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.
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 kwenqwaba kanye nokusetshenziswa kwamandla kwe-compressor yizizathu eziqondile zokuphansi. I-COP. 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.
