Ukulawulwa kwevolumu yomfutho ohlukile kubalulekile ukuze kuqinisekiswe ukuhlanzeka kwegumbi elihlanzekile futhi kuvimbele ukusabalala kokungcola. Okulandelayo yizinyathelo ezicacile nezindlela zokulawula ivolumu yomoya ngokuhlukana kwengcindezi.
1. Inhloso eyisisekelo yokulawula ivolumu yomoya ngokwehluka kwengcindezi
Inhloso eyinhloko yokulawulwa komthamo womoya wokuhlukanisa ingcindezi iwukugcina umehluko othile wengcindezi emile phakathi kwegumbi elihlanzekile nendawo ezungezile ukuze kuqinisekiswe ukuhlanzeka kwegumbi elihlanzekile nokuvimbela ukusabalala kokungcola.
2. Isu lokulawula ukuhluka kwevolumu yomoya
(1). Nquma isidingo somehluko wengcindezi
Ngokuya ngezici zedizayini nezidingo zenqubo yokukhiqiza yegumbi elihlanzekile, nquma ukuthi umehluko wengcindezi phakathi kwegumbi elihlanzekile nendawo ezungezile kufanele ube muhle noma ube mubi. Umehluko wengcindezi phakathi kwamagumbi ahlanzekile amabanga ahlukene naphakathi kwezindawo ezihlanzekile nezindawo ezingahlanzekile akufanele ube ngaphansi kuka-5Pa, futhi umehluko wengcindezi phakathi kwendawo ehlanzekile nangaphandle akufanele ube ngaphansi kuka-10Pa.
(2). Bala ivolumu yomfutho womoya ohlukile
Ivolumu yomoya ovuzayo ingabalwa ngokulinganisa inani lezikhathi zokushintsha umoya wegumbi noma indlela yegebe. Indlela yegebe inengqondo kakhulu futhi inembe, futhi icabangela ukucinana komoya nendawo yegebe yesakhiwo esivalekile.
Ifomula yokubala: LC = µP × AP × ΔP × ρ noma LC = α × q × l, lapho i-LC ingumehluko wokucindezela ivolumu yomoya edingekayo ukuze kugcinwe inani lomehluko wengcindezi yegumbi elihlanzekile, µP i-coefficient yokugeleza, i-AP iyindawo yegebe, i-ΔP umehluko wengcindezi emile, ρ yi-αq yisilinganiso somoya seyunithi, ubude beyunithi yokuphepha wegebe, futhi l ubude begebe.
Indlela yokulawula yamukelwe:
① Indlela yokulawula ivolumu yomoya eqhubekayo (CAV): Okokuqala thola imvamisa yokusebenza yebhentshimakhi yesistimu yesipholile ukuze uqinisekise ukuthi umthamo womoya wokunikezela uhambisana nevolumu yomoya eklanyelwe. Nquma isilinganiso somoya omusha bese usilungisa sibe ivelu yokuklama. Lungisa i-engeli ye-air damper ebuyayo yephaseji ehlanzekile ukuze uqinisekise ukuthi umehluko we-corridor pressure ungaphakathi kwebanga elifanele, elisetshenziswa njenge-benchmark yokulungisa umehluko wengcindezi kwamanye amagumbi.
② Indlela yokulawula ivolumu yomoya eguquguqukayo (VAV): Lungiselela ngokuqhubekayo umthamo womoya wokuhlinzeka noma khipha ivolumu yomoya ngokusebenzisa isidambisi-moya sikagesi ukuze ugcine ingcindezi oyifunayo. Indlela yokulawula ingcindezi ehlukile (i-OP) isebenzisa inzwa yengcindezi ehlukile ukuze ilinganise umehluko wengcindezi phakathi kwegumbi nendawo eyinkomba, futhi iyiqhathanise nendawo ebekiwe, futhi ilawula ivolumu yomoya wokunikezela noma ivolumu yomoya wokukhipha umoya nge-algorithm yokulungisa ye-PID.
Ukugunyazwa nokugcinwa kwesistimu:
Ngemuva kokufakwa kwesistimu, ukuthunyelwa kwebhalansi yomoya kwenziwa ukuze kuqinisekiswe ukuthi umthamo womoya ohlukile uhlangabezana nezidingo zokuklama. Hlola njalo futhi unakekele isistimu, okuhlanganisa izihlungi, izifeni, ama-air dampers, njll., ukuze uqinisekise ukusebenza kwesistimu okuzinzile.
3. Isifinyezo
Ukulawulwa kwevolumu yokucindezela okuhlukile kuyisixhumanisi esibalulekile ekwakhiweni nasekuphathweni kwegumbi elihlanzekile. Ngokunquma isidingo somehluko wengcindezi, ukubala umehluko wengcindezi yomthamo womoya, ukusebenzisa izindlela ezifanele zokulawula, nokuthumela nokugcina uhlelo, ukuhlanzeka nokuphepha kwegumbi elihlanzekile kungaqinisekiswa futhi ukusabalala kokungcola kungavinjelwa.
