← ScienceWhich risk increases when an ammonia absorption refrigeration cycle operates under a fluctuating heat source?
A)Crystallization risk inside cycle's absorber✓
B)Refrigerant overcharge damages the compressor
C)Catalyst poisoning disrupts the desorption
D)System's heat exchanger fins ice over
💡 Explanation
Crystallization risk increases inside the absorber because "temperature cycling" affects the NH3 solubility, dropping it and inducing solute precipitation. Therefore, crystallization can obstruct flow and reduce efficiency, rather than overcharge scenarios or icing elsewhere.
