RIT,
no link to the vid. All I see is a blank panel with your name on it.

I've emailed him for a write up and more details

Link doesn't work

There is a space in the link. This forum software seems to have a part working module to embed youtube videos - so if the link is fully working it gets removed, but the embedding process does not correctly add the video to the forum post.

So the 'fix' is for posters to break the link - my solution being the adding of a space within the url.

An excellent youtube video. Informative and well explained.

He touched upon the water gain of Calcium chloride dessicators. Sold in the UK as a poor mans dehumidifier. These play havoc when they overflow and dripping through a floor to the ceiling below and not drying out.

Not sure if the Gentleman was from the US or Canada. Working in SI units was a great help.

So which German company is developing / marketing the aforementioned air conditioner? Bosch Buderus, Viessmann, or Vaillant?

They're working on a scaled up and improved system to cool their workshop. I'm looking forward to that!

I will watch the related youtube vids next week sometime. The Gentleman is very knowledgable and his demonstration apparatus is top rate.

evaporative coolers have been around for forever

if you google bong coolers, using a big bit of pipe with a sprinkler head in the top and a fan blowing air up through it has been around for at least 20 years in pc water cooling

doesen't seam to be anything new?

Yep, had one of these in Baghdad in 1982.

Initially I thought it was the water screen that was cooling the air but once I'd checked the kit out realised that the water screen was just to trap the dust which was a real issue. The filter for the water and the settlement tank had to be cleaned regularly to avoid the incoming air smelling like a wet dog.

The desiccant bit is the new thing. The final column is just a 'swamp cooler', which may be the same as your 'bong cooler'

2 main differences, firstly this solution/project deliveries 'conditioned air' where both heat and moisture have been adjusted and secondly it high efficiency while doing that task.

If anyone wants to see a bong cooler project can watch this
