← TechnologyWhich outcome occurs when partial evaporator blockage restricts a scroll chiller's refrigerant flow?
A)Compressor motor winding overheating✓
B)Reduced condenser subcooling capacity
C)Increased lubricant viscosity breakdown
D)Elevated superheat from expansion valve
💡 Explanation
The restricted refrigerant causes increased compression ratios, requiring more motor power because of increased load. This leads to compressor motor winding overheating due to elevated current, therefore increased winding temperatures, rather than other issues within the cooling system.
