先量好窗戶的大致尺寸，做到胸中有數(shù)。市場上銷售的窗戶均是負責安裝的，有些不法商家測量時會虛報尺寸，以賺取更多利潤。鋁合金門窗加工設備貨比三家，任何時候購買東西都不要忘了貨比三家，貨比三家不光在于比較價格，多看多問有利于自己鑒別產(chǎn)品質量。
Take the amount of roughly the size of the window, do know what. Windows sold on the market are responsible for the installation, some illegal businesses will be measured in false size, in order to earn more profits. Aluminum alloy doors and windows processing equipment, goods than three, at any time to buy things, do not forget the goods than three, more than three goods, not only in comparison prices, more see more, ask themselves to identify the quality of products.
傳熱系數(shù)K反映玻璃溫差傳熱特性，實木門通常以櫻桃木、黑胡桃木、花梨木、沙貝利為主要材質有柚木、黑檀木.中空玻璃失效的直接原因：間隔層內(nèi)露點上升。

The heat transfer coefficient of K reflects the glass temperature difference of heat transfer, solid wood door usually with cherry, black walnut, rosewood, Sabelli as the main material of teak, ebony. The direct cause of failure: the hollow glass spacer layer in the rise of dew.

鋁合金門窗加工設備當環(huán)境溫度降低到使玻璃表面的溫度低于間隔層內(nèi)的露點時，間隔層內(nèi)的水汽便在玻璃內(nèi)表面產(chǎn)生結露或結霜（玻璃內(nèi)表面溫度高于0℃時結露,低于0℃時結霜）。
Aluminum Alloy doors and windows processing equipment when the ambient temperature is reduced to the glass surface temperature is lower than the dew point within the spacer layer, spacer layer in the water vapor in the inner surface of the glass to produce dew or frost (in the glass surface temperature is higher than 0 DEG C below 0 DEG C when the dew, frost).
有效地降低了從門窗傳導進入室內(nèi)的熱量；帶有隔熱條的型材內(nèi)表面溫度與室內(nèi)溫度接近，地降低了室內(nèi)水分由于過度飽和而冷凝在門窗表面的可能性；在冬季的寒冷天氣里，帶有隔熱條的斷橋鋁門窗框，至少能夠減少1/3的通過門窗框而散失的熱量；而在炎炎夏季，帶有隔熱條的門窗框能夠地阻擋來自室外的炙熱氣流，如果有空調，也相對地減少了空調能量的損耗，同時減少了由于空調和暖氣產(chǎn)生的環(huán)境輻射，鋁合金門窗加工設備真正地節(jié)能環(huán)保人體與環(huán)境交換熱量取決于室內(nèi)空氣的溫度、空氣流動速度和室外空氣溫度。
To effectively reduce the heat into the room from the window with a heat conduction; profiles in surface temperature and indoor temperature to minimize indoor moisture due to excessive saturated and condensed in the possibility of doors and windows surface; in the winter cold weather, with the broken bridge insulation aluminum door and window frame, at least to reduce 1/3 through the window frame and the heat loss; and in the summer heat, with a heat insulation window frame to maximize the hot air coming from outside the barrier, if there is air conditioning, reduced loss of air conditioning energy, simultaneously reducing the radiation generated by the air conditioning and heating environment, Aluminum Alloy truly energy-saving doors and windows processing equipment environmental protection of the human body and the environment depends on the heat exchange between the indoor air temperature, air velocity and outdoor air temperature.
中空玻璃的邊部密封情況：一方面，如果中空玻璃的邊部密封不好，則水氣通過密封膠層進入中空玻璃內(nèi)部的比例應以增大，中空玻璃壽命就會減少；另一方面，如果中空玻璃的邊部材料的導熱性能好，那么通過中空玻璃的隔熱系數(shù)就會提高，隔熱性能就會下降。
The edge of the hollow glass sealing situation: on the one hand, if the edge of the insulating glass seal is not good, then the water vapor through the sealing glue into the hollow glass internal ratio should be increased, the life of hollow glass will be reduced; on the other hand, if the thermal conductivity of the edge of the hollow glass material, then through the insulation coefficient will be hollow glass improved insulation performance will decline.
玻璃的熱透率：中空玻璃的傳熱主要以輻射傳熱的方式進行，如果采用高透過率低反射率的普通透明玻璃，則中空玻璃的隔熱性能，較采用高反射低透過的鍍膜或ＬＯＷ－Ｅ玻璃的低許多。
Glass thermal transmittance: heat insulating glass mainly with radiation heat transfer mode, if the high transmittance of ordinary transparent glass low reflectivity, while the heat insulation performance of hollow glass, many low high low reflection coating through LOW or E glass.
