Gary has an interesting cooling setup for his shop he is playing around with. It reminds me vaguely of my project
using sump water to cool the house. His setup is more simplistic though (a good thing). He is simply using a fan to vent air out of his shop and routing that air past some 50 gallon plastic barrels filled with water. This cools the barrels overnight and when things warm up the fan can be used in reverse to blow air over the barrels and keep the shop cool. He goes through all the thermal mass calcaultions on the site. He is looking for suggestions to improve the system.
Night Air Thermal Mass Cooling Using Water Barrels
A few barrels against the wall.
Add some ducting around them to route more air directly over them.
