Which outcome occurs when a refrigerant leak leads to air infiltration in a refrigeration system's evaporator?

💡 Explanation

When air infiltrates the evaporator due to a refrigerant leak, the moisture in the air freezes on the evaporator coil because of low temperatures, leading to ice buildup which insulates the coil, reducing heat transfer. Therefore icing and reduced heat transfer results, rather than other options due to different mechanisms.
