Development of an energy saving ventilation regime for fruit and vegetable cold stores
Spatial profiling of airflow conditions in cold storage warehouses by wireless anemometers
A set of 23 wireless anemometers (WAMs) was deployed to capture the spatial airflow profile in a vertical gap between bins in a cold-storage warehouse filled with apples. Horizontal and vertical air velocity were measured separately and combined to magnitude and angle. The measurements showed large variations in velocity from 0.34 m/s to 1.5 m/s depending on the location. The results were verified by computational fluid dynamics simulation. As one pre-requisite for automated fan revolution (FR) control, the effect of reduced FR on the velocity between the boxes was measured. Especially for low FR, the accuracy of the WAMs has to be improved, before automated fan control can be put into practice.
