Freshly harvested fruits and vegetables in hot dry climates need to be quickly cooled for preservation. Typical cooling systems use mechanical refrigeration, which requires high capital cost and energy consumption. Evaporative cooling provides a cool and humid environment with lower energy consumption and half the cost of refrigerated cold rooms. By using cooling with forced airflow this chamber design is ideal for the pre-cooling of fruits and vegetables in dry regions. The forced-air evaporative cooling chamber detailed in these documents provides a cost-effective solution for storing fruits and vegetables in hot and dry climates.
