Dab tsi yog qhov txawv ntawm R404a thiab R507 tub yees?

Lub tub yees R410A yog qhov sib xyaw ntawm HFC-32 thiab HFC-125 (50% / 50% huab hwm coj piv). R507 tub yees yog ib qho uas tsis yog-chlorine azeotropic mixed refrigerant. Nws yog cov roj tsis muaj xim ntawm chav tsev kub thiab siab. Nws yog compressed liquefied gas khaws cia rau hauv lub tog raj kheej steel.

TNws txawv ntawm R404a thiab R507

1. R507 thiab R404a tuaj yeem hloov pauv tus phooj ywg ib puag ncig ntawm R502, tab sis R507 feem ntau tuaj yeem ncav cuag qhov kub qis dua R404a, uas yog tsim rau cov khoom siv tub yees tshiab (lub khw muag khoom tub yees, txias cia, khoom txee, tsheb thauj mus los), Cov khoom siv dej khov, cov khoom siv tub yees tsheb thauj mus los, R404a refrigeration, cov khoom siv hauv tsev thiab cov khoom siv tub yees. ib txwm.
2. Cov ntaub ntawv ntawm lub siab thiab ntsuas kub ntawm R404a thiab R507 qhia tias lub siab ntawm ob qhov yuav luag tib yam. Yog tias koj feem ntau xyuam xim rau cov khoom siv hauv lub cev siv, koj yuav pom tias cov lus piav qhia ntawm cov thermal expansion valve yog sib koom los ntawm R404a thiab R507.
3. R404A yog ib qho tsis-azeotropic sib tov, thiab nws tau ntim rau hauv lub xeev ua kua, thaum R507 yog ib qho azeotropic sib tov. Lub xub ntiag ntawm R134a hauv R404a nce qhov hloov pauv huab cua thiab txo cov cua sov coefficient ntawm cov khoom hloov pauv, thaum lub tshav kub hloov pauv coefficient ntawm R507 yog siab dua li ntawm R404a.
4. Kev txiav txim los ntawm cov chaw tsim khoom siv tam sim no, cov nyhuv ntawm R507 yog qhov tseeb nrawm dua li ntawm R404a. Tsis tas li ntawd, kev ua yeeb yam ntawm R404a thiab R507 yog qhov ze. Lub zog siv hluav taws xob ntawm R404a yog 2.86% siab dua li ntawm R507, qhov tso tawm qhov kub ntawm qhov tsis tshua muaj siab compressor yog 0.58% siab dua li ntawm R507, thiab qhov tso tawm qhov kub ntawm high-pressor compressor yog 2.65% siab dua li ntawm R507. R507 yog 0.01 siab dua, thiab qhov nruab nrab kub yog 6.14% qis dua R507.
5. R507 yog ib qho azeotropic refrigerant nrog qis qis dua kub dua R404a. Tom qab xau thiab them nyiaj ntau zaus, qhov kev hloov pauv ntawm R507 yog me dua li ntawm R404a, lub peev xwm txias ntawm R507 yog qhov pib tsis hloov, thiab lub peev xwm ua kom txias ntawm R404a yog txo los ntawm 1.6%.
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.
7. Lub tshav kub hloov kev ua tau zoo ntawm R507 zoo dua li ntawm R404a tsis hais seb nws muaj cov roj lubricating lossis tsis muaj roj lubricating.
