The status of energy-saving doors and Windows in energy-saving system

Building doors and Windows for the building insulation performance of the weakest status, with the continuous improvement of people's living standards, in order to create a comfortable living environment, indoor refrigeration or heating method is more and more common, doors and Windows as one of the surface envelope of the building, directly affect the building's energy saving performance, improve the insulation performance of doors and Windows is the main way to ensure building energy consumption. Now more and more people pay attention to the use of energy-saving doors and Windows in buildings.

The so-called real energy-saving system doors and Windows, not a single partition bridge aluminum profile or the use of Low-E insulating glass energy-saving materials, it is a perfect combination of a system, the comprehensive result of the performance of each link, indispensable, measuring whether the building doors and Windows energy saving should mainly consider three elements, namely, heat convection, heat conduction and heat radiation:

The loss of heat is the circulation of hot cold air through the gap of doors and Windows, and the heat exchange through gas convection leads to heat loss.

Heat conduction is the heat transfer carried out by the molecular movement of the material itself used by the door and window, which is transferred from one surface of the material itself to another surface, resulting in heat loss.

Radiation is mainly transmitted directly in the form of rays, resulting in loss of energy consumption.
