Abstract
A multi-temperature storage system, including: a grid framework structure (GFS) including: a supporting framework structure (SFS) including storage columns arranged to accommodate storage containers, said SFS including a load bearing assembly of supporting walls at least one of which is a thermally insulating panel that separates the storage columns into first and second groups to define temperature storage zones; a track system for guiding movement of robotic load handling devices on the GFS mounted to the SFS and including a tracks arranged in a grid pattern including grid cells extending across the storage cells such that each modular storage cell supports a sub-group of two or more grid cells of the track system; a radiant cooling system including a cooling unit and a closed network of tubing in fluid communication with the cooling unit, the closed network extending in the first temperature storage zone.
