Pedyo-infrared absorptioning materials inosanganisa yakakwira inoonekwa mwenje kujeka nekunyura kwakasimba kwekusarudza pakatarisana nechiedza che infrared.Semuyenzaniso, nekuishandisa kumidziyo yemahwindo, simba remaranzi ari pedyo-infrared ari muchiedza chezuva anochekwa zvakanaka achichengetedza kupenya kwakakwana, zvichikonzera mhedzisiro inodzvinyirira zvakanyanya kukwira kwekushisa mumba.

Chiedza chezuva chine ultraviolet rays (UVC: ~290 nm, UVB:290 kusvika 320 nm, UVA:320 kusvika 380 nm), mwaranzi inooneka (380 kusvika 780 nm), pedyo infrared mwaranzi (780 kusvika 2500 nm), uye pakati-infrared. mwaranzi (2500 kusvika 4000 nm).Simba rayo reshiyo i7% yemaranzi eultraviolet, 47% yemwaranzi inooneka, uye 46% yepedyo-uye yepakati-infrared mwaranzi.Pedyo-infrared mwaranzi (inotevera yakapfupikiswa seNIR) ine yakakwira mwaranzi kusimba papfupi wavelengths, uye inopinda mukati meganda uye ine yakanyanya kupisa-inogadzira mhedzisiro, saka inonziwo "kupisa kwemwaranzi."

Girazi rinotora kupisa kana kupisa rinoratidza girazi rinowanzo shandiswa kudzivirira girazi rehwindo kubva kumwaranzi yezuva.Girazi rinopinza kupisa rinogadzirwa neNIR-kutorwa kwesimbi (Fe) zvikamu, nezvimwewo zvakakanyiwa mugirazi, uye zvinogona kugadzirwa zvisingadhure.Nekudaro, kujeka kwechiedza kunoonekwa hakugone kuvimbiswa zvakakwana nekuti ine toni yeruvara yakasarudzika kune icho chinhu.Girazi rinoratidza kupisa, kune rumwe rutivi, rinoedza kuratidza simba remwaranzi yezuva nekugadzira simbi nesimbi okisidhi pagirazi.Nekudaro, iwo anoratidzwa mawavelengths anoenda kuchiedza chinooneka, izvo zvinokonzeresa kupenya muchitarisiko uye kukanganiswa kweredhiyo.Kupararira kwemakondukita akajeka akadai seyepamusoro-soro anodzivirira chiedza chezuva maITO uye maATO ane chiedza chepamusoro chinooneka uye pasina redhiyo inovhiringika mumakemikari anonzi nano-fine zvinopa chimiro chakajeka sezvakaratidzwa muFig. 1, uye pedyo-IR selective absorption membranes ine redhiyo wave transparency.

Mhedzisiro yechiedza chezuva inoratidzwa muhuwandu maererano neiyo solar radiation heat yekuwana chiyero (chikamu chesimba rezuva rezuva rinoyerera nemugirazi) kana solar radiation shielding factor yakajairwa ne3 mm gobvu girazi rakajeka.
