Difluoromethane
Kulanga-langa zintu
Zina lyamakemikalu: Difluoromethane
Namba ya CAS: 75-10-5
Fomula ya Molekyula: CH2F2
Kulema kwamolekyula: 52.02 g/mol�
Izina lizyibidwe: R-32 (mbuli chintu chitontola)
Difluoromethane (R-32) nchintu chitakwe mubala, chitakwe bbivwe, mpawo chikonzya kupya mbichani (HFC) chibeleka obotu loko. Mbuli chintu chitontola chazyalani litobela litanyonganyi busena, chaba chintu chipati chikonzya kubelesegwa mubusena bwama refrigerant aakaindi aajisi GWP (Global Warming Potential), aazyibidwe kapati akaambo kakuchita obotu, lukwabililo, akukwabilila busena.
Zintu Zipati
| Lubono | Kusalazya | Bubotu bwechintu |
| Busena bwakubila (a 1 atm) | -51.6°C (-60.9°F) | Zipa kuti kube kweenda kabotu kwakupya mumasena aatakwe kupya kapati |
| GWP (Kupya Kwanyika Yoonse, 100 - mwaka) | 675 | Munsi loko kwiinda R - 410A (GWP = 2088) antoomwe a R - 22 (GWP = 1810), ikucheesya muya uuzwa mumulengalenga |
| ODP (Kumana kwa Ozone) | 0 | Kunyina kunyonyooka kwa ozone layer, kweendelana amilawu yanyika yoonse iilanganya busena (nkokuti, Montreal Protocol) |
| Kupya Kupati | 78.1°C (172.6°F) | Chili kabotu kubelesyegwa kutontozya muuya antoomwe amapompi aapya aabeleka mumasena aapya kapati |
| Kupya | Zilakonzya kupya mbichaani (A2L classification kweendelanya a ASHRAE 34) | Zili kabotu mumaanda manji amumabbindawuko kazipangidwe kabotu |
| Kutola Kupya | Mujulu (kubotu kwiinda R - 410A) | Kusumpula kutontozya/kupya kabotu, kuchesya kubelesya manguzu aazibelesyo |
Kubelesya kwachiindi choonse
R-32 ilabelesyegwa kapati mumakwebo aasiyene-siyene alimwi abasikuula akaambo kakubeleka kwayo kubotu alimwi akugwasya busena:
Kutontozya muya mumaanda amumabbindawuko: Mbuli chintu chitontozya kapati kuma AC aajisi musyobo waandeene, ma AC aawindo, antoomwe a VRV (Variable Refrigerant Volume) systems. Ilanjila mubusena bwa R-410A muzibelesyo zipya, ikugwisya kubelesya manguzu a 10-15%.
Mapompi Aapya: Mabotu kapati kumapompi aapya aazwa mumuwo (ASHPs) alimwi amapompi aapya aazwa kumaanzi (WSHPs), aagwasya kupya kutazungaani nokuba kuti kuli kupya kusyoonto (-10°C kusikila ku 5°C).
Nzila zyakutontozya: Zibelesyegwa mumafiriji masyoonto kusikila aakati-akati, mumabbokesi aatondezya zintu, amumasena aakuyobweda zintu zitontola, kusinizya kuti kutontola kabotu kakunyina kunyonganya busena.
Zibelesyo Zyakufwusa Foomu: Munzila zimwi zyakupanga zintu, R-32 ibelekela mbuli musamu wakufwusa mafoomu aa polyurethane, akusumpula bube bwakukwabilila foomu.
Kupanga zintu zipona: Kubeleka mbuli chintu chibelesegwa mukupanga makemikalu aajisi fluorine, kubikkilizya amisamu alimwi ama polymers aalibedelede.
Lukwabililo akutobela milawu
Malailile aakukwabilila
Kujata: Kotantamuka kuguma chikumba/meso; belesya magilovu aakulikwabilila, magilazi, azibelesyo zyakuyoya mumasena aatakwe muya mubotu.
Kubamba: Kobamba mubusena butontola, butakwe maanzi, bujisi muya mubotu kule amulilo uuyaka, kupya kapati, azintu zipa kuti kube muya. Belesya zibelesyo zijalilidwe, zitanyonyooki (nkokuti, zibulo zyabutale naa aluminiyamu).
Zyakweenzya: Tobelezya milawu ya UN yakweenzya zintu zitontola (namba ya UN: 3252); sinizya kuti masilinda akwabilidwe kabotu akulembwa.
Kutobela milawu
Ilazuzikizya zyeelelo zya ASHRAE 34 (A2L safety classification).
Kutobelezya mulawu wa EU F-Gas (Mulawu (EU) 2014/512), kucesya kuzwa kwa F-gas akusumpula nzila zimbi zitabelesyi GWP.
Zyakazumizigwa abasikupanga zibelesyo zipati (nkokuti, Daikin, Mitsubishi Electric, Gree) kuti zibelesyegwe muma AC amapompi aabo mapya.
Pepa lyamakani aabusongo (TDS) Twaambo Tupati
| Paramita | Bulemu | Nzila Yakusunka |
| Kusalala (miniti) | 99.9% | GC (Gas Chromatography) |
| Buteteete (max) | 10 ppm | Karl Fischer Titration |
| Asidi iili mukati (max) | 0.1 ppm | Kuyungizya |
| Zisyaala Zitazungaani (max) | 10 mg/kg | Gravimetry |
| Kuyuma kwamuwo (a 25°C) | 1.72 MPa | Chipimyo changuzu |
Nkaambo nzi ncotweelede kusala Difluoromethane yesu (R-32)?
Kusalala Kupati: Kusalala kutamani kwa 99.9% kupa kuti zibelesyo zibeleke kabotu akuti zibeleke kwachiindi chilamfu.
Kuchita zintu zitanyonganyi busena: GWP nsyoonto (675) ilagwasyilizya mbaakani zyakukwabilila busena bwanyika yoonse mpawo ilazuzikizya milawu miyumu yakukwabilila busena.
Kubelesya mali masyoonto: Kubelesya kabotu mulilo kulacesya muulo wamanguzu kuli baabo babelesya, mpawo nguzu zyesu zyakusambala zinji zilacesya muulo wakuula.
Lugwasyo lwanyika yoonse: Tulapa lulayo lwazyabusongo, lwiiyo lwabukwabilizi, akutola zintu muchiindi cheelede kuli basikuula nyika yoonse, katujisi zipepa zyakuzumizya zibikkilizya ISO 9001 antoomwe a REACH.
