1. Tiyenera kusiyanitsa ngati mphamvu yogwira ntchito ya compressor firiji ndi yolimba.Ngati AC contactor chikugwirizana ndi kompresa firiji si kukoka mu, ndi kusintha mphamvu kotunga mkulu ndi otsika kutentha mayeso bokosi sangathe zochokera izi.Palinso ngati chingwe cha kompresa firiji cholumikizidwa ku bokosi lapamwamba komanso lotsika loyesa kutentha kwasweka kapena osalumikizidwa.Zipinda zina zoyezera kutentha kwapamwamba komanso zotsika zimakhalabe ndi zolakwika zina zazifupi panthawi yonse yoyendera.Ndiye kusiyanitsa ngati oveteredwa opaleshoni voteji akukwaniritsa zofunika.
2. Ndikofunikira kuti akatswiri asiyanitse mlingo wamakono wa compressor firiji mu chipinda choyesera chapamwamba ndi chotsika.Magawo onse apano akuyenera kuvotera mphamvu ya compressor ya firiji isanagwire ntchito moyenera.Ngati voteji yogwira ntchito ndi yachilendo, kuchuluka kwamakono sikunatchulidwe , Ndiye amasonyeza kusowa kwa refrigerant.
3. Yang'anani ngati chotenthetsera chotenthetsera chapamwamba komanso chotsika choyesa bokosi chikugwira ntchito bwino.Pansi pa ntchito, ma frequency amphepo ayenera kukhala okhazikika, mphepo iyenera kukhala yofanana ndi chitoliro champhepo chiyenera kukhala cholondola.Palinso njira yopumira kutentha kwa chitoliro cha mpweya wa refrigeration compressor.Kutentha kwabwino kwa chipinda choyesera chapamwamba ndi chotsika ndi chokwera kuposa kutentha kwanthawi zonse, monga momwe kutentha kwa mpweya wa kunja kwa mpweya wapakati kumakhala kokwera kwambiri.Onani ngati makina ozungulira a centrifugal m'chipindamo akugwira ntchito bwino.Ngati sichikugwira ntchito pambuyo poyaka, mpweya wozizira sungathe kusuntha bwinobwino, kotero kuti kutentha sikungachepetse.
