Which consequence results when an absorption refrigerator cycle’s generator temperature is excessively increased?

A)Crystallization within the absorber tank
B)Ammonia vapor entering the evaporator
C)Reduced coefficient of performance (COP)
D)Increased solution pump cavitation risk

💡 Explanation

When the generator temperature excessively increases, the absorbent salt concentration rises too high, leading to solute precipitation by exceeding its solubility and forming solid crystals in the absorber tank impeding flow. Therefore, crystallization occurs, rather than non-absorbent vapor carryover, efficiency decline, or cavitation which arise from other operational faults.
