Hey..I would like to know about cargo hold ventilator designs and details about how they work?

Question

I am a 2nd year student at a Maritime University. Although I found some cargo hold ventilator designs and details about how they work in my university library, I think I didn't get enough.. I guess there may be some up-to-date designs and theories still left. So if you have some knowledge about that item, please share me or point me out a website address where I can find all I need.

Ventilation arrangement for a cargo ship
United States Patent 4428318

A ventilation arrangement for a cargo ship includes at least one air circulation system for circulating air from a ventilation source into and out of the cargo. The ventilation source may include a refrigeration plant. The circulation system includes air supply and air exhaust ducts in the cargo hold. Container guides are located in the hold for receiving and aligning a number of cargo containers adjacent at least the air ducts. The container guides are also useful for receiving and positioning a plurality of cargo pallets; each pallet has a load-bearing surface on which break-bulk and other cargo can be placed. Each pallet load-bearing surface is defined by a hollow ventilation base which, as the pallet is positioned in the container guides can be connected by a suitable connection to an adjacent air supply duct. Openings are provided through the load-bearing surface of each pallet from the interior of the base for flow of air from the base into the cargo area of the pallet.
