• Reducing thermal stratification and humidity imbalance in a high-ceiling space
• Eliminating stagnant airflow between seven cultivation tiers
• Building three-dimensional air circulation for uniform growing conditions

Severe vertical temperature differences

Warm air accumulated above the racks, producing significant differences in crop growth rates between the first and seventh tiers.

Rack structures obstructing airflow

Seven tiers of growing shelves formed barriers to circulation. Humidity accumulated deep within the racks, increasing the risk of pests and disease.

Limits of conventional overhead air supply

Simply sending air downward from above could not maintain uniform temperature and humidity throughout the large vertical space.

Downward airflow reaching lower tiers

Overhead fabric ducts were designed to deliver effective airflow to the lower cultivation tiers, reducing vertical temperature differences even in spaces over 7 m high.

Effective delivery across the vertical growing area

Overhead fabric ducts directed airflow down to the lower cultivation tiers, helping reduce temperature differences throughout the high-ceiling growing space.

Air distribution for uniform temperature and humidity

Air volume and discharge directions were adjusted for the seven crop tiers rather than the empty space, minimizing temperature and humidity differences between levels.

Uniform growing conditions from top to bottom

Despite the large 7 m vertical difference, temperature and humidity differences were stabilized at levels that did not affect growth, enabling uniform harvesting across the seven tiers.

Eliminating stagnant-air zones

Fresh air and CO₂ reached inside the complex seven-tier structure, improving crop vitality and significantly reducing the occurrence of pests and disease.

Efficient HVAC for a large space

Auxiliary circulation devices working with fabric ducts improved HVAC operating efficiency and reduced the costs of running the large smart farm.
