Vapor-compression cycle component functions: where is heat rejected? During the standard refrigeration cycle, identify the component in which the refrigerant rejects heat to the surroundings. Choose the correct component.

Difficulty: Easy

Compressor
Condenser
Evaporator
Expansion valve

Correct Answer: Condenser

Explanation:

Cycle roles

Evaporator: absorbs heat (Q_L) from the refrigerated space at low T and p.
Compressor: adds work; raises pressure and saturation temperature.
Condenser: rejects heat (Q_H) to ambient; vapor condenses to liquid.
Expansion valve: throttles to low p, producing a low-temperature mixture.

Final Answer
Condenser
