← ScienceWhich outcome results when a refrigeration cycle leak reduces refrigerant mass below the design charge?
A)Reduced cooling capacity and efficiency✓
B)Increased compressor motor current draw
C)Evaporator coil freezing due to ice
D)Condenser fan overheating from backpressure
💡 Explanation
When refrigerant mass decreases, heat transfer decreases because less mass changes phase through the evaporator/condenser, leading to reduced heat absorption and rejection and therefore lowered cooling capacity. Therefore cooling suffers, rather than overload, icing, or fan failure which require more extreme conditions or different component failure modes.
