technical field

The utility model belongs to building energy saving and related technologies.

Background technique

In the thermal insulation design of buildings, in recent years, corresponding measures have been taken for external walls, roofs, doors and windows, etc., and have received good thermal insulation and energy-saving effects. Among them, the thermal insulation treatment of external walls and roofs is relatively easy technically, but the thermal insulation of external doors and windows of buildings is still a weak link. At present, the commonly used method is to use aluminum alloy or plastic steel thermal insulation frame with 2 or 3 layers of insulating glass. Airtight glass doors and windows, from the use effect, have received a certain effect of heat preservation and sound insulation. In the cold northern regions, double doors and windows are also used, that is, two sets of doors and windows to further improve the effect of heat preservation. Better thermal insulation and sound insulation effects are also non-metallic thermal insulation frames with 2-layer or 3-layer insulating glass airtight glass doors and windows, but they are expensive.

According to the analysis of the heat dissipation of the building, after the insulation treatment of the outer wall and roof, the problem of heat loss from the doors and windows is highlighted, and its long-term use energy consumption accounts for more than 50% of the long-term use energy consumption of the entire building. The airtight glass doors and windows with 2 or 3 layers of insulating glass with aluminum alloy or plastic-steel thermal insulation frame have an unsatisfactory thermal insulation effect. Especially in winter, the heat loss of doors and windows in northern buildings is more prominent. In this case, the heating system or self-heating system needs to provide more heat to maintain the temperature in the building, which requires greater energy consumption. This means that if the heat loss of building doors and windows can be minimized, the effects of heat preservation and energy saving can be achieved. For the application of double windows, although better thermal insulation effect can be obtained, the investment price paid is also considerable. Another disadvantage is that double windows are redundant in non-heating seasons, which also affects the visual effect of the interior space.

In recent years, domestic research on frame materials, glass quality, glass structure, and sealing methods of building doors and windows has made great progress, which has improved the energy-saving level of building doors and windows, but there is still a large gap compared with advanced countries in general , still needs to be improved. At the same time, in terms of technological innovation, it is imperative to seek a more practical, effective and economical way of heat preservation and energy saving.

Throughout the development of energy-saving technology for building doors and windows, energy-saving doors and windows, that is, thermal insulation, sound insulation, and dust-proof doors and windows, are developing towards high, precise, and cutting-edge development. Using modern technology and materials, the energy-saving indicators of high-grade building doors and windows can reach a considerable height, but the cost It is also quite high, and the high cost will obviously restrict its wide application. Therefore, it is also a way worth exploring whether to seek other methods in technology, including auxiliary technologies to improve the effect of heat preservation and energy saving.

The thermal insulation performance of building doors and windows is reflected in the material of the door and window frame and the heat insulation treatment method, the glass material and the heat insulation treatment method, the sealing material and the sealing method, the treatment of the connection between the door and window frame and the building, etc. These factors all affect the insulation effect of the door and window , especially the building doors and windows being used, as time goes by, the thermal insulation performance will gradually decrease, and auxiliary thermal insulation and energy-saving technologies are also needed to solve this kind of problem.

There are no publicly issued publications or publicly published technical documents about the auxiliary technology of building door and window insulation and energy saving.

detailed description

The thermal conductivity of different building materials varies greatly. For example, the thermal conductivity of foam plastic is 0.035W/(m k), and the thermal conductivity of marble is 3.500W/(m k). Building materials with low thermal conductivity are used as building insulation. The material can receive a good thermal insulation effect, and the use of foam insulation boards on the exterior walls and roofs of buildings basically solves the thermal insulation problems of exterior walls and roofs of buildings. As for the insulation of doors and windows on the exterior of the building, due to the need for lighting and ventilation, the glass of the doors and windows and their frames have become indispensable materials. In order to overcome the shortcomings of high thermal conductivity of single-layer glass, double-layer insulating glass doors and windows, triple-layer insulating glass doors and windows, etc. are often used to increase the thermal insulation performance of doors and windows on the exterior of buildings. When double-layer insulating glass doors and windows are used, the thermal conductivity can be greatly reduced due to the barrier effect of the intermediate air layer. Judging from the effect of practical application, the thermal insulation effect of double-layer insulating glass doors and windows, triple-layer insulating glass doors and windows, and double doors and windows is superior, especially the thermal insulation effect of double doors and windows is better. The reason for the good thermal insulation effect of these kinds of doors and windows is that they all take advantage of the hindering effect of the closed air environment on heat conduction.

From the thermal conductivity theory of materials and the effect of practical application, the amount of air contained in the material has a great influence on the thermal properties of the material, because the thermal conductivity of air is much smaller than that of solid matter. The thermal conductivity of commonly used ordinary single-layer glass is about 2.6W/(m·k); the insulating glass composed of double-layer glass, in addition to one more layer of glass, has the thermal barrier of the middle air layer, and the thermal conductivity can be reduced to 1.3 About W/(m·k), its thermal insulation capacity is about double that of single-layer glass, indicating that the thermal barrier of the air layer in the middle of insulating glass plays a key role in the thermal insulation capacity of windows; and the thermal conductivity of closed air ≤0.025W/(m·k), therefore, it is promising to make full use of the low thermal conductivity of closed air to conduct thermal insulation and energy saving of doors and windows on the exterior of buildings.

Utilizing the principle of low thermal conductivity of airtight air, the thermal insulation and energy-saving inflatable building doors and windows of the utility model are made of elastic PVC or elastic rubber materials. On the inside of the house, due to the airtight air of the doors and windows of the inflatable building itself and the good resistance of the air between the doors and windows of the inflatable building and the existing fixed doors and windows to the internal and external cold or hot airflow, a good thermal insulation effect can be obtained, which is comparable to the existing facilities. The utility model has the advantages of simplicity, flexibility, convenience, low input cost and significant energy saving.

Use elastic PVC or elastic rubber to make various heat-insulation and energy-saving inflatable building doors and windows in required shapes. There are two types of elastic PVC or elastic rubber: transparent and opaque. Where lighting is not required. Both transparent and opaque thermal insulation and energy-saving inflatable building doors and windows can be painted with various colorless or colored patterns on their surfaces to make them have decorative effects.

Figure 1 is a special case of the application of thermal insulation and energy-saving inflatable building doors and windows. The actual shape depends on the actual size of the inner frame of the building doors and windows. shaped situation. The thickness of thermal insulation and energy-saving inflatable building doors and windows depends on the ambient temperature and the thermal insulation effect to be achieved, and the thickness ranges from 30mm to 200mm. In order to achieve a good thermal insulation effect, polyethylene foam sealing tapes [4] are attached around the doors and windows of thermal insulation and energy-saving inflatable buildings. For doors and windows that need to be ventilated, openable and closable inflatable ventilation windows can be set on the doors and windows of thermal insulation and energy-saving inflatable buildings. For doors and windows with a large area, for the convenience of installation, use and storage, the area can be divided into several parts to make a combined thermal insulation and energy-saving inflatable building door and window.

Thermal insulation and energy-saving inflatable building doors and windows have the characteristics of simple, flexible and convenient installation, and can be installed, used or removed for storage according to the needs of the four seasons. In the application of building insulation in the north, thermal insulation and energy-saving inflatable building doors and windows can be installed in the inner frames of the existing doors and windows in winter, and they can be removed after deflation in spring and stored for reuse in winter. When it is necessary to reduce direct sunlight or western exposure in summer and save air-conditioning energy, installing thermal insulation and energy-saving inflatable building doors and windows will also receive good results.

The thermal insulation and energy-saving inflatable building doors and windows are equipped with an inflatable nozzle [2], which is convenient for inflating during installation and deflation during disassembly.

For ease of use, the doors and windows of thermal insulation and energy-saving inflatable buildings are equipped with inflatable devices [3].
