Mafuta a Ester opangira firiji compressor
Mafuta a Ester opangira firiji compressor
Neopenyl saturated polyols ndi mafuta oyambira omwe amasungunuka ndi firiji ya HFC.
Ndioyenera kugwiritsidwa ntchito pobwezera, mtundu wa gyro ndi kugudubuza mafiriji compressor a R-134A, R-407C ndi R-410A.
Ili ndi kukhazikika kwamafuta, kukhazikika kwa hydrolysis, kutsika kwa evaporation komanso chizolowezi chotsika kwambiri cha coke, ndi zina zambiri.
Mapangidwe osiyana siyana amakwaniritsa zofunikira za miscibility yoyenera ya mafiriji osiyanasiyana.

Mafuta oyambira a HCFC refrigerants
Zogulitsa zomwe zili patsamba lotsatirali ndizoyenera mafiriji a HCFC.
Zogulitsa zimakhala ndi index yayikulu ya viscosity ndipo mafuta abwino amatha kupititsa patsogolo mphamvu zamagetsi.
Kusinthasintha kwabwino kwa kutentha kochepa komanso kusasunthika pang'ono kumalimbikitsa ma screw compressor ndi ma feed.
