Sea water or low temperature central fresh water is typically provided to a ship's stores refrigeration plant for what purpose?

🔍 Key Concepts

• Vapor‑compression refrigeration cycle (compressor, condenser, expansion device, evaporator) • Role of sea water or low‑temperature fresh water in heat exchangers • Difference between superheating and condensing in a refrigeration system

💭 Think About

• In the refrigeration cycle, which component normally has cooling water flowing through it—motor windings, expansion valve body, or a heat‑exchanger surface for the refrigerant? • What has to happen to high‑pressure refrigerant vapor after it leaves the compressor so that it can be reused effectively in the cycle? • Is sea water typically used to control refrigerant temperature at the expansion valve, or to remove a large amount of latent heat from the refrigerant?

✅ Before You Answer

• Identify which part of the system is actually water‑cooled in a typical ship’s stores refrigeration plant • Recall that condensing involves removing latent heat from a vapor so it changes phase to liquid • Distinguish between superheating (raising vapor temperature above saturation) and condensation (cooling vapor below saturation so it becomes liquid)
