1.Zonke izinhlobo zezihlungi zomoya kanye nezihlungi zomoya ze-HEPA azivunyelwe ukudabula noma ukuvula isikhwama noma ifilimu yokupakisha ngesandla ngaphambi kokufakwa; isihlungi somoya kufanele sigcinwe ngokuhambisana ngokuqinile nesiqondiso esimakwe kuphakheji lesihlungi se-HEPA; kusihlungi somoya se-HEPA ngesikhathi sokuphatha, kufanele siphathwe ngobumnene ukuze kugwenywe ukudlidliza okunodlame nokungqubuzana.
I-2.Ezihlungi ze-HEPA, isiqondiso sokufaka kufanele silungile: lapho isihlungi senhlanganisela yepuleti likathayela sifakwe ngokuqondile, ipuleti likathayela kufanele libe yi-perpendicular emhlabathini; ukuxhumana phakathi kokuma okuqondile kanye nohlaka lwesihlungi kuvinjelwe ngokuqinile ekuvuzeni, ukuguqulwa, ukulimala kanye nokuvuza. Glue, njll, ngemva kokufakwa, udonga lwangaphakathi kufanele luhlanzeke, lungabi nothuli, amafutha, ukugqwala kanye nemfucumfucu.
3.Indlela yokuhlola: Qaphela noma usule ngendwangu kasilika emhlophe.
4. Ngaphambi kokuba kufakwe isihlungi esisebenza kahle kakhulu, igumbi elihlanzekile kufanele lihlanzwe kahle futhi lihlanzwe. Uma kunothuli ngaphakathi kwesistimu ye-air-conditioning, kufanele ihlanzwe futhi isulwe futhi ukuze ihlangabezane nezidingo zokuhlanza. Uma isihlungi esisebenza kahle kakhulu sifakwe ku-interlayer yezobuchwepheshe noma kusilingi, ungqimba lobuchwepheshe noma usilingi kufanele futhi kuhlanzwe kahle futhi kusulwe kuhlanzeke.
5. Ukuthuthwa nokugcinwa kwezihlungi ze-HEPA kufanele kubekwe endaweni yelogo yomkhiqizi. Ngesikhathi sokuthutha, kufanele kuphathwe ngobumnene ukuvimbela ukudlidliza okunodlame nokushayisana, futhi akuvunyelwe ukulayisha nokukhipha.
6. Ngaphambi kokufakwa kwesihlungi se-HEPA, iphakheji kufanele ikhishwe endaweni yokufaka ukuze ihlolwe, okuhlanganisa: iphepha lokuhlunga, i-sealant kanye nohlaka lomonakalo; ubude obuhlangothini, ubukhulu be-diagonal kanye nobukhulu buhlangene; ifreyimu ine-burr kanye ne-Rust spots (uhlaka lwensimbi); noma ngabe sikhona isitifiketi somkhiqizo, ukusebenza kobuchwepheshe kuhlangabezana nezidingo zokuklama. Khona-ke ngokuhambisana nezinga likazwelonke "lokwakhiwa kwegumbi elihlanzekile kanye nemininingwane yokwamukela" [JGJ71-90] indlela yokuhlola, abaqeqeshiwe kufanele bafakwe ngokushesha.
7. Isihlungi se-HEPA esinezinga lokuhlanzeka elilingana noma elingaphezu kwegumbi elihlanzekile Lekilasi Le-100. Ngaphambi kokufaka, kufanele iputshuzwe ngokwendlela eshiwo “Ekucacisweni Kokwakhiwa Kwezindlu Ezihlanzekile Nokwamukela” [JGJ71-90] futhi ihlangabezane nezimfuneko ezishiwo.
8. Uma ufaka isihlungi se-HEPA, umcibisholo osohlangothini lwangaphandle kufanele uhambisane nesiqondiso sokugeleza komoya; uma ifakwe iqonde, isiqondiso sephepha lesihlungi kufanele sibe perpendicular phansi.
9. Faka ipuleti elimahhadla noma isihlungi esigoqayo esinemeshi eyenziwe ngothayela ngasemuva komoya. Ukufaka isihlungi sesikhwama, ubude besikhwama sokuhlunga kufanele bube yi-perpendicular phansi, futhi isiqondiso sesikhwama sokuhlunga akufanele sifakwe ngokuhambisana nomhlabathi.
10. Ngaphansi kwezimo ezijwayelekile zokusetshenziswa, ipuleti eliyisicaba, isihlungi esigoqiwe esinamaqhafuqhafu noma esiphakathi, ngokuvamile sishintshwa kanye ngoJanuwari-Mashi, indawo lapho izidingo zingaqinile khona, izinto zokuhlunga zingashintshwa, bese zicwiliswa ngamanzi aqukethe okokuhlanza. Hlanza, bese usula futhi ubeke esikhundleni; ngemva kwezikhathi ezingu-1-2 zokugeza, isihlungi esisha kufanele sishintshwe ukuze kuqinisekiswe ukusebenza kahle kokuhlunga.
11. Ngohlobo lwesikhwama sokuhlunga amaholoholo noma aphakathi nendawo, ngaphansi kwezimo ezijwayelekile zokusetshenziswa (isilinganiso samahora angu-8 ngosuku, ukusebenza okuqhubekayo), esisha kufanele sishintshwe ngemva kwamasonto angu-7-9.
12. Izihlungi ze-sub-hepa, ngaphansi kwezimo ezijwayelekile zokusetshenziswa (isilinganiso samahora angu-8 ngosuku, ukusebenza okuqhubekayo), ngokuvamile okusetshenziselwa izinyanga ezingu-5-6, kufanele futhi kushintshwe.
13. Ngesihlungi esingenhla, uma kukhona i-gauge yengcindezi ehlukile noma inzwa yokucindezela okuhlukile ngaphambi nangemuva kwesihlungi, isihlungi esimahhadla kumele sishintshwe lapho umehluko wengcindezi umkhulu kuno-250Pa; ngesihlungi esiphakathi, ingcindezi ehlukile ingaphezu kuka-330Pa, kufanele ishintshwe; kuzihlungi ze-sub-hepa, lapho umehluko wengcindezi umkhulu kuno-400Pa, kufanele kushintshwe futhi isihlungi sangempela asikwazi ukuphinda sisetshenziswe.
14. Ezihlungi ze-HEPA, lapho inani lokumelana nesihlungi likhulu kuno-450Pa; noma lapho isivinini sokugeleza komoya endaweni ebheke ngasemoyeni sincishiswa, isivinini sokugeleza komoya asinakukhushulwa ngisho nangemva kokufaka isihlungi esimahhadla nesiphakathi; Uma kukhona ukuvuza okungenakulungiseka ebusweni besihlungi, isihlungi esisha se-HEPA kufanele kushintshwe. Uma izimo ezingenhla zingatholakali, zingashintshwa kanye njalo eminyakeni engu-1-2 kuye ngezimo zemvelo.
15. Ukuze unikeze ukudlala okuphelele endimeni yesihlungi, isivinini somoya esikhuphuka nomfula sesihlungi ngesikhathi sokukhethwa nokusetshenziswa, isihlungi esimahhadla nesiphakathi akufanele sidlule u-2.5m/s, futhi isihlungi se-sub-hepa nesihlungi esisebenza kahle kakhulu akufanele sidlule u-1.5. m / s, lokhu ngeke kusize kuphela ukuqinisekisa ukusebenza kahle kwesihlungi, kodwa futhi kwandise impilo yesihlungi nokugcina izindleko.
16. Uma okokusebenza kusebenza, ngokuvamile ungasishintshi isihlungi; uma isihlungi singashintshwanga ngenxa yesikhathi sokushintsha, izihlungi ezimahhadla nezimaphakathi kuphela ezingashintshwa esimweni sabalandeli abangami; isihlungi se-sub-hepa nesihlungi se-HEPA. Kufanele imiswe ngaphambi kokuthi ishintshwe.
17. I-gasket phakathi kwesihlungi kanye nefreyimu yokuxhuma kufanele iqine futhi ingavuzi ukuze kuqinisekiswe umphumela wokuhlunga.
18. Izihlungi ze-HEPA ezidinga ukusetshenziswa ezindaweni ezinomswakama ophezulu kanye nezinga lokushisa eliphezulu, amaphepha okuhlunga anezinga lokushisa eliphezulu kanye nokumelana nomswakama ophezulu, amapuleti okuhlukanisa kanye nezinto zohlaka kufanele zikhethwe ukuhlangabezana nezidingo zokukhiqiza.
19. Igumbi elihlanzekile lezinto eziphilayo kanye negumbi elihlanzekile lezokwelapha kumele lisebenzise isisefo sohlaka lwensimbi, futhi indawo engaphezulu akufanele igqwale kalula. Akuvunyelwe ukusebenzisa isihlungi sepuleti lohlaka lwamapulangwe ukuvimbela amagciwane futhi kuthinte umkhiqizo.
