Ulawulo lomthamo womoya oxinzelelweyo ngokwahlukeneyo lubalulekile ukuqinisekisa ukucoceka kwegumbi elicocekileyo nokuthintela ukusasazeka kongcoliseko. La manyathelo acacileyo kunye neendlela zokulawula umthamo womoya ukuze kubekho umahluko woxinzelelo.
1. Injongo esisiseko yokulawula ivolumu yomoya eyahlukileyo yoxinzelelo
Injongo ephambili yokulawula umthamo womoya owahlukileyo kukugcina umahluko othile woxinzelelo phakathi kwegumbi elicocekileyo nendawo ejikelezileyo ukuqinisekisa ukucoceka kwegumbi elicocekileyo nokuthintela ukusasazeka kongcoliseko.
2. Icebo lokulawula ivolumu yomoya eyahlukileyo yoxinzelelo
(1). Chonga imfuneko yomahluko woxinzelelo
Ngokweenkcazo zoyilo kunye neemfuno zenkqubo yokuvelisa igumbi elicocekileyo, misela ukuba umahluko woxinzelelo phakathi kwegumbi elicocekileyo nendawo ejikelezileyo kufuneka ube mhle okanye umbi. Umahluko woxinzelelo phakathi kwamagumbi acocekileyo anemigangatho eyahlukeneyo kunye naphakathi kweendawo ezicocekileyo kunye neendawo ezingacocekanga akufuneki ube ngaphantsi kwe-5Pa, kwaye umahluko woxinzelelo phakathi kwendawo ecocekileyo kunye neyangaphandle akufuneki ube ngaphantsi kwe-10Pa.
(2). Bala umthamo womoya oxinzelelweyo
Umthamo womoya ovuzayo ungabalwa ngokuqikelela inani lamaxesha okutshintsha komoya kwigumbi okanye indlela yesithuba. Indlela yesithuba ifanelekile kwaye ichanekile, kwaye ithathela ingqalelo ukuqina komoya kunye nendawo yesithuba sesakhiwo esibiyelweyo.
Ifomula yokubala: LC = µP × AP × ΔP × ρ okanye LC = α × q × l, apho i-LC ingumthamo womoya ofunekayo ukugcina ixabiso lomahluko woxinzelelo kwigumbi elicocekileyo, µP yi-flow coefficient, i-AP yindawo yesithuba, i-ΔP ngumahluko woxinzelelo olungaguqukiyo, i-ρ yingxinano yomoya, i-α yinto yokhuseleko, u-q ngumthamo womoya ovuzayo ngobude beyunithi yesithuba, kwaye u-l bubude besithuba.
Indlela yolawulo eyamkelweyo:
① Indlela yokulawula ivolumu yomoya rhoqo (i-CAV): Okokuqala misela ubungakanani bokusebenza kwenkqubo yomoya ukuqinisekisa ukuba ivolumu yomoya okhoyo iyahambelana nomthamo womoya oyilelweyo. Misela umlinganiselo womoya omtsha kwaye uwulungelelanise nexabiso loyilo. Lungisa i-engile ye-return air damper ye-corridor ecocekileyo ukuqinisekisa ukuba umahluko woxinzelelo lwe-corridor ungaphakathi koluhlu olufanelekileyo, olusetyenziswa njengomlinganiselo wokulungiswa komahluko woxinzelelo kwamanye amagumbi.
② Indlela yokulawula ivolumu yomoya eguquguqukayo (VAV): Lungisa rhoqo ivolumu yomoya ophakelwayo okanye ivolumu yomoya ophumayo ngedamper yombane ukuze ugcine uxinzelelo olufunekayo. Indlela yokulawula ingcinezelo eyahlukileyo (OP) isebenzisa isenzi soxinzelelo oluhlukileyo ukulinganisa umahluko woxinzelelo phakathi kwegumbi nendawo yesalathiso, kwaye iyithelekise nendawo ebekiweyo, kwaye ilawula ivolumu yomoya ophakelwayo okanye ivolumu yomoya ophumayo nge-algorithm yohlengahlengiso lwe-PID.
Ukuqaliswa kunye nokugcinwa kwenkqubo:
Emva kokuba inkqubo ifakiwe, kwenziwa ukuqaliswa kokulinganisela komoya ukuqinisekisa ukuba umthamo womoya oxinzelelweyo uyahlangabezana neemfuno zoyilo. Jonga kwaye ugcine inkqubo rhoqo, kuquka izihluzi, iifeni, ii-air dampers, njl.njl., ukuqinisekisa ukusebenza kakuhle kwenkqubo.
3. Isishwankathelo
Ulawulo lomthamo womoya oxinzelelweyo lukhonkco eliphambili kuyilo nolawulo lwegumbi elicocekileyo. Ngokumisela imfuno yomahluko woxinzelelo, ukubala umahluko womoya oxinzelelweyo, ukusebenzisa iindlela ezifanelekileyo zokulawula, kunye nokuqalisa nokugcina inkqubo icocekile, ucoceko nokhuseleko lwegumbi elicocekileyo lunokuqinisekiswa kwaye ukusasazeka kongcoliseko kunokuthintelwa.
