In a vapor compression refrigeration system, the refrigerant undergoes compression, which increases its pressure and temperature. At the exit of the compressor, the refrigerant is typically in a superheated vapor state.
Saturated liquid: Refers to a liquid that is at its boiling point, and this is not the state at the exit of the compressor.
Wet vapor: Refers to a mixture of liquid and vapor, which is not the case after the refrigerant exits the compressor.
Dry saturated vapor: Is the state where the vapor is fully vaporized but at the boiling point. After the compressor, the refrigerant is usually in a superheated state.
Superheated vapor: This is the correct answer. This is the condition of the refrigerant after compression, where it is heated beyond its boiling point.
