Musiyano uripo pakati pesirivheri imwe, sirivha kaviri uye sirivha katatu Low-E girazi

1. Pfungwa yegirazi yeLow-E

Girazi reLow-E, rinozivikanwawo segirazi-rakadzika-emissivity girazi (Low Emissivity Glass), chigadzirwa chemufirimu chinoumbwa nemateru akawanda esimbi kana mamwe makomisheni akaputirwa pamusoro pegirazi.Iyo huru inoshanda dhizaini yeLow-E firimu ndiyo sirivheri.Sirivha chimwe chezvinhu zvine hunyoro hwakadzikira muzvisikwa.Kupfekedza nano-level sirivha layer pamusoro pegirazi kunogona kuderedza kubuda kwegirazi kubva 0.84 kusvika 0.02 ~ 0.12.Sefa chiedza chezuva muchiedza chinotonhorera.Iyo yekuputira layer ine hunhu hwekufambiswa kwepamusoro kwechiedza chinooneka uye kutarisisa kwepakati uye kure-infrared mwaranzi, nekudaro kusefa kwezuva mune inotonhora mwenje sosi, iyo isingaite chete zvinosangana nezvinodiwa zvekuvhenekesa kwechisikigo, asi zvakare inovimbisa tembiricha yekamuri yakanaka. .

2. Musiyano pakati pega, kaviri uye katatu sirivha Low-E girazi

1. Musiyano pakati pezvikamu zvefirimu

General Low-E girazi rine chete chidimbu chesirivheri yakachena (inoshanda layer), iyo inonzi imwe sirivheri Low-E girazi.Nhamba yose yezvikamu zvemafirimu egirazi-sirivheri yegirazi inopfuura 9, kusanganisira zvidimbu zviviri zvesirivha yakachena;katatu-silver Low-E girazi rine anopfuura gumi nematatu akaturikidzana efirimu, kusanganisira matatu akaturikidzana esirivheri yakachena (sezvinoratidzwa muMufananidzo 1).Kuenzaniswa negirazi rimwe-silver Low-E girazi, kunyangwe izvo zvinodikanwa zvekugadzirisa zvekaviri- uye katatu-silver Low-E girazi zvakakwirira, kushanda kwayo kwekuchengetedza simba kuri nani kupfuura kwegirazi rimwe-silver Low-E girazi.

2. Kusiyana mukushanda

Optical parameters: Pachimiro cheiyo yakafanana mwenje transmittance, kaviri sirivheri uye katatu sirivha Yepasi-E girazi ine yakaderera shading coefficient Sc uye kupisa kwekufambisa coefficient U (ona tafura iri pazasi), sirivha yakapetwa kaviri uye katatu girazi rezasi-E girazi rakaderera pane. Sirivha imwe yakaderera-E girazi inogona kuvharira yakawanda solar radiation kupisa simba uye kuwedzera kusefa kwechiedza chezuva mune inotonhora magetsi masosi.

Kunyaradza kwemukati: Yakadzika-E girazi inogona kuderedza zvakanyanya kuchinjana kwekupisa kuburikidza negirazi mukati memukati nekunze nharaunda, saka kana air conditioner iri kutonhora kana kupisa, mushure mekunge tembiricha yemukati yasvika pakudziya kwakaiswa, air conditioner inogona kunge yakamirira. nguva yakareba, nokudaro kuchengetedza kushandiswa kwesimba.Kwete izvozvo chete, maitiro emumvuri weLow-E girazi anoderedza zvakanyanya nguva yekushandisa maketeni kune mumvuri, nekudaro kunatsiridza mwenje wemukati kunyaradza uye kugadzira nzvimbo yakajeka uye yakajeka yemukati.Kuita muenzaniso wakapfava, muzhizha, inobudirira yekushanda nguva yemhepo yekufefetera uye firiji mazuva zana ezvivakwa zvine girazi rakajairwa, uye inobudirira yekushanda nguva yefiriji inopfupikiswa kusvika mazuva makumi matatu nemashanu mushure mekushandisa imwe sirivheri Low-E girazi.Kana katatu sirivheri Low-E girazi, zvinongotora anenge 30 mazuva kana zvishoma, kuwedzera kuchengetedza magetsi mabhiri.Mukufamba kwenguva, kunyangwe kushandiswa kweraviri uye katatu sirivha Yepasi-E girazi kunowedzera mutengo wekuvaka wepurojekiti, inoderedza zvakanyanya mutengo wekushandisa simba muchivako panguva yayo yekushandisa, uye iyo gare gare simba rekushandisa rinogona kudzoserwa mune imwe nguva. nguva pfupi.mari yakawedzerwa.

Zvakanakira katatu sirivheri Low-E girazi ndezvekuti inooneka mwenje transmittance yakakwirira kupfuura yekare, izvo zvinogona kuita kuti mukamuri ive nechiedza chezuva chakakwana;iyo solar infrared heat transmittance yakadzikira, uye iyo yekutamisa coefficient yakaderera zvakare, inogona kunyatso kupisa kupisa.

Musimba rose remwaranzi yezuva, mwenje unooneka unosvika 47%, uye infrared light account inosvika 51%.Chiedza chinooneka chinogona kukanganisa maitiro emeso emunhu, uye infrared inogona kuendesa kupisa simba.Ichi chikamu chesimba rekupisa regirazi re infrared yechiedza chezuva chinoita kuti tembiricha yemukati ikwire, basa rekugadzirisa mhepo rinowedzera, uye magetsi anopedzwa.Kugovewa kwesimba rekupisa kwesimba rinofambiswa nechiedza chezuva riri muwavelength renji ye780-2500 microns (nzvimbo iri kurudyi rwemutsara wakatwasuka mumufananidzo), uye chikamu chechikamu ichi chesimba rinopfuudzwa kuburikidza negirazi rinogona. kuyerwa ne "total transmittance ye solar infrared heat energy". .

Sirivha katatu Low-E ine yakaderera kwazvo "yakazara kufambiswa kwesolar infrared kupisa simba", uye kupisa kwezuva kunopfuura nesirivheri katatu Low-E ingori 15% yeiyo yesirivheri imwe Low-E, saka kupisa kwekushisa kwe. sirivha katatu Low-E girazi Mhedzisiro yacho inonyanya kuoneka.
Rutivi rworuboshwe rwemutsara wakatwasuka mumufananidzo ndiyo inoonekwa nzvimbo yechiedza, uye mwero wegonhi munzvimbo iyi unoratidza kupenya kwegirazi.Kurudyi kune infrared region, uye nzvimbo iri pasi pe curve inoratidza simba rekupisa rinofambiswa nezuva.Iyo single-silver Low-E ine nzvimbo hombe (chete Low-E inofananidzwa), inoteverwa nekaviri-silver, uye katatu-silver Low-E ine diki nzvimbo, saka iyo thermal insulation performance ndiyo yakanyanya kunaka.

Iwo magirazi maparameter anoenderana nemufananidzo uri pamusoro ndeaya anotevera:

Hollow type Chiyedza transmittance (%) Shading coefficient Sc Total transmittance ye solar infrared heat (%)
Sirivha Imwe 65 0.55 30
Kaviri Sirivha 63 0.40 12
Katatu Sirivha 65 0.33 4

Kubva kuSc chete, kukosha kwekatatu-silver Low-E haina kuderera kupfuura iyo ye-double-silver, nokuti simba rinooneka rechiedza muSc rinotora zvakawanda kupfuura infrared heat energy.Nekudaro, kubva pa "total transmittance of solar infrared thermal energy", iro solar rinopisa simba richipfuura nekatatu-silver Low-E i4%, nepo solar kupisa simba richipfuura nekaviri-silver Low-E iri 12%, iyo musiyano pakati pezviviri ndeye 3 nguva.Iko kupisa kwekupisa uye simba rekuchengetedza simba resirivheri katatu Low-E iri nani kupfuura iyo yesirivha yakapetwa kaviri.Kushandiswa kwekatatu sirivha yakaderera-E girazi kunogona kunyatso kudzikisa kushandiswa kwesimba kunokonzerwa nemukati memhepo yekufemesa.
