Ukusebenza kahle kwe-carbon dioxide air conditioners efrijini ngokuvamile kuphansi kunokwezinhlelo ezivamile ze-refrigerant ngaphansi kwezimo ezifanayo zokusebenza, futhi kuphansi kakhulu. Ukuthi ukufudumala kungaba ngcono ngempela kuyangabazeka. Ngibonile lesi sitatimende ezindaweni eziningi, kodwa angicabangi ukuthi kufinyelelwe esivumelwaneni, futhi angibonanga ukuqhathanisa okuqinisekisayo ngempela. Angiboni muntu esebenzisa izinhlelo nezingxenye eziseduze ngangokunokwenzeka ukuqhathanisa i-CO2 kanye nesetshenziswa njalo. Kuma-refrigerant, uma uqhathanisa imiphumela yokusebenza kahle yamaqembu ahlukene ocwaningo ngaphandle kokukhathalela ukuthi uhlelo oluthile kanye nokukhethwa kwezingxenye kuyafana ngempela, khona-ke imiphumela yokuqhathanisa ayinalo ithonya elikhulu.
Ukushisa kuseduze nokusebenza kahle kwama-refrigerant avamile kunokupholisa, futhi izimo zokushisa eziphansi zisebenza kangcono kune-refrigerant evamile, noma zinganikeza amazinga okushisa aphezulu kune-refrigerant evamile. Ngicabanga ukuthi lezi zitatimende zithembeke kakhulu.
Izinzuzo ze-carbon dioxide njengoketshezi olusebenzayo lwe-air conditioner/ipompo yokushisa:
1. Ngokucindezela okuphezulu kanye nokuxinana okuphezulu, uhlelo lwe-carbon dioxide lungaba luncane futhi lube lula (lufanele izimoto) ngezidingo ezifanayo zokupholisa kanye namandla okushisa.
2. I-viscosity coefficient ephansi kanye nokulahleka okuncane kokugeleza.
3. Ukusebenza kahle kokudlulisa ukushisa.
4. Ngaphansi kwezimo ezifanayo zokusebenza, isilinganiso sokucindezela se-compressor siphansi, kanti ukusebenza kahle kwe-compressor kuphakeme; lokhu kungabonisa izinzuzo esimweni sokusebenza esiphansi sokushisa kwepompo yokushisa.
5. Izinga lokushisa eliphezulu endaweni yokukhipha i-compressor (lingaba ngaphezu kwama-degrees ayi-100, okuyinto engeyinhle ezimweni eziningi) lingasetshenziswa ukwenza ezinye izinto ezingenakukwazi ukwenziwa ngemijikelezo evamile yesiqandisi. Lokho kungafaka phakathi ukuncibilikisa ngokushesha, kungaba amafasitela emoto noma i-heat exchanger. Izinzuzo zingatholakala nasezinhlelweni lapho kudingeka khona amazinga okushisa aphezulu (ama-water heater).
6. Ngaphansi kwezimo zokushisa eziphansi kakhulu, ingcindezi yokugcwala kohlangothi olunengcindezi ephansi lweziqandisi ezivamile izoba ngaphansi kunengcindezi yomoya, ukuze umoya ungene ohlelweni, kodwa i-carbon dioxide ngeke ingene ngenxa yengcindezi ephezulu; lokhu futhi kuyinzuzo engaba khona ekusetshenzisweni kwepompo yokushisa.
7. Ukusebenzisa i-internal heat exchanger (IHX) kanye ne-ejector (ejector) ukuze kubuyiselwe umsebenzi wokukhulisa, ukusebenza kahle kungathuthukiswa kakhulu. I-IHX ingase ingabizi, kodwa i-ejector ibiza kakhulu.
8. Ukushelela kwezinga lokushisa kohlangothi olunomfutho ophezulu womjikelezo we-carbon dioxide transcritical akuyona into enhle ngokwayo, kodwa ngezinhlelo zokusebenza ezidinga izinguquko ezinkulu zokushisa (njengezifudumezi zamanzi), uma kwenzeka zifana, uma kuqhathaniswa neziqandisi ezivamile, akunakwenzeka ngokwemvelo. Ukulahlekelwa kokusebenza okubangelwa ukushelela kwezinga lokushisa okugwenyiwe kuncane kakhulu, futhi lokhu kusiza ekusetshenzisweni okuthile kungasiza futhi ukusebenza kahle kwamaphampu okushisa e-carbon dioxide ukusondela noma ngisho nokwedlula ukusebenza kahle kwamaphampu okushisa avamile.
