Izinga lokushisa eliphansi.I-Absorption Chiller

Incazelo evamile:

Isimiso sokusebenzaUkuhwamuka koketshezi kuyinqubo yokushintsha kwesigaba kanye nokumunca ukushisa.Ingcindezi ephansi, ukuhwamuka okuphansi.isibonelo, ngaphansi kokucindezela komkhathi owodwa, izinga lokushisa lokuhwamuka kwamanzi liyi-100°C, futhi ku-0.00891 ukucindezela komkhathi, izinga lokushisa lokuhwamuka kwamanzi lizokwehla liye ku-5°C.Uma indawo enengcindezi ephansi ingasungulwa futhi amanzi asetshenziswe njengendlela yokuhwamuka, amanzi aphansi okushisa anezinga lokushisa lokugcwala elihambisana nokucindezela kwamanje kungatholakala.Uma amanzi aketshezi anganikezwa ngokuqhubekayo, futhi ukucindezela okuphansi kungagcinwa ngokuzinzile, amanzi aphansi okushisa okushisa adingekayo anganikezwa ngokuqhubekayo.I-LiBr yokumunca i-chiller, kuye ngezici zesisombululo se-LiBr, ithatha ukushisa kwesitimu, igesi, amanzi ashisayo neminye imidiya njengomthombo wokushayela, futhi ibona ukuhwamuka, ukumuncwa, ukufingqa kwamanzi esiqandisini kanye nenqubo yokukhiqiza isixazululo emjikelezweni wemishini ye-vacuum, ukuze inqubo yokuhwamuka kwezinga lokushisa eliphansi lamanzi ayisiqandisi iqhubeke.Lokho kusho ukuthi umsebenzi wokuhlinzeka ngokuqhubekayo ngamanzi abandayo aphansi okushisa ashayelwa umthombo wokushisa ungenziwa.

Okunamathiselwe ngezansi iphrofayili yenkampani yethu yakamuva.

Umdwebo wokugeleza

Umgomo wokusebenza wezinga lokushisa eliphansi.i-absorption chiller iboniswe ku-Fig. 3.2-1.
Umhwamuko oyisiqandisi okhiqizwe ujeneretha upholiswa phansi ku-condenser ngendlela yamanzi ayisiqandisi, abese ehanjiswa ngeshubhu le-U-shape epanini lokuconsa le-evaporator.Imunca ukushisa kwamanzi abandayo futhi yehlise izinga lokushisa layo ukuze ibeke inani, bese amanzi ayisiqandisi ehwamuka abe umhwamuko futhi angene ku-absorber.Ngemva kokumunca umhwamuko, isixazululo esigxilile kusinqamuleli siba isixazululo esihlanjululwe futhi sikhiphe ukushisa okumunca, okuthathwa ngamanzi apholisayo ukuze kugcinwe ikhono lokumunca lesisombululo.

Isixazululo esihlanjululwe esikhiqizwe i-absorber sihanjiswa ngepompo yesisombululo kumshini wokushisa, lapho sishiswa khona bese singena ku-generator.Ku-generator, isixazululo esihlanjululwe sishiswa ngamanzi ashisayo njengomthombo wokushisa (ogeleza ngaphakathi kwe-tube) endaweni yokubilisa futhi ukhiqize umhwamuko wesiqandisi.Phakathi naleso sikhathi, isixazululo esihlanjululwe sigxilwe kwisisombululo esigxilile, esiza ku-absorber ukuze siphinde inqubo yokuhamba ngebhayisikili eqhubekayo njengenhla.Amanzi okupholisa asetshenziselwa ukunciphisa izinga lokushisa eliphakathi nendawo ku-absorber kanye ne-condenser.Ngemva kokushisisa, ixhunywa kusistimu yombhoshongo wokupholisa bese ibuyiselwa kuyunithi ukuze isatshalaliswe ngemva kokupholisa.

Lesi sikhohlisi sokumunca esithengiswayo sisebenza kahle ngokusebenzisa amanzi okupholisa ukuze kugcinwe izinga lokushisa elilungile.Ukwengeza, i-chiller yokumunca ethengiswayo idizayinelwe ukuhlanganisa ngaphandle komthungo nezinhlelo ezikhona zombhoshongo wokupholisa.Okokugcina, le chiller yokumunca ethengiswayo iqinisekisa ukusebenza okuthembekile ngokusebenzisa inqubo yokugibela ibhayisikili eqhubekayo.

IZINTO EZIYINHLOKO NEMISEBENZI

Izinga lokushisa eliphansi.i-absorption chiller yenziwe ngokuyinhloko ngamadivayisi okushintshanisa ukushisa (ijeneretha, i-condenser, i-evaporator, i-absorber, i-heat exchanger, njalonjalo), idivayisi yokuhlanza okuzenzakalelayo, ipompo ye-vacuum, iphampu yesisombululo, ipompo yesiqandisi, i-valve ye-3-way motor kanye nekhabhinethi kagesi.Le chiller yokumunca ethengiswayo idizayinelwe ngezici zekhwalithi ephezulu ukuze kuqinisekiswe ukusebenza kahle.Ukwengeza, i-chiller yokumunca ethengiswayo ihlanganisa izici ezithuthukisiwe njengedivayisi yokuhlanza okuzenzakalelayo kanye nephampu ye-vacuum.I-chiller yokumunca ethengiswayo ibuye ifakwe i-valve ye-3-way motor kanye nekhabhinethi kagesi yokulawula okuthuthukisiwe nokuthembeka.

Cha.	Igama	Umsebenzi
1	Ijeneretha	Igxilisa isixazululo esihlanjululwe kusuka kusishintshi sokushisa sibe yisisombululo esigxilile sisebenzisa amanzi ashisayo noma isitimu njengesisetshenziswa.Khonamanjalo, umhwamuko wesiqandisi uyakhiqizwa futhi ulethwe ku-condenser, futhi ukugeleza kwesisombululo esigxilile kusidonsa.Isimo sokuklama: Ukucindezela okuphelele: ≈39.28mmHgSolution temp.: ≈80.27℃
2	I-Condenser	Ihlanganisa umhwamuko ophuma kujeneretha uwufake emanzini esiqandisi.Ukushisa okukhiqizwa ngesikhathi sokujiya kususwa amanzi okupholisa.Idiski yokuphuka ifakwa endaweni yokukhipha amanzi efrijini ye-condenser, izosebenza ngokuzenzakalelayo lapho umfutho weyunithi uphezulu ngendlela engavamile, ukuvikela iyunithi ekucindezelweni ngokweqile.Isimo sokuklama: Ukucindezela okuphelele ≈39.28mmHg
3	I-Evaporator	Ipholisa amanzi abandayo ngesidingo sokupholisa ngamanzi ayisiqandisi ahwamukile njengendawo ephakathi.Isimo sokudizayina: Ukucindezela okuphelele: ≈4.34mmHg
4	I-Absorber	Isixazululo esigxilile kusishunisi simunca umhwamuko oyisiqandisi olethwa ku-evaporator futhi amanzi okupholisa asuse ukushisa okumunca.
5	Isishintshi sokushisa	Isebenzisa kabusha ukushisa kwesisombululo esigxilile kujeneretha, ngaleyo ndlela ithuthukise i-coefficient ye-thermodynamic yesistimu.
6	Hlanza ngokuzenzakalela idivayisi	La madivayisi womabili ahlangana enze isistimu yokuhlanza umoya empompa umoya ongajiki kuyunithi, eqinisekisa ukusebenza kweyunithi futhi yandise impilo yesevisi.
7	Iphampu ye-vacuum
8	Iphampu yesiqandisi	Isetshenziselwa ukuletha kanye nokufafaza amanzi ayisiqandisi ngokulinganayo kunqwaba yeshubhu ehambisa ukushisa ye-evaporator.
9	Iphampu ye-generator	Ukuletha isixazululo generator, waqaphela kwegazi elingaphakathi unit.
10	Iphampu ye-absorber	Ukuletha isixazululo ku-absorber, waqaphela ukujikeleza kwangaphakathi kuyunithi.
11	I-valve yokudlula efrijini	Lawula ukuminyana kwamanzi esiqandisini ku-evaporator futhi ukhiphe amanzi anesiqandisi ngesikhathi sokuvalwa kweyunithi.
12	Isixazululo se-bypass valve	Lawula ukuminyana kwamanzi esiqandisini ku-evaporator
13	Imitha yokuminyana	Gada ukuminyana kwamanzi esiqandisini
14	3-indlela motor valve	Lawula noma nqamula okokufaka kwamanzi omthombo wokushisa
15	Ikhabhinethi yokulawula	Okokulawula ukusebenza kweyunithi
