Then again, 22C is cool, but comfy (PMV = 0.007), with vel = 0.1
m/s and clo = 1 insulation. Raising vel to 0.5 and lowering clo
to 0.5 makes 35 C at 65% comfy (slightly cool, with PMV = -0.54,
on a scale from -3 = cold to +3 = hot), according to the BASIC
program in the ASHRAE 55-2004 comfort standard, so he might have
just used a ceiling fan on that day... 28C at 35% with clo = 0.5
and vel = 0.5 is "slightly
warm" in the comfort zone, with PMV = 0.23.

A properly designed swamp cooler system can run with
just the fan and no water, no need for extra ceiling fans.

If you're running it with a fan and no water, it's a ... fan.

Duh.

Swamp cooling relies on the fact that water evaporation cools
nearby air.

Duh.

You pull outside air into the wet medium, and pump the cooler and
more humid air through the house. It then exits the house through
open windows

Duh. Pity that post was clearly suggesting ceiling
fans IN ADDITION TO A SWAMP COOLER.

(to the poster who recommended closing all the windows,
that's going to completely undermine the whole thing).

He's too stupid to be able to work that out for himself.

anyone read Rex Robert's book? "Your Engineered House"
advocates natural air flow. Low vents and high exit vents to promote
the natural air flow as heat rises.

Thats fine as long as the temp doesnt get too high.

Doesnt work anything like as well as a decent swamp
cooler when you have 10 days over 40C/105F tho.

We love ceiling fans too. And a light color for the roof.
the garage sports a wind turbine. Cool!

Not when you have 10 days over 40C/105F tho.
****ing hot in fact.
