As a new product, the glass film was welcomed by the market, another reason is that - energy. In recent years, many buildings and houses are almost closed by large windows, floor glass doors (balcony), although the large windows to improve the appearance of the room, but the heat was more room to pass. Increase the room air-conditioning electricity. The glass film is there is help to reduce energy consumption.
of building energy consumption in the doors and windows, walls, roof, retaining the four components in the ground, the insulation performance of windows and doors least is the impact on the quality of indoor thermal environment and building energy-saving one of the main factors. Envelope to the typical components of the current terms of the energy consumption of windows and doors building envelope parts accounts for about 40% -50% of total energy consumption. According to statistics, under the conditions of heating or air conditioning, single glass windows in winter heat losses by about 30% of heating load -50%, the summer heat by solar radiation through the glass window of a single injection of cold room and consumed about Air conditioning accounts for 20% -30% load. Windows of the building heat loss is similar in Canada and other northern countries more than 2 times the building, enhanced thermal insulation properties of windows, doors and windows to reduce energy consumption is to improve the quality of indoor thermal environment and improve the level of an important part of building energy efficiency.
Residential construction is characterized by
convex facade more complex shape coefficient. Currently,
pandora bracelets sale, the residential buildings to increase the lighting effect lighting and appearance of the area or using a large open fan windows, window to wall area ratio increases, is not conducive to building energy efficiency. Residential building energy efficiency standards into account the building's shape factor and the window to wall area ratio, under cold climatic regions and cold regions of the promoter region of energy saving technologies and consider the degree of maturity at this stage to determine the limits of Heat Transfer Coefficient. In order to adapt the building around
different climate conditions to meet the energy requirements of the building envelope thermal performance requirements more reasonable,
pandora charm, according to this standard with air conditioning heating degree days degree days HDD18 CCD26 as indicators of climate partition will be cold and cold regions is subdivided into five different climate area. The climate in which the building under the Building Division to determine a reasonable building envelope thermal performance parameters, respectively,
pandora uk, raised the heat transfer coefficient of building envelope and the outer limit of shading coefficient of window limits.
in cold and cold areas, heating, indoor and outdoor temperature difference of heat transfer in heat loss dominant. Therefore, the window (including the transparent part of the balcony doors) require a higher heat transfer coefficients. Window on the level of building energy consumption are two aspects of heat transfer coefficient of windows in winter heating, air conditioning in summer heat when the temperature difference between indoor and outdoor; The other is the window of influence of solar radiation caused by the indoor heat gain. Winter, through the window into the interior of the solar radiation is conducive to building energy efficiency, therefore, reduce the heat transfer coefficient of windows is to reduce the window of inhibition of heat transfer temperature difference between one of the main heat loss; and summer, through the window into the interior of the solar radiation into heat air conditioning cooling load, thus reducing the solar radiation into the interior windows or transparent walls and reducing the temperature difference heat transfer are ways to reduce air conditioning energy consumption.
in the process of developing energy-saving windows, doors and windows of glass used in curtain wall, following the float glass, heat-absorbing glass,
pandora online, heat reflective glass, the ultra-film glass membrane with its unique optical properties,
pandora beads, good thermal performance and no security the environmental performance of the reflected light pollution has become the fastest-growing market demand in recent years, energy-saving glass. In recent years, the national policy to promote building energy efficiency, the super-film glass film production increased substantially. According to incomplete statistics, the end of 2007, China has a certain level of scale and quality of online and offline film glass film over more than 20 production lines in 2007, market sales of 1500-1700 meters, some of their products in short supply good situation there . With the cold and cold in residential building energy efficiency design standards for the formulation and implementation,
pandora necklace, will further promote the wider use of residential buildings in this area, ultra-film glass membrane, energy-efficient residential building work is bound to the glass film over film the development of other energy-saving glass broader space for development.
