Abstract

An automated grid based storage and retrieval system includes a framework structure. The framework structure includes upright members and a grid of horizontal rails provided at upper ends of the upright members. The framework structure defines at least one storage volume below the horizontal rails. The at least one storage volume includes a plurality of storage, a plurality of walls, a first plenum, a first plurality of transversally directing air ducts, a first and second plurality of horizontally directing air ducts, and a cooling system. The plurality of storage columns are arranged adjacent one another. The plurality of walls surround an outer extent of the plurality of storage columns. The first plenum extend horizontally beneath the storage columns. The first plurality of transversally directing air ducts are connected to at least one fan adapted to draw air from outside the at least one storage volume. The first plurality of horizontally directing air ducts are positioned to distribute the air horizontally below the horizontal rails to provide a first horizontal air curtain. The cooling system is adapted to draw air from the first plenum, cool the air, and blow cooled air from an output of the cooling system as a cooled airflow. The second plurality of horizontally directing air ducts are adapted to receive the cooled airflow from the cooling system through a first air damper, the second plurality of horizontally directing air ducts being positioned at a level below the first plurality of horizontally directing air ducts to distribute at least a first portion of the cooled airflow horizontally above an uppermost layer of the storage columns.
