2. Umbutho wokuhamba komoya
Umbutho wokuhamba komoya wegumbi elicocekileyo uhluke kuleyo yegumbi elinomoya opholileyo. Ifuna ukuba umoya ococekileyo uhanjiswe kwindawo yokusebenza kuqala. Umsebenzi wayo kukukhawulela kunye nokunciphisa ungcoliseko kwizinto ezicutshungulwayo. Kule njongo, le migaqo ilandelayo kufuneka iqwalaselwe xa kuyilwa umbutho wokuhamba komoya: ukunciphisa i-eddy currents ukuphepha ukuzisa ukungcola ngaphandle kwendawo yokusebenza kwindawo yokusebenza; zama ukuthintela ukubhabha kothuli lwesibini ukunciphisa ithuba lokungcolisa uthuli umsebenzi; ukuhamba komoya kwindawo yokusebenzela kufuneka kufane ngokusemandleni, kwaye isantya sayo somoya kufuneka sihlangabezane nenkqubo kunye neemfuno zococeko. Xa umoya uqukuqela ukuya kwindawo yokuphuma komoya, uthuli olusemoyeni kufuneka lususwe ngokufanelekileyo. Khetha iindlela ezahlukeneyo zokuhanjiswa komoya kunye nokubuyisela ngokweemfuno ezahlukeneyo zokucoceka.
Imibutho eyahlukeneyo yomoya ineempawu zayo kunye nemida:
(1). Ukuqukuqela okuthe nkqo unidirectional
Ukongeza kwiinzuzo eziqhelekileyo zokufumana ukuhamba komoya okufanayo okuya ezantsi, ukuququzelela ulungelelwaniso lwezixhobo zenkqubo, amandla okuzisulungekisa, kunye nokwenza lula izibonelelo eziqhelekileyo ezinje ngezixhobo zokuzicoca, iindlela ezine zokubonelela komoya nazo zineengenelo zazo kunye nezingeloncedo zazo: izihluzi zehepa ezigqunywe ngokupheleleyo zineengenelo zokuxhathisa okuphantsi kunye nomjikelo omde wokutshintsha isihluzi, kodwa ulwakhiwo lwesilingi luphezulu; izinto eziluncedo kunye nezingeloncedo ezigqunywe ngecala lonikezelo lokucoca ihepa kunye nepleyiti egcwele umngxuma unikezelo lwaphezulu luchasene nezo zehepa ezigqunywe ngokupheleleyo. Phakathi kwabo, ukuhanjiswa okuphezulu kweplate egcweleyo kulula ukuqokelela uthuli kwindawo yangaphakathi yeplate ye-orifice xa inkqubo ingasebenzi ngokuqhubekayo, kwaye ukugcinwa kakubi kunempembelelo ethile ekucocekeni; i-dense diffuser top delivery ifuna umxube wokuxuba, ngoko ke ifanelekile kuphela kumagumbi amade acocekileyo ngaphezu kwe-4m, kwaye iimpawu zayo zifana nokuhanjiswa kweplate egcweleyo; indlela yokubuyisela i-air plate kunye ne-grilles kumacala omabini kunye neendawo zokubuya zomoya ezilungelelanisiweyo zilungelelaniswe phantsi kweendonga ezichaseneyo zifanelekile kuphela kumagumbi ahlambulukileyo kunye nesithuba somnatha esingaphantsi kwe-6m kumacala omabini; iindawo zokubuyiswa zomoya ezilungiselelwe phantsi kodonga olulodwa zifanelekile kuphela kumagumbi acocekileyo kunye nomgama omncinci phakathi kweendonga (ezifana ≤<2 ~ 3m).
(2). Ukuqukuqela okuthe tye kwe-unidirectional
Kuphela indawo yokuqala yokusebenza inokufikelela kwinqanaba lokucoceka kwe-100. Xa umoya ugeleza kwelinye icala, ugxininiso lothuli lukhula ngokuthe ngcembe. Ngoko ke, ifanelekile kuphela kumagumbi acocekileyo aneemfuno ezahlukeneyo zokucoceka kwinkqubo efanayo kwigumbi elinye. Ukusasazwa kwendawo yokucoca i-hepa eludongeni lokubonelela ngomoya kunokunciphisa ukusetyenziswa kweefilitha ze-hepa kunye nokugcina utyalo-mali lokuqala, kodwa kukho i-eddies kwiindawo zendawo.
(3). Ukuqukuqela komoya
Iimpawu zokuhanjiswa okuphezulu kweeplate ze-orifice kunye nokuhanjiswa okuphezulu kwee-diffusers ezixineneyo ziyafana nezi zikhankanywe ngasentla: iingenelo zokuhanjiswa kwecala kulula ukucwangcisa imibhobho, akukho interlayer yobugcisa efunekayo, ixabiso eliphantsi, kwaye lilungele ukulungiswa kweefektri ezindala. Ukungalungi kukuba isantya somoya kwindawo yokusebenza sikhulu, kwaye i-concentration yothuli kwicala le-downwind liphezulu kunelo liphezulu; ukuhanjiswa okuphezulu kwezixhobo zokucoca i-hepa kunezibonelelo zenkqubo elula, akukho mibhobho emva kwesihluzo se-hepa, kunye nokuhamba komoya okucocekileyo kuhanjiswe ngokuthe ngqo kwindawo yokusebenza, kodwa ukuhamba komoya ococekileyo kusasazeka kancinci kwaye ukuhamba komoya kwindawo yokusebenza kufana ngakumbi; nangona kunjalo, xa ii-air outlets ezininzi zilungelelaniswa ngokulinganayo okanye i-hepa filter air outlets ezine-diffusers zisetyenziswa, ukuhamba komoya kwindawo yokusebenza kunokwenziwa okufanayo ngakumbi; kodwa xa isixokelelwano singasebenzi ngokuqhubekayo, i-diffuser ithanda ukuqokelelana uthuli.
Le ngxoxo ingentla ikwimeko efanelekileyo kwaye ikhuthazwa yimigaqo yesizwe efanelekileyo, imigangatho okanye iincwadana zoyilo. Kwiiprojekthi zokwenyani, umbutho wokuhamba komoya awulungiswanga kakuhle ngenxa yeemeko zenjongo okanye izizathu ezizimeleyo zomyili. Eziqhelekileyo zibandakanya: ukuhamba okuthe nkqo kwe-unidirectional kwamkela ukubuya komoya ukusuka kwindawo engezantsi yeendonga ezimbini ezikufutshane, iklasi ye-100 yendawo ithatha ukuhanjiswa okuphezulu kunye nembuyekezo ephezulu (oko kukuthi, akukho mkhusane oxhonyiweyo wongezwa phantsi kwendawo yokuphuma yomoya), kunye namagumbi ahlambulukileyo ahlambulukileyo amkela i-hepa filter air outlet top kunye nokubuya okuphezulu okanye i-single-side-side-side ne-side-side measurement returning ( etc. iimfuno zoyilo. Ngenxa yemigqaliselo yangoku yokwamkelwa okungenanto okanye okuzinzileyo, amanye ala magumbi acocekileyo afikelela kwinqanaba lokucoceka eliyilwe kwiimeko ezingenanto okanye ezizinzileyo, kodwa amandla okuphazamisa ukungcola aphantsi kakhulu, kwaye emva kokuba igumbi elicocekileyo lingena kwimeko yokusebenza, ayihambelani neemfuno.
Umbutho ochanekileyo wokuhamba komoya kufuneka umiselwe kunye namakhethini axhomekeke ekuphakameni kwendawo yokusebenza kwindawo yendawo, kwaye iklasi ye-100,000 akufanele ithathe ukuhanjiswa okuphezulu kunye nokubuya okuphezulu. Ukongeza, uninzi lweefektri okwangoku zivelisa izixhobo zomoya eziphezulu ezinezixhobo zokusasaza, kwaye ii-diffusers zazo ziipleyiti zokuhombisa kuphela kwaye azidlali indima yokusasaza ukuhamba komoya. Abaqulunqi kunye nabasebenzisi kufuneka banikele ingqalelo ekhethekileyo kule nto.
3. Umthamo wokunikezelwa komoya okanye isantya somoya
Umthamo owaneleyo wokungena komoya kukungxenga nokususa umoya ongcolisekileyo wangaphakathi. Ngokweemfuno ezahlukeneyo zokucoceka, xa ubude bomnatha begumbi elicocekileyo buphezulu, i-frequency yokungenisa umoya kufuneka yandiswe ngokufanelekileyo. Phakathi kwabo, umthamo we-ventilation we-1 ye-million-level room ecocekileyo ithathwa ngokwenkqubo yokucoca ngokufanelekileyo, kwaye abanye baqwalaselwa ngokwenkqubo yokucoca ephezulu; xa izihluzi ze-hepa zeklasi ze-100,000 zegumbi elicocekileyo zigxininiswe kwigumbi lomatshini okanye izihlungi ze-sub-hepa zisetyenziswe ekupheleni kwenkqubo, i-ventilation frequency inokunyuswa ngokufanelekileyo nge-10-20%.
Ngomthamo wokungena umoya ongentla amaxabiso anconyiweyo, umbhali ukholelwa ukuba: isantya somoya ngokusebenzisa icandelo legumbi le-unidirectional flow flow clean room liphantsi, kwaye igumbi elinesiphithiphithi elicocekileyo linexabiso elicetyiswayo elinento eyaneleyo yokhuseleko. I-Vertical unidirectional flow ≥ 0.25m / s, i-horizontal unidirectional flow ≥ 0.35m / s. Nangona iimfuno zococeko zinokufezekiswa xa zivavanywa kwiimeko ezingenanto okanye ezizinzileyo, amandla okuchasana nongcoliseko abi. Emva kokuba igumbi lingena kwindawo yokusebenza, ukucoceka akunakuhlangabezana neemfuno. Olu hlobo lomzekelo aluyonto yodwa. Kwangaxeshanye, akukho balandeli balungele iinkqubo zokucoca kuthotho lwelizwe lam lokungenisa umoya. Ngokuqhelekileyo, abaqulunqi bahlala bengenzi izibalo ezichanekileyo zokumelana nomoya wenkqubo, okanye abaqapheli ukuba i-fan ekhethiweyo ikwindawo yokusebenza ethandeka ngakumbi kwi-curve yeempawu, okubangela ukuba umthamo womoya okanye isantya somoya usilele ukufikelela kwixabiso loyilo ngokukhawuleza emva kokuba inkqubo ifakwe ekusebenzeni. Umgangatho we-federal yase-US (FS209A ~ B) ichaze ukuba isantya sokuhamba komoya segumbi elicocekileyo eli-unidirectional ngokusebenzisa indawo enqamlezileyo yegumbi elicocekileyo lihlala ligcinwa kwi-90ft / min (0.45m / s), kwaye isantya esingafaniyo singaphakathi kwe-± 20% phantsi komqathango wokungabikho kokuphazamiseka kwigumbi lonke. Nakuphi na ukuhla okubalulekileyo kwisantya sokuhamba komoya kuya kwandisa ithuba lokuzicoca kunye nongcoliseko phakathi kwezikhundla zokusebenza (emva kokubhengezwa kweFS209C ngo-Oktobha 1987, akukho migaqo yenziwayo kuzo zonke izibonakaliso zeparameter ngaphandle koxinzelelo lothuli).
Ngenxa yesi sizathu, umbhali ukholelwa ukuba kufanelekile ukunyusa ngokufanelekileyo ixabiso loyilo lwasekhaya lwangoku lwe-unidirectional flow velocity. Iyunithi yethu ikwenzile oku kwiiprojekthi zokwenyani, kwaye umphumo ulungile. Igumbi lokucoceka elinesiphithiphithi linexabiso elicetyiswayo elinento yokhuseleko eyaneleyo, kodwa abaqulunqi abaninzi abakaqinisekiswa. Xa usenza iiplani ezithile, zandisa umthamo we-ventilation yeklasi ye-100,000 igumbi elicocekileyo ukuya kumaxesha angama-20-25 / h, iklasi ye-10,000 igumbi elicocekileyo ukuya kumaxesha angama-30-40 / h, kunye neklasi ye-1000 igumbi elicocekileyo ukuya kuma-60-70 amaxesha / h. Oku akugcini nje ukwandisa umthamo wezixhobo kunye notyalo-mali lokuqala, kodwa kwandisa iindleko zokugcina kunye nolawulo lwexesha elizayo. Enyanisweni, akukho mfuneko yokwenjenjalo. Xa uqulunqa amanyathelo obugcisa bokucoca umoya welizwe lam, ngaphezu kweklasi ye-100 igumbi elicocekileyo e-China laphandwa kwaye lalinganiswa. Amagumbi amaninzi acocekileyo avavanywa phantsi kweemeko eziguquguqukayo. Iziphumo zibonise ukuba umthamo we-ventilation weklasi 100,000 amagumbi acocekileyo ≥10 amaxesha / h, iklasi 10,000 amagumbi acocekileyo ≥20 amaxesha / h, kunye neklasi 1000 amagumbi acocekileyo ≥50 amaxesha / h unokuhlangabezana neemfuno. I-US Federal Standard (FS2O9A ~ B) ichaza: amagumbi acocekileyo angenawo unidirectional (iklasi 100,000, iklasi 10,000), ukuphakama kwegumbi 8 ~ 12ft (2.44 ~ 3.66m), ngokuqhelekileyo kuthathelwe ingqalelo igumbi lonke ukuba lingene umoya ubuncinane kanye kwimizuzu emi-3 (okt amaxesha angama-20 / h). Ngoko ke, inkcazo yoyilo ithathele ingqalelo i-coefficient enkulu ye-surplus, kwaye umyili unokukhetha ngokukhuselekileyo ngokwexabiso elicetyiswayo lomthamo wokungena umoya.
4. Umahluko woxinzelelo olusisigxina
Ukugcina uxinzelelo oluthile olulungileyo kwigumbi elicocekileyo yenye yeemeko eziyimfuneko zokuqinisekisa ukuba igumbi elicocekileyo alikho okanye lingcolisekile ngaphantsi ukuze kugcinwe umgangatho wococeko owenziweyo. Kwanamagumbi acocekileyo oxinzelelo olubi, kufuneka abe namagumbi akufutshane okanye ii-suites ezinomgangatho wokucoceka ongekho ngaphantsi kwinqanaba lawo ukugcina uxinzelelo oluthile olulungileyo, ukwenzela ukuba ukucoceka koxinzelelo olubi olucocekileyo lunokugcinwa.
Ixabiso elihle loxinzelelo lwegumbi elicocekileyo libhekiselele kwixabiso xa uxinzelelo lwe-static lwangaphakathi lukhulu kunoxinzelelo lwangaphandle lwe-static xa zonke iingcango kunye neefestile zivaliwe. Iphunyezwa ngendlela yokuba umthamo wokunikezelwa komoya wenkqubo yokucoca mkhulu kunomthamo womoya wokubuya kunye nokukhupha umthamo womoya. Ukuze kuqinisekiswe ixabiso elifanelekileyo loxinzelelo lwegumbi elicocekileyo, ukubonelela, ukubuyisela kunye nokukhupha abalandeli ngokufanelekileyo badibeneyo. Xa inkqubo ivuliwe, umqhubi wokubonelela uqalwa kuqala, kwaye emva koko abalandeli bokubuyisela kunye nokukhupha baqalwa; xa inkqubo icinyiwe, i-fan exhaust ivaliwe kuqala, kwaye emva koko abalandeli bokubuyisela kunye nokubonelela bayacinywa ukukhusela igumbi elicocekileyo ukuba lingangcoliswa xa inkqubo ivuliwe kwaye ivaliwe.
Umthamo womoya ofunekayo ukuze kugcinwe uxinzelelo olulungileyo lwegumbi elicocekileyo lichongwa ngokuyinhloko kumoya womoya wesakhiwo sokugcina. Kwiintsuku zokuqala zokwakhiwa kwegumbi elicocekileyo kwilizwe lam, ngenxa yokungangeni komoya okungahambi kakuhle kwesakhiwo esivaliweyo, kwathatha amaxesha ama-2 ukuya kuma-6 / h wokunikezelwa komoya ukugcina uxinzelelo oluhle lwe-≥5Pa; okwangoku, umoya womoya wesakhiwo sokugcinwa uphuculwe kakhulu, kwaye kuphela i-1 ukuya kwi-2 amaxesha / iyure yokunikezelwa komoya ifunekayo ukuze kugcinwe uxinzelelo olufanayo; kwaye kuphela i-2 ukuya kwi-3 amaxesha / iyure yokunikezelwa komoya efunekayo ukugcina i-≥10Pa.
iinkcukacha zoyilo lwelizwe lam [6] ichaza ukuba umahluko uxinzelelo static phakathi kwamagumbi acocekileyo amabakala ahlukeneyo naphakathi kweendawo ezicocekileyo kunye neendawo ezingacocekanga kufuneka hayi ngaphantsi kwe-0.5mm H2O (~5Pa), kunye noxinzelelo lwe-static umahluko phakathi kwendawo ecocekileyo nangaphandle kufuneka ingabi ngaphantsi kwe-1.0mm H2O (~10Pa). Umbhali ukholelwa ukuba eli xabiso libonakala liphantsi kakhulu ngenxa yezizathu ezithathu:
(1) Uxinzelelo olulungileyo lubhekiselele ekukwazini kwegumbi elicocekileyo ukucinezela ungcoliseko lomoya wangaphakathi ngokusebenzisa izikhewu phakathi kweengcango kunye neefestile, okanye ukunciphisa ungcoliseko olungena kwigumbi xa iingcango neefestile zivulwe ixesha elifutshane. Ubungakanani boxinzelelo olulungileyo bubonisa amandla okukwazi ukucinezela ungcoliseko. Ngokuqinisekileyo, ubukhulu bexinzelelo olulungileyo, lungcono (oluya kuxutyushwa kamva).
(2) Umthamo womoya ofunekayo kuxinzelelo oluhle ulinganiselwe. Umthamo womoya ofunekayo kwi-5Pa yoxinzelelo oluhle kunye ne-10Pa yoxinzelelo oluhle kuphela malunga ne-1 ixesha / h eyahlukileyo. Kutheni ungayenzi? Ngokucacileyo, kungcono ukuthatha umda osezantsi woxinzelelo olulungileyo njenge-10Pa.
(3) I-US Federal Standard (FS209A~B) ichaza ukuba xa zonke iindlela zokungena kunye nokuphuma zivaliwe, umahluko omncinci woxinzelelo olulungileyo phakathi kwegumbi elicocekileyo kunye nayo nayiphi na indawo ephantsi yokucoceka ekufutshane yi-0.05 intshi yekholomu yamanzi (12.5Pa). Eli xabiso liye lamkelwa ngamazwe amaninzi. Kodwa ixabiso loxinzelelo olulungileyo lwegumbi elicocekileyo alikho phezulu. Ngokweemvavanyo zangempela zobunjineli zeyunithi yethu iminyaka engaphezu kwe-30, xa ixabiso loxinzelelo oluhle ≥ 30Pa, kunzima ukuvula umnyango. Ukuba uvala ucango ngokungakhathali, kuya kwenza isithonga! Iza koyikisa abantu. Xa ixabiso loxinzelelo oluhle ≥ 50 ~ 70Pa, izikhewu phakathi kweengcango kunye neefestile ziya kwenza ikhwelo, kwaye ababuthathaka okanye abaneempawu ezingafanelekanga baya kuziva bengakhululekile. Nangona kunjalo, iinkcukacha ezifanelekileyo okanye imigangatho yamazwe amaninzi ekhaya nakwamanye amazwe ayicacisi umda ophezulu woxinzelelo olulungileyo. Ngenxa yoko, iiyunithi ezininzi zifuna kuphela ukuhlangabezana neemfuno zomda ophantsi, kungakhathaliseki ukuba ungakanani umda ophezulu. Kwigumbi langempela elicocekileyo elidibana nombhali, ixabiso lexinzelelo elihle liphezulu njenge-100Pa okanye ngaphezulu, okubangelwa yimiphumo emibi kakhulu. Enyanisweni, ukulungelelanisa uxinzelelo olulungileyo akuyona into enzima. Kunokwenzeka ngokupheleleyo ukuyilawula ngaphakathi koluhlu oluthile. Kwakukho uxwebhu oluzisa ukuba ilizwe elithile eMpuma Yurophu lichaza ixabiso lexinzelelo elihle njenge-1-3mm H20 (malunga ne-10 ~ 30Pa). Umbhali ukholelwa ukuba olu luhlu lufanelekile ngakumbi.
