What does the suction line in a refrigeration system consist of?

• A. Liquid refrigerant
• B. Hot vapor
• C. Cool vapor
• D. Gas saturated refrigerant

Answer: (C)

The suction line in a refrigeration system is designed to transport low-pressure refrigerant vapor from the evaporator to the compressor. This vapor consists of refrigerant that has absorbed heat from the environment, which causes it to change phase from liquid to gas. The correct characterization of the refrigerant in the suction line is cool vapor, as it has absorbed heat, thus cooling down the surrounding area before it moves back into the compressor. Cool vapor passing through the suction line is essential for the efficiency of the refrigeration cycle, as it ensures that the compressor receives the refrigerant in a gaseous state, allowing it to compress the vapor and maintain the cycle effectively. In contrast, the other choices do not accurately represent the state of the refrigerant in the suction line. Liquid refrigerant is associated with the liquid line, while hot vapor and gas-saturated refrigerant do not describe the ideal state of the refrigerant immediately before it enters the compressor in the suction line.
