I-R1234yf yenye yeefriji ezizezinye ezifanelekileyo nge-R134a. Ukuze ufunde ukusebenza kwefriji kunye nokufudumeza kwe-R1234yf inkqubo,isithuthi samandla esitsha sempompo yokufudumala umoya womoyaIbhentshi yovavanyo yakhiwa, kwaye umahluko ekusebenzeni kwefriji kunye nokusebenza kokufudumeza phakathi kwenkqubo ye-R1234yf kunye nenkqubo ye-R134a yathelekiswa ngemifuniselo. Iziphumo zovavanyo zibonisa ukuba umthamo wokupholisa kunye ne-COP ye-R1234yf inkqubo ingaphantsi kune-R134a inkqubo. Ngaphantsi kwemeko yokufudumala, ukuveliswa kobushushu benkqubo ye-R1234yf kufana nenkqubo ye-R134a, kwaye i-COP iphantsi kwe-R134a inkqubo. Inkqubo ye-R1234yf inceda ngakumbi ekusebenzeni okuzinzileyo ngenxa yobushushu obuphantsi bokukhupha.
I-R134a inamandla okufudumala kwehlabathi (GWP) ka-1430, eyeyona GWP iphezulu phakathi kwezikhenkcezisi ezisetyenziswa ngoku. Ngokunyuka kolwazi lwabantu ngokusingqongileyo, ukusetyenziswa kweefriji ze-GWP eziphezulu zaqala ukunqunyulwa ngokuthe ngcembe. Ifriji entsha eyi-R1234yf, ngenxa ye-GWP yayo yesi-4 kuphela kunye ne-ODP ye-0, ineempawu ezibonakalayo zobushushu ezifana ne-R134a kwaye kulindeleke ukuba ibe yenye yeefriji ezizezinye ezifanelekileyo nge-R134a.
Kolu phando lovavanyo, i-R1234yf ithathelwa indawo ngokuthe ngqo kwi-R134ainkqubo entsha yokufudumala impompo yobushushu bomoya ibhentshi yokuvavanya, kunye nokwahlukana kwentsebenzo phakathi kwenkqubo ye-R1234yf kunye nenkqubo ye-R134a phantsi kweefriji ezahlukeneyo kunye neemeko zempompo zokushisa zifundwa. Kwenziwa ezi zigqibo zilandelayo.
I-1) Ngaphantsi kweemeko zefriji, amandla okupholisa kunye ne-COP ye-R1234yf inkqubo iphantsi kunenkqubo ye-R134a, kwaye i-gap ye-COP ikhula ngokuthe ngcembe ngokunyuka kwesantya sokujikeleza. Xa kuthelekiswa nokuhanjiswa kobushushu kwicondenser kunye namandla okupholisa kwi-evaporator, isantya esiphezulu sokuhamba kobunzima benkqubo ye-R1234yf ihlawulela ubushushu bayo obusezantsi obufihlakeleyo bomphunga.
2) Ngaphantsi kweemeko zokufudumeza, ukuveliswa kobushushu benkqubo ye-R1234yf ilingana nenkqubo ye-R134a, kwaye i-COP iphantsi kunenkqubo ye-R134a, kunye nesantya sokuhamba kobuninzi kunye nokusetyenziswa kwamandla e-compressor zizizathu ezithe ngqo eziphantsi. I-COP. Phantsi kweemeko zobushushu obuphantsi, ngenxa yokonyuka komthamo othile okhuthazayo kunye nokuncipha kokuhamba kobuninzi, ukuthomalalisa imveliso yobushushu kuzo zombini ezi nkqubo kubi kakhulu.
3) Phantsi kweemeko zokupholisa kunye nokufudumeza, iqondo lobushushu le-R1234yf lingaphantsi kwelo le-R134a yenkqubo, evumela ukubaukusebenza okuzinzileyo kwenkqubo.
