He aha ka ʻokoʻa ma waena o ka refrigerant R404a a me R507?

ʻO ka refrigerant R410A he hui ʻana o HFC-32 a me HFC-125 (50%/50% ka lakio nuipa). ʻO ka refrigerant R507 kahi refrigerant hui ʻole azeotropic non-chlorine. He kinoea kala ʻole ia ma ka mahana o ka lumi a me ke kaomi. He kinoea liquefied i hoʻopaʻa ʻia i mālama ʻia i loko o kahi cylinder kila.

TʻO ka ʻokoʻa ma waena o R404a a me R507

1. Hiki iā R507 a me R404a ke pani i ka refrigerant aloha kaiapuni o R502, akā hiki iā R507 ke piʻi i kahi mahana haʻahaʻa ma mua o R404a, kahi kūpono no nā lako hoʻoluʻu kalepa hou (nā pahu hau hau hau supermarket, nā waihona anu, nā cabinets hōʻikeʻike, ka halihali), nā lako hana hau, nā lako hoʻoluʻu halihali, nā lako hoʻoluʻu moana a i ʻole nā ​​​​lako i hoʻonui ʻia e kūpono no nā wahi āpau kahi e hiki ai iā R502 ke hana maʻamau.
2. Hōʻike ka ʻikepili ma nā ana o ke kaomi a me ka mahana o R404a a me R507 ua aneane like ke kaomi ma waena o nā mea ʻelua. Inā ʻoe e hoʻolohe mau i nā mea pono o ka ʻōnaehana i hoʻohana ʻia, e ʻike ʻoe ua kaʻana like ʻia ka wehewehe ʻana o ka lepili ma ka valve hoʻonui wela e R404a a me R507.
3. He hui ʻole-azeotropic ʻo R404A, a ua hoʻopiha ʻia i loko o kahi mokuʻāina wai, ʻoiai ʻo R507 he hui azeotropic. ʻO ke alo o R134a ma R404a e hoʻonui i ke kū'ē ʻana o ka hoʻoili nuipa a hoʻemi i ke koina wela o ke keʻena hoʻoili, ʻoiai ʻoi aku ke kiʻekiʻe o ke koina hoʻoili wela o R507 ma mua o R404a.
4. Ma muli o nā hopena hoʻohana a ka mea hana o kēia manawa, ʻoi aku ka wikiwiki o ka hopena o R507 ma mua o R404a. Eia kekahi, ua like loa ka hana o R404a a me R507. ʻOi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka mana compressor o R404a he 2.86% ma mua o R507, ʻoi aku ka kiʻekiʻe o ka mahana hoʻokuʻu o ka compressor haʻahaʻa he 0.58% ma mua o R507, a ʻoi aku ka kiʻekiʻe o ka mahana hoʻokuʻu o ka compressor kiʻekiʻe he 2.65% ma mua o R507. ʻOi aku ka kiʻekiʻe o R507 he 0.01, a ʻoi aku ka haʻahaʻa o ka mahana waena he 6.14% ma mua o R507.
5. He refrigerant azeotropic ʻo R507 me ka mahana paheʻe haʻahaʻa ma mua o R404a. Ma hope o ka liki ʻana a me ka hoʻouka ʻana i nā manawa he nui, ʻoi aku ka liʻiliʻi o ka loli ʻana o ka haku mele o R507 ma mua o R404a, ʻaʻole i loli iki ka mana hoʻoluʻu volumetric o R507, a ua hoʻemi ʻia ka mana hoʻoluʻu volumetric o R404a ma kahi o 1.6%.
6. Me ka hoʻohana ʻana i ka compressor like, ʻo ka mana hoʻoluʻu o R507 he 7%-13% ʻoi aku ka nui ma mua o R22, a ʻo ka mana hoʻoluʻu o R404A he 4%-10% ʻoi aku ka nui ma mua o R22.
7. ʻOi aku ka maikaʻi o ka hana hoʻoili wela o R507 ma mua o R404a me ka nānā ʻole inā he ʻaila lubricating a i ʻole me ka ʻole o ka ʻaila lubricating.
