摘要

The warehouse has a climate control unit to control the temperature of air from fans and humidifiers in a cooling chamber. The downstream end of each fan is connected to a blind tube of flexible material, where the tube is provided with perforations along its mantle surface, such that air from the fans and humidifiers pass through the perforations into the cooling chamber.
