← ScienceWhich consequence results when an absorption chiller's generator overheats?
A)Ammonia decomposition yields non-condensable gases✓
B)Lithium bromide precipitates forming crystalline solids
C)Water hammer damages the pump impeller
D)Refrigerant migration causes evaporator dry-out
💡 Explanation
Ammonia decomposition occurs upon overheating because high temperatures break down the ammonia molecules via thermal decomposition. This forms non-condensable gases that interfere with condensation, therefore lowering the chiller's efficiency rather than causing precipitation of lithium bromide or refrigerant migration.
