Yakachena kamuri yekumhanyisa mhepo zvinodiwa uye shanduko yemhepo

Yakakwana ventilation vhoriyamu ndeyekunyorovesa uye kubvisa mukati memukati yakasviba mweya, zvinoenderana neyakasiyana hutsanana zvinodiwa, kanaimba yakachenaurefu hwemambure hwakakwirira, kuwedzera kwakakodzera kwenhamba yekuchinja kwemhepo. Pakati pawo, huwandu hwekufemesa hwemakamuri akachena miriyoni hunotariswa maererano nepamusoro-soro yekuchenesa system [7], uye mamwe anotariswa zvinoenderana nepamusoro-soro yekuchenesa system. Kana iyo 100,000-kirasi yakachena kamuri HEPA sefa yakarongedzerwa nechepakati mukamuri yemuchina kana kupera kwehurongwa, huwandu hwekuchinja kwemhepo hunogona kuwedzera zvakafanira ne10-20%.

Kune iyo iri pamusoro yakakurudzirwa kukosha kwevhoriyamu yemhepo, munyori anotenda kuti mhepo inomhanya kuburikidza nechikamu chekamuri cheiyo unidirectional.kuyerera yakachena imbayakaderera, uye mhirizhonga yakachena kamuri ndiyo inokurudzirwa kukosha ine yakazara chengetedzo chinhu. Vertical unidirectional flow ≥0.25m / s, horizontal unidirectional flow ≥0.35m / s, munzvimbo isina chinhu kana static kuonekwa kwehutsanana, kunyange zvazvo inogona kusangana nezvinodiwa, asi simba rinopesana nekusvibiswa kwakashata, kana mukati mukati mehurumende yekushanda, utsanana hunogona kusasangana nezvinodiwa, mienzaniso yakadaro haisi yega; Panguva imwecheteyo, China yeventilator yakatevedzana haisati yave yakanyatsokodzera kucheneswa kwe fan, mugadziri mukuru kazhinji haaverenge nemazvo kupikisa kwemhepo yehurongwa, kana kuterera kuti fan yakasarudzwa iri muchimiro chechimiro chenzvimbo inofarirwa yekushanda, kuitira kuti sisitimu ishandiswe munguva pfupi yapfuura, vhoriyamu yemhepo kana kumhanya kwemhepo haigone kusvika pakukosha kwekugadzira. Iyo United States Federal standard (FS209A ~ B) yakave yakatemerwa pamberi paGumiguru 27, 1987: Kumhanya kwemhepo kwekamuri isina unidirectional yakachena kuburikidza nechikamu chekamuri yakachena kunowanzo chengetwa pa9Oft/min(0.45m/s), uye pasi pemamiriro ekusavhiringidza mukamuri rese, kukurumidza kufanana kuri mukati me ± 20%. Chero kuderera kukuru kwekumhanya kwemhepo kunowedzera mukana wekusvibisa mhedzisiro pakati penguva yekuzvichenesa nenzvimbo yekushanda (zvese ma paramita kunze kwekuiswa kweguruva hazvitaurwe mushure mekushambadzwa kweFS209C muna Gumiguru 1987).

Kuti izvi zviitike, munyori anofunga kuti zvakakodzera kuwedzera iko zvino dhizaini kukosha kweiyo unidirectional kuyerera kumhanya, yedu unit mupurojekiti chaiyo kuita kudaro, mhedzisiro iri nani. Iyo turbulence type yakachena kamuri inokurudzirwa kukosha ine yakazara chengetedzo chinhu, asi vagadziri vazhinji havasati vavimbiswa kuti pakuita iyo chaiyo dhizaini, iyo 100,000 level yakachena kamuri yekufefetera vhoriyamu inowedzerwa kusvika 20 ~ 25 nguva / h, iyo 10,000 nhanho inowedzerwa kusvika 30 ~ 40 nguva / h, uye iyo 100,000 dhizaini inowedzera kusvika 1000 nhanho uye 1000 nhanho inowedzera kusvika 1000 nhanho uye 7000 nhanho inowedzera. mari yekutanga. Inowedzerawo mari yekugadzirisa nekugadzirisa mune ramangwana, uye hazvidikanwi kuita kudaro. Pakugadzirira China mhepo yekuchenesa hunyanzvi matanho [7], anopfuura zana emakamuri edzimba akachena akaongororwa uye kuyerwa, uye makamuri mazhinji akachena akange achiri kuedzwa pasi pemamiriro ekuchinja, uye mhedzisiro yakaratidza kuti vhoriyamu yekufemesa ye100,000 giredhi ≥10 giredhi ≥20 nguva / h, uye 5 giredhi zvinodiwa / ≥0 giredhi nguva / ≥0 giredhi nguva / ≥000 nguva / h00. The United States federal standard (FS2O9A~B) inotaura kuti isiri-unidirectional inoyerera yakachena kamuri (100,000 kirasi, 10,000 kirasi), kureba kwekamuri 8~l2ft(2.44~3.66m), kazhinji funga imba yese kamwechete kamwe pamaminitsi matatu (kureva, 20 nguva / h). Nokudaro, zvigadziro zvekugadzirwa kwemaitiro [6] zvakatora chikamu chikuru chehupfumi, uye mugadziri anogona kusarudza zvakachengeteka maererano nehuwandu hunokurudzirwa hwevheji yemhepo.
