Kukosha kwakakodzera kwehuwandu hwemhepo inopihwa muimba yekugezera hakuna kugadzika, asi zvinoenderana nezvinhu zvakawanda, kusanganisira huwandu hwekuchena, nzvimbo, kureba, huwandu hwevashandi, uye zvinodiwa pakushanda kwenzvimbo yekugezera. Izvi zvinotevera nhungamiro dzakavakirwa pakufunga kwakazara kwezvinhu zvakasiyana.
1. Kuchena
Sarudza huwandu hwekuchinja kwemhepo zvichienderana nehuwandu hwehutsanana: Huwandu hwekuchinja kwemhepo muimba yekugezera ndechimwe chezvinhu zvakakosha pakuona huwandu hwemhepo inopihwa. Zvichienderana nemitemo yakakodzera, dzimba dzekugezera dzine mwero wakasiyana wehutsanana dzine zvinodiwa zvakasiyana zvekuchinja mweya. Semuenzaniso, imba yekugezera yekirasi 1000 haipfuure ka50/awa, imba yekugezera yekirasi 10000 haipfuure ka25/awa, uye imba yekugezera yekirasi 100000 haipfuure ka15/awa. Nguva idzi dzekuchinja mhepo dzinodiwa zvisingachinji, uye imwe nzvimbo inogona kusiiwa muchimiro chaicho kuti ive nechokwadi chekuchena kwenzvimbo yekugezera yakachena.
ISO 14644 standard: Iyi standard ndeimwe yemitemo inoshandiswa zvakanyanya mu cleanroom air voltage uye air speed pasi rose. Sekureva kweISO 14644 standard, cleanrooms dzine mazinga akasiyana dzine zvinodiwa zvakasiyana zve air voltage uye air speed. Semuenzaniso, ISO 5 cleanroom inoda air speed ye0.3-0.5m/s, nepo ISO 7 cleanroom ichida air speed ye0.14-0.2m/s. Kunyangwe zvinodiwa zve air speed izvi zvisingaenzane zvakakwana ne air voltage, zvinopa chirevo chakakosha chekuona air voltage.
2. Nzvimbo yekushandira uye kukwirira
Verenga huwandu hwenzvimbo yakachena yekushandira: Kuverenga huwandu hwemhepo inopihwa kunofanirwa kufunga nezvenzvimbo nekukwirira kwenzvimbo yekushandira kuti uone huwandu hwese hwenzvimbo yekushandira. Shandisa fomura V = kureba*upamhi*kukwirira kuti uverenge huwandu hwenzvimbo yekushandira (V ihuwandu mumamita ecubic).
Verenga huwandu hwemhepo inopihwa pamwe chete nehuwandu hwemhepo inoshandurwa: Zvichibva pahuwandu hwebasa uye huwandu hunodiwa hwemhepo inoshandurwa, shandisa fomura Q = V*n kuti uverenge huwandu hwemhepo inopihwa (Q ihuwandu hwemhepo inopihwa muma cubic metres paawa; n inhamba yemhepo inoshandurwa).
3. Zvinodiwa nevashandi uye maitiro
Zvinodiwa pahuwandu hwemhepo yakachena yevashandi: Zvichienderana nehuwandu hwevashandi vari mukamuri rekuchenesa, huwandu hwemhepo itsva hwese hunoverengerwa zvichienderana nehuwandu hwemhepo itsva hunodiwa pamunhu (kazhinji 40 cubic metres pamunhu paawa). Huwandu hwemhepo itsva uhwu hunofanira kuwedzerwa pahuwandu hwemhepo inopihwa huchiverengerwa zvichienderana nehuwandu hwebasa uye shanduko dzemhepo.
Kubhadhara huwandu hwemhepo inobuda mumagetsi: Kana paine michina yekugadzira mukamuri rekugezesa inoda kupedzerwa, huwandu hwemhepo inobuda mumagetsi hunofanira kubhadharwa zvichienderana nehuwandu hwemhepo inobuda mumagetsi kuti mhepo irambe yakaenzana munzvimbo yakachena.
4. Kuziva kwakakwana kwehuwandu hwemhepo inopihwa
Kufunga zvakadzama nezvezvinhu zvakasiyana-siyana: Pakusarudza huwandu hwemhepo inobuda mumba yekugezera, zvinhu zvese zviri pamusoro apa zvinofanirwa kutariswa zvizere. Panogona kunge paine kupindirana uye kuganhurirana pakati pezvinhu zvakasiyana, saka ongororo yakazara uye kutengeserana zvinodiwa.
Kuchengetedzwa kwenzvimbo: Kuti imba yekugezera ive yakachena uye igare yakagadzikana, huwandu hwakati hwemhepo inowanzosiyiwa mudhizaini chaiyo. Izvi zvinogona kugadzirisa matambudziko enjodzi kana shanduko dzemaitiro pahuwandu hwemhepo inopihwa kusvika pamwero wakati.
Muchidimbu, huwandu hwemhepo inobuda muimba yekugezera hauna kukosha kwakakodzera, asi unofanirwa kuongororwa zvizere zvichienderana nemamiriro chaiwo enzvimbo yekugezera yakachena. Pakushanda chaiko, zvinokurudzirwa kubvunza kambani yehunyanzvi yeinjiniya yemakamuri ekugezera kuti ive nechokwadi chekuti huwandu hwemhepo inobuda hunoshanda uye hwakarongeka.
