Which of the following is a widely used refrigerant in vapour compression refrigeration system (using large centrifugal compressor) ?
Correct answer: A. Freon
- A. Freon
- B. Liquid sulphur dioxide
- C. Methyl chloride
- D. Ammonia
Explanation
Large centrifugal refrigeration compressors have historically used Freons such as R-11 and R-12 because of their suitable pressure and volumetric characteristics. Ammonia is widely used in refrigeration, but more commonly with reciprocating or screw compressors in this context.
