He mau kakini o nā koho refrigerant i kūʻai ʻia ma ka mākeke i kēia lā, me ka hui pū ʻana o ka refrigerant he nui, kahi e manaʻo ai e hoʻihoʻi i ka maikaʻi o nā hana hana mua e like me R22, ʻo ia ka mea i hana ʻole ʻia ma Ianuali o kēia makahiki. ʻElua laʻana kaulana o nā mea hoʻoheheʻe i hoʻomohala ʻia i nā makahiki he 30 i hala a i ʻole i hoʻohana ʻia ma ka ʻoihana HVAC ʻo R-410A a me R-407C. Hoʻohana pinepine ʻia kēia mau mea hoʻoheheʻe ʻelua no nā noi like, akā loaʻa iā lākou kekahi mau ʻokoʻa e pono e hoʻomaopopo a noʻonoʻo ʻia i ka wā e hoʻoholo ai ma waena o lākou.
R-407C
Hana ʻia e ka hui ʻana o R-32, R-125, a me R-134a, ʻo R-407C kahi hui zeotropic, ʻo ia hoʻi, ʻo kona mau mea i hoʻolapalapa ʻia i nā mahana like ʻole. Hoʻohana ʻia nā mea i loko o R-407C no ka hoʻonui ʻana i nā hiʻohiʻona i makemake ʻia, me ka R-32 e hāʻawi ana i ka mana wela, R-125 e hāʻawi i ka haʻahaʻa haʻahaʻa, a me R-134a e hoʻemi i ke kaomi.
ʻO kahi pōmaikaʻi o ka hoʻohana ʻana iā R-407C ma nā kūlana kiʻekiʻe-ambient ʻo ia ka hana ʻana ma ke kaomi haʻahaʻa. Eia naʻe, hoʻokahi drawback e nānā, ʻo ka holo ʻana o R-407C o 10°F. No ka mea R-407C he hui zeotropic, glide ka ʻokoʻa wela ma waena o nā wahi paila ʻekolu. ʻOiai ʻaʻole like ka nui o nā degere he ʻumi, hiki ke loaʻa nā hopena maoli i nā mea ʻē aʻe o kahi ʻōnaehana.
Hiki i kēia holo ʻana ke hoʻopōʻino i ka hana ʻana o kahi ʻōnaehana ma kahi kūlana kiʻekiʻe, ma muli o ke kokoke kokoke ʻana i ka mahana ma waena o ka wahi condensing o ka mea hoʻoheheʻe condensing hope loa a me ke kahe ea. ʻO ka hoʻonui ʻana i ka mahana condensing ʻaʻole ia he koho maikaʻi, ma muli o ka nui o ka hoʻokuʻu ʻana i ʻae ʻia no ka compressor. No ka uku ʻana i kēia, pono e ʻoi aku ka nui o kekahi mau ʻāpana e like me condenser coils a i ʻole condenser fans, e hele mai me ka nui o nā manaʻo, ʻoi aku ka nui o ke kumukūʻai.
R-410A
E like me R407C, ʻo R-410A kahi hui zeotropic, a hana ʻia ma ka hui ʻana iā R-32 a me R-125. I ka hihia o R-410A, akā naʻe, he liʻiliʻi loa kēia ʻokoʻa ma waena o ko lākou mau wahi paila ʻelua, a ua manaʻo ʻia ka refrigerant kokoke i ka azeotropic. ʻO nā Azeotropes nā hui pū me kahi helu hoʻolapalapa mau, ʻaʻole hiki ke hoʻololi ʻia nā ʻāpana o ia mea ma ke ʻano o ka distillation.
He mea kaulana loa ʻo R-410A no nā noi HVAC, e like me nā condensers. Eia nō naʻe, i nā mahana ambient kiʻekiʻe, ʻoi aku ka kiʻekiʻe o ka hana o R-410A ma mua o R-407C, e alakaʻi ana i kekahi e noʻonoʻo i nā koho ʻē aʻe no ia mau noi. ʻOiai ʻoi aku ka kiʻekiʻe o ka hana ʻana o R-410A ma nā mahana ambient kiʻekiʻe ma mua o ka R-407C, ma Super Radiator Coils, hiki iā mākou ke hana i nā hopena UL-listed e hoʻohana ana iā R-410A a hiki i 700 PSIG, e lilo ia i mea piha loa. palekana a maikaʻi hoʻi ka refrigerant no nā piʻi wela.
He mea kaulana loa ʻo R-410A no ka ea ea noho a me ka ʻoihana ma kekahi mau mākeke, me ʻAmelika Hui Pū ʻIa, ʻEulopa, a me nā ʻāpana o Asia. ʻO ka haʻalulu e pili ana i kona kaomi hana kiʻekiʻe i nā mahana wela wela e wehewehe i ke kumu o ka nui ʻole o R-410A ma nā wahi e like me ka Middle East a i ʻole nā wahi wela o ka honua.
