Which risk increases within a refrigeration cycle approaching its adiabatic expansion limit?

💡 Explanation

Compressor oil thermal decomposition risk increases because high compressor output temperatures accelerate oil breakdown via pyrolysis inside the compressor; therefore, oil degradation will occur, rather than the given issues from other components in stable circumstances.
