Pamene wononga firiji unit wayamba, chinthu choyamba kudziwa ngati firiji dongosolo ntchito bwinobwino. Zotsatirazi ndizofotokozera mwachidule zomwe zili ndi zizindikiro zogwirira ntchito bwino, ndipo zotsatirazi ndizongowona:
Madzi ozizira a condenser ayenera kukhala okwanira, kuthamanga kwa madzi kuyenera kukhala pamwamba pa 0.12MPa, ndipo kutentha kwa madzi sikuyenera kukhala kwakukulu.
Pamagawo a firiji wononga, kuwerengera kwa mphamvu ya mpope wamafuta kuyenera kukhala 0.15 ~ 0.3MPa kuposa kuthamanga kwa mpweya.
Mulimonse momwe zingakhalire, kutentha kwamafuta sikuyenera kupitirira 70°C pa firiji ya fluorine ndi 65°C m’firiji ya ammonia, ndipo kucheperako kusakhale pansi pa 30°C. Pansi pazikhalidwe zogwirira ntchito, mafuta opaka sayenera kutulutsa thovu (kupatula mafiriji a fluorine).
Refrigeration unit kutulutsa kutentha. Ammonia ndi R22 sadutsa 135 ° C, ndipo ngati kutentha kwa mpweya wotuluka kumakwera kwambiri, kudzakhala kochepa kwambiri poyerekeza ndi kutentha kwa mafuta a firiji (160 ° C), omwe si abwino kwa zipangizo. Choncho, poyang'ana ntchito, kutentha kwa mpweya sikuyenera kukhala kwakukulu, ndipo ngati kuli kwakukulu, kuyenera kuyimitsidwa kuti mudziwe chifukwa chake.
Mlingo wa condensing kuthamanga. Zimatsimikiziridwa makamaka molingana ndi gwero la madzi, kapangidwe ka condenser ndi refrigerant yogwiritsidwa ntchito. Mlingo wamadzimadzi wa posungira sudzakhala wotsika kuposa gawo limodzi mwa magawo atatu a chizindikiro chamadzimadzi, ndipo mulingo wamafuta wa crankcase sudzakhala wotsika kuposa mzere wopingasa pakati pa zenera la chizindikiro.
Chitoliro chobwezera mafuta chodziwikiratu cha olekanitsa mafuta a fluorine ndichabwinobwino kukakhala kozizira komanso kotentha, ndipo kuzizira ndi kutentha kumakhala pafupifupi ola limodzi. Pasakhale kusiyana kodziwikiratu kutentha kusanachitike komanso pambuyo pa fyuluta ya payipi yamadzimadzi. Pasakhale chisanu, apo ayi chidzatsekedwa. Firiji ya fluorine iyenera kukhala yozizira pambali yathyathyathya ndi yotentha kumbali youma. Malumikizidwe a fluorine system sayenera kutulutsa mafuta, zomwe zikutanthauza kuti fluorine kutuluka.
Mukakhudza condenser yopingasa panthawi yogwira ntchito, kumtunda kumayenera kutenthedwa ndipo kumunsi kukhale kozizira. Pamphambano ya ozizira ndi otentha ndi refrigerant madzi mlingo. Cholekanitsa mafuta chimakhalanso chotentha kumtunda, ndipo kumunsi sikutentha kwambiri. Valve yachitetezo kapena valavu yodutsa m'firiji iyenera kumva kuziziritsa kumapeto kwapakatikati, ngati sikuli kozizira, kumatanthauza kutsika kwamphamvu komanso kutsika kwa mpweya.
Panthawi yogwira ntchito, kuthamanga kwa nthunzi kuyenera kukhala kofanana ndi kuthamanga kwa mpweya, ndipo kuthamanga kwa mpweya kumapeto kwapamwamba kuyenera kukhala kofanana ndi kuthamanga kwa mpweya ndi kuthamanga kwa wolandira madzi. Ngati sichoncho, ndi zachilendo.
Pansi pa madzi ena othamanga, payenera kukhala kusiyana kwa kutentha pakati pa malo olowera ndi kutuluka kwa madzi ozizira. Ngati palibe kusiyana kwa kutentha kapena kusiyana pang'ono kwa kutentha, zikutanthauza kuti kutentha kwa kutentha kwa zipangizo zosinthira kutentha kumakhala kodetsedwa ndipo kumayenera kutsekedwa kuti kuyeretsedwe.
Firiji yokhayo iyenera kutsekedwa ndipo sikuyenera kutayira mufiriji ndi mafuta opaka mafuta. Pakuti kutsinde chisindikizo, pamene muyezo kuzirala mphamvu ndi 12.6 × 1000 kJ/h, kutsinde chisindikizo amaloledwa ndi pang'ono kutayikira mafuta, ndi firiji ndi muyezo kuzirala mphamvu> 12.6 × 1000 kJ/h saloledwa kukhala zosaposa 10 madontho a kutayikira mafuta, pa ola limodzi furiji refrigenon sikuyenera kukhala ndi madontho osapitirira 10 a mafuta a phenomenon. mafuta akutuluka.
Kutentha kwa chisindikizo cha shaft ndi kunyamula firiji sikuyenera kupitirira 70 ° C.
Frost kapena mame pa valavu yokulitsa ndi yofanana, koma chisanu chakuda sichiyenera kuwonekera polowera.
