ʻO 304 a me 316 SS capillary Coil Tubes mea hoʻolako i nā mea kemika china

Ua hoʻohana ʻia nā coils Microchannel no ka manawa lōʻihi i ka ʻoihana automotive ma mua o ka ʻike ʻia ʻana i nā lako HVAC i ka waena o 2000s.Mai ia manawa, ua lilo lākou i mea kaulana loa, ʻoi aku hoʻi i nā ea ea noho, no ka mea he māmā lākou, hāʻawi i ka hoʻoili wela ʻoi aku ka maikaʻi, a hoʻohana liʻiliʻi i ka refrigerant ma mua o nā mea hoʻololi wela finned tube.
Eia nō naʻe, ʻo ka hoʻohana ʻana i ka refrigerant liʻiliʻi, ʻo ia hoʻi, pono e mālama nui ʻia i ka wā e hoʻouka ai i ka ʻōnaehana me nā microchannel coils.ʻO kēia no ka mea hiki i kekahi mau auneke ke hoʻohaʻahaʻa i ka hana, ka pono, a me ka hilinaʻi o kahi ʻōnaehana hoʻomaha.

ʻO ka hoʻolālā kuʻuna finned tube coil ka maʻamau i hoʻohana ʻia i ka ʻoihana HVAC no nā makahiki he nui.Ua hoʻohana mua nā coils i nā paipu keleawe a puni me nā fins alumini, akā ua hoʻoheheʻe nā ʻōpala keleawe i ka electrolytic a me ka anthill corrosion, e alakaʻi ana i ka piʻi ʻana o ka coil leaks, wahi a Mark Lampe, ka luna huahana no nā coils umu ma Carrier HVAC.No ka hoʻoponopono ʻana i kēia pilikia, ua huli ka ʻoihana i nā paipu alumini a puni me nā fila alumini e hoʻomaikaʻi ai i ka hana ʻōnaehana a hōʻemi i ka corrosion.I kēia manawa aia kahi ʻenehana microchannel hiki ke hoʻohana ʻia i nā evaporators a me nā condensers.
"ʻOkoʻa ka ʻenehana microchannel, i kapa ʻia ʻo ka ʻenehana VERTEX ma Carrier, i kēlā mau paipu alumini poepoe i hoʻololi ʻia me nā paipu parallel palahalaha i kūʻai ʻia i nā fins alumini," wahi a Lampe."Ke hāʻawi like nei kēia i ka refrigerant ma kahi ākea, hoʻomaikaʻi i ka hoʻoili wela i hiki ai i ka coil ke hana pono.ʻOiai ua hoʻohana ʻia ka ʻenehana microchannel i nā condensers o waho o ka hale, ua hoʻohana ʻia ka ʻenehana VERTEX i kēia manawa i nā coils noho.
Wahi a Jeff Preston, ka luna o nā lawelawe ʻenehana ma Johnson Controls, hoʻokumu ka hoʻolālā microchannel i kahi kahe hoʻoheheʻe maʻalahi "i loko a i waho" i loaʻa i kahi paipu wela ma luna a me kahi paipu subcooled ma lalo.I ka hoʻokaʻawale ʻana, kahe ka mea hoʻoheheʻe i loko o ka ʻili puʻupuʻu finned maʻamau ma nā ala he nui mai luna a lalo i ke ʻano serpentine, e koi ana i kahi ʻāpana ʻili.
"ʻO ka hoʻolālā coil microchannel kūikawā e hāʻawi i ka coefficient hoʻoili wela maikaʻi loa, e hoʻonui ai i ka pono a hoʻemi i ka nui o ka refrigerant e pono ai," wahi a Preston."ʻO ka hopena, ʻoi aku ka liʻiliʻi o nā mea i hoʻolālā ʻia me nā microchannel coils ma mua o nā mea hana kiʻekiʻe me nā hoʻolālā finned tube kuʻuna.He kūpono kēia no nā noi i hoʻopaʻa ʻia e like me nā hale me nā laina ʻole.
ʻOiaʻiʻo, mahalo i ka hoʻokomo ʻia ʻana o ka ʻenehana microchannel, wahi a Lampe, ua hiki iā Carrier ke mālama i ka nui o nā coils umu ahi i loko a me nā condensers ea hoʻoheheʻe waho i ka nui like ma ka hana ʻana me ka hoʻolālā ʻili a me ka paipu.
"Inā ʻaʻole mākou i hoʻokō i kēia ʻenehana, pono mākou e hoʻonui i ka nui o ka wili umu i loko i 11 iniha ke kiʻekiʻe a pono e hoʻohana i kahi chassis nui no ka condenser waho," wahi āna.
ʻOiai ke hoʻohana mua ʻia nei ka ʻenehana coil microchannel i loko o ka refrigeration home, ke hoʻomaka nei ka manaʻo e hopu i nā mea kūʻai aku e like me ke koi ʻana no ka māmā, ʻoi aku ka nui o nā lako paʻa e hoʻomau nei, wahi a Preston.
Ma muli o ka liʻiliʻi liʻiliʻi o ka mea hoʻoheheʻe microchannel coils, hiki i kekahi mau auneke o ka hoʻololi ʻana ke hoʻololi i ke ola ʻōnaehana, ka hana a me ka pono o ka ikehu, wahi a Preston.ʻO ia ke kumu e nānā mau ai ka poʻe ʻelike me ka mea hana e pili ana i ke kaʻina hana hoʻopiʻi, akā maʻamau e pili ana i nā pae aʻe:
Wahi a Lampe, kākoʻo ka ʻenehana Carrier VERTEX i ke kaʻina hana hoʻonohonoho like, uku a me ka hoʻomaka ʻana e like me ka ʻenehana pahu puni a ʻaʻole koi i nā ʻanuʻu i hoʻohui ʻia a ʻokoʻa paha i ke kaʻina hana ʻoluʻolu i kēia manawa.
"Ma kahi o 80 a 85 ka nui o ka uku i loko o ke kūlana wai, no laila ma ke ʻano hoʻoluʻu aia ka leo i loko o ka condenser coil a me ka laina laina," wahi a Lampe."I ka neʻe ʻana i nā coils microchannel me ka liʻiliʻi o loko (hoʻohālikelike ʻia me nā hoʻolālā fin tubular fin), ʻo ka ʻokoʻa o ka hoʻopiʻi e pili wale ana i ka 15-20% o ka nui o ka uku, ʻo ia hoʻi kahi kahua liʻiliʻi a paʻakikī.ʻO ia ke kumu i manaʻo ʻia e hoʻopaʻa i ka ʻōnaehana ma ka subcooling, kikoʻī i kā mākou ʻōlelo hoʻonohonoho.
Eia nō naʻe, hiki i ka liʻiliʻi o ka refrigerant i loko o nā microchannel coils ke lilo i pilikia i ka wā e hoʻololi ai ka ʻāpana wela o waho i ke ʻano wela, wahi a Lampe.Ma kēia ʻano, ua hoʻololi ʻia ka wili ʻōnaehana a ʻo ka capacitor e mālama i ka hapa nui o ka hoʻopiʻi wai i kēia manawa ʻo ia ka coil kūloko.
"Ke emi loa ka nui o loko o ka coil i loko ma mua o ka coil waho, hiki ke loaʻa kahi helu ʻole i ka ʻōnaehana," wahi a Lampe."No ka hoʻoponopono ʻana i kekahi o kēia mau pilikia, hoʻohana ʻo Carrier i kahi pākaukau i kūkulu ʻia i loko o ka ʻāpana waho e hoʻokahe a mālama i ka uku keu ma ke ʻano hoʻomehana.ʻAe kēia i ka ʻōnaehana e mālama i ke kaomi kūpono a pale i ka compressor mai ke kahe ʻana, hiki ke alakaʻi i ka hana maikaʻi ʻole no ka mea hiki ke kūkulu ʻia ka aila i loko o ka coil kūloko.
ʻOiai ʻo ka hoʻouka ʻana i kahi ʻōnaehana me nā microchannel coils hiki ke koi i ka nānā kūikawā i nā kikoʻī, ʻo ka hoʻopiʻi ʻana i kekahi ʻōnaehana HVAC pono e hoʻohana pololei i ka nui o ka refrigerant, wahi a Lampe.
"Inā nui ka ʻōnaehana, hiki iā ia ke alakaʻi i ka hoʻohana ʻana i ka mana kiʻekiʻe, ka hoʻoluʻu ʻole ʻana, nā leaks a me ka hemahema o ka compressor premature," wahi āna."Pēlā hoʻi, inā he haʻahaʻa ka ʻōnaehana, coil freezing, expansion valve vibration, compressor hoʻomaka pilikia a me nā pani hoʻopunipuni.ʻAʻole ʻokoʻa nā pilikia me nā microchannel coils.
Wahi a Jeff Preston, ka luna o nā lawelawe ʻenehana ma Johnson Controls, hiki ke paʻakikī ka hoʻoponopono ʻana i nā coils microchannel ma muli o kā lākou hoʻolālā kū hoʻokahi.
"Pono ka hoʻoheheʻe ʻana i ka ʻili i nā lama a me ka MAPP gas i hoʻohana ʻole ʻia i nā ʻano mea hana ʻē aʻe.No laila, nui nā mea ʻaelike e koho e hoʻololi i nā coils ma mua o ka hoʻāʻo e hoʻoponopono.
I ka hoʻomaʻemaʻe ʻana i nā coils microchannel, ʻoi aku ka maʻalahi, wahi a Mark Lampe, ka mea hoʻokele huahana no nā wili umu ma Carrier HVAC, no ka mea, ʻoi aku ka maʻalahi o nā ʻili alumini o nā wili pahu finned.ʻO ka nui o nā ʻeke ʻeke e hōʻemi i ka nui o ka ea e hele ana i loko o ka coil, e hōʻemi ana i ka pono.
"He hoʻolālā ʻoi aku ka ikaika o ka ʻenehana Carrier VERTEX no ka mea e noho liʻiliʻi ana nā ʻuala alumini ma lalo o nā paipu hoʻoheheʻe alumini palahalaha a ua hoʻopaʻa ʻia i nā paipu, ʻo ia hoʻi ʻaʻole e hoʻololi nui ka palaki ʻana i nā hope," wahi a Lampe.
Hoʻomaʻemaʻe maʻalahi: I ka hoʻomaʻemaʻe ʻana i nā coils microchannel, e hoʻohana wale i nā mea hoʻomaʻemaʻe coil non-acidic a i ʻole, i nā manawa he nui, i ka wai wale nō.(hāʻawi ʻia e ka mea lawe)

"Akā naʻe, pono ka liʻiliʻi o ka refrigerant i kekahi mau hoʻololi i ka hana mālama," i ʻōlelo ai ʻo ia."No ka laʻana, ma muli o ka liʻiliʻi liʻiliʻi, ʻaʻole hiki ke puhi ʻia ka refrigerant i ka wā e pono ai nā ʻāpana ʻē aʻe o ka ʻōnaehana.Eia kekahi, pono e hoʻopili wale ʻia ka mea hana i ka wā e pono ai e hōʻemi i ka hoʻopau ʻana o ka nui o ka refrigerant.
Ua hoʻohui ʻo Preston e hoʻohana ana ʻo Johnson Controls i nā kūlana koʻikoʻi ma kāna kahua hōʻike Florida, kahi i hoʻoulu ai i ka hoʻomohala ʻana o nā microchannels.
"ʻO nā hopena o kēia mau hoʻāʻo e ʻae iā mākou e hoʻomaikaʻi i kā mākou hoʻomohala huahana ma o ka hoʻomaikaʻi ʻana i kekahi mau alloys, nā mānoanoa paipu a me nā kemika i hoʻomaikaʻi ʻia i ke kaʻina hana brazing lewa e hoʻopaʻa ʻia i ka corrosion coil a hōʻoia i nā pae kūpono o ka hana a me ka hilinaʻi e hoʻokō ʻia," wahi āna."ʻO ka lawe ʻana i kēia mau hana ʻaʻole e hoʻonui wale i ka ʻoluʻolu o ka mea hale, akā e kōkua pū kekahi i ka hōʻemi ʻana i nā pono mālama."
