Dzimba dzekuchenesa dzakagadzirwa kuti dzichengetedze kutonga kwakasimba pamusoro pezvakatipoteredza, asi dzinoshanda chete kana dziine hunyanzvi hwekufambisa mhepo pateni kuti dzivabatsire kusvika padanho rehutsanana rinodiwa uye ISO classification standard.ISO Gwaro 14644-4 rinotsanangura mafambiro emhepo kuti ashandiswe mudzimba dzakachena pamatanho akasiyana-siyana kuitira kuchengetedza zvimedu zvinofambiswa nemhepo uye kuchena.
Cleanroom airflow inofanira kubvumira mhepo iri mukati meimba yekuchenesa kuti ichinje zvachose kubvisa zvimedu uye zvinosvibisa zvingangoitika zvisati zvagadzikana.Kuti uite izvi nemazvo, maitiro ekufambisa kwemhepo anofanira kunge akafanana - kuve nechokwadi chekuti chikamu chose chenzvimbo chinogona kusvikwa nemhepo yakachena, yakasefa.
Kuti tiputse kukosha kwekufanana kwemhepo yekuchenesa mukamuri, tinoda kutanga nekutarisa mhando nhatu huru dzekuyerera kwemhepo mudzimba dzakachena.
#1 UNIDIRECTIONAL CLEANROOM AIRFLOW
Iyi mhando yemhepo yekuchenesa imba inofamba ichienda kune imwe nzira mukamuri, ingave yakatwasuka kana yakatwasuka kubva kune fan mafirita mayunitsi kuenda kune exhaust system inobvisa "tsvina" mweya.Unidirectional kuyerera kunoda kukanganisa kuduku sezvinobvira kuchengetedza yunifomu muenzaniso.
#2 ISISIRI-UNIDIRECTIONAL CLEANROOM AIRFLOW
Mune isiri-unidirectional airflow pateni, mhepo inopinda mukamuri yekuchenesa kubva kumasefa mayuniti ari munzvimbo dzakawanda, angave akapatsanurwa mukamuri rose kana akaungana pamwechete.Pachine nzvimbo dzekupinda nekubuda dzakarongwa kuti mweya ufambe munzira dzinopfuura imwe.
Kunyangwe mhando yemhepo isinganyanyi kukosha kana ichienzaniswa neunidirectional airflow cleanrooms, kutarisisa kwakanyanya kunofanirwa kubhadharwa kuti uve nechokwadi chekuti mweya wanyatsoshandurwa, kuderedza mukana we "nzvimbo dzakafa" mukati meimba yakachena.
#3 MIXED CLEANROOM AIRFLOW
Musanganiswa wemhepo unoyerera unobatanidza zvese unidirectional uye isiri-unidirectional airflow.Unidirectional airflow inogona kushandiswa munzvimbo dzakananga kusimbisa dziviriro dzakatenderedza nzvimbo dzekushanda kana zvimwe zvinhu zvinonzwisa tsitsi, nepo isiri-unidirectional airflow ichiri kutenderera yakachena, yakasefa mweya mukati mekamuri yese.
Kunyangwe mhepo yakachena mukamuri yekuyerera isina unidirectional, isiri-unidirectional, kana yakasanganiswa,kuva neuniform cleanroom airflow pattern zvine basa.Dzimba dzekuchenesa dzinoitirwa kudzorwa nharaunda uko masisitimu ese anofanirwa kushanda kudzivirira nzvimbo dzinogona kuungana zvinosvibisa - kuburikidza nenzvimbo dzakafa kana mhirizhonga.
Nzvimbo dzakafa inzvimbo dzine mhepo ine mhirizhonga kana kusashandurwa uye zvinogona kukonzera kuiswa zvimedu kana kuunganidzwa kwezvinosvibisa.Mhepo ine bongozozo muimba yakachena inotyisawo kune utsanana.Mhepo ine mhirizhonga inoitika kana mhepo inoyerera isina kufanana, iyo inogona kukonzerwa nekumhanya kusina kufanana kwemhepo inopinda mukamuri kana zvipingamupinyi munzira yemhepo inopinda kana kubuda.
