In which state does refrigerant leave the compressor?

• A. Subcooled state
• B. Sensible phase
• C. Superheated state
• D. Latent phase

Answer: (C)

Refrigerant leaves the compressor in a superheated state. When the refrigerant is compressed, its pressure and temperature rise significantly. The compressor's primary function is to increase the pressure of the refrigerant vapor, which raises its temperature above the saturation point. This process ensures that the refrigerant is in a gaseous state when it exits the compressor, allowing it to effectively enter the condenser.

Additionally, a superheated refrigerant carries more energy and ensures that there is no liquid refrigerant entering the compressor, which could lead to potential damage. By being superheated, the refrigerant is fully vaporized and ready for the heat exchange process that occurs in the condenser, where it will lose heat and eventually condense into a liquid. This understanding is crucial for anyone working with refrigerants and HVAC systems, as it emphasizes the importance of maintaining the correct phase of refrigerant throughout the cycle.
