Kukhazikitsa ndi Kumanga Zipinda Zazikulu Zosungira Mafiriji

Zipinda zosungiramo zinthu zozizira kwambiri zimadalira kuyika bwino ma sandwich panel komanso ukadaulo wapamwamba wotsekera.mapulojekiti osungiramo zinthu zozizira zapakati ndi zazikulu kutentha kochepaNgati ikugwira ntchito pa −18°C kapena pansi pake, ubwino wa zomangamanga umatsimikizira mwachindunji momwe zimagwirira ntchito poteteza kutentha, kugwiritsa ntchito bwino mphamvu, komanso kulimba kwa nthawi yayitali.

Mavuto Ofunika Kwambiri Okhazikitsa Zipinda Zozizira Kwambiri

Mu zipinda zoziziritsira mafakitale, makina a sandwich panel amapanga chotchinga chachikulu cha kutentha pakati pa malo olamulidwa ndi malo akunja. Malowa amagwira ntchito kutentha kwambiri, nthawi zambiri kupitirira 40°C pakati pa momwe ntchito yomangira ndi momwe imagwirira ntchito. Chifukwa cha kusiyana kumeneku, ngakhale zolakwika zazing'ono zoyika zimatha kuyambitsa mavuto akulu pakugwira ntchito.

Vuto lalikulu loyamba limakhudza kulondola kwa kuyika. Mapanelo a polyurethane sandwich omwe amapangidwira zipinda zoziziritsira nthawi zambiri amakhala ndi miyeso yayikulu komanso kulemera kwakukulu. Mapulojekiti akuluakulu amafunika kukhazikika kosalekeza kwa mapanelo mazana ambiri a khoma ndi denga. Ngati okhazikitsa alephera kusunga malo olondola, mipata yowoneka kapena yobisika ingawonekere m'malo olumikizirana. Kupatuka kwa mapewa akapitirira 2 mm, milatho ya kutentha imakula ndikuchepetsa mphamvu yotetezera. Pakapita nthawi, kutayikira kozizira kumabweretsa kupangika kwa condensation ndi chisanu chochuluka, zomwe zimawonjezera ntchito ya compressor ndi kugwiritsa ntchito mphamvu.

Vuto lachiwiri likukhudzana ndi kukula ndi kufupika kwa kutentha. Ntchito yomanga nthawi zambiri imachitika kutentha kozungulira, pomwe mikhalidwe yogwirira ntchito imakhalabe yotsika kwambiri kuposa kuzizira. Kusiyana kwa kutentha kumeneku kumapangitsa kuti zinthu zichepe pambuyo poti zayamba kugwira ntchito. Popanda njira zoyenera zokulira, kusintha kwa ma panel kungakhudze kulimba kwa mafupa ndi kukhazikika kwa kapangidwe kake. Mainjiniya ayenera kuwerengera mosamala kulekerera mayendedwe kuti asunge magwiridwe antchito osalowa mpweya.

Vuto lachitatu limayang'ana kwambiri pa kuyika ma node. Makona, mafelemu a zitseko, malo olumikizirana pansi ndi makoma, ndi malo olowera mapaipi ndi malo ofooka otsekera. Malo osinthira awa nthawi zambiri amakhala ndi kupsinjika kwakukulu komanso chiopsezo chachikulu cha kutuluka kwa madzi. Zipinda zazikulu zoziziritsira m'mafakitale zimafuna zigawo zolimbitsa ngodya ndi njira zolumikizirana zokonzedwa bwino. Kusasamalidwa bwino m'malo awa nthawi zambiri kumabweretsa kulephera koyambirira kwa kutenthetsa komanso ndalama zambiri zokonzera.

Magulu a polojekiti omwe amazindikira mavutowa panthawi yokonzekera akhoza kupewa kusakhazikika kwa ntchito ndi kuwononga mphamvu pambuyo poyambitsa ntchito.

Kusankha Zinthu ndi Ukadaulo Woyenera Wotsekera Zipinda Zozizira Zolimba

Ubwino wa zinthuzo umakhazikitsa maziko a zipinda zoziziritsira zokhazikika. Mapanelo a sandwich a polyurethane opangidwa mwamakonda okhala ndi kachulukidwe kosachepera 40 kg/m³ komanso kutentha kofanana kapena kochepera 0.024 W/(m·K) amapereka mphamvu yolimba yotetezera kutentha.

Opanga ayenera kuchita kafukufuku wokhwima asanaperekedwe kuti atsimikizire kuti mapanelo ndi olondola komanso kuti m'mphepete mwake ndi osalala. Kupanga bwino kwa fakitale kumachepetsa kusokonekera kwa malo ogwirira ntchito. Opanga ayenera kulinganiza maziko a kapangidwe kake asanayike mapanelo ndikugwiritsa ntchito zida zaukadaulo zoyikira pamalo oyenera. Akatswiri ayenera kuyang'anira mipata yolumikizirana mkati mwa 2 mm kuti apewe kulowa kwa mpweya wozizira.

Zomatira zapadera zotsika kutentha ziyenera kusintha zomatira wamba chifukwa zipangizo wamba zimatha kusweka pamene zikuzizira. Mapangidwe olumikizira otanuka amathandiza kuyamwa kutentha ndikuletsa kupsinjika pa malo olumikizirana.

Kulimbitsa mfundo kumafuna kukonzedwa bwino. Zowonjezera za ngodya zooneka ngati L zimalimbitsa malo olumikizirana makoma ndikuwonjezera magwiridwe antchito otumizira katundu. Makomo otseguka ndi malo olowera mapaipi ayenera kugwiritsa ntchito njira ziwiri zotsekera zomwe zimaphatikiza mizere yopondereza ndi chosindikizira chosazizira. Njira yotetezera iyi yokhala ndi zigawo ziwiri imachepetsa kwambiri mwayi wotuluka. Kuphatikiza apo, okhazikitsa ayenera kuphatikiza zotchinga nthunzi ndi nembanemba zosalowa chinyezi ngati pakufunika kutero kuti apewe kusamuka kwa madzi mkati mwa zigawo zotetezera kutentha.

Kuwongolera khalidwe mosalekeza kumatsimikizira kuti zinthu zikuyenda bwino nthawi zonse. Akamaliza kulumikizana kulikonse kapena kulumikizana, akatswiri ayenera kuchita mayeso otayira mpweya nthawi yomweyo. Kuzindikira msanga kumalola kukonza mwachangu makina asanayambe kugwira ntchito. Ma sandwich panels osagwira moto amawonjezera chitetezo china mwa kuphatikiza mphamvu zotetezera kutentha ndi miyezo yabwino yotetezera moto. Zipinda zamakono zamafakitale ziyenera kukwaniritsa miyezo yonse ya mphamvu ndi malamulo achitetezo.

Magulu a polojekiti akaphatikiza zipangizo zapamwamba, kukhazikitsa molondola, komanso kutseka bwino, zipinda zosungiramo firiji zimakhala ndi kutentha kokhazikika komanso kugwiritsa ntchito mphamvu moyenera. Kapangidwe kokonzedwa bwino kamachepetsa ndalama zokonzera zinthu komanso kuteteza katundu wosungidwa pansi pa kutentha kochepa nthawi zonse.
