ʻO ka paipu hoʻolako ea maʻamau o ka ea ea waena e hana mau ʻia me ka ʻili hao a i ʻole ke aniani fiber i hoʻoikaika ʻia i ka plastik ma ka ʻaoʻao o loko, i ʻōwili ʻia me nā mea insulation thermal, a ua wahī ʻia me ka pahu alumini ma ka papa o waho, kahi e kaumaha ai ka paipu ea i ke kaumaha. , ka hana a me ka manawa i ke kūkulu ʻana a me ka hoʻokomo ʻana, ʻilihune i ka nānā ʻana, haʻahaʻa i ka paʻa o ka ea a me ka nui o ka ikehu.Ke hoʻohālikelike ʻia me nā ʻauwaʻa ea kuʻuna, loaʻa nā pono ea phenolic composite:
1. Hiki ke hoʻohaʻahaʻa i ka wela wela o ka ea
ʻO ka thermal conductivity o ka phenolic composite air duct he 0.016 ~ 0.036w / (m · K), ʻoiai ʻoi aku ka nui o ka conductivity thermal o ka galvanized steel duct a me FRP duct.Eia kekahi, ʻo ke ʻano pili like ʻole o ka phenolic composite air duct e hōʻoia i ka paʻa maikaʻi o ka ea o ka ʻōnaehana hoʻoheheʻe, kahi kokoke i 8 mau manawa o ka duct steel galvanized.Hōʻike kekahi mau ʻikepili i ka wā e hoʻoili ʻia ai ka nui o ka wela (anu), ʻo ka pau ʻana o ka wela o ka paipu kila galvanized he 15%, ka nalowale o ka wela o ka paipu FRP he 8%, a me ka nalowale o ka wela o ka phenolic foam insulation material ea. ʻO ka paipu ma lalo o 2%.
2. Maikaʻi ka hāmau ʻana.
ʻO ka interlayer o phenolic aluminika foil composite air duct wall he perforated phenolic foam material plate, nona ka hana hoʻopau leo maikaʻi.I loko o ka ʻōnaehana hoʻoheheʻe ea, ʻo ka walaʻau i hana ʻia e ka ea ea i ka wā o ka hana ʻana ma ka laulā o 50-79db, i hoʻouna ʻia ma o ka paipu lako ea e hana i ka walaʻau i loko.ʻO Phenolic aluminum foil composite air duct nona iho he paipu muffler maikaʻi loa, a ʻaʻohe pono e hoʻonohonoho i nā mea hana e like me ka uhi ʻana a me ka kuʻekuʻe lima.
3. ʻO ke kaumaha māmā, hiki ke hoʻemi i ka ukana hale, a maʻalahi ka hoʻokomo
ʻO ke kaumaha o ka phenolic aluminum foil composite air duct he māmā, ma kahi o 1.4 kg / m2, aʻo ka nui o ke kaumaha o ka galvanized steel sheet air duct (0.8 mm mānoanoa) a me ka FRP air duct (3 mm mānoanoa) he 7.08 kg / m2 a me 15 ~ ʻO 20 kg / m2 kēlā me kēia, hiki ke hoʻemi nui i ka ukana o ka hale a he mea maikaʻi loa ia i ka hoʻokomo ʻana i ka duct air.I ka wā o ka hoʻokomo ʻana, hoʻokahi wale nō kākoʻo e koi ʻia i kēlā me kēia 4 m a i ʻole e loaʻa ka ikaika kākoʻo kūpono.Hoʻemi nui kēia i nā koi o nā kākoʻo a me nā hangers, e hana maʻalahi i ka lawe ʻana a me ke kau ʻana.
4. Paʻa a lōʻihi ke ola lawelawe
He maʻalahi ka ʻōpala i ka pā kila Galvanized i loko o ka wai, ʻoiai ke aniani fiber reinforced plastic maʻalahi i ka ʻelemakule a me ka pōʻino.No laila, ʻaʻole lōʻihi ke ola lawelawe o nā lewa maʻamau, ma kahi o 5-10 mau makahiki.ʻO ke ola lawelawe o ka papa insulation i uhi ʻia e nā ducts ea kuʻuna, e like me ka huluhulu aniani, he 5 mau makahiki wale nō, ʻoiai ʻo ke ola lawelawe o ka phenolic aluminum foil composite air ducts he 20 mau makahiki.No laila, ʻoi aku ka ʻoi aku o ke ola lawelawe o ka phenolic alumini alumini composite air duct i ʻoi aku ma mua o 3 mau manawa ma mua o ka duct air kuʻuna.Eia kekahi, hiki i ka 60% ~ 80% ka hoʻohana hou ʻana o ka phenolic aluminum foil composite air duct, ʻoiai ʻaʻole hiki ke hoʻohana hou ʻia ka duct air kuʻuna.
5. E ho'ēmi i ke kiʻekiʻe o ka papahele
Pono ka ʻauwaʻa ea kuʻuna i ke kūkulu ʻana i ka papa insulation ma ka pūnaewele, no laila pono ia i kahi kiʻekiʻe o ke kūkulu ʻana, kahi e waiho ai i nā koi hou no ke kiʻekiʻe o ka papahele o ka hale.ʻAʻole pono ke kūkulu ʻia ʻana o ka insulation ma ka pūnaewele, no laila ʻaʻole pono e mālama i kahi wahi kūkulu, hiki ke hoʻemi i ke kiʻekiʻe o ka papahele o ka hale.
