← TechnologyWhich outcome occurs when a binary refrigerant mixture leaks from a refrigeration system?
A)Glide temperature increases near saturation
B)System COP degrades due to composition shift✓
C)Compressor discharge pressure becomes erratic
D)Oil return to the compressor is inhibited
💡 Explanation
When a binary refrigerant leaks, fractional distillation occurs during phase change because components escape non-azeotropically, resulting in composition drift and thus a reduction in coefficient of performance. Therefore COP degrades, rather than consistent temperature changes, pressure fluctuations, or oil return problems which have different origins.
