← TechnologyWhich outcome predominates with excessive superheat at the evaporator outlet in a refrigeration system?
A)Reduced cooling capacity output✓
B)Increased compressor discharge pressure
C)Flooding of liquid refrigerant
D)Oil dilution in the crankcase
💡 Explanation
When superheat is excessive, it means all the liquid refrigerant has evaporated well before the evaporator outlet, leaving a large section unused. Unevaporated refrigerant isn't doing latent heat exchange and providing its intended latent cooling. Therefore, reduced cooling capacity appears, rather than discharge pressure, flooding or dilution, which arise due to different issues.
