ʻO Difluoromethane
ʻIke Huahana
Inoa Kemika: Difluoromethane
Helu CAS: 75-10-5
Formula Molekala: CH₂F₂
Kaumaha Molekala: 52.02 g/mol
Inoa Maʻamau: R-32 (ma ke ʻano he refrigerant)
ʻO Difluoromethane (R-32) he hydrofluorocarbon (HFC) ʻaʻohe kala, ʻaʻohe ʻawahia, a he ʻā iki hoʻi me ka hana wela maikaʻi loa. Ma ke ʻano he refrigerant eco-friendly hanauna hou, ua lilo ia i mea koho koʻikoʻi i nā refrigerants GWP kiʻekiʻe kuʻuna (Global Warming Potential), i ʻike nui ʻia no kona kaulike o ka pono, ka palekana, a me ke aloha i ke kaiapuni.
Nā Waiwai Koʻikoʻi
| Waiwai | Nā kikoʻī | Pōmaikaʻi |
| Kikowaena paila (ma 1 atm) | -51.6°C (-60.9°F) | Hoʻāla i ka hoʻoili wela kūpono i nā noi haʻahaʻa haʻahaʻa |
| GWP (Ka Mana Hoʻomehana Honua, 100 - makahiki) | 675 | ʻOi aku ka haʻahaʻa ma mua o R - 410A (GWP = 2088) a me R - 22 (GWP = 1810), e hōʻemi ana i ka kapuaʻi kalapona |
| ODP (Ka Mana Hoʻopau ʻOzone) | 0 | ʻAʻohe hōʻino i ka papa ozone, kūlike me nā lula kaiapuni honua (e laʻa, Montreal Protocol) |
| Mahana Koʻikoʻi | 78.1°C (172.6°F) | Kūpono no nā ʻōnaehana ea hoʻoluʻu a me ka pamu wela e hana ana i nā wahi mahana waena a kiʻekiʻe |
| Ka lapalapa ʻana | ʻAʻā iki (hoʻokaʻawale ʻana o A2L e like me ASHRAE 34) | Palekana no ka hapa nui o nā noi noho a me nā ʻoihana me ka hoʻolālā kūpono |
| Ka Hoʻokele Wela | Kiʻekiʻe (ʻoi aku ka maikaʻi ma mua o R - 410A) | Hoʻonui i ka pono o ka hoʻoluʻu/hoʻomehana ʻana, e hōʻemi ana i ka hoʻohana ʻana i ka ikehu o nā lako |
Nā Hoʻohana Maʻamau
Hoʻohana nui ʻia ʻo R-32 ma nā ʻāpana ʻoihana a me nā mea kūʻai aku ma muli o kāna hana kiʻekiʻe a me nā pono kaiapuni:
Ea Hoʻoluʻu Noho a me nā ʻOihana: Ma ke ʻano he mea hoʻomaʻalili mua no nā ʻāpana AC ʻano māhele, nā AC puka makani, a me nā ʻōnaehana VRV (Variable Refrigerant Volume). Hoʻololi ia iā R-410A i nā lako hou, e hōʻemi ana i ka hoʻohana ʻana i ka ikehu ma 10-15%.
Nā Pamu Wela: Kūpono no nā pamu wela kumu ea (ASHP) a me nā pamu wela kumu wai (WSHP), e hāʻawi ana i ka hana hoʻomehana paʻa ʻoiai ma nā mahana haʻahaʻa (-10°C a 5°C).
Nā ʻōnaehana hoʻomaʻalili: Hoʻohana ʻia i loko o nā pahu hau liʻiliʻi a waena, nā pahu hōʻikeʻike, a me nā ʻāpana mālama anu, e hōʻoiaʻiʻo ana i ka hoʻomaʻalili maikaʻi me ka hopena liʻiliʻi i ke kaiapuni.
Nā Mea Puhi Huʻa: Ma kekahi mau kaʻina hana ʻoihana, hana ʻo R-32 ma ke ʻano he mea puhi no nā huʻa polyurethane paʻa, e hoʻomaikaʻi ana i nā waiwai insulation huʻa.
Hana Organic: Lawelawe ma ke ʻano he mea maka i ka hana ʻana o nā kemika fluorinated, me nā lāʻau lapaʻau a me nā polymers kūikawā.
Palekana a me ka Hoʻokō
Nā Alakaʻi Palekana
Ka lawelawe ʻana: E pale i ka pili pololei ʻana me ka ʻili/maka; e hoʻohana i nā mīkina lima pale, nā goggles, a me nā lako hanu ma nā wahi i nele i ka ea.
Ka Mālama ʻana: E mālama i kahi maloʻo, kahi ea maikaʻi, kahi mamao aku mai nā lapalapa ahi, nā mahana kiʻekiʻe, a me nā mea hoʻoheheʻe oxidizing. E hoʻohana i nā ipu i hoʻopaʻa ʻia a pale i ka pala (e like me nā cylinders kila a alumini paha).
Ka Halihali: E mālama i nā lula o ka UN no ka lawe ʻana i nā refrigerants (helu UN: 3252); e hōʻoia i ka hoʻopaʻa pono ʻia ʻana o nā cylinders a me ka lepili ʻia.
Hoʻokō kānāwai
Kū i nā kūlana ASHRAE 34 (ka hoʻokaʻawale palekana A2L).
Kūlike me ke Kānāwai F-Gas EU (Regulation (EU) 2014/512), e kaupalena ana i nā hoʻokuʻu ʻana o ke kinoea F a me ka hoʻolaha ʻana i nā koho ʻē aʻe GWP haʻahaʻa.
Ua ʻāpono ʻia e nā mea hana lako nui (e laʻa me Daikin, Mitsubishi Electric, Gree) no ka hoʻohana ʻana i kā lākou mau hiʻohiʻona AC a me ka pamu wela hou loa.
Nā mea nui o ka pepa ʻikepili loea (TDS)
| Palena | Waiwai | ʻAno Hoʻāʻo |
| Maʻemaʻe (min) | 99.9% | GC (Kromatografi Kinoea) |
| Ka nui o ka wai (max) | 10 ppm | Ka Hoʻohālikelike ʻana o Karl Fischer |
| Ka nui o ka waikawa (max) | 0.1 ppm | Titration |
| Koena ʻAʻole - Volatile (max) | 10 mg/kg | Gravimetry |
| Kaomi mahu (ma 25°C) | 1.72 MPa | Ana Paʻi |
No ke aha e koho ai i kā mākou Difluoromethane (R-32)?
Maʻemaʻe Kiʻekiʻe: ʻO ka maʻemaʻe mau o 99.9% e hōʻoiaʻiʻo ana i ka hana paʻa o nā lako a me ke ola lawelawe lōʻihi.
ʻO Eco-Friendly: Kākoʻo ka GWP haʻahaʻa (675) i nā pahuhopu kūlike ʻole o ke kalapona honua a hoʻokō i nā lula kaiapuni koʻikoʻi.
Kumukūʻai Kūpono: ʻO ka hoʻohana ʻana i ka wela kiʻekiʻe e hōʻemi ana i nā kumukūʻai ikehu no nā mea hoʻohana hope, ʻoiai ʻo kā mākou hiki ke hoʻolako nui e hoʻemi i nā kumukūʻai kūʻai.
Kākoʻo Honua: Hāʻawi mākou i ke kūkākūkā loea, ke aʻo palekana, a me ka hoʻouna ʻana i ka manawa kūpono i nā mea kūʻai aku ma ka honua holoʻokoʻa, me nā palapala hōʻoia e pili ana iā ISO 9001 a me REACH.
Kāhea iā mā˚ou
No ke kumukūʻai, nā laʻana, a i ʻole nā palapala TDS/COA piha, e hoʻokaʻaʻike aku i kā mākou hui kūʻai aku:
