Ukukhetha amaphaneli esandwich afanele afakwe umswakama kuyisinqumo esibalulekile ekwakhiweni kwesitoreji esibandayo. Izinto eziyinhloko zamaphaneli esandwich zisho ukusebenza kahle kwamandla, ukuphepha komlilo, kanye nobude besakhiwo. Abasebenzi kumele bakhethe phakathi kwe-PU, i-PIR, kanye noboya bedwala ngokusekelwe ezidingweni ezithile zokushisa nokuphepha. Uhlobo ngalunye lwamaphaneli esandwich afakwe umswakama lunikeza izinzuzo nezinselele ezihlukile zokuphathwa kwesikhungo isikhathi eside.
Ukusebenza Kokushisa kanye nokonga Amandla
Ukushisa, noma inani le-R, kunquma ukuthi iphaneli imelana kahle kangakanani nokugeleza kokushisa. Amaphaneli e-PU ne-PIR ahamba phambili emakethe ekusebenzeni kahle kokushisa. Amaphaneli esandwich e-PU afakwe umswakama ngokuvamile anikeza ukufudumala okungaba ngu-0.022 W/m·K. Lokhu kusebenza kahle okuphezulu kuvumela izindonga ezincane ngenkathi kugcinwa isimo sezulu sangaphakathi esizinzile. I-PIR iyinguquko ye-PU futhi inikeza ukuzinza okungcono kakhulu kokushisa.indawo yokugcina ebanda kakhulu, ukushintsha kusuka ekushiseni okujwayelekile kuya ku-PIR yezinga eliphezulu kunganciphisa isidingo samandla okupholisa ngo-15% kuya ku-20%. Lokhu kunciphisa kusho izinkulungwane zamaRandi ekongeni minyaka yonke kwendlu yokugcina impahla ephakathi nendawo.
Amaphaneli oboya bedwala anokushisa okuphezulu kakhulu, ngokuvamile acishe abe ngu-0.035 kuya ku-0.040 W/m·K. Ukuze ufinyelele umphumela ofanayo wokushisa njengephaneli ye-PIR engu-100mm, uzodinga iphaneli yoboya bedwala elicishe libe ngu-180mm ubukhulu. Lobu bukhulu obengeziwe kunciphisa umthamo wokugcina wangaphakathi wesakhiwo sakho. Idatha ikhombisa ukuthi ukusebenzisa i-PIR ngaphezu koboya bedwala kungandisa isikhala sephalethi esisebenzisekayo ngo-5% kuya ku-8% endaweni efanayo yokwakha. Kumabhizinisi abeka phambili izindleko eziphansi zezinsiza kanye nobuningi besitoreji esiphezulu, i-PU ne-PIR zihlala ziyizinketho eziyinhloko. Zinciphisa umthwalo womsebenzi kuma-compressor futhi zandisa isikhathi sokuphila sohlelo lonke lokuqandisa.
Ukuphepha Komlilo kanye Nemiphumela Yomshuwalense
Ukumelana nomlilo yilapho uboya bedwala budlula khona amagwebu okwenziwa. Uboya bedwala buyinto engashi enendawo yokuncibilika engaphezu kuka-1,000°C. Ngokuvamile bufinyelela izinga lomlilo le-A1, buhlinzeka ngezinga eliphezulu lokuvikela ezindaweni ezinobungozi obukhulu. Ngokuphambene nalokho, amaphaneli e-PIR “ayavimbela umlilo.” Ayasha lapho evezwa ilangabi, okwenza ungqimba oluvikelayo olunciphisa ukusabalala komlilo. I-PIR ivame ukuhlangabezana nezindinganiso ze-B-s1, d0 ngaphansi kwezigaba zaseYurophu. NgenkathiAmaphaneli e-PUzivamile, azinawo amandla okumelana nomlilo futhi zingase zibe nomusi omningi ngesikhathi somcimbi womlilo.
Izinkampani zomshuwalense ziwathanda kakhulu amaphaneli e-rock wool kanye ne-FM-appointed PIR. Izikhungo ezisebenzisa amaphaneli e-PU ajwayelekile zivame ukubhekana namaphrimiyamu omshuwalense aphezulu ngo-20% kuya ku-30% kunalawo asebenzisa uboya be-rock. Kwezinye izifunda, abahlinzeki bomshuwalense bangase benqabe ukumboza izitolo ezibandayo ezingenazo izingqimba eziqinisekisiwe ezingamelani nomlilo. Isigameko esisodwa somlilo endaweni evikelwe yi-PU singaholela ekuweni kwesakhiwo ngokuphelele ngemizuzu embalwa. Amaphaneli e-rock wool ahlinzeka ngesivikelo somlilo esibalulekile, ngokuvamile anikeza imizuzu engama-60 kuya kweyi-120 yobuqotho bomlilo. Lokhu kuvikela kusindisa izimpilo futhi kuvimbela ukulahleka okuphelele kwempahla ebizayo kanye nempahla yesakhiwo ngesikhathi esiphuthumayo.
Ubuqotho Besakhiwo Nokumelana Nomswakama
Izindawo zokugcina ezibandayo zibhekene nokwehluka okukhulu kwezinga lokushisa okubangela ukucindezeleka ngokomzimba kumaphaneli. Amaphaneli e-PU ne-PIR anokuqina okuhle kwesakhiwo kanye nesilinganiso esiphakeme samandla nesisindo. Isakhiwo sawo samaseli avaliwe, esivame ukuba ngaphezu kuka-90%, sivimbela umhwamuko wamanzi ukuthi ungangeni enkabeni. Umswakama uyisitha sokushisa; ukwanda okungu-1% kokuqukethwe komswakama kunganciphisa inani lokushisa ngo-25%. Ngenxa yokuthi i-PIR ne-PU ziyamelana namanzi, zigcina inani lazo le-R amashumi eminyaka. Ziphinde zimelane nemithwalo esindayo yama-evaporator alenga ophahleni kanye nemishini yokupholisa ngempumelelo.
Amaphaneli oboya bedwala enziwe ngemicu yamaminerali, evulekile ngokwemvelo. Ngenkathi abakhiqizi bengeza izihlanganisi ezivimbela amanzi, uboya bedwala busengamunca umswakama uma isikhumba sensimbi sibhobozwa. Uboya bedwala obumanzi bulahlekelwa yizimfanelo zalo zokuvikela cishe ngokuphelele futhi bube nzima kakhulu. Lokhu kukhula kwesisindo kungasongela ukuphepha kwesakhiwo kwezisekelo zophahla. Kodwa-ke, uboya bedwala bunikeza ukuvikela okuphezulu kwe-acoustic, kunciphisa umsindo wegumbi lesitshalo ngama-decibel angu-30. Lokhu kuyinzuzo ebalulekile yezindawo eziseduze nezindawo zokuhlala. Abasebenzi kumele baqinisekise ukuvalwa okuphelele kwamalunga oboya bedwala ukuvimbela "umphumela weshimoni" wokufuduka komswakama.
Izindleko Zomjikelezo Wokuphila kanye Nomthelela Wezemvelo
Izindleko zesikhathi eside zephaneli zifaka phakathi intengo yokuthenga, ukulungiswa, kanye nokulahla ekugcineni. Amaphaneli e-PU avame ukuba nezindleko zokuqala eziphansi kakhulu, okwenza athandwe kumaphrojekthi aqaphela isabelomali. Kodwa-ke, amaphaneli e-PIR anikeza imbuyiselo engcono ekutshalweni kwezimali ngenxa yokuhlanganiswa kwawo kokusebenza kahle kanye namazinga omshuwalense aphansi. Esikhathini seminyaka eyi-15, ukonga amandla okuvela ku-PIR kuvame ukukhokhela igebe lentengo yokuqala ngokuphindwe kathathu. Uboya bedwala bunezindleko zokufaka eziphakeme ngenxa yesisindo salo, ngokuvamile ezidinga uhlaka lwensimbi oluqinile kanye nemishini yokuphakamisa ekhethekile.
Ukusimama sekuba yisici esibalulekile ngo-2026. Uboya bedwala bungasetshenziswa kabusha kakhulu futhi benziwe ngamatshe entaba-mlilo amaningi. Ama-foam e-PU ne-PIR kunzima ukuwasebenzisa kabusha, yize izinhlobo ezintsha ze-"bio-polyol" zingena emakethe. Lapho kubalwa umthamo wekhabhoni, uboya bedwala buthola amaphuzu amahle ekulahleni kokuphela kokuphila. Ngokuphambene nalokho, i-PIR ithola amaphuzu angcono ku-carbon esebenzayo ngoba igcina amandla amaningi ngesikhathi sokuphila kwesakhiwo. Ukukhetha iphaneli enokuqukethwe okuphezulu okusetshenziswe kabusha kungasiza indawo ukuthi ithole isitifiketi se-LEED noma se-BREEAM. Amaphaneli amaningi e-PIR aphezulu manje anesimpilo seminyaka engama-25 kuya kwengama-30 ngaphandle kokuwohloka okukhulu.
Ukukhetha phakathi kwe-PU, i-PIR, kanye noboya bedwala kudinga ukulinganisela izidingo zokushisa ngokumelene nezingozi zomlilo. Amaphaneli e-PIR okwamanje anikeza ikhambi eliguquguqukayo kakhulu lokugcina amakhaza esimanje ngenxa yezinga lawo eliphezulu le-R kanye nezakhiwo ezivimbela umlilo. Uboya bedwala buhlala buyindlela ejwayelekile yezindawo ezinobungozi obukhulu lapho ukuphepha komlilo kuyinto eza kuqala khona. I-PU iyindlela esebenzayo yezinhlelo zokusebenza ezincane, ezinobungozi obuphansi ezinesabelomali esincane.
