Airflow stratification forms when cold air sinks and warm air rises inside high rack cold storage. Vertical temperature difference appears across rack layers. Denser cold air accumulates at lower levels while warmer air stays in upper zone, creating inconsistent product storage temperature. Xindacool air cooler layout and air deflector configuration are customized according to rack height, aisle width and pallet layout. Air outlet angle controls jet range. Downward directed airflow penetrates deeper into rack aisles and reduces vertical temperature gap. Air return opening position also affects stratification. Return air placed too high pulls upper warm air and worsens temperature difference. High stacking height reduces air mixing. Static air layers form between pallet rows and prevent cold air from vertical circulation. Higher fan static pressure helps push cold air through long rack aisles. Insufficient fan pressure leaves dead zones deep inside rack system. Temperature sensors should be installed on different vertical heights. Multi-point readings reveal hidden stratification that single sensor cannot detect. Warehouse door frequent opening introduces warm air. Warm air accumulates at upper part and enlarges vertical temperature difference. Adjust fan speed in partial load periods. Reduced fan speed may weaken air mixing and make stratification more obvious. For ultra-high rack cold room, multiple air coolers are distributed evenly. Single unit cannot eliminate stratification across large vertical space.
Q: What is airflow stratification in high rack cold room? A: Cold air sinks downward, warm air stays upper and creates vertical temperature difference. Q: How air deflector helps reduce temperature layering? A: Adjust air jet angle to push cold air deeper into rack aisles and enhance air mixing. Q: Why install temperature sensors at multiple vertical positions? A: Capture temperature difference across height and detect airflow stratification. Q: What worsens stratification when warehouse door opens often? A: Incoming warm air accumulates in the upper space of cold room. Q: What effect of insufficient fan static pressure? A: Cold air cannot penetrate deep racks and static air dead zones appear. Q: Can reducing fan speed increase stratification risk? A: Yes, lower airflow weakens air mixing inside the warehouse. Q: Why ultra-high rack room uses multiple air coolers? A: Single unit cannot provide enough circulation to eliminate vertical temperature stratification. Q: How air return position influences stratification? A: Return air opening too high draws upper warm air and increases temperature difference.
