Show Hint
Remember the path of energy flow:
- Low-Pressure Vapor (Evaporator) \(\rightarrow\) High-Pressure Vapor (Compressor) \(\rightarrow\) High-Pressure Liquid (Condenser) \(\rightarrow\) Low-Pressure Liquid (Expansion Device).
- Low-Pressure Vapor (Evaporator) \(\rightarrow\) High-Pressure Vapor (Compressor) \(\rightarrow\) High-Pressure Liquid (Condenser) \(\rightarrow\) Low-Pressure Liquid (Expansion Device).

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
A standard vapor-compression refrigeration cycle consists of four continuous, thermodynamic processes executed by four primary components in a closed loop.
Detailed Explanation:
Let us trace the flow of the working fluid (refrigerant) starting from the evaporator:
1. Evaporator (A): Liquid refrigerant at low pressure and temperature absorbs heat from the refrigerator compartment, boiling and evaporating into a low-pressure vapor.
2. Compressor (B): The low-pressure vapor is drawn into the compressor, where it is mechanically compressed into a high-pressure, high-temperature superheated vapor.
3. Condenser (C): The high-pressure vapor flows into the condenser, where it rejects heat to the ambient room air, condensing into a high-pressure liquid.
4. Expansion Device (D): The high-pressure liquid passes through the expansion device (such as a capillary tube), where its pressure and temperature drop rapidly. It then re-enters the evaporator to repeat the cycle.
This cycle follows the sequence: Evaporator \(\rightarrow\) Compressor \(\rightarrow\) Condenser \(\rightarrow\) Expansion device.
This corresponds to the sequence (A), (B), (C), (D), making Option (A) the correct choice.
Step 2: Final Answer:
The correct sequence is (A), (B), (C), (D).
