Which refrigerant type is commonly used in centrifugal compressors?

• A. Ammonia
• B. R-12
• C. R-134a
• D. All of the above

Answer: (D)

Centrifugal compressors are versatile and can accommodate various refrigerants, which makes them suitable for a range of applications in commercial and industrial refrigeration. Ammonia is a widely used refrigerant in large-scale systems due to its efficiency and thermodynamic properties, making it a common choice for centrifugal compressors in industrial setups. R-12, while phased out in most applications due to environmental regulations, was historically used in refrigeration systems and can still be found in some older systems utilizing centrifugal compressors. R-134a, a hydrofluorocarbon (HFC), has become popular in newer refrigeration and air conditioning applications, including those utilizing centrifugal compressors, due to its lower ozone depletion potential compared to R-12. Given that all these refrigerants can be used in centrifugal compressors, selecting "all of the above" acknowledges the diverse applications and historical use of these different refrigerants in systems leveraging centrifugal compression technology.
