Ubushushu obuphantsi.I-Absorption Chiller
Umgaqo osebenzayo weqondo lokushisa eliphantsi.i-absorption chiller iboniswe kwi-Fig. 3.2-1.
Umphunga wefriji owenziwe yijenereyitha upholiswa phantsi kwi-condenser ngendlela yamanzi efriji, ethi ke ihanjiswe nge-U-shape tube kwi-pan ye-drip ye-evaporator.Ifunxa ubushushu bamanzi abandayo kwaye ihlise ubushushu bayo kwixabiso lokubeka ixabiso, emva koko amanzi efriji aphuphuma abe ngumphunga kwaye angene kwi-absorber.Emva kokufunxa umphunga, isisombululo esigxininisiweyo kwi-absorption siba sisisombululo esixutywe kwaye sikhupha ubushushu bokufunxa, obuthatyathwa ngamanzi okupholisa ukugcina isakhono sokufunxa isisombululo.
Isisombululo esihlanjululweyo esiveliswe i-absorber sihanjiswa ngepompo yesisombululo kwi-heat exchanger, apho ishushu kwaye ingena kwi-generator.Kwi-generator, isisombululo esihlanjululweyo sifudumala ngamanzi ashushu njengomthombo wokushisa (ohamba ngaphakathi kwi-tube) ukuya kwindawo yokubilisa kwaye uvelise umphunga wefriji.Okwangoku, isisombululo esihlanjululweyo sigxininiswe kwisisombululo esigxininisiweyo, esiza kwi-absorber ukuphinda inkqubo eqhubekayo yokukhwela ibhayisikile njengasentla.Amanzi okupholisa asetyenziselwa ukunciphisa ubushushu obuphakathi kwi-absorber kunye ne-condenser.Emva kokufudunyezwa, idityaniswe kwinkqubo yokupholisa yenqaba kwaye ibuyiselwe kwiyunithi ukuze ijikelezwe emva kokupholisa.
Ubushushu obuphantsi.i-absorption chiller yenziwe ngokuyinhloko kwizixhobo zokutshintshiselana kobushushu (ijeneretha, i-condenser, i-evaporator, i-absorber, i-heat exchanger, njalo njalo), isixhobo sokucoca ngokuzenzekelayo, ipompo yokucoca, impompo yesisombululo, impompo yefriji, i-valve ye-3-way motor kunye nekhabhinethi yombane.
| Hayi. | Igama | Umsebenzi |
| 1 | Ijenereyitha | Igxininisa isisombululo esihlanjululweyo esivela kumtshintshi wokushisa kwisisombululo esigxininisiweyo usebenzisa amanzi ashushu okanye i-steam njengento ephakathi.Okwangoku, umphunga wefriji uyaveliswa kwaye uhanjiswe kwi-condenser, kunye nokuhamba kwesisombululo esigxininisiweyo kwi-absorber.Imeko yoyilo: Uxinzelelo olupheleleyo: ≈39.28mmHgSolution temp.: ≈80.27℃ |
| 2 | Icondenser | Idibanisa umphunga ophuma kwijeneretha ukuya kumanzi efriji.Ubushushu obuveliswayo ngexesha lokujiya buthathwa ngamanzi okupholisa.Idiski yokugqabhuka ifakwe kwindawo yokuphuma kwamanzi efriji yecondenser, iya kusebenza ngokuzenzekelayo xa uxinzelelo lweyunithi luphezulu ngokungaqhelekanga, ukukhusela iyunithi kwixinzelelo olungaphaya.Imeko yoyilo: Uxinzelelo olupheleleyo. ≈39.28mmHg |
| 3 | Umphunga | Ipholisa amanzi abandayo ukulungiselela imfuno yokupholisa ngamanzi efriji engumphunga njengendawo ephakathi.Imeko yoyilo: Uxinzelelo olupheleleyo: ≈4.34mmHg |
| 4 | Ufunxa | Isisombululo esigxininisiweyo kwisibambisi sifunxa umphunga ophuma kwisikhenkcezisi ophuma kwi-evaporator kwaye amanzi okupholisa ayabususa ubushushu bokufunxa. |
| 5 | Umtshintshi wobushushu | Ibuyisela kwakhona ubushushu besisombululo esigxininisiweyo kwijenereyitha, ngoko ke iphucula i-coefficient ye-thermodynamic yenkqubo. |
| 6 | Isixhobo sokucoca ngokuzenzekelayo | Ezi zixhobo zimbini zidibanisa ukwenza inkqubo yokucoca umoya empompa umoya ongagungqiyo kwiyunithi, iqinisekisa ukusebenza kweyunithi kwaye yandisa ubomi benkonzo. |
| 7 | Impompo yokufunxa | |
| 8 | Impompo yefriji | Isetyenziselwa ukuhambisa kunye nokutshiza amanzi efriji ngokulinganayo kwi-tube-conducting tube bundle ye-evaporator. |
| 9 | Impompo yejenereyitha | Hambisa isisombululo kwijenereyitha, yaqonda ukujikeleza kwangaphakathi kwiyunithi. |
| 10 | Impompo yokufunxa | Hambisa isisombululo kwi-absorber, yaqonda ukujikeleza kwangaphakathi kwiyunithi. |
| 11 | Ivalve yokudlula efrijini | Lawula ubuninzi bamanzi efriji kwi-evaporator kwaye ukhuphe amanzi efriji ngexesha lokuvalwa kweyunithi. |
| 12 | Ivalve yokudlula isisombululo | Ukulawula ubuninzi bamanzi efriji kwi-evaporator |
| 13 | Imitha yoxinzelelo | Ukubeka esweni ubuninzi bamanzi efriji |
| 14 | 3-indlela ivelufa motor | Lawula okanye ucime igalelo lamanzi kwimithombo yobushushu |
| 15 | Ikhabhinethi yokulawula | Kulawulo lweyunithi yokusebenza |
