← ScienceWhich outcome results from a refrigeration system coil icing?
A)Decreased system cooling capacity.✓
B)Increased compressor power draw.
C)Elevated refrigerant subcooling degree.
D)Optimized heat exchanger effectiveness.
💡 Explanation
Icing reduces cooling capacity via thermal insulation, caused by *latent heat transfer* from water *phase transition*. Therefore, system cooling decreases, rather than alternatives such as increased compression because refrigerant flow remains impaired.
