Sekondale Return Air scheme Kwa Air Conditioning System

Malo ochezera ang'onoang'ono amagetsi okhala ndi chipinda chaching'ono choyera komanso utali wocheperako wolowera mpweya womwe umagwiritsidwa ntchito kutengera njira yachiwiri yobwereranso ya air conditioning system. Chiwembu ichi chimagwiritsidwanso ntchito kwambirizipinda zoyeram'mafakitale ena monga azachipatala ndi azachipatala. Chifukwa voliyumu yolowera mpweya kuti ikwaniritse zofunikira za chinyezi choyera m'chipindacho nthawi zambiri imakhala yocheperako kuposa kuchuluka kwa mpweya wofunikira kuti ufike paukhondo, motero kusiyana kwa kutentha pakati pa mpweya woperekera ndi mpweya wobwerera kumakhala kochepa. Ngati chiwongolero choyambirira cha mpweya chikugwiritsidwa ntchito, kusiyana kwa kutentha pakati pa malo operekera mpweya wa mpweya ndi mame a mpweya wa mpweya ndi waukulu, kutentha kwachiwiri kumafunika, zomwe zimapangitsa kuti kutentha kuzizira kuthetsedwe mu ndondomeko ya chithandizo cha mpweya komanso kugwiritsa ntchito mphamvu zambiri. Ngati ndondomeko yachiwiri yobwereranso ikugwiritsidwa ntchito, mpweya wobwereranso wachiwiri ungagwiritsidwe ntchito m'malo mwa kutentha kwachiwiri kwa pulayimale yobwerera. Ngakhale kusintha kwa chiŵerengero cha mpweya wobwerera ku pulayimale ndi chachiwiri kumakhala kochepa kwambiri kusiyana ndi kusintha kwa kutentha kwachiwiri, ndondomeko yachiwiri yobwereranso yakhala ikudziwika kwambiri ngati njira yopulumutsira mphamvu yopulumutsa mphamvu m'magulu ang'onoang'ono ndi apakatikati a micro-electronic clean workshops.

Tengani chitsanzo cha ISO class 6 microelectronics clean workshop mwachitsanzo, malo ochitira misonkhano oyera a 1 000 m2, kutalika kwa denga ndi 3 m. Mkati mapangidwe magawo ndi kutentha tn = (23 ± 1) ℃, chinyezi wachibale φn = 50% ± 5%; The kamangidwe mpweya kotunga voliyumu ndi 171,000 m3/h, za 57 h-1 mpweya kuwombola nthawi, ndi mpweya wabwino voliyumu ndi 25 500 m3/h (amene ndondomeko utsi mpweya voliyumu ndi 21 000 m3 / h, ndi zina ndi zabwino kuthamanga kutayikira mpweya voliyumu). Kutentha kwanzeru mu msonkhano woyera ndi 258 kW (258 W / m2), chiŵerengero cha kutentha / chinyezi cha mpweya wozizira ndi ε = 35 000 kJ / kg, ndipo kusiyana kwa kutentha kwa mpweya wobwerera m'chipindamo ndi 4.5 ℃. Panthawi imeneyi, chachikulu kubwerera mpweya buku la
Iyi ndiyo njira yomwe imagwiritsidwa ntchito kwambiri yoyeretsera mpweya mu chipinda choyera cha makampani a microelectronics, dongosolo lamtunduwu likhoza kugawidwa makamaka mu mitundu itatu: AHU + FFU; MAU+AHU+FFU; MAU+DC (Dry coil) +FFU. Aliyense ali ndi ubwino wake ndi kuipa ndi malo oyenera, mphamvu yopulumutsa mphamvu makamaka zimadalira ntchito fyuluta ndi zimakupiza ndi zipangizo zina.

1) AHU + FFU dongosolo.

Mtundu wamtunduwu umagwiritsidwa ntchito mumakampani opanga ma microelectronics ngati "njira yolekanitsa mpweya ndi gawo loyeretsa". Pakhoza kukhala zinthu ziwiri: imodzi ndi yakuti mpweya wabwino umangogwira ntchito ndi mpweya wabwino, ndipo mpweya wabwino umanyamula katundu wonse wa kutentha ndi chinyezi cha chipinda choyera ndipo umakhala ngati mpweya wowonjezera kuti ugwirizane ndi mpweya wotulutsa mpweya komanso kuthamanga kwabwino kwa chipinda choyera, dongosololi limatchedwanso MAU + FFU dongosolo; The ena ndi kuti mpweya wabwino voliyumu yekha sikokwanira kukumana ozizira ndi kutentha katundu zofunika chipinda choyera, kapena chifukwa mpweya wabwino ndi kukonzedwa kuchokera kunja kunja kwa mame enieni enthalpy kusiyana kwa makina chofunika ndi lalikulu kwambiri, ndi mbali ya mpweya m'nyumba (lofanana ndi mpweya wobwerera) amabwerera ku unit air conditioning treatment, wosakanikirana ndi mpweya watsopano kutentha ndi chinyezi, kutumizidwa ku chithandizo cha mpweya. Kusakanikirana ndi mpweya wotsalira wa chipinda choyera (chofanana ndi mpweya wobwereza wachiwiri), umalowa mu FFU unit ndikutumiza ku chipinda choyera. Kuyambira 1992 mpaka 1994, wolemba wachiwiri wa pepalali adagwirizana ndi kampani yaku Singapore ndipo adatsogolera ophunzira opitilira 10 kuti atenge nawo gawo pakupanga mgwirizano wa US-Hong Kong SAE Electronics Factory, yomwe idatengera mtundu womaliza wa zowongolera mpweya ndi mpweya wabwino. Ntchitoyi ili ndi chipinda choyera cha ISO Class 5 pafupifupi 6,000 m2 (1,500 m2 yomwe idapangidwa ndi Japan Atmospheric Agency). Chipinda choyatsira mpweya chimakonzedwa mofanana ndi mbali ya chipinda choyera pambali pa khoma lakunja, ndipo kokha moyandikana ndi korido. Mpweya wabwino, mpweya wotulutsa mpweya ndi mapaipi obwerera mpweya ndiafupi komanso amakonzedwa bwino.

2) MAU+AHU+FFU scheme.

Njira yothetsera vutoli imapezeka kawirikawiri muzomera za microelectronics zomwe zimakhala ndi zofunikira zambiri za kutentha ndi chinyezi komanso kusiyana kwakukulu kwa kutentha ndi kutentha kwa chinyezi, komanso mulingo waukhondo ndi wapamwamba. M'nyengo yotentha, mpweya wabwino umakhazikika ndipo umasungunuka mpaka pamalo okhazikika. Nthawi zambiri zimakhala zoyenera kuchiza mpweya wabwino mpaka pa mphambano ya mzere wa isometric enthalpy ndi mzere wa chinyezi wa 95% wa chipinda choyera ndi kutentha koyimilira ndi chinyezi kapena chipinda choyera chokhala ndi mpweya wabwino kwambiri. Kuchuluka kwa mpweya wa MAU kumatsimikiziridwa molingana ndi zosowa za chipinda chilichonse choyera kuti chiwonjezere mpweya, ndikugawidwa kwa AHU m'chipinda chilichonse choyera ndi mapaipi malinga ndi mpweya wabwino wa mpweya wabwino, ndipo umasakanizidwa ndi mpweya wina wobwerera m'nyumba pofuna kutentha ndi chinyezi. Chigawochi chimanyamula kutentha ndi chinyezi chonse ndi gawo la rheumatism yatsopano ya chipinda choyera chomwe chimatumikira. Mpweya wopangidwa ndi AHU aliyense umatumizidwa ku mpweya wokwanira m'chipinda chilichonse choyera, ndipo pambuyo pa kusakanikirana kwachiwiri ndi mpweya wobwerera m'nyumba, umatumizidwa m'chipindamo ndi FFU unit.

Ubwino waukulu wa njira yothetsera MAU + AHU + FFU ndikuti kuwonjezera pa kuonetsetsa kuti ukhondo ndi kupanikizika kwabwino, zimatsimikiziranso kutentha kosiyana ndi chinyezi chofunikira kuti pakhale ndondomeko yoyera ya chipinda chilichonse. Komabe, nthawi zambiri chifukwa cha chiwerengero cha AHU anakhazikitsa, kulanda chipinda m'dera lalikulu, chipinda choyera mpweya wabwino, kubwerera mpweya, mapaipi mpweya crisscross, atenge malo lalikulu, masanjidwewo ndi ovuta, kukonza ndi kasamalidwe ndi zovuta ndi zovuta, Choncho, palibe zofunika zapadera monga momwe angathere kupewa ntchito.
