Cov roj refrigerant R410A yog sib xyaw ntawm HFC-32 thiab HFC-125 (50%/50% qhov hnyav piv). R507 refrigerant yog cov roj refrigerant uas tsis muaj chlorine azeotropic sib xyaw. Nws yog cov roj tsis muaj xim ntawm chav tsev kub thiab siab. Nws yog cov roj liquefied uas raug nias cia rau hauv lub tog raj kheej hlau.
TQhov txawv ntawm R404a thiab R507
- R507 thiab R404a tuaj yeem hloov cov tub yees uas tsis ua rau ib puag ncig puas tsuaj ntawm R502, tab sis R507 feem ntau tuaj yeem ncav cuag qhov kub qis dua R404a, uas yog qhov tsim nyog rau cov khoom siv tub yees lag luam tshiab (lub tub yees hauv khw loj, chaw cia khoom txias, txee tso saib, kev thauj mus los), cov khoom siv ua dej khov, cov khoom siv tub yees thauj mus los, cov khoom siv tub yees hauv hiav txwv lossis cov khoom siv hloov kho tshiab yog qhov tsim nyog rau txhua qhov chaw uas R502 tuaj yeem ua haujlwm ib txwm.
- Cov ntaub ntawv ntawm lub ntsuas siab thiab kub ntawm R404a thiab R507 qhia tau tias lub siab ntawm ob qho no yuav luag zoo ib yam. Yog tias koj feem ntau ua tib zoo saib xyuas cov khoom siv hauv lub kaw lus siv, koj yuav pom tias daim ntawv piav qhia ntawm lub qhov cua sov nthuav dav tau sib koom los ntawm R404a thiab R507.
- R404A yog cov khoom sib xyaw uas tsis yog azeotropic, thiab nws tau sau rau hauv lub xeev kua, thaum R507 yog cov khoom sib xyaw azeotropic. Qhov muaj R134a hauv R404a ua rau muaj kev tiv thaiv kev hloov pauv loj thiab txo cov coefficient cua sov ntawm lub chamber hloov pauv, thaum cov coefficient cua sov ntawm R507 siab dua li ntawm R404a.
- Los ntawm kev siv cov txiaj ntsig ntawm cov chaw tsim khoom tam sim no, qhov cuam tshuam ntawm R507 yeej sai dua li R404a. Tsis tas li ntawd, kev ua tau zoo ntawm R404a thiab R507 kuj zoo sib xws. Kev siv zog ntawm compressor ntawm R404a yog 2.86% siab dua li R507, qhov kub tawm ntawm lub compressor qis yog 0.58% siab dua li R507, thiab qhov kub tawm ntawm lub compressor siab yog 2.65% siab dua li R507. R507 yog 0.01 siab dua, thiab qhov kub nruab nrab yog 6.14% qis dua li R507.
- R507 yog ib qho azeotropic refrigerant nrog qhov kub qis dua R404a. Tom qab xau thiab them ntau zaus, qhov kev hloov pauv ntawm R507 me dua li R404a, lub peev xwm txias ntawm R507 yeej tsis hloov pauv, thiab lub peev xwm txias ntawm R404a txo qis li 1.6%.
- Siv tib lub compressor, lub peev xwm txias ntawm R507 yog 7% -13% loj dua li ntawm R22, thiab lub peev xwm txias ntawm R404A yog 4% -10% loj dua li ntawm R22.
- Qhov kev ua haujlwm hloov pauv cua sov ntawm R507 zoo dua li ntawm R404a tsis hais seb nws puas muaj roj lubricating lossis tsis muaj roj lubricating.
