The refrigerant line that connects the condenser to the metering device is the __________ line.

The refrigerant line that connects the condenser to the metering device is the __________ line.

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

Answer: (C)

After the condenser, the refrigerant is a high-pressure liquid. It flows through the liquid line to the metering device, where its pressure is reduced before it enters the evaporator. This distinguishes it from the discharge line, which carries high-pressure gas from the compressor to the condenser, and the suction line, which returns low-pressure vapor from the evaporator to the compressor. The expansion happens inside the metering device rather than in a separate line, so the path from condenser to metering device is called the liquid line.
