🔍 Key Concepts

• Dew point and condensation: Moist air entering a cooler space can cause sweat (condensation) on cargo or structure. • Cargo sweat vs. ship’s sweat: Know which one happens when warm, moist air meets a cold surface, and how ventilation affects each. • Ventilation strategy: How do intake and exhaust blowers change the temperature and moisture content of hold air?

💭 Think About

• If outside air has a lower or equal dew point than the hold air, what does that say about the outside air’s moisture content compared to the air in the hold? • Would bringing in this outside air make condensation on cargo surfaces more or less likely? Why? • In this situation, is it safer to increase the exchange of air between outside and hold, or to reduce it? Which blower(s) directly control bringing outside air in?

✅ Before You Answer

• Compare outside dew point vs. hold dew point to decide if outside air is drier or more humid. • Think about whether you want to add drier air to the hold or trap more humid air inside. • Identify which system (intake vs. exhaust) actually introduces outside air into the cargo space.
