Air-refrigeration cycle________________?
Correct answer: D. Both B. and C
- A. Is the most efficient of all refrigeration cycles
- B. Has very low efficiency
- C. Requires relatively large quantities of air to achieve a significant amount of refrigeration
- D. Both B. and C
Explanation
Air refrigeration has a low coefficient of performance and requires a high mass flow rate because air has a relatively low refrigeration effect per unit mass. Both statements B and C are therefore valid.
