Which outcome elevates superheat, influencing TXV function, when a refrigeration evaporator's return airflow sharply decreases, reducing heat absorption?

💡 Explanation

Evaporator coil icing intensifies because diminished airflow triggers the coil's temperature dropping below freezing, leading to ice accumulation on coil surfaces via the latent heat of fusion mechanism; therefore, coil icing results, concentrating cooling power at the ice rather than into useful space cooling, rather than liquid flood-back.
