Difluoromethane (R-32) ubedo piny ma rangi pare epe, epe ku tho, man epe ku lyethu manok (HFC) ku tic maber mi lyethu. Calu piny ma nyen ma nyayu lyethu ma ber pi kwo pa lei, edoko piny ma pire tek ma copo loko kwo pa piny ma nyayu lyethu, ma dhanu mapol ungiyu pi bedo maber, bedo ber, man bedo ber pa piny.
Piny ma pire tek
| Piny | Lembe ma pire tek | Bero |

| GWP (Global Warming Potential, 100 - oro) | 675 | Piny ma piny uloyu R - 410A (GWP = 2088) man R - 22 (GWP = 1810), ma dwoko piny rwom pa lyethu |
| ODP (Ozone Depletion Potential) | 0 | Pe nyayu peko ikum ozone layer, ma lubu cik mi ng'om zoo (e.g., Montreal Protocol) |
| Liet ma pire tek | 78.1°C (172.6°F) | Ber pi yamo ma ngic man jam lyethu ma tiyo ikabedu ma ngic mandha |
| Lwiny | Ma nya wang nyanok (A2L classification nimakere ku ASHRAE 34) | Ber pi kabedo mapol man tic mi kuloka ku yub maber |
| Thermal Conductivity | Malu (ber uloyu R - 410A) | Medu kero pa lyethu/lyeyo, dwoko piny tic pa jam tic ku mac |
Tic ma rwinyo
R-32 jutiyo kudu lee i kabedo matung tung mi tic man mi wil pi tic pare maber man bero pa kwo pa piny:
Yamu ma ngic mi ot man mi cato wil: Calu piny ma ngic ma pire tek pi AC ma jupoko, AC mi dirisa, man VRV (Variable Refrigerant Volume) systems. Eloko R-410A i jam tic manyen, ma dwoko piny tic ku mac ku 10-15%.
Pump mi lyethu: Ber pi pampu mi lyethu ma wok kud i yamo (ASHPs) man pampu mi lyethu ma wok kud i pii (WSHPs), ma mio tic mi lyethu maber kadi i kabedo ma piny lyeth (-10°C ku 5°C).
Refrigerator Systems: Jutiyo kudu i friji ma nok man ma dit, kabedo mi nyuthu piny, man kama jugwoku i iye piny ma ngic, ma weko piny bedo maleng man ma rac ungo.
Jam tiyo ku foam: I tic moko mi tic, R-32 timo tic calu jamb tiyo ku polyurethane ma tek, ma medo kero pa foam.
Organic Synthesis: Tiyu calu piny ma jutiyo kudu pi yubu kemikol ma fluorinated, ikinde utiye yath man polymers ma pire tek.

Tiyu kude: Kur mako adila/wang; ti ku gloves mi gwoko kum, goggles, man jam tic mi yuyu i kabedu ma yamo kadhu kud i iye marac.
Ka gwoko: Gwoko kama ngic, ma muthwo, ma yamo wok iye maber mabor ku mac, lyethu ma malo, man piny ma nyayu yamo. Ti ku piny ma cego, ma rwinyo ngo (e.g., silinda mi cuma nyo aluminium).
Woth: Lub cik pa UN pi tero piny ma ngic (namba pa UN: 3252); nen nia cylinders ucungo maber man jugoro nying gi.
Lubu cik
Urombo ku cik pa ASHRAE 34 (A2L safety classification).
Lubu cik pa EU F-Gas Regulation (Cik (EU) 2014/512), ma jwigo F-gas man cwaku yore mukende ma GWP migi nok.
Juyiyu ku ju ma yiku jam tic madongo (calu, Daikin, Mitsubishi Electric, Gree) pi tic kudu i AC man heat pump migi manyen.

Pirango ma wayero Difluoromethane (R-32) mwa?
Lengo ma malo: Leng pa 99.9% ma rom rom miyo jam tic tiyo maber man kwo ma rii.
Eco-Friendly: Low GWP (675) konyo yub mi gwoko kwo pa piny man lubo cik ma tek mi gwoko kwo pa piny.
Bei maber: Tic maber pa lyethu dwoko piny wel pa mac ni jutic, man kero mwa mi kelo piny madwong dwoko piny wel mi wil.
Kony mi ng'om zoo: Wamiyo kony mi tic, ponji mi gwoko kwo, man cwalo piny i sawa ma'atira ni juruwil i ng'om zoo, ku certificate ma uketho i iye ISO 9001 man REACH.
