铝合金门窗设备维护结构特点

铝合金门窗设备厂家说：“窗户作为建筑外维护结构，其功能必须具备良好的保温、隔热、隔声性能，具有足够的气密性、水密性和抗风压强度”。现在很多房地产开发商深知众多消费者的消费心理，充分利用窗户是建筑的眼睛这一比喻，热衷宣传抄作各种材料技术，以新颖造型和醒目色彩吸引人们的眼球。
Aluminum windows and doors equipment manufacturers said: "windows as building external maintenance structure, its function must have good insulation, heat insulation, sound insulation performance, and has enough air tightness, water tightness and wind pressure resistance". Now many real estate developers know that many consumer psychology, make full use of the window is building eyes this metaphor, keen awareness of Chaozuo materials technology, to attract people's attention to the novel and eye-catching color.

按照中国建筑金属结构协会铝合金门窗委员会提供的资料表明：“铝合金门窗属于性价比比较高的产品”。首先说传热系数(K值)的性能，专家指出：“通过科学实验，三腔结构的U-PVC型材的传热系数可达到1.9W/(平米.K)，国内有些企业开发的四腔、五腔结构的U-PVC塑料窗体系，传热系数已经达到1.7W/(平米.K)。这个数字是其它材料无法比拟的”。铝合金门窗开启方式主要有推拉、外开、内开、内开上悬，新型的开启方式有推拉上悬式。

According to the information provided by the aluminum alloy doors and windows Committee of the China Architectural Metal Structure Association, "aluminum alloy doors and windows are a product with a relatively high cost performance". First, the heat transfer coefficient (K value) performance, experts pointed out: "through scientific experiments, the heat transfer coefficient of U-PVC profile three cavity structure can reach 1.9W/ (.K square meters), some domestic companies to develop four cavity, five cavity structure of U-PVC plastic window system, the heat transfer coefficient has reached 1.7W/ (.K square meters). This number is incomparable to other materials. The opening mode of aluminum alloy doors and windows mainly includes push, pull, open, inside and inside, and the new type of opening is pushed and pulled up.
一般来说，推拉窗有立面简洁、美观，使用灵活安全、使用寿命长、采光率大、占用空间少，方便带纱窗等优点。外开窗有开启面大，密封性、通风透气性、保温抗渗性能优良等优点。目前铝合金门窗主要为推拉式，其次是外开式，内开或其他开启方式在我国使用较少。铝合金门窗设备的结构无疑对其节能效果起着至关重要的作用，那么要达到良好的节能效果，就必须具备尽可能合理的结构。
Generally speaking, the push-pull window has the advantages of simple and beautiful facade, flexible and safe use, long service life, large daylighting rate, less space occupation, and convenient screen window. The open window has the advantages of large opening surface, sealing, ventilation and permeability, excellent heat preservation and anti permeability. At present, the aluminum alloy doors and windows are mainly pushed and pulled, followed by open type, and the internal opening or other opening methods are less used in our country. The structure of aluminum alloy doors and windows plays a vital role in the energy saving effect. If we want to achieve good energy saving effect, we must have the most reasonable structure.
要达到节约能源的效果，必须从热力学角度去考虑。热力学中热量的交换分为对流、传导和辐射。这三种方式当然也适用于建筑铝合金门窗及幕墙。对流是在铝合金门窗空隙间热冷气流的循环流动，导致热量交换，产生热量流失。
In order to save energy, it must be considered from the thermodynamic point of view. In thermodynamics, the exchange of heat is divided into convection, conduction and radiation. Of course, these three ways are also suitable for building aluminum alloy doors and windows and curtain walls. Convection is the circulation of heat and cold air between the gap between the aluminum alloy doors and windows, resulting in heat exchange and the loss of heat.
