Kune akawanda ezvisarudzo zvefiriji zvinotengeswa pamusika nhasi, kusanganisira akawanda mafiriji masanganiswa, ayo anovavarira kudzokorora mashandiro evaimbove mabhiza senge R22, kugadzirwa kwayo kwakaitwa zvisiri pamutemo muna Ndira wegore rino. Mienzaniso miviri yakakurumbira yemafiriji akagadzirwa mumakore makumi matatu apfuura kana kuti anoshandiswa muindasitiri yeHVAC iR-410A neR-407C. Aya mafiriji maviri anowanzo shandiswa kuita zvakafanana, asi ane mimwe misiyano yakasarudzika inofanirwa kunzwisiswa nekutariswa pakusarudza pakati pawo.
R-407C
Yakagadzirwa nekubatanidza R-32, R-125, uye R-134a, R-407C musanganiswa we zeotropic, zvichireva kuti zvinhu zvayo zvinofashaira patembiricha dzakasiyana. Zvinhu zvinosanganisira R-407C zvinoshandiswa kuwedzera hunhu hunodiwa, neR-32 inopa huwandu hwekupisa, R-125 inopa kudzika kwakadzika, uye R-134a inoderedza kudzvanywa.
Imwe bhenefiti yekushandisa R-407C pakakwirira-ambient mamiriro ndeyekuti inoshanda pane yakaderera. Imwe dhiraivha yekucherechedza, zvakadaro, ndeye R-407C's glide ye10°F. Nekuti R-407C musanganiswa we zeotropic, glide ndiwo musiyano wetembiricha pakati pezvinhu zvitatu zvinofashaira. Kunyange madhigirii gumi angaita seakawanda, anogona kuve nemhedzisiro chaiyo pane zvimwe zvinhu zvehurongwa.
Iyi glide inogona kukanganisa kuita kwesystem mune yakakwira-ambient mamiriro, nekuda kwepedyo tembiricha yepedyo pakati peiyo condensing point yeyekupedzisira condensing refrigerant uye kuyerera kwemhepo. Kuwedzera tembiricha yekumisikidza inogona kunge isiri iyo inoyevedza sarudzo, nekuda kwekubuda kwakanyanya kunobvumidzwa kune compressor. Kutsiva izvi, zvimwe zvinhu zvakaita semakoiri econdenser kana mafeni econdenser anofanirwa kuve akakura, izvo zvinouya nehuwandu hwezvinoreva, zvakanyanya kutenderedza mutengo.
R-410A
Kufanana neR407C, R-410A isanganiswa yeotropic, uye inogadzirwa nekubatanidza R-32 uye R-125. Munyaya yeR-410A, zvisinei, mutsauko uyu pakati pemapoinzi avo maviri ari kufashaira wakanyanya kudiki, uye refrigerant inoonekwa sepedyo-azeotropic. Azeotropes misanganiswa ine inogara ichifashaira poindi, iyo miyero haigone kushandurwa nenzira ye distillation.
R-410A inonyanya kufarirwa kune akati wandei HVAC application, senge macondenser. Nekudaro, patembiricha yakakwira, R-410A's Operation pressure yakanyanya kudarika R-407C, zvichiita kuti vamwe vafunge nezvedzimwe sarudzo dzekushandisa kwakadaro. Nepo R-410A's's operating pressure at high ambient tembiricha yakakwira zvisingaite kupfuura iyo R-407C, paSuper Radiator Coils, tinokwanisa kugadzira mhinduro dzakanyorwa neUL dzinoshandisa R-410A kusvika mazana manomwe PSIG, zvichiita kuti ive yakakwana. yakachengeteka uye inoshanda refrigerant yemamiriro okunze anodziya.
R-410A inonyanya kufarirwa kune yekugara uye yekutengesa mhepo yekumisikidza mumisika yakati wandei, kusanganisira United States, Europe, uye zvikamu zveAsia. Kutya pamusoro pekushanda kwayo kwakanyanya mukudziya kwe tembiricha inogona kutsanangura kuti sei R-410A isiri kuwanda munzvimbo dzakaita seMiddle East kana nzvimbo dzinopisa dzepasi.
