← ScienceWhich outcome results when a refrigeration cycle's evaporator coil ices over completely?
A)Reduced cooling capacity and compressor overheating✓
B)Increased energy efficiency and longer cycle times
C)Lower refrigerant pressure and decreased power consumption
D)Enhanced heat transfer and stabilized system temperatures
💡 Explanation
When the evaporator coil ices over, the thermal resistance increases because the ice acts as an insulator, reducing heat transfer and causing compressor overheating due to inefficient refrigerant evaporation. Therefore reduced cooling and compressor overheating result, rather than efficiency increases, lower pressure, or enhanced transfer, which require effective heat exchange.
