Which risk increases when a chiller's refrigerant feed contains non-condensable gases?

💡 Explanation

Reduced heat exchanger effectiveness occurs because non-condensables accumulate at condenser surfaces causing increased thermal resistance, the mechanism being reduced partial pressure. Therefore, heat transfer decreases, rather than more effective heat transfer from pressure changes.
