I-manifold, eyaziwa nangokuthi i-distribution manifold, iyingxenye eyinhloko yesistimu yokushisa ngaphansi komhlaba. Ikakhulu ixhuma amapayipi amakhulu okuphakela nokubuyisela amanzi futhi ihlukanisa amanzi ashisayo kuzo zonke izixhumanisi zokushisa.

Isakhiwo Esiyisisekelo Nezisebenzi: I-manifold iqukethe iphayiphi elikhulu lokusabalalisa (elixhunywe nephayiphi lokuhlinzeka) kanye nephayiphi elikhulu lokuqoqwa (elixhunywe nephayiphi lokubuyisela). Ipayiphi elikhulu lokusabalalisa lisabalalisa amanzi ashisayo kumapayiphi okushisa aphansi egumbini ngalinye, kanti iphayi elikhulu lokuqoqwa liqoqe amanzi abuyayo. Imisebenzi yayo eyinhloko ifaka phakathi ukucindezela, ukunciphisa ucindezelo, ukuzinza kocindezelo, nokusabalalisa ukuhamba ukuze kuqinisekiswe ukuhamba kwamahhala kwamanzi ashisayo.

Izinsiza ngokuvamile zifaka ama-valve ebhola, ama-valve okulawula ukuhamba, izikhala zomoya, kanye nezihlungi, ezisetshenziselwa ukulawula ukuhamba kwamanzi, ukususa umoya, nokuhlungela okungcolile.

Ukuhlukaniswa Nezici: Ngokusekelwe emsebenzini nasestructure, ama-manifolds angahlukaniswa abe izinhlobo ezintathu:

Uhlobo Oluyisisekelo: Luhlinzekwa nge-valve yebhola kanye nesikhala somoya esenziwa ngesandla, sinikeza kuphela ukulawula okuyisisekelo kokuvula/nokuvala ngaphandle kokulawula ukuhamba.

Uhlobo Olujwayelekile: Luthuthukiswe nge-valve yokulawula ukuhamba kanye ne-automatic air vent, evumela ukulungiswa okunembile kwesilinganiso sokuhamba kuzo zonke izixhumanisi; amamodeli athile asekelwa ukulungiswa okuhlakaniphile. **Uhlobo Olusebenza:** Luhlanganisa ukuboniswa kokushisa/nengcindezi, ukuhlanganiswa okuzenzakalelayo, ukukala ukushisa, ukulawula kokushisa okwenziwe ngezifunda, nezici zokulawula kude, ezifanele izinhlelo ezisezingeni eliphezulu.

Ngaphezu kwalokho, ngokusekelwe ekusebenzeni kokwakhiwa, ihlukaniswe kube nguMphakathi waseKorea kanye noMphakathi waseYurophu: uMphakathi waseKorea unokwakheka okulula nezindleko eziphansi, ezifanele ukushisa okuyisisekelo ngaphansi komhlaba; uMphakathi waseYurophu unezici eziphelele kakhulu kanye nezinga eliphezulu lokuhlakanipha, ngokuvamile lisetshenziswa ezindlini ezisezingeni eliphezulu noma ezinhlelweni zokushisa ezizimele.

**Izidingo Zempahla Nokufakwa:** Ukuze kugwenywe ukuvuvukala, i-manifold ivamise ukwenziwa ngezinto ezivumelana nokuvuvukala ezifana ne-copper ehlanzekile noma insimbi engagqwali; insimbi ye-cast kufanele igwenywe. 1. Ngesikhathi sokufakwa, kufanele ibekwe kahle emathafeni noma ebhokisini elikhethekile (njengasekhishini). I-manifold kufanele ibe okungenani ama-30 cm phezulu komhlaba. Kufanele kufakwe ifilitha ekugcineni. Uhlelo lokuxhuma luwukuthi: ipayipi lokuhlinzeka → ivali lokumisa → ifilitha → i-manifold → ipayipi lokushisa ngaphansi komhlaba → ikholi → ipayipi lokubuyisela.

**Ukusetshenziswa Nokmaintenance:** Ngaphambi kokushisa unyaka nonyaka, ivali ye-air vent kufanele ivulwe ukuze kukhishwe umoya emaphaketheni. I-filter kufanele ihlanzwe njalo ukuze kugcinwe amaphakethe ehlanzekile. Uma ingasetshenziswa isikhathi eside, ivolumu yamanzi ehambayo ingancishiswa. Ebusika, uma ukushisa kungasetshenziswa, amanzi emaphaketheni kufanele aphume ukuze kugwenywe ukujula nokuphuka. ‌
