I am confused by your explanation, pictures would help...

so we can learn from the
master how to do it?

still being childish eh

Time to put up or shut up.

I have already described what I do here in this thread. It's as basic as it gets.

For the benefit of those unable to read:

I use a crude swamp cooling setup here when it hits heatwave. It works and costs near nothing. We did have 2 or 3 days when it was raining real hard & you don't get significant cooling, the rest of the summer it's good. And no, it doesn't make indoors any damper.

But you never explained how a "crude swamp cool" wouldn't "make indoors
any damper". I concede you proposed a "complex swamp cooler" that
incorporated heat exchangers and the like.

What I do here (in heatwaves only) is far cruder. The flat roofed extension, despite being fully insulated, is like an oven in a heatwave. Flood the roof with water & that effect stops.

Which is not generally described to be a "swamp cooler".

There are many ways the swamp cooling principle can be used, and one that is most popular. Of course the above is not the most popular one, it's a cruder approach.

It is immensely
inefficient if the roof has any insulation.

depends how you define efficiency. In terms of action & power required to cool the house, it's good on efficiency, despite most of the cooling effect being lost to the wind.

I can only assume you have
insufficient insulation,

It's plenty for all except the absolute worst heatwave days - on those it's not.


certainly a lot less than you credit,

you're making it up again.


if you feel the cooling effect is significant.

It no longer heats some of the rest of the house. It could hardly be simpler, and no, no water vapour is added to indoor air.

But not a "crude swamp cooler".
