Kufotokozera mfundo ya chowumitsira ozizira
Mogwirizana ndi chithunzi pansipa, tiyeni tiyende mu ndondomeko ya chowumitsira ozizira.Njirayi imagawidwa m'magawo awiri, omwe amatsogolera bwalo la buluu (gasi kuti aumidwe) ndi bwalo lofiira (wothandizira).Kuti muwone mosavuta, ndinayika njira za bwalo la buluu ndi bwalo lofiira pamwamba ndi pansi pa chithunzicho.
(1) Mpweya womwe umafunika kuumitsidwa ndi kunyamula nthunzi wambiri wamadzi umalowa mu precooler kuchokera polowera (1)
(2) Ndiye chinyontho chotentha kwambiri chimalowa mu evaporator yapansi, ndipo mpweya umazungulira kunja kwa chubu chosinthira kutentha kuti usinthe kutentha ndi chotsitsa chotsika kwambiri cha kutentha mkati mwa chubu chosinthira kutentha, potero kuchepetsa kutentha kwa mpweya.
(3) Chinyezi chozizira chimalowa m'malo olekanitsa madzi a gasi, ndipo cholekanitsa chokhala ndi ukadaulo wapamwamba kwambiri chimachotsa 99.9% ya chinyezi ndikuchitulutsa kudzera mu kukhetsa kwadzidzidzi.
(4) Mpweya wowuma umalowa mu pre-cooler kuchokera ku (4), ndipo usanayambe kuziziritsa chinyezi chapamwamba chomwe changolowa kumene mu pre-cooler kuchokera (1), ndipo nthawi yomweyo chimawonjezera kutentha kwake, ndipo mpweya kutentha kutentha kumayamba kuuma, ndipo pamapeto pake amachoka kumanja kwa precooler kuti agwiritse ntchito
(1) Condensant (yoziziritsira) imayambira potulutsa kompresa
(2) Kupyolera mu valavu yodutsa, gawo laling'ono la condensing agent limatumizidwa ku cholowera (5) kupyolera mu valavu yodutsa, ndikulowa mwachindunji mkati mwa evaporator, ndipo ena onse a condensing agent akupitiriza kupita patsogolo.
(3) The condensing agent yomwe ikupitiriza kupita patsogolo idzadutsa mu condenser ndi kubatizidwa ndi fani kuti izizirenso.
(4) Kenako, condensing agent amafika pa valavu yokulirapo yomaliza yozizirira kwambiri
(5) Pambuyo pa condensing agent yomwe yakhala itakhazikika kwambiri ndi valavu yowonjezera imasakanizidwa ndi mpweya wotentha kwambiri womwe umachokera ku bypass valve (kuteteza kuzizira), umalowa mu chubu chosinthira kutentha mu evaporator.
(6) Ntchito ya condensing agent mu chubu chosinthira kutentha ndi kuziziritsa kutentha kwakukulu ndi chinyezi choperekedwa ndi wogwiritsa ntchito, ndikutumiza kunja komweko (6)
(7) The condensing agent amabwerera ku kompresa kukonzekera ulendo wotsatira wa condensation ntchito
