System and method of temperature control in an automated grid based storage and retrieval system

An automated grid based storage and retrieval system, comprising:

• a framework structure comprising upright members and a grid of horizontal rails provided at upper ends of the upright members, the framework structure defining a plurality of storage volumes arranged adjacent one another below the horizontal rails,
• a plurality of vertical walls surrounding at least one of the plurality of storage volumes,
• a cooler system adapted to draw air from an input of the cooler system, cool the air drawn from the input, and blow cooled air through an output of the cooler system,
• for the at least one storage volume, the system further comprises a first air damper connected between the output of the cooler system and an air release area above the storage volume, and a second air damper connected between a lowermost layer of the storage volume and the input of the cooler system,
• a controller, wherein the controller is adapted, for the at least one storage volume, to adjust airflow through the first air damper associated with that storage volume to control an overpressure and air temperature in the air release area, and to adjust airflow through the second air damper associated with that storage volume to control a pressure differential through the respective storage volume.
