Gariiradaha Microchannel ayaa muddo dheer loo isticmaali jiray warshadaha baabuurta ka hor inta aysan ka soo muuqan qalabka HVAC bartamihii 2000-meeyadii.Tan iyo markaas, waxay noqdeen kuwo caan ah, gaar ahaan qaboojiyaha la deggan yahay, sababtoo ah way fudud yihiin, waxay bixiyaan kulaylka wanaagsan, waxayna isticmaalaan qaboojiye ka yar kuwa kuleyliyaha dhaqameed ee fined.
Si kastaba ha noqotee, isticmaalka qaboojiye yar sidoo kale waxay la macno tahay in taxadar badan la sameeyo marka nidaamka lagu dalaco gariiradaha microchannel.Tani waa sababta oo ah xitaa dhowr wiqiyadood ayaa hoos u dhigi kara waxqabadka, hufnaanta, iyo kalsoonida nidaamka qaboojinta.

Naqshadaynta gariiradda tubbada ee dhaqameedku waxay ahayd heerka lagu isticmaalo warshadaha HVAC sanado badan.Gariiradu waxay markii hore isticmaali jireen tuubooyinka naxaasta wareegsan oo leh baalal aluminium ah, laakiin tuubooyinka naxaasta ah waxay sababeen daxalka korantada iyo qudhaanjada, taasoo keentay kororka gariiradda dillaacsan, ayuu yidhi Mark Lampe, maamulaha alaabada gariiradda foornada ee Carrier HVAC.Si loo xalliyo dhibaatadan, warshaduhu waxay u jeesteen inay wareegaan tuubooyinka aluminiumka leh aluminium aluminium si loo hagaajiyo waxqabadka nidaamka oo loo yareeyo daxalka.Hadda waxa jira tignoolajiyada microchannel oo loo isticmaali karo uumi-baxayaasha iyo kondensayaasha labadaba.
"Tiknooloojiyada microchannel, ee loo yaqaan teknoolojiyadda VERTEX ee Carrier, way ka duwan tahay in tuubooyinka aluminiumka wareega ah lagu beddelo tubbooyin siman oo siman oo lagu iibiyo baalal aluminium," ayuu yidhi Lampe."Tani waxay qaboojiyaha si siman ugu qaybisaa aag ballaaran, waxayna hagaajinaysaa kulaylka si ay gariiradu u shaqeyso si hufan.Halka tignoolajiyada microchannel loo isticmaalay kondensers banaanka la deggan yahay, tignoolajiyada VERTEX waxa hadda loo isticmaalaa oo keliya gariiradaha deegaanka.
Sida laga soo xigtay Jeff Preston, agaasimaha adeegyada farsamada ee Johnson Controls, naqshadeynta microchannel waxay abuurtaa qulqulka qaboojiyaha hal kanaal la fududeeyay oo ka kooban tuubo kulul oo xagga sare ah iyo tuubo qaboojisay xagga hoose.Taas bedelkeeda, qaboojiyaha ku jira gariiradda tuubada fined ee caadiga ah waxay ku socotaa kanaalo badan kor ilaa hoos oo ah qaab mas, oo u baahan dhul badan oo dusha sare ah.
"Naqshadaynta gariiradda microchannel ee gaarka ah waxay bixisaa isku-xidhka wareejinta kulaylka heersare ah, taas oo kordhisa waxtarka waxayna yaraynaysaa qaddarka qaboojiyaha loo baahan yahay," ayuu yidhi Preston."Natiijo ahaan, aaladaha loogu talagalay gariiradaha mikrochannel waxay inta badan aad uga yar yihiin aaladaha waxtarka sare leh ee leh nashqadaha dhaqameed ee fined.Tani waxay ku habboon tahay codsiyada meelaha bannaan sida guryaha leh khadadka eber."
Dhab ahaantii, iyada oo ay ugu wacan tahay soo bandhigida tignoolajiyada microchannel, ayuu yidhi Lampe, Carrier waxa uu awooday in uu hayo inta badan gariiradaha foornada gudaha iyo qaboojiyaha bannaanka ee cabbirka isku midka ah isaga oo la shaqeynaya fin wareega iyo naqshadeynta tuubada.
"Haddii aanaan hirgelin lahayn tignoolajiyadan, waxaan ku qasbanaan lahayn inaan kordhino cabbirka gariiradda foornada gudaha ilaa 11 inji oo sare waxaanan u adeegsan lahayn kondhiyaha dibadda," ayuu yidhi.
In kasta oo tignoolajiyada gariiradda microchannel ugu horrayn loo isticmaalo qaboojiyaha gudaha, fikraddu waxay bilaabmaysaa inay ku qabsato qalabyada ganacsiga maaddaama baahida loo qabo fudud, qalab badan oo is haysta ayaa sii kordhaya, ayuu yidhi Preston.
Sababtoo ah gariiradaha microchannel-ka waxaa ku jira xaddi yar oo qaboojiye ah, xitaa dhowr wiqiyadood oo isbeddel ah ayaa saameyn kara nolosha nidaamka, waxqabadka iyo waxtarka tamarta, Preston ayaa leh.Tani waa sababta ay qandaraaslayaashu had iyo jeer uga hubiyaan soo saaraha habka lacag-bixinta, laakiin badanaa waxay ku lug leedahay tallaabooyinka soo socda:
Sida laga soo xigtay Lampe, tignoolajiyada Carrier VERTEX waxay taageertaa isla habaynta, dallacaadda iyo bilawga habka tignoolajiyada wareega wareega mana u baahna tillaabooyin dheeri ah ama ka duwan habka hadda lagu taliyay ee qaboojinta.
"Qiyaastii 80 ilaa 85 boqolkiiba kharashka ayaa ku jira xaalad dareere ah, markaa qaabka qaboojinta mugga ayaa ku jira xirmada kondenserka dibadda iyo xirmada khadka," Lampe ayaa yidhi."Markaad u guurto gariiradda microchannel oo leh hoos u dhac gudaha ah (marka la barbar dhigo naqshadaha fin ee tuubada wareegsan), farqiga u dhexeeya mas'uuliyadda wuxuu saameeyaa kaliya 15-20% wadarta kharashka, taas oo macnaheedu yahay qayb yar, oo adag in la cabbiro farqiga.Taasi waa sababta habka lagu taliyey ee lagu dallaci karo nidaamka ay tahay iyadoo hoos loo qaboojinayo, oo lagu faahfaahiyay tilmaamahayaga rakibidda.
Si kastaba ha ahaatee, qadarka yar ee qaboojiyaha ku jira gariiradaha microchannel waxay noqon kartaa dhibaato marka bamka kulaylka unugga dibadda uu u wareego habka kuleylka, ayuu yiri Lampe.Habkan, gariiradda nidaamka waa la dami doonaa iyo capacitor-ka kaydiya inta badan kharashka dareeraha hadda waa gariiradda gudaha.
"Marka mugga gudaha ee gariiradda gudaha uu aad uga yar yahay kan gariiradda dibadda, dheelitir la'aanta kharashka ayaa ku dhici karta nidaamka," ayuu yiri Lampe."Si loo xalliyo qaar ka mid ah dhibaatooyinkan, Carrier wuxuu isticmaalaa batari ku dhex jira oo ku yaala unugga dibadda si uu u daadiyo oo uu u kaydiyo kharashka dheeraadka ah ee habka kuleylka.Tani waxay u ogolaaneysaa nidaamka inuu ilaaliyo cadaadiska saxda ah wuxuuna ka hortagayaa kombareeyaha inuu daadiyo, taas oo keeni karta waxqabad xumo maadaama saliiddu ay ku urursan karto gudaha gudaha."
Marka lagu dallaco nidaamka gariiradaha microchannel-ka waxay u baahan kartaa fiiro gaar ah oo faahfaahsan, ku dallaca nidaam kasta oo HVAC ah waxay u baahan tahay si sax ah iyadoo la isticmaalayo qadarka qaboojiyaha saxda ah, ayuu yidhi Lampe.
"Haddii nidaamka uu culeys badan yahay, waxay u horseedi kartaa isticmaalka koronto badan, qaboojin aan fiicnayn, daadinta iyo kombaresarada dhicis ah," ayuu yidhi."Si la mid ah, haddii nidaamka la dallaci karo, qaboojinta gariiradda, gariirada balaarinta, dhibaatooyinka bilawga kombaresarada iyo xiritaanka beenta ah ayaa dhici kara.Dhibaatooyinka gariiradaha microchannel maaha mid ka reeban. "
Sida laga soo xigtay Jeff Preston, agaasimaha adeegyada farsamada ee Johnson Controls, hagaajinta gariiradaha microchannel waxay noqon kartaa mid adag sababtoo ah naqshadooda gaarka ah.
"Alxanka dusha sare wuxuu u baahan yahay qoryo gaas ah oo aan caadi ahayn oo aan loo isticmaalin noocyada kale ee qalabka.Sidaa darteed, qandaraasleyaal badan ayaa dooran doona inay beddelaan gariiradaha halkii ay isku dayi lahaayeen dayactir.
Marka ay timaado in la nadiifiyo gariiradda microchannel, dhab ahaantii way fududahay, ayuu yidhi Mark Lampe, maamulaha alaabta foornada ee Carrier HVAC, sababtoo ah baalasha aluminium ee gariiradaha finned ee tuubada finned ayaa si fudud u foorarsada.Fiinno badan oo qaloocsan ayaa yarayn doona xadiga hawada mara gariiradda, hoos u dhigida waxtarka.
"Tiknooloojiyada sidayaal VERTEX waa naqshad aad u adag sababtoo ah aluminiumka aluminiumku waxay fadhiyaan wax yar ka hooseeya tuubooyinka qaboojiyaha aluminiumka ah waxayna ku dheggan yihiin tuubooyinka, taasoo la micno ah in cadayashadu aanay si weyn u beddelin baalasha," Lampe ayaa yidhi.
Nadiifinta Fudud: Markaad nadiifinayso gariiradaha microchannel-ka, isticmaal kaliya nadiifiyeyaasha gariiradda yaryar ee aan acidic ahayn ama, marar badan, biyo kaliya.(waxaa bixiyay qaaduhu)
Marka aad nadiifinayso gariiradaha microchannel-ka, Preston waxa ay leedahay ka fogow kiimikooyinka adag iyo dhaqista cadaadiska, bedelkeedana isticmaal kaliya nadiifiyeyaasha gariiradda yaryar ee aan acidic ahayn ama, marar badan, biyo kaliya.
"Si kastaba ha ahaatee, qadar yar oo qaboojiye ah ayaa u baahan waxoogaa hagaajin ah habka dayactirka," ayuu yidhi."Tusaale ahaan, cabbirka yar awgeed, qaboojiyaha lama soo saari karo marka qaybaha kale ee nidaamka ay u baahan yihiin adeeg.Intaa waxa dheer, qaybta qalabka waa in lagu xidhaa oo kaliya marka loo baahdo si loo yareeyo carqaladaynta mugga qaboojiyaha. "
Preston waxa uu intaa ku daray in Johnson Controls ay ku dabaqayso xaalado aad u daran dhulkeeda caddaynta ee Florida, taas oo kicisay horumarinta microchannels.
"Natiijooyinka imtixaannadani waxay noo ogolaanayaan inaan horumarino horumarinta alaabtayada annaga oo hagaajineyno dhowr Alloys, dhumucdooda tuubooyinka iyo kimistaha la wanaajiyey ee habka xajinta jawiga la xakameeyey si loo xaddido daxalka gariiradda iyo hubinta heerarka ugu wanaagsan ee waxqabadka iyo kalsoonida la gaaro," ayuu yidhi."Qoritaanka tillaabooyinkan kaliya ma kordhinayaan ku qanacsanaanta mulkiilaha guriga, laakiin waxay sidoo kale gacan ka geysan doontaa dhimista baahiyaha dayactirka."
