🔍 Key Concepts

• Behavior of non-condensable gases (like air) in a refrigeration condenser • Relationship between condenser pressure and refrigerant saturation temperature • Effects of air on heat transfer and condenser efficiency

💭 Think About

• Compare what happens to condenser pressure when non-condensable gases are present versus when only pure refrigerant vapor is present. • Think about how you normally match head (discharge) pressure to the saturation temperature of the refrigerant in the condenser—what would trapped air do to this relationship? • Consider which symptoms would be caused directly by pressure/temperature mismatch rather than changes in refrigerant quantity.

✅ Before You Answer

• Check which option mentions pressure compared to refrigerant temperature, not just pressure alone. • Verify which symptom points to non‑condensable gas taking up space in the condenser and reducing effective condensing surface. • Eliminate choices that mainly suggest too much or too little refrigerant instead of contamination with air.
