I-R1234yf ingesinye seziqandisi ezikahle zama-R134a. Ukuze ufunde ukusebenza kwesiqandisi nokushisa kohlelo lwe-R1234yf,iphampu yokushisa imoto yamandla entshakwakhiwa ibhentshi lokuhlola, futhi umehluko ekusebenzeni kwesiqandisi nokushisisa phakathi kwesistimu ye-R1234yf kanye nesistimu ye-R134a yaqhathaniswa ngokuhlolwa. Imiphumela yokuhlola ibonisa ukuthi umthamo wokupholisa kanye ne-COP yesistimu ye-R1234yf iphansi kunaleyo yohlelo lwe-R134a. Ngaphansi kwesimo sokushisa, ukukhiqizwa kokushisa kwesistimu ye-R1234yf kufana nesistimu ye-R134a, futhi i-COP iphansi kunesistimu ye-R134a. Uhlelo lwe-R1234yf lusiza kakhulu ekusebenzeni okuzinzile ngenxa yezinga lokushisa eliphansi lokukhipha umoya.
I-R134a inamandla okufudumala komhlaba (GWP) angu-1430, okuyi-GWP ephakeme kakhulu phakathi kweziqandisi ezisetshenziswa kakhulu njengamanje. Ngokukhula kokuqwashisa kwabantu ngemvelo, ukusetshenziswa kweziqandisi ze-GWP eziphezulu kwaqala ukuncishiswa kancane kancane. Isiqandisi esisha esingu-R1234yf, ngenxa ye-GWP yayo engu-4 kuphela kanye ne-ODP ka-0, sinezakhiwo ezibonakalayo ezishisayo ezifana ne-R134a futhi kulindeleke ukuba sibe esinye seziqandisi ezifanelekile ngo-R134a.
Kulolu cwaningo lokuhlola, i-R1234yf ithathelwa indawo ngokuqondile ku-R134auhlelo olusha lwephampu lokushisa lokushisa umoya ibhentshi lokuhlola, kanye nomehluko wokusebenza phakathi kwesistimu ye-R1234yf nohlelo lwe-R134a ngaphansi kwesiqandisi nezimo zephampu yokushisa ezihlukene ziyafundwa. Kufinyelelwa iziphetho ezilandelayo.
1) Ngaphansi kwezimo zesiqandisi, umthamo wokupholisa kanye ne-COP yesistimu ye-R1234yf iphansi kunaleyo yesistimu ye-R134a, futhi igebe le-COP liyakhula kancane kancane ngokunyuka kwesivinini sokujikeleza. Uma kuqhathaniswa nokudluliswa kokushisa ku-condenser namandla okupholisa ku-evaporator, izinga eliphezulu lokugeleza kwesisindo sohlelo lwe-R1234yf lunxephezela ukushisa kwalo okucashile okuphansi kokuhwamuka.
I-2) Ngaphansi kwezimo zokushisa, ukukhiqizwa kokushisa kwesistimu ye-R1234yf kulingana naleyo yesistimu ye-R134a, futhi i-COP iphansi kunaleyo yesistimu ye-R134a, futhi izinga lokugeleza okukhulu kanye nokusetshenziswa kwamandla we-compressor yizizathu eziqondile ze-COP ephansi. Ngaphansi kwezimo zokushisa eziphansi, ngenxa yokwenyuka kwevolumu ethize ekhuthazayo kanye nokuncipha kokugeleza okukhulu, ukuncishiswa kokukhiqizwa kokushisa kwazo zombili izinhlelo kubi kakhulu.
3) Ngaphansi kwezimo zokupholisa nokushisisa, izinga lokushisa le-exhaust elingu-R1234yf liphansi kunalelo lesistimu ye-R134a, evumela ukuthiukusebenza okuzinzile kwesistimu.
