← ScienceWhich consequence results when a refrigeration cycle operates outside design temperatures?
A)Inefficient refrigerant phase change occurs✓
B)Excessive compressor head pressure results
C)Capillary tube blockage becomes likely
D)Evaporator coil freezes and cracks
💡 Explanation
Reduced operating temperature inhibits the refrigerant phase change, because of decreased heat transfer across evaporator and condenser. Less efficient phase change therefore leads to reduced overall cooling capacity rather than higher pressure elsewhere.
