Difluoromethane (R-32) ni ikintu kitagira ibara, kitagira ubumara, kandi gishobora kwaka gatoyi, gifise ubushobozi bwiza cane bwo gutera ubushuhe. Kubera ko ari igikoresho co gukonjesha c’uruvyaro rukurikira kidahungabanya ibidukikije, caracitse uburyo nyamukuru bwo gusubirira ibikoresho vya kera vy’ugukonjesha bifise ubushuhe bwinshi (GWP (Global Warming Potential), vyemewe cane kubera uburinganire bwavyo bw’ubushobozi, umutekano, n’ukubungabunga ibidukikije.
Ibiranga urufunguzo
| Umutungo | Ibisobanuro | Akarusho |
| Igikoresho co guteka (ku 1 atm) | -51,6°C (-60,9°F) | Bishoboza gutanga ubushuhe neza mu bikorwa vy'ubushuhe buke |
| GWP (Ubushobozi bwo Gushuha kw'Isi, 100 - umwaka) | 675 | Ivyo bikaba bigabanya cane ikirenge c’umuyagankuba . |
| ODP (Ubushobozi bwo Gutakaza Ozone) | 0 | Ntaco yonona ku gice ca ozone, bihuye n'amabwirizwa mpuzamakungu agenga ibidukikije (nk'akarorero, amasezerano ya Montreal) |
| Ubushuhe bukomeye | 78,1°C (172,6°F) | Ibereye ku bikoresho vyo gukonjesha umuyaga n'ivyo gupompa ubushuhe bikoreshwa mu bidukikije bifise ubushuhe buringaniye canke burengeye |
| Ugusha | Ishobora kwaka gatoyi (A2L ku ASHRAE 34) | Ni vyiza ku bikorwa vyinshi vyo kubamwo no mu bucuruzi bifise umubumbe mwiza |
| Ugutwara ubushuhe | Hejuru (kuruta R - 410A) | Yongera ubushobozi bwo gukonjesha/gushushanya, kugabanya ingufu zikoreshwa n'ibikoresho |
Ibikorwa bisanzwe
R-32 ikoreshwa cane mu bikorwa bitandukanye vy’inganda n’ivy’abaguzi kubera ubushobozi bwayo bwiza cane n’ivyiza biva ku bidukikije:
Ivyuma bikoreshwa mu gukonjesha umuyaga mu nzu no mu bikorwa vy’ubudandaji: Nk’ivyuma bikoreshwa mu gukonjesha vy’intango ku bikoresho vy’umuyaga bifise ubwoko butandukanye, ivyuma vy’umuyaga vyo mu madirisha, n’ibikoresho vya VRV (Variable Refrigerant Volume). Isubirira R-410A mu bikoresho bishasha, igabanya ikoreshwa ry’inguvu n’ibice 10-15%.
Amapompo y’ubushuhe: Ni meza cane ku mapompo y’ubushuhe akomoka ku kirere (ASHPs) no ku mapompo y’ubushuhe akomoka ku mazi (WSHPs), atanga ubushuhe buhamye mbere no mu bushuhe buke (-10°C gushika kuri 5°C).
Uburyo bwo Gukonjesha: Bikoreshwa mu mafirigo mato canke aringaniye, mu bikoresho vyo kwerekaniramwo ibintu be no mu bikoresho vyo kubika ibintu bikonje, bikaba bituma umuntu akonjera neza ataco akora ku bidukikije.
Ivyo Gufuha Ifu: Mu bikorwa bimwebimwe vy’inganda, R-32 ikora nk’igikoresho co gufuha amafu akomeye ya polyurethane, bigatuma ifu igira ubushobozi bwo kwikingira.
Ivyiyumviro vy’ibinyabuzima: Bikora nk’igikoresho nyamukuru mu guhingura imiti irimwo fluorine, harimwo n’imiti n’ibindi bihimba vy’umubiri vy’umwihariko.
Umutekano n'Ukugendera
Amabwirizwa y'umutekano
Uko wobifata: Irinde gukorana n’urukoba/amaso; gukoresha amaganzu yo kwikingira, amataratara be n’ibikoresho vyo guhema mu bibanza bitagira umwuka mwiza.
Uko ubibika: Bibike ahantu hakanye, humye, harimwo umwuka mwiza, kure y’umuriro, ubushuhe bwinshi be n’ibintu bitera umwuka. Koresha ibikoresho bipfutse, bishobora gusenyuka (nk’akarorero, ivyuma canke ivyuma vy’aluminiyumu).
Ugutwara: Kubahiriza amabwirizwa y’ishirahamwe mpuzamakungu ONU yerekeye gutwara ibikoresho vy’isuku (inomero ya ONU: 3252); kumenya neza ko amacylindre afashwe neza kandi afise amazina.
Kubahiriza amategeko
Ihuye n’ingingo ngenderwako za ASHRAE 34 (Igice c’umutekano ca A2L).
Ivyubahiriza Itegeko ry’Ubumwe bw’Uburayi ryerekeye Gazi F (Itegeko (EU) 2014/512), rigabanya ivyuka F-gaz no guteza imbere uburyo bundi bwo gukoresha GWP ntoyi.
Yemejwe n’abahinguzi b’ibikoresho bakuru (nk’akarorero, Daikin, Mitsubishi Electric, Gree) kugira ngo bikoreshwe mu bikoresho vyabo bishasha vy’amashanyarazi n’ivy’ubushuhe.
Urupapuro rw'amakuru y'ubuhinga (TDS) Ibintu bihambaye
| Imirongo | Igiciro | Uburyo bwo kugerageza |
| Ubusuku (min) | 99.9% | GC (Ibara ry'umuyagankuba) |
| Ibirimwo ubukonje (birenze) | 10 ppm | Ugupima kwa Karl Fischer |
| Ibirimwo aside (birenze) | 0.1 ppm | Gupima |
| Amasigarira adashobora guhungabana (max) | 10 mg/ikilo | Gupima uburemere bw'isi |
| Inguvu z'umwotsi (ku 25°C) | 1.72 MPa | Igipima umuvuduko |
Ni kubera iki duhitamwo igikoresho cacu c’ivyuma (R-32)?
Ubusuku buhambaye: Ubusuku buhoraho bwa 99,9% buratuma ibikoresho bikora neza kandi bikamara igihe kirekire.
Ivyiza vy’ibidukikije: GWP ntoyi (675) ishigikira intumbero z’ukutagira aho zigarukira kw’isi yose kandi ihuye n’amategeko akomeye agenga ibidukikije.
Igiciro-Ciza: Ubushuhe bwinshi bugabanya igiciro c’inguvu ku bakoresha, mu gihe ubushobozi bwacu bwo gutanga ibikoresho vyinshi bugabanya igiciro c’ugugura.
Infashanyo kw’isi yose: Turatanga impanuro z’ubuhinga, inyigisho z’umutekano, n’ugushikana ibifungurwa ku gihe ku bakiriya bo kw’isi yose, dufise ivyemezo birimwo ISO 9001 na REACH.
