Which outcome arises when a heat exchanger fin corrodes from increased moisture and salinity?

💡 Explanation

When the heat exchanger fin corrodes, thermal resistance increases because the reduced metal surface area diminishes the conduction path, impairing effective heat transfer. Therefore, reduced heat transfer efficiency results, rather than altering subcooling, pressure or superheat which rely on refrigerant properties and flow.
