Which of the following units is not present in both the vapor compression refrigeration system and absorption refrigeration system ?
Correct answer: D. Compressor
- A. Expansion valve
- B. Condenser
- C. Refrigerator
- D. Compressor
Explanation
Vapour-compression systems use a mechanical compressor, whereas absorption systems replace it with an absorber, pump, generator and related components. Both systems still contain a condenser and expansion device, so the compressor is the missing unit.
