Question 30Refrigeration/AC - 1st Asst/Chief70% to pass
Traditionally, which of the listed refrigerants has been more suitable than the others for use in a centrifugal refrigeration compressor?
AI Explanation
The correct answer is A) R-11.
Traditionally, R-11 (trichlorofluoromethane) has been more suitable than other refrigerants for use in a centrifugal refrigeration compressor. R-11 has a low boiling point and high density, which makes it well-suited for the high-pressure, high-volume requirements of centrifugal compressors. The other options, such as R-12 (dichlorodifluoromethane), ammonia, and carbon dioxide, have different properties that are less ideal for centrifugal compressor applications.
