Which outcome occurs when glycol concentration decreases entering an evaporator coil?

💡 Explanation

Ice forms because the reduced glycol concentration raises the coolant's freezing point via freezing-point depression. This causes ice formation on the coil, therefore blocking airflow and reducing heat exchange, rather than enabling continued cooling at the design point.
