An automated grid based storage and retrieval system includes a framework structure and a plurality of storage containers. The framework structure includes upright members and a grid of horizontal rails provided at upper ends of the upright members. The framework structure defines a storage volume including a plurality of columns arranged in a grid pattern below the horizontal rails between the upright members. The plurality of storage containers are stacked vertically in stacks in the columns to provide a plurality of storage columns. An under-stack void extends beneath the stacks of storage containers. A plurality of inlets lead to the under-stack void between the stacks of storage containers. At least one column, which is empty of storage containers and arranged amongst the storage columns, provides a ventilation column. The ventilation column includes a fan. A plurality of duct walls surrounding the ventilation column define a duct having a first end adjacent the horizontal rails and a second end adjacent the under-stack void. The fan is arranged to circulate gas along sides of the stacks, via the plurality of inlets and the under-stack void, and through the duct.

A refrigerator and a control method of the same are disclosed, wherein the refrigerator comprises an ice tray for receiving water to generate ices; a motor capable of being rotated in a forward or reverse direction; an ejector including a rotary shaft rotating the ices made in the ice tray to discharge the ices from the ice tray, rotated by being axially connected to the motor, and a protrusion pin protruded in a radius direction of the rotary shaft to adjoin the ices; a heater for selectively supplying heat to the ice tray; a door switching sensor for sensing a storage compartment door's opening or closing, the storage compartment door being provided with the ejector; and a controller for turning the heater on or off in accordance with a rotation position of the ejector.

An improved locker seat includes a pair of spaced-apart upstanding sidewalls having a pair of lateral edges. A generally horizontal seat is disposed between the lateral edges of the sidewalls. In a first mode, an air source is connected to an airway formed within the seat to create an airflow. The airflow from the air source creates a first temperature differential to cool the seat. In a second mode, an external or internal heat source provides heat to a top surface of the seat, creating a second temperature differential to heat the seat. The first and second temperature differential are distributed across the top surface of the seat. The seat is hinged to be movable about the hinge between an open and a closed position.

A partition wall arrangement of a storage according to the invention comprises a wall element with a framework and a liftable wall element. The framework comprises a horizontal upper element and side element. The liftable wall element is arranged between the side elements and fastened to the upper element. The partition wall arrangement further comprises a horizontal beam in connection with both side elements. The beams are parallel to each other and transverse to the wall element.

A packaged, pumped liquid, recirculating refrigeration system with charges of 10 lbs or less of refrigerant per ton of refrigeration capacity. The compressor and related components are situated in a pre-packaged modular machine room, and in which the condenser is mounted on the machine room and the evaporator is close coupled to the pre-packaged modular machine room. Prior art large receiver vessels may be replaced with a single or dual phase cyclonic separator also housed in the pre-packaged modular machine room.
