Which of the fluids listed is normally used to condense the primary refrigerant in an indirect shipboard central air conditioning system?

🔍 Key Concepts

• Indirect refrigeration systems on ships (primary vs. secondary refrigerant) • Typical condensing medium for marine refrigeration and A/C plants • Difference between cooling water and chilled brine in the system

💭 Think About

• First, think about what component actually condenses the primary refrigerant (like R‑22/R‑134a) and what that fluid’s job is. • Ask yourself: which of these fluids is normally available in large quantity on a ship to take away heat and discharge it overboard or to the atmosphere? • Consider which listed fluids are more commonly used on the evaporator/chill side (secondary refrigerant) versus the condenser side of the system.

✅ Before You Answer

• Identify which option(s) are used as cooling water to remove heat from the condenser rather than as a chilled medium circulated to air handlers. • Verify which brines (if any) are typically found on the low‑temperature/chilled side instead of the condenser side. • Eliminate any fluids that would be impractical or uncommon as a ship’s main condensing medium for a central A/C plant.
