Which outcome occurs when ethylene glycol concentration significantly decreases within a chiller evaporator?

💡 Explanation

When ethylene glycol concentration decreases, the freezing point of coolant mixture rises because it lowers total concentration, causing water to freeze onto the evaporator coil. Therefore ice formation results rather than superheat, elevated compressor temperatures, or unchanged system pressures, which are associated with refrigerant related or pump problems.
