Uyini umehluko phakathi kwe-R404a kanye ne-R507 refrigerant?

I-refrigerant R410A iyinhlanganisela ye-HFC-32 kanye ne-HFC-125 (isilinganiso sobuningi esingu-50%/50%). I-refrigerant ye-R507 iyi-refrigerant exubile ye-azeotropic engeyona i-chlorine. Iyigesi engenambala ekushiseni kwegumbi kanye nengcindezi. Iyigesi encishisiwe egcinwe kusilinda sensimbi.

Tumehluko phakathi kwe-R404a ne-R507

1. I-R507 kanye ne-R404a zingathatha indawo yesiqandisi esingangcolisi imvelo esingu-R502, kodwa i-R507 ngokuvamile ingafinyelela izinga lokushisa eliphansi kune-R404a, elifanele imishini emisha yokuqandisa yezentengiselwano (iziqandisi eziqandisiwe ezitolo ezinkulu, indawo yokugcina ebandayo, amakhabethe okubonisa, ezokuthutha), imishini yokwenza iqhwa, imishini yokuqandisa ezokuthutha, imishini yokuqandisa yasolwandle noma imishini ebuyekeziwe ifanele zonke izindawo lapho i-R502 ingasebenza khona ngokujwayelekile.
2. Idatha ekulinganisweni kokucindezela kanye nokushisa kwe-R404a kanye ne-R507 ikhombisa ukuthi ingcindezi phakathi kwalokhu okubili icishe ifane. Uma uvame ukunaka izesekeli zesistimu ezisetshenziswayo, uzothola ukuthi incazelo yelebula ku-valve yokwandisa ukushisa yabelwe yi-R404a kanye ne-R507.
3. I-R404A iyingxube engeyona eye-azeotropic, futhi igcwaliswa ngesimo soketshezi, kuyilapho i-R507 iyingxube ye-azeotropic. Ukuba khona kwe-R134a ku-R404a kwandisa ukumelana nokudluliselwa kwesisindo futhi kunciphisa i-coefficient yokushisa yegumbi lokudlulisa, kuyilapho i-coefficient yokudluliselwa kokushisa ye-R507 iphakeme kuneye-R404a.
4. Uma sibheka imiphumela yokusetshenziswa komkhiqizi wamanje, umphumela we-R507 ushesha ngempela kunowe-R404a. Ngaphezu kwalokho, ukusebenza kwe-R404a kanye ne-R507 kusondelene kakhulu. Ukusetshenziswa kwamandla e-compressor kwe-R404a kuphakeme ngo-2.86% kunowe-R507, izinga lokushisa lokukhipha le-compressor enomfutho ophansi liphakeme ngo-0.58% kunowe-R507, kanti izinga lokushisa lokukhipha le-compressor enomfutho ophakeme liphakeme ngo-2.65% kunowe-R507. I-R507 iphakeme ngo-0.01, kanti izinga lokushisa eliphakathi liphansi ngo-6.14% kunowe-R507.
5. I-R507 iyi-refrigerant ye-azeotropic enezinga lokushisa eliphansi lokushelela kune-R404a. Ngemva kokuvuza nokushaja izikhathi eziningana, ushintsho lokwakheka kwe-R507 luncane kune-R404a, umthamo wokupholisa we-volumetric we-R507 awushintshi ngokuyisisekelo, futhi umthamo wokupholisa we-volumetric we-R404a wehliswa cishe ngo-1.6%.
6. Ukusebenzisa i-compressor efanayo, amandla okupholisa e-R507 makhulu ngo-7%-13% kuneka-R22, kanti amandla okupholisa e-R404A makhulu ngo-4%-10% kuneka-R22.
7. Ukusebenza kokudlulisa ukushisa kwe-R507 kungcono kunokwe-R404a kungakhathaliseki ukuthi iqukethe uwoyela wokugcoba noma ayinawo uwoyela wokugcoba.
