Which of the following refrigerants will normally require a compressor that is water cooled?

Question 1 of 27070

Which of the following refrigerants will normally require a compressor that is water cooled?

🔍 Key Concepts

• Relationship between system size / operating pressure and the need for water cooling on compressors • Typical marine and industrial uses of ammonia vs. halocarbon refrigerants (like R‑22 and R‑134a) • Differences between air‑cooled and water‑cooled compressor arrangements on ships

💭 Think About

• Think about which refrigerant is most commonly found on large-capacity, industrial or marine refrigeration plants that run continuously and generate a lot of heat at the compressor. • Ask yourself which refrigerants are more often used in smaller, self‑contained or domestic-style systems that can easily reject heat to air without water cooling. • Consider how safety, toxicity, and plant location (e.g., separate machinery room vs. small package unit) influence the type and cooling method of the compressor.

✅ Before You Answer

• Check which refrigerant is most associated with large marine cargo refrigeration and industrial plants. • Verify which refrigerants are commonly used in domestic, automotive, or small HVAC systems and how those compressors are usually cooled. • Before choosing “All of the above”, confirm that each individual refrigerant on the list is normally found with water‑cooled compressors in typical marine practice.
