Iskimu sokuBuyiselwa koMoya okwesibini kwiNkqubo yokuFakelwa koMoya

Iworkshop ye-elektroniki encinci enendawo encinci yegumbi ecocekileyo kunye neradiyasi enyiniweyo yombhobho womoya wokubuya osetyenziselwa ukwamkela iskimu somoya esibuyiswayo sesibini senkqubo yokupholisa umoya. Esi sikimu sikwasetyenziswa ngokuqhelekileyo kwiamagumbi acocekileyokwamanye amashishini afana namayeza kunye nokhathalelo lwezonyango. Ngenxa yokuba umthamo wokungena komoya wokuphefumla ukuhlangabezana neemfuno zokufuma kobushushu begumbi elicocekileyo ngokuqhelekileyo ungaphantsi kakhulu kunomthamo wokungena komoya ofunekayo ukufikelela kwinqanaba lokucoceka, ngoko ke, umahluko wobushushu phakathi komoya wonikezelo kunye nomoya wokubuya umncinci. Ukuba iskimu somoya esisisiseko sisetyenzisiweyo, umahluko weqondo lobushushu phakathi kwendawo yonikezelo lwemo yomoya kunye nendawo yombethe yeyunithi yokupholisa umoya inkulu, ukufudumeza okwesibini kuyafuneka, okukhokelela ekupheliseni ubushushu obubandayo kwinkqubo yonyango lomoya kunye nokusetyenziswa kwamandla ngakumbi. . Ukuba isicwangciso somoya wesibini sisetyenzisiweyo, umoya wesibini wokubuyisela ungasetyenziselwa ukubuyisela ukufudumeza okwesibini kweskimu somoya sokuqala. Nangona ulungelelwaniso lomlinganiselo womoya osisiseko kunye nowesibini obuyayo ubuthathaka kancinci kunohlengahlengiso lobushushu besibini, iskim somoya esibuyiswayo sesibini siye samkelwa ngokubanzi njengomlinganiselo wokonga amandla omoya kwiindibano zocweyo ezincinci neziphakathi ezicocekileyo ze-elektroniki. .

Thatha i-ISO yeklasi ye-6 microelectronics clean workshop ecocekileyo njengomzekelo, indawo yokusebenzela ecocekileyo ye-1 000 m2, ukuphakama kwesilingi ye-3 m. Iiparamitha zoyilo lwangaphakathi bubushushu tn= (23±1) ℃, ukufuma okunxulumene φn=50%±5%; Umthamo wokunikezelwa komoya woyilo ngu-171,000 m3 / h, malunga ne-57 h-1 amaxesha okutshintshana komoya, kunye nomthamo womoya omtsha ngu-25 500 m3 / h (apho inkqubo yokukhupha umthamo womoya yi-21 000 m3 / h, kwaye enye i- Uxinzelelo oluhle ukuvuza umthamo womoya). Ukushisa okunengqiqo kwi-workshop ecocekileyo yi-258 kW (258 W / m2), umlinganiselo wokushisa / womswakama we-air conditioner ngu-ε = 35 000 kJ / kg, kwaye ukuhluka kweqondo lokushisa kwegumbi lokubuya komoya ngu-4.5 ℃. Ngeli xesha, umthamo womoya wokubuyisela ophambili we
Oku okwangoku kuyindlela esetyenziswa ngokuqhelekileyo yokuhlanjululwa kwenkqubo yokucoca umoya kwimboni ye-microelectronics igumbi elicocekileyo, olu hlobo lwenkqubo lunokwahlulwa ngokukodwa kwiindidi ezintathu: AHU + FFU; MAU+AHU+FFU; MAU+DC (Ikhoyili eyomileyo) +FFU. Ngamnye uneenzuzo kunye nokungonakali kunye neendawo ezifanelekileyo, umphumo wokonga amandla ubukhulu becala kuxhomekeke ekusebenzeni kwesihluzo kunye nefeni kunye nezinye izixhobo.

1) Inkqubo ye-AHU + FFU.

Olu hlobo lwenkqubo yenkqubo lusetyenziswa kwishishini le-microelectronics “njengendlela yokwahlula umoya womoya kunye nesigaba sokucoca”. Kunokubakho iimeko ezimbini: enye yeyokuba inkqubo yokupholisa umoya ijongana nomoya omtsha kuphela, kwaye umoya omtsha ophathwayo uthwala bonke ubushushu kunye nomthwalo wokufuma wegumbi elicocekileyo kwaye usebenze njengowongezelela umoya wokulungelelanisa ukukhupha umoya kunye nokuvuza koxinzelelo oluhle. yegumbi elicocekileyo, le nkqubo ibizwa ngokuba yinkqubo ye-MAU + FFU; Enye kukuba umthamo womoya omtsha wedwa akwanelanga ukuhlangabezana neemfuno zomthwalo obandayo kunye nobushushu begumbi elicocekileyo, okanye ngenxa yokuba umoya omtsha ucutshungulwa ukusuka kwimeko yangaphandle ukuya kwindawo yombethe umahluko othile we-enthalpy yomatshini ofunekayo mkhulu kakhulu. , kunye nenxalenye yomoya wangaphakathi (okulingana nomoya obuyayo) ubuyiselwa kwiyunithi yonyango ye-air conditioning, ixutywe nomoya omtsha wokushisa nokushisa, kwaye emva koko ithunyelwe kwi-plenum yokubonelela ngomoya. Ixutywe negumbi eliseleyo elicocekileyo lokubuyisela umoya (elilingana nomoya wesibini wokubuya), lingena kwiyunithi yeFFU kwaye emva koko iyithumele kwigumbi elicocekileyo. Ukususela ngo-1992 ukuya ku-1994, umbhali wesibini weli phepha usebenzisane nenkampani yaseSingapore kwaye wakhokelela abafundi abangaphezu kwe-10 abaphumeleleyo ukuba bathathe inxaxheba kuyilo lwe-US-Hong Kong i-joint venture ye-SAE Electronics Factory, eyamkela uhlobo lokugqibela lokucoca umoya kunye ne-air conditioning. inkqubo yokungenisa umoya. Le projekthi inegumbi elicocekileyo le-ISO Class 5 elimalunga ne-6,000 m2 (1,500 m2 ekuye kwavunyelwana ngalo yi-Japan Atmospheric Agency). Igumbi lokupholisa umoya licwangciswe ngokuhambelana necala legumbi elicocekileyo ecaleni kodonga lwangaphandle, kwaye kuphela kufuphi ne-corridor. Umoya omtsha, ukukhupha umoya kunye nemibhobho yomoya yokubuyisela imfutshane kwaye ihlelwe kakuhle.

2) MAU + AHU + FFU iskimu.

Esi sisombululo sifumaneka ngokuqhelekileyo kwizityalo ze-microelectronics ezineemfuno ezininzi zokushisa kunye nomswakama kunye nokwahlukana okukhulu kubushushu kunye nomthwalo womswakama, kunye nenqanaba lokucoceka liphezulu. Ehlotyeni, umoya omtsha upholile kwaye uhlanjululwe kwi-fixed parameter point. Ngokuqhelekileyo kuyafaneleka ukunyanga umoya omtsha ukuya kwindawo yokuhlangana yomgca we-isometric enthalpy kunye nomgca we-95% we-humidity yegumbi elicocekileyo kunye nobushushu obumele kunye nomswakama okanye igumbi elicocekileyo elinomthamo omkhulu womoya omtsha. Umthamo womoya we-MAU umiselwe ngokweemfuno zegumbi ngalinye elicocekileyo lokuzalisa umoya, kwaye usasazwe kwi-AHU yegumbi ngalinye elicocekileyo elinemibhobho ngokuhambelana nomthamo womoya ococekileyo ofunekayo, kwaye uxutywe kunye nomoya othile wokubuyisela ngaphakathi ukuze ubushushu. kunye nonyango lokufuma. Le yunithi ithwala bonke ubushushu kunye nomthwalo wokufuma kunye nenxalenye yomthwalo omtsha we-rheumatism wegumbi elicocekileyo elisebenzayo. Umoya ophathwa yi-AHU nganye uthunyelwa kwi-plenum yobonelelo lomoya kwigumbi ngalinye elicocekileyo, kwaye emva kokuxutywa kwesibini kunye nomoya wokubuyisela ngaphakathi, uthunyelwa kwigumbi yiyunithi ye-FFU.

Inzuzo ephambili yesisombululo se-MAU + AHU + FFU kukuba ngaphezu kokuqinisekisa ukucoceka kunye noxinzelelo oluhle, iphinda iqinisekise ukushisa okuhlukeneyo kunye nomswakama ohambelanayo ofunekayo ekuveliseni inkqubo yegumbi elicocekileyo. Nangona kunjalo, ngokufuthi ngenxa yenani le-AHU elisekiweyo, hlala kwindawo yegumbi likhulu, igumbi elicocekileyo lomoya omtsha, umoya wokubuya, imibhobho yonikezelo lomoya, ithatha indawo enkulu, uyilo luyinkathazo ngakumbi, ukugcinwa kunye nolawulo kunzima ngakumbi. kwaye ezintsonkothileyo, ke ngoko, akukho mfuneko zikhethekileyo kangangoko ukuphepha ukusetyenziswa.
