🔍 Key Concepts

• Compressor protection and what type of refrigerant (liquid or vapor) should enter the compressor suction • What happens if liquid refrigerant gets to places designed only for vapor in the system • Normal functions of condenser, liquid line, receiver, and suction line in a basic refrigeration cycle

💭 Think About

• In a properly operating system, what phase (liquid or vapor) is supposed to enter the compressor through the suction line? • Which system component is directly connected to the compressor suction side? Think about where any "flooding back" would be noticed or cause damage. • Which of the listed options (condenser, suction line, liquid line, receiver) would be the most dangerous place for liquid refrigerant to appear unexpectedly?

✅ Before You Answer

• Be clear on the normal refrigerant flow path: compressor → condenser → receiver → expansion device → evaporator → back to compressor. • Confirm in your mind which line carries low‑pressure vapor back to the compressor under normal conditions. • Check which choice specifically mentions the compressor suction side, since flooding back is mainly a compressor problem.
