Yakachena mukamuri yekumhanya kwemhepo 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 kuona kwehutsanana, kunyangwe ichigona kuzadzisa zvinodiwa, asi iyo anti-kusvibiswa kugona haina kunaka, kana iyo yemukati ichipinda munzvimbo yekushanda. , utsanana hunogona kusasangana nezvinodiwa, mienzaniso yakadaro haisi yega; Panguva imwecheteyo, China yeventilator yakatevedzana haisati yave yakakodzera kune yekuchenesa sisitimu ye fan, iyo general mugadziri kazhinji haaverenge nemazvo kupikisa kwemhepo kweiyo system, kana kusaterera kuti fan yakasarudzwa iri mu hunhu curve yeinonyanya kufarirwa nzvimbo yekushanda, kuitira kuti sisitimu iiswe mukushanda munguva pfupi yapfuura, vhoriyamu yemhepo kana kumhanya kwemhepo haigone kusvika pakukosha kwekugadzira. Iyo United States Federal standard (FS209A ~ B) yakatemerwa pamberi paGumiguru 27, 1987: Kumhanya kwemhepo kwekamuri yakachena isina unidirectional kuburikidza nechikamu chekamuri yakachena inowanzochengetwa pa9Oft/min(0.45m/s), uye pasi pemamiriro ezvinhu. yekusavhiringidza mukamuri yese, 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 mukamuri yekufefetera vhoriyamu inowedzerwa kusvika makumi maviri ~ 25 nguva / h, iyo 10,000 level iri. yakawedzera kusvika ku30 ~ 40 nguva / h, uye chiyero che1000 chinowedzera kusvika 60 ~ 70 nguva / h, izvo zvisingangowedzere simba rekushandisa uye zvinowedzera mari yekutanga. Inowedzerawo mari yekugadzirisa nekugadzirisa mune ramangwana, uye hazvidikanwi kuita kudaro. Pakugadzirira China yekuchenesa mhepo tekinoroji matanho [7], anopfuura zana edzimba akachena makamuri akaongororwa uye kuyerwa, uye makamuri mazhinji akachena akange achiri kuedzwa pasi pemamiriro ekuchinja, uye mhedzisiro yakaratidza kuti vhoriyamu yemhepo ye100,000 giredhi ≥10 nguva / h, 10,000 giredhi ≥20 nguva / h, uye 1000 giredhi ≥50 nguva / h inogona kusangana nezvinodiwa. 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 kamuri rese kamwechete kamwe pamaminitsi matatu ( ndiko kuti, ka20/h). Nokudaro, zvigadziro zvekugadzirwa kwemaitiro [6] zvakatora chikamu chikuru chehupfumi, uye mugadziri anogona kusarudza zvakachengeteka maererano nehuwandu hunokurudzirwa hwevheji yemhepo.
