Many consumers are asking why air conditioning is also on in summer and why other people's electricity bills are not so high? Heating is on in winter, the electricity charge of other people's home is not so high? Why are other people's air conditioning brands so fast? Well, for these problems, in addition to the electrical factors, it is necessary to talk about the loss of aluminum alloy doors and windows.
Windows and doors waste energy in summer, which causes air conditioning to waste electricity astonishingly
The causes of energy consumption of aluminum alloy doors and windows are as follows:
I. heat transfer coefficient of aluminum alloy doors and windows
Heat transfer coefficient refers to the heat transfer per unit area of doors and windows in a certain period of time. If the heat transfer coefficient is larger, the heat loss through doors and windows in winter will be greater.
Air tightness of aluminum alloy doors and windows
Air tightness mainly refers to the ability to prevent air penetration in the state of closed doors and windows. The air tightness level can directly affect the indoor heat loss and the influence of outdoor temperature on room temperature. The higher the air tightness grade of door and window products is, the less indoor heat loss can be ensured, and the less influence of relative outdoor temperature on indoor temperature is.
3. Window to wall ratio coefficient and orientation
Generally, the resistance of energy transfer through doors and windows is much smaller than that of walls. Therefore, the indoor cold and heat consumption increases with the increase of the area ratio of doors and windows to walls. As an important measure of energy saving, doors and windows with appropriate area ratio should be selected under the conditions of indoor lighting and ventilation.
4. Choose aluminum alloy energy-saving window type
The window type is the primary factor that affects the indoor energy-saving performance. Relatively speaking, the energy saving effect of aluminum alloy sliding window is worse than that of aluminum alloy casement window.
