关于防爆膜的太阳能总阻隔率与红外线阻隔率 (TSER & IRR)
发布时间:2012-5-30    已浏览[8344]次

TSER is an industry recognized performance value, infrared rejection is not. TSER is the percentage of all energy from the sun reflected
away from a window, as well as the percentage absorbed by the window and released back outdoors.太阳能总阻隔率是薄膜行业认可
的评估数据,红外线阻隔率并不是。太阳能总阻隔率是从汽车玻璃上发射的,吸收的和透过的太阳能之和。

There are many problems with so-called "infrared rejection", such as the fact companies selectively choose which parts of the spectrum
they report and IRR does not include absorption- an important contributor to heat gain.For instance, a certain large company reports this for only a small part of the spectrum which is less than 10% of the actual infrared wavelengths. Some other companies report this at only one wavelength! So they call it "infrared rejection", but really it is only a small part of the total infrared and is not representative of the actual infrared energy. Also, manufacturers of some products that have very high absorption report IRR because it does not count absorption against it. The TSER is the "true" heat rejecting value for a film, because it takes the entire solar spectrum into account (infrared is only 49% of the solar energy anyway), and also includes the effects of absorption. The National Fenestration Rating Council is the the only third party window rating system. It is recognized by Energy Star, utility companies, and U.S. and Canadian governments. They only recognize SHGC/TSER. They do not recognize IRR.
仅仅强调红外线阻隔率有很多的问题。例如,很多公司选择性的给出某个波段的红外线阻隔率。另外,红外线阻隔率也没有包含吸收的热能部分,而吸热部分也是热增量很重要的因素之一。某国际大公司仅仅出示红外波普的大约10%的数据。
也有其他公司报告仅一个波段的数据!所以他们称它为红外阻隔率。但事实是,它仅仅是红外线的一小部分,也不能代表整个
真实的红外线能量。还有就是,一些生产吸热薄膜的企业会使用红外阻隔率来吸引大家的眼球。太阳能阻隔率是能够实际反映薄膜隔热能力的真实数据。因为它计算了整个太阳能波谱范围。(红外线仅占到49%的太阳能波谱。)同时也包含的吸收的能量。美国国家门窗评定委员会是唯一的第三方薄膜评级机构。它的数据被包括能源之星等机构和美国,加拿大政府认可。这些机构只采用SHGZ/TSER的数据作为评判标准而不是红外线阻隔率。

In short, IRR is a misleading marketing gimmick.
简而言之,红外线阻隔率仅仅是使人误解的营销噱头而已。

SHGZ/TSER
注:太阳能得热系数 SHGZ 数值越小越好
太阳能总阻隔率 TSER 数值越大越
