I-Chiller, i-Cooling Tower kunye ne-Air Handling Unit isebenza njani kunye ukubonelela nge-air conditioning (HVAC) kwisakhiwo.Kweli nqaku siza kugubungela esi sihloko ukuqonda iziseko zeHVAC esembindini yesityalo.

Indlela yokupholisa inqaba yokupholisa kunye ne-AHU isebenza kunye

Amalungu enkqubo engundoqo yesityalo esisembindini sokupholisa ngala:

• Chiller
• IYunithi yokuphatha umoya (AHU)
• Inqaba yokupholisa
• Iimpompo

I-chiller iya kuhlala ibekwe kwindawo engaphantsi okanye phezu kophahla kwaye oku kuxhomekeke kuhlobo luni lwe-chiller olusetyenziswayo.Izibandisi eziphezulu eluphahleni ziqhele ukuba "zipholile emoyeni" ngelixa iindawo zokupholisa ezisezantsi zihlala "Amanzi apholisiwe" kodwa zombini zenza umsebenzi ofanayo wokuvelisa amanzi abandayo omoya opholileyo ngokususa ubushushu obungafunekiyo kwisakhiwo.Umahluko kuphela yindlela i-chiller elahla ngayo ukushisa okungafunekiyo.

Izibandisi zomoya ezipholileyo ziya kusebenzisa iifeni ukuvuthela umoya opholileyo we-ambient phezu kwecondenser yazo ukususa ubushushu kwinkqubo, olu hlobo alusebenzisi inqaba yokupholisa.Unokufunda malunga nale nkqubo kwaye ubukele isifundo sevidiyo ngokucofa apha.Kwintsalela yeli nqaku siza kujolisa kumanzi apholise i-chillers kunye neenqaba zokupholisa.

I-chiller yamanzi epholileyo ineesilinda ezimbini ezinkulu, enye ibizwa ngokuba yi-evaporator kwaye enye ibizwa ngokuba yi-condenser.

Amanzi abandayo:
I-evaporator ye-chiller kulapho "amanzi abandayo" enziwa khona.“Amanzi abandayo” ashiya i-evaporator malunga ne-6°C (42.8°F) aze atyhaleke ajikeleze isakhiwo ngempompo yamanzi ebandayo.Amanzi abandayo aqukuqela phezulu kumphakamo wesakhiwo ukuya kumgangatho ngamnye kwimibhobho eyaziwa ngokuba “zinyusi”.Le mibhobho yaziwa ngokuba zizinyusi kungakhathaliseki ukuba amanzi aya phezulu okanye ezantsi ngaphakathi kuyo.

Amanzi abandayo asusela kwizinyusi abe yimibhobho edayamitha emincinci eya kwiiyunithi zeekhoyili zeefeni (FCU's) kunye neeYunithi zokuPhathwa koMoya (AHU's) ukuze zibonelele ngokupholisa umoya.I-AHU kunye ne-FCU's ngokusisiseko ziibhokisi ezineefeni ezingaphakathi ezifunxa umoya kwisakhiwo kwaye ziwutyhale ngapha kobushushu okanye iikhoyili zokupholisa ukutshintsha ubushushu bomoya kwaye emva koko utyhale lo moya ubuyele ngaphandle kwisakhiwo.Amanzi abandayo angena kwi-AHU/FCU aze adlule kwikhoyili yokupholisa (uthotho lwemibhobho ebhityileyo) apho aya kutsala ubushushu bomoya ovuthuza ngapha nangapha.Amanzi abandayo ashushu kwaye umoya ovuthuza kuwo uyaphola.Xa amanzi abandayo eshiya ikhoyili yokupholisa ngoku azakuba shushu malunga ne-12°C (53.6°F).Amanzi afudumeleyo abandayo aphinde abuyele emva kwi-evaporator, ngokusebenzisa isikhuphukeli esibuyayo, kwaye nje ukuba ingene kwi-evaporator isibandisi siyakufunxa ubushushu obungafunekiyo kwaye siyise oku kwi-condenser.Amanzi abandayo aya kuthi emva koko ashiye epholile kwakhona, elungele ukujikeleza kwisakhiwo kwaye aqokelele ubushushu obungafunekiyo.Qaphela: amanzi abandayo abizwa ngokuba "ngamanzi abandayo" kungakhathaliseki ukuba afudumele okanye apholile.

Amanzi eCondenser:
I-condenser ye-chiller kulapho ubushushu obungafunwayo buqokelelwa khona ngaphambi kokuba buthunyelwe kwiinqaba zokupholisa.Isikhenkcisi sidlula phakathi kwe-evaporator kunye ne-condenser ukuhambisa bonke ubushushu obungafunekiyo.Enye i-loop yamanzi, eyaziwa ngokuba yi "condenser water", idlula kwi-loop phakathi kwe-condenser kunye nenqaba yokupholisa.Isikhenkcezisi siqokelela ubushushu kwilophu "yamanzi abandayo" kwi-evaporator kwaye ihambisa oku "kwi-condenser water" loop kwi-condenser.

I-condenser yamanzi ingena kwi-condenser malunga ne-27 ° C (80.6 ° F) kwaye iya kudlula, iqokelele ubushushu endleleni.Ngexesha lokushiya i-condenser iya kuba malunga ne-32 ° C (89.6 ° F).Amanzi e-condenser kunye nefriji ayixubani, zihlala zihlulwe ngodonga lombhobho, ubushushu budlulisa nje eludongeni.Emva kokuba amanzi e-condenser edlulile kwi-condenser kwaye athathe ubushushu obungafunekiyo, iya kukhwela kwiinqaba zokupholisa ukulahla obu bushushu kwaye ibuyisele ipholile ilungele ukuqokelela ubushushu obuninzi.

Inqaba yokupholisa:
Inqaba yokupholisa idla ngokubekwa phezu kophahla kwaye yindawo yokugqibela yobushushu obungafunekiyo kwisakhiwo.Inqaba yokupholisa iqulethe ifeni enkulu evuthela umoya kwiyunithi.Amanzi econdenser ampompelwa ukuya kwiinqaba zokupholisa aze atshizwe kumlambo womoya.Umoya opholileyo we-ambient uya kungena kwaye udibane ngqo nokutshizwa kwamanzi e-condenser (kwinqaba yokupholisa evulekileyo) oku kuya kuvumela ubushushu bamanzi e-condenser ukuba budlulele emoyeni kwaye lo moya uvuthelwe emoyeni.Amanzi econdenser emva koko aqokelele kwaye abuyele kwi-condenser ye-chiller elungele ukuqokelela ubushushu obuninzi.Jonga isifundo sethu esikhethekileyo kwiinqaba zokupholisa apha.
