Monga mainjiniya waluso yemwe wagwira ntchito mu makina oziziritsira, vuto lalikulu liyenera kukhala vuto la kubweza mafuta mu makinawo. Makinawo akamagwira ntchito bwino, mafuta ochepa amapitiriza kusiya compressor ndi mpweya wotulutsa utsi. Pamene mapaipi a makinawo apangidwa bwino, mafutawo amabwerera ku compressor, ndipo compressor imatha kudzozedwa mokwanira; ngati pali mafuta ambiri mu makinawo, zimasokoneza magwiridwe antchito a condenser ndi evaporator; mafuta ochepa amabwerera ku compressor kuposa kusiya compressor, zomwe pamapeto pake zimawononga compressor; kudzaza mafuta mu compressor, kumasunga mafuta kwa kanthawi kochepa; mapaipi olondola okha Ndi kapangidwe kokha, makinawo amatha kukhala ndi mafuta abwino, kenako ntchito yotetezeka ya makinawo ingapezeke.
Choyamba. Kapangidwe ka payipi yoyamwa
1. Paipi yoyatsira mpweya yopingasa iyenera kukhala ndi malo otsetsereka opitirira 0.5% motsatira njira yoyendera mpweya wozizira;
2. Gawo lopingasa la payipi yoyatsira mpweya yopingasa liyenera kuonetsetsa kuti mpweya ukuyenda bwino osapitirira 3.6m/s;
3. Mu payipi yoyatsira mpweya yoyimirira, kuchuluka kwa mpweya kuyenera kutsimikizika osachepera 7.6-12m/s;
4. Kuthamanga kwa mpweya woposa 12m/s sikungathandize kwambiri kubweza mafuta, zomwe zingapangitse phokoso lalikulu ndikupangitsa kuti mphamvu ya mpweya itsike kwambiri mu chingwe chokokera mpweya;
5. Pansi pa mzere uliwonse woyimirira, mafuta obwezerezedwanso okhala ngati U ayenera kuyikidwa;
6. Ngati kutalika kwa mzere wokokera woyimirira kupitirira 5m, mafuta obwezerezedwanso okhala ngati U ayenera kukhazikitsidwa pa 5m iliyonse yowonjezera;
7. Kutalika kwa kupindika kwa mafuta kofanana ndi U kuyenera kukhala kochepa momwe kungathekere kuti mafuta asachuluke kwambiri;
Chachiwiri, kapangidwe ka payipi yoyatsira evaporator
1. Pamene dongosolo silikugwiritsa ntchito njira yotulutsira mpweya, msampha wooneka ngati U uyenera kuyikidwa pamalo otulukira mpweya uliwonse. Kuti mupewe kuti firiji yamadzimadzi isalowe mu compressor chifukwa cha mphamvu yokoka panthawi yotseka;
2. Pamene chitoliro chokwezera mpweya chokokera mpweya chalumikizidwa ku evaporator, payenera kukhala chitoliro chopingasa ndi kupindika pakati, kuti sensa ya kutentha ikhazikitsidwe molimba mtima; kuti valavu yokulitsa isagwire ntchito bwino.
Chachitatu, Kapangidwe ka chitoliro chotulutsa utsi
Pamene condenser yayikidwa pamwamba kuposa compressor, U-bend imafunika pamalo olowera a condenser kuti mafuta asabwerere kumbali yotulutsira compressor panthawi yotseka, komanso zimathandiza kuti refrigerant yamadzimadzi isatuluke kuchokera ku condenser.
Zinayi, kapangidwe ka mapaipi amadzimadzi
1. Paipi yamadzimadzi nthawi zambiri imakhala ndi zoletsa zapadera pa kuchuluka kwa madzi mufiriji. Mukagwiritsa ntchito valavu ya solenoid, kuchuluka kwa madzi mufiriji kuyenera kukhala kochepera 1.5m/s;
2. Onetsetsani kuti firiji yomwe ikulowa mu valavu yokulitsa ndi madzi ozizira pang'ono;
3. Pamene mphamvu ya madzi mufiriji yatsika kufika pa mphamvu yake yokwanira, gawo lina la firijiyo lidzasanduka mpweya.
