Question 1 of 27070

Which of the following refrigerants is normally classified as a low-pressure refrigerant based on a relatively high boiling point?

🔍 Key Concepts

• Refrigerant pressure classes (low, medium, high) and what they are based on • Relationship between boiling point and operating pressure in a refrigeration system • Typical applications where low-pressure refrigerants (chillers, large AC plants) are used

💭 Think About

• How does a higher boiling point affect the saturation pressure of a refrigerant at normal room or chiller temperatures? • Which of the listed refrigerants is commonly associated with large low-pressure centrifugal chillers? • Compare which of these refrigerants typically operates under vacuum or near-atmospheric pressure on the low side of the system.

✅ Before You Answer

• Look up or recall the approximate boiling point of each listed refrigerant • Verify which refrigerant is commonly described in manuals as a low-pressure refrigerant used in large chillers • Check which option has a much higher boiling point (less negative temperature) than the others, leading to a lower system pressure
