产品特性(国外英文资料) Product features I about Windows and doors With the development of human society, the function of the doors and Windows by the original - ventilation, ventilation, wind, are endowed with more times meaning - building decorations, the art of life, energy saving products to protect the environment. II about energy saving Refers to save building energy saving, heating heating, air conditioning and refrigeration, lighting lighting and indoor air purification, adjust humidity, improve the energy consumption of the bedroom environment quality, also includes the use of solar energy, geothermal energy (water), the comprehensive energy saving technology of engineering. Building doors and Windows are the composite part of the buildings enclosure structure, which is the most active and sensitive part of the heat exchange of buildings, and is five to six times the heat loss of the wall. How large is the total consumption of doors and Windows? Heat consumption of residential buildings in heating were analyzed, and this kind of building heat consumption by building palisade structure heat transfer heat consumption and the air gap osmotic quantity through doors and Windows of two parts. According to the results of the analysis on actual measurement data is: the heat transfer heat consumption of the window and air infiltration heat consumption, accounting for about 50% of the total heat consumption, the concept of energy saving in the national standard including the strength of the doors and Windows (wind resistance, air tightness. The specific requirement of water tightness. Several ways of heat transfer of doors and Windows: (1) convection heat; (2) radiative heat transfer; (3) heat conduction (heat transfer) If the most effective blocking of these three types of heat exchange is possible, it can be described as the best energy-saving door and window. The first is to design consideration from the structural design of the doors and Windows, including the selection of
