Ukusebenza kakuhle kwe-carbon dioxide air conditioners efrijini ngokubanzi kuphantsi kuneenkqubo eziqhelekileyo ze-refrigerant phantsi kweemeko ezifanayo zokusebenza, kwaye kuphantsi kakhulu. Ukuba ukufudumeza kunokuba luncedo ngakumbi kuyathandabuzeka. Ndiyibonile le ngxelo kwiindawo ezininzi, kodwa andicingi ukuba kufikelelwe kwisivumelwano, kwaye andibonanga kuthelekiswa okwanelisayo. Andiboni mntu usebenzisa iinkqubo kunye nezinto ezikufutshane kangangoko ukuthelekisa i-CO2 kunye ne-CO2 esetyenziswa rhoqo. Kwii-refrigerants, ukuba uthelekisa nje iziphumo zokusebenza kakuhle zamaqela ophando ahlukeneyo ngaphandle kokukhathalela ukuba inkqubo ethile kunye nokukhethwa kwezinto ziyafana ngokwenene, ngoko iziphumo zokuthelekisa azinantsingiselo ingako.
Ukufudumeza kusondele kakhulu ekusebenzeni kakuhle kweefriji eziqhelekileyo kunokuphola, kwaye iimeko zobushushu obuphantsi zisebenza ngcono kuneefriji eziqhelekileyo, okanye zinokubonelela ngamaqondo obushushu aphezulu kuneefriji eziqhelekileyo. Ndicinga ukuba ezi ngxelo zithembekile ngakumbi.
Iingenelo zekhabhoni diokside njengolwelo olusebenzayo lwe-air conditioner/ipompo yobushushu:
1. Xa kuxinezelekile kakhulu kwaye kuxinene kakhulu, inkqubo yekhabhoni dayokhsayidi inokuba ncinci kwaye ibe lula ngakumbi (ifanele izithuthi) ngeemfuno ezifanayo zomthamo wokupholisa nowokufudumeza.
2. I-viscosity coefficient ephantsi kunye nokulahleka okuncinci kokuhamba kwamanzi.
3. Ukusebenza kakuhle kokudlulisa ubushushu.
4. Phantsi kweemeko ezifanayo zokusebenza, umlinganiselo woxinzelelo lwecompressor uphantsi, kwaye ukusebenza kakuhle kwecompressor kuphezulu; oku kunokubonisa iingenelo kwimeko yokusebenza yobushushu obuphantsi bepompo yobushushu.
5. Ubushushu obuphezulu kwindawo yokukhupha i-compressor (bunokuba ngaphezulu kwe-100 degrees, into engeyonto ilungileyo kwiimeko ezininzi) bungasetyenziswa ukwenza ezinye izinto ezingenakukwazi ukwenziwa ngemijikelo yesiqhelo ye-refrigerant. Oko kungabandakanya ukunyibilikisa ngokukhawuleza, nokuba ziifestile zemoto okanye i-heat exchanger. Iingenelo zinokufumaneka nakwiinkqubo apho kufuneka khona ubushushu obuphezulu (izifudumezi zamanzi).
6. Phantsi kweemeko zobushushu eziphantsi kakhulu, uxinzelelo lokugcwala kwecala eliphantsi loxinzelelo lweziqandisi eziqhelekileyo luya kuba ngaphantsi koxinzelelo lomoya, ukuze umoya ungene kwinkqubo, kodwa ikharbon diokside ayingeni ngenxa yoxinzelelo oluphezulu; oku kukwaluncedo ekusetyenzisweni kwepompo yobushushu.
7. Ukusebenzisa i-internal heat exchanger (IHX) kunye ne-ejector (ejector) ukubuyisela umsebenzi wokwandisa, ukusebenza kakuhle kunokuphuculwa ngakumbi. I-IHX isenokungabi yindleko, kodwa i-ejector ibiza kakhulu.
8. Ukutyibilika kobushushu becala elinoxinzelelo oluphezulu lomjikelo we-carbon dioxide transcritical akulunganga ngokwako, kodwa kwizicelo ezifuna utshintsho olukhulu lobushushu (ezifana nezifudumezi zamanzi), ukuba ziyahambelana, xa kuthelekiswa neefriji zesiqhelo, akunakwenzeka ngokwemvelo. Ukulahleka kokusebenza okubangelwa kukutyibilika kobushushu okuthintelweyo kuncinci kakhulu, kwaye oku kunceda kwizicelo ezithile kunokunceda ukusebenza kakuhle kweepompo zobushushu zekhabhoni diokside ukusondela okanye ukudlula oko kweefriji zesiqhelo.
