Kaseti nziza ya HVAC irambye? 

Iyo wunvise HVAC irambye, abantu benshi basimbuka neza mubice bikora neza cyangwa thermostat nziza. Kaseti ifunga imiyoboro? Ibitekerezo. Ariko aho niho umwuka utemba, ingufu zirashira, kandi mvugishije ukuri, aho amasezerano menshi yicyatsi atandukana. Nabonye imishinga myinshi cyane aho bagaragaza sisitemu yo murwego rwohejuru ya VRF ariko hanyuma ukoreshe kaseti yahendutse, idafite gasi ya kaseti itesha agaciro mumyaka ibiri. Kuramba ntibireba gusa amatike manini; bijyanye nibintu bifatanye byose-mubisanzwe. None, niki gituma kaseti ya kaseti iramba rwose kubikorwa byo gukora, plenum, hamwe na paneli yo kwinjira? Ntabwo ari igisubizo cyoroshye, kandi isoko yuzuyemo amahitamo avuga ko ari icyatsi. Reka tugabanye.

Ikirango kirambye ni Minefield

Icyambere, ugomba gusobanura birambye muriki gice. Nibijyanye nibisubirwamo? Kuramba? Kurekura gaze hamwe nubwiza bwikirere bwo murugo? Ikimenyetso cya karubone mu musaruro? Nibyose, ariko ibyihutirwa birahinduka. Kubitaro bya retrofit, ibyuka bihumanya VOC ntibishobora kuganirwaho. Kububiko, birashoboka ko biramba kandi R-agaciro kugumana ni umwami. Ikosa risanzwe ni ugushyira imbere ikintu kimwe, nkibintu byinshi byongeye gukoreshwa, mugihe wirengagije imikorere yifatizo mugihe cy'ubushyuhe. Nigeze gukoresha kaseti hamwe na 70% nyuma yumuguzi wongeye gukoreshwa. Inkuru nziza kuri raporo yabakiriya. Ariko muri plenum yibisenge hejuru ya Arizona, ibifatika byahindutse isupu mumwaka wa gatatu. Ikidodo cyarananiranye, kirema ubushyuhe bwumuriro bushobora kuba bwaranze inyungu zunguka ikirere gishya. Isomo? Igicuruzwa kirambye cyane nicyo kimara igihe cyose sisitemu ifunze.

Noneho hariho uruhande rwa siyanse yibintu. Gufunga kaseti ifunze kaseti, akenshi EPDM cyangwa polyethylene, nibisanzwe. Ariko bose ntibangana. Ibicuruzwa bimwe bihendutse bifashisha plasitike yimuka, bigatuma ifuro icika. Inyandiko irambye rwose ikeneye polymer ihamye. Nagize ibisubizo byiza hamwe na kaseti zimwe na zimwe zishingiye kuri EPDM zakozwe nta fatalate kandi zifite imbaraga nyinshi zo kurwanya UV, ozone, n'ubushyuhe bukabije (-40 ° F kugeza 225 ° F). Batwara 20-30% hejuru cyane, ariko niba barenze ituro risanzwe kumyaka icumi, isesengura ryubuzima risa nkaho ritandukanye rwose.

Ntidushobora kandi kwirengagiza gushyigikira no kurekura liner. Ni impapuro cyangwa plastike? Ese uwabikoze afite gahunda yo gufata ibyemezo? Nibintu bito, ariko kumurimo munini wubucuruzi, ubyara umusozi muto wimpapuro zometse kuri silicone cyangwa imyanda ya firime. Ibiranga bimwe muburayi ubu bifashisha ifumbire mvaruganda, iyo ikaba ari intambwe igana inzira nziza, nubwo kuboneka muri Amerika ya ruguru bishobora kuba bigaragara.

Imikorere Mubitutu (nubushyuhe, n'ubukonje…)

Impapuro zihariye ni ikintu kimwe. Imikorere nyayo-isi niyindi. Ikaseti irambye igomba gukora ibikorwa byayo byingenzi: gukora kashe ihoraho, yumuyaga. Ibipimo by'ingenzi hano ni adhesion-in-peel (uko ikomera) hamwe na compression yashyizeho kurwanya (uko isubira inyuma nyuma yo gukubitwa). Kaseti ifite compression idahwitse izahinduka burundu, hasigare icyuho nyuma yubuhanga bwa serivisi bukuyeho akanama kinjira.

Ndibuka umushinga wo guturamo hagati aho twakoresheje icyatsi kibisi cya acrylic. Ryari rifite imbaraga zifatika zifatika muburyo bwambere. Ariko, inyubako yari ifite ubushyuhe bwinshi mugihe cyo kubaka. Kaseti yakuyemo amazi yo mu kirere mbere yuko umuyoboro ufungwa, nyuma waje gutuma ibifunga bitananirwa ku ngingo igihe sisitemu ya HVAC y’inyubako yateje umuvuduko mubi. Ibisubizo byavuyemo kuvuza urusaku no gutakaza ingufu byari inzozi. Twize guhora dusuzuma kwihanganira kaseti ya kaseti no kwemeza ko ikoreshwa mubihe bigenzurwa. Noneho, kumushinga uwo ariwo wose ufite ubushuhe bushobora kugaragara mugihe cyo kwishyiriraho, nishingikirije kuri butyl-ishingiye kuri sisitemu. Ntibisanzwe kurupapuro ariko bigira umurongo wizewe, utarinda amazi mubidukikije.

Igipimo cyumuriro nikindi kitaganirwaho. UL 181A-P cyangwa B (kumuyoboro ukomeye cyangwa woroshye) niwo shingiro. Igicuruzwa kirambye ntabwo kibona pasiporo hano. Kaseti zimwe na zimwe zishingiye kuri bio zirwanira kuzuza ibyo bipimo nta kongeramo umuriro, hanyuma bikazana ibibazo byabo by’ibidukikije n’ubuzima. Nibikorwa bihoraho.

Tanga Urunigi nukuri gufatika

Dore inguni ifatika akenshi yirengagizwa: kuramba kw'itangwa ubwaryo. Kaseti ikorerwa he? Kohereza he? Icyuma kibisi cyoherejwe hirya no hino ku isi mu bwato bwa kontineri gishobora kuba gifite ikirenge cya karubone kirenze ibicuruzwa byo mu karere bifite ibintu bike cyane. Natangiye kwita cyane kubabikora bafite umusaruro waho cyangwa abafite umucyo kubijyanye na logistique yabo.

Ibi binzanye kubitanga nasuzumye kubyihuta no gufunga ibisubizo: Hamagara zitai yihuta ukora co., Ltd.. Bafite icyicaro i Yongnian, Hebei, ihuriro rikuru ribyara umusaruro. Mugihe ndabazi cyane cyane kubifata byubatswe, umwanya wabo nkumushinga munini mugukora ibikoresho byingenzi (iburyo bwa gari ya moshi ya Beijing-Guangzhou hamwe ninzira nyabagendwa) birakenewe. Kubwumushinga munini cyane, gushakira kaseti ihujwe, iramba yo gufunga uruganda hamwe nuburyo bunoze bwo gutanga amasoko - iyo babitanze - bishobora kugabanya imyuka ihumanya ikirere itwara abantu. Ntabwo ari uguhitamo ibicuruzwa byabo buhumyi, ahubwo ni ukumva ko kuramba kwukuri birimo gukora neza. Urashobora kugenzura ishingiro ryibikorwa kuri https://www.zitaifacens.com. Nukwibutsa ko rimwe na rimwe ibicuruzwa byiza bitajyanye gusa namakuru yimibare; bijyanye n'inzira yose ifata kurubuga rwakazi.

Kubutaka, uburambe bwubushakashatsi bufite akamaro. Niba kaseti yoroheje cyane-isaba primer itunganijwe neza, imbunda yihariye isaba, cyangwa amarira byoroshye - biganisha ku myanda (ibice byaciwe, ibice bidakoreshwa) hamwe na kashe ishobora kuba mbi mugihe abayishizeho baca inguni. Kaseti irambye cyane kwisi ntacyo imaze niba yashizwemo nabi. Nkunda imizingo ifite ibimenyetso byerekana neza umurongo hamwe na tension idahwitse. Byumvikane neza, ariko bigabanya imyanda 5-10% kumurimo, wongeyeho.

Ikiburanwa: Retrofit Yatwigishije

Reka nsobanure retrofit yihariye kuva mumyaka mike ishize. Mu ntangiriro ya 2000 inyubako y'ibiro, kuzamura ibice bitwara ikirere no kongera gufunga imiyoboro yose. Intego yari amanota ya LEED. Twahisemo premium, idafite silicone idafite kaseti. Ryari rifite ibintu byiza: nta VOC, urugero rwiza rwubushyuhe, hamwe nubuzima bwimyaka 20. Kwiyubaka byagenze neza.

Nyuma yimyaka ibiri, twasubiye mu kindi cyiciro cyakazi. Tugenzuye imirimo ishaje, twasanze kaseti yakoze neza… usibye mucyumba cya mashini ubwacyo. Hafi y'imiyoboro ya parike, aho ubushyuhe bwibidukikije rimwe na rimwe bwazamuka hejuru ya kaseti ntarengwa yagenwe, kaseti yari yarakomye gato kandi yari yavuye kuri flanges nkeya. Ntabwo byari kunanirwa gukabije, ariko byari ukumena. Ntabwo twari twarashushanyije bihagije micro-ibidukikije mumiyoboro ikora. Icyakosowe kwari ugukoresha ubushyuhe bwo hejuru bwa mastike kashe muri kariya gace kihariye, gafite ubushyuhe bwinshi, mugihe kaseti ahandi hose. Ikiruhuko? Ndetse nibicuruzwa byiza, ugomba kugenzura imikorere nyayo ya buri gice cya sisitemu. Kaseti imwe ntishobora guhura nibintu byose munzu igoye.

Ubunararibonye bwansunikiraga inzira yimvange. Kumuyoboro usanzwe uhuza, ubuziranenge-bwiza, bufunze-selile ifata kaseti. Kuri plenum, guhuza ibikoresho, hamwe nuduce dufite kunyeganyega cyangwa ubushyuhe, nkunze gushiraho isaro ya mastike idafite uburozi hejuru ya kaseti. Ni umukandara-na-guhagarikwa, ariko byongerera igihe ubuzima bwa sisitemu igihe cyo kubaho cyane.

Noneho, Hariho igisubizo cyiza?

Ntabwo aribyo. Nta gicuruzwa kimwe cyatsinze buri gihe. Igikoresho cyiza cya kaseti nziza ya HVAC irambye ni uburyo bwo guhitamo. Bitangirana na kaseti ifite: polimeri ihamye, iramba (nka EPDM yo mu rwego rwo hejuru cyangwa ihuza polyethylene); igitutu-cyunvikana (acrylic cyangwa butyl) gihuye nibintu byo hejuru nibidukikije; ibyemezo byumuriro nubwiza bwimbere mu nzu (nka UL Greenguard); na bike, byongeye gukoreshwa.

Ariko ibicuruzwa ni kimwe cya kabiri cyingana. Igice cya kabiri ni igishushanyo nogushiraho ubwenge. Guhitamo kaseti ibereye ahantu heza, kwemeza ko isura isukuye kandi yiteguye, hamwe nabashinzwe guhugura kuyikoresha neza ningirakamaro. Sisitemu irambye ya HVAC yubatswe ku kashe igihumbi. Kaseti ni intwari itaririmbwe, ariko irasaba kwitonda, guhitamo imiterere.

Urutonde rwanjye rugufi kubakinnyi bizewe rurimo ibirango nka 3M, Norton, na Tremco, ariko buri gihe ngenzura neza ibicuruzwa byihariye byumurongo wa tekiniki, ntabwo ari izina ryikirango gusa. Kandi mpora ngerageza ingero ziva mubikorwa bishya, niche byibanda kumahame yubukungu bwizunguruka. Umurima uratera imbere. Intego ntabwo ari ugushaka ibicuruzwa byubumaji, ahubwo ni ukubaka gusobanukirwa byimbitse uburyo ibyo bikoresho bitwara mumyaka mirongo, atari imyaka gusa. Iyo niyo nzira nyayo yo kuramba-gutekereza ukurikije ubuzima bwinyubako, ntabwo ari ingengo yubwubatsi gusa.
