Question 78Refrigeration/AC - 1st Asst/Chief70% to pass
Zinc plates commonly found in refrigeration systems and used as sacrificial anodes are located where?
AI Explanation
The correct answer is C) saltwater side of the condenser.
Zinc plates are used as sacrificial anodes in refrigeration systems to protect the condenser from corrosion, specifically on the saltwater side of the condenser. Sacrificial anodes are made of a metal that is more electronegative than the metal of the condenser, causing the zinc to corrode preferentially and protect the condenser from galvanic corrosion.
The other options are incorrect because the refrigerant side of the condenser (A) and the evaporator coils (D) do not require sacrificial anodes, and the cooling water suction strainer (B) is not the location for the zinc plates.
