R1234yf ndeimwe yeakanakisa mamwe mafiriji eR134a. Kuti udzidze firiji uye kupisa kuita kweR1234yf system,itsva simba motokari kupisa pombi air conditioningbhenji rekuedza rakavakwa, uye misiyano mufiriji uye kupisa kwekuita pakati peR1234yf system neR134a system yakaenzaniswa kuburikidza nekuyedza. Mhedzisiro yekuedza inoratidza kuti kutonhora kwesimba uye COP yeR1234yf system yakaderera pane iyo yeR134a system. Pasi pemamiriro ekupisa, kugadzirwa kwekupisa kweR1234yf system kwakafanana neyeR134a system, uye COP yakaderera pane R134a system. Iyo R1234yf sisitimu inonyanya kubatsira kune yakagadzikana kushanda nekuda kwekudzika kwayo tembiricha yekupisa.
R134a ine kudziya kwepasi rose (GWP) ye1430, inova iyo yepamusoro-soro GWP pakati pemafiriji anowanzo shandiswa. Nekuwedzera kwekuziva kwevanhu kwezvakatipoteredza, kushandiswa kwepamusoro GWP refrigerants kwakatanga kuderedzwa zvishoma nezvishoma. Iyo firiji nyowani R1234yf, nekuda kweGWP yayo ye4 chete neODP ye0, ine zvinhu zvekupisa zvakafanana neR134a uye inotarisirwa kuve imwe yemafiriji akakodzera eR134a.
Mutsvagiridzo iyi yekuyedza, iyo R1234yf inotsiviwa zvakananga muR134asimba idzva kupisa pombi air conditioning system bhenji rekuedza, uye musiyano wekuita pakati peR1234yf system uye R134a system pasi pefiriji yakasiyana uye mamiriro epombi yekupisa inodzidzwa. Mhedziso dzinotevera dzinoitwa.
1) Pasi pemamiriro efriji, simba rekutonhora uye COP yeR1234yf system yakaderera pane iyo yeR134a system, uye gap reCOP rinowedzera zvishoma nezvishoma nekuwedzera kwekutenderera kwekutenderera. Kuenzaniswa nekutamisa kupisa mucondenser uye kutonhora kwesimba muevaporator, iyo yakakwira yakawanda yekuyerera mwero weR1234yf system inotsiva iyo yakadzika yakadzika kupisa kwemhepo.
2) Pasi pemamiriro ekupisa, kugadzirwa kwekupisa kweR1234yf system kwakaenzana neiyo yeR134a system, uye COP yakaderera pane iyo yeR134a system, uye huwandu hwekuyerera uye kushandiswa kwesimba re compressor ndizvo zvikonzero zvakananga zvepasi. COP. Pasi pemamiriro ekunze ekupisa, nekuda kwekuwedzera kwehuwandu hwekusimudzira uye kudzikira kwekuyerera kwehuwandu, kudzikisira kwekugadzira kupisa kwemasisitimu ese ari maviri kwakakomba.
3) Mumamiriro ekutonhora uye ekudziya, tembiricha yekuburitsa yeR1234yf yakaderera pane iyo yeR134a system, iyo inobatsirakushanda kwakagadzikana kwegadziriro.
