R290 refrigerant: na-ebubata n'oge ya pụta ìhè

Na 2022, refrigerant R290 mechara pụta dị ka onye na-eme ihe nkiri. N'ime ọkara mbụ nke afọ, International Electrotechnical Commission (IEC) kwetara ịgbasa oke ụgwọ ikike nke R290 na akụrụngwa zuru oke. N'etiti mmụba nke ikpo ọkụ ọkụ na Europe, R290 nwetara nlebara anya dị ukwuu na mpaghara mgbapụta okpomọkụ. N'ihu ụlọ ọrụ, kwa, enwere ọtụtụ mmepe dị mma, ebe Midea na-ebupụta ikuku ikuku R290 mbụ nke ụwa na Klas 1 Efficiency Energy.

Ka oku zuru ụwa ọnụ maka atụmatụ obere carbon na-abawanye na 2023, R290 dị njikere ịdọta nlebara anya ka ukwuu na iwebata ohere ọhụrụ maka mmepe.

R290, nke a makwaara dị ka propane, bụ ihe refrigerant nke hydrocarbon eke nwere ike nweta ya ozugbo site na gas mmanụ ọkụ. E jiri ya tụnyere refrigerants sịntetik dị ka freons, ihe owuwu molekụla R290 enweghị atom chlorine, na-eme ka uru Ozone Depletion Potential (ODP) dị efu, si otú ahụ na-ewepụ ihe ize ndụ nke mbelata oyi akwa ozone. Ọzọkwa, ma e jiri ya tụnyere ihe HFC, nke na-adịghịkwa emerụ oyi akwa ozone, R290 na-etu ọnụ ahịa Global Warming Potential (GWP) dị nso na efu, na-ebelata ihe ize ndụ nke "mmetụta griin haus."

N'agbanyeghị nzere ya na-enweghị atụ n'ihe gbasara GWP na ODP, R290 refrigerant chere esemokwu na-aga n'ihu n'ihi nhazi ya dị ka refrigerant A3 na-ere ọkụ, na-egbochi nnabata ya zuru ebe niile n'ahịa ahịa.

Agbanyeghị, 2022 wetara mgbanwe dị mma na nke a. Na Mee 2022, IEC kwuputara na webụsaịtị gọọmentị ya na nkwado nke IEC 60335-2-40 ED7, "Ihe ndị a chọrọ maka nfuli ọkụ, ikuku oyi, na dehumidifiers," ka akwadoro ọnụ. Nke a na-egosi nkwekọ n'ime ụkpụrụ IEC iji mee ka ọnụọgụ njuputa nke R290 na refrigerants ndị ọzọ na-ere ọkụ n'ime igwe ikuku ụlọ, nfuli ọkụ, na dehumidifiers.

Mgbe ị na-ajụ ajụjụ gbasara ụkpụrụ IEC 60335-2-40 ED7, Li Tingxun, onye otu prọfesọ na Mahadum Sun Yat-sen na onye otu Working Group 21, kọwara: -2-40 ED7 na-ewebata mgbanwe ndị ọzọ site n'ịtụle ọnọdụ ngwaahịa ụlọ ọrụ nwere ike ugbu a, site na itinye usoro nchekwa dị ka ịkwalite ikuku ikuku na ịnakwere atụmatụ ikuku ikuku, na-abawanye n'ụzọ ziri ezi ndochi nke A2 na A3 refrigerants, nwere ike iru elu. ruo 988g.

Mmepe a mere ka ọganihu dị ịrịba ama na ntinye nke R290 refrigerant na ụlọ ọrụ mgbapụta okpomọkụ. Nke mbu, ụkpụrụ kọmpat maka ndị na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ gụnyere ihe achọrọ maka refrigerant R290. N'ikpeazụ, na Jenụwarị 1, 2023, usoro ego gọọmentị etiti ọhụrụ nke Germany maka ụlọ akwụkwọ ndụ akwụkwọ ndụ na ike na-arụ ọrụ.

N'oge na-adịbeghị anya, a na-enwe mkparịta ụka teknuzu na-elekwasị anya na refrigerant R290 na nfuli okpomọkụ nke ọma. Emerson na Highly bụ ndị na-akwado teknụzụ R290. Na nnọkọ nnọkọ ahụ, onye nnọchite anya Emerson kwuru na ijikwa ahụmịhe ụlọ ọrụ ahụ nwere na teknụzụ refrigerant R290, ha ewepụtala usoro mpịakọta Copeland R290 compressors, na-ekpuchi ngwa ngwa, ọsọ ọsọ, kwụ ọtọ, kwụ ọtọ, na ụdị mkpọtụ dị ala, na-enye. ahaziri teknuzu ngwọta izute dị iche iche mkpa nke European okpomọkụ mgbapụta ngalaba. Eletriki dị elu, nke nwere ihe karịrị afọ iri nke ọkachamara na ngalaba mgbapụta okpomọkụ, ekpughere ọtụtụ R290 kpomkwem mgbapụta ọkụ ọkụ ahaziri maka ahịa Europe. Ngwaahịa ndị a abụghị naanị enyi na enyi na gburugburu ebe obibi kamakwa ọ na-anya isi GWP ultra-low, oke ọrụ na-arụ ọrụ, ntụkwasị obi dị elu, yana arụmọrụ, na-egbo mkpa nke ahịa mgbapụta ọkụ Europe na-akwado mgbanwe ike ndụ ndụ nke mpaghara.
