Low-E Coatings
Thaum tshav kub kub los yog lub teeb ci ntub los ntawm iav, nws yog los ntawm kev tsiv tawm los ntawm huab cua los yog reradiated los ntawm lub iav nto. Lub peev xwm ntawm cov khoom siv hluav taws xob lub zog yog hu ua nws cov emissivity. Tag nrho cov ntaub ntawv, nrog rau lub qhov rais, cov hluav taws xob (lossis hluav taws xob) cua sov hauv daim ntawv ntev-nthwv dej, lub hwj chim ntawm lub vov sab hauv ntawm lawv qhov kub thiab txias. Qhov no tso tawm ntawm cov hluav taws xob kub yog ib qho tseem ceeb ntawm cov cua sov hloov rau lub qhov rais. txo lub qhov rais ua tus tshaj tawm muaj peev xwm ua kom zoo dua nws cov khoom siv insulating.
Txheem lub iav muaj ib qho ntawm kev tshaj li ntawm 0.84 ntawm qhov ntev-nthwv ntawm cov spectrum, txhais tau tias nws emits 84% ntawm lub zog ua tau rau ib yam khoom ntawm nws qhov kub thiab txias.Nws kuj txhais tau tias 84% ntawm cov duab hluav taws xob ntev ntev tawm qhov ntawm cov iav yog absorbed thiab tsuas yog 16% yog reflected.Kuv compari-yob, EB coatings low-E yuav muaj ib qho emittance li tsawg li 0.04.Cov glazing yuav emit tsuas 4% ntawm lub zog tau ntawm nws qhov kub, thiab li no reflect 96 % ntawm qhov xwm txheej ntev-nthwv dej, hluav taws xob hluav taws xob
-tsawg manufacturers cov ntaub ntawv cov khoom yuav tsis teev cov kev cai tawm suab.Yog li, cov nyhuv ntawm E-txheej txheej tsawg kawg yog muab tso rau hauv U-factor rau hauv tsev los yog kev sib koom tes glazing.
Lub hnub ci pom kev ntawm cov low-E coatings tuaj yeem siv tau nrog rau tej qhov chaw ntawm qhov pom thiab infrared spectrum.Qhov no yog lub hauv paus ntawm lub sij hawm spectrally xim coatings, uas xaiv cov feem ntawm lub zog spectrum, yog li ntawd txaus nyiam wavelengths ntawm lub zog thiab lwm tus neeg uas tau paub txog.Ib glazing khoom ces yuav tsim los ua kom muaj zog txaus rau cov hluav taws xob kub hnub ci, hnub ci, thiab cua txias.
