Which risk increases when a refrigeration system's evaporator undergoes excessive ice crystal formation?

💡 Explanation

Reduced COP occurs because the mechanism of ice formation adds insulation, raising the thermal resistance within the evaporator, therefore heat transfer decreases, rather than component damage or chemical alteration of the refrigerant.
