1. Environmental Regulations (GWP theem-down)
Raws li Montreal Protocol Kigali Amendment, lub teb chaws yuav tsum tau theem qis dua -GWP HFCs (xws li R410A).
R410A's GWP ≈ 2088 yog siab dhau rau kev siv sijhawm ntev -.
R32's GWP ≈ 675 yog hais txog ⅓ ntawm R410A, ua raws li cov cai tshiab thoob ntiaj teb (EU F- roj, Tuam Tshoj theem- nqis, thiab lwm yam).
Qhov no ua rau R32 yav tom ntej - pov thawj cov tshuaj piv rau R410A.
2. Cov cuab yeej ua haujlwm zoo sib xws
R32 twb yog 50% ntawm R410A qhov sib tov, yog li nws muaj qhov zoo sib xws, qhov kub thiab txias, thiab kev tsim qauv tsim.
Qhov no txhais tau hais tias cov tuam txhab tuaj yeem hloov kho R410A cov tshuab rau R32 nrog kev hloov me me (valve, qauv kev nyab xeeb, nqi loj).
Engineers nyiam R32 vim nws tsis xav tau kev tsim qauv tshiab.
3. Kev siv hluav taws xob zoo dua
R32 muaj peev xwm ua kom txias dua ib kg thiab zoo dua cov khoom hloov hluav taws xob.
Cov tshuab siv R32 feem ntau ua tiav 5-10% kev ua haujlwm siab dua (COP) dua li R410A systems.
R32 yuav tsum tau 20-30% tsawg dua cov tub yees, txo cov nqi hluav taws xob thiab ib puag ncig hneev taw.
4. Kev lag luam txais yuav
Nyiv (Daikin, Panasonic) thawj zaug tau txais R32 hauv thaj chaw AC nyob ib ncig ntawm 2012-2013.
EU ua raws li F-Cov kev cai roj.
Tam sim no Tuam Tshoj, Is Nrias teb, Middle East, thiab North America tab tom hloov mus rau R32 hauv vaj tse thiab lub teeb lag luam ACs.
Feem ntau cov OEMs loj (Daikin, Midea, Gree, LG, Mitsubishi, Carrier, thiab lwm yam) tau tso tawm R32-based systems.
5. Kev nyab xeeb sib npaug (A2L vs A1)
R32 yog me ntsis flammable (A2L), thaum R410A tsis yog -flammable (A1).
Txawm li cas los xij, cov qauv kev nyab xeeb (IEC 60335-2-40) tso cai rau R32 siv hauv tsev thiab kev lag luam AC nrog kev txwv kom raug, kev kuaj pom, thiab qhov cua tsim.
Txij li thaum R32 qhov flammability qis dua li cov hydrocarbons (xws li R290 / propane), nws tau pom tias muaj kev cuam tshuam zoo ntawm qhov qis -GWP thiab tswj tau qhov kev pheej hmoo ntawm kev nyab xeeb.
Vim li cas R32 yog qhov nyiam hloov pauv

Xaus:
R32 suav hais tias yog qhov hloov pauv ncaj qha rau R410A vim tias nws muaj GWP qis dua, kev ua haujlwm zoo dua, thiab kev sib raug zoo nrog R410A cov qauv tsim, thaum ua kom muaj kev nyab xeeb ntawm kev tswj tau raws li cov qauv thoob ntiaj teb.
