← ScienceWhich outcome occurs when increased resistance affects a refrigeration cycle?
A)Reduced coefficient of performance (COP)✓
B)Increased compressor motor lifespan
C)Enhanced refrigerant subcooling levels
D)Decreased condenser heat rejection load
💡 Explanation
A refrigeration cycle's COP decreases with increased resistance due to throttling; because this expansion degrades cycle efficiency. Specifically, increased irreversibility from friction during vapor compression, therefore COP is reduced in cooling rather than having the other effects.
