Q

Unusually heavy frosting or sweating of the suction line of a reciprocating refrigeration compressor indicates a condition which could result in severe damage due to what condition?

🔍 Key Concepts

• Refrigerant condition at the compressor suction (vapor vs. liquid) • Effects of liquid refrigerant entering a reciprocating compressor • Relationship between frosting/sweating on the suction line and temperature/pressure in that line

💭 Think About

• Ask yourself what the suction line should normally be carrying into the compressor: superheated vapor, saturated mixture, or liquid? • Think about what happens mechanically inside a reciprocating compressor if an incompressible fluid enters the cylinders. • Consider which of the listed options would most likely cause the suction line temperature to drop so much that it frosts heavily.

✅ Before You Answer

• Verify which option involves liquid refrigerant reaching the compressor suction rather than just vapor. • Check which conditions would typically show up as low suction line temperature with heavy frost or sweat, versus conditions that primarily affect system capacity or valve performance. • Eliminate any choice that does not directly threaten mechanical damage to the compressor internals.
