Question

Sequentially arrange the system of refrigeration cycle: A. Condensation B. Compression C. Evaporation D. Expansion E. Return to compressor

• A. B, A, D, C, E
• B. B, D, A, C, E
• C. B, C, D, A, E
• D. B, E, A, D, C

Hint:

Remember that in a refrigeration cycle, compression increases pressure and temperature, condensation cools the vapor to liquid, expansion reduces pressure allowing for evaporation, and evaporation occurs in the evaporator where heat is absorbed.

Answer 1

The Correct Option is A

Step 1: Concept
The refrigeration cycle involves a series of processes that transfer heat from one place to another using a working fluid. These processes include compression, condensation, expansion, and evaporation.

Step 2: Meaning
In the context of this question, we need to correctly sequence the steps in a typical refrigeration cycle as they are presented in the options provided.

Step 3: Analysis
1. Compression (B): This is the first step where the low-pressure refrigerant vapor is compressed by the compressor, increasing its pressure and temperature. 2. Condensation (A): The high-temperature, high-pressure vapor from compression is cooled and condensed into a liquid in the condenser. 3. Expansion (D): The liquid refrigerant then passes through an expansion valve or device where it undergoes a sudden reduction in pressure, causing it to flash partially into a low-pressure vapor. 4. Evaporation (C): The now low-temperature, low-pressure mixture of vapor and liquid enters the evaporator where it absorbs heat from the environment and fully vaporizes. 5. Return to Compressor (E): The process is completed when the refrigerant vapor returns to the compressor. The correct sequence based on these steps is B, A, D, C, E.

Step 4: Conclusion
The given options are: A) B, A, D, C, E B) B, D, A, C, E C) B, C, D, A, E D) B, E, A, D, C Option A (B, A, D, C, E) is the correct sequence. Final Answer: (A)
