Miedzo yakaitwa pamusoro pekupokana uye kusimba kwehuremu hwesefa, uye shanduko yemitemo yeguruva inobata kuramba uye kugona kwesefa yakaongororwa, kushandiswa kwesimba kwesefa kwakaverengerwa zvinoenderana nemaitiro ekugadzirisa simba ekuverenga akakurudzirwa neEurovent 4. /11.
Inowanikwa kuti mutengo wemagetsi wesefa, unowedzera nekusimudzwa kwekushandisa-nguva uye kuramba.
Zvichienderana nekuongororwa kwemutengo wekutsiva sefa, mutengo wekushandisa uye mutengo wakakwana, nzira yekuona kuti sefa inofanira kutsiviwa riini inotsanangurwa.
Mhedzisiro yacho yakaratidza kuti hupenyu chaihwo hwesevhisi hwesefa hwakakwira kupfuura hwakatsanangurwa muGB/T 14295-2008.
Iyo nguva yekutsiviwa kwesefa mune yakajairika chivakwa chevanhu inofanirwa kusarudzwa zvichienderana nekutsiviwa kwemitengo yehuwandu hwemhepo uye mari yekushandisa simba rekushandisa.

Kurudziro yemhando yemhepo pahutano hwevanhu yave imwe yenyaya dzakanyanya kukosha kune nzanga.
Parizvino, kusvibiswa kwemhepo kwekunze kunomiririrwa nePM2.5 kwakakomba muChina. Naizvozvo, indasitiri yekuchenesa mweya inokura nekukurumidza, uye midziyo yekuchenesa mweya mutsva uye yekuchenesa mweya zvakashandiswa zvakanyanya.
Muna 2017, kuChina kunosvika zviuru mazana masere nemakumi matanhatu emhepo yekufefetera uye mamirioni manomwe ekuchenesa. Nekuziva kurinani kwePM2.5, mwero wekushandiswa kwemidziyo yekuchenesa unowedzera kuwedzera, uye munguva pfupi ichava mudziyo unodiwa muhupenyu hwezuva nezuva. Kukurumbira kwemhando iyi yemidziyo inokanganiswa zvakananga nemutengo wayo wekutenga uye mutengo wekumhanyisa, saka zvakakosha zvikuru kudzidza hupfumi hwayo.
Iwo makuru maparamendi esefa anosanganisira kudonha kwekumanikidza, huwandu hwezvimedu zvakaunganidzwa, kugona kwekuunganidza uye nguva yekumhanya. Nzira nhatu dzinogona kugamuchirwa kutonga sefa yekutsiva nguva yemhepo yakachena yekuchenesa. Yekutanga ndeyekuyera shanduko yekudzivirira pamberi uye mushure mesefa zvinoenderana nedhisheni inonzwa mudziyo; Chechipiri ndechekuyera kuwanda kwechinhu chiri paburiro zvichienderana nechinhu chinonzwa. Yekupedzisira ndeyekumhanya nguva, ndiko kuti, kuyera nguva yekumhanya yemidziyo.
Dzidziso yechinyakare yekutsiviwa kwesefa ndeyekuenzanisa mutengo wekutenga uye mutengo wekushandisa zvichienderana nekubudirira. Mune mamwe mazwi, kuwedzera kwekushandiswa kwesimba kunokonzerwa nekuwedzera kwekupikisa uye mari yekutenga.

Kutora fan frequency kutendeuka mumhepo duct system yerabhoritari kugadzirisa iyo inoshanda mhepo vhoriyamu yefirita, nekudaro kuyedza kuita kwesefa pasi pehuwandu hwemhepo.
1.2 Kuedza Sample
Kuti uwedzere kudzokorora kwekuyedza, mafirita matatu emhepo anogadzirwa nemugadziri mumwe chete akasarudzwa. Sezvo mafirita emhando yeH11, H12 neH13 anoshandiswa zvakanyanya pamusika, H11 giredhi sefa yakashandiswa mukuyedza uku, nehukuru hwe560mm×560mm×60mm, v-mhando yemakemikari faibha dense folding type, sezvakaratidzwa mumufananidzo 3.

Zvinoenderana nezvinodiwa zveGB/T 14295-2008 "Air Filter", mukuwedzera kune bvunzo mamiriro anodiwa muyedzo zviyero, zvinotevera zvinofanirwa kuverengerwa:
1) Panguva yekuyedzwa, tembiricha uye hunyoro hwemweya wakachena unotumira mune duct system inofanirwa kufanana;
2) Iyo guruva sosi inoshandiswa kuyedza ese masampuli anofanira kuramba akafanana.
3) Sample yega yega isati yaedzwa, guruva zvidimbu zvakaiswa muduti system zvinofanirwa kucheneswa nebhurashi;
4) Kunyora maawa ekushanda kwesefa panguva yekuedzwa, kusanganisira nguva yekubudisa uye kumiswa kweguruva;
