In an industrial ammonia refrigeration system, which outcome occurs when the evaporator's thermal contact degrades?

💡 Explanation

Rising superheat at the evaporator coil exit occurs because diminished thermal contact impedes heat absorption. Therefore, the refrigerant vaporizes less efficiently, leading to higher superheat, rather than alternative outcomes like decreased temperatures or increased subcooling due to other factors.
