← ScienceWhich limitation arises when an ammonia-based absorption chiller operates far from equilibrium on its cycle?
A)Decreased coefficient of performance (COP)✓
B)Increased risk of compressor surging
C)Greater refrigerant superheat required
D)Enhanced rate of ammonia decomposition
💡 Explanation
A system imbalance hampers the solution regeneration via desorption, therefore resulting in decreased COP, because absorption efficiency diminishes with increasing deviation from the design equilibrium concentration; and surge, superheat, and decomposition are unrelated, rather than driven by thermodynamic equilibrium conditions.
