Monga mainjiniya waluso yemwe wagwirapo ntchito mufiriji, vuto lovuta kwambiri liyenera kukhala vuto lobwezeretsa mafuta pamakina. Pamene dongosolo likuyenda bwino, mafuta ochepa adzapitiriza kuchoka pa compressor ndi mpweya wotulutsa mpweya. Pamene makina opangira magetsi apangidwa bwino, mafutawo adzabwerera ku compressor, ndipo compressor ikhoza kutenthedwa bwino; ngati pali mafuta ochulukirapo m'dongosolo, amakhudza kwambiri mphamvu ya condenser ndi evaporator; mafuta ochepa kubwerera ku kompresa kuposa kusiya kompresa, pamapeto pake kuwononga kompresa; kuwonjezera mafuta a compressor, amangosunga mafuta kwakanthawi kochepa; kuwongolera kokha kolondola Pokhapokha mwa kupanga, dongosololi likhoza kukhala ndi mafuta abwino, ndiyeno ntchito yotetezeka ya dongosolo ingapezeke.
Choyamba. Mapangidwe a payipi yoyamwa
1. Paipi yoyamwa yopingasa iyenera kukhala yotsetsereka kuposa 0.5% motsatira njira ya gasi wa refrigerant;
2. Gawo la mtanda la payipi yopingasa yopingasa liyenera kuonetsetsa kuti mpweya wotuluka ndi wosachepera 3.6m/s;
3. Mu payipi yowongoka yowongoka, kuchuluka kwa gasi kuyenera kutsimikiziridwa osachepera 7.6-12m/s;
4. Kuthamanga kwa mpweya wochuluka kuposa 12m / s sikungathe kusintha kwambiri kubwerera kwa mafuta, zomwe zidzatulutse phokoso lalikulu ndikupangitsa kutsika kwapakati pa mzere woyamwa;
5. Pansi pa mzere uliwonse woyamwa woyima, mafuta obwerera ngati U ayenera kukhazikitsidwa;
6. Ngati kutalika kwa mzere woyamwa woyima kupitilira 5m, mafuta obwera ngati U ayenera kukhazikitsidwa pa 5m iliyonse yowonjezera;
7. Utali wopindika wobwerera wa U-wofanana ndi U uyenera kukhala waufupi momwe ungathere kuti tipewe kudzikundikira mafuta ochulukirapo;
Chachiwiri, kamangidwe ka mapaipi a evaporator
1. Ngati makinawo sagwiritsa ntchito njira yopulumutsira, msampha wofanana ndi U uyenera kukhazikitsidwa potuluka pa evaporator iliyonse. Kuletsa refrigerant yamadzimadzi kuti isalowe mu kompresa pansi pa mphamvu yokoka panthawi yotseka;
2. Pamene chitoliro chokwera choyamwa chikugwirizanitsidwa ndi evaporator, payenera kukhala chitoliro chopingasa ndi kupindika pakati, kuti sensa ya kutentha ikhazikike molimba mtima; kuteteza valavu yowonjezera kuti isagwire bwino ntchito.
Chachitatu, Mapangidwe a chitoliro cha utsi
Pamene condenser imayikidwa pamwamba kuposa compressor, U-bend imafunika polowera kwa condenser kuteteza mafuta kuti asabwererenso kumbali ya kukhetsa kwa compressor panthawi yotseka, komanso kumathandiza kupewa firiji yamadzimadzi kuti isatuluke kuchokera ku condenser. bwererani ku compressor.
Chachinayi, kapangidwe ka mapaipi amadzimadzi
1. Paipi yamadzimadzi nthawi zambiri ilibe zoletsa zapadera pakuyenda kwa refrigerant. Pamene valve solenoid imagwiritsidwa ntchito, kuthamanga kwa firiji kuyenera kukhala kochepa kuposa 1.5m / s;
2. Onetsetsani kuti firiji yomwe imalowa mu valve yowonjezera ndi madzi osungunuka;
3. Pamene mphamvu ya refrigerant yamadzimadzi itsika mpaka kukhutitsidwa kwake, gawo lina la firiji lidzawala mu gasi.
