Refrigerant leaves the compressor through which line?

Refrigerant leaves the compressor through which line?

• A. Discharge line
• B. Suction line
• C. Liquid line
• D. Service line

Answer: (A)

Path of refrigerant after compression: refrigerant leaves the compressor through the discharge line. The compressor takes in low‑pressure refrigerant vapor from the evaporator via the suction line and, by compressing it, raises its pressure and temperature. That high‑pressure vapor exits the compressor through the discharge line and heads to the condenser to reject heat and condense into a liquid. The suction line is the inlet to the compressor, not the outlet, and the liquid line carries liquid refrigerant from the condenser to the expansion device and evaporator, not from the compressor. The service line is used for testing or servicing ports, not part of the normal cycle.
