← TechnologyWhich risk increases when the scroll compressor outflow valve in a large-scale LNG pump fails closed?
A)Compressor motor thermal overload✓
B)Expansion valve refrigerant starvation
C)Decreased evaporator superheat margin
D)Increased condenser subcooling level
💡 Explanation
Compressor motor thermal overload risk increases because a closed outflow valve leads to rapid recirculation and extreme compression, causing the refrigerant temperature to spike excessively activating thermal protection, therefore the motor is affected, rather than refrigerant levels experiencing imbalances.
