Uyini umehluko phakathi kwe-R404a ne-R507 yesiqandisi?

Isiqandisi i-R410A siyingxube ye-HFC-32 ne-HFC-125 (50%/50% mass ratio). I-refrigerant ye-R507 iyisiqandisi esixutshwe ne-azeotropic engeyona i-chlorine. Kuyigesi engenambala ekamelweni lokushisa nokucindezela. Kuyigesi eliwuketshezi elicindezelwe eligcinwe kusilinda sensimbi.

Tumehluko phakathi kuka-R404a no-R507

1. I-R507 kanye ne-R404a ingathatha indawo yesiqandisi esingavumelani nemvelo esingu-R502, kodwa u-R507 ngokuvamile ungafinyelela izinga lokushisa eliphansi kune-R404a, elilungele imishini emisha yesiqandisi yezohwebo (iziqandisi zasesuphamakethe, indawo ebandayo, amakhabethe ombukiso, izinto zokuhamba), izinto zokwakha u-Ice, izinto zokuhamba eziqandisiwe lapho kufaneleka khona iziqandisi zasolwandle, zonke izinsimbi zasolwandle. ngokujwayelekile.
2. Imininingwane yamageji okucindezela kanye nezinga lokushisa angu-R404a no-R507 ikhombisa ukuthi ingcindezi phakathi kwalokhu kokubili icishe ifane. Uma ujwayele ukunaka izesekeli zesistimu ezisetshenziswayo, uzothola ukuthi incazelo yelebula kuvalvu yokunweba eshisayo yabelwa ngo-R404a kanye no-R507.
3. I-R404A iyingxube engeyona i-azeotropic, futhi igcwaliswa esimweni esiwuketshezi, kuyilapho i-R507 iyingxube ye-azeotropic. Ukuba khona kwe-R134a ku-R404a kwandisa ukumelana nokudluliswa kwenqwaba futhi kunciphisa i-coefficient yokushisa yegumbi lokudlulisa, kuyilapho i-coefficient yokudlulisa ukushisa engu-R507 iphakeme kunaleyo ye-R404a.
4. Uma sibheka emiphumeleni yokusetshenziswa komkhiqizi wamanje, umphumela we-R507 ngempela uyashesha kunalowo wama-R404a. Ngaphezu kwalokho, ukusebenza kuka-R404a no-R507 kusondele kakhulu. Amandla e-compressor asetshenziswa ngu-R404a aphakeme ngo-2.86% kunalawo angama-R507, izinga lokushisa lokukhipha i-compressor low-pressure liphakeme ngo-0.58% kunalelo lika-R507, kanti izinga lokushisa lokuphuma kwe-high-pressure liphakeme ngo-2.65% kunalelo lika-R507. U-R507 uphakeme ngo-0.01, kanti izinga lokushisa eliphakathi nendawo lingaphansi ngo-6.14% kuno-R507.
5. I-R507 iyifriji ye-azeotropic enezinga lokushisa eliphansi lokushelela kuno-R404a. Ngemva kokuvuza nokushaja izikhathi ezimbalwa, ukuguqulwa kokwakheka kuka-R507 kuncane kunalokhu kuka-R404a, umthamo wokupholisa wevolumu engu-R507 empeleni awushintshile, futhi umthamo wokupholisa wevolumu we-R404a wehliswa cishe ngo-1.6%.
6. Ngokusebenzisa i-compressor efanayo, amandla okupholisa angu-R507 makhulu ngo-7% -13% kunalawo angama-R22, kanti amandla okupholisa angu-R404A angu-4% -10% amakhulu kunalawo angama-R22.
7. Ukusebenza kokudlulisa ukushisa kuka-R507 kungcono kuno-R404a kungakhathaliseki ukuthi kuqukethe uwoyela wokugcoba noma ngaphandle kwamafutha okugcoba.
