Excessive moisture being collected in the purge unit of a low-pressure refrigeration system could indicate which probable condition?

🔍 Key Concepts

• Function of a purge unit in a low-pressure refrigeration system • What causes noncondensable gases and moisture to enter a low-pressure system • How a tube leak between refrigerant side and water side would appear in system operation

💭 Think About

• Ask yourself: How does moisture physically get into a low-pressure chiller that normally should be a closed system? • Consider which option describes a source of water entering the refrigerant circuit, versus a downstream symptom or maintenance issue. • Think about what the purge unit is supposed to remove—if it’s collecting excessive moisture, what upstream failure could be feeding it?

✅ Before You Answer

• Identify which choice represents an actual path for water to enter the refrigerant side (water side vs refrigerant side). • Separate root cause problems from effects: is the purge unit’s efficiency the cause, or just how it handles what’s already in the system? • Decide which option would most directly explain a sudden increase in moisture being removed, not just normal aging or minor system imbalance.
