Which refrigerant path carries high-pressure vapor from the compressor to the condenser?

Which refrigerant path carries high-pressure vapor from the compressor to the condenser?

• A. Discharge line
• B. Suction line
• C. Liquid line
• D. Capillary tube

Answer: (A)

High-pressure vapor flows from the compressor into the condenser through the discharge line. After the compressor compresses the refrigerant, its pressure and temperature rise, and this hot, high-pressure vapor exits the compressor and travels through the discharge line to the condenser where it rejects heat and becomes a liquid. The suction line carries low-pressure vapor back to the compressor from the evaporator, the liquid line carries high-pressure liquid from the condenser toward the metering device, and the capillary tube is a throttling device in the liquid line that reduces pressure, not a path for vapor from the compressor to the condenser.
