Air Cooler Installation Layout, Clearance Requirement & Airflow Design
Air cooler installation layout determines cold room temperature uniformity; wrong position creates dead corner, product temperature difference and partial frost accumulation. General installation rule: air cooler mounted on upper wall or ceiling, cold air blows parallel to cargo stacking channel, return air path unobstructed. Minimum clearance: front air outlet ≥800 mm free space; top space ≥300 mm for maintenance; rear return side ≥400 mm away from wall or insulation. Distance between air cooler and top pallet goods must reserve at least 400 mm; stacked goods cannot block air jet flow from fan outlet. Xiteliduo air cooler HS 84186120 provides dimension drawing and airflow envelope for cold room designer to arrange layout in CAD. Long rectangular cold room usually deploys multiple air coolers along two side walls, airflow cross blowing to cover whole storage space evenly. Blast freezer air cooler installs at the end of conveyor tunnel; high-speed cold air sweeps across product surface in counter-flow arrangement. Air cooler should avoid direct blowing on packaged fresh meat, fruits and vegetables; direct wind causes surface dehydration and quality loss. Door opening area is high heat infiltration zone; air cooler return air inlet should not be close to cold room door to avoid sucking in warm humid outside air. Refrigeration maintenance & repair company marks airflow direction during commissioning; observe whether all cargo zones can reach set temperature within design time.
FAQ
- What minimum clearance in front of air cooler air outlet? ≥800 mm free space.
- What clearance on top of air cooler for maintenance? ≥300 mm.
- What gap between air cooler outlet and top layer cargo pallet? ≥400 mm.
- What layout for long rectangular cold room to get uniform temperature? Multiple air coolers arranged on side walls with cross blowing airflow.
- What airflow arrangement for tunnel blast freezer air cooler? Counter-flow high-speed air across moving product.
- Why avoid direct air jet on fresh produce and meat? Direct airflow leads to surface moisture loss and quality deterioration.
- Why not place air cooler return opening near cold room door? Easy to suck in warm humid outside air and accelerate frost build-up.
- What is the sign of poor air cooler layout design? Large temperature difference between different zones inside cold room.
