Nying ma ki ngeyo: R-32 (ma calo gin ma kweyo piny)
Difluoromethane (R-32) tye gin ma pe ki kala, pe ki kwiri, ki ma lyel manok ma tye ki tic maber i kom lyeto. Ma calo gin ma ki lwongo ni refrigerant ma pe balo kwo pa dano, en dong odoko gin ma pire tek ma ki tiyo kwede i kom refrigerants ma ki lwongo ni high-GWP (Global Warming Potential), ma ki ngeyo pi tic maber, ber, ki gwoko kwo pa dano.
Jami ma pire tek

Tic ma rwate
R-32 ki tiyo kwede mapol i dul ma pat pat me yubu jami ki luwil pi tic ne maber ki ber pa kwo pa dano:
Gin ma kweyo yamo i ot ki i gang cato wil: Ma calo gin ma kweyo yamo ma pire tek pi jami ma ki lwongo ni split-type AC units, ACs ma tye i wang ot, ki VRV (Variable Refrigerant Volume) systems. En loko R-410A i jami tic manyen, ma dwoko piny tic ki teko ki 10-15%.
Gin ma ki lwongo ni Heat Pumps: Ber pi air-source heat pumps (ASHPs) ki water-source heat pumps (WSHPs), ma miyo tic me lyeto maber kede i rwom me lyeto ma piny (-10°C onyo 5°C).
Jami ma ki tiyo kwede me gwoko ngiico: Ki tiiyo kwede i friji ma tiino onyo ma dit, kama ki nyutu iye jami, ki kama ki gwoko iye ngiico, ma miyo ngiico bedo maber ki balo kwo pa dano.
Gin ma kwanyo yamo: I yub mogo, R-32 tiyo calo gin ma yubu yamo pi polyurethane ma tek, ma weko yamo bedo maber.
Kit ma ki yubu kwede jami ma kwo: tiyo calo gin ma ki tiyo kwede me yubu jami ma ki lwongo ni fluorinated chemicals, medo ki jami ma ki tiyo kwede me cango two ki polymers ma pat pat.

Cik me gwoko kwo
Kit me tic kwede: Kur mako del kom/wang; tic ki glove me gwoke, kiyo wang, ki jami me yweyo i kabedo ma yamo pe donyo iye maber.
Ka gwoko: Gwok kama ngiic, ma otwo, ma yamo donyo iye maber mabor ki mac ma lyel, lyeto ma malo, ki jami ma balo yamo. Tii ki jami ma ki umu, ma pe romo buru (me labolle, jami ma ki yubu ki nyonyo onyo aluminum).
Tero: Lub cik pa UN pi tero jami ma ngiic (namba pa UN: 3252); nen ni cylinder ni ki gwoko maber ki ki coyo nying gi iye.
Lubu cik
rwate ki cik me ASHRAE 34 (A2L safety classification).
Lubu cik me EU F-Gas Regulation (Cik (EU) 2014/512), ma gengo F-gas ma ki cwalo ki kelo yoo mukene ma GWP ne nok.
Ki yee ki bot luyub jami tic madongo (me labolle, Daikin, Mitsubishi Electric, Gree) me tic kwede i AC ki heat pump gi manyen.

Lengo ma malo: Lengo ma rwate ki 99.9% miyo jami tic maber ki kwo pi kare malac.
Pe balo kwo pa dano: GWP ma lapiny (675) miiyo kony bot yub me gwoko kwo pa dano ki rwate ki cik ma kwako gwoko kwo pa dano.
Wel cente ma mite: Tic ki lyeto ma malo dwoko wel cente ma mite pi lutic kwede, kun kero me miyo jami mapol dwoko wel cente ma mite me wilo piny.
Kony me wilobo weny: wa miiyo tam ma mako jami ma mako tic, pwony me gwoko kwo, ki cwalo jami i kare ma opore bot luwil i wilobo weny, ki waraga ma kwako ISO 9001 ki REACH.
