I-Difluoromethane (R-32) iyi-hydrofluorocarbon (HFC) engenambala, engenabuthi, futhi evutha kancane enekhono lokushisa elihle kakhulu. Njenge-refrigerant yesizukulwane esilandelayo enobungani nemvelo, isibe yindlela eyinhloko yokufaka esikhundleni se-refrigerant yendabuko ye-high-GWP (Global Warming Potential), eyaziwa kabanzi ngokulinganisela kwayo ukusebenza kahle, ukuphepha, kanye nobungani bemvelo.
Izakhiwo Eziyinhloko
| Impahla | Imininingwane | Inzuzo |
| Indawo Yokubilisa (ku-1 atm) | -51.6°C (-60.9°F) | Ivumela ukudluliselwa kokushisa okuphumelelayo ezinhlelweni zokusebenza zokushisa okuphansi |
| I-GWP (Amandla Okufudumala Komhlaba Wonke, iminyaka eyi-100) | 675 | Kuphansi kakhulu kune-R - 410A (GWP = 2088) kanye ne-R - 22 (GWP = 1810), okunciphisa ukunyathela kwekhabhoni |
| I-ODP (Ithuba Lokuncishiswa Kwe-Ozone) | 0 | Akukho monakalo owenzekile ongqimbeni lwe-ozone, okuhambisana nemithethonqubo yezemvelo yamazwe ngamazwe (isb., i-Montreal Protocol) |
| Izinga Lokushisa Elibucayi | 78.1°C (172.6°F) | Ifanele izinhlelo zokupholisa umoya kanye nezokupompa ukushisa ezisebenza ezindaweni ezinokushisa okumaphakathi kuya okuphezulu |
| Ukuvutha | Iyasha kancane (ukuhlukaniswa kwe-A2L ngokwe-ASHRAE 34) | Kuphephile kakhulu ezindaweni zokuhlala nezentengiselwano ngomklamo ofanele |
| Ukuqhuba Okushisayo | Kuphezulu (kungcono kune-R - 410A) | Kuthuthukisa ukusebenza kahle kokupholisa/ukushisa, kunciphisa ukusetshenziswa kwamandla kwemishini |
Izicelo Ezijwayelekile
I-R-32 isetshenziswa kabanzi emikhakheni eyahlukene yezimboni kanye neyabathengi ngenxa yokusebenza kwayo okuphezulu kanye nezinzuzo zemvelo:
Umoya Opholile Wendawo Yokuhlala Nokuhweba: Njengesiqandisi esiyinhloko samayunithi e-AC ahlukanisiwe, ama-AC efasiteleni, kanye nezinhlelo ze-VRV (Variable Refrigerant Volume). Ithatha indawo ye-R-410A emishinini emisha, inciphisa ukusetshenziswa kwamandla ngo-10-15%.
Amaphampu Okushisa: Alungele amaphampu okushisa avela emoyeni (i-ASHP) kanye namaphampu okushisa avela emanzini (i-WSHP), ahlinzeka ngokusebenza kahle kokushisa okuzinzile ngisho nasemazingeni okushisa aphansi (-10°C kuya ku-5°C).
Izinhlelo Zokuqandisa: Zisetshenziswa eziqandisini ezincane kuya kweziphakathi, ezikhabetheni zokubonisa, nasezindaweni zokugcina izinto ezibandayo, ukuqinisekisa ukupholisa okusebenzayo okunomthelela omncane emvelweni.
Ama-Ejenti Okufutha Igwebu: Kwezinye izinqubo zezimboni, i-R-32 isebenza njenge-ejenti yokufutha amagwebu e-polyurethane aqinile, ithuthukisa izakhiwo zokuvikela igwebu.
Ukwenziwa Kwezinto Eziphilayo: Kusebenza njengezinto zokusetshenziswa ekukhiqizweni kwamakhemikhali afakwe i-fluorine, okuhlanganisa imithi kanye nama-polymer akhethekile.
Ukuphepha Nokuthobela Imithetho
Iziqondiso Zokuphepha
Ukuphatha: Gwema ukuthintana ngqo nesikhumba/amehlo; sebenzisa amagilavu okuzivikela, izibuko, kanye nemishini yokuphefumula ezindaweni ezingenawo umoya ohlanzekile.
Indawo Yokugcina: Gcina endaweni epholile, eyomile, enomoya omuhle kude namalangabi avulekile, amazinga okushisa aphezulu, kanye nezinto ezikhipha i-oxidizing. Sebenzisa izitsha ezivaliwe, ezingagqwali (isb., amasilinda ensimbi noma e-aluminium).
Ezokuthutha: Landela imithetho ye-UN yokuthuthwa kweziqandisi (inombolo ye-UN: 3252); qinisekisa ukuthi amasilinda aqiniswe kahle futhi anelebula.
Ukuthobela Imithetho
Ihlangabezana nezindinganiso ze-ASHRAE 34 (ukuhlukaniswa kokuphepha kwe-A2L).
Kuhambisana noMthethonqubo we-EU F-Gas (Umthethonqubo (EU) 2014/512), kunciphisa ukukhishwa kwegesi ye-F kanye nokukhuthaza ezinye izindlela zokusebenzisa igesi ephansi ye-GWP.
Kuvunyiwe ngabakhiqizi bemishini abakhulu (isib., iDaikin, iMitsubishi Electric, iGree) ukuze kusetshenziswe kumamodeli abo akamuva e-AC kanye ne-heat pump.
Okuvelele kweShedi Ledatha Lobuchwepheshe (i-TDS)

Kungani Kufanele Sikhethe i-Difluoromethane Yethu (R-32)?
Ukuhlanzeka Okuphezulu: Ukuhlanzeka okungaguquki okungu-99.9% kuqinisekisa ukusebenza kahle kwemishini kanye nokuphila isikhathi eside kwenkonzo.
Okuvikela Imvelo: I-GWP Ephansi (675) isekela imigomo yokungathathi hlangothi kwekhabhoni yomhlaba wonke futhi ihlangabezana nemithetho eqinile yezemvelo.
Izindleko Ezingcono: Ukusebenza kahle kakhulu kokushisa kunciphisa izindleko zamandla kubasebenzisi bokugcina, kuyilapho amakhono ethu okunikeza ngobuningi ehlisa izindleko zokuthenga.
Ukusekelwa Komhlaba Wonke: Sinikeza ukubonisana ngobuchwepheshe, ukuqeqeshwa kokuphepha, kanye nokulethwa ngesikhathi kumakhasimende emhlabeni jikelele, ngezitifiketi ezifaka phakathi i-ISO 9001 kanye ne-REACH.
