Amaphaneli egumbi lokubanda le-PU ne-PIR alawula ukwakhiwa kwesitoreji sesimanje sezinto zokubanda. Izinto ngazinye zinikeza izinzuzo ezicacile ekufakweni kokushisa, ukuphepha, kanye nezindleko. Ukuqonda umehluko wazo kusiza abatshalizimali, abaklami, kanye nabaqhubi ukuthi bakhethe ikhambi elifanele kakhulu lokusebenza kwesikhathi eside.
Ayini Amaphaneli Egumbi Elibandayo le-PU?
Amaphaneli egumbi elibandayo le-PU asebenzisa i-polyurethane foam njengento yokuvikela eyinhloko. I-PU foam inesakhiwo samaseli avaliwe esihlinzeka ngokushisa okuphansi kanye nokunamathela okuqinile ebusweni bensimbi. Ngenxa yalezi zakhiwo, amaphaneli e-PU abe yisinqumo esijwayelekile sokugcina ukudla okubandayo, amakamelo abandayo, kanye namakamelo aqandisayo.
Ukushisa Okuhle Kakhulu:Inzuzo enkulu yamaphaneli e-PU ilele ekushiseni kwawo okuhle kakhulu. Ukushisa okuvamile kuphakathi kuka-0.022 no-0.024 W/m·K, okusiza ukugcina amazinga okushisa angaphakathi azinzile futhi kunciphisa ukusetshenziswa kwamandla esiqandisini. Kumaphrojekthi anobukhulu obulinganiselwe bodonga, amaphaneli e-PU avumela abaklami ukuthi bafinyelele imigomo yokushisa ngaphandle kokwandisa ubukhulu besakhiwo.
Amaphaneli e-PU nawo anikeza ukusebenza kahle kwezindleko. Izinto zokusetshenziswa kanye nezinqubo zokukhiqiza zihlala zivuthiwe, okugcina amanani encintisana. Kumaphrojekthi okugcina amakhaza amancane naphakathi nendawo, amaphaneli e-PU avame ukunikeza ibhalansi engcono kakhulu phakathi kokusebenza kanye nokulawulwa kwesabelomali.
Kodwa-ke, amaphaneli e-PU abonisa imikhawulo ekusebenzeni komlilo. I-PU foam ejwayelekile ingeyomkhakha wesilinganiso somlilo we-B2. Ngaphansi kwamazinga okushisa aphezulu, i-PU ingathambisa futhi ikhiphe intuthu. Nakuba izithasiselo ezivimbela ilangabi zithuthukisa ukuphepha, amaphaneli e-PU asabhekene nezinselele zokuvunywa ezinzima kumaphrojekthi anezidingo eziphezulu zokuvikela umlilo.
Ayini Amaphaneli Egumbi Elibandayo le-PIR?
Amaphaneli egumbi elibandayo le-PIR asebenzisa i-polyisocyanurate foam njengento eyinhloko. I-PIR foam yakha ngokusebenzisa ukusabela kwamakhemikhali okushintshiwe okudala isakhiwo sendandatho esizinzile. Lesi sakhiwo sithuthukisa kakhulu ukumelana nomlilo kanye nokuqina kokushisa.
Ukusebenza Komlilo Okuphezulu:Inzuzo ebaluleke kakhulu yamaphaneli e-PIR ukusebenza kahle komlilo. Ukufakwa kwe-PIR kuvame ukufinyelela izinga lomlilo le-B1 futhi kubonisa ukumelana okungcono nokusabalala komlilo kanye nokukhiqizwa kwentuthu. Esimweni somlilo, i-PIR yakha ungqimba lwe-char oluvikelayo olunciphisa ukudluliselwa kokushisa kanye nomonakalo wesakhiwo. Kumaphrojekthi okugcina abandayo emapaki okuthutha, ezindaweni zemithi, noma ezindaweni zasemadolobheni, lesi sici sinikeza inzuzo enkulu yokuphepha.
Amaphaneli e-PIR nawo asebenza kahle ekushiseni okushisa. Ukushisa kwawo kuvame ukuba phakathi kuka-0.021 no-0.023 W/m·K, okulingana noma okuthuthuka kancane kumaphaneli e-PU. Ngemijikelezo yokusebenza emide, lo mehluko ungaholela ekongeni amandla okulinganisa, ikakhulukazi emakamelweni efriji anezinga lokushisa eliphansi.
Inkinga enkulu yamaphaneli e-PIR ihilela izindleko. Ukukhiqizwa kudinga izinto zokusetshenziswa zezinga eliphezulu kanye nokulawulwa kwenqubo okuqinile, okwandisa amanani amaphaneli cishe ngo-10% kuya ku-20% uma kuqhathaniswa namaphaneli e-PU. Ngaphezu kwalokho, i-PIR foam ikhombisa ukuphuka okuphezulu kancane, ngakho-ke ukuphathwa ngokucophelela ngesikhathi sokufakwa kuba kubalulekile.
Ukuqhathanisa Amaphaneli e-PIR kanye ne-PU kuzinhlelo zokusebenza ze-Cold Storage
Uma kuqhathaniswa amaphaneli egumbi lokubanda le-PIR ne-PU, ukusebenza kokuvikela kuphela akuchazi ukukhetha kokugcina. Ukuphepha komlilo, isikali sephrojekthi, izinga lokushisa lokusebenza, kanye nezidingo zomthetho konke kudlala indima ebalulekile.
Ukuze kugcinwe ukudla okubandayo okujwayelekile, izindawo zokugcina izimpahla ezintsha, kanye nesitoreji esiqandisiwe sesikhathi esifushane, amaphaneli e-PU avame ukuhlangabezana nezidingo zobuchwepheshe ngezindleko eziphansi. Lawa maphrojekthi avame ukusebenza ezindaweni zezimboni ezilawulwayo, lapho imithetho yomlilo ihlala ilawuleka khona futhi ukusebenza kahle kwezindleko kubaluleke kakhulu.
Kumakamelo okubanda emithi, izikhungo ezinkulu zokuthutha izinto ezibandayo, kanye nezindawo eziqondiswe ekuthumeleni kwamanye amazwe, amaphaneli e-PIR anikeza izinzuzo eziqinile zokuthobela imithetho. Izindinganiso eziningi zomhlaba wonke kanye nabahlinzeki bomshuwalense bathanda izinto ezinokumelana nomlilo okuphezulu, okunciphisa ingozi yokusebenza yesikhathi eside.
Izinga lokushisa lokusebenza liphinde lithinte ukukhetha. Emakamelweni efriji anezinga lokushisa eliphansi kakhulu ngaphansi kuka-30°C, amaphaneli e-PIR agcina ukuzinza kwesakhiwo kangcono ngesikhathi senkonzo ende. Amaphaneli e-PU asasebenza kahle kodwa angase abhekane nokuguga kancane kancane kokushisa ngaphansi kwezimo ezimbi kakhulu.
Indlela Yokukhetha Phakathi Kwamaphaneli Egumbi Elibandayo le-PIR ne-PU
Ukukhetha phakathi kwamaphaneli e-PIR ne-PU kudinga ukuhlolwa okucacile kwezinto eziza kuqala kumaphrojekthi. Uma ukuzwela kwesabelomali kanye nokubuyiselwa okusheshayo kokutshalwa kwezimali kuholela ekwenzeni izinqumo, amaphaneli e-PU ahlinzeka ngokusebenza okuthembekile nokuqinisekisiwe. Afanele amaphrojekthi amancane kuya kwaphakathi nendawo okugcina izinto ezibandayo anezidingo zokuphepha komlilo eziphakathi nendawo.
Uma ukuphepha komlilo, ukuvunyelwa komthetho, kanye nokulawulwa kwengozi yesikhathi eside kuphezulu, amaphaneli e-PIR aba inketho ekhethwayo. Izindleko zawo zokuqala eziphakeme zivame ukuqeda izinzuzo zokuthobela imithetho yesikhathi esizayo, umshwalense, kanye nokuphepha.
Abanikazi bephrojekthi kufanele futhi bacabangele amakhodi okwakha endawo, izidingo zomshuwalense, kanye nesikhathi sokusebenza. Ukubonisana nabakhiqizi bamaphaneli kanye nabaklami bezindawo zokugcina izinto ezibandayo kuqinisekisa ukuthi ukukhethwa kwezinto kuhambisana nomklamo wesakhiwo, umthamo wesiqandisi, kanye nesu lokuphepha.
Amaphaneli egumbi lokubanda le-PIR ne-PU ngalinye linikeza inani eliqinile uma lisetshenziswa ngaphansi kwezimo ezifanele. Ngokulinganisela ukusebenza kokushisa, ukuphepha komlilo, izindleko, kanye nezidingo zomthetho, abathuthukisi bangakhetha uhlelo lwephaneli olusekela imisebenzi yokugcina izinto ezibandayo esebenza kahle, ephephile, futhi ehlala isikhathi eside.
