Pali njira ziwiri zobwezeretsera mafuta a kompresa: imodzi ndi kubweza mafuta olekanitsa mafuta, inayo ndi kubweza mafuta a chitoliro chobwezeretsera.
Cholekanitsa mafuta chomwe chimayikidwa mu mzere wa utsi wa compressor, nthawi zambiri chimatha kulekanitsidwa ndi 50-95% ya mafuta omwe akuyenda, kubwerera ku zotsatira za mafuta ndizabwino, mwachangu, zimachepetsa kwambiri kuchuluka kwa mafuta omwe amalowa mu payipi ya dongosolo, motero zimawonjezera nthawi yogwira ntchito popanda kubweza mafuta.
Kuyika mapaipi makamaka makina osungiramo ozizira kwa nthawi yayitali, makina odzaza ndi ayezi ndi zida zowumitsa zozizira kutentha kochepa, ndi zina zotero, pambuyo poyatsa kwa mphindi zoposa khumi kapena ngakhale mphindi makumi angapo mafuta kapena mafuta atabwerera ku zinthu zochepa si zachilendo, makina osapangidwa bwino adzakhala otsika kwambiri ndipo vuto lidzatsekedwa. Kukhazikitsa makina osungira mafuta ogwiritsidwa ntchito bwino kwambiri kumatha kuwonjezera nthawi yogwirira ntchito ya compressor popanda mafuta, kuti compressor idutse bwino mu gawo lamavuto la mafuta osabwerera pambuyo poyatsa. Mafuta odzola omwe sanalekanitsidwe adzalowa mu makinawo ndikuyenda ndi refrigerant mu chubu, ndikupanga kuzungulira kwa mafuta. Mafuta odzola amalowa mu evaporator.
Kumbali imodzi, chifukwa cha kusungunuka kochepa kwa kutentha, gawo la mafuta opaka kuchokera ku refrigerant limalekanitsidwa; kumbali ina, kutentha kumakhala kochepa, mafuta opaka olekanitsidwa ndi osavuta kumamatira kukhoma lamkati la chubu, ndipo kuyenda kumakhala kovuta. Kutentha kotsika kwa evaporation, kumakhala kovuta kubwereranso ku mafuta. Izi zimafuna kapangidwe ka evaporation payipi ndi kubwezeretsanso payipi ya mpweya ndi kapangidwe kake kuyenera kukhala koyenera kuti mafuta abwerere, njira yodziwika bwino ndikugwiritsa ntchito kapangidwe ka payipi yotsika, ndikuwonetsetsa kuti mpweya ukuyenda bwino.
