Seriously the frozen milk jug IS a heat exchanger and I guarantee that there will be a puddle of condensation at the bottom of that in no time flat, that is if there is any measurable amount of humidity in the air.
If you were to take that base design put the holes on the bottom about .5 inch off the bottom of the liner (which I think to be completely moot as you are blowing room air through it with out a cycle timer or thermostat). Now put a grate on top of the PVC pipes. then put your icy heat absorber (frozen milk jug in the video) on top of that. If you wanted to increase the efficiency of heat transfer use frozen water bottles and arrange them in a hexagonal pattern for more surface area and air throughput. Also I would suggest a large computer fan instead of that beast.
This type of thing seems like it would be best served for parties and weekend trips as that will quickly be a lot of work to stay slightly cooler.
