Isihluzi somoya sisixhobo esingundoqo senkqubo yokucoca umoya womoya. Isihluzi sidala ukuxhathisa emoyeni. Njengoko uthuli lokucoca lukhula, ukuxhathisa isihluzo kuya kwanda. Xa isihluzi sinothuli kakhulu kwaye ukuxhathisa kuphezulu kakhulu, isihluzo siya kuncitshiswa ngumthamo womoya, okanye isihluzo siya kungena ngokuyinxenye. Ngoko ke, xa ukuxhathisa kwesihluzi kunyuka kwixabiso elithile, isihluzo siya kuchithwa. Ke ngoko, ukusebenzisa isihluzo, kufuneka ube nomjikelo wobomi ofanelekileyo. Kwimeko apho isihluzo singonakaliswanga, ubomi benkonzo ngokuqhelekileyo bunqunywe ngokuchasa.
Ubomi benkonzo yokucoca kuxhomekeke kwizinto eziluncedo kunye nezingeloncedo, ezifana: izinto zokucoca, indawo yokucoca, ukwakhiwa kwesakhiwo, ukuchasana kokuqala, njl njl. Kwakhona kuhambelana nokugxininiswa kothuli emoyeni, umthamo womoya wangempela, kunye nokusekwa kokumelana kokugqibela.
Ukuqonda umjikelo wobomi ofanelekileyo, kuya kufuneka uqonde utshintsho ekuchaseni kwayo. Okokuqala, kufuneka uqonde ezi nkcazo zilandelayo:
I-1. Ilinganiswe ukuchasana kokuqala: Ukuchasana kokuqala okubonelelwa ngesampulu yokucoca, i-curve yesici sokucoca okanye ingxelo yovavanyo lokucoca phantsi komthamo womoya.
2. Ukuchasana kokuqala koyilo: ukuchasana kokucoca phantsi koyilo lwenkqubo umthamo womoya (kufuneka unikezwe ngumyili wenkqubo yomoya).
3. Ukuchasana kokuqala kokusebenza: ekuqaleni kwenkqubo yokusebenza, ukuchasana kwesihluzi. Ukuba akukho sixhobo sokulinganisa uxinzelelo, ukuchasana phantsi komthamo womoya woyilo kunokuthathwa kuphela njengento yokuqala yokuchasana nokusebenza (umthamo womoya osebenzayo awukwazi ukulingana ngokupheleleyo nomthamo womoya woyilo);
Ngethuba lokusebenza, ukuchasana kwesihluzi kufuneka kuhlolwe rhoqo ukuze kudlule ukuchasana kokuqala (isixhobo sokujonga ukuchasana kufuneka sifakwe kwicandelo ngalinye lokucoca) ukugqiba ixesha lokubuyisela isihluzo. Umjikelo wokubuyisela wesihluzi, bona itheyibhile engezantsi (ireferensi kuphela):
| Udidi | Jonga umxholo | Umjikelo wokutshintshwa |
| Isihluzi sokungenisa umoya omtsha | Ngaba umnatha uvaliwe ngaphezu kwesiqingatha | Tshayela kanye ngeveki okanye njalo |
| Isihluzo esirhabaxa | Ukuchasana kugqithise ukuchaswa kokuqala okulinganiselwe malunga ne-60Pa, okanye ilingana ne-2 × ukuyila okanye ukuchasana kokuqala. | Iinyanga ezi-1-2 |
| Isihluzo esiphakathi | Ukuchasana kudlule ukuchasana kokuqala kwe-80Pa, okanye ilingana ne-2 × ukuyila okanye ukuchasana kokuqala | Iinyanga ezi-2-4 |
| Isihluzi se-Sub-HEPA | Ukuchasana kudlule ukuchasana kokuqala okulinganiselwe malunga ne-100 Pa, okanye ilingana ne-2 × ukuyila okanye ukuqhuba ukuchasana kokuqala (ukuchasana okuphantsi kunye ne-HEPA ngamaxesha e-3) | Ngaphezulu konyaka omnye |
| Isihluzi se-HEPA | Ukuchasana kudlule ukuchasana kokuqala kwe-160Pa, okanye ilingana ne-2 × ukuyila okanye ukuchasana kokuqala. | Ngaphezu kweminyaka emi-3 |
Inqaku elikhethekileyo: isihluzo esisebenza kancinci siqhele ukusebenzisa imathiriyeli yokucoca ifayibha erhabaxa, umsantsa phakathi kwemicu mkhulu, kwaye ukuxhathisa okugqithisileyo kunokuvuthela uthuli kwisihluzo. Kule meko, ukuxhathisa isihluzi akusanyuki, kodwa ukusebenza kakuhle kokucoca Kuphantse kube zero, ngoko ke lawula ngokungqongqo ukuchasana kokugqibela kwesihluzo esirhabaxa!
Kukho izinto ezininzi ekufuneka ziqwalaselwe xa kumiselwa ukuxhathisa okokugqibela. Ukuxhathisa okokugqibela kuphantsi, ubomi benkonzo bufutshane, kwaye iindleko zokubuyisela ixesha elide (iindleko zokucoca, iindleko zabasebenzi, kunye neendleko zokulahla) ziphezulu ngokuhambelanayo, kodwa ukusetyenziswa kwamandla okusebenzayo kuphantsi, ngoko ke isihluzo ngasinye kufuneka sibe nelona xabiso loqoqosho lokugqibela.
Ixabiso lokugqibela elicetyiswayo lokuxhathisa:
| Ukusebenza kakuhle | Kucetyiswa uxhathiso lokugqibela Pa |
| G3 (Erhabaxa) | 100-200 |
| G4 | 150~250 |
| F5~F6(Phakathi) | 250~300 |
| F7~F8(HEPA kunye nePhakathi) | 300~400 |
| F9~H11(Sub-HEPA) | 400~450 |
| HEPA | 400~600 |
Okukhona isihluzo simdaka, kokukhona sikhula ngokukhawuleza ukuxhathisa. Ukuxhathisa okuphezulu ngokugqithisileyo akuthethi ukuba ubomi bokucoca buya kwandiswa, kwaye ukuxhathisa ngokugqithiseleyo kuya kubangela ukuba inkqubo yokupholisa umoya ibe nokuhla okubukhali kumthamo womoya. Ukuxhatshazwa okuphezulu okugqithisileyo akukhuthazwa.
