← TechnologyWhich outcome occurs when a refrigeration system uses a ternary azeotropic refrigerant bled into atmosphere during repair?
A)Fractionation leading to altered composition✓
B)Oil thickening from refrigerant stripping
C)Corrosion from moisture absorption
D)System overpressure from gas expansion
💡 Explanation
When a ternary azeotropic refrigerant blends into the atmosphere, fractionation occurs because the components have slightly different boiling points causing it to evaporate unevenly, therefore the composition changes because the most volatile evaporates first instead of others which would require the refrigerant remaining sealed.
