Ukukhetha iiphaneli zesandwich ezifanelekileyo ezigqunyiweyo sisigqibo esibalulekileyo ekwakheni indawo yokugcina ebandayo. Izinto eziphambili zeephaneli zesandwich zilawula ukusebenza kakuhle kwamandla, ukhuseleko lomlilo, kunye nobude besakhiwo. Abaqhubi kufuneka bakhethe phakathi kwe-PU, i-PIR, kunye noboya belitye ngokusekelwe kwiimfuno ezithile zobushushu kunye nokhuseleko. Uhlobo ngalunye lweephaneli zesandwich ezigqunyiweyo lubonelela ngeenzuzo kunye nemingeni eyahlukeneyo yolawulo lwesakhiwo sexesha elide.
Ukusebenza kobushushu kunye nokonga amandla
Ukuqhuba ubushushu, okanye ixabiso le-R, limisela ukuba iphaneli iyamelana njani nokuhamba kobushushu. Iiphaneli ze-PU kunye ne-PIR zikhokela kwimarike ekusebenzeni kakuhle kobushushu. Iiphaneli zesandwich ezigqunywe yi-PU zihlala zibonelela ngokuqhuba ubushushu obumalunga ne-0.022 W/m·K. Olu buchule buphezulu luvumela iindonga ezincinci ngelixa zigcina imozulu yangaphakathi ezinzileyo. I-PIR yinguquko ye-PU kwaye inika uzinzo olungcono ngakumbi lobushushu.indawo yokugcina ubushushu obukhulu, ukutshintsha ukusuka kwi-insulation eqhelekileyo ukuya kwi-PIR yodidi oluphezulu kunokunciphisa imfuno yamandla okupholisa nge-15% ukuya kwi-20%. Oku kuncitshiswa kuthetha ukuba kugcinwe amawaka eedola ngonyaka kwindawo yokugcina impahla ephakathi.
Iiphaneli zoboya belitye zine-conductivity ephezulu kakhulu yobushushu, zihlala zimalunga ne-0.035 ukuya kwi-0.040 W/m·K. Ukuze ufumane isiphumo esifanayo sokukhusela njengephaneli ye-100mm PIR, kuya kufuneka iphaneli yoboya belitye ephantse ibe yi-180mm ubukhulu. Obu bukhulu bungaphezulu bunciphisa umthamo wokugcina wangaphakathi wesakhiwo sakho. Idatha ibonisa ukuba ukusebenzisa i-PIR ngaphezu koboya belitye kunokunyusa indawo yephalethi esebenzisekayo nge-5% ukuya kwi-8% kwindawo efanayo yesakhiwo. Kumashishini abeka phambili iindleko eziphantsi zombane kunye nobuninzi bokugcina, i-PU kunye ne-PIR zihlala zizezona zikhetho ziphambili. Zinciphisa umthwalo womsebenzi kwiicompressors kwaye zandisa ubomi benkqubo yonke yokufriji.
Ukhuseleko lomlilo kunye neziphumo ze-inshurensi
Ukumelana nomlilo kulapho uboya belitye bugqwesa khona ngaphaya kwamagwebu okwenziwa. Uboya belitye buyinto engatshiyo eneqondo lokunyibilika elingaphezulu kwe-1,000°C. Buhlala bufikelela kwinqanaba lomlilo le-A1, bubonelela ngokhuseleko oluphezulu kwiindawo ezinobungozi obukhulu. Ngokwahlukileyo koko, iiphaneli ze-PIR “azinamlilo.” Ziyatsha xa zibekwe elangatyeni, zenze umaleko okhuselayo ocothisa ukusasazeka komlilo. I-PIR idla ngokuhlangabezana nemigangatho ye-B-s1, d0 phantsi kohlelo lwaseYurophu. NgelixaIiphaneli ze-PUzixhaphakile, azinawo amandla okumelana nomlilo kwaye zinokubangela umsi omninzi ngexesha lomlilo.
Iinkampani zeinshorensi zizithanda kakhulu iiphaneli ze-rock wool kunye ne-FM-envited PIR. Izakhiwo ezisebenzisa iiphaneli ze-PU eziqhelekileyo zihlala zijongene neeprimiyamu zeinshorensi eziphezulu ngama-20% ukuya kuma-30% kunezo zisebenzisa uboya be-rock. Kwezinye iindawo, abanini-inshorensi banokwala ukugubungela iivenkile ezibandayo ezingenazo ii-cores eziqinisekisiweyo zokumelana nomlilo. Isiganeko esinye somlilo kwiziko elifakwe i-PU-insulated sinokukhokelela ekuweni kwesakhiwo ngokupheleleyo kwimizuzu embalwa. Iiphaneli ze-rock wool zibonelela ngesithinteli somlilo esibalulekileyo, zihlala zibonelela ngemizuzu engama-60 ukuya kwe-120 yokuqina komlilo. Olu khuselo lusindisa ubomi kwaye luthintela ukulahleka okupheleleyo kwezinto ezibizayo kunye neempahla zesakhiwo ngexesha likaxakeka.
Ukunyaniseka kwesakhiwo kunye nokumelana nokufuma
Iindawo zokugcina izinto ezibandayo zijongene notshintsho olukhulu kubushushu olubangela uxinzelelo lomzimba kwiiphaneli. Iiphaneli ze-PU kunye ne-PIR zinobulukhuni obuhle kakhulu besakhiwo kunye nomlinganiselo ophezulu wokuqina-ubunzima. Ulwakhiwo lwazo lweeseli ezivaliweyo, oluqhele ukuba ngaphezulu kwama-90%, luthintela umphunga wamanzi ukuba ungene embindini. Ukufuma lutshaba lobushushu; ukonyuka kwe-1% kumxholo womswakama kunokunciphisa ixabiso lobushushu ngama-25%. Ngenxa yokuba i-PIR kunye ne-PU ziyamelana namanzi, zigcina ixabiso lazo le-R kangangamashumi eminyaka. Zikwamelana nemithwalo enzima yee-evaporators ezixhonywe eluphahleni kunye nezixhobo zokupholisa ngokufanelekileyo.
Iiphaneli zoboya belitye zenziwe ngeefayibha zeminerali, ezivulelekileyo ngokwendalo. Ngelixa abavelisi bongeza izinto zokubopha ezithintela amanzi, uboya belitye busenokufunxa umswakama ukuba ulusu lwentsimbi lubhobokile. Uboya belitye obumanzi bulahlekelwa ziimpawu zalo zokukhusela phantse ngokupheleleyo kwaye bube nzima kakhulu. Oku kunyuka kobunzima kunokusongela ukhuseleko lwesakhiwo senkxaso yophahla. Nangona kunjalo, uboya belitye bubonelela ngobushushu obuphezulu be-acoustic, bunciphisa ingxolo yegumbi lezityalo ukuya kuthi ga kwi-30 decibels. Le yinzuzo ebalulekileyo kwizakhiwo ezikufutshane neendawo zokuhlala. Abaqhubi kufuneka baqinisekise ukuvalwa ngokugqibeleleyo kwamalungu oboya belitye ukuthintela "impembelelo yetshimini" yokufuduka komswakama.
Iindleko zoMjikelo woBomi kunye neMpembelelo kwiNdalo
Ixabiso lexesha elide lephaneli liquka ixabiso lokuthenga, ukugcinwa, kunye nokuchithwa ekugqibeleni. Iiphaneli ze-PU zihlala zinexabiso eliphantsi lokuqala, nto leyo eyenza zithandwe kwiiprojekthi ezijongana nohlahlo-lwabiwo mali. Nangona kunjalo, iiphaneli ze-PIR zibonelela ngembuyekezo engcono kutyalo-mali ngenxa yokuxubana kwazo kokusebenza kakuhle kunye namaxabiso aphantsi e-inshorensi. Kwiminyaka eli-15, ukonga amandla okuvela kwi-PIR kudla ngokuhlawula umsantsa wamaxabiso okuqala ngokuphindwe kathathu. Uboya belitye buneendleko eziphezulu zokufakela ngenxa yobunzima balo, budla ngokufuna uzimele wentsimbi oqinileyo kunye nezixhobo zokuphakamisa ezikhethekileyo.
Uzinzo luya luba yinto ephambili ngo-2026. Uboya belitye buphinda busetyenziswe kakhulu kwaye benziwe ngamatye entaba-mlilo amaninzi. Amagwebu e-PU kunye ne-PIR kunzima ukuwasebenzisa kwakhona, nangona iinguqulelo ezintsha ze-"bio-polyol" zingena kwimarike. Xa kubalwa unyawo lwekhabhoni, uboya belitye bufumana amanqaku amahle xa kuchithwa ubomi bonke. Ngokwahlukileyo koko, i-PIR ifumana amanqaku angcono xa kusetyenziswa ikhabhoni kuba igcina amandla amaninzi ngexesha lobomi besakhiwo. Ukukhetha iphaneli enomxholo ophinda usetyenziswe kakhulu kunokunceda indawo ifumane isiqinisekiso se-LEED okanye se-BREEAM. Uninzi lweephaneli ze-PIR eziphambili ngoku zinobomi beminyaka engama-25 ukuya kwengama-30 ngaphandle kokonakala okukhulu.
Ukukhetha phakathi kwe-PU, i-PIR, kunye noboya belitye kufuna ukulinganisela iimfuno zobushushu nxamnye neengozi zomlilo. Iiphaneli ze-PIR okwangoku zibonelela ngesisombululo esiguquguqukayo sokugcina ubushushu banamhlanje ngenxa yexabiso lazo eliphezulu le-R kunye neempawu zazo zokuthintela umlilo. Uboya belitye buhlala bungumgangatho wegolide kwiindawo ezinomngcipheko ophezulu apho ukhuseleko lomlilo luphambili. I-PU lukhetho olusebenzayo kwizicelo ezincinci, ezinomngcipheko omncinci kunye nohlahlo-lwabiwo mali oluncinci.
