hollow cavity in the section of door and window components, the smaller the heat transfer coefficient. Therefore, the materials with more sections and cavities are used in the selection of exhibition buildings
