DIY Air Cooling! An Evap Air Cooler that produces cool air without adding humidity! it's easy to do! All Evaporative Air Coolers are classified as either "direct" or "indirect". currently, 95%-98% of the ones in use are the DIRECT type. this video shows how to set up an INDIRECT unit! Indirect systems are different in that they don't need any ventilation and, most importantly, don't add ANY Humidity to the inside air! they just pump out cool air! (*in dry or semi dry areas it feels the same as regular air conditioning). the unit itself is actually a two-part system and is made by combining two of my previous project videos (both easy DIY's). note that each project is a fully functioning air cooler on its own *but when combined they make a powerful indirect cooling unit! this video contains lots of info on how and why these systems work (plus how it compares to a "window style" AC unit). full instructions on how to build both parts (both units) are posted in separate (previously posted) videos (links to those videos are posted below).

Power Draw: 97 watts (measured with a 'kill-a-watt' meter). box fan/low speed = 47 watts. black fan/full speed = 35 watts. water pumps combined = 15 watts.

TIP: if you want to go even further you can turn this unit into a Two-Stage 'indirect' evap air cooler! (Two stage means that you're also using the humid 'exhaust air' to increase the units overall performance). one easy way to do this would be to direct the humid air onto the pipes that are entering and exiting your home. doing that adds the 'second stage' and helps increase the units efficiency.

IDEA: want a temporary blast of SUPER COLD air? drop some ice in the water. (that makes it an evap/conduction cooler hybrid for extra cooling.

NOTE: also included in this video is footage of two "solar panel powered" systems i've made. these setups can be run 'off-grid' using only a 12v solar panel (or a 12v battery)!
