Refrigerant leaves the compressor through the ___________ line.

Refrigerant leaves the compressor through the ___________ line.

• A. Suction
• B. Expansion
• C. Discharge
• D. Liquid

Answer: (C)

In a refrigerant vapor‑compression cycle, the refrigerant leaves the compressor as high‑pressure, high‑temperature gas that must be carried toward the condenser. This outlet path is known as the discharge line. The suction line is what brings the low‑pressure vapor from the evaporator back into the compressor, so it isn’t leaving the compressor. The liquid line carries high‑pressure liquid refrigerant from the condenser to the expansion device, and the expansion/Metering line leads to the evaporator where the refrigerant expands and cools. So the discharge line is the correct path for the refrigerant exiting the compressor.
