🔍 Key Concepts

• Liquid-line solenoid valve function in an off cycle • What happens to refrigerant migration when a valve leaks during shutdown • How reciprocating compressors react to liquid refrigerant at startup

💭 Think About

• Think about where the refrigerant can slowly move if the liquid-line solenoid does not fully close during the off cycle. • When the system restarts after refrigerant has leaked past the solenoid, what physical condition will the compressor face at the very first few revolutions? • Which of the options describes a condition that is most likely to occur suddenly at startup due to unwanted liquid in places it should not be?

✅ Before You Answer

• Verify which answer choices relate to startup effects versus running conditions. • Check which option would be a direct result of liquid refrigerant entering areas that should have mainly vapor during startup. • Eliminate any answers that describe conditions more associated with long-term operating imbalance rather than a brief off-cycle leak.
