Q

Which of the refrigerants listed is considered as a suitable and limited ozone producing alternative for R-11?

🔍 Key Concepts

• Environmental impact and ozone depletion potential (ODP) of common marine refrigerants • Differences between CFCs, HCFCs, and HFCs in terms of ozone damage • Which refrigerants are used as low-ODP replacements for older CFCs like R-11

💭 Think About

• First, recall what type of refrigerant R-11 is and why it was phased down under environmental regulations. • Think about which option is specifically known as a replacement for R‑11 in larger systems, not just any common refrigerant. • Consider which choices are primarily associated with ozone-friendly characteristics versus reduced but not zero ozone depletion.

✅ Before You Answer

• Identify which choices are HCFCs (hydrochlorofluorocarbons) versus HFCs (hydrofluorocarbons). • Verify which option was historically adopted as a direct or near-direct R‑11 substitute in centrifugal chillers. • Check which refrigerant is described as having lower but not zero ODP, matching the phrase “limited ozone producing.”
