PVC, ABS, kana CPVC Pipipu yekutsva Vira
Nzvimbo yegasi-inopiswa, iyo yakamanikidzwa-mhepo inoshandiswa kushandiswa kwesimbi, inowanzoendeswa mumudziyo wemagetsi, kuti inopisa magasi anopisa akaumbwa muimba yomoto. Asi mune mazuva ano ekugadzirwa kwepamusoro-soro, mafaira epurasitiki epamusoro (kazhinji PVC , ABS, kana CPVC ) inoshandiswa kuunza mweya, kupedza gasi, uye kutakura kukonzera kunokonzerwa nekupisa. Zvisinei, pane kushayikwa kwekunzwisisa nekuzvidavirira pamusoro pemitemo inogamuchirwa yekuvaka yezvinhu izvi zvekurota.
Chokutanga, ngatitarirei mhando dzakasiyana dzehuni dzinopinda munharaunda iyi.
Mhando dzeWeded Condensing Furnace Systems
Kune miviri miviri yekugadzirisa zvivako-maviri-pipe zvidzidzo zvinotenderera zvakananga, uye se-single-pipe systems dzisingatauri kutenderera.
Dzorera (two-pipe) system: Iviri-pombi inonyatsobuda yevhu inowanzoshandiswa mumapurisa ekuchenesa kumba. Inopa mhepo yakananga iyo inounza kunze kwemhepo kune kamuti yakavharidzirwa kamuri nemumwe pombi, apo imwe yechipiri pipipu inobudisa chisimbiso chekudzima gasi kunobva kunze kweimba yako. Mune zvakananga vent system, iwe unogona kuona nyore nyore mapaipi maviri achibuda nechemberi kweimba yako.
Nzira isina kutungamirirwa (single-pipe) system: Iyo imwe-pombi, isiri iyo yakananga yekushanda inoshandiswa apo pasina chidikanwi chaicho chekuparadzanisa kwemafirimu emhepo. Inopa pombi yemhepo yekubudisa gasi asi inoshandisa zvisingaverengeki (zvisati zvanyoroveswa kana kuti kupisa) mhepo kubva munzvimbo yakakomberedza vira romoto inopisa.
Aya mavhiri anowanzoiswa munzvimbo dzisina kukwana, dzakadai segaraji, crawlspace, pasi, kana nzvimbo yepamusoro, uko kunopisa mumhepo kwakakwanira zvakakwana kuti kugovera mabhuku anokwana emhepo inenge isina kupisa.
Sei Chigodo Chinopisa Chichida Inoda Kumbera yeCondensate?
Izvo zvinoshandiswa nemagetsi zvepamusoro-kukwanisa kugadzirisa tanini ine ruzivo rwakakosha uye zvinokonzera mvura inoshandiswa.
Nemhaka yekupisa kwakanyanya kupinza teknolojia inoshandiswa nevira rinokonzera moto, kupisa kunobudiswa kubva kune mafuta anokonzera kupisa kwemazuva mazhinji, kusvika apo moto unopisa gasi "wakanatswa" uye unogadziriswa. Iyo gasi inopera inopera kupisa kusvikira mvura inokonzera mvura ichidonha kubva muvira remoto inopisa, uye yakadzika-kutonhora flue gasiza kupukunyuka kubva pombi yepurasitiki yakasarudzwa, panzvimbo yekuendeswa kune chimbuzi. Iyo pombi ye condensate inowanzomhanyira kuchitsiko chakavhara kana imwe bhesheni yekubata.
Kupa kuronga kwakarurama kunokosha kune zvakakodzera, kushanda zvakanaka kwevira. Inopa mvura yakakwana yekodenate uye inobatsira kuchengetedza kuvimbika kwomweya wose kudya uye kupedza gasi rinowedzera. Kusungirirwa kusina kunaka kwechoto kunopisa kana kuti condensate system kunogona kutungamirira kuchibato chisina basa.
Nei Pombi Pombi?
Zviyo zvinokonzera moto zvinorongerwa seCATEGORY IV zvishandiso maererano nemashandiro emakambani, akawanikwa mune zvinyorwa zvakanyorwa seAnSI Z21.47 (CGA-2.3), iyo inoda kuti maitiro ekudzivirira ave akasimba nemvura uye akasimba. Ivira rinoshandisa rinopisa motokari motokari inokonzera gasi rinopisa kuburikidza nechokuita pombi, ichigadzira chimiro chakanaka chemhepo mumhepo.
Iko rinopisa rinokonzera gasi rinopisa rinoputika rine mvura uye carbon dioxide, iyo pamwe chete inoumba carbonic acid inokonzera kuora kwemvura. Sezvo zvakadaro, chete mapepa chaiwo eepurasitiki anorayirwa nevanopisa vira kuti vadziye uye vanokonzera mvura mukati mevira romoto.
Zvinokurudzirwa kuti kubhururuka kwepiping kunofanira kuitwa kubva kune mamwe marudzi ePVC (Poly-Vinyl Chloride), CPVC (Chlorinated Poly-Vinyl Chloride) uye ABS (Acrylonitrile-Butadiene-Styrene) pombi yepurasitiki, zvichienderana nevira remhepo rinotonhora kupisa gasi. Aya mapurasitiki akasiyana akasiyana-siyana kupisa kushanda kushanda: PVC ine yakaderera kusvika ku 140 ° F., CPVC ine yepamusoro pa194 ° F., uye ABS inowira pakati, pakushambidzika kwemashumiro e 160 ° F. Kuputsika kwepipe, zvakadai sokuputika kana kuputika, zvinogona kuitika kana kutonhora kwakachengeteka kupfuura izvi zvinoridzirwa kushanda kushanda.
Indasitiri Kusanganiswa NezveMitemo
Iyo International Fuel Gas Code inotaura muchitsauko 503.4.1.1 (IFGS) "Ipombi yepurasitiki uye zvigadziriswa zvinoshandiswa kushandisa midziyo zvinoshandiswa maererano nemirayiridziro emagetsi ekugadzira magetsi." Pano pane dambudziko. Kunyange zvazvo vashandisi mirayiridzo vachanyora kuti ndeapi mapiritsi anogamuchirwa pamiti yavo, vanoisiya iyo kusvika pakusungira makontrakta kuti aone kuti ipurasitiki ipi inoshandiswa.
Zvinoshamisa kuti, kunyange zvazvo kuvapo kwepurasitiki midzi yepurasitiki yakangofanana nekukwirira kwepamusoro-soro , vashandi vePVC havangakurudziri PVC iyi yekushanda. Uyewo hapana hurumende yeASTM yepombi yepurasitiki inoshandiswa sezvinovhenekera gesi inowedzera. Kunyangwe apo muiti wehuni anotaura nezvemahofisi ehurumende uye yakasarudzwa-yakadai seASTM D1785 yeHedheni 40 PVC pipe-iyo inowanikwa chete yekuisa pombi. Kutaura zvazviri, ASTM D1785 yakarongerwa Purogiramu ye40 (kushandiswa pakushongedza kupinza mabomba) inoti "Izvi zvinotsanangurwa zvePVC pipe hazvirevi zvinodikanwa zvepombi uye zvigadziri zvinoshandiswa kushandiswa kupisa magasi anopisa."
Nhamba uye Mazano
Kuvaka magwaro kumativi ose enyika uye munharaunda inoita sekutaridzika kune vashandi vevira kuti vatsanangure kuti mapepa epurasitiki angashandiswa sei semhepo inotonhorera yekutengesa nemishonga yavo. Zvimwe zvinorayirwa kunze, kunyange zvakadaro, ndiyo yekugadzira makontrakta uyo anozopedzisira agadzira pombi yepurasitiki yekushandisa.
Pasinei nokuvhiringidzika, tsika yakachengeteka ingaratidza kushandiswa kwePVC purogiramu makumi mana emapapiro emhepo inopisa mukati mevira uye CPVC yekudzima kwemafuta, zvichibva kune yakakwirira yebasa rekushanda. Nenzira iyo, inofanira kuva nechinetso nevira umo izvo zvinokonzera kupisa kwekuyerera kupfuurira kugadzirwa, iyo yekubudisa simba yevhu inenge inenge 40% yakawanda inokwanisa kukwanisa kupisa kupisa kusati yasvika pakona iyo inogona kukundikana.
