| Abstract: | The flock points when the interaction happened between the three kinds commercial full-closed refrigerator oils DRB/A32 with different distillation range and composition and R12 or R600a respectively were analyzed.The result indicated that R12 and R600a have different effects on the flock points of the refrigerator oils;By separating the refrigerator oil into different fractions,the effects of refrigerator oils with different distillation range,density,average molecular weight and group composition on the flock point were discussed.It is concluded that the flock point of the refrigerator oil lies on it′s composition and cold intermediary which is used on testing. |
