Kusvika parizvino pakanga pasina chinyorwa chakadai chinotaura nenzira iri nyore uye pfupi kuti ndeapi magirazi okufanira kusarudza kumawindo nemadhoo. Muchagamuchira mhinduro chaiyo uye tsananguro, yakanyorwa kuti ive inonzwisisika kumunhu wese. Chinyorwa chingakuchengetedzai mari yakawanda, asiwo kutyora zvitendero zvinotonga pakati pe 95% vanhu.
Glasi rinotora nzvimbo huru yehwindo (kuvhura). Sezvo zvakakosha sezvazvakaita kuti mapepa emapuranga anonamirwa pamwechete, zvakakoshawo kuti girazi risabudise kupisa kubva mukamuri munguva yechando, uye kutonhora muzhizha.
Mufananidzo 1 – Ug uye g zvinhu
Saka pane zvinhu zviviri zvinotsanangura zvakakosha izvi:
Ug factor inoratidza kurasikirwa kwekupisa (simba) kubva mukamuri. Kana paine kamuri inodziiswa muchando, chinhu ichi chicharatidza kuti kupisa kwakadini kunopfuura negirazi kuchibuda kunze.
Nehunyanzvi: Ug - coefficient yekupfuura kupisa, inoratidzwa maererano ne standard EN-673, ine chikamu W/m2K . Kana U-value yakaderera, ndiko kuri nani kugona kwekuisa kupisa.
G factor ndiyo kupinda kwekupisa muimba. Kusiyana nechitange chekutanga, kana muzhizha tine imba ine air conditioning, chinhu ichi chinoratidza kuti kupisa kwakawanda sei kunopfuura negirazi.
Nehunyanzvi: g - kupinda kwese kwesimba rezuva kuburikidza negirazi. Rinoratidzwa maererano neshoko reEN-410. Kukosha kwariri kwakaderera, kudziya kwemukati kunowedzera kushoma.
Handei zvakarongeka.
Magirazi egirazi rimwechete.
Somuenzaniso, muzhizha, kana tembiricha iri kubva pa35o kusvika pa40o, girazi rinopisa rinotamisa kupisa kwaro kupinda mumba. Kana girazi iri rimwe chete (ngatitii rakakora 3mm), richafambisa 100% yezvarinopisa kusvika nazvo. Pano pakarepo tinofanira kusimbisa mashoko aya ekuti „yezvarinopisa kusvika nazvo“ uye titaure kuti kana kunze kuri, somuenzaniso, 40 madhigirii, hazvirevi kuti mukati munofanirawo kuva 40 madhigirii, asi zvinenge zvakaenzana nekupisa kunokwanisa kuwanikwa negirazi pacharo (mufananidzo 2), nokuti rinenge richiburitsa kupisa ikoko (kuchava, kana riri rimwe chete, 100% yekupisa kwarakapiwa). Izvi zvakangofanana nokuti mukamuri tine mudziyo wekudziya une nzvimbo yakaita segirazi. Iyi ndiyo nyaya yekupfuura kwekupisa kubva kunze kuenda mukati (G factor).
Mufananidzo 2 - Tembiricha yegirazi pa 0tembiricha yekunze uye 20tembiricha yemukati
Kana zvasvika pakufamba kwesimba kubva mukati kuenda kunze (Ug factor), kana iri girazi rimwechete rinenge 83% yesimba. Kureva kuti, 83% mukutonhora (zhizha) inorasika kunze.
Iye zvino tasvika kune iyo Ug coefficient chaizvo. Pagirazi rerudzi urwu, vanhu vakabva vati Ug yavo 5,3 kusvika 5,8. Aya ndiwo macoefficients anoratidzwa segirazi conductivity coefficients.
Tine rudzi urwu rwegirazi padzimba dzekare. Tichifunga kuti kurasikirwa kwesimba uku kwakanyanyisa, mahwindo maviri-glazed akaitwa (mapapiro maviri akaparadzana, rimwe shure kweimwe) uye tichine mahwindo akadaro nhasi pane dzimwe dzimba uye zvivako (picture 3). Zvino danho rinotevera rekuvandudza rakaitwa, iro…
Mufananidzo 3 – mhando dzekare dzemawindo ane mapapiro maviri
**Magirazi maviri (kaviri) girazi **
Girazi rinonyatsogadzirwa nemagirazi maviri, uye pakati pawo pakaumbwa eg.16mm (4+16+4).
Mufananidzo 4 - Matanda maviri egirazi ane ukobvu hwe4mm, anopatsanurwa nelista re16mm
Yekutanga uye yekupedzisira kukosha “4” inoratidza ukobvu hwegirazi hwe 4mm, uye kukosha kwepakati “16” kunoratidza ukobvu hwekuumbwa kuri pakati pavo. Ukobvu hwekuumba hunogona kusiyana kubva pa 6mm kusvika 24mm, asi chinhambwe chinopa mhedzisiro yakanaka uye apo mhedzisiro yacho iri nani chinhambwe (chekuumbwa) kubva 12-16mm. Sezvakangoita kuumbwa kubva ku 6,8,9, mm hakuna kunaka, saka izvi kubva 22, 24mm hazvina kunaka kana (isu mukambani taizoti “vanotyora zvakafanana”).
Zvatave kuziva zvinorehwa nezita reumwe neumwe, inguva yakafanira yekupa tafura yatinokwanisa kutevera.

Tafura 1 - Maitiro eUg uye g factor, pamwe nekupindirana kwechiedza
Tinoona kuti mushure mekuwedzera imwe layer yegirazi pachinzvimbo cheUg kukosha kwe 5.3, tawana kuvandudzwa ku 2.8. Kureva kuti, pachinzvimbo chekuti 100% kupisa kuchibuda muchando, unowana kuvandudzwa kwe 56%, uye 77% kupisa kunopinda muzhizha. Saka tawana kuvandudzwa kukuru nekuwedzera girazi rimwe chete.
Mhedziso ine musoro inobva yabuda, “Wobva wawedzera imwe girazi (magirazi matatu-matatu) uye isu tichawana zvakatonaka zvabuda!”, asi hazvina kudaro.
Kune humwe hutano hwakanaka hunosanganisira kupisa / kutonhora maitiro, chiedza chezuva, nezvimwewo uye tichaona kuti kubva panguva ino, kuwedzera imwe girasi kune yatove iripo maviri-layer inogona kungova kufamba kwekutengesa, iyo mutengi anofanira kungobhadhara zvakanaka.
Kuwedzera kune imwe girasi pane girazi-layer girazi, panguva ino, argon inosanganiswawo munyaya, iyo inokurudzirwa zvikuru nevanhu vanobata nekutengesa mumakambani. Tinotaura zvakawanda, hongu kune zvikonzero zvekurumbidza, asi zvirokwazvo kwete zvakanyanya sezvakataurwa uye zvikonzero zvakataurwa hazvisi zvechokwadi zvachose. Mutafura tinogona kuona kuti kana argon yakaiswa muyakajairwa kaviri-layered girazi ine Ug kukosha kwe 2.8, iyo Ug kukosha kwe 2.6 inowanikwa. Iko kuvandudzwa kudiki kwe 0.2 kunobhadharwa zvakanyanya kupfuura kuvandudzwa chaiko kunowanikwa. Kuvandudzwa uku kwakangonaka mune dzimwe nguva, uye tichatsanangura kuti gare gare.
Ehe, isu tinonyora zvese izvi uye tinozvibatanidza nekaviri-layer girazi, nekuti ine zvakawanda “zvakasiyana padingindira”. Ngatitorei muenzaniso wekuuya kuchitoro chegirazi:
Iwe: Masikati akanaka
Muvezi wegirazi: Masikati akanaka
Iwe: Ndinoda imwe izo girazi, low-emission uye rakazadzwa neargon
Mugirazi: Inogona
Muvezi wegirazi haana kukunyeperai. Makawana girazi rekudzivirira kupisa rakaderera-emission (LOW-E), rakazadzwa neargon, asi haana kukuudzai kuti iri ifirimu rakaomarara. Pagirazi iri tinowana Ug-1.8 uye kana razadzwa neargon 1.6. Uye munoona here mutafura kuti ndezvipi zviyero zvegirazi re low-emission rine firimu rakapfava (4+16+4 LOW-E MEKI FILM). Iro kukosha, kunyange pasina argon, ndiUg-1.3, rinova nani kupfuura firimu rakaomarara rine argon, uye mutengo wacho wakaderera. Kana girazi iri rikazadzwa zvakare neargon, tinowana Ug-1.1. Ipapo ndipo patinosvika panzvimbo apo argon ine basa guru. Kukosha uku kweUg-1.1 ndiko kunodiwa mumitemo mizhinji yeWestern Europe inobata nekugadzirisa nzvimbo iyi, uko girazi rinounzwa mukati memiganhu yezvinotenderwa uye semhaka iyoyo rinogona kushandiswa muindasitiri yekuvaka. Saka, argon haizadzwi zvakanyanya nekuda kwekudzivirira kupisa, sezvinofungwa nevakawanda, asi nekuti argon igasi risina divi - harisi rinoparadza semhepo. Firimu rinoiswa mukati megirazi (pakati pematanho maviri) rinobva paaluminium oxide uye kana nzvimbo iyoyo isina kuzadzwa neargon, rinongodyiwa nekufamba kwenguva nemhepo yakajairika ropera, uye ipapo kudzivirira kupisa nezvinokosha zvacho zvataive nazvo pakutanga zvinorasika.
Uyewo, kune vamiririri avo, senharo yekusawedzera argon, vanotaura chokwadi chokuti argon “inobuda” kubva mugirazi nekufamba kwenguva, i.e. inonyangarika uye tinobhadhara argon kuzadza pasina. Izvi ndezvechokwadi, asi zvishoma. Kuwanda kwekurasikirwa kweargon kunoenderana nemugadziri wegirazi, saka nekuda kwekubatirana iwe unofanirwa kusarudza makambani ane chitupa chekuti argon kurasikirwa haisi yakakura kupfuura 3% ye 10 makore. Izvi zvinoreva kuti mumakore 10 hatisi kuzorasikirwa zvinopfuura 3% zve argon, uye kurasikirwa uku hakuna basa uye mumamiriro ezvinhu chaiwo, argon inodarika girazi.
Kune zvakare akasiyana apo magirazi anozadzwa nekrypton, asi izvi zvinoitwa kana zvichidikanwa kuwana zvirinani zvekuisa mukati nemagirazi matete, asi hauzove musoro wedu izvozvi.
Tichatarisa kusanganiswa kwegirazi uku. Saka 4+16+4 LOW-E MEKI FILM. Kukosha kwayo kuri Ug-1.1. Izvi zvinoreva kuti muchando 22% yekupisa inobuda kunze, panzvimbo peiyo 56%, asi muchirimo 63% yekupisa inopinda mukati. Kuvandudzika kukuru kana tichienzanisa negirazi rekuisa rakajairika, asi kufamba kudiki kana tichienzanisa neg factor.
Mitemo iri pano inonyanya kuenderana neUg value, iyo inoreva kurasikirwa nekupisa munguva yechando, asi vanhu zvechokwadi vanoda kunyaradzwa kwekushandisa muzhizha, uko vasingade kupisa kunopinda mukamuri. Naizvozvo, SOLAR 4+16+4 FLOT yakagadzirwa, apo hunhu hwakaramba hwakafanana ne 4+16+4 LOW-E SOFT FILM mukamuri yekupisa, asi yakaderedzwa mukamuri yekupisa. 42%. Uyu ndiwo muganho wakaderera mudura remagirazi akajeka. Zvimwe zvese zvinodzikiswa uye kuvandudzwa kweUg uye g zvinhu zvinotanga kuratidzwa mukujeka kwegirazi (inozivikanwawo segirazi risina kunyorwa). Musanganiswa uyu ndiwo musanganiswa wemhando yepamusoro wemagirazi anoonekera, nenyaya yekuti tichine magirazi maviri akaturikidzana.
Magirazi matatu-matatu
Tiri kusvika pakuguma zvishoma nezvishoma, uye haasi kuzotsigira muvakidzani akapfuma anoti, “Ndinoisa mahwindo anodhura zvikuru katatu-glazed paimba yangu. Hazvina nani kupfuura izvozvo.”
Mufananidzo 5 - Muenzaniso wehwindo rine girazi rematanda matatu
Ngatidzokerei ku_tafura 1_ uye titarise kukosha kune girazi rine matatu marayer. Izvi ndizvo Ug-1.8 uye g-1.7, uye pagirazi rine marayer maviri takawana 1.3 ne 1.1 tichishandisa mari shoma zvikuru, nokuti girazi rakadaro rakachipa zvikuru kupfuura rine marayer matatu.
Chii chatakaita nekupenya katatu? Takaita kuti hwindo/gonhi rinyanye kuoma, takakwidza mutengo…..uye tikaita chigadzirwa chakaipisisa.
Mira. Ko firimu rakapfava, argon, nezvimwe zvinogona kuwedzerwa pano zvakare?
Inogona. Kana tikatora4+16Argon+4+16+4LOW-E. Muchiitiko ichi tichawana Ug-0,8uye g factor inenge yakafanana60%(hapana chino shamisira).

Mhedziso:
Kana wakanyatso verenga chinyorwa chapfuura ukatevera tafura yezvinhu zvakakosha padivi nepadivi, mhedziso inenge yatojeka pane imwe nzvimbo, maererano nenyaya yese yemagirazi.
Girazi rekuvhenekera rakaderedzwa remaviri matanda, rine firimu rakapfava, rakazadzwa neargon igadziriro iri nani, uye yakachipa zvikuru, kupfuura girazi rakajairika rine marayer matatu. Chimwe chabatsiro ndechekrwendo rakareruka, uko hupenyu hwehwindo hunowedzerwa.
Chokwadi ichi chinokonzeresa kusava nechokwadi pakati pevanhu pakutanga, uye avo vasinganzwisise tekinoroji yekugadzira magirazi (uye vachiri kunzwisisa zvese), vanowira nyore kutaura kunotapira kwevanhu vane basa rekudzikisa stock list.
Hongu, asi kunewo magirazi ane matatu-layer ane imwe musanganiswa anopa maitiro ari nani pane 4+16+4LOW-E SOFT FILM!?
Hongu, zviripo. Ivo varipo, asi mutengo wavo wakakwira zvisingaenzaniswi pane izvo magirazi akadaro anogona kupa, uye ndiyo poindi. Tingati mumamiriro ezvinhu akadaro mutengo wegirazi (pa m2) unowedzera zvakanyanya maererano nehutano hwakawanikwa.
Tora 4+16+4LOW-E SOFT FILM!
P.S.
Unogona kushamiswa nechokwadi:
Hauzokwanisi kuzvitarisa wega kuti girazi ripi raunayo! Pane girazi rinoongorora rinogona kuona kana iwe uine girazi rakapetwa kaviri kana rimwe girazi rekutanga rine firimu, asi rinodhura mashoma / zviuru zveeuro. Pane nzira inogona kuitwa murabhoritari, asi ndiani mumwe anotanga kuendesa hwindo kurabhoritari, obhadhara mutengo webvunzo, uye ozoriisa paimba kana mufurati.
Tichazvidzivirira nekusarudza kambani yakaratidza uye inozivikanwa yatinoshanda nayo, nokuti haibhadhara kutamba nechivimbo. Hazvina kufanira kuti mapurisa ekuvaka muAustria aite kuti ibvise mahwindo kubva muzvivako kana kushandura iyo yakatogadzirwa system yekugadzira nekuisa.
