Kokoke mai ka loaʻa ʻana o nā mea pani no ka lua a me ke kolu o ka hanauna refrigerants!
Ma Sepatemaba 15, 2021, ka "Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer" i hoʻomaka i ka mana no Kina.Wahi a ka "Montreal Protocol", e pau ana ka hoʻohana ʻana o ka HCFC i ka lua o ka hoʻohana ʻana ma 2030. Pono ka hoʻololi e hiki i ka 2050, e hāʻule ka hoʻohana ʻana o ka HFC honua ma kahi o 85%.
He hanana koʻikoʻi kēia ma ke kaʻina hana hoʻopau refrigerant, a hoʻouna pū aku i kahi hōʻailona kālai'āina nui e hoʻoholo nei ke kaiāulu honua e hoʻopau i ka hoʻohana ʻana i nā HFC.
I ka manawa like, me ka hoʻokumu ʻana i ka pahuhopu "ʻelua-carbon" home a me ka hoʻokō lohi ʻana o ke kolu o ka hanauna refrigerant HFCs hoʻomalu kulekele, he mea wikiwiki e aʻo i ka HCFC, HFCs mea pani a me nā ʻenehana pili.
Hoʻokomo ka mea hoʻoheheʻe i ke au o ka waiwai GWP haʻahaʻa, a ʻaʻole hiki ke mālama ʻia ka pilikia flammability!
Ma ka ʻōlelo maʻamau, ʻo ka hoʻohana ʻana i nā mea hoʻoheheʻe flammable me nā koina GWP haʻahaʻa e pani i ka HCFC a me nā kinoea fluorine ʻē aʻe i manaʻo ʻia he hopena kūpono a haʻahaʻa.Eia nō naʻe, ua hōʻike ʻia nā haʻawina ʻaʻole hiki i nā mea hoʻoheheʻe kuʻuna ke hoʻokō i nā koi āpau o ka wā e hiki mai ana no ka GWP haʻahaʻa, ka palekana, ka hana thermodynamic a me ka hana kaiapuni i ka manawa like.
I nā huaʻōlelo ʻē aʻe, nui nā waiwai haʻahaʻa haʻahaʻa GWP hiki ke puhi ʻia!
ʻO ke kūlana aupuni "Refrigerant Numbering Method and Safety Classification" GB / T 7778-2017 e hoʻokaʻawale i nā mea ʻawaʻawa o nā refrigerants i ka papa A (haʻahaʻa haʻahaʻa haʻahaʻa) a me ka papa B (kiʻekiʻe mau meaʻawaʻawa), a ua hoʻokaʻawale ʻia ka flammability i ka Papa 1 (ʻAʻohe hoʻolaha ahi. ), Papa 2L (hiki i ka nawaliwali), Papa 2 (hiki ke hiki), a me Papa 3 (hiki i ke ahi a pahū).Wahi a GB/T 7778-2017, ua māhele ʻia ka palekana o nā mea hoʻoheheʻe i 8 mau ʻāpana, ʻo ia hoʻi: A1, A2L, A2, A3, B1, B2L, B2, a me B3.Ma waena o lākou, ʻo A1 ka palekana a ʻo B3 ka mea weliweli loa.
Pehea e hoʻohana ai i ka pahu hau A2L HFO me ka palekana a me ka maikaʻi?
ʻOiai ua hoʻāʻo ʻia nā ea ea o ka hale, nā ea kikowaena a me nā mea hoʻonaninani ʻē aʻe no ka hana ma ka hale hana, ua hōʻike ʻia ka waiwai kuhikuhi o ka uku refrigerant.Eia nō naʻe, pono e hoʻopiha ʻia ka nui o nā kikowaena ea nui a me nā chillers ʻoihana me ka refrigerant ma ka pūnaewele, e like me nā ea air conditioners, nā lako pahu hau, kahi mālama anu, a me nā mea ʻē aʻe i ka wā o ka mālama ʻana.
Eia kekahi, ma muli o ke ʻano o nā evaporators i hoʻohana ʻia i kekahi mau mea hana, ʻokoʻa ke kumukūʻai refrigerant.Ma waho aʻe o ka mālama ʻana a me ka hoʻonohonoho ʻana, ma muli o nā kūlana liʻiliʻi, nui nā limahana mālama e uku i ka refrigerant ma muli o ka ʻike.Eia kekahi, pili loa ka ʻoihana i ka pilikia o ka flammability refrigerant.
Ma muli o kēia, ua hoʻokumu ʻo Chemours iā R1234yf, R454A, R454B, R454C a me nā A2L palupalu palupalu, nā mea hoʻonā haʻahaʻa GWP haʻahaʻa, a ua kūpaʻa ʻo ia i ka hoʻolaha ʻana i ka hoʻolālā ʻōnaehana a me ka hoʻomaʻamaʻa ʻepekema kaulana e hoʻoponopono i nā pilikia flammability.
Loaʻa i ka pae palekana A2L nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa (A) a me ka palupalu palupalu (2L).Nui nā mea hoʻoheheʻe A2L HFO i loaʻa nā hiʻohiʻona kiʻekiʻe a me nā hiʻohiʻona GWP haʻahaʻa, a he mau pani kūpono no ka hanauna mua o nā mea hoʻoheheʻe HFC.ʻAʻole hoʻohana nui ʻia nā huahana A2L i ka mākeke honua, akā nui nā ʻoihana kūloko i hoʻolalelale i ka wikiwiki o ka hoʻonui ʻana a me ka hoʻokomo ʻana i kēia ʻano hou o ka refrigerant i nā noi hana.No ka laʻana, hoʻohana ʻo Johnson Controls i ka Oteon™ XL41 (R-454B) i kāna pahu chiller York ® YLAA no ka mākeke ʻEulopa;Ke koho nei ka mea lawe iā R-454B (ʻo ia hoʻi, ʻo ia ka mea hoʻoheheʻe haʻahaʻa haʻahaʻa haʻahaʻa, e hoʻohana ʻo Carrier iā R-454B i kāna mau hale kūʻai kūʻai a me nā huahana HVAC kūʻai māmā i kūʻai ʻia ma ʻAmelika ʻĀkau mai 2023. Hoʻololi iā R-410A.
