UNGAYILAWULA KANJANI INQANDELO YOMOYA ENGAHLUKILE EGUMBINI ELIHLANZEKILE?

Ukulawulwa komthamo womoya ocindezelwe ngokwehlukana kubalulekile ukuqinisekisa ukuhlanzeka kwegumbi elihlanzekile nokuvimbela ukusabalala kokungcola. Nazi izinyathelo nezindlela ezicacile zokulawula umthamo womoya ukuze kuhlukaniswe umfutho.

1. Inhloso eyisisekelo yokulawula ivolumu yomoya ehlukanisiwe

Inhloso eyinhloko yokulawula ivolumu yomoya eguquguqukayo iwukugcina umehluko othile wokucindezela ozinzile phakathi kwegumbi elihlanzekile nendawo ezungezile ukuqinisekisa ukuhlanzeka kwegumbi elihlanzekile nokuvimbela ukusabalala kokungcola.

2. Isu lokulawula ivolumu yomoya eguquguqukayo

(1). Nquma isidingo somehluko wokucindezela

Ngokwezincazelo zomklamo kanye nezidingo zenqubo yokukhiqiza yegumbi elihlanzekile, nquma ukuthi umehluko wokucindezela phakathi kwegumbi elihlanzekile nendawo ezungezile kufanele ube muhle noma mubi. Umehluko wokucindezela phakathi kwamakamelo ahlanzekile ezinhlobo ezahlukene kanye naphakathi kwezindawo ezihlanzekile nezindawo ezingahlanzekile akufanele ube ngaphansi kwama-5Pa, kanye nomehluko wokucindezela phakathi kwendawo ehlanzekile nengaphandle akufanele ube ngaphansi kwama-10Pa.

(2). Bala ivolumu yomoya ocindezelekile ohlukile

Umthamo womoya ovuzayo ungabalwa ngokulinganisa inani lezikhathi zokushintsha umoya wegumbi noma indlela yegebe. Indlela yegebe inengqondo futhi inembile, futhi icabangela ukuqina komoya nendawo yegebe yesakhiwo esivalekile.

Ifomula yokubala: LC = µP × AP × ΔP × ρ noma LC = α × q × l, lapho i-LC ingumehluko womoya odingekayo ukuze kulondolozwe umehluko wokucindezela wegumbi elihlanzekile, i-µP iyi-flow coefficient, i-AP yindawo yegebe, i-ΔP ingumehluko wokucindezela okungaguquki, i-ρ iyi-density yomoya, i-α iyisici sokuphepha, i-q iyivolumu yomoya ovuzayo ngobude beyunithi ngayinye yegebe, kanye ne-l ubude begebe.

Indlela yokulawula eyamukelwe:

① Indlela yokulawula ivolumu yomoya engaguquki (i-CAV): Okokuqala nquma imvamisa yokusebenza kwesistimu yokupholisa umoya ukuqinisekisa ukuthi ivolumu yomoya ophakelwayo ihambisana nevolumu yomoya eklanyiwe. Thola isilinganiso somoya omusha bese usilungisa ngokwenani lomklamo. Lungisa i-engeli ye-return air damper ye-corridor ehlanzekile ukuqinisekisa ukuthi umehluko wengcindezi ye-corridor ungaphakathi kwebanga elifanele, elisetshenziswa njengesilinganiso sokulungiswa komehluko wengcindezi kwamanye amakamelo.

② Indlela yokulawula ivolumu yomoya eguquguqukayo (i-VAV): Lungisa njalo ivolumu yomoya ophakelwayo noma ivolumu yomoya ophumayo nge-damper yomoya kagesi ukuze ugcine ingcindezi oyifunayo. Indlela yokulawula ingcindezi ehlukene (i-OP) isebenzisa inzwa yokucindezela ehlukene ukukala umehluko wokucindezela phakathi kwegumbi nendawo yokubhekisela, bese iyiqhathanisa nephuzu elibekiwe, bese ilawula ivolumu yomoya ophakelwayo noma ivolumu yomoya ophumayo nge-algorithm yokulungisa i-PID.

Ukuqaliswa kanye nokugcinwa kwesistimu:

Ngemva kokufakwa kwesistimu, kwenziwa ukuqaliswa kwebhalansi yomoya ukuqinisekisa ukuthi ivolumu yomoya eguquguqukayo ihlangabezana nezidingo zomklamo. Hlola futhi ulondoloze uhlelo njalo, okuhlanganisa izihlungi, amafeni, ama-air dampers, njll., ukuqinisekisa ukusebenza kahle kwesistimu.

3. Isifinyezo

Ukulawulwa komthamo womoya ocindezelwe ngokwehlukana kuyisixhumanisi esibalulekile ekwakhiweni nasekuphathweni kwegumbi elihlanzekile. Ngokunquma isidingo somehluko wokucindezela, ukubala umthamo womoya ocindezelwe ngokwehlukana, ukusebenzisa izindlela zokulawula ezifanele, kanye nokuqalisa nokugcina uhlelo, ukuhlanzeka nokuphepha kwegumbi elihlanzekile kungaqinisekiswa futhi ukusabalala kokungcola kungavinjelwa.
